In the process of low concentration sludge dewatering, Horizontal screw centrifuge It is a commonly used equipment. According to the research data, the low concentration municipal sludge passes through the recumbent snail Centrifuge After treatment, the average solid content of mud cake can reach 23.28%, and the average solid recovery rate is 99.41%. Therefore, horizontal spiral centrifuge has important application value in low concentration sludge dewatering.
The horizontal spiral centrifuge has a series of technical features, especially suitable for low concentration municipal sludge. According to experts, the operating parameters of horizontal spiral centrifuge have a significant impact on the solid content and solid recovery of sludge cake when it is used to treat low concentration municipal sludge. The solid content of sludge cake increases with the decrease of differential speed, and decreases with the decrease of sludge concentration.
Some main technical features of horizontal spiral centrifuge deserve our attention. First of all, the whole machine adopts an integrated structural design, which is small in size, small in floor area and convenient for operation and maintenance. Secondly, the design of the screw conveyor reduces the disturbance to the separation liquid and improves the separation effect. In addition, the horizontal spiral centrifuge also has excellent wear resistance and sealing performance to ensure that sludge, water and odor will not leak from the equipment.
Horizontal screw centrifuge Sludge treatment Main technical parameters in include drum diameter, rated working speed of drum, length diameter ratio, maximum speed of drum, differential speed, maximum separation factor differential mechanism Rated torque and main motor power, etc. These parameters can be adjusted according to specific processing requirements to achieve the best processing effect.
In view of the characteristics of low concentration municipal sludge, Chongqing Jiangbei Machinery Co., Ltd. has developed a suitable horizontal spiral centrifuge, and has achieved good results in engineering practice. This shows that the application of horizontal spiral centrifuge in the field of low concentration sludge dewatering is feasible and effective.
To sum up, horizontal spiral centrifuge is widely used in low concentration sludge dewatering. Through reasonable adjustment of operating parameters and equipment parameters, high solid content and solid recovery of mud cake can be achieved. In the future development, we should continue to study and improve the technology of horizontal spiral centrifuge to improve its treatment efficiency and application scope, and combine other treatment methods and equipment to meet different sludge treatment needs and contribute to environmental protection and sustainable development.
