Chemical processing waste gas purification tower

Abstract

The invention relates to the technical field of factory waste gas purification, in particular to a chemical processing waste gas purification tower, which comprises a tower body, wherein a purifying agent chamber is arranged at the bottom end of the inner wall of the tower body, a filter screen is fixedly connected to the inner wall of the purifying agent chamber, a gas inlet pipe is fixedly connected to the outer surface of the purifying agent chamber, the side, close to the inner wall of the tower body, of the lower end of a fixing disc is fixedly connected with a liquid return pipe, one end of the liquid return pipe penetrates through the upper end of the fixing disc, the other end of the liquid return pipe penetrates through the upper end of a first-stage partition plate and communicates with the interior of the purifying agent chamber, a second-stage partition plate is fixedly connected to the position, located above the fixing disc, of the inner wall of the tower body, the lower end of the second-stage partition plate is fixedly connected with a spraying pipe, and the lower end of the spraying pipe is fixedly connected with a plurality of atomizing nozzles. According to the invention, by arranging the fixing disc, the exhaust of waste gas can be dispersed while a certain drainage effect can also be achieved on a purifying agent, so that the contact area between the waste gas and the purifying agent can be increased, the reaction effect can be improved, and the waste gas can be better subjected to acid-alkali neutralization treatment.

Description

technical field [0001] The invention relates to the technical field of factory waste gas purification, in particular to a chemical processing waste gas purification tower. Background technique [0002] Chemical processing waste gas refers to the toxic and harmful gas discharged from chemical plants in chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity. It seriously pollutes the environment and affects human health. [0003] The patent number is: CN202010719237.0 discloses a chemical processing exhaust gas purification tower, which includes a tank body, an air inlet is fixedly installed on the lower part of the outer surface of the tank body, and an air outlet is fixedly installed on the outer surface of the upper end of the tank body. The inner lower part of the tank body is fixedly equipped with a vertical filter screen, and the inner lower end of the tank body is located at the s...

Problems solved by technology

[0005] The purpose of the present invention is to provide a chemical processing waste gas purification tower, which mainly solves the problem that the equipment is bulky and the waste gas is introduced into the waste gas purification tower after pressurization, resulting in too fast flow rate, so that the gas-liquid contact time is short and the reaction effect is poor. The problem of not being able to neutralize the exhaust gas well
