Waste gas reducing suction filtration device

Abstract

The invention discloses a waste gas reducing suction filtration device which comprises a large-diameter curved surface tap, a telescopic sealing pipeline, a sealing clamping ring, a suction filtration barrel assembly, a suction pump, a valve and a gas collection bag. The large-diameter curved surface tap is installed on the lower portion of the telescopic sealing pipeline, and the outer side of the connecting area of the large-diameter curved surface tap and the telescopic sealing pipeline is sleeved with the sealing clamping ring; the upper portion of the telescopic sealing pipeline is connected with a bottom air inlet of a suction filtration barrel assembly, an air outlet in the upper portion of the suction filtration barrel assembly is provided with an air extracting pump, the outlet end of the air extracting pump is provided with a connecting pipe with an inner plug, the connecting pipe is provided with a valve, and the other end of the connecting pipe is connected with an air collecting bag. The waste gas reducing suction filtration device can filter and collect exhaust gas of exhaust ports of garbage incinerators with different calibers, solves the problem that a common exhaust gas sampling device cannot collect the exhaust gas of the exhaust ports with different calibers, is telescopic and adjustable in overall length, is convenient to carry, can accurately monitor the content of particulate matters in the exhaust gas, and can provide an actual sample for collecting particulate matters in the waste gas.

Description

technical field [0001] The invention relates to the field of waste gas variable-diameter suction filtration devices, in particular to a waste gas variable-diameter suction filtration device. Background technique [0002] In recent years, with the continuous improvement of people's awareness of environmental protection, some domestic waste generated in people's lives is usually incinerated and related supporting materials are added in accordance with relevant national regulations, and these domestic wastes are recycled and reused into different types. environmentally friendly building materials. In the process of incinerating garbage and waste, the garbage incinerator will produce a large amount of waste gas. In order to reduce or remove these waste gases, people need to sample the waste gas generated by the garbage incinerator, and then detect it through supporting testing equipment or instruments. The specific components in these exhaust gases can be removed or degraded by...

Problems solved by technology

At the same time, the present invention can filter and collect waste gas from exhaust ports of waste incinerators with different calibers, which solves the problem that ordinary waste gas sampling devices cannot meet the requirements of collecting waste gas from exhaust ports with different calibers. At the same time, it can more accurately monitor the content of particulate matter in the exhaust gas, and provide actual samples for collecting particulate matter in the exhaust gas. It is suitable for popularization and use when collecting exhaust gas samples at the exhaust ports of waste incinerators with different calibers.
