Solid waste dryer type introduction: single cylinder and three cylinder

Single cylinder solid waste dryer

Single cylinder solid waste dryer is a common drying equipment, which can be used for dehydration and drying of various sludge and dregs. The so-called single cylinder solid waste dryer is to use a circular cylinder, and the cylinder itself has a certain inclination, which can facilitate the flow of sludge in the cylinder.

Working process: wet sludge enters into the cylinder from the inlet, while hot air flows into the cylinder from the outlet. The two are in contact with each other inside the cylinder. Through forward or reverse contact, the moisture in the wet material can be evaporated quickly, so as to achieve the purpose of sludge drying.

Its disadvantages: when the wet mud is dehydrated and dried, the thermal efficiency is low, the thermal insulation performance of the cylinder is poor, which will cause a lot of waste of heat; it covers a large area, and the treatment capacity is not as large as the three cylinder solid waste dryer.

Three drum solid waste dryer

Three cylinder solid waste dryer is a new type of drying device in recent years, which is smaller than single cylinder dryer. Three cylinder sleeves with different diameters are embedded together. It reduces the floor area, increases the internal storage space, has large processing capacity and low energy consumption.

Working process: the structure of three cylinder solid waste dryer can divide the whole drying process into three parts. First of all, the sludge enters into the inner cylinder of the equipment cylinder. Under the action of the dispersing device installed in the inner cylinder and the guiding material system device, the sludge is quickly separated and stirred to accelerate the contact between the sludge and the hot air and quickly evaporate the water on the surface of the sludge. Secondly, it is fed into the middle drum under the action of the special material plate. The middle drum adopts countercurrent and vortex drying to further evaporate the water in the sludge. Thirdly, it is sent into the outer cylinder under the action of special material plate. The outer cylinder adopts AC plus reciprocating drying, so that under the action of air volume and special material plate, the wet can do reciprocating and slow running, the dry can go first and fast running, and the sludge can be discharged automatically after reaching the drying requirements.

In a word, both single drum solid waste dryer and three drum solid waste dryer have their own advantages and disadvantages. Users should choose suitable dryer equipment according to their own actual production requirements when purchasing equipment products.
