Waste gas treatment device in airplane paint spraying process

Abstract

The invention provides a waste gas treatment device in an airplane paint spraying process. The waste gas treatment device comprises a paint spraying chamber, a paint spraying machine, a storage chamber, a paint spraying part detection mechanism, a waste gas conveying mechanism and a waste gas treatment mechanism. According to the waste gas treatment device, after an airplane is driven into the paint spraying chamber, the airplane is stopped in a stopping area of the paint spraying chamber, paint spraying personnel can move the paint spraying machine in the storage chamber to different paint spraying stations of the stopping area to spray paint on all parts of an airplane, the arranged paint spraying part detection mechanism can detect the paint spraying parts, and therefore waste gas conveying adjustment can be conducted through the waste gas conveying mechanism, the waste gas treatment mechanism comprises a UV photolysis box and an activated carbon adsorption box, the waste gas conveying mechanism can convey waste gas into the UV photolysis box or the activated carbon adsorption box according to different paint spraying parts of the airplane, different treatment modes are adopted for different waste gas, the waste gas treatment effect is guaranteed, air pollution is prevented, and the body health of paint spraying personnel is ensured.

Description

technical field [0001] The invention relates to the technical field of aircraft maintenance, in particular to an exhaust gas treatment device in the aircraft painting process. Background technique [0002] Spray painting refers to the coating method that is dispersed into uniform and fine mist droplets by means of pressure or centrifugal force through a spray gun or disc atomizer, and applied to the surface of the object to be coated. It is often used to paint furniture, automobile surfaces, aircraft surfaces, etc. The paint used for painting often contains a large amount of volatile toxic substances, such as methanol, ethanol, propanol, butanol, which are soluble in water, and benzene, toluene, xylene, etc. which are insoluble in water. Therefore, Most of the painting process is carried out in open factories, resulting in the direct discharge of toxic waste gas into the atmosphere, polluting the atmosphere, and not all of the toxic waste gas will be discharged into the outd...

[0002] Spray painting refers to the coating method that is dispersed into uniform and fine mist droplets by means of pressure or centrifugal force through a spray gun or disc atomizer, and applied to the surface of the object to be coated. It is often used to paint furniture, automobile surfaces, aircraft surfaces, etc. The paint used for painting often contains a large amount of volatile toxic substances, such as methanol, ethanol, propanol, butanol, which are soluble in water, and benzene, toluene, xylene, etc. which are insoluble in water. Therefore, Most of the painting process is carried out in open factories, resulting in the direct discharge of toxic waste gas into the atmosphere, polluting the atmosphere, and not all of the toxic waste gas will be discharged into the outdoor environment, and some toxic waste gas will still remain in the factory building. People who stay in the factory building for a long time will inhale toxic exhaust gas, which will affect the health of painting personnel

[0003] In order to ensure the health of the paint sprayers, most of the exhaust gas treatment machines are installed in the spray booths. However, most of the current exhaust gas treatment machines are used for small objects to be sprayed, such as furniture, cars, etc. For airplanes, their flight The environment of the aircraft is different from that of the land, and the speed per hour is quite different from that of a car, which results in different damages to various parts of the aircraft, which directly affects the differences in the paint materials used in the painting of various parts of the aircraft, such as the nose of the aircraft as the windward side, The middle part of the tail, the windward side of the wing, etc., in order to improve the wind resistance, the paint used is different from other parts, so the treatment method of harmful exhaust gas generated during painting is different from that used in other parts. The use of a single treatment method will cause harmful gases to still be discharged outdoors. For example, the exhaust gas treatment device of a kind of aircraft painting room whose publication number is CN204952608U and the exhaust gas treatment system in a kind of aircraft painting process whose publication number is CN209033116U only unify the exhaust gas. The treatment does not adopt different exhaust gas treatment methods according to the different parts of the aircraft spraying
