Filtering device for waste gas

Abstract

The invention discloses a filtering device for waste gas. The filtering device comprises a waste gas conveying pipe, wherein a waste gas filtering mechanism is arranged on the outer surface of one endof the waste gas conveying pipe. According to the filtering device for the waste gas, through the arrangement of a waste gas filtering box, a polyester fiber filtering net, a filtering cotton net andan activated carbon filtering net, impurities in the waste gas can be filtered out, and filtering effect is good; through the arrangement of a connecting pipe, a machine shell, a motor, a rotating shaft, a draught fan, a spraying filtering box, a water tank, a sodium hydroxide absorption liquid conveying pipe, a water pump, a liquid outlet pipe and a spraying pipe, waste gas purification is facilitated; through the arrangement of a water purification box, a water injection opening, purified water and a water discharging opening, secondary purification of the purified waste gas is facilitated,and purification efficiency is improved; and through the arrangement of a deodorization filter box, an ozone generator and an exhaust port, residual odor in the waste gas can be filtered, so the purpose of protecting the environment is achieved, and the device can be conveniently used by people.

Description

technical field [0001] The invention relates to the technical field of exhaust gas filtration, in particular to a filter device for exhaust gas. Background technique [0002] Exhaust gas refers to the toxic and harmful gases emitted by human beings in the process of production and life, especially the production and emission of domestic waste gas from chemical plants, steel plants, pharmaceutical factories, coking plants and oil refineries, and human life. The smell is big, seriously pollutes the environment and affects human health, and the filter device for filtering waste gas cannot meet people's needs. [0003] There are certain drawbacks in the use of the existing filter devices. First of all, in the process of use, the existing filter devices have poor filtering effect and cannot completely filter the exhaust gas, which is not conducive to environmental protection. Moreover, the existing filter devices cannot filter the exhaust gas. The purification of the odor in the...

[0002] Exhaust gas refers to the toxic and harmful gases emitted by human beings in the process of production and life, especially the production and emission of domestic waste gas from chemical plants, steel plants, pharmaceutical factories, coking plants and oil refineries, and human life. The smell is big, seriously pollutes the environment and affects human health, and the filter device for filtering exhaust gas cannot meet people's needs

[0003] There are certain drawbacks in the use of the existing filter devices. First of all, in the process of use, the existing filter devices have poor filtering effect and cannot completely filter the exhaust gas, which is not conducive to environmental protection. Moreover, the existing filter devices cannot filter the exhaust gas. The purification of the odor in the waste gas has brought certain adverse effects to people's use process. Therefore, we propose an environmental protection equipment for waste gas filtration
