Description

TECHNICAL FIELD

[0001] The utility model relates to the field of waste gas treatment for paint spraying, and particularly relates to a waste gas treatment equipment for paint spraying. BACKGROUND

[0002] Most of the waste gas treatment equipment in the past does not have the function of monitoring the quality of waste gas in real time, and the operator can only roughly judge the treatment effect by observing the appearance, odor, etc. of the finally discharged waste gas after the equipment runs for a period of time, or waits for the environmental protection department to understand whether it meets the standard. This way of after-the-fact judgment makes it difficult to trace the source of the problem and take effective measures to adjust once the waste gas treatment does not meet the standard.

[0003] In the process of paint spraying, if the spray gun fails to cause the paint atomization effect to deteriorate, the concentration of pollutants in the generated waste gas increases significantly, and the operator cannot discover it in time, and the equipment still runs according to the original setting, which will eventually lead to a large amount of waste gas that does not meet the standard being discharged into the atmosphere, causing environmental pollution, and also possibly causing the equipment to fail due to long-term treatment of high-concentration pollutants, shortening the service life of the equipment.

[0032] The exhaust gas enters the device through the air inlet 2, which is usually connected with the paint spraying area to ensure that the exhaust gas can be timely sucked into the treatment. After the exhaust gas enters the shell 1, it first enters the cavity one 30. In the cavity one 30, the exhaust gas first passes through the first filter plate 32 for preliminary filtration. The first filter plate 32 is made of metal mesh or fiber material and is used to remove large particle impurities in the exhaust gas. The inner side wall of the cavity one 30 is provided with an air quality sensor 33 for real-time monitoring of the quality of the exhaust gas.

[0039] Working principle: please refer to Figures 1-5As shown, the paint spraying waste gas treatment equipment is used for effectively treating the waste gas generated in the paint spraying process, and ensures that the discharged gas meets the environmental protection standard. First, the waste gas enters the equipment through the air inlet 2. The air inlet 2 is usually connected with the paint spraying area, so as to ensure that the waste gas can be inhaled and treated in time. After the waste gas enters the shell 1, it first enters the cavity one 30. In the cavity one 30, the waste gas first passes through the first filter plate 32 for preliminary filtration. The first filter plate 32 is made of metal mesh or fiber material, which is used for removing large particle impurities in the waste gas. The inner side wall of the cavity one 30 is provided with an air quality sensor 33, which is used for monitoring the quality of the waste gas in real time. If the concentration of harmful substances in the waste gas exceeds the preset threshold value, the electric air control valve two 35 will be opened, so that the waste gas continues to enter the cavity two 37 for reprocessing and filtration by the second filter plate 39. In the cavity two 37, the waste gas passes through the second filter plate 39 for deep purification. The second filter plate 39 is made of finer filter material, such as high efficiency particulate air (HEPA) filter screen, so as to remove small particles and harmful gas components in the waste gas.

The filter plate 42 is made of activated carbon material, which has excellent adsorption capacity and can further adsorb residual harmful substances in the waste gas. The air permeable holes formed in the filter plate 42 ensure that the waste gas can pass through smoothly, and at the same time ensure sufficient contact area for the activated carbon to adsorb harmful substances. The waste gas treated by multiple purification processes finally enters the air outlet 5 through the reserved port 43. The corresponding relationship between the reserved port 43 and the air outlet 5 ensures that the waste gas can be smoothly discharged from the equipment. The air outlet 5 is usually connected with the external environment, so as to ensure that the purified waste gas can be safely discharged into the atmosphere, and at the same time, the filter member 4 is installed in the plug-in mode, which is convenient for later disassembly, installation and cleaning.
