Description

TECHNICAL FIELD

[0001] The utility model relates to the field of waste gas treatment especially relates to a atmospheric pollution prevention and control spraying equipment. BACKGROUND

[0002] With the acceleration of industrialization, the problem of air pollution is increasingly serious. Industrial waste gas emission is one of the main sources of air pollution, containing various complex pollutants, such as volatile organic compounds, sulfur dioxide, nitrogen oxides, particulate matter, etc. These pollutants not only damage air quality, but also pose a serious threat to the ecological environment and human health. For example, sulfur dioxide and nitrogen oxides are key factors in the formation of acid rain, and organic compounds can cause photochemical smog, while inhalable particulate matter can directly enter the respiratory system and cause respiratory diseases and even cardiovascular diseases.

[0003] The traditional atmospheric pollution prevention and control spraying equipment only has the basic function of capturing particulate matter in waste gas and settling with the spraying liquid through spraying liquid spraying. Although it can purify waste gas to some extent, it also has many limitations. First, when spraying and purifying waste gas inside the spraying tower, the concentration distribution of waste gas at different heights in the spraying tower may be different. The spraying head cannot adjust the spraying according to waste gas of different concentrations, which reduces the removal efficiency of pollutants. It is difficult to adjust according to the actual distribution of waste gas, and it cannot ensure that waste gas is uniformly mixed with spraying liquid inside the spraying tower, which reduces the effect of waste gas purification.

[0004] Secondly, the particulate matter, fibers and other impurities in the waste gas will enter the spraying tower with the waste gas, directly blocking the spraying head, causing uneven spraying, making some areas in the spraying tower unable to be effectively sprayed and treated, and affecting the overall purification effect.

[0005] In addition, high-temperature waste gas directly entering the spraying tower will cause the temperature of the spraying liquid to rise, resulting in a decrease in the absorption capacity of the absorbent, affecting the absorption efficiency of pollutants such as sulfur dioxide and nitrogen oxides in the waste gas, and making it difficult for the purified waste gas to meet the emission standards.

[0006] In summary, the existing atmospheric pollution prevention and control spraying equipment has deficiencies in spraying effect and filtering effect, and cannot meet the demand for purifying waste gas. Therefore, it is of great practical significance to develop an atmospheric pollution prevention and control spraying equipment that can adjust the height of the spraying head according to the actual distribution of waste gas, more specifically treat high-concentration waste gas, improve the removal efficiency of pollutants, and ensure that waste gas is uniformly mixed with spraying liquid inside the spraying tower, improving the efficiency of waste gas purification.
