Operation mechanism of industrial waste sludge dryer

According to incomplete statistics, up to now, about 10 million tons of industrial waste sludge have been produced in China every year. Due to the problems of sludge treatment not up to the standard and insufficient investment in sludge treatment equipment, the problem of large amount of industrial sludge accumulation can not be solved in time. With the promulgation and implementation of the "ten water regulations", the relevant practitioners pay more and more attention to how to meet the requirements of harmless, reduced, stable and resource-based treatment and disposal. In response to the market demand, the real energy-saving and environmental protection equipment has developed a series of "rotary harrow three cylinders multiple-loop" series of high humidity and high viscosity large-scale industrial waste sludge drying machine, aiming at the characteristics of large-scale industrial sludge production, high water content and easy adhesion, which solves the drying problem of industrial sludge very well. How does it operate?

The moisture content of the wet sludge dewatered by filter press or centrifuge is still very high, and the purpose of "volume reduction and reduction" has not been completed. After the wet sludge is sent into the dryer barrel by the feeding device, the wet sludge is quickly dispersed into fine particles under the action of the "rotary rake crushing" device built in the drum, and it is constantly stirred by the combined "lifting" device with uniform distribution in the cylinder It can greatly increase the contact area between sludge particles and hot air, and accelerate the heat and mass transfer effect. The drying process is divided into three stages: forward flow drying, counter current drying and multi loop reciprocating drying. It can dry all kinds of high humidity and high viscosity materials. The main machine is equipped with automatic control system, which is very convenient to operate. The materials dried by the industrial waste sludge dryer will be discharged from the discharge port at the other end, and can be transported or stored after packaging.

At present, the new dryers in the market pay great attention to environmental protection. The ZJN drying production line is mainly composed of industrial waste sludge drying machine, with heat supply system, feeding system, waste gas treatment equipment and other devices. The overall economic benefit is good, the environmental protection is strong, and the thermal efficiency is high. The production line adopts multi-stage purification and dust removal equipment, which can meet and exceed the national environmental protection standards and reduce the environmental pollution.
