Method for cleaning dust-mixed waste gas

Abstract

The invention relates to the field of environment-protecting equipment, and particularly discloses a method for cleaning dust-mixed waste gas. A cleaning device is used for cleaning and comprises a machine frame, a water tank, a stirring mechanism and a gas inlet mechanism; a water outlet is formed in the lower part of the water tank; a liquid inlet pipe is fixed on the machine frame; the gas inlet mechanism comprises a gas inlet pipe, a rotating shaft and a spiral blade; the gas inlet pipe is fixed with the water tank; the rotating shaft is arranged in the length direction of the gas inlet pipe; a fixed piece is arranged at the periphery of the rotating shaft; a first bevel gear and a rotating blade are fixed on the rotating shaft; the spiral blade is positioned at the periphery of the rotating shaft; the spiral blade is connected with a rotating shaft key; the stirring mechanism comprises a stirring shaft and a stirring blade; the upper end of the stirring shaft is rotatably connected with the machine frame; a second bevel gear is fixed at the lower end of the stirring shaft; the stirring blade is fixed on the stirring shaft. The cleaning method comprises the following steps: (1)preparing a cleaning liquid; (2) filtering; (3) cleaning; (4) changing the liquid; (5) discharging the liquid. According to the scheme, blockage of the gas inlet pipe can be avoided.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a gas cleaning device. Background technique [0002] The current factories will generate waste gas during the production process. These waste gases contain a large amount of toxic and harmful gases and dust with different particle sizes. Great damage to people's health, so it is necessary to purify the exhaust gas before discharging it. [0003] The traditional purification method is to filter the gas to remove relatively large dust in the exhaust gas; then add the reagent to water to form a solution, and pass the exhaust gas into the solution, the toxic and harmful gas contacts the solution and reacts with the reagent, so that it can be removed Toxic and harmful gases in the exhaust gas. However, dust with a smaller particle size needs a filter with a larger mesh to filter, and a filter with a larger mesh has a better blocking effect on exhaust gas, and the ti...

AI Technical Summary

Problems solved by technology

However, dust with a smaller particle size needs a filter with a larger mesh to filter, and a filter with a larger mesh has a better blocking effect on exhaust gas, and the time for exhaust gas to pass through the filter increases, and the efficiency will be further reduced

However, if the waste gas is directly passed into the solution, the dust in the waste gas will adhere to the pipe leading into the waste gas, the air intake of the pipe will be reduced, and the pipe will be easily blocked after long-term use.
