Description

The present invention relates to a gas-liquid contact type air cleaner that purifies air by bringing it into contact with water.

  As an indoor air cleaning device, an air cleaner that removes dirt in the air by bringing air into contact with water is used. As this air cleaner, there are known a method in which cleaning water is sprayed in a cleaning room as a shower and then brought into contact with contaminated air to purify, or a method in which contaminated air and cleaning water are brought into contact with a plate having many through holes. ing.

There are many prior arts for air cleaning devices and the like. There are air purifiers that can sterilize air, air cleaners that can adjust humidity, and the like, but there are the following as prior means focusing on the structure and running cost. The exhaust gas is taken into the blast pipe using a blower and made into a horizontal flow, sent into the inside of the air purification device main body, efficiently in gas-liquid contact with the water film of the filler, and pollutants in the exhaust gas migrate, Further, the exhaust gas that has risen comes into direct gas-liquid contact with the sprayed liquid, and the remaining pollutants are transferred, purified, and discharged outward (Patent Document 1), sirocco for blowing air. The other end of the duct having a fan and having a ventilation opening at one end is introduced into a water storage tank in which cleaning water is stored, and the wall surface of the duct is immersed in the cleaning water. There is an air cleaner (Patent Document 2) provided with a large number of through holes communicating with the inside and outside of the duct.

In addition, water H ₂ O used as washing water has a strong electrostatic property as shown in Fig. 1 because oxygen atoms are polarized on the anode and hydrogen atoms are polarized on the cathode due to the large difference in electronegativity between oxygen and hydrogen. They are connected by attractive force. Therefore, the boiling point and melting point of water are abnormally high, and it has the ability to dissolve ionic compounds due to its polarization. In water molecules, the positive polarization (O ^{σ +} ) attracts anions and the negative polarization (H ^σ− ) attracts cations, because this force is large enough to break the ionic crystal into a solution.

In chemistry, a cluster is defined as “an assembly of two or more molecules or atoms with relatively weak interactions such as van der Waals forces and hydrogen bonds”. Liquid water is a typical substance forming a cluster, and water obtained by decomposing the cluster is expressed as cluster-decomposed water. There are various theories as to how much this water cluster can decompose and how long it takes to decompose. Currently, the most believed cluster of liquid water is a mixture of linear and branched n-mer clusters and polygonal clusters ranging from quadrangles to ellipsoids (of which the pentagon has the highest quantitative ratio). It is thought that the cluster does not exist stably for a long time in the cluster state of liquid water, but has a very dynamic structure that is born or broken on the order of 1 ps ( ^10-12 seconds). It is the theory that you are doing.
Furthermore, water is a diamagnetic material, and liquid water does not form a magnetic domain due to thermal disturbance, and the influence of the magnetic field is limited to individual water molecules. However, there is also the idea that by passing a magnetic field, a part of each water molecule is clustered and activated, and the effect is controversial.

There are the following applications as prior arts that utilize the above water properties and decompose water clusters to activate water and expect some effect.
A heating means for heating water from the water container, a coffee extraction chamber for extracting coffee liquid, a hot water supply means for supplying hot water obtained by the heating means to the coffee extraction chamber, and a storage container for storing the extracted coffee liquid From a water heater (Patent Document 3) that improves the extraction efficiency of coffee by subdividing a cluster of water by magnetic force and facilitating the penetration of water into the coffee powder. Rotate the intake air and the connecting screw by using the discharge speed, rotate the coaxial rotary blade by using the rotational force to contain fine bubbles in the water, and further stir the bubbles and bubbles. By repeating the enormous amount of bubbles and subdividing the bubbles by the fusion of, free chlorine is contained in the gas constituting the bubbles and diffused in the atmosphere together with them to achieve dechlorination and the like. A water purifier (Patent Document 4) that subdivides a water cluster, which is said to be enlarging by passing a magnetic field generated by a rotating magnet intermittently or passing through a combination of a plurality of magnetic fields. A wastewater treatment apparatus having wastewater treatment means for treating wastewater containing carbon, nitrogen, phosphorus, persistent organic substances, heavy metals, colloidal inorganic substances, etc. The wastewater treatment facility is designed to purify the wastewater by providing a magnetic treatment device that subdivides the wastewater flow that flows at a predetermined flow velocity by the magnetic force in the flow pipe of the wastewater treated and discharged by the wastewater treatment means. (Patent Document 5).

Japanese Patent Laid-Open No. 2004-202306 JP-A-9-173754 JP 2008-295624 Japanese Patent Laid-Open No. 11-5080 JP 2006-55826 A

In a gas-liquid contact type air cleaner, the surface of the cleaning chamber is filled with lasing, etc., and the surface of the liquid is increased to increase the surface area of the liquid. Increasing ingenuity has been made. However, in order to improve the gas-liquid contact efficiency when the gas passes through the cleaning chamber, there is a problem that if the packing is made finer, the ventilation resistance increases on the gas side by that amount. It is necessary to increase the cross-sectional area of the chamber, resulting in a large apparatus and high initial cost.

The inventor, who has developed cleaning and purification equipment for air and water for many years, has a simple structure and a running cost for a gas-liquid contact type air cleaner that cleans factory and indoor air. We have been studying air cleaners that can reduce the above. Furthermore, using the above-mentioned properties of water, it was thought that it was possible to clean the air by making cluster-decomposed water in a very short time by a magnetic field. Therefore, the present inventor has invented a gas-liquid contact type air cleaning device that takes in a blowing function capable of efficiently contacting water and air into the air cleaning device and at the same time uses cluster-decomposed water as cleaning water.

The problem to be solved by the present invention is an air cleaner that removes dirt in the air by bringing the air and water into contact with each other. The structure is simple, the running cost is low, and the contaminated air is efficiently purified. It is to provide an air cleaner that can.

Contaminated air and cleaning water flow into the outer cylinder from the contaminated air inflow hole and the cleaning water inflow hole in the upper part of the outer cylinder, and flow down in the direction of the rotating disk from the central opening of the upper partition plate. As the rotating shaft rotates, the rotating disk and rotor blades also rotate. By this rotation, the washing water becomes mist and flows to the inner wall surface of the outer cylinder while being in contact with the contaminated air. On the inner wall surface of the outer cylinder, there is no opening in the upper partition plate, and there is an opening in the lower partition plate. Therefore, the mist-like washing water and air flow downward along the inner wall of the outer cylinder. As described above, the air cleaner is characterized in that air and cleaning water are brought into contact with each other by rotating the rotating shaft and further has a blowing function.

Between the upper and lower parts of the outer cylinder, an upper partition plate and a lower partition plate are set up vertically from the inner surface of the outer cylinder, that is, the upper partition plate and the lower partition plate are provided so as to be horizontal with the upper surface or the bottom surface of the outer cylinder.

The contaminated air and the cleaning water come into contact with the contaminated air in the form of mist by the rotation of the rotating disk on which the upper partition plate and the rotor blades are mounted and the lower partition plate, thereby cleaning the air. By using a plurality of combinations of the upper partition plate, the rotating disk on which the rotor blades are mounted, and the lower partition plate, the cleaning effect of contaminated air is improved.

Subsequently, the third invention is the air cleaner according to any one of the first invention and the second invention, in which a plurality of through holes are provided in the rotor blade.

Subsequently, the fourth invention is the air cleaner according to any one of the first invention and the second invention, wherein the rotating blade is a wire mesh with an edge.

In the third invention, the rotor blade is provided with a large number of through holes, but in the fourth invention, it is a wire mesh with an edge. The reason for the edging is that the strength of the rotating blades is not sufficient with the metal mesh alone, and the edging is performed considering the strength of the rotating blades.
