Backward flow type tail gas treatment device

Abstract

The invention relates to a backward flow type tail gas treatment device comprising a tail gas exhaust port. The backward flow type tail gas treatment device is characterized in that the tail gas exhaust port extends into a liquid tank; a plurality of layers of filter screens provided with a plurality of rows of transverse through grooves are arranged on the level part of the liquid tank; and the filter screens are arranged at intervals. Through introducing tail gas exhausted from boilers and other industrial process equipment to liquid, the invention can clean away large amount of dust, sulfide and other pollutants carried in the tail gas, thereby self filtering can be achieved without the need of external power.

Description

Technical field: [0001] The invention relates to a reverse irrigation type tail gas treatment device. Background technique: [0002] At present, all kinds of boilers are not only widely used in industry, but also more and more widely used in people's daily life. The emission of boiler tail gas is also a problem that people have been paying attention to. The exhaust filter is not clean, which will inevitably cause damage to nature The destruction of other harmful substances is not clean, and it will also cause damage to nature. Therefore, there are currently a large number of devices for exhaust gas purification treatment, such as a double-tower water spray exhaust gas purification treatment device. Although this device can achieve a certain filtering effect, it requires high-horsepower water spray power equipment, and the manufacturing cost is high. 1. Water pipes are often blocked; in addition, exhaust gas purification treatment devices such as drainage type and dry powder...

Problems solved by technology

[0002] At present, various boilers are not only widely used in industry, but also more and more widely used in people's daily life. The emission of boiler tail gas is also a problem that people have been paying attention to. The exhaust filter is not clean, which will inevitably cause damage to nature. The destruction of other harmful substances is not clean, and it will also cause damage to nature

Therefore, a large number of devices for exhaust gas purification have appeared at present, such as a double-tower water spray exhaust gas purification device. Although this device can achieve a certain filtering effect, it requires high-horsepower water spray power equipment, and the manufacturing cost is high. 1. Water pipes are often blocked; in addition, there are also exhaust gas purification treatment devices such as drainage type and dry powder type, which are likely to cause filter blockage and fail to work normally, and the dust removal is not thorough and difficult to clean.
