In view of the shortcomings of the prior art, the technical problems to be solved in the utility model is that providing a kind of differential sludge does Dry machine, realize efficient, energy-saving and environmental protection, the processing sludge of safety.
Designed for this utility model and use following scheme:
A kind of differential sludge drier, including homogenizing device, hothouse, drawing mechanism, drying system and condensed system System;The homogenizing device, hothouse and drawing mechanism are sequentially communicated, and are laid with the conveyer belt inside three;It is described dry Drying system includes heat exchanger, and the outlet of the heat exchanger is connected with heated compressed air pipeline, and the outlet of heat exchanger leads to Cross air-heater and be connected with reflux cycle air duct;Length direction of the heated compressed air pipeline along conveyer belt is laid in dry Above dry room, heated compressed air pipeline is evenly distributed on the heated compressed air pipe joint above hothouse by several Connected with hothouse, be heated compressed air room above the conveyer belt in the hothouse, be vacuum chamber below conveyer belt, it is described In heated compressed air room diffuser is laid with below each heated compressed air pipe joint;The condenser system is included by mistake Filter component and condense the condensing unit of tube assembly composition, the inlet end of the condensing unit is connected by condensing air hose with vacuum chamber Logical, the outlet side of condensing unit is connected with reflux cycle air duct.
Further, the conveyer belt is netted conveyer belt, and conveyer belt material is PPS plastics or stainless steel.
Further, the filter assemblies use stainless steel filter core.
The beneficial effects of the utility model are:
The utility model directly in the Equipment Foundations of dewatered sludge, will compress hot-air in original tradition based on pressure difference design Being sprayed into by diffuser with mode of jet in hothouse, airflow volume expands rapidly on quick stripping conveyer belt moisture in sludge, Simultaneously under sludge layer resistance and air-heater effect, the hot-air below hothouse conveyer belt is changed into negative pressure by malleation rapidly, Vacuum chamber is formed, because hot-air saturation degree reduces, while the boiling point of water reduces under negative pressure, and sludge reclaimed water gets rapid steaming Hair;Meanwhile front and rear air-flow realization is dried in system of the present utility model and is recycled, whole system closure designs, without useless Gas disposal, eliminate the demand to deduster, washer or exhaust chimney, and associated exhaust discharge permit, can efficiently, section Energy, environmental protection, the processing sludge of safety, simple to operate, maintenance is few.The sludge handled by the utility model, moisture content can drop To 30%, compared to traditional drying equipment, operating cost can reduce by 45%.
