Horizontal screw centrifuge It is one of the common equipment for treating cellulose wastewater. Cellulose wastewater usually refers to the wastewater containing cellulose fibers, suspended solids, particles, etc., such as the wastewater generated by pulp and paper industry. Recumbent snail Centrifuge Solid particles in cellulose wastewater can be separated and dewatered by rotating screw propeller and centrifugal force.
In cellulose wastewater treatment, the main function of horizontal screw centrifuge is to dewater solid wastes and separate solid and liquid phases. The solid particles are deposited on the wall of the shielding cylinder to form a solid layer, and the water is discharged from the drum of the centrifuge. The solid moisture content after dehydration is reduced, which is convenient for subsequent treatment and disposal.
The advantages of horizontal spiral centrifuge in cellulose wastewater treatment include compact structure, large treatment capacity, good dehydration effect, etc. However, it is necessary to comprehensively select the appropriate type and specification of horizontal spiral centrifuge according to the sewage characteristics, treatment requirements, equipment performance and other factors to ensure the optimal dewatering effect.
In addition, some special cellulose wastewater (such as high concentration, small particle size, etc.) may need to be further treated with other equipment or process steps to improve the treatment effect. In practical application, it is recommended to consult and discuss with the equipment supplier or process engineer in detail to determine the most suitable cellulose Sewage treatment equipment Programme.
In addition to the decanter centrifuge, there are other equipment that can be used to treat cellulose wastewater. Here are some common devices:
1. Belt press: The belt press uses high-pressure belt to press and dewater the sludge. It is applicable to cellulose wastewater with high humidity and high cellulose content, and can effectively squeeze water out of sludge to achieve dehydration and concentration.
2. Belt filter: the belt filter filters the sludge through the filter cloth or filter screen to filter out the solid particles in the sludge. This equipment is applicable to cellulose with fine particles Sludge treatment , with good Solid-liquid separation effect.
3. High efficiency mechanical press: The high efficiency mechanical press presses cellulose sludge through a rotating drum or filter screen. It has high treatment capacity and dehydration effect, and is suitable for the treatment of cellulose sludge with high concentration and viscosity.
The above equipment can effectively treat the solid-liquid separation and reduce the solid moisture content when treating cellulose wastewater, so as to facilitate subsequent treatment and disposal.
It is necessary to select appropriate equipment and process combination according to specific cellulose wastewater characteristics, treatment requirements, equipment performance and other factors to meet the needs of cellulose wastewater treatment to the greatest extent. Consulting professional equipment suppliers or process engineers is an important step to ensure the selection of appropriate equipment and the implementation of appropriate processes.
