Purifying device shell and flue gas purifying device

Abstract

The invention provides a purifying device shell and a flue gas purifying device and belongs to the field of purifying equipment. The purifying device shell comprises a first shell and a second shell,wherein the first shell is set to be circular, and a cavity in the middle of the first shell is taken as a first flue gas channel; a second flue gas channel is formed between the first shell and the second shell and is provided with an air inlet channel and an air outlet channel separated by a partition plate; an air outlet is formed in a shell wall, corresponding to the air outlet channel, of thefirst shell, so that the radial direction of the first flue gas channel is communicated with the air outlet channel. The purifying device shell adopts the structure form; after colliding with the inner wall of the first shell, oily fume divorced from a purifying element is discharged into the second flue gas channel from the air outlet for re-filtering, so that the filtering efficiency of the purifying device shell cannot be affected, and the generation of secondary pollution of flue gas is reduced; therefore, energy conservation and environmental protection are realized; the flue gas purifying device comprises at least one purifying device shell.

Description

technical field [0001] The invention relates to the field of purification equipment, in particular to a housing of a purification device and a flue gas purification device. Background technique [0002] With decades of extensive and rapid economic development in China, the atmospheric environment has been greatly damaged, and severe smog has broken out in many places across the country. At present, PM2.5 is mainly affected by two aspects, one is climate factors, and the other is pollution. emissions. Gas purification equipment plays a role in gas filtration, but there are many problems in the purifiers currently on the market, such as high power consumption and low purification efficiency, resulting in high cost of air pollution control, general effect and difficult to maintain stability. [0003] For example, high-voltage static electricity, wet type, mechanical filter type and activated carbon type have a large amount of maintenance, complex structure, high operating cost...

Gas purification equipment plays a role in gas filtration, but there are many problems in the purifiers currently on the market, such as high power consumption and low purification efficiency, resulting in high cost of air pollution control, general effect and difficult to maintain stability

[0003] For example, high-voltage static electricity, wet type, mechanical filter type and activated carbon type have a large amount of maintenance, complex structure, high operating cost, unstable purification efficiency and short service life, and a dynamic centrifugal purifier on the market, one of which is a radial wire wound Through the high-speed rotation of the mesh disk, the radial wires continuously cut and hit the oil fume or other exhaust gas, so that the particles trapped on the mesh disk fly to the outer shell under the action of centrifugal force, and the oil fume hits the baffle at high speed To achieve the purpose of getting rid of oily fumes, but the outer shell structure of the network disk is very simple, usually a simple circular ring-shaped shell. resistance, which affects the deoiling efficiency, and is prone to secondary pollution, which is not energy-saving and environmentally friendly
