What are the characteristics of the technological process of three drum sludge drying equipment

The three cylinder sludge drying equipment is a common sludge dewatering equipment at present. Its main body is nested by three concentric rollers with different diameters. The scientific and reasonable equipment structure greatly increases the drying speed and output of sludge, and can effectively deal with all kinds of industrial sludge, textile sludge, papermaking sludge, steel mill sludge, metal sludge, river sludge, sewer sludge, etc Drying of wet and high viscosity materials. With the continuous development of drying technology in recent years, three cylinder sludge drying equipment is loved by more and more users.

Technological process of three drum sludge drying equipment

During the operation of the equipment, the material is sent into the cylinder from the feeding end by the feeding device, and the high temperature hot air provided by the heating equipment also enters the cylinder through the pipe. The material in the cylinder is first broken into bulk by the dispersing device, which increases the contact area between the material surface and the hot air. Then, under the action of the material lifting device, the material in the cylinder is continuously lifted and scattered, and a uniform material curtain is formed on the cross section of the cylinder. At this time, the full contact (direct contact or indirect contact) of hot air and materials greatly speeds up the drying speed and improves the utilization rate of heat energy.

The movement of materials and hot air from the inner cylinder to the outer cylinder makes full use of the heat energy emitted from the inner cylinder and reduces the heat loss, which not only increases the thermal insulation performance of the cylinder, but also reduces the energy consumption of the equipment operation. After three stages of drying, the moisture in the material meets the requirements of the finished product, and then it is sent out by the discharge end.

How to reduce the drying time of three cylinder sludge drying equipment

1. Influence of equipment length on drying time

In general, the longer the length of the equipment, the more materials it can handle at the same time, the greater the capacity of the equipment, but it does not mean that the length of the equipment can be infinitely extended. Too long length not only takes up a large area, but also has a great loss of heat energy in the drying process, which greatly increases the operating cost of the equipment.

2. Influence of equipment speed on drying time

The rotation speed of the drum determines the drying time of the sludge drying equipment to a certain extent. The higher the rotation speed is, the shorter the material stays in the drum, and the corresponding drying time will be reduced. Therefore, on the premise of ensuring that the materials meet the drying requirements, properly increasing the rotation speed can effectively improve the work efficiency.
