Energy Saving Sludge(Coal Slime) Industrial Drying Equipment For Printing And Drying Sludge

 

Equipment Introduction :

 

Sludge refers to the sediment produced by dealing with waste water through the physical, chemical,

biological methods, According to their sources, which can be divided into electroplating sludge, printing

and dyeing sludge, tanning sludge, paper sludge, pharmaceutical sludge, sewage sludge, living sewage

sludge and petrochemical sludge, etc. Because of its features of poor mobility, high viscosity, easy to

agglomerate, and the water is not easy to evaporate and so on, it’s very hard to dry, and the high drying

technology is required (the drying technology of this drying system is also adopted to dry the coal

slime, gypsum and other similar wet sticky materials).

 

With the continuous enhance of people's awareness of environmental protection, and sludge drying

technology is also in the rapid development, the constant innovation and improvement also happens in

the aspects of energy saving, safety, reliability, sustainability. Our company energy saving sludge

industrial drying equipment is going to reduce the water content of dewatered sludge from 80 + 10% to

20 + 10%. The advantages of our system are as follows:

 

1. The weight of the dried sludge can be reduced to 1/4 weight of wet material before drying, which

greatly reduces the enterprise's environmental and economic pressure;

2. The air inlet temperature of the dryer is 600-800, and it can be used for sterilization, deodorant, etc.

at the same time of drying, and reliable guarantee will be provided for the utilization of dried products;

3. The dried products can be used as feedstuff, fertilizer, fuel, building materials, and raw materials for

extracting heavy metals, to realize waste utilization.

4. By adopting thermal resistant material on surface of shell, so as to prevent heat loss. In this way, it

reduces fuel consumption, that is to say, energy saving.

 

The dewatered sludge will be transported to feeding head of the dryer through the screw conveyor after

scattering, and then it will be sent into the inside of the dryer through the unpowered spiral sealing

feeder (the patent technology of our company), and going through several following working areas after

getting into the dryer:

 

1. Material leading-in area

 

The sludge will come into contact with the high temperature negative pressure air after getting into this

area and plenty of water will be rapidly evaporated, and the sludge can’t be formed into sticky stuff under

the stirring of large guide angle lifting plate.

 

2. Cleaning area

 

The material curtain will be formed while the sludge is lifted up at this area, and it will cause the material

stick on the cylinder wall while it’s falling down, and the cleaning device is installed at this area (Lifting

style stirring plate, X type second time stirring plate, impacting chain, impacting plate), the sludge can

be quickly removed from the cylinder wall by the cleaning device, and the cleaning device can also

crush the materials which are bonded together, so as to increase the heat exchange area, increase the

time of heat exchange, avoid the generation of wind tunnel phenomenon, improve the drying rate;

 

3. Inclined lifting plate area

 

This area is the low temperature drying area, the slime of this area is at the low moisture and loose

state, and there is no adhesion phenomenon at this area, the finished products reach the moisture

requirements after the heat exchange, and then enter the final discharge area;

 

4. Discharging area

 

There aren’t stirring plates at this area of the dryer cylinder, and the material will be rolling to the

discharging port.

The sludge gradually becomes loose after drying, and discharged from the discharging end, and then

sent to the designated position by the conveying device, and the fine dust drawn out along with the tail

gas is collected by the dust collector.

Hot air enters into the drying machine from the feeding end, and the temperature is gradually reduced at

the same time of material convection heat transfer, and the water steam taken out under the suction of

induced draft fan, and then emitted into the air after processing.
