Problems solved by technology
[0003] Most of the existing gas filter devices only filter one or two or three kinds of pollutants. At the same time, most of the filter devices only filter the polluted gas once, and cannot completely filter out the pollutants in the air. To improve the filtration efficiency, the gas can only be filtered repeatedly, or connected to multiple identical devices for filtration. While the filtration effect is not good, the cost of use is also greatly increased

The invention relates to a multistage filtering device for gaseous pollutants. The multistage filtering device comprises a primary filter pipe, a secondary filter pipe, a tertiary filter pipe and a quaternary filter pipe, a liquid injection opening is formed in the middle of the top of the primary filtering pipe; a liquid outlet is formed in the middle of the bottom of the primary filter pipe; anair inlet is formed in one end of the primary filter pipe; a connecting opening is formed in the other end of the primary filtering pipe; a liquid level meter is fixedly mounted at the front end of the primary filter pipe; one side in the primary filter pipe is fixedly connected with a baffle plate; a baffle is fixedly connected to the middle of the interior of the primary filter pipe, a second baffle located on the left side of the connecting opening is fixedly connected to the other side of the interior of the primary filter pipe, an air inlet hole is formed in the top of the baffle, an airinlet pipe is fixedly installed in the air inlet hole, and a porous exhaust plate is fixedly installed at the bottom of the air inlet pipe. The problems that filtering equipment is incomplete in filtering, large in size and high in use cost are solved.
Description
technical field [0001] The invention relates to the technical field of multi-stage filtering devices, in particular to a multi-stage filtering device for gas pollutants. Background technique [0002] Air pollutants are caused by a mixture of gaseous, volatile, semi-volatile, and particulate matter (PM), with highly variable composition. The composition of air pollution is influenced by many factors, including meteorological conditions, time of day, number of days of week, industrial activity, and traffic density. Due to different sources, the chemical composition of particulate matter in the air varies significantly. For example, particles in the earth's crust (soil and sand) are mainly silica, while particulate matter from fossil fuel combustion in industrial activities and There are also interactions between atmospheres. [0003] Most of the existing gas filter devices only filter one or two or three kinds of pollutants. At the same time, most of the filter devices only...
