Problems solved by technology

[0006] The above-mentioned incineration device needs cooling equipment, air preheater, washing and dust removal device, and spray absorption device. The process is complicated. Because the flow of waste gas generated by incineration is extremely unstable and cannot be controlled, part of the waste gas cannot be treated, which affects the Treatment efficiency of incineration waste gas

Embodiment Construction

[0035] like figure 1 As shown, a kind of incineration exhaust gas quenching treatment system of the present invention comprises an exhaust gas buffer device 1, a quench tower and an induced draft fan 2, and the induced draft fan 2, the exhaust gas buffer device 1 and the quench tower are sequentially connected in series through connecting pipes;

[0036] The above-mentioned quenching tower includes an outer steel jacket 3 and an inner graphite jacket 4. The upper and lower ends of the outer steel jacket 3 are respectively covered with an upper spray cover 5 and a lower cover 6; Inside the steel sleeve 3, and form a cooling water cavity 7 that can accommodate the circulation of cooling water with the inner wall of the outer steel sleeve 3. The inner wall is a spray inner cavity 8 for exhaust gas spraying, and its upper end passes through an upper head 9 It communicates with the upper spray cover plate 5, and its lower end directly communicates with the lower cover plate 6;

Abstract

The invention relates to an incineration waste gas quenching treatment system, which comprises a waste gas buffer device, a quenching tower and an induced draft fan, wherein the induced draft fan, the waste gas buffer device and the quenching tower are sequentially and serially connected by a connecting pipe, the quenching tower comprises an outer steel sleeve and an inner graphite sleeve, an upper spraying cover plate and a lower cover plate respectively covers the upper end and lower end of the outer steel sleeve, the inner graphite sleeve is in a tube shape, and is coaxially arranged in the outer steel sleeve, a cooling water containing cavity for containing cooling water to flow is formed between the inner graphite sleeve and the inner wall of the outer steel sleeve, the inner wall of the inner graphite sleeve is a spraying inner cavity for spraying the waste gas, the upper end of the inner graphite sleeve is communicated with the upper spraying cover plate through an upper sealing head, and the lower end of the inner graphite sleeve is directly communicated with the lower cover plate. The incineration waste gas quenching treatment system has the advantages that the structure is simple, the incineration waste gas is slowly provided for the quenching tower to be treated at uniform speed through the waste gas buffer device, then the waste gas is subject to quenching treatment by the quenching tower, the waste gas produced by incineration at high temperature is effectively treated, and the problems of pollution to environments, energy saving and environment protection are solved.

Description

technical field [0001] The invention relates to a waste gas treatment system, in particular to a quenching treatment system for incineration waste gas. Background technique [0002] After medical waste is incinerated at high temperature, not only the waste is harmlessly reduced, but also toxic substances and dioxins are effectively treated. [0003] Dioxins can still be synthesized at around 300 degrees, so rapid cooling is required, and dioxins in the environment are difficult to degrade and eliminate naturally. It includes 210 compounds, which are very toxic, 900 times that of arsenic, and have " Known as the "poison of the century", one ten thousandth or even one hundred millionth of a gram of dioxin will bring serious harm to health. [0004] Dioxins often exist in the air, soil and water in the form of tiny particles. The main sources of pollution are chemical and metallurgical industries, waste incineration, papermaking, and pesticide production. [0005] The current...
