Rotary Rake Triple Stage Muti-loop Dryer for industrial sludge

At present, the disposal of industrial hazardous waste sludge has gradually become the focus of attention at home and abroad. Concentration, dehydration, stabilization, and desiccation of sludge are the necessary means by which sludge to be disposed of. It is also one of the most thorny issues for companies who produce hazardous waste and companies to treat hazardous waste.

In the sludge drying process, mechanical dewatering can only remove free water and part of the interstitial water present between the sludge particles; the capillary water, although it has strong binding force with the sludge particles, it can also be removed by higher-mechanical-capacity force. While, since the amount of internal bound water is related to the proportion of microbial cells in the sludge, it is impossible to use mechanical methods to remove them.

At present, high-temperature heating methods are generally used to remove them from sludge. But the traditional high-temperature heating dehydration process has the problems of high processing cost, large exhaust gas emission, large amount of cooling water, secondary pollution of odor and dust, and even the risk of dust explosion. The investment and operating costs of this sludge drying method are generally high, and there are many drawbacks in actual operation.

 

However, Rotary Rake Triple Stage Muti-loop Dryer for industrial sludge, which ZJN owned the fully independent intellectual property, has the features of low energy consumption, no secondary pollution, low operating cost, high degree of automation, and safe and stable operation. The maximum daily processing capacity of a single set of equipment can reach to 1,000 tons, and the drying efficiency and quality are impeccable.

In view of the already installed and running equipment, the advantages of energy saving and environmental protection are obvious. Matched with the patented drying process of "using boiler flue gas waste heat", ZJN Rotary Rake Triple Stage Muti-loop Dryer for industrial sludge drying cost is much lower than other treatment methods.

Particularly commendable is that it uses "low-temperature high air volume" drying technology, air direction, volume and temperature is adjustable and controllable. The unique "rotary rake" "turning rake" device can fully disperse and break the material and gradually form small particles and material curtain, so that the material and the hot air fully in contact and orderly churning move. Thereby effectively avoiding anaerobic gas, the entire process does not produce toxic gases such as dioxin.

With this process, the moisture of finished sludge can be reduced to below 30%, and in irregular particle state, and the physical and chemical properties of the material itself will not be changed. According to different material characteristics, the finished sludge can be used for metal extraction, fuel, and organic fertilizers, as well as raw materials for building.

So it is an advantage project with huge market potential.
