A waste gas purifier for chemical and pharmaceutical industries

Abstract

The invention discloses a waste gas purifier for chemical and medicine industries. The waste gas purifier comprises a body and a water storage pond, wherein a gas inlet is formed in the upside of the body; a gas inlet valve is arranged on the gas inlet; a filter chamber is connected to the downside of the gas inlet; the filter chamber is connected with a gas inlet pipe through a main pipe, a plurality of pores are formed in the surface of the gas inlet pipe, an oil filtering plate is arranged inside the body; a filtering layer is arranged below the oil filtering plate, the water storage pond is a closed cavity and is arranged below the body, filtering water is contained in the water storage pond, a funnel is arranged at the lower part of the body, the lower end of the funnel penetrates through the top wall of the water storage pond and is inserted to be under the liquid level in the water storage pond, a gas outlet pipe is arranged at the lower part of the body, a gas outlet valve is arranged on the gas outlet pipe, a pipe opening of the gas outlet pipe penetrates through one side of the top wall of the water storage pond and is inserted into a cavity at the upper part of the water storage pond, and the height of the pipe opening of the gas outlet pipe, inserted into the water storage pond, is greater than that of the liquid level in the water storage pond. The waste gas purifier has the advantages of reasonable structure design, good purifying effect, long service life and the like.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an exhaust gas purifier for chemical and pharmaceutical industries. Background technique [0002] At present, industrial waste gas is a major source of pollution. Various toxic and harmful gases contained in industrial waste gas have caused great pollution to the environment, such as sulfur dioxide and hydrogen sulfide, and some particulate matter has caused serious air pollution to the public environment. And as one of the main sources of air pollution, industrial waste gas has a great destructive effect on the living environment of human beings. Therefore, it is very important to effectively treat industrial waste gas so that it can meet the appropriate emission requirements before entering the atmospheric environment. Important practical significance, the Chinese patent document CN201420293216.7 discloses an industrial waste gas purifier, which is composed of an air inlet pipe,...

[0002] At present, industrial waste gas is a major source of pollution. Various toxic and harmful gases contained in industrial waste gas have caused great pollution to the environment, such as sulfur dioxide and hydrogen sulfide, and some particulate matter has caused serious air pollution to the public environment. And as one of the main sources of air pollution, industrial waste gas has a great destructive effect on the living environment of human beings. Therefore, it is very important to effectively treat industrial waste gas so that it can meet the appropriate emission requirements before entering the atmospheric environment. Important practical significance, the Chinese patent document CN201420293216.7 discloses an industrial waste gas purifier, which is composed of an air inlet pipe, an air outlet pipe and a spray head. The impurities in the exhaust gas are settled by the spray head, and then the gas passes through the second filter body and the third filter body to purify the exhaust gas. However, this structural design is relatively simple and cannot completely purify the impurities contained in the exhaust gas. After filtering, the exhaust gas still contains impurities. It has not been removed, which not only reduces the work efficiency, but also cannot completely purify the impurities contained in the exhaust gas.
