Cleaning method of exhaust gas mixed with dust

Abstract

The invention relates to the field of environmental protection equipment, and specifically discloses a method for cleaning waste gas mixed with dust; a cleaning device is used for cleaning, and the cleaning device includes a frame, a water tank, a stirring mechanism and an air intake mechanism, and a water outlet is provided at the lower part of the water tank , a liquid inlet pipe is fixed on the frame; the air inlet mechanism includes an air inlet pipe, a rotating shaft and a helical blade, the air inlet pipe is fixed to the water tank, the rotating shaft is arranged along the length direction of the air inlet pipe, a fixing piece is arranged on the outer periphery of the rotating shaft, and a first cone is fixed on the rotating shaft The gear and the rotating blade, the helical blade is located on the outer periphery of the rotating shaft, and the helical blade is connected with the rotating shaft key; the stirring mechanism includes the stirring shaft and the stirring blade, the upper end of the stirring shaft is connected to the frame in rotation, the second bevel gear is fixed at the lower end of the stirring shaft, and the stirring blade is fixed on the on the stirring shaft; the cleaning method includes the following steps: (1) preparing a cleaning solution; (2) filtering; (3) cleaning; (4) changing the liquid; (5) draining the liquid. This scheme can avoid the clogging of the intake pipe.

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.
