Tanning Sludge Dewatering Equipment Industrial Drying Machinery High Thermal Efficiency
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 high thermal efficiency
sludge drying system is going to reduce the water content of dewatered sludge from 80 + 10% to 20 +
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, raw materials for
extracting heavy metals, to realize waste utilization.
4. Advanced internal structure strengths heat exchange, that is to say, increasing thermal efficiency.
Application after drying :
1. Heavy metal recycling
During the wastewater treatment process of the smelting plant, the circuit board printing factory,
electroplating factories and other enterprises, and the sludge produced contains plenty of heavy metals
(copper, nickel, gold, silver, etc.). There will be a major pollution if these metal elements are drained, but
considerable economic benefits can be reached after extraction and refining.
2. Incineration power generation
The approximate calorific value of the dried sludge is from 1300 to 1500 calories, three tons of dry
sludge can be equivalent to one ton of 4500 kcal coal, which can be burned in the furnace mixed with
3. Building material
Concrete aggregate, cement admixture and the production of pavement encaustic brick, permeable
brick, fiber board, to make bricks by adding into the clay, its strength is equivalent with common red
bricks, and it’s with a certain amount of heat, in process of fired brick, the spontaneous combustion can
be reached to increase the heat.
4. Organic fertilizer
The dried sludge will ferment into high quality organic fertilizer after adding the cow manure, with good
fertilizer efficiency, safe and convenient use, and disease resistance and to promote growth, which can
also fertilize soil.
5. Agricultural usage
There is high content of N, P and K in the sludge, and it’s much higher than that of pig manure, cattle
manure and chicken manure, and there is rich organic compound content. It can be used as agricultural
fertilizer after the processing of high thermal efficiency sludge drying system, and can make quality soil
through re-proportioning landfill.
