Technical Field

[0002] Metal fiber sintered felt is made of metal fibers with a diameter of micron level through non-woven laying, stacking and high-temperature sintering. Multi-layer metal fiber felt forms a pore gradient with different pore diameter layers, which can be controlled to obtain extremely high filtration accuracy and greater dirt holding capacity than single-layer felt.

In the actual use of the spray adsorption exhaust gas purification device, the exhaust gas entering the purification box can enter the purification channel formed by the outer sleeve and the inner cylinder, and fully react with the exhaust gas under the action of a plurality of atomizing nozzles in the purification channel, thereby effectively ensuring the full contact between the exhaust gas and the atomized purification liquid, and further effectively ensuring the adequacy of the exhaust gas purification. However, the above-mentioned spray adsorption exhaust gas purification device cannot clean and collect the filtered impurities due to its structure, which adds an additional cleaning step during the purification process, making the operation process more cumbersome. At the same time, there are still many odors in the exhaust gas, and direct emission will affect the surrounding air quality. Therefore, it is necessary to provide a new sintered felt exhaust gas purification adsorption device to solve the above-mentioned technical problems. Utility Model Content
