Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and more specifically, to VOCs organic waste gas purification equipment. Background Art

[0002] Volatile organic compounds (VOCs) are a type of waste gas, organic chemicals with a high vapor pressure at room temperature. Exposure to VOCs may have various health effects. In addition, VOCs may also promote the formation of ground ozone and haze, which has an impact on the environment and health. Therefore, in order to reduce its pollution to the environment, it is usually necessary to treat it. However, traditional treatment devices have some shortcomings. For example, when treating organic waste gas, some existing devices mainly use porous media such as activated carbon and zeolite to adsorb odorous substances, among which activated carbon is the most widely used. Although this method is relatively simple and requires less one-time investment, the medium has a short service life (once saturated, it needs to be regenerated or even replaced), the treatment efficiency is unstable, and the treatment efficiency is low, resulting in poor results when treating waste gas with higher concentrations, resulting in incomplete waste gas treatment.

[0027] By setting up an annular ventilation pipe 44, a titanium dioxide mesh plate is set inside the annular ventilation pipe 44. After controlling the UV lamp tube 43 to produce a specific UV band, the titanium dioxide mesh plate produces strong oxidizing substances, hydroxyl groups and active oxygen in the annular ventilation pipe 44, and the VOCs organic waste gas in the annular ventilation pipe 44 is oxidized to form harmless gases such as carbon dioxide.

[0028] It also includes a biological treatment component 5 and an air outlet 6. The bottom of the biological treatment component 5 is fixedly installed on the top of the base plate 1, the end of the biological treatment component 5 is fixedly installed on the end of the connecting plate 42, and the side end of the air outlet 6 is fixedly installed on the side of the biological treatment component 5.

[0029] Among them, the pretreatment component 2 includes a first pillar 20, a first reaction box 21, a sealing cover 22, an activated carbon filter plate 23, and a connecting pipe 24. The bottom of the first pillar 20 is fixedly installed on the top of the base plate 1, the bottom of the first reaction box 21 is fixedly installed on the top of the first pillar 20, the side end of the sealing cover 22 is movably installed on the top of the first reaction box 21, the activated carbon filter plate 23 is arranged inside the first reaction box 21, the side of the activated carbon filter plate 23 is slidably installed on the inner surface of the first reaction box 21, the side end of the connecting pipe 24 is fixedly installed on the side of the first reaction box 21, and the top end of the connecting pipe 24 is fixedly installed on the end of the annular ventilation pipe 44.

[0030] The biological treatment component 5 includes a third pillar 50, a second reaction box 51, a connecting pipe 52, a biological filter plate 53, and a fan 54. The bottom of the third pillar 50 is fixedly installed on the top of the bottom plate 1, the bottom of the second reaction box 51 is fixedly installed on the top of the third pillar 50, one end of the connecting pipe 52 is fixedly installed on the end of the annular ventilation pipe 44, and the other end of the connecting pipe 52 is fixedly installed on the top of the second reaction box 51. The biological filter plate 53 is arranged inside the second reaction box 51, and the outer surface of the biological filter plate 53 is fixedly installed on the inner surface of the second reaction box 51. The bottom of the fan 54 is fixedly installed on the inner surface of the second reaction box 51, and the side end of the fan 54 is fixedly installed on the end of the air outlet 6.

[0031] By setting up the fan 54, during the VOCs organic waste gas treatment process, the staff can control the external injection pressure pump and the fan 54 to adjust and control the rate of the VOCs organic waste gas flowing through the pretreatment component 2, the photocatalytic treatment component 4, and the biological treatment component 5, so as to make the VOCs organic waste gas react more thoroughly.

[0032] The working process of the utility model is as follows:

[0033] First, the staff connects the VOCs organic waste gas to be treated to the air inlet 3. The VOCs organic waste gas is purified by the pretreatment component 2, the photocatalytic treatment component 4, and the biological treatment component 5 in sequence, and then discharged into the external environment through the air outlet 6;

[0034] When the VOCs organic waste gas is treated by the pretreatment component 2, the VOCs organic waste gas enters the interior of the first reaction box 21 through the air inlet 3, and then passes through two groups of activated carbon filter plates 23 with different filter pore spacings arranged in the first reaction box 21. The large particle impurities in the VOCs organic waste gas are adsorbed and filtered out by the activated carbon filter plates 23, and the activated carbon filter plates 23 can also adsorb some harmful gases in the waste gas to a certain extent. In addition, after opening the sealing cover 22, the staff can extract the saturated activated carbon filter plate 23 from the first reaction box 21, and insert a new activated carbon filter plate 23 along the limit strip, which is conducive to the rapid replacement of the activated carbon filter plate 23, thereby improving the treatment efficiency of the VOCs organic waste gas. After that, the pretreated VOCs organic waste gas enters the interior of the photocatalytic treatment component 4 through the connecting pipe 24 for subsequent treatment;

[0035] When the VOCs organic waste gas is treated by the photocatalytic treatment component 4, the VOCs organic waste gas flows evenly along the inner surface of the annular ventilation pipe 44. At the same time, the staff can start the UV lamp 43. Since the annular ventilation pipe 44 is made of transparent material and a portion of titanium dioxide mesh is evenly arranged inside the annular ventilation pipe 44, the UV lamp 43 catalytically oxidizes the organic waste gas by using the photocatalyst titanium dioxide and ultraviolet light under the ultraviolet irradiation of the set band, and decomposes it into harmless substances, such as water and carbon dioxide and other harmless gases, so that various organic volatile compounds, including complex mixtures, can be effectively degraded. Compared with traditional filtering devices, the photocatalytic equipment has higher processing efficiency and wider applicability;

[0036] When the VOCs organic waste gas is treated by the biological treatment component 5, the harmless gases such as carbon dioxide formed after the treatment in the annular ventilation pipe 44 and the mixed VOCs organic waste gas mixture that has not been treated are input into the interior of the second reaction box 51 through the connected connecting pipe 52, and pass through the biological filter plate 53 from top to bottom. The cultured microorganisms inside the biological filter plate 53 come into contact with the VOCs organic waste gas. The microorganisms use the VOCs organic waste gas as a carbon source for growth and metabolism, thereby decomposing the VOCs organic waste gas into harmless substances such as carbon dioxide and water. Because the microorganisms can continue to grow and metabolize, they can maintain a high efficiency even in long-term operation, and the treatment of VOCs organic waste gas is durable.
