INDUSTRIAL CENTRIFUGE SEPARATOR WORKING PRINCIPLE
https://www.saideli-centrifuge.....com/principles-of-t

The centrifugal separator working principle is fed tangentially to the cylindrical top of the centrifugal separator to produce rotation. Through the slot in the air inlet chamber, the flow rate in industrial centrifuge is further accelerated. Centrifugal force moves the heavy particles to the side of the barrel. They move down and accumulate in the collection chamber at the bottom of the separator. The deflector at the top of the collection chamber changes the flow direction. No solid liquid moves upward in the vortex and exits through the top of the separator. The separated solids are removed from the collection chamber periodically or continuously.

What Is Centrifugation And Where It Is Used?
The centrifugal separator is driven by centrifugal technology. Centrifugation uses centrifugal force to separate particles from solution. This process is mainly used to separate two immiscible substances in the solution. Centrifuge is mainly used to separate solid particles from liquid in suspension; or to separate two immiscible liquids with different densities in emulsion (such as separating cream from milk); it can also be used as solid liquid centrifugal separator, such as drying wet clothes with a washing machine; special ultra-fast tube separators can also separate gas mixtures of different densities, such as enrichment and separation of gaseous uranium hexafluoride; Due to the characteristics of different sedimentation speeds in the liquid, some sedimentation centrifuges can also classify solid particles according to density or particle size. The centrifuge separator is widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding sectors.

Centrifugal Separator Working Principle
Centrifuge separator machine has a high-speed rotating cylinder, called a bowl, around its axis, usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is rapidly driven to rotate at the same speed as the drum, and the components are separated and discharged separately under the action of centrifugal force. In general, the higher the drum speed, the better the separation effect. Pharmaceutical centrifuge separator manufacturers usually offer two types of centrifuge separators for sale: centrifugal filtration and centrifugal sedimentation. Hence there are two industrial centrifuge working principles.

(1) Centrifugal filtration

The centrifugal pressure generated by the suspension under the centrifugal force field acts on the filter medium (filter screen or filter cloth), so that the liquid passes through the filter medium to become filtrate; while the solid particles are trapped on the surface of the filter medium to form a filter residue, thereby realizing liquid-solid separation. There are holes on the circumferential wall of the filter drum, and the inner wall is lined with filter media, which is centrifugal separator working principle.

(2) Centrifugal sedimentation

Liquid-solid (or liquid-liquid) separation is realized by utilizing the principle of rapid sedimentation and stratification of components with different densities of suspension (or emulsion) in a centrifugal force field. The peripheral wall of the sedimentation drum has no holes. After the suspension (or emulsion) is added to the drum, the solid particles (or liquid with higher density) settle to the drum wall to form a sediment (or heavy separation liquid). The liquid with lower density gathers in the direction of the center of the drum, flows to the overflow port for discharge, and becomes the separation liquid (or light separation liquid). The rotary drum filter is used for intermittent slag discharge, which is suitable for the separation of suspensions or emulsions with small particle size and low concentration of solid particles. In the drum with multi-layer conical discs, the liquid is divided into several thin layers by the discs, which shortens the distance of sedimentation separation, accelerates the separation, and improves the separation effect.

When the solid and liquid mixture to be separated enters the high-speed rotating drum from the feeding port, under the action of centrifugal force, the mixture is filtered through the filter screen, the liquid separation is discharged through the drain pipe, and the solid separation is left in the drum. Inside, when the solid separation in the drum reaches the requirements specified by the equipment, stop feeding, clean the solid separation, and discharge the washing liquid at the same time. After the cleaning meets the requirements, the centrifuge separator runs at a low speed, and the solid separator discharge device (scraper) is driven by the AC servo motor to discharge the solid separator to complete a working process.

OPERATION AND CONTROL MANAGEMENT OF HORIZONTAL DECANTER CENTRIFUGE IN WASTEWATER TREATMENT PLANT
https://www.saideli-centrifuge.....com/operation-and-c

Non-adjustable mechanical factors of horizontal decanter centrifuge

Drum diameter and effective length

The larger the volume of sedimentation treated by effective conveying, the stronger the precipitation handling capacity will be. Also, the longer the retention time of material molecules in the drum chamber of the industrial centrifuge, the greater the separation resistance coefficient, and the better the efficiency of centrifugation under the same speed. However, due to the influence of the size of material shape, the maximum turning radius of the centrifuge drum plate in a horizontal centrifuge will not increase without limit, because the maximum allowable speed has been reduced due to the increase in diameter and the decrease in centrifugal force.

Drum

The drum can be divided into deep liquid pools and shallow liquid pools according to its shape. The deep liquid pool is used to process sludge and pasty materials. The principle is that the high torque generated by the screw compresses the settled material to dehydrate the sludge. The shallow liquid pool is used to process rough and internally gapped particles of sediment, so that water can pass through the particle gaps and discharge to the solid phase for dehumidification.

Design of screw

The pitch of the screw refers to the relative horizontal distance between two rotating screw blades of the machine and two adjacent spiral blade diameters of adjacent machines. It is often an important process structure parameter in the entire equipment, and it determines the speed of screw conveying. The easier the settling substance is to be conveyed, the larger the pitch can be. The pitch will directly affect the outcome of the sludge conveying work.

When the diameter of both rotating wing screws of the machine reaches a certain height, the larger the pitch value, the larger the helix angle value, and the greater the conveying opportunity of the sludge is blocked between adjacent spiral blade diameters. At the same time, increasing the pitch will reduce the number of rotations of the screw blade diameter, making it difficult for the sludge to reach a uniform state of distribution between the cone end blades of the screw drum. This will cause the internal vibration and pressure of the entire screw machine to increase.

In order to facilitate the effective transportation and separation of sludge, the pitch angle should not be too large. The best range for industrial centrifuges is about 6 degrees or less to reduce the sludge's transport backflow or separation speed.

Material of equipment

Parts that come into contact with materials and their volatile vapors must be made of materials that are resistant to chemical and physical corrosion. In special projects, high-nickel-based alloy materials may be used if required on site. Attention should be paid to factors such as the chemical concentration of the material and the operating temperature during operation.

Adjustable mechanical factors of horizontal decanter centrifuge

Drum speed

The adjustment method of the drum speed, which determines the high or low speed of the drum, is currently usually achieved by multi-motor three-phase AC variable frequency motors, direct adjustment, or by driving the rotation direction of the hydraulic motor. The higher the speed requirement, the stronger the centrifugal force, which is beneficial to quickly increase the soluble solid content on the surface of the cement cake.

However, the usually high requirements for drum speed can often cause moisture damage and sludge cohesion, reducing the final dewatering and purification of sludge. At the same time, the relatively high-speed requirements for the entire material conveying device use three-phase motors, which cause large wear areas in the entire three-phase machine system, large changes in power parameters, large power consumption losses, and large vibration noise losses. All these factors increase the wear and tear on the system.

Differential speed ratio

The speed difference directly affects the strength of sludge discharge, the cake degree of mud, and the quality of screened liquid, and is one of the key technical parameters that must be adjusted according to the working conditions of the horizontal screw industrial centrifuge machine. Although increasing the differential speed can increase the sludge discharge capacity, it will also reduce the dehydration time of sediment, resulting in high moisture content of the dehydrated mud cake.

There is a certain contradiction between improving the capacity of sludge treatment and improving the effect of sludge treatment. In order to effectively improve the treatment capacity of sludge, it is necessary to further increase the difference between mud and speed, and appropriately reduce the dryness of mud. Therefore, on-site simulation adjustment work should be carried out to find the best differential speed range according to the material properties, processing capacity, processing requirements, and the structural parameters of the centrifuge in industry, in order to achieve the highest processing capacity under conditions that meet the mud dryness.

COMMON ISSUES WITH HORIZONTAL CENTRIFUGE MACHINES IN WASTEWATER TREATMENT PLANTS
https://www.saideli-centrifuge.....com/issues-with-hor

Horizontal Centrifuge Machine (Horizontal Spiral Discharge Sedimentation Centrifuge) is mainly composed of a drum, a screw, a differential system, a drive system, and a control system. In the process of sludge dewatering in sewage treatment plants, Horizontal Centrifuge Machine is widely used. Despite the differences in model specifications, equipment structure, materials, and operating parameters among various manufacturers, their working principles are basically similar, using centrifugal force to accelerate solid sedimentation for solid-liquid separation.

The Clogging Issue of Horizontal Centrifuge Machine

In actual operation, horizontal centrifuge machine often faces clogging issues, manifested as poor solid discharge or complete blockage. These phenomena include increased current, dull operation sound of equipment, and uneven solid phase discharge. When completely clogged, the equipment may alarm and shut down, requiring timely handling.

Causes and Solutions

Unreasonable equipment structure. If the taper angle is too large, the pitch is too large, etc., due to equipment reasons, if the structure is unreasonable, the user themselves cannot solve it;

Operating parameters not matching the site conditions; such as differential control, drum speed, etc. The solution is to stop feeding, wait for the equipment to run for a few minutes, then adjust the drum speed (generally slowing down the drum speed), increase the differential speed, and feed a small amount of material for separation. Once the equipment operation is stable, increase the feed amount.

Poor Dehydration Effect of Horizontal Centrifuge Machine

Poor dehydration effect means a high moisture content in the solid phase, affecting forming and transport capacity. This may be caused by poor flocculant performance or improper setting of operating parameters.

Solutions

First, check if the flocculant performance is normal and if permeability is good. If the flocculation effect is poor, it is difficult to meet the working condition requirements for dehydration, and the dosage is large, resulting in high operating costs. Finding a suitable flocculant greatly helps improve dehydration effect and reduce operating costs.

Adjust operating parameters to improve dehydration effect by increasing drum speed or adjusting differential speed to improve dehydration efficiency, replacing the flow regulation plate, thereby achieving the desired dehydration effect.

Low Handling Capacity and High Operating Cost of Horizontal Centrifuge Machine

Due to different equipment structures from various industrial centrifuge machine manufacturers, the handling capacity of the same model can vary significantly. The handling capacity and medication dosage directly affect the increase in operating costs. When purchasing a Horizontal Centrifuge Machine, it is crucial to choose a manufacturer with strong production capacity, good after-sales service, and high cost-performance ratio. Choosing a good partner is the most economical and low operation cost factor for users.

By solving these common issues, sewage treatment plants can improve Horizontal Centrifuge Machine efficiency and reliability, reduce operating costs, and ensure smooth environmental protection work.
