Why the sludge drying equipment uses three return process to treat materials

Drum sludge drying equipment is very common in drying market. According to the different structure types, it can be divided into single drum sludge drying equipment and three-way sludge drying equipment. Especially in the process of drying high humidity and high viscosity sludge, three-way sludge drying equipment is often used. So why does the sludge drying equipment use three-way sludge drying equipment? What are the characteristics and advantages of the three-way sludge drying equipment.

1. Special structure of three-way sludge drying equipment

Compared with the traditional single drum sludge drying equipment, the main body of the three-way sludge drying equipment is nested by three-layer rollers, which greatly extends the travel of material and hot air drying, and effectively solves the problem of the large area of the single drum equipment. The reduction of volume makes the heat loss less when the three-way sludge drying equipment is handling materials, which not only facilitates installation and disassembly, but also saves a large part of the site capital investment cost for customers.

2. The three-way sludge drying equipment is faster in handling materials

Although the volume is smaller, the three-way sludge drying equipment is faster to treat the material. Because the cylinder is equipped with a breaking device, and different angle and spacing lifting plate and guide plate device, large pieces of materials will be broken after entering the cylinder, and they will be lifted and scattered continuously, and the contact area between materials and hot air will be increased, so as to dry the high humidity and high viscosity sludge more quickly.

3. Better insulation performance of three-way sludge drying equipment

Compared with single tube equipment, due to the special three tube structure, the inner and middle tubes are surrounded by the outer tubes, thus forming a self insulation system. The heat emitted from the inner and middle cylinder surfaces is fully utilized to enhance the heat exchange effect, while the outer tube is at the low temperature end of the thermal air flow, so the heat dissipation area and heat loss of the cylinder will be greatly reduced It's too low.

4. The utilization of heat energy is higher when the three-way sludge drying equipment is used to treat materials

When the three-way sludge drying equipment is used to treat materials, it can make full use of heat energy, reduce heat loss, increase heat exchange area, make the moisture in sludge evaporate rapidly, thus effectively improve the utilization of heat energy, reduce energy consumption and save the operation cost of equipment. At the same time, the pollution of waste heat to the environment is further reduced. The waste gas treatment equipment configured in the drying production line will clean the dust containing waste gas and then discharge it into the atmosphere, which can realize the functions of energy saving and emission reduction and low-carbon environmental protection. Therefore, more and more users have chosen three-way sludge drying equipment to deal with high humidity, high viscosity and large quantities of material drying.
