Pulp sludge is the waste paper pulp produced in the papermaking process of paper mills, which is the product after impurity removal, soaking and filtration. The composition of pulp sludge is relatively complex, containing a variety of plant fibers and a small amount of animal fibers, mineral fibers and synthetic fibers, with a high content of organic components. In addition, it also contains dust, ink, adhesive substances and other debris. After the waste paper pulp sludge is dried in the pulp sludge dryer, the secondary fiber can be recycled and reused, which not only saves original resources and energy, but also reduces environmental pollution and also brings huge economic benefits to the enterprise. interests and social benefits.

The production line of pulp sludge drying equipment is composed of heating equipment, hopper, feeding device, pulp dryer main body, discharging device, dust removal device, induced draft fan, power distribution cabinet and other parts.

Working principle of pulp sludge: The pulp dryer adopts a three-layer roller drying structure. The inner cylinder adopts downstream drying, which can evaporate most of the water; the middle cylinder adopts counter-current drying, which can continuously turn the material so that it is fully exposed to the hot air, so that the material is heated evenly and further evaporates the moisture in the sludge; the outer cylinder The body adopts AC plus reciprocating drying. Under the action of air volume and special material plates, the sludge meets the drying requirements and can automatically discharge pulp, thereby completing the drying operation of papermaking sludge.

Advantages and features of pulp sludge dryer

1. The pulp sludge dryer has reasonable price, large processing capacity, high production efficiency and low cost.

2. The production line is reasonably designed and can be reasonably assembled according to the user's actual land area, and the land area can be used reasonably and effectively.

3. The entire production line adopts automated control, which is simple and convenient to operate, and the equipment performance is stable and can run continuously for production. The equipment failure rate is low and the maintenance cost is low.

4. The pulp sludge drying equipment is tightly sealed as a whole, which can not only effectively reduce the heat loss of the cylinder, but also reduce the spillage of flue gas and dust, effectively ensuring a clean and tidy production environment.

5. The moisture content and particle shape of the dried pulp can be adjusted according to actual needs, which greatly facilitates subsequent resource reuse.
