Integrated continuous harmful refuse processing method and device of cracking furnace and incinerating furnace

Abstract

High temperature fuel gas produced in the complete combustion inside the secondary furnace is used to heat indirectly the cracking inner tube in the continuous arranged cracking furnace, so that the waste in the vacuumed cracking tube cracked and gasified in the oxygen-free condition without being oxidized to product secondary harmful gas. By cooperating with the other design, the present invention can hot crack harmful waste completely without secondary pollution.

Description

technical field [0001] The invention relates to a hazardous waste treatment method, in particular to a continuous hazardous waste pyrolysis furnace and incinerator treatment integration system. Background technique [0002] At present, the more advanced treatment methods for medical waste and hazardous industrial waste are the use of primary and secondary furnace incineration, fluidized bed incineration, and even plasma to achieve high temperature treatment; among them, plasma is due to high equipment costs and Affected by the scope of use of plasma, although it can reach high temperature, it is difficult to process uniformly, and the treatment cost is too high to achieve resource recovery; fluidized bed incineration treatment can process oily sludge and difficult to mix with air Waste, because it cannot be pyrolyzed under anoxic conditions, and cannot be completely burned, the destruction and removal rate of harmful substances is too low, and combustion and thermal cracking...

[0002] At present, the more advanced treatment methods for medical waste and hazardous industrial waste are the use of primary and secondary furnace incineration, fluidized bed incineration, and even plasma to achieve high temperature treatment; among them, plasma is due to high equipment costs and Affected by the scope of use of plasma, although it can reach high temperature, it is difficult to process uniformly, and the treatment cost is too high to achieve resource recovery; fluidized bed incineration treatment can process oily sludge and difficult to mix with air Waste, because it cannot be pyrolyzed under anoxic conditions, and cannot be completely burned, the destruction and removal rate of harmful substances is too low, and combustion and thermal cracking occur simultaneously during waste incineration, so it is impossible to clearly treat hazardous waste. Moreover, the composition and concentration of the generated gases that produce harmful air pollution are relatively large, so the air pollution treatment equipment and costs remain high, and the primary and secondary furnaces are used to treat medical waste, because the primary furnace is also used for combustion and thermal cracking It happens at the same time, so the harmful pollution sources after the secondary furnace combustion treatment have many components and high concentrations, resulting in the problem that subsequent treatment is not easy
