Why revamp paper and pulp industrial filter

Paper and pulp filtration equipment is mainly used for pulp concentration and recovery of the fiber from whitewater in paper mills. Because the working temperature of the equipment is high, the reliability of the equipment operation will degrade after a long-term operation, which requires frequent maintenance by the workers. But it is difficult for the operator to replace the mesh screens, and the cost of replacing the mesh screens is high. Hengtai revamp for the paper and pulp industrial filter can improve equipment performance, reduce equipment maintenance costs, and reduce the operator's operating intensity.

Revamps and the effects after revamps
Revamps The effects after revamps
1. Sectors were modified into non-mesh screen sectors Filtration area increased by more than 15%. The SS value of clear filtrate (suspended solid in water) reached 50 ppm, which creates good economic benefits for customers.
2. Pulp stripping system revamp. Common spray nozzles were modified into self-cleaning spray nozzles The spray nozzles blocking are reduced, which improves the efficiency of pulp stripping.
3. Cleaning System was modified by adding the brush. The spray nozzles blocking are reduced, which improves the efficiency of cleaning system, and it is not easy to plug the mesh screen, prolonging the service life of the mesh screen.
4. Revamp of the distribution valve wear-resistant sheet material by applying ultra-high polymer wear-resistant sheet material. Strong acid resistance, strong alkali resistance, high temperature resistance and good wear resistance.
5. The rotary disc filter sector seal is made of special rubber and non-ferrous metal. The sector seal is not easy to deform, and displays good resilience, perfect sealing effect, acid resistance, alkali resistance, and high temperature resistance.
6. Optimization of the rotary disc filters automatic control system. The pulp concentration can be up to 12% and the vacuum degree is stable.
7. Optimization of the rotary disc filters production process. Equipment capacity was improved, the loss of fiber was reduced, and the cost of per ton of paper was also reduced.
Our main products are poly disc filters, and our company also provides the solutions according to the actual requirements of customer.
