Organic waste is in feed system is delivered to pyrolysis furnace, and gas phase is through gas-solid separator, rectifying column, condenser system after the combustion system heating; Do not have the fixed gas of condensation to enter multifunctional separator after check-valves enters the hybrid chamber mixing; This process can form negative pressure state, and handle contains the hydrogen chloride gas precursor reactant, is neutralized into neutral gas in hybrid chamber.
By alkali liquor circulating system, the fixed gas in the thermal cracking system is mixed in the venturi of recirculated water or spray chamber and in and the acidic materials in fixed gas, then bring in the multifunctional separator of lower end, make the thermal cracking system form micro-vacuum state; In the partially liq oil droplet of by dividing plate, fixed gas being brought in multifunctional separator and the acidic materials of fixed gas and after separating substances; Enter the fixed gas air accumulator of back after gas separates comparatively totally by the gas-liquid separation section, can enter the combustion system postcombustion burning of back.
Compared with prior art, the present invention has following outstanding advantages:
1) pernicious gas solved the cracking fixed gas in forming the process of little negative pressure in, extended simultaneously the service life of process equipment and optimized environment.
2) owing to having added the alkaline matter mixing in hybrid chamber circulation, contain harmful hydrogen chloride fixed gas and form negative pressure in hybrid chamber, formed cavitation effect, strengthened the mass transfer effect to sour gas and akaline liquid, therefore, in speed and more thorough;
3) air inlet that is communicated with of the present invention and pyrolysis furnace, and and gas storage tank connected gas outlet, it is divided into two parts by alkali lye, both are split into independently process system part, therefore, have improved security.
