It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0027] As Figure 1As shown, the utility model provides a kind of waterworks upper building air pollutant interception device, including frame, the inside of frame is provided with filter screen 8, the inside of frame is provided with flow channel, flow channel is provided with water inlet and multiple water outlets, water inlet is connected with water supply pipeline 5, water outlet is provided with spray nozzle 12, spray nozzle 12 is arranged on frame, spray nozzle 12 is used to spray water into mist in frame inside to form water mist net, filter screen 8 is used to filter impurity and limit water mist to spread to indoor, the bottom of frame is provided with water collecting groove, water collecting groove is used to recycle part water resource that spray nozzle 12 sprays, filter pad 7 is provided in water collecting groove, recycling opening is opened in water collecting groove, recycling opening is used to recycle water resource in water collecting groove.

[0028] The waterworks upper building air pollutant interception device can be installed in the ventilation and air exchange area of the waterworks building, such as window, ventilation shaft, etc., and can be installed through the mounting plate 4 at the four corners of the frame. The filter screen 8 is close to the inside of the waterworks building, and the spray nozzle 12 is close to the outside of the waterworks building. The spray nozzle 12 has a nozzle aperture of less than 0.1 mm, and 15-18 are distributed per meter. The spray nozzle 12 forms a uniform water mist net, and a double barrier is formed in combination with the filter screen 8. The water mist net can absorb part of the gaseous pollutants dissolved in water (such as sulfur dioxide SO2, nitrogen oxides NO x ) and block small impurities (such as PM2.5, PM10, dust, etc.). The filter screen 8 can block larger impurities, and part of the water mist can form a dynamic wet layer on the filter screen 8. The filter screen 8 itself forms a double barrier of "physical interception + wet filtration". The particulate matter is not easy to penetrate, further capturing particulate matter in the air and absorbing part of the gaseous pollutants dissolved in water, thereby greatly improving the interception efficiency. In addition, the filter screen 8 uses a dense mesh (such as a 2 mm aperture) to minimize the possibility of water mist spreading indoors, especially under the action of wind. Water droplets will flow down along the dense mesh instead of drifting with the airflow.

[0029] Therefore, the waterworks upper building air pollutant interception device of the utility model significantly reduces the particulate matter concentration entering the equipment interior through the wet deposition effect of the water mist net and the filter screen 8, improves the equipment stability, and the effect of the device is particularly obvious in severe weather conditions such as haze, dust, sandstorm, etc.

[0036] In some embodiments, the two ends of the column 1 are provided with magnets 9, and the magnets 9 attract and connect the column 1 and the cross bar.

[0037] It can be understood that the connection reliability of the column 1 and the cross bar can be further improved by arranging the magnets 9.

[0038] In some embodiments, part or all of the spray nozzles 12 on the column 1 spray in a direction away from the filter screen 8.

[0039] It can be understood that by spraying part or all of the spray nozzles 12 on the column 1 in a direction away from the filter screen 8, the influence of wind on the water mist can be reduced, and the water mist screen can be stably formed on one side of the filter screen 8.

[0046] In some embodiments, the filter screen 8 is detachably connected with the frame through magnetic attraction.

[0047] The way of connecting the filter screen 8 with the frame through magnetic attraction can be that a ring of magnets is arranged on the outer edge of the filter screen 8, and an extension plate is integrally arranged on the inner side of the column 1 and the cross bar, the extension plate being arranged close to the edge of the frame, the filter screen 8 being directly placed into the frame, and the magnets being attracted and fixed on the extension plate.
