After air is filled with greenhouse and is heated, bottom and side wall axial flow blower 6 are closed, by controlling exhaust blower to send
Wind velocity and flow etc., hot-air is carried out desiccation to sludge by heat radiation, thermal convection in inside greenhouse, pass through simultaneously
Temperature in temperature sensor detection greenhouse, humidity sensor detect the moisture and water loading of the air in sludge, passed through
Intelligent automatic control system 7 controls exhaust blower air-supply air quantity and ventilation velocity.
When temperature sensor detects that indoor air temperature is relatively low, is not enough to provide the thermic load needed for dewatered sludge,
Intelligent automatic control system 7 opens motor-operated control valve 10, biogas combustion radiator 2 is started working, biogas and air are with certain
Ratio is burnt on infrared combustion plate, produces infrared ray, and for infrared ray by the heat radiation dewatered sludge of radiator, biogas can be by
The sludge of sewage treatment plant is made after carrying out Anaerobic Digestion, prepares convenient, abundance.
When humidity sensor detects the moisture content of Sludge Surface in 40%-60%, start turning machine for sludge 5 to sludge
Carry out 360 degree and turn over throwing, sludge lower surface is obtained desiccation.When detecting that the moisture in air reaches saturation state, bottom is opened
Portion and side-wall shaft stream wind exhaust blower 6 discharge the saturated air of interior, the air of Sludge Surface is entered by original saturation state
Unsaturated state, promote moisture in sludge to ambient air vaporization.
Axial flow blower 6 discharges caused tail gas after sludge drying, and tail gas is mainly by hydrogen sulfide, methyl mercaptan, toluene and ammonia
Gas is formed, so can just be discharged into air after handling these gases, tail gas is initially entered in washout tower 8 by airduct, water woods
Tower material is Corrosion-proof steel productses, and washout tower can adsorb a small amount of odorous gas.The gas come out from washout tower, which enters, removes acid tower 9,
Material is Corrosion Resistant Frp, and except the solution that acid tower is selected is sodium acid carbonate and the mixed solution of sodium hypochlorite, pH value control exists
In the range of 9-14, the acidic odors gas in tail gas is mainly removed except acid tower, the gas after deodorization is drained into air.
When humidity sensor detects that the moisture percentage in sewage sludge turned over by turning machine for sludge 5 after throwing is reduced to the humidity of needs
When, desiccation is completed, and greenhouse is sent out after collecting sludge by material-receiving system 16.
After a desiccation is completed, mobile porous floor 4, the sludge residue to drop on steel plate 12 is cleared up.
