Problems solved by technology

This method is very similar to the process of rainfall and haze elimination in the natural atmosphere, but its disadvantages are also very obvious: first, this method needs to use nozzles, liquid or gas with a certain pressure, which will bring additional equipment investment and bring Second, this method will cause the problem of "over-humidification" of the indoor air, which will

Example Embodiment

[0019] Example 1:

[0020] Take 6 brush rollers with a diameter of 30cm and the length of the bristles is 10cm. figure 1 The way shown is installed in a box, the brush rollers are close to the box on both sides to avoid gas leakage, the upper 3 brush rollers rotate counterclockwise, and the lower 3 brush rollers rotate clockwise, adjacent to the brush rollers. The bristles of the rollers overlap each other to a depth of 2mm. Pay attention to the 1% aqueous solution of benzalkonium bromide in the water tank. The liquid level just submerges the lower bristles of the lower brush roller. The depth of the gas baffle inserting the first brush roller of the upper layer is 2cm. , the high-efficiency gas dust removal and purification device is obtained after installing the intake fan, the spray pump and the spray pipe.

Example Embodiment

[0021] Example 2:

[0022] Take 4 brush rollers with a diameter of 5cm, and the length of the bristles is 2cm. figure 1 The way shown is installed in a box, the two sides of the brush roller are close to the box to avoid gas leakage, the upper two brush rollers rotate counterclockwise, while the lower two brush rollers rotate clockwise, and the adjacent brush rollers rotate counterclockwise. The bristles of the roller overlap each other at a depth of 1cm. Pay attention to the 1% cetyltrimethylammonium bromide aqueous solution in the water tank. The liquid level just submerges the lower bristles of the lower brush roller, and the gas baffle is inserted into the first bristles of the upper layer. The depth of the brush roller is 1cm, and the high-efficiency gas dust removal and purification device is obtained after installing the air intake fan, the spray pump and the spray pipe.

Example Embodiment

[0023] Example 3:

[0024] Take 8 brush rollers with a diameter of 20cm and a bristle length of 7cm. figure 1 The way shown is installed in a box, the brush rollers are close to the box on both sides to avoid gas leakage, the upper 4 brush rollers rotate counterclockwise, while the lower 4 brush rollers rotate clockwise, and the adjacent brushes The bristles of the rollers overlap each other at a depth of 1.4cm. Pay attention to the 1% dibromohydantoin aqueous solution in the water tank. The liquid level just submerges the lower bristles of the lower brush roller. The depth of the gas baffle inserting the first brush roller of the upper layer is 3cm, the high-efficiency gas dust removal and purification device is obtained after installing the intake fan, spray pump and spray pipe.

Abstract

The invention provides a rolling brushing type gas dust-removing purification device and belongs to the technical field of dust removal, indoor air management and environment protection. According to the device, two layers of hairbrush rollers which are arrayed in parallel and are overlapped are adopted; the upper and lower layers of the hairbrush rollers rotate in opposite directions; bristles at the lower part of the lower-layer hairbrush roller is immersed into a water tank; bristles of the upper-layer hairbrush roller is wetted by spraying water; dust-containing gas flows through a gap between the bristles of the hairbrush rollers; and dust particles are washed by the bristles to be removed. The device has low gas resistance and a simple structure, and is very suitable for indoor air purification.

Description

technical field [0001] The invention relates to a rolling brush type gas dust removal and purification device, which belongs to the technical fields of dust removal, indoor air treatment and environmental protection. Background technique [0002] With the rapid development of my country's economy, the haze air pollution in large and medium-sized cities, economically developed areas and areas with intensive basic industries in my country is becoming more and more serious. As my country's restrictions on SOx and NOx emissions become increasingly strict, and related environmental protection technologies and devices continue to be put into use, the increase in the total emission of SOx and NOx pollutants in my country's atmospheric environment has slowed down. However, from the current monitoring results, my country's long-term The smog pollution in the Delta, Pearl River Delta, and Beijing-Tianjin-Hebei areas has become increasingly serious, which has seriously threatened the he...
