Biomass Fuel Dispersing Sludge Rotary Dryer
Product Introduction
With the development of industry and the acceleration of urbanization, the amount of sewage sludge and municipal sewage sludge has been continuously increased, and the resulting large amount of sludge has seriously affected people's production and life, causing serious pollution to the environment. The problem of sewage sludge treatment has become a major environmental problem that needs to be solved in today's society.
The effective means of sewage treatment is to press and dewater 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 free of pathogens. It can be used as fertilizer, soil improver and substitute energy, etc.
For the living homes with blue sky, clear water, and pure land, Jiutian Machinery has carried out repeated technical research and practice on the characteristics of the current sludge treatment and has carefully created a new generation of the environmentally friendly and energy-saving drying system. The equipment has mature technology, stable operation, and convenient operation and maintenance.
Working Principle
The drying system consists of a heat source, drying equipment, conveying equipment, dust removal, and deodorizing equipment.
Heat source: Using biomass pellets, wood chips, branches, straw, coal, etc. as fuel
Drying equipment: Using patented products, dispersing drum dryer. Inside the dryer, there is a high-speed running shaft that disperses the viscous sludge to solve the problem of sludge viscosity and improves heat exchange efficiency. In the dryer, six drying process working areas are respectively set, and the final material moisture is less than 25%. The whole drying process is completed, and the drying machine is discharged to the next process.
Dust removal and deodorization equipment: This system adopts four-stage dust removal and deodorization method, and a first-stage cyclone dust remover can remove dust particles in the exhaust gas. The second acid washing method removes the odor gas, the third stage uses the alkali washing method to remove the odor gas, and the fourth stage uses the ultraviolet ray decomposition method. The final odor gas can be controlled within 2000 dimensionless.
Characteristics
1. The advanced circulating air technology guarantees the stable low oxygen content of the sludge drying system and ensures the safe operation of the system.
2. Energy-saving and low operating costs.
3. The exhaust gas discharged from the system, after deodorization system and wet spray treatment has no dust and no odor, and meets environmental protection requirements.
4. The unique broken arch and rapping device effectively solves the problem that the material is bonded to the body and the lifting device and the material agglomeration and movement are blocked during the drying process, and the drying strength is 3-5 times that of the ordinary drying equipment.
5. The wet sludge is dried and granulated in one step in the dryer; the system footprint and auxiliary equipment investment are greatly saved.
6. It has a wide range of applications and can adjust operating parameters according to different types of sludge properties.
7. It can realize intelligent control, automatic adjustment of operating parameters, and the dryer is always in the best state to ensure uniform and stable sludge moisture.
Application
Widely used in various types of sludge drying, such as electroplating sludge, tannery sludge, chemical sludge, oil field sludge, municipal sewage treatment plant sludge, activated sludge, sewage sludge, petrochemical sludge, paper sludge, printing and dyeing sludge, biological fermentation bacteria residue and other high-humidity materials drying.
