Tail gas filtering device

Abstract

The invention provides a tail gas filtering device and belongs to the technical field of tail gas filtration. The tail gas filtering device comprises a filtering casing, a gas inlet pipe and a gas outlet pipe, wherein the gas inlet pipe and the gas outlet pipe are both arranged on the filtering casing, a filtering cavity is formed in the filtering casing, a partition board is arranged in the filtering cavity and divides the filtering cavity into a gas inlet cavity and a gas outlet cavity, a gas inlet port connected with the gas inlet pipe is formed in the gas inlet cavity, a gas outlet port connected with the gas outlet pipe is arranged in the gas outlet cavity, a gap exists between the lower end of the partition board and the bottom of the filtering cavity, a filtering liquid is containedat the bottom of the filtering cavity, a guide plate for one-way circulation of tail gas is arranged in the gas inlet cavity, a hydrodynamic wheel is arranged in the filtering liquid, a drive motor is arranged at the outer end of the filtering casing, an output shaft of the drive motor penetrates through the filtering casing and is connected with the hydrodynamic wheel, an outer end of the gas outlet pipe is connected with a fan, an air outlet of the fan is connected with an air outlet pipe, and a filtering layer is also arranged in the gas outlet cavity. Filtrating of the tail gas is accelerated, and the filtering effect on the tail gas is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of filtration and relates to an exhaust gas filtration device. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the factory area. In industrial production, waste gas will inevitably be produced, and if these waste gases are discharged into the air without treatment, they will definitely have an impact on the environment. [0003] With the gradual strengthening of environmental protection awareness, enterprises will filter and discharge waste gas when discharging waste gas. However, the existing filter devices are relatively simple. The filter device generally includes a filter layer, and the waste gas is screened and filtered through the filter layer. The filtering effect is poor, and the particles contained in the exhaust gas will block the filter layer, causing ...

[0003] With the gradual strengthening of environmental protection awareness, enterprises will filter and discharge waste gas when discharging waste gas. However, the existing filter devices are relatively simple. The filter device generally includes a filter layer, and the waste gas is screened and filtered through the filter layer. The filtering effect is poor, and the particles in the exhaust gas will block the filter layer, causing the filter device to not work properly
