stay Dewatering of papermaking sludge In the process, common mechanical equipment includes:

1. Belt press: the belt press uses high-pressure belt to dewater and press the sludge. The utility model has the advantages of large processing capacity and is suitable for high humidity sludge; The disadvantage is that the equipment and maintenance costs are high, and the requirements for fiber and particle contained in sludge are high.

2. Spiral thickener: The spiral thickener concentrates the sludge through the screw propeller to separate the water in it. The advantages are simple structure, small space occupation and high processing capacity; The disadvantage is that the sludge concentration is not complete, and further dewatering is required for subsequent treatment.

three Centrifugal dehydrator : Centrifugal dehydrator, such as Horizontal screw centrifuge Or scraper Centrifuge The sludge is separated into solid and liquid by centrifugal force. The advantages are good separation effect and low moisture content of solid particles; The disadvantage is that the equipment and maintenance costs are high, and the slag outlet is easy to be blocked in some cases.

4. Paddle vacuum filter: the paddle vacuum filter uses vacuum suction to filter and dewater the sludge. The utility model has the advantages that the high humidity sludge can be treated and the filtering effect is good; The disadvantage is that the equipment is complex in structure and operation.

The advantages and disadvantages of each type of equipment are different in different aspects, and the specific application needs to comprehensively consider the sludge characteristics, treatment requirements, equipment investment, operating costs and other factors to select the appropriate Dehydration equipment 。 At the same time, the operation and maintenance of equipment are also key factors to ensure dehydration effect and equipment performance.
