Device for cleaning inner wall of oil-stain-containing waste gas exhaust pipeline

Abstract

The invention discloses a device for cleaning the inner wall of an oil stain-containing waste gas exhaust pipeline, and belongs to the field of waste gas treatment. According to the scheme of the device for cleaning the inner wall of the oil stain-containing waste gas exhaust pipeline, when oil stain-containing waste gas is exhausted from the interior of an exhaust pipeline, the interior of a high-temperature-resistant rubber air bag expands to extrude a fixed block out of the inner wall of a cleaning hole, then a cleaning ring rolls on the inner wall of the exhaust pipeline through balls, andsoap is brought out to the inner wall of the exhaust pipeline through the balls to decompose oil stains; a shape memory filter screen in the cooling pipe deforms when heated; the height of the cleaning ring in the exhaust pipeline is controlled through the temperature, and anti-freezing solution in the cooling pipe cools high-temperature waste gas to reduce damage to the cooling pipe; noise generated when the waste gas is exhausted is effectively reduced through cold noise elimination holes and a noise elimination layer in the cooling pipe, so that noise pollution to the surrounding environment is reduced; and metal particles in the waste gas are adsorbed through the noise elimination holes, and pollution of the metal particles to the environment is reduced.

Description

Technical field [0001] The invention relates to the field of waste gas treatment, and more specifically, to a cleaning device for the inner wall of an oily waste gas discharge pipe. Background technique [0002] Exhaust gas treatment should be carried out from two aspects: one is to remove dust from suspended particulate pollutants; the other is to purify gaseous pollutants. The control of gaseous pollutants mainly uses physical and chemical properties, such as solubility, adsorption saturation, dew point and selective chemistry Differences in reaction, etc., separate pollutants from exhaust gas; or transform pollutants into harmless or easy-to-treat substances. The basic methods of exhaust gas purification include absorption, adsorption, condensation, catalytic conversion and combustion, etc. . [0003] Overview of air pollution control technology. Air pollution control technology is an important countermeasure for atmospheric environmental protection. Clean combustion technology...

AI Technical Summary

Problems solved by technology

[0005] When exhausting, some oil stains and particles are easy to adhere to the inner wall of the pipeline, which will cause serious corrosion on the inner wall of the pipeline for a long time, which will reduce the service life of the pipeline, and the discharged exhaust gas contains a large amount of pollutants, which is easy to cause serious impact on the environment
