Project Background: past, many chemical companies will belt filter press sludge pulled after dumping outside the plant , pollution of the surrounding environment, is now prohibited by the state sludge poured outside , so companies need to own the sludge drying and incineration or to the building brick factory with . Therefore sludge drying project will be of great potential for the future . My company developed to revitalize dried hollow paddle dryer is particularly suitable for dyeing sludge, sludge textiles , dyeing sludge, biological sludge , petrochemical sludge, sludge, paper sludge , sewage sludge .

How it works:
Hollow shaft lined with dense wedge-shaped hollow blades , axial flow through the heating medium through the hollow blades . The effective heat transfer area per unit volume is large, the heat medium temperature from 40 ℃ to 320 ℃, can be water vapor, hot water or thermal oil can be like. A heat transfer medium through the rotary joint flows through the housing jacket and hollow stirring shaft , the stirring shaft hollow type according to the heat medium having a different internal structure , to ensure optimum heat transfer.
And the blade is heated by injecting steam into the jacket while simultaneously through the discharge port into the upper portion of the heated dry air through the further drying , thereby greatly increasing the dry strength of the device. Evaporated moisture from the dryer exhaust out through the baghouse filtration, dried powder recovered down , wet air from the water after the dust suction fan vented to the outdoors .

Device characteristics:
Paddle dryer low energy consumption : Due to the indirect heat , not a lot of air to carry away the heat , and set the dryer wall insulation, for pasty materials , water- tight demand 1.2KG 1KG evaporation of water vapor .
Paddle dryer system costs low : has a huge effective heat transfer surface per unit volume , to shorten the processing time , the device size becomes smaller. It greatly reduces the construction area and building space .

Handle a wide range of materials : the use of different media , both can handle the heat-sensitive materials , processed materials can be heat treated . Common media are: water vapor, heat conduction oil , hot water, cooling water. Continuous operation may be either intermittent operation can be applied in many fields.

Environmental pollution : carry small amounts of air , dust entrained material rarely . For contaminated materials or conditions to be recovered solvent , can be closed loop .

Low operating costs : normal operation of the device , only one person / day . Low-speed stirring and reasonable structure. A small amount of wear and maintenance costs low.

Stable operation : As the wedge-shaped blade special compression - expansion of stirring, the material in contact with the heat transfer surface of the particle component in the axial section , the material temperature , the humidity , the mixing temperature gradient is small, thus ensuring the stability of the process sex .
