What is the function of rotary drum sludge dryer in sludge disposal

Rotary drum sludge dryer is a common type of drying equipment. According to the structure, it can be divided into single drum dryer, three drum dryer and so on. Among them, the three barrel drying equipment is the standard equipment for many sludge disposal enterprises. Its emergence has solved the problem of high humidity and high viscosity sludge drying well. With reliable performance and rapid drying effect, it has won the support of many users. For the whole drying production line, a qualified sludge dryer is very important and an important part of sludge disposal. Next, the ZJN editor will specifically introduces its function.

With the development of industry and the increasing demand of people's life, electroplating, textile, leather, metal treatment and other industries will produce a large number of sludge in the normal production process. These sludge contains a variety of chemicals, and its properties are not stable. Long term accumulation in the soil and water source will cause serious harm to the environment. Therefore, sludge disposal has become the primary consideration of many enterprises. The first consideration of sludge disposal is "reduction and innocuity". The rotary drum sludge dryer is developed and produced for this purpose.

The structure of the traditional single drum dryer is simple. Its main body is a single-layer cylinder drum. The materials and hot air enter from one end and exit from the other end. Due to the single-stage operation of the equipment, the process is relatively simple, and the materials are prone to unevenness of drying and moisture at the end, etc., which cannot meet the drying operation of high humidity and high viscosity materials. Therefore, on the basis of single drum rotary sludge dryer, the ZJN environmental protection equipment draws lessons from a variety of drying technologies at home and abroad. After many years, it has developed a series of high humidity and high viscosity drying equipment with "three sleeves" structure, which is only one third of the length of single drum equipment, greatly improving the drying efficiency and good heat preservation. The energy and sealing performance reduce the loss of heat energy. The material is divided into three drying stages in the whole drying process. Through deep drying and layer by layer dehydration, a better drying effect is achieved. It is the choice of many famous enterprises at present.
