Product Description Product Description Stainless steel 304 continuous mud decanter centrifuge for liquid solid separation with high qualityMud decanter centrifuge is referred to as the horizontal screw centrifuge, which is a horizontal spiral discharge, continuous operation of high-efficiency centrifugal separation and dehydration equipment. Type: Horizontal screw centrifuges can be generally divided into horizontal spiral filter centrifuges and horizontal spiral sedimentation centrifuges. Scope of application: The horizontal screw centrifuge is suitable for dewatering sludge produced in industrial and civil sewage treatment, and is also widely used in chemical, light industry, pharmaceutical, food, environmental protection and other industries. mud decanter centrifuge Working principle:the drum and the spiral rotate at a high speed in the same direction at a certain speed. The material is continuously introduced into the conveying screw inner cylinder by the feeding tube, and then enters the rotating drum after acceleration. Under the action of the centrifugal force field, the heavier solid phase deposit is transferred. A sediment layer is formed on the drum wall. The conveying screw continuously pushes the deposited solid phase to the cone end of the drum, and is discharged outside the machine through the slag discharging port. The lighter liquid phase forms an inner liquid ring, which overflows the drum from the overflow end of the drum end and exits the machine through the liquid discharge port. The machine can continuously feed, separate, wash and discharge at full speed.

This characteristic is dependent on the radius of the centrifuge and its angular rotational speed. A decanter centrifuge applies a force equivalent to several thousand G's, which reduces the settling time of the particles. It is also favored to maintain a large G-force, which wil result in an improved separation.The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process. The sedimentation rate is influenced by the particle size, the shapes of the particles, their differential densities and the viscosity between the particles and the liquid. This process characteristic can be improved by utilizing flocculating agents. The sedimentation rate is also dependent on the separating factor of the decanter centrifuge, which is related to the centrifugal force.The exterior bowl and the scroll conveyor rotate at different high speeds. This differential speed between the two is accountable for the sedimentation throughout the decanter centrifuge cylinder. A high differential speed results in a smaller residence time of the cake settlement, so it is necessary to keep the cake thickness to a minimum to avoid impairing the discharge quality.Keeping the cake thickness to a minimum also aids in the improvement of the cake dewatering process. For this reason, it is necessary to obtain an optimal differential speed to balance the cake thickness and quality.The characteristic above all affects the clarity of the liquid output which is dependent on the volumetric throughout rate, where a higher flow rate will result in a poor liquid clarity. Another characteristic that influences the clarity of the liquid output is the differential speed. A low differential speed results in a better clarity, therefore, aiding in the separation process. The G-Force also plays a role in the clarity of the liquid discharge. Higher G-force results in an increase in the separation of the solid particles from the liquid and yields a better clarity. How it worksHow does it workThe feed product is pumped into the decanter centrifuges through the inlet. Feed goes into a horizontal bowl, which rotates. The bowl has is composed of a cylindrical part and a conical part. The separation takes place in the cylindrical part of the bowl. The fast rotation generates centrifugal forces up to 4000 x g. Under these forces, the solid particles with higher density are collected and compacted on the wall of the bowl. A scroll (also screw or screw conveyor) rotates inside the bowl at a slightly different speed. This speed difference is called the differential speed. This way the scroll is transporting the settled particles along the cylindrical part of the bowl and up to the end conical part of the bowl. At the smallest end of the conical part of the bowl, the dewatered solids leave the bowl via discharge opening. The clarified liquid leaves through a paring disc (internal centripetal pump).3-phase separation with a decanterWith a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the production of biodiesel etc.Parameters and influencing factors of the separation Feed, throughput and residence timeThrough the feed, the separation medium to be processed can be input into the center of the infeed chamber of the scroll, where it is accelerated. The throughput will have an influence on the residence time.Decanter Centrifuges AccelerationThe separation medium reaches its maximum speed in the decanter bowl, causing the solids to settle on the bowl inner diameter. A characteristic feature of the bowl is its cylindrical/conical shape.Differential speedThere is a differential speed between the decanter bowl and the scroll, which is created by a gear unit on theindustrial decanter centrifuges. The differential speed determines the solid content in the outfeed.Filling volume / Weir discs or overflow weir The clarified liquid flows to the cylindrical end of the bowl in the decanter centrifuge, from where it runs out through openings in the bowl cover. These openings contain precisely adjustable weir discs/weir plates by means of which the pond depth in the bowl can be set. The weir discs determine the filling volume of the bowl.Advantages and limitations over competitive processesGenerally the decanter centrifuge has more advantages than disadvantages; however, there are some limitations when compared to other processes.Decanter Centrifuges Advantages:* Decanter centrifuges have a clean appearance and have little to no odor problems.* Not only is the device easy to install and fast at starting up and shutting down but also only requires a small area foroperation compared to other competitive processes.* The decanter centrifuge is versatile as different lengths of the cylindrical bowl section and the cone angle can be selected for different applications. Also, the system can be pre-programmed with various design curves to predict the sludge type, while some competitive processes, such as a belt filter press, cannot change the belt type to operate for different sludge types. Its versatility allows the machine to have various functions such as operating for thickening or dewatering.* The machine can operate with a higher throughput capacity than smaller machines. This also reduces the number of units required.* The device is simple to optimize and operate as it has few major variables and reliable feedback information.* The decanter centrifuge has reduced labor costs compared to other processes, as it requires low continuous maintenance and operator attention.* Compared to some competitive process such as the belt filter process, the decanter centrifuge has more process flexibility and higher levels of performance.Decanter Centrifuges Limitations:* The decanter centrifuges cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.* The machine can be very noisy and can cause vibration.* The device has a high-energy consumption due to high G-forces.* The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.Company ProfileLiaoyang Shenzhou Machinery Equipment Co., Ltd. belongs to Shenzhou international Group.
