Description

Centrifugal type wet air cleaner {CENTRIFUGAL WET TYPE AIR CLEANER}

The present invention primarily collects fine particulate dust, harmful gas, odor particles, pathogens, and bacteria in the air by spraying washing water and generating swirling air in the intake air to collect them in a highly efficient wet manner, and secondly, the specific gravity of gas and liquid. By purifying air by centrifuging the washing water which collected the pollutants in the air using the difference (1: 1000), air or gas was formed by constructing a vortex chamber using a strong centrifugal force based on the rotational speed of the centrifugal impeller. It relates to a centrifugal type wet air cleaner.

Conventional air cleaners generally use dry filters in the form of solids, but they do not completely collect and purify microparticulate dust, and when air containing dust is attracted, they accumulate on the surface of the filter cloth, and the dust collection efficiency is drastically due to filter clogging. It may be degraded to become a breeding ground for pathogens or bacteria, and thus there is a problem of maintenance due to regular replacement. Due to the discarded dry filter nonwovens, secondary environmental pollutants are generated, which is a major cause of environmental pollution.

The present invention has been filed in "Wet purification system for automobile exhaust gas using a centrifugal impeller", Korean Utility Model Application No. 20-2002-0033201 (the same applicant and inventor), the structure and operating principle of purifying air more efficiently Patent application of “centrifugal type air purifier”, patent registration No. 20-0328651 (Technology Evaluation Confirmation Registration) and dual patent publication No. 10-2004-0043138 and “Air purifier using centrifugal impeller”, patent Invention for miniaturization and lightening structure to have a commercial property based on Publication No. 10-2004-0099193 (same applicant and inventor), after collecting the bacteria, dust, fine particles and other contaminants contained in the air using the washing water It is based on aerodynamics that generate centrifugal force using a centrifugal impeller and a spiral structure that are rotated by an electric motor. Therefore, based on the difference in specific gravity between gas and liquid (1: 1000), the air is centrifuged from the liquid contaminated water that collects the pollutants in the air in the collection chamber. To keep it.

 As a conventional technique, an air purifying apparatus including photocatalyst, electrostatic precipitating, and plasma has been developed to improve the problems of a dry filter type air purifier, but the purification efficiency is low or almost impossible for fine dust, tobacco smoke, and harmful gases having 5 μm or less. Do. Electrostatic precipitating method of purifying air by using static electricity based on high voltage electricity is known to have ozone side effects that are harmful to human health. As a conventional technique, a centrifugal type wet air purifier based on indirect swirl flow, which has a structure for generating swirl flow by a suction fan, is almost impossible to collect and purify fine dust, tobacco smoke, and harmful gases having a diameter of 5 μm or less. In addition, it is not suitable for industrial clean rooms that require a dust collection efficiency of 99.9% based on 0.3μm dust collection degree to clean the dust in the air by limited centrifugation. In the conventional wet air purifier, there is a water film contact method that draws air flow and purifies air by viscous adhesion of water by two-dimensional water film surface contact. Only contaminants in the air that come into contact with the water film surface area are purified by the viscous adhesion of water, and most fine dust and contaminants that do not come in contact with the water film surface area are not purified, resulting in low air purification efficiency of 70%. It is a problem that corrode precision equipment due to the discharge of air containing chlorine, which is not practically suitable for industrial clean room and hospital facilities requiring air purification efficiency of 99.9%. The pollutant-containing moisture also comes out with the exhaust air, so the actual air cleanness is very low, and the pollutant is also accompanied by moisture, which is known to be more harmful to human health or health.

The present invention is to improve the conventional problems as described above, and to purify contaminants including air bacteria and dust by centrifugation using the specific gravity difference with the gas, centrifugal separation type using an electric motor An air purifier, comprising a method of generating a centrifugal force using a centrifugal impeller in which bacteria, dust, fine particles and other contaminants contained in the air are rotated at high speed by an electric motor. It is configured to be clean.
