An exhaust emission filtering device

Abstract

The utility model relates to exhaust treatment technical field especially, relates to a kind of exhaust emission filtration equipment, including pretreatment tank, reaction tank, filter assembly, guide component, transmission pipe, mounting plate, multiple spray heads and bubble dispersion component, by water inlet injects treatment liquid into reaction tank, exhaust gas enters the pretreatment tank by air inlet pipe, under the action of guide component, filter assembly is preprocessed to the exhaust gas passing through, remove particulate matter and small amount of harmful impurities in exhaust gas, after preprocessing, it is conveyed to mounting plate by transmission pipe, and it is sprayed into treatment liquid by spray head, form bubble, make it and treatment liquid fully contact and reflect, simultaneously, bubble dispersion component operates, and large bubble is scattered into small bubble and further increases the contact area with treatment liquid, reduce the rising rate of bubble, prolong contact time, solve the problem that by dust-settling device to exhaust gas is sprayed, exhaust gas and spraying liquid are not fully contacted, and contact time is shorter, further influence exhaust gas treatment effect problem.
