Tail gas treatment equipment and method used for high-temperature drying and cleaning of oil-contained steel scrap

Abstract

The invention discloses tail gas treatment equipment used for high-temperature drying and cleaning of oil-contained steel scrap and a tail gas treatment method used for high-temperature drying and cleaning of the oil-contained steel scrap. The tail gas treatment equipment used for high-temperature drying and cleaning of the oil-contained steel scrap comprises a frame, an exhaust gas emission pipe,a sedimentation-type dust remover, a cooler, high-voltage static purifying equipment, a by-pass flue, an induced draft fan and an exhaust funnel, wherein a connection air duct is arranged on the outer portion of the exhaust gas emission pipe, two ends of the connection air duct are connected with the exhaust gas emission pipe and the sedimentation-type dust remover respectively, the cooler is arranged on the outer side of the sedimentation-type dust remover, the high-voltage static purifying equipment is arranged on the outer side of the cooler, the by-pass flue is connected with the high-voltage static purifying equipment, the cooler and the sedimentation-type dust remover separately, the induced draft fan is arranged on the outer side of the high-voltage static purifying equipment, andthe exhaust funnel is arranged on the outer side of the induced draft fan. Through cooperative work among the sedimentation-type dust remover, the cooler and the high-voltage static purifying equipment which are additionally arranged, generated tail gas can be subjected to effective treatment, up-to-standard exhausting is achieved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of high-temperature drying and cleaning of oil-containing scrap steel, in particular to a tail gas treatment equipment and method for high-temperature drying and cleaning of oil-containing scrap steel. Background technique [0002] The dismantling and recycling of scrapped vehicles is a sunrise industry in my country. As China formally steps into the ranks of automobile powers, the capacity and space of the automobile scrapping market will also expand rapidly. It is understood that the number of scrapped cars in the country should reach 3 million each year, but the number of scrapped cars that are actually recycled and dismantled by qualified scrap car companies is far from reaching this number. The recovery rate is only about 30%, and nearly 70% of scrapped cars are free. outside the supervision of government departments. At present, the loss of scrapped cars in my country is serious, and a large number o...
