2nd, by the way of supported at three point rotation, tank body keeps not deviating during its rotation, assists the bearing part abrasion of rotation Degree is small, and service life is long.

3rd, condenser portion, the high-temperature oil gas mixture that thermal cracking tank comes out enters oil gas inlet pipe, by heavy fuel separator （Usual multiple heavy fuel separator juxtapositions）, tentatively weight substance in mixture is detached, the heavy oil of initial gross separation by pipeline into Enter oil storage tank, the end of oil gas inlet pipe is connected with heavy fuel separator, cooling tube is provided between heavy fuel separator and condenser, cold Coil pipe is provided on condenser, the inlet side of coil pipe is connected to by pipeline in the outlet of cooling tube, and the outlet of coil pipe is connected by pipeline It is connected on oil storage tank, the upper end of heavy fuel separator is connected to by pipeline in the import of cooling tube, and the lower end of heavy fuel separator leads to Pipeline is crossed to be connected on oil storage tank.The utility model oil gas first passes through cooling tube cooling, then is cooled down by condenser, moreover, right The condensed water of condenser bad student does water conservancy diversion setting, increases condenser service life, improves the cooling effect of condenser,（Existing skill The return water temperature of circulating water pipe is between 32-42 degree in art, and the return water temperature of the utility model circulating water pipe is again between 25-30）, Meanwhile the same type waste tire of similary tonnage is handled, the yield for obtaining heavy oil improves 5-6%.

4th, the substance that Harmful Waste thermal cracking recycles is filled into burning Indoor Combustion（As formed after medical waste thermal cracking Carbon black, heavy oil and combustible gas etc.）, used as fuel, reduce the fuel utilization rate of pyrolysis furnace, because burning is indoor 800 degree or so temperature can not make these substance combustions complete, high-temperature gasification device be added on flue gas collecting pipe, because of air-introduced machine Effect, the velocity of flue gas by flue gas collecting pipe is very fast, is sufficiently vaporized in high-temperature gasification device to ensure it, sets three sections The decompression section turned around reduces flue gas by speed, improves the abundant degree of gasification.The combustion chamber temperature of high-temperature gasification device exists 1200 degree or more, after harmful substance is gasified totally, cool down through wet desulphurization device desulfurization, less than 40 degree are discharged from exhaust apparatus Gas, whole process avoid harmful substances from flue gases after Harmful Waste lysate burns again and generate secondary hazards.
