Flue gas treatment system of large chimney for industrial waste gas emission

Abstract

The invention discloses a flue gas treatment system of a large chimney for industrial waste gas emission. The flue gas treatment system comprises an inner shell, and an outer shell arranged in the inner shell in a sliding manner, wherein first fixing spaces are symmetrically formed in the outer shell around the outer shell; mounting connecting rods are hinged onto the first fixing spaces; and elastic rubber rings that can be clamped with inner walls of the chimney are fixedly arranged on the connecting rods. A slide bar is pulled to slide upwards by a handle by pushing the handle upwards, a pull rod is pulled upwards by the slide bar, the connecting rods are pulled to rotate by the pull rod, so that the elastic rubber rings are clamped with the inner walls of the chimney, namely the innershell and the outer shell can be fixed on the chimney and mounted on the top of the chimney, and flue gas can be respectively subjected to dust fall treatment and water bath washing treatment. Therefore, emission of the flue gas is up to the standard, a filter screen can be automatically cleaned, manual working is reduced, the flue gas can be subjected to accelerated treatment, and the treatment rate is increased.

Description

technical field [0001] The invention relates to the field of flue gas treatment, in particular to a flue gas treatment system for a large chimney for industrial waste gas discharge. Background technique [0002] In some power plants or some chemical factories, a large amount of flue gas needs to be discharged during production. The large amount of flue gas discharged from the factory will have a great impact on the air environment. The flue gas contains a lot of dust and some particles, which is easy to Smog is formed, and the flue gas contains a large amount of acidic chemical component gas, which is easy to cause the flue gas to form acid rain after being discharged. [0003] The current method of flue gas treatment is to introduce the flue gas into the reaction tower to filter the flue gas. However, some flue gas discharged from the chimney has a large volume, and the reaction tower cannot be directly installed on the chimney. When working, the reaction tower will produc...

[0003] The current method of flue gas treatment is to introduce the flue gas into the reaction tower to filter the flue gas. However, some flue gas discharged from the chimney has a large volume, and the reaction tower cannot be directly installed on the chimney. When working, the reaction tower will produce more reaction sediments when it is working. The sediments and the reaction liquid are mixed together, which will reduce the filtering effect. When the flue gas enters the reaction tower, because the flue gas itself Diffusion movement, slow filtering speed of flue gas
