　　Oil sludge separation equipment - horizontal screw centrifuge

　　What is the sludge separation equipment? It mainly refers to a high-tech equipment that can separate solid and liquid phases in sludge. In the industry, it is commonly known as a horizontal screw centrifuge.

　　I. Overview

　　Oil sludge separation equipment is a horizontal spiral discharge and continuous operation settling equipment.

　　The working principle of this type of separator is as follows: the drum and the screw rotate at a certain differential speed and high speed in the same direction. The material is continuously introduced into the inner cylinder of the conveying screw through the feeding pipe, accelerated and enters the drum. Under the action of the centrifugal force field, heavier solid substances deposit on the drum wall to form a sediment layer. The feeding spiral continuously pushes the deposited solid phase to the cone end of the drum and discharges it outside the machine through the slag discharge outlet. The lighter liquid phase forms an inner liquid ring, which continuously overflows from the large end overflow port of the drum and is discharged outside the machine through the discharge port. This machine can continuously feed, separate, wash, and discharge materials at full speed. It has the characteristics of compact structure, continuous operation, smooth operation, strong adaptability, high production capacity, and convenient maintenance. Suitable for separating suspensions containing solid particles with a particle size greater than 0.005mm and a concentration range of 2-40%. Widely used in industries such as chemical, light industry, pharmaceuticals, food, and environmental protection.

　　2、 Working principle

　　The suspension enters the sludge separation equipment from the feed pipe, and under the high-speed rotation of the drum, heavy solids are thrown towards the drum wall, while light liquids are squeezed towards the center of the drum. Under the differential speed between the screw and the drum, the solid settled on the drum wall is pushed towards the slag outlet at the small end of the drum by the screw conveyor and discharged outside the machine, while the liquid is discharged outside the machine through the overflow hole at the large end of the drum.

　　3： Selection of Horizontal Spiral Centrifuge

　　Choosing the appropriate oil sludge separation equipment can not only solve the problem of sludge separation and improve work efficiency, but also save production costs and reduce business risks. The main factors affecting selection are as follows:

　　1. Speed of oil sludge separation equipment: Generally, the speed of oil sludge separation equipment should be above 3000 revolutions per minute. The higher the speed, the higher the separation factor of the oil sludge separation equipment, and the better the separation effect.

　　2. Material of oil sludge separation equipment: Different materials have different physical and chemical indicators such as wear resistance and corrosion resistance. Foreign oil sludge separation equipment is generally made of 316L or duplex stainless steel, and abrasive components must be made of ceramic composite materials.

　　3. Differential control of centrifuge: Different differentials have different control accuracies, and there is a significant difference in lifespan and maintenance costs. The higher the differential accuracy, the better the adaptability to materials. Therefore, it is advisable to choose equipment with high differential accuracy.

　　4. Length to diameter ratio: The larger the length to diameter ratio of the oil sludge separation equipment, the greater its processing capacity and the lower its moisture content.

　　5. Control system: Is it automated programming control? Currently, domestic and foreign equipment manufacturers have basically achieved full automation control of the equipment.

　　6. Installation power: affects the control of energy consumption. Generally, domestic equipment has a higher energy consumption ratio, while foreign equipment has a lower energy consumption ratio.

　　7. Processing and manufacturing technology: Oil sludge separation equipment is a separation equipment that requires high-precision processing. Enterprises that do not have precision processing capabilities have high maintenance rates and limited processing capabilities for their products.
