Embodiment Construction

[0020] Such as figure 1 Among them, the gas pipeline I (3) connects the top of the chimney (2) with the fan (4), and the gas pipeline II (5) connects the air inlet of the fan (4) and the shower pool (6). The top of the shower pool (6) has a device that sprays the water flow at a high speed, and a water pump is installed at the bottom of the shower pool (6), and the water pump is connected to the top device; the shower pool (6) is equipped with a certain depth of water And add the saponification oil of suitable concentration; The shower tank (6) can be made of transparent material so as to observe; The bottom of the shower tank (6) has an outlet pipe. The air pipeline III (7) connects the air outlet of the shower pool (6) to the air inlet of the air compressor (8), one end of the air pipeline IV (9) is connected to the air outlet of the air compressor (8), and the other end Connect to the bottom of the reaction tank (10). The top of the reaction tank (10) has a feeding port t...

Abstract

The invention relates to a soot treatment device of casting, metallurgy and other relevant industries. The device is a cupola dust and waste gas treatment device which needs two times of treatment, namely, firstly using atomized water and then using aqueous alkali for treatment, and can be suitable for small and medium-sized enterprises. The device mainly comprises a cupola, a chimney, a fan, a shower bath, an air compressor, a reaction tank, an air pipeline, etc. The air pipeline sequentially and circularly connects the cupola, the chimney, the fan, the shower bath, the air compressor, the reaction tank and the cupola. The shower bath is filled with water with certain depth, proper concentration of saponified oil is added, and the top part of the shower bath is provided with a device that atomizes water flow downward at high speed. The reaction tank is filled with aqueous alkali, after compressed by the air compressor, the waste gas with dust removed is sent to the bottom part of the reaction tank, and the air outlet end of the reaction tank is positioned at the upper part of the reaction tank. The dust and waste gas generated in the combustion of the cupola are sequentially treated by the shower bath and the reaction tank for two times, and the soot can be treated completely.

Description

technical field [0001] The invention relates to a dust treatment device for foundry, metallurgy and other related industries, in particular to a cupola dust exhaust gas treatment device which uses atomized water first and then alkali solution to absorb dust and harmful substances through two treatments. Background technique [0002] In foundry, metallurgy and other related industries, it is inevitable to emit a large amount of dust and exhaust gas through the chimney, which contains a large amount of harmful gases such as carbon monoxide, nitrogen monoxide, carbon dioxide, nitrogen dioxide, sulfur dioxide, sulfur trioxide, hydrogen sulfide, etc. As we all know, some enterprises use high chimneys to discharge dust and exhaust gas, but they can only reduce the degree of pollution in a small area. Some enterprises also adopt smoke and dust treatment devices, but the cost is too high and the effect is not ideal. In fact, more small and medium-sized enterprises that use cupolas c...
