Sludge drying equipment solves sludge treatment problems

At present, sludge treatment and disposal in China is more difficult than sewage treatment. Whether it is disposal, landfill or land use, it will be limited to landfill space and land use. In addition, sludge contains organic matters, various pathogens and other harmful substances, which is easy to form secondary pollution sources, leading to environmental pollution and harm to human health. Sludge drying can effectively reduce the water content and the volume of sludge. The dried sludge is odorless, harmless and stable. At the same time, the dried sludge is widely used. It can not only be used as building materials or bricks, but also as energy.

The way of sludge drying is divided into direct drying and indirect drying. Direct drying is to make hot air directly contact with sludge, so as to achieve the purpose of drying. The advantages of this drying method are high heat utilization rate and drying efficiency, but the disadvantage is that the hot air is easily polluted by sludge due to the direct contact between hot air and sludge, so tail gas and waste gas can be discharged only through special treatment. Indirect drying is that the hot air does not directly contact the sludge, it is through the surface of heat capacity to transfer heat and contact with the sludge, so as to achieve sludge drying. The advantage of this drying method is that the exhaust gas after drying is not affected by sludge, and its disadvantage is that the utilization rate of heat energy is poor and the drying efficiency is not high. So the enterprise should choose the drying method acoording to the situation of sludge.

The Jiaozuo ZJN sludge drying equipment adopts the "rotary harrow three cylinders multiple-loop" process, whose air volume and temperature can be adjusted according to the moisture content of materials. The new design process of "high + high + high", "medium = medium = medium" and "low - low - low" is used in the equipment, which makes the air volume and temperature always compatible, so that the material is always in the ideal drying environment. The whole system complements and interacts with each other, forming a chain system.

Advantages of ZJN sludge drying equipment:

1. Equipment customization

According to the demand parameters provided by customers, carry out by the R & D and manufacturing;

2. Equipment operation

Automatic control mode, convenient and stable for continuous operation and reduces manual labor;

3. Production capacity

Large processing capacity, wide application of materials, low drying cost and adjustable drying quality;

4. Installation of equipment

Easy to install and covers a small area. It can be indoors and outdoors.

5. Impact on the environment

After drying, the waste gas is sent to the independent bag type dedusting equipment for treatment, and reaches the national emission standard through filtration settlement, which has little impact on the environment.
