A multi-interface exhaust gas purification device

Abstract

The invention discloses a multi-interface waste gas purification device which comprises a gas feeding pipeline, a first rotary spraying tower, a second rotary spraying tower, a photocatalytic oxidation mechanism and a fan, wherein the gas feeding pipeline comprises a gas feeding pipe and multiple butterfly valves; the first rotary spraying tower comprises an air feeding box, an air discharging box and a spraying assembly; the spraying assembly comprises a spraying barrel, a rotary air inlet, a packing layer and a spraying nozzle group; the second rotary spraying tower is connected with the air discharging box; the photocatalytic oxidation mechanism comprises a housing, a filter net, a photo-oxidization assembly and a photo-catalysis assembly; the fan is communicated with the housing. According to the multi-interface waste gas purification device, the first rotary spraying tower and the second rotary spraying tower are used for spraying an alkaline liquid and an acidic liquid to remove hydrogen sulfide and ammonia gas; the rotary air inlet of the spraying assembly is connected with the spraying barrel in a tangent manner, so that gas entering the spraying barrel can upwards move in a helical manner, which promotes contact in different angles between the gas and water mists sprayed from spraying nozzles and contributes to enhancement of the spraying purification effect; moreover, the photocatalytic oxidation mechanism is used for purifying organic matters, so that the replacement of an adsorbent is avoided, and continuous purification is guaranteed.

Description

technical field [0001] The invention relates to exhaust gas treatment technology, in particular to a multi-interface exhaust gas purification device. Background technique [0002] In the amino acid preparation process, a large amount of sewage is inevitably formed. In order to facilitate the centralized treatment of sewage, the sewage generated by each workshop is generally concentrated in the sewage station. Since the sewage contains a certain amount of organic matter, it is easy to form a large amount of sewage under the action of microorganisms. The main components of the above-mentioned toxic gases are hydrogen sulfide, ammonia and volatile organic compounds. At present, most sewage stations use the process of "spray + activated carbon adsorption" to purify exhaust gas. However, the existing spray towers have low spray washing efficiency and cannot remove all harmful gases at one time. Multiple cycles of spraying are required. Easy to lead to increased energy consumptio...
