Sludge Dryer Manufacturing Fertilizer Processing Machinery

Product Description

Product Description

Sewage sludge is primarily derived from waste water which also consists of a variety of other substances. Prior to drying the sludge, free water is removed by mechanical means such as a belt press or firame preas to achieve around 35--40% dry solids.Then the sludge pases to the Rotary Dryer for removal of remaining water to achieve around 85% dry solids.    

Sludge dryer widely used for drying sludge, sewage sludge, textile sludge, municipal sludge, mineral slag,etc.

 

 

 

Working Principle

  The drying system contains a heat source, drying device, conveying device, dust removing, and deodorizing device.

  Heat source: It uses combustion natural gas and external regenerative heat to improve the combustion efficiency of natural gas.

  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 material is discharged from the dryer to the next process.
  Dust removal and deodorization equipment: This system adopts a four-stage dust removal and deodorization method. The first-stage cyclone dust collector can remove dust particles from exhaust gas; the second-stage acid washing method removes the odor gas, the third-stage uses the alkali washing method to remove the odor gas; the fourth-stage uses the ultraviolet ray decomposition method. The final odor gas can be controlled within 2000 dimensionless.

Product Features

1. High security. The advanced circulating air technology guarantees the stable low oxygen content of the sludge drying system and ensures safe operation.

  2. Energy-saving and low operating costs.
  3. Clean and environmentally friendly. The exhaust gas discharged from the system is treated by the deodorization system and wet spray treatment. It has no dust and no odor and meets environmental protection requirements.
  4. Advanced technology and reliable performance. The unique broken arch rapping device effectively solves the problem that the materials are bonded to the machine and the lifting device and the material agglomeration and movement are blocked during the drying process, the drying strength is 3-5 times that of the ordinary drying equipment.
  5. The investment cost is low. The wet sludge is dried and granulated in one step in the dryer; the system footprint and auxiliary equipment investment are greatly saved.
  6. Strong adaptability, suitable for semi-drying and full drying of sludge. Widely range of applications, the operating parameters can be adjusted according to different types of sludge properties to ensure the stable operation of the system.
  7. Simple and convenient operation. 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.
 

Applications

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, sewer sludge, petrochemical sludge, paper sludge, printing and dyeing sludge, biological fermentation bacteria residue and drying other high-humidity materials such as various kinds of dregs.
