Description

  The present invention relates to a polluted air purification apparatus using a photocatalyst comprising a filter unit that purifies contaminated air by the action of a photocatalyst and a filter chamber that houses the filter unit.

The photocatalytic filter currently on the market is mainly composed of an alumina ceramic porous body with a UV-responsive photocatalytic layer made of titanium oxide (titanium dioxide: TiO ² ) formed on the surface of the base material. Yes. In addition, the anatase type with high photocatalytic performance is mainly used for titanium oxide. Titanium oxide uses fine particles having a small particle size, particularly nanoparticles having a particle size of several nanometers in order to increase the specific surface area of the photocatalytic active layer and enhance the decomposition and removal ability (see Patent Document 1).

  As this photocatalytic filter, for example, a base material is a material that is “plastic or metal or glass alone, or a composite of two or more materials selected from these groups, and is at least more brittle and fractured than alumina ceramic”. (See Patent Document 1) is proposed. According to this, a photocatalytic filter that is harder to break than a photocatalytic filter based on at least alumina ceramic can be obtained. Furthermore, it is desirable to obtain a light and thin photocatalytic filter that is stronger and stronger, can be formed in any shape and size, and is light.

And as a filter unit which can utilize the said photocatalyst filter, the plate-shaped photocatalyst filter in which the titanium oxide film | membrane with a film thickness of 1 micrometer or less is formed in the surface layer of ceramic frame | skeleton is comprised so that an ultraviolet lamp may be inserted | pinched. A photocatalyst deodorization apparatus (see Patent Document 2) has been proposed. According to this, by disposing the photocatalytic filter on both surfaces of the ultraviolet lamp, the performance of the filter can be maximized and deodorization can be performed efficiently.
In this photocatalyst deodorization apparatus, an example of the form of the filter unit has been proposed, but no proposal has been made about the structure of the filter chamber when the filter unit is applied to a large contaminated air purification apparatus. . For example, an application form in a case where contaminated air should be treated on a relatively large scale such as a garbage disposal site has not been studied.

  On the other hand, in a garbage disposal site, it is not a combustion furnace and a combustion soot system that processes soot discharged from the combustion furnace, but air is also easily contaminated in the building, and the environment of the worker is likely to deteriorate. . Moreover, if the contaminated air is discharged to the outside, the surrounding environment will be contaminated. For example, leakage gas generated in the scavenging system from the garbage pit (temporary garbage storage), and leakage gas in the combustion smoke system in the final smoke treatment plant (combustion building) include toxic gases such as dioxin and PCB. ing. Therefore, in order to improve the so-called working environment and surrounding environment, there is a demand for a device for purifying contaminated air.

  On the other hand, conventionally, in garbage disposal sites, polluted air is purified by a filter using activated carbon as an adsorption filter for collecting pollutants. That is, activated carbon is mainly used for purification devices arranged in-line in the scavenging system led from the garbage pits to the combustion furnace, and for air circulation type purification devices arranged to clean the air in buildings such as combustion buildings. The filters that have been used have been used. However, in such a purification apparatus such as a garbage disposal site using activated carbon, the volume of processing air increases, so the apparatus becomes large and heavy, and a large amount of filter elements (such as activated carbon) must be replaced for maintenance. A great deal of labor and expense is required. Therefore, not only the initial cost becomes high, but also the running cost becomes large.

  As shown in FIGS. 1 and 13, the space of the filter chamber 20 is divided into three by one filter unit 10 housed in the filter chamber 20 and the other filter unit 10. According to this, it is possible to appropriately ensure a sufficient ventilation space where the ventilation resistance is not as much as possible with respect to the air flow described later.

  An intermediate space 33, which is a three-divided space of the filter chamber 20 and is between the one and the other filter units 10, 10, is provided as a ventilation space on the intake side of contaminated air. It is a space through which air on the contaminated side flows directly through the air inlet 31 and the inlet vent 32.

  Then, the one side space 35a and the other side space 35b, which are divided into three sides of the filter chamber 20, pass through either the one or the other filter unit 10, 10 from the suction side ventilation space 33. Thus, it is provided as a ventilation space on the purification discharge side where the contaminated air is purified and discharged. As described above, by providing a space through which air flows in the polluted air purification device using a photocatalyst, a rational configuration that can reduce the ventilation resistance as much as possible and reduce the energy consumption by the blower as much as possible. It has become.

  According to the polluted air purifying apparatus using the photocatalyst according to the present invention, the action of the photocatalyst is used, so that harmful substances can be decomposed and detoxified and discharged, and environmental pollution can be prevented. And since a pollutant is decomposed | disassembled and purified, compared with the method of collecting a pollutant with a filter, a pressure loss does not rise and since ventilation resistance is small, the energy consumption by ventilation can be suppressed. Moreover, since the filter performance is regenerated by decomposing and purifying the pollutants, the purification performance can be appropriately maintained over a long period of time.

  In the embodiment shown in FIG. 1, the filter unit 10 is configured by arranging a panel-like filter cartridge 1 carrying a photocatalyst and a light source cartridge 2 on which the photocatalyst acts in an adjacent state. Thus, by making the catalyst filter and the light source, which are components of the filter unit 10, into a cartridge, the filter unit 10 itself can be configured appropriately and easily, and maintenance management can be easily performed.

  Further, in the embodiment of FIG. 1, the filter unit 10 is configured by arranging a filter set constituted by the filter cartridge 1 and the light source cartridge 2 in a plurality of stages. In this embodiment, the filter set 10 is arranged in two stages, and the cleaning efficiency for purifying contaminated air can be increased. Furthermore, the cleaning efficiency as an air purifier can be increased as much as possible by providing the filter set 10 in multiple stages.

  Further, each of the one and the other filter units 10 and 10 is arranged as a set in the transverse direction with reference to the ventilation direction in which the contaminated air is sucked into the filter chamber 20, and the two sets of filter units. Inspection ports 22 are provided on both side surfaces of the filter chamber 20 so that 10 and 10 can be attached and detached from both sides of the filter chamber 20 in the lateral direction.

That is, the form example of FIG. 13 has a form in which the filter unit 10 is vertically placed and a plurality of single chambers 20a are stacked in the vertical direction.

  According to this, the air flow of the contaminated air 60 and the purified air 70 is basically a downward flow (down flow). In the case of downflow, it becomes the same direction (downward air flow) as the direction of dust that settles down and accumulates in the lower part, making it easy to prevent dust from re-scattering and collecting dust efficiently. it can. And the dust which settles is easy to accumulate | store in the lower end part of the intermediate space 33 of the chamber single-piece | unit 20a of the lowest end, and it is easy to perform maintenance management.

It is shown that. In the case of a vertically-arranged structure as shown in FIG. 13, dust that is a contaminant is easily collected at the lower end of the intermediate space 33 of the lowermost chamber unit 20a. Moreover, it is also a part where sewage (contaminant) generated when the filter cartridge 1 is washed with water is finally accumulated. Contaminants collected in such a manner can be discharged appropriately and easily by providing a passage such as a duct communicating with the lower end of the intermediate space 33 of the lowermost chamber unit 20a. It has become a merit.

Further, as in the embodiment shown in FIGS. 7 to 12, the filter chamber 20 configured by connecting a plurality of single chambers 20 a is used as one enlarged chamber unit, and a plurality of the enlarged chamber units are arranged. By being comprised, the further enlargement of the purification apparatus of the polluted air using a photocatalyst can be achieved. The embodiment shown in FIGS. 7 to 12 relates to a device configured horizontally, and is configured to be stacked in two layers in the vertical direction, but can be further stacked in multiple layers and configured in a vertical configuration.

Next, a detailed description will be given of a first embodiment configured in a horizontal position of a contaminated air purifying apparatus using a photocatalyst according to the present invention based on the attached drawings (FIGS. 1 to 6 and 13).
In this embodiment, as shown in FIG. 1, a plurality of chambers 20a are connected in the horizontal direction.

  As shown in FIG. 1, the filter unit 10 according to the present embodiment includes a filter cartridge 1 carrying a photocatalyst and a light source cartridge 2, and the filter cartridge 1 and the light source cartridge 2 are configured separately. The two may be integrated with one casing. Of course, the filter unit 10 may be configured as one cartridge by fixing the photocatalytic filter and the light source in one casing. The light source cartridge 2 can be provided by a structure in which a plurality of ultraviolet lamps are held in one casing in a state where they are arranged in parallel. In this way, the cartridge can be attached and detached appropriately and easily. Of course, the light source of the light source cartridge 2 is not limited to the above-described ultraviolet lamp, and other light emitting devices such as LEDs can be used.

  In the present embodiment, the filter chamber 10 is configured so that the filter unit 10 is held flat in the upper and lower mounting portions, can be inserted and mounted in the horizontal direction, and can be pulled out and detached in the horizontal direction. In the filter chamber 20, the space between the filter units 10 at the two upper and lower mounting portions is provided as a ventilation space 33 on the suction side of the contaminated air 60, and the filter units 10 mounted at the two upper and lower mounting portions. The upper space (one side space 35 a) and the lower space (the other side space 35 b) that are both side spaces are provided as ventilation spaces 35 a and 35 b on the purification exhaust side of the contaminated air 60.

  According to this, as shown in FIG. 1, the contaminated air 60 that has passed through a roll filter device 40 and an inlet vent 32 at the front stage of the filter chamber 20, which will be described later, is located in an intermediate space (suction side) in the vertical direction of the filter chamber 20. Are introduced into the ventilation space 33). Then, while passing through the filter unit 10, the contaminant is decomposed and purified by the action of the photocatalyst, and the purified air 70 is discharged to the one side space 35 a and the other side space 35 b of the filter chamber 20. And it passes through the exit ventilation | gas_flowing part 36 where the one side space 35a and the other side space 35b merge, and is discharged | emitted outside.

  Here, the cross-sectional area as a ventilation path which is the size of the suction-side ventilation space 33 and the purification-discharge-side ventilation spaces 35a and 35b is such that the ventilation resistance is not as much as possible with respect to the required processing air volume of the contaminated air. Is set to be large enough. That is, in order to appropriately secure a time for decomposing the pollutant by the photocatalyst, the ventilation path is set sufficiently large so that the flow velocity of the air flowing through the ventilation space is sufficiently low. For example, the flow rate may be set in the range of 0.2 m / s to 1.0 m / s. For dioxins that are required to be purified at a garbage disposal facility, the flow rate may be set to about 0.7 m / s, for example. As for the PCB, sufficient decomposition and purification can be performed by setting its flow rate to a lower speed, for example, about 0.3 m / s.

  As described above, according to the present invention, since the action of the photocatalyst is used, harmful substances can be decomposed, detoxified and discharged, and environmental pollution can be prevented. And since a pollutant is decomposed | disassembled and purified, compared with the method of collecting a pollutant with a filter, a pressure loss does not rise and since ventilation resistance is small, the energy consumption by ventilation can be suppressed. Moreover, since the filter performance is regenerated by decomposing and purifying the pollutants, the purification performance can be appropriately maintained over a long period of time. Although the filter cartridge 1 is contaminated on the surface of the filter, it can be easily regenerated by simply rinsing with water as a unique effect of the photocatalyst.

  Moreover, in the filter chamber 20 of this embodiment, it is formed in a box shape, and the filter unit 10 is held in a flat state. Further, both side portions of the filter unit 10 are provided so as to be fitted in a pair of grooves provided in the filter chamber 20 and slid to be attached / detached / held. For this reason, the weight of the filter unit 10 can be evenly received on both side portions thereof, and the filter unit 10 is appropriately held in the filter chamber 20, and the operator can easily hold it with both hands, and can easily insert and remove it for attachment and detachment. Can be done. Since it is easy to perform the work in this way, it is possible to prevent the filter cartridge 1 and the ultraviolet lamp 2 from being damaged when the operator accidentally drops them. Further, since the filter unit 10 is disposed at the upper and lower mounting portions, the suction side ventilation space 33 can be appropriately shared, and a plurality of filter units 10 can be efficiently and compactly arranged.

  Further, in this embodiment, each of the filter units 10 and 10 at the two upper and lower mounting portions is in the left and right directions with reference to the depth direction in which the contaminated air 60 is drawn into the filter chamber 20 from the near side. The two filter units 10 and 10 are arranged so as to be inserted and pulled out from both the left and right sides. The filter unit 10 and 10 can be attached and detached by opening the inspection door 21 and through the inspection port 22. According to this, since the filter unit 10 can be doubled in each stage, the processing air volume of contaminated air can be doubled. Further, the filter chamber 20 can be maintained from both the left and right sides, so that the work can be easily performed.

  Further, in the present embodiment, the depth direction (front-rear direction) in which a plurality of chamber units 20 a configured by unitizing the filter chamber 20 is away from the front, which is the direction in which the contaminated air 60 is sucked into the filter chamber 20. In addition, the suction side ventilation space 33 is connected so as to communicate with each other, and the purification exhaust side ventilation spaces 35a and 35b of the upper and lower contaminated air 60 are connected so as to communicate with each other. Thus, since it is unitized as the chamber single-piece | unit 20a, the magnitude | size as a whole of the filter chamber 20 can be easily adjusted and changed according to the process air volume of contaminated air.

  Reference numeral 40 denotes a roll filter device, which is contaminated upstream of the ventilation of the suction port of the filter chamber 20 so as to capture suspended particles in the contaminated air 60 before the contaminated air 60 is sucked into the filter chamber 20.
