Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is more stable than before by using a frame equipped with a gas cleaning device, more specifically, by positively and efficiently utilizing the electric wind and the electrostatic suction force, which are electrochemical phenomena. The present invention relates to a frame equipped with a gas cleaning device that can not only improve the dust collection efficiency by the above operation, but also can improve the deodorization efficiency extremely quietly and extremely.

[0002]

[Prior art]

 Conventionally, as this type of gas cleaning apparatus, for example, there is one disclosed in Japanese Patent Laid-Open No. 63-59963.

That is, as shown in FIG. 5, the gas purifier disclosed in the above publication has a pair of positive and negative ionization electrodes 16 and a ground 17, and the negative electrode 16 a of the ionization electrode 16 is a platinum-impregnated honeycomb-like structure. In addition to using ceramics, a comb-shaped electrode is used for the positive electrode 16b.

In the gas cleaning apparatus 18 having the above structure, when a direct high voltage 19 is applied to the pair of positive and negative ionization electrodes 16, a corona discharge is generated between the pair of positive and negative ionization electrodes 16, and the ionization electrodes 16 are The gas in the vicinity will be ionized.

Further, the gas ionized as described above moves (arrow B) as an ion flow toward the negative electrode 16a, and gas convection is induced via the ion flow, and the negative electrode 16a The gas flow passes through the inside of the negative electrode, and fine particles such as fine dust and odor contained in the gas flow are charged by the electric field of the positive electrode 16b to the positive electrode, and the negative electrode is charged. It will be adsorbed to the negative electrode 16a by the negative electric force of 16a.

Therefore, the gas containing fine particles such as fine dust and odor is filtered and discharged (arrow C) while passing through the negative electrode 16a by the above series of repetitions, thereby being cleaned. It will be.

[0007]

[Problems to be solved by the device]

 However, the gas purifier having the above structure has the following problems.

That is, the ionization electrode 16 of the gas cleaning apparatus having the above-mentioned configuration applies a negative voltage to a so-called dust collecting electrode for adsorbing fine dust, odor and other fine particles in the gas, In addition, a positive voltage is applied to the electrodes for corona discharge for generating electric wind.

Therefore, a large amount of secondary electrons are emitted due to collision of ion particles, electrons, and the like with a positive electrode for discharge having a high current density, and a so-called avalanche phenomenon is likely to occur.

Therefore, not only the corona discharge generated between the pair of positive and negative ionization electrodes 16 becomes unstable, but also spark discharge easily occurs, and the electric field strength of each electrode unit for improving the dust collection efficiency is increased. Not only is it difficult to increase the strength of the dust collection, but some of the fine particles that have been affected by electron flow etc. are difficult to be adsorbed because the dust collection electrode is applied to a negative voltage. The dust collection efficiency of will also decrease.

Therefore, in order to improve the dust collection efficiency of the fine particles in the gas, it is necessary to reduce the size of the through hole 20 such as the honeycomb portion through which the gas flow of the dust collecting electrode passes. However, due to various electrical and structural restrictions, it was difficult to maintain a highly stable and highly efficient dust collection operation.

Further, in the gas cleaning apparatus having the above-mentioned configuration, a large amount of secondary electrons are emitted due to collision of ion particles, electrons, etc., with a positive electrode for discharge having high current density, which is a so-called electron avalanche phenomenon. And the corona discharge generated between the pair of positive and negative ionization electrodes 16 becomes unstable, and spark discharge easily occurs.

Therefore, the noise of the spark discharge generated through the corona discharge generated between the pair of positive and negative ionization electrodes 11 becomes unpleasant, and even if the gas purifier is downsized, its place of use must be considered. However, there was a problem that could be called a fatal injury even in actual use.

However, the present invention solves all the above problems, and it is highly stable and does not cause electron avalanche phenomenon at all, and the structure of the electrode for collecting dust is not restricted by a particular restriction. Not only is it possible to maintain highly efficient dust collection of particles and to maintain the quietness during gas cleaning, but it is also an object to provide a frame equipped with an extremely excellent gas cleaning device that can be used anywhere. .

[0015]

[Means for Solving the Problems]

 That is, the present invention resides in that the air cleaner 1 is provided in the forehead main body 10a in the forehead capable of storing photographs, pictures and the like.

Further, the gas cleaning apparatus 1 has a needle-shaped electrode 2 and at least one through hole 6 facing the needle-shaped electrode 2 and extending along the tip direction of the needle-shaped electrode 2. A positive electrode portion 4 provided with a dust collecting electrode 3, the needle electrode 2 being negatively applied, and the dust collecting electrode body 3a being positively applied; And the dust collecting electrode main body 3a is detachably attached to the gas cleaning device 1.

[0017]

[Action]

Further, the needle electrode 2 of the gas cleaning device 1 is negatively applied, and the dust collecting electrode body 3 a is integrally provided on the positive electrode part 4 and the positive electrode part 4 to which the positive electrode part 4 is positively applied. Between the needle electrode 2 and the dust collecting electrode body 3a, since the dust collecting electrode body 3a is detachably attached to the gas cleaning device 1. By making the electron flow and the ion flow generated in the same direction and making the electron-emitting side, which is the negative electrode, the needle-shaped electrode 2, the current density at the tip can be sufficiently increased, thus creating a stable and wide electric field region. Not only is it possible to collect dust, such as fine particles such as dust and odor, through the dust collecting electrode main body 3a without using a special dust collecting filter due to the stable and strong electric field range. And the dust collecting electrode body 3a is collected. Even if it is contaminated with dust, it is possible to instantly remove the dust collecting electrode body 3a from the gas cleaning device 1 to remove the dust collecting device, and attach it again to the gas cleaning device 1 for repeated use. .

Further, by enlarging the area of the positive electrode portion 4 facing the needle-shaped electrode 2 of the dust collecting electrode body 3a, the receiving area of the electron flow is widened and the electron rush density is lowered. A stable corona discharge will be maintained without causing an electron avalanche phenomenon.

Furthermore, since the dust collecting electrode body 3a that performs suction of electric wind and adsorption of fine particles such as dust and odor is positively applied, dust and odor that are influenced by electron flow The fine particles are more strongly adsorbed by the dust collecting electrode body 3a, and particularly the odor fine particles are a mixture of zeolite and pulp used in the dust collecting section 5, or activated carbon or dust containing the activated carbon. It can deodorize more strongly through the body's chemistry.

First, as shown in FIG. 1, in the gas cleaning device 1 provided on the forehead 10, the needle electrode 2 is applied negatively and the dust collecting electrode body 3a is applied positively. Since the electrode portion 4 and the dust collecting portion 5 formed by mixing zeolite and pulp having the positive electrode portion 4 are integrally formed, the needle electrode 2 and the dust collecting electrode body are integrally formed. By making the electron flow and the ion flow generated between 3a and 3a in the same direction and by using the needle-shaped electrode 2 on the electron emission side which is the negative electrode, the current density at the tip can be sufficiently increased and thus stable.

Dust can be collected via the main body 3a, Even when the dust collecting electrode body 3a is contaminated with dust, the dust collecting electrode body 3a is instantly removed from the gas purifying apparatus body 1a to remove the dust collecting material, and the gas purifying apparatus 1 is again provided with the dust collecting electrode body 3a. Not only can it be attached and used repeatedly, but it can also be disposable.

Further, by enlarging the area of the positive electrode portion 4 facing the needle-shaped electrode 2 of the dust collecting electrode body 3a, the acceptance area of the electron flow is increased and the electron rush density is lowered. A stable corona discharge will be maintained without causing an electron avalanche phenomenon.

Further, since the electrode body 3a for collecting dust, which attracts electric wind and adsorbs fine particles such as dust and odor, is positively applied, dust and odor, etc., which are affected by the electron flow The fine particles are more strongly adsorbed to the dust collecting electrode body 3a, and particularly the fine particles having an odor can be more strongly deodorized through the chemical nature of zeolite.

In the above embodiment, the needle-shaped electrode is erected on the negative electrode surface body to which a high voltage is negatively applied, and the negative electrode surface body is made of zeolite mainly containing silicic acid and aluminum oxide. At least one surface side of the formed dust collecting surface body is integrally provided, and the negative electrode surface body and the dust collecting surface body in the vicinity of the needle electrode are introduced with gas that penetrates each other. By forming a dust collection negative electrode by forming a through hole for water, it is possible to capture not only fine dust in the gas but also fine odor particles through the dust collecting surface made of zeolite. However, the material is not necessarily limited to zeolite, and may be formed of activated carbon or a dust collector containing the activated carbon, and may be a rubber-like or foam-like elastic body containing activated carbon. Carbon is contained in the elastic body However, the specific material, shape, thickness, location, quantity, etc. of the negatively applied needle electrode are not limited.

Further, in the above-mentioned embodiment, the dust collecting electrode is positioned at a predetermined distance from the needle electrode in advance so as to have the best electrolysis range with the needle electrode, and the dust collecting electrode is also arranged. The dust collecting electrode body of the dust electrode is integrally formed by the positive electrode portion positively applied and the dust collecting portion having the positive electrode portion, and the positive electrode portion and the dust collecting portion are respectively formed. They are alternately and integrally joined to each other so that they can be inserted into and removed from the gas cleaning device. It is essential that they have the best electrolysis range with the needle electrode, and that the dust collecting part is not always required. It does not need to be formed by mixing zeolite and pulp, and may be formed by only one of zeolite or pulp, or may be formed by activated carbon or a dust containing the activated carbon. Rubber-like or foam-like dust containing activated carbon Needless to say, it may be an elastic body, and the presence or absence of carbon is by no means limited.

Further, the gas cleaning device is integrally provided on the frame main body of the frame which is formed so as to have a substantially rectangular frame through a molding material such as synthetic resin, and the lower part and the upper part of the frame are provided. The gas introduction hole and the gas discharge port are formed, and the dust collection electrode insertion hole is further formed on the side. However, this structure is not always necessary. The shape and quantity of the electrode insertion hole forming part, etc., the forming part, etc. are not limited by any means, and the gas cleaning device need not be integrally provided on the forehead body, as shown in FIG. 4 (a).

[Effect of device]

 As described above, since the present invention is equipped with a gas cleaning device on the forehead body of the forehead, it can be used at any place without limitation.

Further, a positive electrode portion to which the needle electrode of the gas cleaning device is negatively applied and the dust collecting electrode body is positively applied, and a dust collecting portion integrally provided on the positive electrode portion. Since the dust collecting electrode body is detachably attached to the gas cleaning device, the electron flow and the ion flow generated between the needle electrode and the dust collecting electrode body are in the same direction. However, by using a needle-shaped electrode on the electron emission side, which is the negative electrode, the current density at the tip can be sufficiently increased, so that not only a stable strong and wide electric field region can be created but also the stable strong Due to the wide electric field range, it is possible to collect dust such as fine particles such as dust and odor without using a special dust collecting filter, etc. through the dust collecting electrode body, and the dust collecting electrode. Even if the main body becomes dirty with dust, it will The electrode body can be detached from the gas cleaning device to remove dusts, and then attached again to the gas cleaning device for repeated use.

Further, by increasing the area of the positive electrode portion facing the needle-shaped electrode of the above-mentioned dust collecting electrode body, the area for accepting the electron flow is widened and the electron plunge density is lowered, whereby the electron avalanche phenomenon is generated. A stable corona discharge will be maintained without causing electric shock.

Further, since the main body of the dust collecting electrode, which performs the suction of electric wind and the adsorption of fine particles such as dust and odor, is positively applied, the amount of dust and odor affected by the electron flow is small. The particles are more strongly adsorbed to the dust collecting electrode body, and especially the odorous fine particles are the chemical properties of the mixture of zeolite and pulp used in the dust collecting part or the activated carbon or the dust collector containing the activated carbon. It is possible to deodorize more strongly via.

Therefore, the electron avalanche phenomenon does not occur at all, and the structure of the dust collecting electrode is not subject to any particular restriction. The dust collecting operation of the particles is highly stable and highly efficient, and the silence during gas cleaning is high. In addition to being able to maintain the above, it is possible to provide a forehead equipped with an extremely excellent gas cleaning device that can be used anywhere.
