High-Efficiency Paper Pulp Dryer for Optimal Production Output

Product Description

Product Description

The paper pulp residue dryer is a drying equipment specifically designed for pulp residues generated in the paper-making industry (such as residual fiber residues from pulping processes, filter residues from waste paper treatment, etc.). Its core function is to remove excess moisture from pulp residues through thermal energy, converting wet residues with high initial moisture content (usually 50%-85%) into dry materials with controllable moisture content (generally reduced to below 10%), thereby achieving volume reduction, weight reduction, and resource recovery of solid waste. The equipment consists of a feeding device, a drying host (mostly drum-type), a heat source system (such as a gas furnace, biomass furnace, etc.), an exhaust gas purification system, a discharging mechanism, and an intelligent control system. It can flexibly adjust operating parameters according to the fiber characteristics, viscosity, and processing capacity of pulp residues to adapt to drying needs in different scenarios.

Working Principle

The paper pulp residue dryer realizes drying through the synergy of "hot air convection + mechanical dispersion", with the specific process as follows:

1. Feeding and pre-processing: Wet pulp residues are conveyed into the drying drum via a screw conveyor. Special lifting plates or dispersing components inside the drum disperse and crush agglomerated residues, preventing caking and increasing the contact area between materials and the heat medium.

2. Heat exchange drying: High-temperature hot air (120-300℃) generated by the heat source system flows countercurrently (occasionally cocurrently) with the dispersed pulp residues in the drum. Through convective heat exchange between hot air and the material surface, free water and part of the bound water in the pulp residues are quickly evaporated.

3. Separation and purification: The dried materials are discharged from the outlet as the drum rotates. The dusty, damp, and hot exhaust gas generated during the process is treated by purification devices such as cyclone separators and bag filters to remove dust before reaching emission standards, avoiding secondary pollution.

Product Features

1. Strong targeting: Specifically designed for the fibrous and highly viscous characteristics of pulp residues, the dispersing components can effectively break up material agglomeration and solve the problem of wall sticking in traditional drying equipment.

2. High efficiency and energy saving: Adopting an optimized design of hot air flow field, the hot air utilization rate reaches over 80%; some models are equipped with waste heat recovery devices, which reuse waste heat from exhaust gas to heat fresh air, reducing energy consumption by about 30%.

3. High controllability: Real-time adjustment of drum speed, hot air temperature, and feeding amount through a PLC intelligent control system, with precise control of the moisture content of discharged materials (error ≤±2%).

4. Stable operation: The inner wall of the drum is coated with anti-sticking coating and made of wear-resistant materials, reducing material adhesion and equipment wear, with a long continuous operation cycle (capable of 24-hour uninterrupted production).

5. Environmental compliance: Equipped with a fully enclosed system and multi-stage dust removal devices, the dust emission concentration is ≤30mg/m³, meeting national industrial exhaust gas emission standards and satisfying environmental approval requirements.

Application

1. Solid waste treatment in paper mills: Handling pulp residues generated in the production of wood pulp, straw pulp, and waste paper pulp. After drying, they can be used as boiler fuel (replacing coal) or recycled fiber raw materials for low-grade paper production.

2. Biomass energy processing: Mixing dried pulp residues with straw, wood chips, etc., and pressing them into biomass pellet fuel for power generation or industrial heating.

3. Organic fertilizer production: Dried pulp residues are mixed and fermented with livestock and poultry manure to produce high-carbon organic fertilizers for agricultural planting.

4. Environmental engineering: Assisting solid waste treatment centers in handling mixed waste containing pulp components, reducing transportation and landfilling costs, and promoting the resource recycling of solid waste.
