Descriptions

Sludge refers to sediment, particulate matter and floating matter produced when wastewater is treated by physical methods, chemical methods, physical and chemical methods, and biological methods. The main sources of sludge are: domestic sewage sludge, industrial wastewater sludge and water supply sludge.

The development of sludge drying treatment technology has made sludge agricultural, sludge fuel and sludge incineration possible. 

The environmentally friendly sludge dryer designed and manufactured by our company can dry the sludge to the required moisture and facilitate the production of sludge bio-organic fertilizer.


Working principle

The sludge is conveyed by the screw conveyor to the feeder, and then enters the sludge dryer drying chamber through the chute. As the drum of the dryer rotates, the sludge is led to the inclined lifting plate and is lifted to the center of the cylinder, gradually falling to form a curtain. The high temperature gas stream passes through it, preheating the sludge and evaporating part of the water. 

At the same time, the material entrained by the wing plate is lifted and sprinkled, and repeated, the material and the hot air flow are convective and contact heat exchange. 

The cleaning device can clean the sludge adhering to the inner wall and the outer wall of the lifting plate, and at the same time, it also plays a role in breaking the sludge ball. 

Finally, after the sludge is dried, it becomes a loose material with low moisture and is discharged from the discharge port.

Fine dust is collected and recovered by a cyclone. 

The high-temperature exhaust gas is depleted by deodorizing equipment and then emptied.


Structure

The sludge dryer is mainly composed of the heat-supply system, the feeding system, the drying system, the discharging system, the dust-collecting system, and the electronic control system.


Characteristics

1).The mechanial level content of rotating drier is high and its productive capacity is large.

2).Because the resistance when fluid passes through the cylinder is small,the consumption of power is low.

3).Have strong adoptability to raw materials.

4).Its operation is stability and the cost of operation is cheap.The homogeneity of dried product is good.
