Purification device unit and purification device

Abstract

The invention provides a purification device unit and a purification device, and belongs to the field of purification equipment. The purification device unit comprises a casing assembly and a filtering assembly, wherein the casing assembly comprises a first casing and a second casing; a second smoke gas passage is formed between the first casing and the second casing; the second smoke gas passageis provided with an air inlet passage and an air outlet passage separated by a separation plate; an air outlet is formed in a casing wall, corresponding to the air outlet passage, of the first casing;the filtering assembly comprises a filtering screen disc, a transmission element and a flow guide impeller; the flow guide impeller can guide the airflow introduced into the filtering screen disc tothe radial direction of the filtering screen disc so that the airflow can be cut in the peripheral region near the filtering screen disc. The purification device unit solves the problem that the center region of the filtering screen disc can be easily blocked; partial smoke gas disengaged from the purification screen disc can enter the second smoke gas passage through a first smoke gas passage andis then filtered; the filtering efficiency is improved. The purification device comprises at least one purification device unit.

Description

technical field [0001] The invention relates to the field of purification equipment, in particular to a purification device unit and a purification device. Background technique [0002] At present, PM2.5 is mainly affected by two aspects, one is climate factors, and the other is pollutant emissions. Gas purification equipment plays a role in gas filtration, but there are many problems in the purifiers currently on the market, 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 ga...

AI Technical Summary

Problems solved by technology

[0005] The first object of the present invention is to provide a purification device unit, which can not only solve the problems that the network disk is easily blocked by oily smoke or other polluted exhaust gas, easily produces fire hazards, and the cleaning and maintenance cycle of the network disk is short, it can also make some The oily fume detached from the filter plate enters the second flue gas channel from the first flue gas channel for re-purification and filtration, which protects the core components of the secondary purification from oil fume damage, reduces the hidden danger of fire, and greatly reduces the second The resistance of the flue gas channel greatly reduces the energy consumption of smoke exhaust and greatly improves the purification and filtration efficiency
