This utility model, when carrying out Treatment of Sludge, first passes through the many sludge water contents of pressure filter and tentatively filters, then
Degree of depth mummification is carried out, in evacuation group in sludge drying device in wet mud after filtration treatment is sent into sludge drying device
The evacuation downforce of part is negative pressure, now, the boiling point of moisture thus decline.Stirring along with spiral propeller
And promotion, mud is distributed on heating wall the most uniformly, and after being heated by heating wall, the moisture in mud is fast
Speed evaporation, the system that is evacuated is extracted out, then by condenser by the heat recovery in steam, then becomes condensed fluid storage
Exist in flow container.Then, the foul gass extracted out by vacuum pump with steam etc. continue to be sent to remove by vacuum pump
In smelly tower, after carrying out deodorization purified treatment, then discharge in air.
Compared with prior art, this utility model has the advantage that
(1) use evacuation assembly to material cavity indoor evacuation, cause subnormal ambient, thus so that
Moisture in mud is easier to evaporation, is possible not only to accelerate the mummification speed of mud, simultaneously can also relatively reduced externally
The temperature requirement adding thermal medium that the heating boiler in portion provides.
(2) mode of evacuation has also been beneficial at the stench in mud and the volatilization of harmful gas and concentration simultaneously
Reason, so can be concentrated stench and harmful gas very easily by pipeline and send into process in deodorizing tower.
(3) using condenser to reclaim the heat in the steam of evaporation, so the heat of recovery is after heat treatment again,
Can lead in heating chamber as adding thermal medium, heating and drying mud, thus improve the utilization rate of heat.
