Problems solved by technology
When the exhaust gas treatment equipment shuts down, it is found on the site that the leeward side of the runner away from the filter bag will have an influx of wind to the runner, and the residual paint particles carried by the wind will pollute the runner, causing the runner to block and cause safety hazards. Hidden dangers, resulting in a shorter service life of the runner, and in severe cases, the runner needs to be replaced, causing serious economic losses

The invention discloses a waste gas treatment system and a control method thereof, and belongs to the technical field of automobile coating. The waste gas treatment system comprises a spray booth which is provided with an air inlet in a first side wall and an air outlet in a second side wall; a waste gas treatment device which comprises a box body positioned in the spray booth, and a filtering assembly and a rotating wheel which are respectively positioned in the box body; a backflow filtering device which comprises a horizontal driving piece arranged at the bottom of the spray booth, a vertical driving piece connected to the horizontal driving piece, a filtering box connected to the vertical driving piece, and a filter located in the filtering box; and a controller which is used for controlling the horizontal driving piece and the vertical driving piece to act when it is determined that a waste gas treatment device in the spray booth is shut down or the filtering assembly needs to be replaced, so that backward flowing wind is filtered through the filter. The probability that the rotating wheel is blocked and has potential safety hazards due to backward flowing of air can be reduced, the service life of the rotating wheel is prolonged, and economic losses caused by rotating wheel replacement are avoided.
Description
technical field [0001] The invention relates to the technical field of automobile painting, in particular to an exhaust gas treatment system and a control method thereof. Background technique [0002] The painting of vehicles is usually carried out in the spray booth. In order to prevent the paint mist exhaust from polluting the environment, the paint mist exhaust is usually treated by exhaust gas treatment equipment and then discharged. [0003] In the prior art, the exhaust gas treatment equipment includes a filter bag and a runner located downstream of the filter bag. After being filtered by the filter bag, the paint mist exhaust gas needs to be further filtered through the runner. During the operation of the waste gas treatment equipment, there will be equipment failure or replacement of filter bags. Equipment failures include RTO gas system or valve failures. At this time, the waste gas treatment equipment needs to be shut down and the processing of paint mist waste gas...
