Embodiment Construction
[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0032] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, a waste gas purification system for an incineration furnace includes a dry dedusting subsystem 1 , a wet gas treatment subsystem 2 , and a wastewater treatment subsystem 3 .
[0033] The dry dedusting subsystem 1 includes a dust collection hood 110 and a pulse-tube dust collector 120. The dust collection hood 110 is set directly above the smoke outlet of the burnout furnace, and the dust collection hood 110 collects the waste gas generated by the burnout furnace through the induced draft fan inside it. Inhaled into the pulse cartridge dust collector 120. Wet gas treatment subsystem 2 includes spray turbulent ball absor...

The invention relates to a waste gas purification system for a destruction furnace. The waste gas purification system comprises a dry process dust removal sub-system, a wet process gas treatment sub-system and a wastewater treatment sub-system, wherein the dry process dust removal sub-system comprises a dust absorbing cover and a pulse drum type dust remover; the dust absorbing cover is arranged right above a smoke exhaust hole of the destruction furnace and is used for sucking waste gas produced by burning of the destruction furnace into the pulse drum type dust remover; the wet process gas treatment sub-system comprises a spraying type turbulent ball absorption tower, an absorbing agent circulating water tank and a circulating water pump; the wastewater treatment sub-system comprises a coagulation-sedimentation tank and a plurality of medicament tanks; the circulating water pump is also used for realizing transfer of solutions between the absorbing agent circulating water tank and the coagulation-sedimentation tank. The waste gas purification system disclosed by the invention has the beneficial effects that physical and chemical methods are comprehensively adopted, so that harmful gas and smoke dust in the waste gas are effectively removed, an environment is protected, and the problem of atmosphere pollution in a burning process of an initiating explosive device is solved.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas purification system for an incineration furnace and a method thereof. Background technique [0002] When burning scrapped pyrotechnics, high temperature, high dust, and high concentration of harmful exhaust gas will be produced. If these exhaust gases are discharged directly, they will seriously pollute the atmosphere. However, there is currently a lack of mature purification systems to treat these exhaust gases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a system and method for purifying exhaust gas of an incineration furnace, so as to overcome the above-mentioned deficiencies in the prior art. [0004] The technical solution of the present invention to solve the above technical problems is as follows: a waste gas purification system for a burnt furnace, including a dry dust removal subsy...
