Abstract

The invention provides a purification and separation device for mist and particles in gas, comprising a front-end separator, the front-end separator contains an outer shell (6) and an inner shell (9), the outer shell (6) An annular cavity is formed between the inner shell (9), one end of the inner shell (9) is the gas inlet port (1), and the other end of the inner shell (9) is the gas outlet port (12), The gas inlet end (1) of the inner shell (9) is provided with a centrifugal component (2) capable of converting the incoming linear airflow into a swirling airflow, and the gas flow between the centrifugal component (2) and the inner shell (9) Between the outlet ports (12), the side wall of the inner shell (9) is provided with a plurality of outlets (3) communicating the annular cavity with the inside of the inner shell (9). The purification and separation device for mist and particles in the gas can conveniently and quickly discharge the captured mist and particles, so the separation effect is more obvious.

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 ...
