Product Introduction
   The sludge drying system is suitable for drying all kinds of sludge with high viscosity. It can dehydrate the wet sludge with 85% water content to 40% and then dry it into dry powder with water content below 10%. The sludge drying system operates under negative pressure and is equipped with an enhanced heat transfer device for direct heat transfer. Material drying moisture control is convenient, operation flexibility is large, and the product flow rate is allowed to have a large fluctuation range. The system has few high-temperature mechanical equipment, simple structure, easy cleaning, low failure rate, continuous operation and low maintenance cost. The sludge dryer system is widely used in activated sludge drying, sewage sludge drying, petrochemical sludge drying, paper sludge drying, printing and dyeing sludge drying, leather sludge drying, electroplating sludge drying, municipal sludge drying , Drying of various sludges such as biological fermentation bacteria residues and various high-humidity materials such as slags.

The effective method of sewage treatment is to dehydrate the sewage and then dry the sludge. The volume of the dried sludge can be reduced by 4 to 5 times. The product is odorless and pathogen-free. It can be used as fertilizer, soil amendment, and substitute It has a wide range of uses such as energy. The sludge dryer system is widely used in drying all kinds of sludge, such as electroplating sludge, tannery sludge, chemical sludge, oil field sludge, city

Municipal sewage treatment plant sludge, activated sludge, sewage sludge, petrochemical sludge, papermaking sludge, printing and dyeing sludge, biological fermentation sludge and other high-humidity materials and various high-humidity materials are dried.

working principle
The drying system includes: heat source, drying equipment, conveying equipment, dust removal and deodorization equipment.

Heat source ①: Adopt natural gas combustion, plus heat storage type, to improve the combustion efficiency of natural gas.

Heat source ②: Use biomass particles, wood chips, branches, straw, coal, etc. as fuel.

Drying equipment: break up drum dryer. There is a high-speed dispersing shaft inside the dryer to disperse the viscous sludge, solve the problem of sludge viscosity, and improve the heat exchange efficiency. Set one, two, three, four, five and six working areas for the drying process in the dryer, and the moisture content of the material is less than 25%. The entire drying process is completed and discharged from the dryer to enter the next process.

Dust removal and deodorization equipment: The system adopts a four-stage dust removal and deodorization method, and a cyclone dust collector can remove dust particles in the exhaust gas. The second stage pickling method removes odorous gas, the third stage uses alkaline washing method to remove odorous gas, and the fourth stage uses ultraviolet decomposition method. Odor gas can be controlled within 2000 dimensionless.

Features of sludge dryer
1. Reasonable zoning, so that materials are dispersed.
2. The arch breaking and rapping device effectively solves the problem of material agglomeration and movement obstruction during the drying process of the material, the body and the material lifting device.
3. The material lifting and spreading device makes the material and gas exchange efficiency.
4. Adopting the downstream drying process of materials and hot air flow, while maintaining the original activity of materials.
5. The automatic temperature monitoring and control system makes the system easy to operate.
6. The frequency conversion technology is used to adjust the rotation speed of the cylinder and the contact time between the material and the hot flue gas.
