Sludge dryer machine/ rotary sludge dryer

Sludge dryer machine, as the name suggests drying sludge equipment, it is widely used in urban sludge drying. Sludge drying treatment, so that sludge farming, as a fuel use, burning and even to reduce the landfill site and other treatment methods possible. With the strengthening of national economic strength, the improvement of national environmental awareness, the rapid development of urban sewage treatment industry, the increasing production of municipal sludge, sludge disposal and development and utilization of the growing concern for the people.

The sludge dryer is a kind of sludge with special characteristics such as high moisture content, high viscosity, high water holding capacity and low calorific value. It is specially designed for sludge drying equipment. It is done in the internal structure of the dryer special design, not only improve the thermal efficiency, but also effectively avoid the sludge in the dryer inside the sticky and too dry phenomenon. The new sludge dryer features are as follows:

1. Efficient energy-saving. Sludge dryer uses a new type of transmission, compared to the general sludge dryer, saving nearly 20% of coal for customers to save costs, is to create value for our customers.
2. Green environmental protection. Sludge dryer using multi-stage purification dust removal equipment, and higher than the national requirements of environmental standards, reduce equipment for environmental pollution.
Sludge dryer composition:
 Sludge dryer mainly by the induced draft fan, scrambling device, belt feeder, feeder, rotary drum, heat source, belt feeder, unloader and distribution cabinet composition. Therefore, single-channel sludge dryer working area, including the discharge area, tilt the plate area, cleaning area, the composition of the material area.
First, the guide area, wet sludge into this area and high temperature hot air contact with the rapid evaporation of water, the material in the big corner of the copy board copy, the shape will not be bonded into the next work area;
Second, the discharge area, drums in this area does not copy board, the material rolling in this area to the discharge port to complete the entire drying process;
Third, the clean area, wet sludge in this area was copied from the form of copy the formation of material curtain state, the material is easy to form when the phenomenon of adhesive drum wall, in this area because the device design has a cleaning device, cleaning device will be very reasonable cleaning. The inner wall of the adhesive material, in this process, the cleaning device for the material ball
Agglomeration also from the crushing effect, thereby increasing the heat exchange area, improve the drying rate;
Fourth, the tilt plate area, wet sludge in this area has been a low moisture loose state, the material in this area has no bonding phenomenon, after the heat exchange of materials to meet the required water state, into the final discharge area.
In general, the sludge dryer can be widely used in activated sludge drying, sewage sludge drying, petrochemical sludge drying, papermaking sludge drying, printing and dyeing sludge drying, tannery sludge drying, electroplating sludge drying, Municipal sludge drying, bio-fermentation sludge and other sludge and a variety of bad dregs and other high-humidity materials dry.
