Flue gas ultra-clean emission processor

Abstract

The invention discloses a flue gas ultra-clean emission processor, which relates to the technical field of flue gas treatment. The flue gas ultra-clean emission processor comprises a box body, a purification chamber and a filter bag borne on the box body, and an air inlet chamber and an air outlet chamber arranged on the box body. The interior of the purification chamber is divided into a plurality of parallel cavities through partition plates, an inlet valve communicated with the air inlet chamber is arranged below each cavity, and an outlet valve communicated with the air outlet chamber is arranged above each cavity. A blowing assembly is further arranged at the top of the cavity, and the blowing assembly is used for blowing the activated carbon into the ash discharge hopper at the bottom when the activated carbon on the filter bag is adsorbed to be saturated; an activated carbon blowing device is also arranged at the bottom of the cavity and is used for uniformly blowing activated carbon into the cavity and attaching the activated carbon to the filter bag. By adopting the technical scheme, the device has the advantages that dioxin in flue gas can be adsorbed, and activated carbon can be replaced and added under the condition that a treatment line is not stopped.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a flue gas ultra-clean emission processor. Background technique [0002] With the improvement of urbanization level and the change of people's consumption awareness, a lot of garbage is produced around us, especially domestic garbage and medical waste. Usually, there are two types of waste disposal technologies: incineration and non-incineration. Non-incineration technology is due to waste disposal The garbage is incomplete and requires secondary treatment, which has been gradually eliminated; the development of incineration technology has achieved a comprehensive and thorough treatment of garbage. However, incineration also brings about a problem, that is, the appearance of dioxins. At present, in addition to the front-end process of the incineration treatment line, the only final treatment of dioxins is simple activated carbon and non-metallic material carrier cataly...

AI Technical Summary

Problems solved by technology

[0004] There are generally two technologies for activated carbon to adsorb dioxins. One is to inject activated carbon powder into the front end of the dust collector, enter the cloth bag together with the dusty flue gas, and filter it out through the cloth bag. Although this technology can absorb a certain amount of dioxins, Since it is sprayed together with the dust, it will block the open pores of the activated carbon and reduce the adsorption efficiency, so it is difficult to meet the requirements of ultra-clean emission

And the activated carbon is filtered out together with the dust in the state of no adsorption saturation, which also causes waste of activated carbon and increases the operating cost of the enterprise

The other is to use a fixed activated carbon bed and place activated carbon particles in a closed tank. After the flue gas passes through, the activated carbon will adsorb dioxins. Although this technology can work, it must be stopped when the activated carbon is saturated. The furnace is used to replace activated carbon for a long time, so that the incineration line cannot run continuously, and it cannot meet the requirements of the national standard for medical waste incineration and disposal
