Air purifying device

Abstract

The invention discloses an air purifying device and relates to the field of air purification. The air purifying device comprises an air inducing device, dust removing systems and a sewage treating system, wherein the air inducing device consists of an air inlet pipe, a volute-shaped air channel, a seat ring and guide vanes; each dust removing system consists of a glass reinforced plastic shell, an exciting coil, a ceramic drum, a pressing cover, an air purifying outlet, a dehydrator, a spraying nozzle, an annular electrode, a connector and a sewage discharging pipe; the sewage treating system consists of a sewage collecting box, an ultrasonic probe, a filtering membrane, a water discharging pipe, a TiO2 nano coating, an electromagnetic valve and a liquid discharging pipe; dusty air is guided into an inner cavity of each ceramic drum along the circumferential direction, and dust is charged with positive electricity by the annular electrodes and rises spirally in a magnetic field so as to increase the probability of collision of the dust and liquid drops. The TiO2 nano coating is arranged on the inner surface of the bottom part of the sewage collecting box, ultraviolet lamps are densely distributed on the surface of a hemisphere and three ultrasonic probes are uniformly distributed on the surface of the hemisphere; sewage is filtered and recycled after being sterilized due to synergy of ultrasonic waves and ultraviolet and combination with photo-catalytic oxidation reaction. The air purifying device disclosed by the invention has the advantages that dust removal, deodorization and sterilization of polluted air are synchronously realized, the water consumption is less and no secondary pollution is caused.

Description

technical field [0001] The invention relates to the field of air purification, and in particular refers to an integrated air purification device that utilizes magnetic force to control dust movement to improve the efficiency of liquid droplets to capture dust, and utilizes ultrasonic waves to cooperate with ultraviolet rays and photocatalytic oxidation reactions to disinfect and sterilize sewage. Background technique [0002] At present, there are many dedusting devices with different principles, but most of them have a single function and do not have the ability to sterilize and deodorize. US6488269 "Wet scrubber" (wet dust collector) has large water consumption, low purification effect in some areas, and some dust particles escape. There is no supporting treatment device for a large amount of sewage formed during the dust removal process, causing secondary pollution of water bodies. Such as US2010307342 "ELECTROSTATIC DUST CATCHER" (electrostatic precipitator), JP201001240...

[0002] At present, there are many dust removal devices with different principles, but most of them have a single function and do not have the ability to sterilize and deodorize

US6488269 "Wet scrubber" (wet dust collector) has large water consumption, low purification effect in some areas, and some dust particles escape. There is no supporting treatment device for a large amount of sewage formed during the dust removal process, causing secondary pollution of water bodies

Such as US2010307342 "ELECTROSTATIC DUST CATCHER" (electrostatic precipitator), JP2010012400 "ELECTRIC DUST CATCHER" (electrical precipitator) utilizes the principle of electrostatic adsorption to remove dust, and the dust collector needs to be regularly vibrated to remove dust, which is easy to form secondary dust, CN200620084507.0 " The wire electrode is used in the wet electromagnetic desulfurization dust collector to pre-charge the dust. Under the joint action of electrostatic force and magnetic force, the dust particles contact with the water film on the inner wall of the anode tube to realize dust collection, which solves the problem of secondary dust. However, the wire electrode It is prone to electrical breakdown, requiring a certain electrode distance, specified field strength and specific operating conditions

CN200910132779.1 "A method of magnetic dust removal" uses magnetic force to remove magnetic dust such as iron, but the removal effect on non-magnetic dust is not good
