The present invention relates to a device for purifying air contaminated with bacteria, etc., and more specifically,
Related to an air purifier using a so-called electrostatic method, which charges airborne particulate pollutants, including bacteria, in air contaminated with bacteria, etc., by means of corona discharge, etc., and collects them on a dust collection electrode. It is something. BACKGROUND ART In recent years, as air pollution has progressed, there has been a need in various fields to purify the air supplied indoors, and particularly in the field of medicine, medical care and medical research are being conducted in sterile rooms. Various air purification methods have been proposed for this purpose, one of which is to charge floating particulate pollutants using corona discharge, etc., and collect them on a dust collecting electrode. There is a so-called electrostatic precipitator,
Conventional electrostatic precipitators have the disadvantage that they are complicated because they use ultraviolet lamps to sterilize the collected dust. One method of sterilizing floating dust in the air was to collect and sterilize the dust with a mechanical filter impregnated with a sterilizing agent, but this method had the disadvantage of high pressure loss and the need for a large-capacity blower. It was hot. In addition, such conventional sterilizer-impregnated filters have low electrical conductivity and cannot be used as dust collection electrodes in electrostatic precipitators. Furthermore, since conventional dust collecting electrodes are metallic and lack porous properties, they cannot be sufficiently impregnated with water-soluble sterilizers, so if the amount of collected dust increases, there is a risk that sufficient sterilization may not be achieved. There was a risk that the metal in the dust collection electrode would be eluted into the aqueous solution. An object of the present invention is to eliminate such conventional drawbacks and provide an electrostatic precipitator air cleaner that maintains sufficient bactericidal properties over a long period of time. Next, the configuration of the present invention will be explained. 1 and 2 are a sectional view and a perspective view thereof of an embodiment of the present invention, and FIG. 3 is a perspective view of a removable dust collecting electrode member used in the embodiment. In these figures, 4 is a discharge electrode that discharges at the protruding end 12, and 8 is a dust collection electrode member formed by collecting a plurality of cylindrical dust collection electrodes 1, which can be attached to and detached from the discharge electrode member 5 in which the discharge electrode 4 is implanted. They are freely connected, and discharge is made from the protruding end 12 toward the inner wall of the dust collecting electrode 1. The dust collecting electrode member 8 is formed of a non-metallic porous conductive material, and is impregnated with an aqueous solution of a disinfectant containing a water retention agent and an electrolyte. In order to form the dust collecting electrode member 8, for example, a non-metallic powder conductive material such as conductive carbon is mixed with a non-metallic material such as molding plastic, and this is mixed by a known method. Molded into a porous body with open cells. Further, the dust collecting electrode member 8 can also be created by making an inorganic porous material such as gypsum contain an electrolyte. The impregnating liquid with which the dust collection electrode member 8 is impregnated is prepared by mixing a water retaining agent such as ethylene glycol or glycerin and an electrolyte solution such as a metal salt with an aqueous solution or aqueous emulsion of a bactericide or disinfectant as described below. Disinfectant Phenylmercury acetate Bisdicene Pentachlorophenol PCP Hexachlorophene 2-(4-thiazolyl)benzimidazole Polyhexamethylene Viganazine Hydrochloride Orthophenylphenol Disinfectant Carbolic acid Reverse soap Borate Cresol Generally, microorganisms and bacteria are removed from dust. They adhere and are transported indoors, and the type of them does not necessarily vary depending on the season, region, and environment. Therefore, it is preferable that the sterilizer or disinfectant used in the present invention be effective against a wide range of microorganisms and bacteria, but depending on the use and purpose of the air purifier, several types of sterilizers that are not contraindicated may be used. Agents and disinfectants may also be used together. Note that the present invention is not limited to the type of electrostatic precipitator, and may use a linear discharge electrode as shown in FIG. Next, the effects of the present invention will be explained. Since the air purifier of the present invention uses an electrostatic precipitator, there is little pressure loss, and the device is simple because it does not use a sterilizing lamp unlike conventional methods. When the air purifier of the present invention is used, when the electrostatic precipitator is activated, the dust in the dust-containing air is charged by corona discharge, and then collected on the surface of the dust collection electrode, and the bacteria in the dust are collected. The air is sterilized by the disinfectant impregnated in the electrode and purified air is discharged. In the present invention, when impregnating the dust collection electrode with the sterilizer, the aqueous solution containing an electrolyte is used, so the electric resistance is low and a sufficient dust collection effect is exhibited, and the dust collection electrode is made of a non-metallic conductive member. Therefore, there is no need to worry about the dust collection electrode being eluted even when a discharge current is applied. Since the disinfectant of the present invention is an aqueous solution containing a water retention agent, it is impregnated into the porous dust collecting electrode as a solution for a long time. It is generally known that the surface tension of a liquid decreases when a voltage is applied to it (for example, Japanese Patent Publication No. 108905/1983). As the surface tension is lowered by the application of voltage, the collected dust is successively wetted and incorporated into the disinfectant aqueous solution, and continues to ooze out to the surface, and as the dust accumulates, it flows from the inside of the pores to the surface. Disinfectant supply is carried out. Therefore, according to the present invention, the bactericidal effect can be maintained for a long time. Examples Example 1 The air purifier shown in FIGS. 1 and 2 is equipped with the dust collection electrode member shown in FIG. A filter was installed to prepare sample A. In sample A, the dust collecting electrode member contained inverse soap (alkylbenzyl dimethyl ammonium chloride...5 parts 2-(4-thiazolyl)benzimidazole...1 part polyoxyethylene lauryl) ether
Sample B was impregnated with a sterilizing disinfectant solution consisting of 2 parts glycerin, 10 parts water, and 100 parts.
A high voltage is applied between the discharge electrode 4 and the dust collection electrode 1 of Sample A and Sample B by a high voltage power supply (not shown) to cause corona discharge, while each channel 2 is
After supplying outdoor air for a certain period of time (3 hours each for 3 days), the number of bacteria adhering to the filter paper of each sample was examined by a known agar culture method, and the following results were obtained. For comparison, Sample C was Sample A in which only outdoor air was introduced without corona discharge.
