A kind of sludge treatment technique of substance.Biogas combustion radiator 2 the heat that solar light is insufficient or solar energy provides not
It is enough to open when dewatered sludge and uses.
It is specifically described in conjunction with workflow of the attached drawing to the system.
Sludge to be processed first passes around feed system 14 by Belt Conveying to greenhouse, then will be to dry by paving system 15
The sludge of change, which is laid in, to be moved on porous floor 4.
Then opening greenhouse bottom axial flow blower 6 keeps outdoor air flat too into step type by air intlet 17
Positive energy heat collector 1, outdoor air can be sufficiently heated in the interlayer of heat collector 1, be conveyed after heating by air outlet slit 18
Into greenhouse.Heat collector 1 is followed successively by transparent cover plate, collecting plate, absorber plate, thermal storage unit and outline border from top to bottom.Transparent cover plate
The distance between collecting plate is 5cm, and outdoor air enters in greenhouse after being sufficiently heated in this space.
After being filled with air in greenhouse and being heated, bottom and side wall axial flow blower 6 is closed, is sent by controlling exhaust blower
Wind velocity and flow etc. make hot-air carry out desiccation to sludge by heat radiation, thermal convection in inside greenhouse, pass through simultaneously
The indoor temperature of temperature sensor detection temperature, humidity sensor detect the moisture and moisture content in the air in sludge, pass 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 lower, when thermic load needed for being not enough to provide dewatered sludge,
Intelligent automatic control system 7 opens motor-operated control valve 10, so that biogas combustion radiator 2 is started to work, biogas and air are with certain
Ratio is burnt on infrared combustion plate, generates 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
It carries out 360 degree and turns over throwing, sludge lower surface is made to obtain desiccation.When detecting that the moisture in air reaches saturation state, bottom is opened
Indoor saturated air is discharged in portion and side-wall shaft stream wind exhaust blower 6, enters the air of Sludge Surface by original saturation state
Unsaturated state promotes moisture in sludge to ambient air vaporization.
The tail gas generated after sludge drying is discharged in axial flow blower 6, and tail gas is mainly by hydrogen sulfide, methyl mercaptan, toluene and ammonia
Gas composition, so can just be discharged into atmosphere after handling these gases, tail gas initially enters in washout tower 8 by air hose, water leaching
Tower material is Corrosion-proof steel products, 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 mixed solution that the solution that acid tower is selected is sodium bicarbonate and sodium hypochlorite, pH value control exists
Within the scope of 9-14, except acid tower mainly removes the acidic odors gas in tail gas, the gas after deodorization is drained into atmosphere.
The humidity that moisture percentage in sewage sludge after throwing is reduced to needs is turned over by turning machine for sludge 5 when humidity sensor detects
When, desiccation is completed, and sends out greenhouse after collecting sludge by material-receiving system 16.
After a desiccation is completed, mobile porous floor 4 cleans up the sludge residue fallen on steel plate 12.
