A device for treating dioxin in flue exhaust gas

Abstract

The invention discloses treatment equipment for dioxin in flue waste gas. The equipment comprises a purification disk, the interior of the purification disk is provided with a treatment chamber, the interior of the treatment chamber is slidably connected with double-layer isolation rings, and an annular filter net is arranged between the double-layer isolation rings; and a partition device locatedbetween the double-layer isolation rings is arranged on the inner wall of the top end of the treatment chamber. The equipment utilizes the chemical properties that the dioxin can be dissolved in grease to make the waste gas pass through a pipeline containing the grease for purification treatment; an annulus-type station switching structure is adopted, so that the filter net sequentially realizesthe three processes of grease spreading, filtering, and dioxin-containing grease removal, and the circulation treatment of the dioxin in the waste gas is realized; and a pressure sensor is combined with a structure that can be rotated by blowing of flue gas, the greater the flue gas circulation speed, the greater the generated centrifugal force, and the faster the equipment operation controlled bythe sensor, so that the combination ratio of the grease and the waste gas is guaranteed, and the treatment effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of dioxin treatment, in particular to a dioxin treatment device in flue exhaust gas. Background technique [0002] Traditional flue gas contains a large amount of dioxin-like substances, but the existing technology is not mature enough to treat dioxin in fly ash, and the treatment effect is poor. The commonly used method is the incineration method, ensuring that the temperature in the incinerator is higher than 50 degrees in the 8 connecting tanks, preventing the formation of dioxins and decomposing a small amount of dioxins that have been generated. However, this method not only requires high energy consumption, but also requires follow-up support The combination of cooling tower and activated carbon requires complicated process, and it is difficult to control the temperature, so the treatment effect is not ideal. [0003] As we all know, dioxin is a colorless, odorless, and highly toxic fat-soluble substa...
