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 make people feel uncomfortable in the rainy season with high humidity; third, the washing water used for spraying is often ordinary tap water, which is not suitable for For water that contains more minerals, the spray will force the water to evaporate, causing the minerals in the water to become fine dust particles in the air, which will increase the concentration of indoor particles

Embodiment 1

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

Embodiment 2

[0022] Take 4 brush rollers with a diameter of 5cm, and the length of the bristles is 2cm, according to figure 1 The method shown is installed in a box. The two sides of the brush rollers are close to the box to avoid gas leakage. The two brush rollers on the upper layer rotate counterclockwise, while the two brush rollers on the lower layer rotate clockwise. The adjacent brush rollers The bristles of the rollers overlap each other to a depth of 1 cm. Fill the water tank with 1% cetyltrimethylammonium bromide aqueous solution. The liquid level just submerges the lower bristles of the lower brush roller, and the gas baffle is inserted into the first bristle 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 an air intake fan, a spray pump and a spray pipe.

Embodiment 3

[0024] Take 8 brush rollers with a diameter of 20cm and a bristle length of 7cm, according to figure 1 The method shown is installed in a box. The two sides of the brush rollers are close to the box to avoid gas leakage. The 4 brush rollers on the upper layer rotate counterclockwise, while the 4 brush rollers on the lower layer rotate clockwise. The adjacent brush rollers The bristles of the rollers overlap each other to a depth of 1.4cm. Fill the water tank with 1% dibromohydantoin aqueous solution. The liquid level just submerges the lower bristles of the lower brush roller. The depth of the gas baffle inserted into the first brush roller on 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...
