Embodiment Construction

[0018] As shown in the figure, the specific implementation method is as follows:

[0019] A dust removal device for an exhaust fan, comprising a large water tank 6, a first small water tank 2 and a second small water tank 4 are fixed on the top surface of the large water tank 6, the large water tank 6, the first small water tank 2 and the second small water tank The inner cavities of 4 communicate with each other and the three cooperate to form a concave-shaped structure. A first pipe 102 is connected to the side wall of the first small water tank 2, and a U-shaped pipe 1 is connected to the end of the first pipe 102 away from the first small water tank 2. , the other end of the U-shaped pipe 1 is connected with a second pipeline 101, the lowest point of the second pipeline 101 is higher than the highest point of the first pipeline 102, and the liquid level in the first small water tank 2 is higher than the highest point of the first pipeline 102 , the liquid level in the firs...

Abstract

The invention discloses a dust collection device for an exhaust fan. The dust collection device comprises a large water tank, wherein a first small water tank and a second small water tank are fixed on the top surface of the large water tank; a sludge cleaning device is arranged at the bottom of the large water tank. With the combination of a U-shaped tube and the large water tank and the small water tank, the effect that sealing is achieved to limit air in an exhaust fan air outlet from being directly discharged into the atmosphere is achieved, the air can be firstly introduced into water toform bubbles in the air, then the dust of discharged air can be removed, the air is further introduced into air after the dust is removed, then dust influence to the air is reduced, the haze degree isreduced, and haze treatment is facilitated.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device for an exhaust fan. Background technique [0002] Haze is a combination of fog and haze. Smog is common in cities. In many areas of China, fog is combined with haze as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "smog weather". Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. range of smog. The aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment called haze. Haze is haze (haze). [0003] Fog is an aerosol syst...
