Description

Technical Field

[0001] The utility model relates to the technical field of air supply and exhaust devices, in particular to a segmented air supply and exhaust device for a paint room. Background Art

[0002] Spraying longer workpieces requires a longer spray booth. Spraying requires a vertical airflow velocity of approximately 0.3 m / s across the work surface to ensure smooth and timely removal of paint mist. However, maintaining this airflow velocity throughout the entire spray booth requires a significant amount of air. The segmented air supply solution is based on the fact that spraying longer workpieces is performed in sections. By achieving a wind speed of 0.3 m / s in the work area and three air changes per hour in other areas, we can reduce equipment investment, operating costs, and VOC emissions.

[0003] At present, the common paint room air supply and exhaust devices have high energy consumption, high operating costs, and large VOC emissions, which are difficult to meet market demand. Therefore, we propose a paint room segmented air supply and exhaust device. Utility Model Content

[0028] In actual application: the paint room segmented air supply and exhaust device of the utility model is divided into N areas with a length of less than 3 meters along the length direction according to the length of the paint spraying room, and a number of upper air doors 3 are provided on the air supply pipe, and a number of lower air doors 7 are provided on the exhaust duct 8. The air doors of the working area and one area in front and behind of each spraying operation are opened (three on the upper and lower areas), and the air doors of other areas are closed. We define the working area of painting and the front and rear areas as working sections; fresh air is transported by the blower 1, through the air supply pipe 2 and the upper air door 3, to the static pressure chamber 4 of the working section, and is sent to the working section through the high-efficiency filter cotton 5. The clean air discharges the paint mist from top to bottom, and the exhaust gas passes through the grille 6, the lower air door 7 of the exhaust duct and the exhaust duct 8, and is sent to the exhaust duct 10 through the exhaust fan 9 for high-altitude discharge. During the painting operation, the supply and exhaust air of each section can be freely replaced according to different painting areas. The air volume configuration of this design only needs to meet the wind speed and air volume requirements of the painting area. The required fan power can be greatly reduced compared to ordinary paint rooms. Without affecting the operation, the equipment investment is reduced, and the operating costs are also reduced.
