Municipal sludge drying equipment to solve the problem of sludge treatment

With the rapid development of economy, the output of sludge is increasing day by day. The problem of sludge treatment and disposal is concerned by all walks of life. The sludge can be used as fuel, used for agriculture and incineration, and can be made into various building materials, which can solve the problem of sludge treatment.

Sludge drying equipment is a kind of energy-saving, environmental protection, high production efficiency and environmental protection equipment. The equipment can continuously dry the wet sludge with moisture content of about 80% to the dry sludge of about 10%, which greatly reduces the volume and weight of sludge, makes the sludge sanitary and reduces the burden of sludge subsequent treatment.

The municipal sludge drying equipment adopts the drying technology of "rotary harrow three-cylinder multiple-loop" of ZJN company. The whole drying process is divided into three parts. The sludge and hot air first enter the inner cylinder of the drying equipment. Under the action of the inner cylinder crushing device, the sludge is continuously dispersed and separated to form a uniform material curtain, which increases the contact area between the sludge and the hot air, accelerates the evaporation of the surface moisture of the sludge, and makes the sludge change from high humidity to non humidity and high viscosity to non viscosity. After that, it is fed into the central cylinder under the action of a special plate. In the middle drum, the counter current and vortex drying method is adopted to make the sludge go against the hot air, and further dry the sludge, and then the sludge is sent into the outer cylinder under the action of a special material plate. The outer cylinder adopts the mode of alternating current and reciprocating drying, so that the wet sludge can be reciprocating and slow moving, and the sludge meeting the drying requirements should be discharged from the equipment outlet automatically. The whole drying production line is automatically controlled with high drying efficiency and good product quality.

The characteristics of the whole sludge drying equipment production line are as follows:

1. Strong drying capacity

The moisture content of sludge can be reduced to about 10%, and the reduction can be more than 90%.

2. Low energy consumption of equipment

The equipment adopts heat energy distribution system, which can automatically adjust the drying temperature, air volume and wind speed according to the moisture content of sludge in different stages, thus greatly saving energy consumption. At the same time, with the equipment sealed tightly and good insulation function, can effectively reduce the loss of heat.

3. The equipment has stable performance and high safety factor

The equipment can run continuously for a long time without any flammable and explosive phenomena.

4. Wide application range

It can be used for drying various kinds of sludge, such as municipal sludge, electroplating sludge, pharmaceutical sludge, papermaking sludge, printing and dyeing sludge, textile sludge, chemical sludge, oily sludge, leather sludge, alkali sludge, coal sludge, etc.

5. High degree of intelligence

The equipment adopts automatic control mode, which is easy to operate and does not need to invest too much manpower.
