Production efficiency of sludge drying equipment and sludge reuse

With the rapid development of electroplating, petrochemical, steel, textile, paper, leather, pharmaceutical, urban, municipal and other industries, a large number of industrial sludge and municipal sludge are produced in the production process, which will not only restrict the economic development of enterprises, but also seriously pollute the environment. Due to the high moisture content and high viscosity of these sludge, when using the traditional sludge drying equipment to dry the sludge, the production efficiency is low, and it is easy to cause the material to stick or stick to the wall, resulting in poor quality of the dried sludge. Therefore, it is necessary to use high humidity and high viscosity drying equipment for high humidity and high viscosity sludge.

The high humidity and high viscosity sludge drying equipment is used to treat the sludge. The sludge is sent into the cylinder through the conveying device, and then the sludge is continuously dispersed, broken, stirred and lifted under the action of the internal rotary rake scattering device and the lifting material system, so as to increase the contact area between the sludge and the hot air, accelerate the evaporation of the internal moisture in the sludge, and avoid the mutual adhesion or wall sticking of the sludge The utilization rate of heat energy and production efficiency can be improved, and the quality of sludge after drying can be guaranteed.

Characteristics of sludge drying equipment: the equipment adopts automatic control, simple and convenient operation, and does not need too much manpower; the equipment has stable performance, can operate for a long time and has low failure rate; it has large processing capacity and low production cost; the equipment is tightly sealed, which can effectively reduce the heat loss, and reduce the leakage of flue gas and dust inside the equipment, so as to ensure the clean and tidy production environment; The equipment uses a wide range of heat sources, including coal, natural gas, gas, steam, boiler flue gas waste heat, diesel, electricity, biomass particles, etc.

Reuse of dried sludge:

The dried sludge: 1. It can be sent to the cement plant to mix the cement and clinker to make cement; 2. It can be mixed with raw coal to reduce the energy consumption of boiler coal and improve economic benefits; 3. It can be sent to the brick factory to replace clay and coal powder to make light bricks; 4. It can be used as slow release fertilizer to increase the output of crops; 5. It can be used as chemical raw materials for production; 3; 6. It can be used to improve soil water retention and corrosion resistance. 7. Sanitary landfill.
