Flottweg- Solid Bowl Decanter Technology

Innovative Solid Bowl Decanter TechnologySolid bowl centrifuge technology Modern centrifuges are used in technical processes for the mechanical separation of mixtures of solids and liquids. Sedimentation, centrifugation, and filtration are mechanical separation processes, in con- trast to distillation, incineration and thermal drying, which are thermal separation processes. In many processes, mechanical separation is primarily responsible for product quality, production efficiency and envi- ronmental control. Mechanical separation processes are found in practically all industrial sectors, including food, chemical, pharmaceutical, biotech, mineral, and environmental. Advantages of modern centrifuges Modern centrifuges have many advantages in comparison to other separation processes such as filtration and sedimentation. Compact designs, sealed construction to control odor emissions and avoid contamination of the product, ease of operation with continuous or automatic control systems, and limited replaceable operating parts such as filter media or filter aids make centrifuges advantageous to use. 2 i.e. such as the DECANTER. FLOTTWEG CENTRIFUGES can more effectively help one reach their processing goals by offering a variety of basic designs. ® = registered trademark in various countries 3 .

The utilization of electronic and electromechanical measuring and control components has improved the performance and availability of the machines.Solid bowl centrifuges The basic principle of the solid bowl centrifuge has been known since the end of the 19 century. The basic design of a solid bowl centrifuge is relatively simple and can be customized by FLOTTWEG for different requirements. Over the th materials have allowed solid bowl decanters to be applicable to many processes. technology improvements along with the availability of high strength and corrosion resistant raw 5 . course of time. solid bowl centrifuges have the broadest range of application. Of all modern industrial centrifuges. The slurry rotates with the bowl at the operating speed and forms a concentric layer at the bowl wall. This differential speed determines the residence time of the solids in the bowl. The solids contained in the slurry are deposited against the bowl wall by centrifugal force. Bowl The bowl has a cylindrical/ conical shape and rotates at a pre-set speed optimal for the application. The product is then accelerated circumferentially and delivered through distribution ports into the bowl. Residence time is an important variable for the dry solids content. Scroll pitch and single or multiple flight configurations are important design variables. 6 . The length of the cylindrical bowl section and the cone angle are selected to meet the specific requirements of an application. Scroll The scroll rotates at a slightly different speed than the bowl and conveys the deposited solids toward the conical end of the bowl. FLOTTWEG DECANTERs can be supplied feed inlet solids discharge FLOTTWEG DECANTER for the liquid-solid separation with gravity overflow of the liquid phase (centrate) liquid discharge by gravity Eccentric – adjustable weir plates (patented) with a different scroll design or by modifying an existing scroll. If the physical properties of the slurry change. It can be adjusted by changing the differential speed of the scroll thus providing optimal separation.FLOTTWEG DECANTER CENTRIFUGES Feed The slurry is fed through a stationary pipe into the feed zone located in the center of the scroll. Overflow weirs The clarified liquids flow to the cylindrical end of the bowl where they exit over weir plates. The FLOTTWEG adjustable impeller is an engi- neering refinement that permits quick and precise adjustment of the pond depth during operation to accommodate changing conditions. Bowl and scroll castings are made from centrifugal cast high strength and corrosion resistant stainless steel. Overflow is then collected in a centrate chamber and discharged by gravity. liquid discharge under pressure feed inlet solids discharge FLOTTWEG DECANTER with pressurized centrate discharge Adjustable impeller 7 . Materials of construction FLOTTWEG uses high-quality stainless steel for all wetted areas. Easily adjustable precision weir plates allow for the precise adjustment of the pond depth in the bowl. This eliminates the need for a separate centrate pump. Rotor bearing A special selection and arrangement of bearings provides long life and exceptional reliability.Solids discharge Settled solids are ejected through ports at the conical end of the bowl into the solids housing and fall through to the discharge chute. A central lubrication system supplies either grease or oil to bearings. Impeller (skimmer) The clarified liquid can also be decanted with an impeller and discharged from the bowl under pressure.

This optimizes purity of the liquids and may possibly eliminate downstream equipment. The most important difference from a decanter is the separate discharge of the two liquid phases.e. The FLOTTWEG TRICANTER® discharges the heavy liquid through an adjustable impeller under pressure and the light phase by gravity. The adjustable impeller allows adjusting the separation zone and degree of separation within the machine during operation. Carrier liquids with different densities enable the user to shift the effective interface zone. The patented FLOTTWEG SORTICANTER consists of a ® scroll conforming to the inner contour of the bowl. The solids which are lighter than the carrier liquid float and are conveyed with the liquid toward the cylindrical end of the bowl. over the drying zone and ejects them through ports into the stationary solids housing and down the discharge chute. Centrifugal force causes the solids which are heavier than the carrier liquid to settle against the bowl wall. The solid-liquid mixture is conveyed through the centrifuge feed pipe and inlet ports in the scroll body into the bowl and accelerated to the bowl speed. When the floating par- cylindrical conical bowl with a second inner cone at the cylindrical end and a double acting liquid discharge under pressure feed inlet solids discharge heavy phase FLOTTWEG SORTICANTER® for plastic recycling solids discharge light phase ticles have reached the second inner cone. liquid may be recycled as carrier liquid.FLOTTWEG SORTICANTER® The innovative FLOTTWEG SORTICANTER® is designed for the separation of solids by density. The process is aided by a carrier liquid with a specific gravity that is between the densities of the two solid streams to be separated. After an intermediate cleaning step. ® = registered trademark in various countries 9 . The liquid is skimmed off and discharged under pressure by an impeller at the cylindrical end of the bowl. The scroll conveys the deposited layer of heavy solids toward the conical bowl section. The bowl and lagging scroll rotate at a high speed in the same direction. scroll flights wound in the opposite direction to those conveying sedimentated solids transfer the lighter solids across a drying zone to the exit ports. The SEDICANTER is used in ® the liquid and solids move in the same direction without having to pass through a turbulent inlet zone. protein suspensions and fermentation broths.

Depending on the application. Their compact design (controls. The volume flow of the oil determines the bowl speed and the differential speed of the scroll. On one hand. Control and adjustment are the same as with the hydraulic drive. FLOTTWEG frequency controlled electric motors or speed-adjustable hydraulic motors offer infinitely variable speed. This ensures optimum adjustment to meet individual customer requirements. This drive per- mits the use of variably adjustable control. Hybrid drive In this version. 12 . a frequencycontrolled electric motor drives the bowl instead of a hydraulic motor. The hydraulic aggregate for the scroll is compact because only one oil circuit is required. A compact hydraulic aggregate with two variable pumps feeds two separate oil circuits. and on the other hand. monitoring and analog control. Fully hydraulic drive Hybrid drive Frequency inverter drive (VFD) Fully hydraulic drive The bowl and the scroll are driven by separate hydraulic motors.Drives General Decanter centrifuges are subject to two conflicting basic drive requirements. the entire rotor has to run at high speed. Long start-up times help overcome a high inertia moment and avoid peak loads during the initial current phase. FLOTTWEG offers hydraulic motors or gear drives to drive the scroll depending on the application. Hydraulic drives offer particular advantages for applications in mobile processing systems. The drive’s design enables independent rotation of the scroll even when the bowl is shut down. whereas the oil supply pressure is directly proportional to the torque output and thus to the load. The majority of the drive configurations offer variable differential speeds. Another advantage is applicability in explosion proof areas. aggregate) provides for optimal utilization of floor space. the scroll inside the bowl has to rotate at a very low differential speed and simultaneously at a high torque relative to the bowl wall. A frequency-controlled electric particularly suited for separation V-belt drive. controls the differential speed in relation to the scroll torque. The differential speed can be Bowl drive Scroll drive Backdrive with Dual-VFD SIMP-DRIVE® SIMP-DRIVE® The FLOTTWEG SIMP-DRIVE ® dryness.ferential speed. ferent transmission ratio powers a cycloid planetary gear and generates the differential speed of the scroll. Backdrive with Dual-VFD This solution is derived from the FLOTTWEG gear drive with the scroll drive having its own frequency-controlled motor. The main feature of this new concept is a multistage planetary gear which Benefits include: • High efficiency and low energy demand • Simple integration into process control systems • Smallest possible inverter size • High flexibility in the selection of the operating speed • Discharge of the bowl even at full stop • Applicable for small to medium differential speeds • Low power draw.Gear drive with frequency inverter motor drives the bowl via a The FLOTTWEG gear drive is the most basic drive solution and is processes which do not require separately adjusted with a preset range and controlled and monitored independently of torque. The differential speed can be changed and adjusted by changing V-belt pulleys. which is power-linked via a regenerative circuit. Both drive motors are powered by a FLOTTWEG frequency inverter. high solids ® = registered trademark in various countries 13 . Therefore the decanter adapts itself to varying load conditions and dewaters the product in order to reach maximum cake allows for entirely independent • A simple drive system not operation and drive of the bowl requiring linkage and scroll (similar to a hydraulic drive) • Independent frequency inverters (VFDs) which are standard designs.

Centrifuge controls Fluctuations of the solid throughput and concentration in the centrifuge may cause a decrease in separation results. the feed supply is stopped until when the torque reaches the 14 ® = registered trademark in various countries . Load and torque should be kept at an optimum value. blockage or an overload of the centrifuge. this is sufficient to remedy the overload without having to shutdown the system. Typically there is no need for manually removing the solids. This automatic control process ensures optimum separation during normal operation. In the majority of situations. Machines with hydraulic drive or SIMP-DRIVE® enable solids discharge at full-torque scroll operation during the bowl shut down. FLOTTWEG offers control systems for the differential speed which are based on the following principle. the torque is reduced and the machine will usually empty itself. If this measure is insufficient to keep the scroll torque from rising. An integrated two-stage overload protection offers excellent control of the machine resulting from process deviations. the differential speed needs to be continuously adjusted for operating conditions. the FLOTTWEG control system increases the differential speed to convey the solid faster out of the bowl until the torque decreases. the bowl drive is shut down second set point. If the torque exceeds the optimum value. Scroll torque is a measure of bowl solids load. To avoid problems and to fully utilize the capacity of the centrifuge. As the bowl speed decreases. the differential speed is reduced when the torque decreases. Process control system If the increase in differential speed is not sufficient to compensate for a solids overload. Conversely. the torque falls back below set point. you can be certain that all of your future challenges can be solved easily.

As a manufacturer of our control panels. Special sealing elements minimize the seal gas consumption. Atmospheric Vapor-tight Gas-tight Gas-tight centrifuges allow the safe operation with toxic. Slight positive or negative pressures can be maintained in the process area by regulating the purge gas supply. corrosive or flammable media by applying inert purge gas to rotor seals and by inertizing the process chamber and centrifuge housing. Emissions can be eliminated when purge gas/air is applied to seals or the centrifuge housing is vented. 16 . Additional seals on rotor shafts and housing provide the necessary seal. Atmospheric centrifuges are the standard version.Sealing systems Most sizes and models of FLOTTWEG CENTRIFUGES are available in a variety of rotor and housing seal designs for the following operating conditions: • atmospheric • vapor-tight • gas-tight FLOTTWEG CENTRIFUGES can also be adapted for operating in closed-loop systems. They are used for applications where there is no harm from products or vapors released to the environment and where it is not necessary to isolate the centrifuge bowl from the surrounding atmosphere. Vapor-tight versions of FLOTTWEG centrifuges are the right choice in cases where substances emitted from the process could pollute the environment or if contact of the product with ambient air is undesirable. This prevents atmospheric air from penetrating into the system. Centrifuges and system parts used for the processing of hazardous materials have to be gastight to prevent the exit of vapors into the atmosphere as well as to avoid the entry of air into the system. up to temperature class T3. This ensures a small overpressure within the sealing system and the inside of the centrifuge guaranteeing protection against air leakage into the system and product emission into the atmosphere. a fixed constant overpressure in the sealing system using control vales is maintained. In many cases. These centrifuges comply with ATEX 95 in Zone 1. Rotor Seal Housing FLOTTWEG purge gas control unit Control of centrifuges purged with inert gas is based on a differntial pressure monitoring system with integrated automatic control. petroleum. Typical examples are processes in the chemical. Purging is complete if a multiple of the system volume has passed through the machine or if an oxygen probe at the centrifuge housing shows a safe oxygen concentration. Thus. Continuous inert gas supply After successful purging and during the operation with product. carbon dioxide is used as the inert gas. Purging Before starting. For this purpose the leakage of air into the centrifuge is prevented by corresponding constructive measures and positive inert gas pressures are maintained at the centrifuge. processes with flammable organic solvents or oil sludge treatment processes. the entire system including the centrifuge is purged. 17 . Generally. nitrogen is used. and pharmaceutical industry. large volumes of inert gas are flushed through the system until the oxygen is reduced below critical level with the inert gas. For this purpose.Purging with inert gas Processing of hazardous materials Processes with any risk of explosion must be controlled by using inert gas. A system monitoring the flow of gas is typically used. Processing of materials susceptible to oxidation Often the processing of beverages and food requires that products be prevented from undergoing oxidation. sufficient inert gas is fed into the system to ensure a small overpressure. Manual readjustment is not required anymore. The lubrication system depends on the type of operation.or overlubricated and rules out shortterm spikes in bearing temperatures and excessive grease consumption. It prevents bearings from being under. Optimum lubrication is achieved at high speeds. 18 . The grease pump is automatically controlled. The scroll bearings are permanently sealed and lubricated. an airoperated oil droplet lubrication system is supplied. with low oil consumption and no loss in performance. for example. Automatic grease lubrication In contrast to the manual central lubrication system. the greasing system can be automatically activated. Automatic oil droplet lubrication system The fully automatic oil-air lubrication system ensures optimal lubrication with oil droplets transported via air to the bearings. but can also be re-greased manually. The lubricant is dispensed proportionally through a special piston distributor. They are suited for Zone 1 up to temperature class T4 according to ATEX 95. Pneumatic designs are available for utilization in explosion-proof areas. batch or continuous operation and the degree of automation of the entire system. For many applications.Lubrication FLOTTWEG CENTRIFUGES can be provided with different lubrication systems. Central lubrication system (manually operated) Automatic grease lubrication Oil droplet lubrication system This ensures the uniform and reliable lubrication of the centrifuge. This system does not require oil recirculation or treatment. Central lubrication system All main lubrication points are permanently manifolded via tubing or hoses to a central pump.
