[Technical field to which the invention belongs]
The present invention relates to an air purification device that removes the odor component or unnecessary particles from the air containing the odor component or floating particles.
[0002]
[Prior art]
An air deodorizing device disclosed in Japanese Patent Application Laid-Open No. 11-90163 includes a cylindrical device main body to which bad odor air is supplied, a cold water shower unit that is disposed above the device main body and injects cold water, and , At least one layer of a porous plate that is horizontally disposed under the cold water shower unit and has a large number of small holes for retaining water after showering, and a water storage tank for storing water dripped from the small holes of the porous plate Furthermore, the water storage tank is provided with a pump device that pumps the stored water therein to the shower unit, and a deodorant supply means that supplies a deodorant to the piping system to the shower unit. is there. Furthermore, this reference discloses that the total area of the small holes is set to be 40% or less of the porous plate area so that an aqueous layer of at least 15 mm or more is formed on the upper surface of the porous plate. Further, in this conventional example, it is disclosed that it is desirable that the diameter of the small holes is about 4 mm on average.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional example, a compound formed by a chemical reaction between, for example, an odor component and a deodorizing agent adheres to the small holes formed in the perforated plate, and the diameter of the holes is narrowed. There is a problem that it does not work.
[0004]
Further, when the conditions of each small hole are the same, a solution (liquid) containing a deodorant that passes through the small hole from the top to the bottom, and an air containing an odor component that passes through the small hole from the bottom to the top ( Gas) will select and pass through appropriate small holes, respectively, so that the contact status between the solution and the air will depend on the respective conditions, for example, the amount of water supplied, the wind pressure of air passing through, the speed, and the addition. It has a problem that it is difficult to estimate how it changes depending on the viscosity of the solution due to the deodorant.
[0005]
For this reason, this invention is providing the air purification apparatus which can perform the stable bubbling process, and can maintain the unit which performs this process easily while making the fall state of a solution and the bubble formation of air uniform. .
[0006]
[Means for Solving the Problems]
Accordingly, the present invention is configured such that air containing at least an odor component or suspended particles is supplied into a cylindrical duct, and a lower portion thereof is a water storage space, and is located above the suction portion. A bubbling processing unit that allows the air rising from the suction unit to pass through the solution containing deodorizing components as bubbles, and a shower ring that is located above the bubbling processing unit and that drops the solution onto the air rising from the bubbling processing unit In the air purifying apparatus comprising at least a processing unit, the bubbling processing unit includes a plurality of circular bubbling plates having a plurality of holes having different diameters, and a predetermined density between the bubbling plates. A cylindrical bubbling cell unit constituted by a filter arranged in a detachable manner is detachably arranged. Furthermore, it is desirable that the filter is formed by entwining fiber yarns made of synthetic resin so as to have a predetermined density.
[0007]
Therefore, according to the present invention, by providing a plurality of small holes having different diameters in the bubbling plate, it is possible to distinguish naturally from the holes through which the solution easily falls and the holes through which air easily passes. It becomes easy to grasp the contact state with air. In addition, by providing a filter provided at a predetermined density between each bubbling plate, the falling speed of the solution can be adjusted, and the contact time between the bubbles and the solution can be adjusted. Further, the bubbling cell unit including these can be freely attached and detached, thereby simplifying maintenance.
[0008]
In the present invention, the bubbling plate is formed with at least one first hole having a first diameter and a plurality of second holes having a second diameter smaller than the first hole. It is desirable. As a result, a solution having a large mass or density tends to fall through the first hole having a large diameter, and air having a small mass or density tends to rise through the second hole. It is easy to judge the contact situation.
[0009]
Furthermore, it is desirable that the second hole is inclined at a predetermined angle with respect to the axial direction of the bubbling plate. Furthermore, it is preferable that the inclination direction of the second hole is a circumferential direction of the bubbling plate. As a result, air bubbles rise in the spiral direction, so that the contact state between the solution and the bubbles can be improved.
[0010]
Further, it is desirable that the position of the first hole formed in each bubbling plate is arranged at a position that does not overlap with the air passing direction. As a result, the solution dropped on the uppermost bubbling plate is temporarily stopped on the next bubbling plate, so that a long residence time of the solution can be secured. As a result, since the amount of the solution to be supplied can be reduced, cost reduction can be achieved.
[0011]
Furthermore, an upper plate in which a plurality of third holes having a third diameter are formed may be disposed on the uppermost stage of the bubbling cell unit. Thus, the dropping time of the solution can be adjusted by setting the third diameter so as to store a predetermined amount of the solution after the showering process falling on the bubbling cell unit. Further, among the third holes, a predetermined number of holes are inclined at a predetermined angle in a predetermined direction, and a non-inclined hole for dropping the solution and an inclined hole for passing air are set. You may do it.

A drainage duct 13 for draining the solution staying in the water storage space 11 is provided at the lower end of the water storage space 11 below the suction portion 5, and is opened and closed by an on-off valve 14.
[0016]
Further, a bubbling cell unit 40 to be described below is provided above the suction unit 5, and a showering space 31 constituting the showering processing unit 3 is formed above the bubbling cell unit 40. Above the showering space 31, a shower device 33 having a plurality of injection nozzles 32 is provided, and a solution to which ozone is added is sprayed on the air that has passed through the bubbling cell unit 40. Odor components and excess particles are removed. The ozone amount is monitored by the flow meter 60. The amount of solution supplied to the shower device 33 is monitored by the flow meter 61. In this embodiment, ozone is used as the air purification agent, but the purification agent is not particularly limited to ozone.
[0017]
Then, the air purified through the bubbling processing unit 4 and the showering processing unit 3 is discharged to the outside through the duct 18. Note that a fan, a filter, and the like for discharging air may be provided in the duct 18. Further, pressure sensors 62 and 63 monitor the upper and lower sides of the bubbling processing unit 4.
[0018]
The signals from the pressure sensors 62 and 63, the signals from the flow meters 60 and 61, the signal from the water level meter 12, and the signal from the temperature sensor 64 are sent to a control unit (C / U) 65 for control. These signal values are monitored by the unit 65, and the flow rate control valve 10, the blower 7, the pump 15, and the ozone generator 17 are controlled so that the signal values fall within a predetermined value or a predetermined range. Is.
[0019]
In the present embodiment, the signal value is transmitted to the service center 67 via the remote device 66, where the signal value is monitored and the control signal is transmitted to the remote device so that optimum control can be performed. The information is transmitted to the control unit 65 via 66 and controlled.
[0020]
The bubbling cell unit 40 is, for example, as shown in FIG. 2, and has a cylindrical frame 41 having flange portions 42 and 43 to be connected to the showering processing unit 3 and the suction unit 5 at upper and lower ends. A plurality of bubbling plates 44 arranged perpendicular to the axial direction of the frame body 41, an upper plate 46 provided at the uppermost stage, a predetermined density between the bubbling plates 44 and between the bubbling plate 44 and the upper plate 46. And a lock filter 45 made of a synthetic resin yarn loaded in
[0021]
The bubbling plate 44 has a plate body 47 formed in a circular shape, solution dropping holes 48 having four predetermined diameters provided in the plate body 47, and an equal formation around the solution dropping holes 48. The plurality of air passage holes 49 are formed. In the present embodiment, the diameter of the plate body 47 is about 40 cm, whereas the solution dropping hole 48 is formed with a diameter of 5 cm, and the air passage hole 49 is formed with a diameter of 3 mm to 5 mm. The These numerical values are calculated and determined by the diameter of the duct 2, the supply amount of the solution, the viscosity of the solution, the pressure of the air, the purification level of the air, and the like. Further, adjacent bubbling plates 44 are arranged so as to be shifted by 45 ° so that the positions of the solution dropping holes 48 of the respective bubbling plates 44 do not overlap in the axial direction of the frame body 41.
[0022]
Furthermore, as shown in FIG. 4, the air passage hole 49 is formed to be inclined at a predetermined angle θ in a predetermined direction. In this embodiment, the bubbling plate 44 is formed to be inclined at an angle of 45 ° in the circumferential direction.
[0023]
Furthermore, the upper plate 46 may be the same as the bubbling plate 44 described above. However, as shown in FIG. 5, a cylindrical plate body 52 and holes 51 formed uniformly in the plate body 52 are provided. The plate comprised by may be sufficient. Of the holes 51 formed in the upper plate 46, a predetermined number of holes are inclined at a predetermined angle in a predetermined direction, a non-inclined hole for dropping the solution and an inclined hole for air passage. You may make it set to a hole.
[0024]
With the above-described configuration, the air to be purified (air containing odor components or unnecessary particles) sucked by the blower 7 is sent to the suction unit 5, and the pressure of the suction unit 5 and the showering processing unit The to-be-purified air rises to the bubbling processing unit 4 due to the differential pressure of 3. In the bubbling processing unit 4, the solution sprayed in the showering processing unit 3 stays on the upper plate 46 and sequentially falls on the bubbling plate 44.
[0025]
In the bubbling plate 44, the solution falls from the solution dropping hole 48 onto the next bubbling plate 44. The dropping speed at this time is determined by the size of the solution dropping hole and the density of the lock filter loaded between the plates. At the same time, the air to be purified rises as air bubbles from the air passage hole 49. However, since the air passage hole 49 is inclined in the circumferential direction, the air bubbles spirally rise in the solution. Will be. By the contact between the bubbles and the solution in this process, the cleaning agent contained in the solution and the odor components and unnecessary particles contained in the bubbles are removed by a chemical reaction. And the air which rose from the bubbling process part 4 is further purified by the solution sprayed from the shower apparatus 33, and is discharge | released outside via the duct 18. FIG.
[0026]
Further, the bubbling cell unit 40 is removed from the duct 2 and washed with high pressure after a predetermined time of work or when workability is lowered. And after performing a passing air volume and a static pressure test, it mounts | wears with the said duct 2 again. Thus, by making the bubbling cell unit 40 detachable with respect to the duct 2, maintenance of the bubbling cell unit 40 is facilitated.
[0027]
【The invention's effect】
As described above, according to the present invention, since the bubbling cell unit is made detachable, maintenance of the bubbling cell unit can be facilitated, so that the purification performance of the apparatus can be maintained.
[0028]
In addition, the bubbling plate that forms the bubbling cell unit is formed with a large-diameter solution drop hole and a small-diameter air passage hole, so it is easy to grasp the falling state of the solution and the rising state of the bubbles. Since the state can be made constant, the air purification ability in the bubbling process can be stabilized.
[0029]
Further, since the positions of the solution dropping holes are not overlapped in adjacent bubbling plates, the solution passing through one bubbling plate is held on the next plate, so that the falling speed of the solution can be suppressed. The amount of solution required for purification can be suppressed.
[0030]
Furthermore, since the filter formed by entwining a plurality of synthetic resin yarns between the plates is arranged at a predetermined density, the falling speed of the solution can be reduced. This also improves the contact state between the solution and the bubbles.
