Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a gas purifier that can maintain an excellent purification effect permanently, is easy to manufacture, and is excellent in maintenance and handling.

[Prior art]

Generally, when a contaminated gas such as indoor air or various gases in a factory is used as a clear gas, a gas purifier is usually used.

In a conventional gas purifier, generally, in a gas flow passage in a container, a packaging purifying agent in which carrier particles carrying a purifying agent such as a deodorant substance is wrapped in a non-woven fabric is brought into contact with a gas to prevent contamination of the gas. Purification is performed by reacting or absorbing the causative substance with a purifying agent.

[Problems to be Solved by the Invention] However, the gas purifier having such a structure has the following problems. That is, since the gas is purified only within the range of the purifying ability of the purifying agent carried in the carrier particles to be used, the purifying effect decreases with time when used for a long time.

In addition, in manufacturing, a step of supporting the purifying agent on the carrier particles and a step of wrapping with a non-woven fabric or the like to form a packaging purifying agent are required, which is complicated and the production efficiency is low.

[Means for Solving the Problems]

As a result of intensive studies in view of the above problems, the present inventors have found that the problem can be solved by using a sheet-like material in which a cleaning liquid is permeated by capillary action in a specific mode, and have proposed the present invention. .

That is, according to the present invention, in a container having a gas inlet and an outlet and provided with a purifying liquid bath in which the purifying liquid is stored at the bottom, a plurality of gas circulation holes are provided, and the purifying liquid permeates by capillary action. Two or more possible sheet-like materials are sequentially moved in the gas flow direction, and when viewed facing each other in the gas flow direction, the positions of the gas flow holes adjacent to each other in the front-back direction are not overlapped. The gas purifier is characterized in that it is hung vertically from the inner surface of the container, and the lower end of the sheet-like material is immersed in the gas purification liquid.

The purifying liquid used in the present invention can be used without any limitation as long as it is a liquid having a function of purifying polluted gas. Generally, among known purification agents such as deodorants, deodorants, fragrances, rust preventives, antifungal agents, etc., which consist of deodorant components extracted from natural substances, one of which is a liquid or water-soluble compound Alternatively, it is a liquid or aqueous solution in which a plurality of types are used in combination. Among these, as the deodorant, a deodorant component extracted from a plant such as green tea is particularly suitable.

The sheet-like material used in the present invention needs to have a property capable of penetrating the cleaning liquid by a capillary action. As such a sheet, a cloth such as a non-woven fabric or a woven fabric, paper, or the like can be used. Of these, non-woven fabric is particularly preferable because of its strong ability to permeate the cleaning liquid by the capillary action. In the case of paper,
It is preferable to use one having a certain degree of water resistance in terms of shape retention. It is desirable that the thickness of the sheet-like material is appropriately selected in consideration of the carrying capacity, strength, etc. of the cleaning liquid for the sheet-like material. Usually, it is selected from the range of 0.01 to 10 mm.

The gas flow holes formed in the sheet-like material are sheet-like materials that are adjacent to each other in the front-back direction when viewed facing each other in the gas-flowing direction, as long as the positions of the gas flow holes do not overlap. May be provided. As for the shape of the gas flow holes, it is generally desirable to form the gas flow holes in the form of slits or small circles, ellipses or polygons. The number of gas flow holes provided in one sheet-like material, the area ratio of the gas flow holes in the sheet-like material, and the number of used sheet-like materials are the gas purification efficiency and gas flow due to contact with the sheet-like material. It may be appropriately selected in consideration of the goodness of the above. Generally, the larger the number of sheets used, the higher the gas purification efficiency, but on the other hand, the problem of good gas flow occurs. Therefore, it is generally preferable to select from 3 to 10.

The container used in the present invention is not particularly limited in material and the like as long as it has the above-described gas inlet and outlet and has a cleaning liquid bath at the bottom. Further, the container has a replenishing port for the cleaning liquid reduced by use or a mounting port for a vertically extending sheet-like object, and a lid or the like for covering the upper surface of the cleaning liquid bath may be additionally provided if necessary. it can.

[Action]

According to the gas purifier of the present invention, the purifying liquid permeates and rises by the capillary action from the lower end portion immersed in the purifying liquid and is carried by the sheet-shaped material hanging from the inner surface of the container. Therefore, when the dirty gas comes into contact with the portion other than the gas flow holes of the sheet-like material, the substance causing the pollution such as the malodor in the gas reacts with or is absorbed by the purifying agent to purify the gas.
On the other hand, in the gas purifier of the present invention, two or more sheet-like materials are sequentially adjacent to each other in the gas flow direction, and when viewed facing each other in the gas flow direction, the gas of the sheet-like objects is adjacent to each other. It is provided so that the positions of the flow holes do not overlap, and the contact efficiency between the portion other than the gas flow holes of the sheet-like material and the flowing gas is extremely good. Therefore, the gas taken into the container is generally purified and taken out in the process of passing through the bypassed gas flow passage formed by vertically arranging the sheet-like material.
