What type of municipal sludge deep dewatering municipal sludge filter press is suitable?

The main source of municipal sludge? Sludge mainly comes from sewage treatment plant. The treated sludge contains heavy metals and is easy to breed bacteria. If it is not handled properly, it will pollute water and atmosphere.

"High temperature and high pressure airtight environment can dispel all kinds of pollutants ." At the beginning, the core technology of sludge disposal was locked in the incineration mode, "the incineration investment is huge, the operation and management are complex, and the energy consumption and operation cost are both very high, which cannot be fully promoted in the short term ."

"This is a war without gunpowder smoke. We must solve this difficult problem !"

How to ignite? How to control the proportion of coal? How to set the boiler? Sludge treatment is still a worldwide problem up to now, and there is no case to study in China. It is difficult to burn sludge. The real difficulty is not only how to dehydrate deeply, how to burn, and how to solve the problem of flue gas, however, any process that fails to meet the expectation will lead to the failure of this project.

For example, the problem encountered in the first step is dehydration. "The water content of sludge produced in sewage treatment is very high. The water content of undehydrated sludge is usually more than 95%, and the water content of sludge after conventional dehydration is also as high as 80%, which used to be mainly based on landfill, but the sludge transportation cost is high and the stacking takes up a large amount of land. The existing technologies in China are basically sludge concentration and dewatering. After sludge dewatering, the general moisture content can only be reduced to 70%-80% .".

Our company researches and develops sludge deep Dewatering technology municipal sludge filter press, which reduces the moisture content of dehydrated sludge to 50%. At present, this technology is far ahead in China. "Our deep dehydration technology is efficient, economical and has strong market competitiveness ."

"The sludge after taking off the water is like coal cake, which can be solidified into blocks ." The dry mud after deep dehydration can generate heat energy of 3 megajoules/ton, which is a kind of fuel with low calorific value. Because the calorific value is low, in order to make the sludge fully and stably burn, coal needs to be added. The mature technology at home and abroad has been absorbed and transformed to form the current set of technology. The biggest feature of this technology is that it can directly burn sludge, and it only needs 10%-15% of auxiliary fuel coal. There is no precedent in China for the project that sludge accounts for such a high proportion of the total amount of the furnace.
