A chemical tail gas purification device with self-cleaning function

Abstract

The invention discloses a chemical tail gas purification device with self-cleaning function, comprising a chemical tail gas absorption pool and a chemical tail gas purification tower, the upper part of the chemical tail gas absorption pool is connected to the chemical tail gas purification tower, and one end side wall of the chemical tail gas absorption pool is inserted into the tail gas The input pipe, and one end of the exhaust gas input pipe is connected with the first corrosion-resistant pump. The brush moves continuously to scrape off the exhaust gas impurity particles attached to the surface of the second activated carbon filter layer and fall onto the slope plate. The impurity particles are washed into the filter box, and then filtered by the filter, so that the dry exhaust gas impurity particles are stored in the filter box, achieving the function of self-cleaning the second activated carbon filter layer, ensuring the continuous production in the future, and maintaining the second activated carbon filter The self-cleaning of the layer ensures the normal absorption efficiency and effect of the back.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a chemical tail gas purification device with self-cleaning function. Background technique [0002] In the preparation of chemical products in the prior art, a lot of tail gas will be produced during the manufacturing process from raw materials to finished products, which are generally directly discharged to cause environmental pollution. At present, the tail gas absorption generally adopts one-stage or multi-stage falling film absorption tower, which can absorb harmful substances and dust in the tail gas. This device absorbs and utilizes the tail gas in the chemical production process, but when it absorbs to a certain extent, The internal mesh will adhere to a lot of exhaust dust particles, causing blockage, which will affect the subsequent continuous production. It is difficult to ensure the normal absorption efficiency and effect of the latter. It is necessary to regularly disa...

[0002] In the preparation of chemical products in the prior art, a lot of tail gas will be produced during the manufacturing process from raw materials to finished products, which are generally directly discharged to cause environmental pollution. At present, the tail gas absorption generally adopts one-stage or multi-stage falling film absorption tower, which can absorb harmful substances and dust in the tail gas. This device absorbs and utilizes the tail gas in the chemical production process, but when it absorbs to a certain extent, The internal mesh will adhere to a lot of exhaust dust particles, causing blockage, which will affect the subsequent continuous production. It is difficult to ensure the normal absorption efficiency and effect of the latter. It is necessary to regularly disassemble and clean the internal filter mesh of the absorption tower, but man-made Cleaning the inside of the absorption tower will be time-consuming and labor-intensive
