Air conversion purification device for chimney

Abstract

The invention discloses an air conversion purification device for a chimney. The device comprises a purification tank, wherein a partition plate is fixedly arranged in the position, close to the bottom end, of the inside of the purification tank, a steel wire mesh cage is arranged at the bottom of the partition plate, activated carbon bags are arranged in the steel wire mesh cage, a smoke inlet pipe is arranged on the left side wall of the purification tank and abuts against the bottom of the partition plate, a dust fall device is arranged above the partition plate in the purification tank, arectangular through groove is formed in the outer side of the upper port of the purification tank in a sleeving manner, and the bottom end of the rectangular through groove is fixedly connected with the top end of the purification tank through screws. In the actual use process, smoke from the chimney enters the purification tank from the smoke inlet pipe, is located below the partition plate, andis evenly emitted from circular through holes in the partition plate, at the moment, a spraying device sprays lime water downwards to spray down solid particles in part of the smoke, and the part of the smoke is adsorbed by rotating twisted ropes. The device not only can remove solid shells in the smoke, but also can remove acid gas in the smoke by lime water, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of air conversion and purification devices, in particular to an air conversion and purification device for chimneys. Background technique [0002] For the waste gas produced in the production process of chemical plants, the content of harmful substances must reach the standard before it can be discharged. The current chimney waste gas purification device mainly treats the flue gas in two aspects, one is the treatment of solid particles in the flue gas, and the other is the flue gas However, it still has the following disadvantages in actual use: [0003] 1. In the prior art, when removing the acidic substances in the flue gas, the flue gas is mostly passed directly into the lime water. This method makes the contact area between the flue gas and the lime water small, so the acidic substances cannot be completely removed; [0004] 2. For the removal of solid particles, dust-removing cloth bags are mostly used...

AI Technical Summary

Problems solved by technology

[0003] 1. In the prior art, when removing the acidic substances in the flue gas, the flue gas is mostly directly passed into the lime water. This method makes the contact area between the flue gas and the lime water small, so the acidic substances cannot be completely removed;

[0004] 2. For the removal of solid particles, most of the existing technologies use dust-removing cloth bags to remove them, but the installation of dust-removing cloth bags is mostly inconvenient to disassemble, and the dust-removing effect is poor
