Large Capacity Electroplating Sludge Petrochemical Sludge Drum Dryer Sewage Treatment Equipment

Product Description

Introduction of Rotary Dryer:

The muddy material drying system developed by Zhengzhou Jiutian Company is suitable for drying various kinds of sludge with high viscosity. The sludge drying system operates under negative pressure and is equipped with an enhanced heat transfer device for direct heat transfer. The drying and moisture control of the material is convenient, the operation flexibility is large, and the flow rate of the product is allowed to have a large fluctuation range. There are few high-temperature mechanical equipment in the system, simple structure, easy cleaning, low failure rate, continuous operation, low maintenance cost and wide application range.

JIutian Sludge Drum Dryer is mainly composed of hot air furnace, scattering feeder, belt conveyor, rotary drum dryer, belt outlet conveyor, draught fan, dust collector, deodorant device and electric cabinet. 

Working Principle of Rotary Dryer:

The working principle of the sludge drying equipment as following: About 80% of the moisture content for the wet sludge has stickness. Before the drying process, it first enters three roller belt-dewatering machines, and the sludge moisture removed to 55-60%. After entering the rotary drum dryer and drying, the wet sludge enters the tumble dryer and spitting into following six drying work areas: The first is the material feedstock zone. The wet mud enters this zone and contacts the high temperature hot air to rapidly evaporate moisture. The material is in a large lifting flight angle. Under the lifting flight drop and pick up, it will be introduced into the next working area without forming a bond. Second, the clean up area will repeatedly break and beat the material. In this area, the equipment is designed to break and beat all of the material by the cleaning device, and the wet mud is picked up and beaten by the grating copy board. After a large amount of wet mud is repeatedly crushed and beaten, it is broken and kneaded into 20-40mm pellets of coal slime to form the state of the material curtain, increasing the heat exchange area, increasing the drying rate, and the cleaning device reasonably cleans the mud adhered to the inner wall and prevent the wet mud from sticking. Thirdly, in the main drying zone, the wet mud that has been conducted in the second zone has been in a state of loose granularity. The material is picked up by the radial slanting flight on cascade uniformity, and it conducted full heat exchange with the hot air. Fourthly, It is beaten and broken Drying zone, where the mud is repeatedly beaten and broken, the mud particles are broken from 20-40mm to 10-20mm (customer requirements granularity), the moisture is further reduced; Fifth, the enhanced drying zone, the broken small granular mud is dense in the area from the copy board which is lifted to fully absorb the heat of the hot air and discharge the moisture to get the water requirement and prepare the material for discharge. The sixth is the outlet material. To prevent the discharge of dust, the rotary drum did not provided with lifting flight in this area, and the material is rolled and glided to the discharge opening. , The moisture of Sludge dropped to about 20-25% to dryer out, and finally complete the whole drying 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.

Sludge Dryer 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.

 Sludge Dryer 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, 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.
