What is the working principle of municipal sludge drying equipment

Municipal sludge is a thorny pollution problem in urban development. It is not only high cost of manual treatment, but also difficult to dispose of due to its high humidity and high viscosity. Municipal sludge drying equipment uses the working principle of high temperature drying to reduce and recycle sludge, which is a sharp tool to solve the problem of sludge pollution. At present, investment in municipal sludge drying equipment has become a good project to protect the ecological environment, obtain economic benefits, and respond to the national energy conservation and emission reduction policy.

Working principle of municipal sludge drying equipment

The sludge is fed into the dryer cylinder by the feeding device, and with the rotation of the cylinder, the "rotary rake flying" crushing device in the cylinder continuously disperses and breaks the sludge into a boiling state. Under the action of the scientifically designed guide plate and lifting plate, the sludge gradually spreads into a uniform material curtain and fills the whole drying space. At this time, the high-temperature hot air provided by the heating equipment passes through and evaporates most of the water. At the same time, the material carried by the wing plate is lifted, scattered and repeated for many times, which greatly increases the contact area between the material and the hot air, fully carries out heat exchange, and further dries the sludge. The built-in cleaning device cleans the materials adhered on the inner wall and breaks the agglomerated sludge at the same time. After drying, the sludge becomes loose material with low moisture content, which is discharged from the outlet and the drying process is completed.

In the whole drying process, due to the high humidity, high viscosity and large output demand of municipal sludge drying equipment, the key to the working principle of municipal sludge drying equipment is the design of anti sticking. Generally speaking, the faster the drying speed of sludge drying equipment is, the easier it is to stick. The new municipal sludge drying equipment researched and developed by ZJN company makes the sludge quickly "move" in the cylinder. The combined lifting device is adopted, which greatly expands the application scope of single channel drying machine. It can not only dry all kinds of sludge, but also dry various high humidity and high viscosity materials.

In the high humidity and high viscosity municipal sludge drying series products, the “Rotary harrow three cylinders multiple-loop municipal sludge drying equipment developed by ZJN company is an energy-saving and environmental protection product improved on the basis of single drum dryer. The ZJN brand has been operating for more than 30 years. It has been committed to the technology research and development of dryer, equipment production and project construction. Its market influence is self-evident. In recent years, the export business of the enterprise has developed in full swing, and the performance is gratifying. It is worth the customers to choose decisively.
