Purification separation device for fogdrop and granule in gas

Abstract

The invention provides a purification separation device for fogdrop and granules in gases. The purification separation device comprises a front-end separator, wherein the front-end separator comprises an outer-layer shell (6) and an inner-layer shell (9); an annular cavity is formed between the outer-layer shell (6) and the inner-layer shell (9); one end of the inner-layer shell (9) is a gas inlet end (1); the other end of the inner-layer shell (9) is a gas outlet end (12); a centrifuging part (2) for converting fed straight airflow into rotational airflow is arranged at the gas inlet end (1) of the inner-layer shell (9); between the centrifuging part (2) and the gas outlet end of the inner-layer shell (9), a plurality of exhaust holes (3) which are communicated with the annular cavity and interior of the inner-layer shell (9) are formed in the side wall of the inner-layer shell (9). By adopting the purification separation device for fogdrop and granules in gases, captured fogdrop and granules can be conveniently and rapidly discharged out, and thus a relatively remarkable separation effect is achieved.

Description

technical field [0001] The invention relates to the field of flue gas, natural gas and shale gas purification equipment, in particular to a purification and separation device for mist droplets and particles in gas. Background technique [0002] With the intensification of environmental pollution in our country, the smog weather has become more and more serious, which has brought increasingly serious impacts on people's lives and bodies. The state has introduced strict policies to limit pollutant emissions, especially for coal-fired power plants with ultra-low emission restrictions, and the dust content is not higher than 10mg / Nm3, or even 5mg / Nm3. There are many kinds of existing technologies. In the existing rotary separation device, gas and solid powder enter from the left, and then generate centrifugal force through the blades, in which the mist and particles are thrown to the side wall and discharged into the collection tank, among which is the steady vortex Rod, so it ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of low purification efficiency of existing flue gas purification equipment, the present invention provides a purification and separation device for mist droplets and particles in gas, which can conveniently and quickly remove the captured mist Drips and particles are discharged, so the separation effect is more obvious
