Horizontal screw centrifuge Is a common Solid liquid separation equipment It is widely used in the sewage treatment process of ceramic industry. In the ceramic production process, a large amount of sewage will be produced, which contains suspended solid particles, such as ceramic powder, pigments and various additives. These suspended solids need to be removed through the separation process, so as to facilitate the standard discharge of wastewater and the recovery and utilization of resources.
Recumbent snail Centrifuge Its working principle is to use the high speed rotating drum to generate strong centrifugal force, and the solid particles in the sludge are thrown onto the inner wall of the drum due to the high density, forming a solid ring layer; The lighter water forms a liquid ring layer due to the small centrifugal force. The sludge is pushed to the outlet of the small end of the drum for discharge through the differential movement of the rotary and spiral, thus realizing Solid-liquid separation 。
stay Ceramic sewage treatment The main applications of horizontal screw centrifuge are as follows:
1. Sludge concentration: the suspended solids content in ceramic industrial wastewater is high, and the horizontal spiral centrifuge can concentrate the sludge to reduce the load of the subsequent treatment unit.
2. Sludge dewatering: sludge particles are flocculated by adding flocculants to accelerate the separation of sludge and water, so as to achieve sludge dewatering and improve the solid content of sludge.
3. Resource recovery: During the separation process, the horizontal spiral centrifuge can not only remove the water in the sludge, but also recover some substances, such as ceramic powder, which reduces the waste of resources.
4. Environmental protection: effectively treat suspended solids in ceramic wastewater, reduce environmental pollution, and comply with national environmental protection regulations.
When selecting horizontal screw centrifuge, appropriate models and parameters shall be determined according to the specific characteristics of ceramic wastewater (such as solid content, solid particle size distribution, sludge viscosity, etc.) and treatment requirements (such as treatment capacity, solid recovery rate, solid content, etc.). At the same time, the operation cost, maintenance convenience and compliance with local environmental protection regulations of the equipment shall also be considered.
In a word, the horizontal spiral centrifuge plays a vital role in ceramic wastewater treatment. It not only helps to improve the treatment efficiency of ceramic wastewater and reduce the treatment cost, but also plays an important role in promoting the green development and environmental protection of the ceramic industry.
