Waste gas suction and purification device and using method thereof

Abstract

The invention discloses a waste gas suction and purification device and a using method thereof. The device comprises an exhaust pipeline and a filter mechanism connected to the exhaust pipeline. The filter mechanism comprises a plurality of filter pipes and gas ejector pipes in one-to-one correspondence with the filter pipes; the filter pipes are movably connected with the corresponding air injection pipes; the filter pipes are parallel to the axial direction of the exhaust pipeline; each filter pipe is an axially-through hollow pipe body, a filter screen is arranged in each filter pipe, and acollecting device is arranged near each filter screen. A flexible material section is arranged on each filter pipe and divides each filter pipe into a first filter pipe and a second filter pipe. Eachfirst filter pipe is connected to the side, close to an upper opening of the exhaust pipeline, of the corresponding flexible material section; each second filter pipe is connected to the side, away from the upper opening of the exhaust pipeline, of the corresponding flexible material section. A rotating mechanism is arranged in each filter pipe. By changing the suction position in the exhaust pipeline, the exhaust gas suction efficiency can be adjusted in time, and filtered residual exhaust gas can be blown away from the control area.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a waste gas suction and purification device and a use method thereof. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially chemical plants, steel plants, pharmaceutical plants, coking plants, oil refineries, etc., and the production of domestic waste gas from human life, the exhaust gas has a strong smell, which seriously pollutes the environment and affects human health. Industrial waste gas emitted by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without treatment and reaches the standard, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. Toxic and harmful substances in indu...

Problems solved by technology

[0004] However, even if the exhaust gas is specified at the source, the exhaust gas will always have a certain impact on the environment, and the existing exhaust gas purification device does not have the function of recovering the waste gas filtration residue and then processing it into valuable products. Solve the problem of exhaust gas emission from the perspective of economic interests, and most of the exhaust gas emission devices are built at the downwind outlet, which cannot actively control the direction of emission, and is subject to geographical restrictions
