Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated, illustrate advantage of the present invention and the outstanding contributions relative to prior art further, understandable, following embodiment is only the detailed description to the better embodiment of the present invention, should not be interpreted as any restriction to technical solution of the present invention.
As shown in Figure 1, rubbish, appropriate sodium metasilicate, soda ash, non-hydrogen catalyst, defoamer, the flocculants such as greasy dirt rubbish and dead pig are together added from charging aperture 19 and starts combustion chamber 3, reactor 1 is heated to about 300 degree, along with temperature raises, the gas that reaction produces and oily liq go out 4 by oil gas gradually and accelerate complete reaction by catalytic tower 5, enter settling tank 6 again, wherein entrained solid particle drops and to precipitate in water, residual gas and oily liq successively by condenser 7, negative pressure device 8, oil water separator 9, gas purifier 10.
In condenser 7, the oily liq of condensation enters into oil water separator 9, the oil separated by the row of conduits on oil water separator 9 top to oil storage tank 12; Be connected with wastewater disposal basin 11 bottom oil water separator 8, collect the waste water of discharging; Remaining gas is from the row of conduits on oil water separator 9 top to gas purifier 10, pipeline inserts below the liquid level of water in gas purifier 10, not liquid gas is contained, through row of conduits in combustion chamber 3, as the part of fuel of combustion chamber 3 in the gas that gas purifier 10 is finally discharged.
The flue gas produced in reactor 1 is introduced into flue gas cleaner 13 through pipeline, flow through smoke filter 14 again, and then undertaken lowering the temperature and dedusting by spray column 15, finally carry out desulfurization and drying by adsorption tower 16 pairs of flue gases, wherein blower fan 17 accelerates air flowing, and gas is after treatment environment friendly and pollution-free.
Reactor 3 is subject to transmission device 20 driven rotary when heating simultaneously, insulation cladding 2 keeps fixing, and when reactor 3 rotates, rubbish rubs, fully reflects by the spiral flap 22 on reactor 3 inwall, simultaneously cleaning device for inner wall 21 is swiped reactor 3 inwall, reaches the effect of cleaning, de-sludging.
Solid residue is expelled to ash chute 18 by reactor 3 after completion of the reaction.
