Description

  The present invention relates to a relatively large-capacity dust collection deodorization apparatus installed in, for example, an air-conditioning duct, a ventilation duct, or the like in a store, factory, or various facilities.

  FIG. 13 is a diagram schematically showing an installation form of the conventional dust collector 100. Air induction ducts 52 such as air-conditioning ducts and ventilation ducts installed in facilities where an unspecified number of people gather, such as pachinko parlors, suck in dirty air in the room 50 by a blower 51 provided in the middle of the duct. The dust device 100 is passed through and the purified air is returned to the room 50. The dust collector 100 is installed alone on the flow path of the circulation type air induction duct 52, or is provided with a ventilation device or an air conditioner.

FIG. 14 is a side view schematically showing a conventional example of the dust collector 100 disclosed in Patent Document 1 and the like. When dirty air containing dust or the like flows from the air inlet (see gray arrows), air molecules withstand a high voltage of about +10 kV applied to the high voltage electrodes 112 such as a plurality of tungsten wires arranged in parallel. As a result, dust is positively charged. In the dust collector, a plurality of flat plate-like low voltage electrodes 113 to which a low voltage of about +5 kV is applied and a plurality of grounded plate-like ground electrodes 111 are alternately arranged in parallel along the flow direction. To form an electric field. When the positively charged dust flows into the dust collecting portion, it is adsorbed to the relatively negative ground electrode 111 by the Coulomb force along the electric field. The low voltage electrode 113 and the ground electrode 111 are usually made of aluminum foil.
JP 7-299385 A

The following problems can be pointed out in the prior art.
When the dust collector 100 is used for a certain period of time, dust or the like mainly adheres to the ground electrode 111 of the dust collector, and the air cleaning efficiency is lowered. Therefore, it is necessary to clean the dust collecting portion to which dust or the like is adhered, but the cleaning is performed by the following operations (i) to (iv).
(I) Remove the dust collector 100 from the air induction duct 52.
(Ii) The dust collector 100 is immersed in a strong alkaline aqueous solution for a predetermined time to peel off and remove the attached dust.
(Iii) A strong alkaline aqueous solution is naturally contaminated and is neutralized with a neutralizing agent and then discarded in sewage.
(Iv) The dust collector is washed and dried, and then attached to the air induction duct 52.
The above work has the following problems a to d.
(a) Strongly alkaline aqueous solutions and neutralizing agents are expensive.
(b) Both are laborious operations.
(c) If it is repeatedly immersed in a strong alkaline aqueous solution, the electrode of the aluminum foil to which dust adheres becomes gradually thinner and unusable, and it is necessary to replace it with a new one.
(d) For example, even in a small-scale pachinko parlor, since about 30 dust collectors are actually installed, the replacement cost becomes very high.
In addition to the above a to d, the dust collector 100 does not have a function of removing odors attached to dirty air.

  In view of the above problems, the present invention eliminates the need for strong alkali cleaning in the dust collector installed on the flow path of the air induction duct, thereby eliminating work burdens and work costs and reducing electrode life. The purpose is to extend the cost and to add a deodorizing function. In other words, an object of the present invention is to provide a dust collection and deodorization apparatus that solves the above problems.

  In the dust collection deodorizing apparatus according to claim 1, a belt-like suction paper is stretched in the paper feed direction perpendicular to the flow direction in the housing, and the belt-like suction paper is rotated by a mounting roller installed at one end. It is wound as a roll paper that is mounted as possible, and can be wound by driving a motor roller installed at the other end. A high-voltage electrode to which a high voltage is applied and a low-voltage electrode to which a low voltage is applied are disposed between the intake port and the strip-shaped suction paper, while the ground electrode to be grounded is disposed between the strip-shaped suction paper and the exhaust port. The It is preferable that the distance between the ground electrode and the belt-like suction paper is close enough that the paper feeding operation of the belt-like suction paper is not hindered. Accordingly, the belt-like adsorbing paper is in a state of being substantially in contact with the ground electrode due to the pressure of the flow. When the dust charged by the high voltage electrode flows to the vicinity of the belt-like adsorbing paper, it is attracted by the electric field between the low-voltage electrode, the ground electrode and the belt-like adsorbing paper, and is adsorbed on the belt-like adsorbing paper and deposited on the surface. As a result, the dust does not pass through the belt-like adsorption paper, and only the purified air passes. As a result, dust does not adhere to the ground electrode. Furthermore, in the deodorizing part, the titanium oxide acts as a photocatalyst by irradiating the titanium oxide coating plate with an ultraviolet lamp, and decomposes an organic substance which is an odor component. It also has a bactericidal action that kills bacteria in the air. Carbon dioxide and water produced by the decomposition reaction are harmless and odorless substances.

  In use, for example, a timer is set according to the period during which the limit amount of dust accumulates on the belt-shaped suction paper, and the motor roller is driven periodically to move the belt-shaped suction paper in the paper feed direction. Launch a new face. When all the roll paper has been used, the used belt-like suction paper wound on the motor roller may be discarded and a new roll paper may be set on the loading roll.

  In the dust collection deodorizer of the present invention, it is not necessary to clean the electrodes. Therefore, the burden of the cleaning work and the cost of the cleaning agent can be remarkably reduced, and the life of the electrode can be extended because the electrode is not consumed.

  The dust collection and deodorization apparatus according to claim 2 is the apparatus of claim 1, wherein the titanium oxide coating plate has a V-shaped cross section disposed so as to extend along the paper feed direction and open to the exhaust port side. An ultraviolet lamp is disposed along the titanium oxide coating plate. Thereby, the deodorizing part is arrange | positioned over the whole sending area | region, and the whole air from which the dust was removed can be deodorized. In particular, by forming a V-shaped cross section that opens to the exhaust port side, the air flow can be smoothly directed to the exhaust port side without obstructing the air flow.

  According to a third aspect of the present invention, there is provided a dust collecting and deodorizing apparatus according to the first or second aspect, wherein a suitable motor roller control device is provided. This control device receives the output signal of the first photoelectric sensor that monitors the degree of dirt on the belt-like suction paper, that is, the degree of dust adsorption, and controls the start of driving of the motor roller based on this signal. If the output signal of the first photoelectric sensor exceeds a preset value, the motor roller is driven to move the belt-like suction paper in the paper feed direction. Further, marks that can be detected by the second photoelectric sensor are provided at regular intervals on the belt-like suction paper, and the control device receives the output signal of the second photoelectric sensor that has detected the mark. Stop the motor roller. If a mark is attached so as to correspond to the feeding amount (corresponding to the stretched length) of the belt-like suction paper, one new belt-like suction paper is automatically fed.

  As a result, the belt-like suction paper is fed in accordance with the degree of dust accumulation, so that it is possible to appropriately cope with fluctuations in the amount of dust and the belt-like suction paper can be used without waste.

  In the dust collecting deodorization apparatus according to the fourth aspect, the substantially rectangular parallelepiped housing is configured by combining the receiving case and the cassette case, and the cassette case can be detachably fitted inside the receiving case. The cassette case is provided with a loading roller for loading roll paper, a belt-like adsorbing paper tensioning means, a winding motor roller, and a ground electrode, while the receiving case has a low voltage electrode and a high voltage electrode. And are installed.

  As a result, when all of the belt-shaped suction paper is used, the roll paper can be easily replaced by removing the used cassette case from the receiving case and replacing it with another cassette case pre-set with roll paper. As a result, the work load of roll paper replacement is reduced.

  The dust collection and deodorization apparatus according to claim 5 is the apparatus of claim 4, wherein the titanium oxide coating plate has a V-shaped cross section arranged so as to extend along the paper feed direction and open to the exhaust port side. An ultraviolet lamp is disposed along the titanium oxide coating plate. Thereby, the deodorizing part is arrange | positioned over the whole sending area | region, and the whole air from which the dust was removed can be deodorized. In particular, by forming a V-shaped cross section that opens to the exhaust port side, the air flow can be smoothly directed to the exhaust port side without obstructing the air flow.

  A dust collection and deodorization apparatus according to a sixth aspect is the apparatus according to the fourth or fifth aspect, wherein first and second photoelectric sensors and a motor roller control device similar to those of the second aspect are provided. As a result, the belt-like suction paper is fed in accordance with the degree of dust accumulation, so that it is possible to appropriately cope with fluctuations in the amount of dust and the belt-like suction paper can be used without waste.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(1) First Embodiment FIG. 1 is a schematic partially cutaway perspective view of a dust collection deodorizing apparatus 1 according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view along the front-rear direction of the dust collection deodorizer 1 of FIG. 3A, 3B, and 3C are an A sectional view, a B sectional view, and a C sectional view, respectively, of FIG. The dust collection deodorization apparatus 1 is installed so as to be interposed on a flow path of an air induction duct (hereinafter simply referred to as “duct”) shown in FIG. For convenience of explanation, right and left front and back are shown in the figure, but this does not limit the direction in which the dust collection deodorizer 1 is attached to the duct.

  In FIG. 1, the upward arrow indicates the direction of air flow when attached to the duct. In the example shown in the figure, the dust collection deodorization apparatus 1 includes a substantially rectangular parallelepiped casing 16, and the intake ports are respectively provided on two surfaces (the lower surface and the upper surface in FIG. 1) that are spaced apart from each other and perpendicular to the flow direction. 16a and the exhaust port 16b are opening (refer FIG.2 and FIG.3 (B)). The gray upward arrow indicates the flow of dirty air containing dust before flowing into the intake port 16a of the apparatus 1, while the white upward arrow is cleaned out of the exhaust port 16b of the apparatus 1. Shows the air flow.

  In the housing 16, a plurality of linear high voltage electrodes 12a to which a high voltage of about DC +10 kV, for example, is applied to charge the dust, and a plurality of linear shapes to which a low voltage of, for example, about DC +5 kV, is applied. The low-voltage electrode 13a and the mesh-like ground electrode 11a to be grounded are respectively stretched in a direction perpendicular to the flow direction. The plurality of linear high-voltage electrodes 12a are stretched between a pair of high-voltage electrode terminal blocks 12b and 12c respectively installed at the front end and the rear end of the bottom of the casing 16, and the plurality of linear low-voltage electrodes 13a Is stretched between a pair of low-voltage electrode terminal blocks 13b and 13c installed at the front end and the rear end of the bottom of the casing 16, respectively. Furthermore, a planar ground electrode 11a in which wires are assembled in a net shape is stretched in the ground electrode terminal frame 11b. The terminal blocks 12b, 12c, 13b, 13c and the terminal frame 11b are connected to predetermined power supply lines and ground lines (not shown), respectively.

  Further, a belt-like suction paper 21a is stretched in the housing 16 in parallel with the electrodes 11a, 12a and 13a. As shown in FIGS. 2 and 3, the high voltage electrode 12a and the low voltage electrode 13a are positioned between the belt-shaped suction paper 21a and the intake port 16a, and the low voltage electrode 13a is positioned between the belt-shaped suction paper 21a and the high voltage electrode 12a. On the other hand, the ground electrode 11a is located between the strip-shaped suction paper 21a and the exhaust port 16b. The distance between the belt-like suction paper 21a and the ground electrode 11a is much shorter and closer than the distance between the belt-like suction paper 21a and the low-voltage electrode 13a.

  The dust in the air flowing in from the intake port 16a is charged by the discharge of the high voltage electrode 12a, and further flows to the vicinity of the low voltage 13a, the ground electrode 11a is generated by the electric field formed between the low voltage electrode 13a and the ground electrode 11a. As a result, it is accelerated and attracted and deposited on the belt-like suction paper 21a. Thus, the air from which the dust has been removed passes through the belt-like adsorbing paper 21 a and the ground electrode 11 a and travels toward the deodorizing unit 30.

  For example, the belt-like adsorbing paper 21a is selected to have a thickness of about 30 to 50 μm and have air permeability that allows only air to pass smoothly without passing dust.

  The direction in which the belt-like suction paper 21a is stretched is perpendicular to the flow direction, and this direction is referred to as the “paper feed direction”. The belt-like adsorbing paper 21a is fed out from the roll paper 21 mounted at one end in the paper feeding direction in the housing 16. As shown in FIG. 2, the roll paper 21 is obtained by winding a belt-like suction paper 21a around a cylindrical core 21b, and is rotatably mounted on a cylindrical mounting roller 14a. As shown in FIGS. 1 and 3A, the intermediate portion of the mounting roller 14 a penetrates the inside of the core 21 b of the roll paper 21. Then, both ends of the mounting roller 14 a are passed through and supported by cylindrical mounting roller bearing portions 16 c protruding from the left and right side surfaces of the housing 16, so that the mounting roller 14 a is installed in the housing 16. The mounting roller 14 a is fixed to the housing 16 using a fixing pin 14 e so as not to rotate with the rotation of the roll paper 21.

  A cylindrical motor roller 15a is installed at the other end of the belt-like suction paper 21a in the paper feeding direction to wind up the belt-like suction paper 21a. A cable (not shown) from a control device for driving and stopping the rotation is connected to the motor roller 15a. As shown in FIG. 2, the motor roller 15a penetrates the inside of the cylindrical winding core 14d. Since the winding core 14d and the motor roller 15a are fitted with an appropriate frictional force, the winding core 14d rotates together with the motor roller 15a. As shown in FIGS. 1 and 3C, the shaft 15e of the motor roller 15a is passed through and supported by a cylindrical motor roller bearing portion 16d projecting from the left and right side plates of the housing 16, so that the motor roller 15a is supported. Is installed in the housing 16. When the motor roller shaft 15e is fixed with the holding bolt 15b, the motor roller 15a can be rotated. The front end of the belt-like suction paper 21a is fixed on the outer periphery of the winding core 14d by means such as adhesion or sticking.

  As shown in FIG. 2, the belt-like suction paper 21a is stretched so as not to be loosened by the pair of guide rollers 14b and 14c. These guide rollers 14b and 14c are rotatably installed so as to be bridged between the left and right side plates. One guide roller 14b is installed at a position immediately after being fed from the mounting roller 14a, and the other guide roller 14c is installed at a position immediately before being wound around the motor roller 15a.

  As dust accumulates on the belt-like adsorbing paper 21a, the air cleaning efficiency is lowered and the duct feeding efficiency is also lowered. Therefore, the belt-like adsorbing paper 21a is periodically moved once in the paper feeding direction. Set a new face. At this time, for example, the motor roller 15a is periodically rotated by a timer or the like to wind the belt-like suction paper 21a on the winding core 14d. The moving length for one time substantially corresponds to the length of the belt-like suction paper 21a, that is, the length between the guide rollers 14a and 14c.

  As shown in FIGS. 1, 2 and 3B, the deodorizing unit 30 is installed between the mesh-shaped ground electrode 11a and the exhaust port 16b, and is disposed between the pair of ultraviolet lamps 31a and 31b. The titanium oxide coating plate 32 is provided. Preferably, the titanium oxide coating plate 32 is arranged so that the longitudinal direction thereof is along the paper feeding direction. The titanium oxide coating plate 32 preferably extends over the entire longitudinal direction of the ground electrode 11a. Thereby, a deodorizing process can be performed with respect to all the air from which dust was removed. In the example shown in the figure, the shape of the titanium oxide coating plate 32 has a V-shaped cross section opened to the exhaust port 16b side. Both ends of the titanium oxide coating plate 32 in the front-rear direction are supported by being joined to support members 33 a and 33 b that are spanned between the left and right side plates of the housing 16. Both ends of the supporters 33a and 33b are fixed to the inside of the left and right side plates of the housing 16. Further, a pair of rod-shaped ultraviolet lamps 31 a and 31 b are arranged along both sides of the titanium oxide coating plate 32. The ultraviolet lamps 31 a and 31 b preferably extend over the entire longitudinal direction of the titanium oxide coating plate 32. Thereby, the deodorizing effect can be produced uniformly. Depending on the shape of the titanium oxide coating plate 32, one ultraviolet lamp may be used. When the titanium oxide coating plate 32 is irradiated by the ultraviolet lamps 31a and 31b, it acts as a photocatalyst that decomposes organic substances that are odorous components in the air. Sterilize airborne bacteria. And the air which passed the deodorizing part 30 flows out from the exhaust port 16b. The longer the contact time between titanium oxide and air and the larger the contact area, the greater the deodorizing effect. Therefore, the titanium oxide coated plate 32 having a V-shaped cross section is formed using a corrugated plate instead of a flat plate. May be.

(2) Other Example of First Embodiment FIG. 4 is a schematic partially cutaway perspective view of a dust collection deodorizing apparatus 1 according to another example of the first embodiment. FIG. 5 is a perspective view showing an example of the roll paper 21 used in the dust collection deodorization apparatus 1 of FIG. FIG. 6A is a cross-sectional view along the front-rear direction of the dust collection deodorizer 1 of FIG. 6B is a cross-sectional view taken along the line D in FIG. 6A.

  Transmission type photoelectric sensors 18a and 18b each composed of a light emitting unit and a light receiving unit are respectively installed on the upper side and the lower side so as to face each other with the belt-like suction paper 21a interposed therebetween. The photoelectric sensor 18a is attached to a support 19b extending from the side plate of the housing 16 to above the ground electrode 11a, and the photoelectric sensor 18b is attached to a support 19c extending from the side plate of the housing 16 to below the belt-like suction paper 21a. ing. A light beam such as infrared light from the light emitting unit is received by the light receiving unit, and the light intensity is converted into an electrical signal and output. The output electrical signal is transmitted to a control device (not shown). This output signal corresponds to the degree of contamination on the belt-like suction paper 21a. As dust accumulates on the belt-like suction paper 21a, the intensity of light transmitted through the belt-like suction paper 21a decreases, and the output signal changes. Accordingly, the value of the output signal corresponding to the limit of the stain on the belt-like suction paper 21a is set in advance, and monitoring is performed to detect whether or not the set value has been exceeded and to determine when to perform the paper feeding operation.

  If the control device detects that the set value is exceeded by the output signals from the first photoelectric sensors 18a and 18b, the control device outputs a signal for driving the motor roller 15a. As a result, the motor roller 15a rotates and winds up the belt-like suction paper 21a. On the other hand, a new belt-like suction paper 21 a is fed out from the roll paper 21.

  FIG. 5 is an example of the roll paper 21 used in this embodiment. On the surface of the belt-like suction paper, marks 21c are attached at regular intervals by printing, for example. The mark 21c can be read and detected by the second photoelectric sensor 17 shown in FIG. The photoelectric sensor 17 is attached to a support 19a extending from the side plate of the housing 16 to above the ground electrode 11a. The reflective photoelectric sensor 17 emits a light beam such as infrared light toward the surface of the belt-like suction paper 21a, and detects the presence or absence of the mark 21c by receiving the reflected light from the surface. The electrical signal output from the photoelectric sensor 17 is also transmitted to the control device. When the motor roller 15a rotates and the paper feed is started and then receives a signal detecting the mark 21c from the photoelectric sensor 17, the control device outputs a signal for stopping the motor roller 15a. As a result, the motor roller 15a stops rotating. In this way, a new belt-like suction paper 21a is set.

FIG. 8 is an exploded perspective view of the dust collection deodorizing apparatus 2 of FIG. FIG. 9 is a cross-sectional view along the front-rear direction of the air cleaner 2 of FIG. FIGS. 10A, 10B, and 10C are an A sectional view, a B sectional view, and a C sectional view, respectively, of FIG. In addition, the same code | symbol etc. are used about the same component as 1st embodiment.

  In the dust collection deodorizing apparatus 2, the casing 16 is composed of two separable case parts. The outer receiving case 160 is attached to the duct. A detachable cassette case 161 can be fitted inside the receiving case 160. By fitting the cassette case 161 to the receiving case 160, a substantially rectangular parallelepiped casing 16 is formed. The housing 16 has an intake port 16a and an exhaust port 16b that are opened on two surfaces that are spaced apart from each other and perpendicular to the flow direction (see FIGS. 9 and 10B).

  As shown in the exploded perspective view of FIG. 8, at one end of the cassette case 161 in the paper feeding direction, a cylindrical mounting roller 14a for rotatably mounting the roll paper 21 wound with the belt-like suction paper 21a is installed. ing. As shown in FIGS. 9 and 10A, the mounting roller 14a has an intermediate portion that penetrates the roll paper 21, and both ends thereof project outward from the circular holes in the left and right side plates of the cassette case 161.

  The belt-like suction paper 21 a fed out from the roll paper 21 is stretched along the paper feeding direction in the cassette case 161. As this tensioning means, rotatable guide rollers 14 b and 14 c are provided so as to be bridged between the left and right side plates of the cassette case 161.

  A cylindrical motor roller 15a for winding the belt-like suction paper 21a is installed at the other end in the paper feeding direction in the cassette case 161. As shown in FIGS. 9 and 10C, the motor roller 15a passes through the winding core 14d, and the winding core 14d rotates together with the motor roller 15a.

The ultraviolet lamps 31 a and 31 b preferably extend over the entire longitudinal direction of the titanium oxide coating plate 32. Thereby, the deodorizing effect can be produced uniformly. Depending on the shape of the titanium oxide coating plate 32, one ultraviolet lamp may be used. When the titanium oxide coating plate 32 is irradiated by the ultraviolet lamps 31a and 31b, it acts as a photocatalyst that decomposes organic substances that are odorous components in the air. Sterilize airborne bacteria. And the air which passed the deodorizing part 30 flows out from the exhaust port 16b. The longer the contact time between titanium oxide and air and the larger the contact area, the greater the deodorizing effect. Therefore, the titanium oxide coated plate 32 having a V-shaped cross section is formed using a corrugated plate instead of a flat plate. May be.
