Description

  The present invention relates to an air purification duct type hollow structure that removes contaminants from contaminated air and purifies the air.

  In recent years, there has been a growing interest in healthy and comfortable living and office environments. For example, in a building, there is a technology that removes pollutants contained in air that is taken into the building or air that is discharged outside the building by using a filter made of an adsorbent such as activated carbon, a photocatalyst, or a compounded material thereof. Proposed.

  However, when a filter is used for removing contaminants, pressure loss increases, and installation of a dedicated fan or the like is required. As a technique for avoiding this, Patent Document 1, for example, An apparatus (hereinafter referred to as “parallel plate apparatus”) that reduces pressure loss by arranging a flat plate made of a photocatalyst or a mixture of a photocatalyst and an adsorbent in parallel with the flow direction of contaminated air has been proposed. .

  In this parallel plate device, when an adsorbent is used, the adsorption site decreases as the adsorption progresses, and eventually breaks through.Before this situation, decompression regeneration, thermal desorption regeneration, chemical regeneration, It is necessary to regenerate by a method such as solvent regeneration, substitution regeneration, oxidative decomposition regeneration, or replacement with a new one.

  When using a photocatalyst, all organic substances can be oxidatively decomposed and finally decomposed into water and carbon dioxide. On the other hand, substances containing nitrogen and sulfur, such as nitrogen oxide (NOx), ammonia, and sulfur oxide (SOx), are oxidized to non-volatile nitrate and sulfate ions by photocatalytic reaction and removed from the air. However, since these products accumulate on the photocatalyst surface and cause performance deterioration, that is, catalyst poisoning, it is necessary to periodically remove these products.

  Therefore, in view of such circumstances, the present inventors have a hollow structure main body provided with an opening / closing portion on the wall surface, and are detachable in a state substantially parallel to the air flow direction inside the hollow structure main body. An air cleaning device having a pollutant removing member arranged is proposed, and a technique related to this is disclosed in Patent Document 2. According to this air cleaning device, the pollutant removing member can be freely removed, so that the pollutant removing member can be easily replaced and cleaned at an appropriate time.

  However, when NOx or SOx is oxidized and removed by the photocatalyst, the catalyst performance is often deteriorated due to the catalyst poisoning in a relatively short period of time, and the frequency of exchanging and cleaning the pollutant removing member is increased. Even if it is an easy task, the effort and time are considerable.

  Therefore, the present inventors will further research and respond easily and flexibly to changes in the number and arrangement of contaminant removal members while having the function of cleaning with the contaminant removal members installed. An air purifying apparatus having a cleaning function capable of achieving the above has been developed, and a technique related to this is described in Patent Document 3.

However, according to the air cleaning device, since the cleaning device is installed above the contaminant removing member, a part of the sunlight irradiated to the contaminant removing member from the ultraviolet transmissive top plate is blocked. Contaminant removal performance is reduced.
Furthermore, when the ultraviolet irradiation means is disposed on the ceiling, a cleaning device is disposed between the ultraviolet irradiation means and the contaminant removal member. For this reason, although it is possible to prevent the cleaning liquid discharged from the cleaning tube from scattering in the direction of the ultraviolet irradiation means as much as possible, a part of the ultraviolet rays irradiated from the ultraviolet irradiation means to the contaminant removal member is blocked by the cleaning pipe. Therefore, there is a concern that the pollutant removal efficiency may be reduced.

In such an air purifier, since not only tap water but also rain water can be used as a cleaning liquid, it is economical and can be installed outdoors where water supply facilities such as tap water are not provided. Have advantages.
However, when rainwater is used as a cleaning liquid, there is a risk of accelerating material degradation due to excessive cleaning due to prolonged rainfall. For this reason, when rainwater is used, it is necessary to introduce a system that adjusts the supply amount and supply timing of rainwater, which may result in a complicated apparatus configuration.

Further, in the above air purification apparatus, since the pollutant concentration of the air to be cleaned is higher on the inlet side than the outlet side which is the downstream side of the flow of contaminated air, the pollutant to be removed Both the amount and the product accumulation amount on the photocatalyst surface are larger on the inlet side.
For this reason, when the cleaning process is performed on the inlet side, excessive cleaning is performed on the outlet side where the accumulation amount is small, and the life of the contaminant removing member is shortened. In addition, the running cost for cleaning increases more than necessary.

  When a photocatalyst is used as the pollutant removing member 4, the duct-type hollow structure 2 and one or a plurality of openings are provided in the duct-type hollow structure 2 at positions where sunlight can be taken, and light that blocks the openings. It is suitable to comprise with the permeable member 9 (9a-9e) (FIG. 4). By comprising in this way, sunlight can be taken in in the said air purifying duct type | mold hollow structure 1. FIG. By making part or the whole of the opening openable and closable, maintenance such as replacement of internal materials is facilitated. For example, it may be of any form, such as one that opens and closes the opening with a pivoting or sliding door member, and one that opens and closes the opening with a lid member.

When a photocatalyst is used as the pollutant removing member 4 and the duct type hollow structure 1 is used in the vertical direction, the lower duct type hollow structure 1 is not provided with an opening, so that sunlight is not emitted. A configuration in which the light source is covered with ultraviolet irradiation means without receiving light may be employed.
Further, a part or the whole of the bottom surface of the upper duct type hollow structure is constituted by the light transmissive member 9, and the lower duct type hollow structure is provided with an opening to be closed by the light transmissive member 9, and used in the upper stage. Part of light irradiation from sunlight or light irradiation means may be reused in the lower stage. At this time, it is preferable to provide a light irradiation means in the lower duct type hollow structure 2.

The pollutant removing member 4 accommodated in the duct type hollow structure 2 is fixed to a part or the whole of at least one of a photocatalyst, a material having a catalytic function, and an adsorbent by coating or baking on the contained form or surface. Any of the forms may be used.

Furthermore, the photocatalyst is supported on a ceramic substrate such as tile, ceramic, cement, glass, diatomaceous earth, calcium silicate plate, etc. by a high-temperature baking type, low-temperature drying type, coating method, etc. included.

The adsorbent may be any material as long as it has at least an adsorption function. For example, the adsorbent may have a catalyst function such as oxidation-reduction.
Examples of materials having such an adsorption function include zeolite, silica gel, zirconia, ion exchange materials, alumina-based adsorbents, metal complex-based adsorbents, inorganic adsorbents such as ceramics, activated carbon, ion-exchange materials, and chelate. Organic adsorbents such as resins are applicable.
The adsorbent includes those coated or impregnated with a gas reaction component for removing a specific gas (for example, a potassium hydroxide solution for removing carbon dioxide).

As shown in FIG. 5, the pollutant removing member 4 can have an appropriate structure as long as it can be installed in the duct type hollow structure 2, but a plurality of standing uprights standing in the vertical direction can be used. A structure having a plate portion is preferable.
The standing plate portion is not limited to a simple flat plate structure (4a), but may be a pleated structure, a corrugated structure, a mountain-valley structure, or an uneven structure (4c).
Further, the shape and quantity of the groove of the contaminant removing member fixing portion 5 and the mounting angle with respect to the bottom member 3 are appropriately changed as shown in 5a and 5b of FIG. The lower part can be inserted into the groove of the fixed part 5 to adjust the angle with respect to the air flow direction.
Furthermore, the contaminant removal member 4 can be produced by baking or applying a photocatalyst to a pleated or corrugated ceramic material, and can be installed on the fixing portion 5 (see FIG. 5).
In addition, as a layout, it is preferable to arrange | position substantially parallel to the distribution direction of air, and this can suppress a pressure loss.

  The fixing portion 5 of the contaminant removing member 4 described above may be configured to be mounted by forming a locking groove, a locking piece or the like at the attachment position of the contaminant removing member 4, or a structure mounted by a dedicated clip. .

When the pollutant removing member bottom plate 17 is arranged under the light irradiation means 11, the upper surface of the pollutant removing member bottom plate 17 is irradiated with light in addition to the standing pollutant removing member 4, and as a result, pollutant removal is performed. The contact area for the upper surface of the member bottom plate 17 is increased, and the photocatalytic function is improved.
On the other hand, when the pollutant removing member bottom plate 17 is disposed on the light irradiation means 11, the contact area of the bottom surface of the bottom plate 17 is increased. However, if the sunlight is not irradiated, the contaminant removing member 4 (standing portion) is not irradiated with ultraviolet rays, so that the contaminant removing member bottom plate 17 is disposed under the light irradiating means 11. Is preferred (see FIG. 1).

The above-described bottom member 3 only needs to be strong enough to install one or a plurality of contaminant removing members 4 and a fixing portion 5 for fixing the contaminant removing member on the upper surface, and there is no influence even when a cleaning liquid such as rainwater is applied. Any material can be used. In addition, it is desirable to have a structure with only a skeleton, and by doing so, weight reduction can be achieved (FIG. 1).
Further, when the air purification duct type hollow structure 1 is arranged in an up-and-down direction and the pollutant removing member fixing device 7 is washed in a state where it is aligned vertically, it is advantageous in supplying water immediately below.

Furthermore, when the pollutant removing member 4 is made of a photocatalyst, it is important not to block the light irradiated from the light irradiation means 11 provided on the bottom member 3. Similar effects can be obtained by combining a skeleton and a plate-like light transmissive member.
The bottom member 3 is preferably provided with an anti-slip wall 10 (not shown) in order to prevent the fixed contaminant removing member 4 from being displaced.
Examples of the light transmissive member include quartz, borosilicate glass, and ultraviolet transmissive resin. When a visible light responsive photocatalyst is used, various types of glass and light transmissive resin can be used.

  The fixing part 15 for fixing the bottom plate 17 of the contaminant removing member is provided with an engaging part or a supporting part at a part of the bottom member 3 of the fixing device 7 so as to project the contaminant removing member bottom plate 17. Engage or support. It is preferable to provide an anti-slip wall (not shown) for preventing the fixed contaminant removing member bottom plate 17 from dropping or shifting at the end of the engaging portion or the supporting portion.

  When the bottom plate 17 is composed of a plurality of members and a bottom surface for supporting the bottom plate 17 is necessary, the fixing portion 15 is preferably provided with a transfer member or the like instead of the bottom surface covering the entire surface. Thereby, the contact portion between the bottom surface of the bottom plate 17 and the bottom surface of the fixing portion 15 can be reduced, and a wide contact area between the contaminated air and the contaminant removing member bottom plate 17 can be secured.

The light irradiation means 11 is desirably installed at a position where the contaminant removing member 4 made of a photocatalyst can be irradiated and the movement of the contaminant removing member fixing device 7 is not affected.
Examples of the light irradiation means include ultraviolet light irradiated black light, ultraviolet LED, ultraviolet lamp or a combination thereof. When the photocatalyst is a visible light responsive photocatalyst, a light source such as a fluorescent lamp or an LED can be installed instead of the ultraviolet irradiation means. A fluorescent lamp type black light is a unit in which a plurality of black lights are integrated by a socket part (see FIG. 1) and fixed to the light irradiation means fixing part 16 in accordance with the longitudinal direction or the short direction of the duct type hollow structure 2. It is.

When installing the light irradiation means 11 in the duct-type hollow structure 2, it is desirable to arrange the light irradiation means 11 so as to reduce the rate of hindering sunlight irradiation. For example, it is arranged in the same direction as the member immediately above the contaminant removing member 4. Further, when the pollutant removing members 4 are arranged in the hollow structure 2 at intervals in the longitudinal direction, the pollutant removing members 4 are arranged in the longitudinal direction or the transversal direction at the interval portion.
If the LED is used, the occupied area can be reduced, and the ratio of blocking sunlight is reduced. Therefore, the LED can be arbitrarily arranged in a place superior to light irradiation to the contaminant removing member.

  The light irradiating means fixing portion 16 can be easily removed from the light irradiating means 11 so that the influence of cleaning on the light irradiating means 11 can be eliminated. An engaging portion or a supporting portion is formed in a part to engage or support the light irradiation means 11. It is preferable to provide an anti-slip wall (not shown) for preventing the fixed light irradiation means 11 from dropping or shifting at the end of the engaging part or the support part.

The light irradiation means 11 is arranged, for example, at an interval so as not to block the irradiation of sunlight from the top plate 9 as much as possible, and the fixing portion 16 is not provided with a bottom surface.
Also, the wiring of the light irradiating means is integrated into one, fixed along the inner wall surface of the duct type hollow structure 2, and connected to the power distribution part in the middle of the duct type hollow structure 2 or from the entrance / exit. . When taking out from the middle of the said duct type hollow structure 2, packing is provided in order to prevent inundation into the duct type hollow structure.

When the pollutant removing member 4 is not a photocatalyst, it is not necessary to install the light irradiating means 11, so that the pollutant removing member bottom plate 17 is installed in the light irradiating means fixing portion 16 instead of the light irradiating means 11. Is also possible. By doing in this way, in addition to a pollutant removal member standing part, two pollutant removal member bottom plates can be arrange | positioned, and a cleaning function can be reinforced.
The contaminant removing member bottom plate fixing portion 15 and the light irradiation means fixing portion 16 are similar in structure, and the light irradiation means 11 is contaminated by the contaminant removal member bottom plate fixing portion 15 and the light irradiation means fixing portion 16 is contaminated. It is also possible to install a substance removal member bottom plate 17.

  Referring to FIG. 2, the other components of the contaminant removing member fixing device 7 will be described. As the movable support means 6 for supporting the bottom member 3, a caster 6 a, a roller conveyor 6 b, and a wheel conveyor are attached to the bottom member 3. It is possible to attach. Moreover, a guide rail or a slide rail may be provided on the inner surface of the hollow structure 2 to assist the straight running of the caster 6a. The caster 6a preferably has a stopper function 12.

In addition to the above configuration, a linear rail block may be attached to the bottom member 3, and the linear structure may be provided in the hollow structure 2 for running. It is also possible to provide an anti-slip wall (not shown) inside the hollow structure 2.
And when using the said air purification duct type | mold hollow structure 1 connected in series, since the anti-slip | skid wall should just be provided only in the head and the tail, it is preferable that the said anti-slip | skid wall is detachable.

  On the other hand, as the movable support means 6 of the fixing device 7b provided on the inner wall surface of the hollow structure 2, a roller conveyor 6b or a wheel conveyor (a soroban wheel conveyor, an accordion conveyor, a single staggered wheel conveyor, a single single row wheel conveyor, etc.) is used. It can be set as the structure which attaches to the said duct type | mold hollow structure 2, and slides the said bottom member 3. FIG. It is preferable to provide an anti-slip wall inside the hollow structure 2.

Furthermore, in the embodiment in which the movable support means 6 of the contaminant removing member fixing device 7 is attached to the duct type hollow structure 2 like a roller conveyor or a wheel conveyor, the bottom plate 17 of the contaminant removing member is also attached to the roller conveyor or the wheel conveyor. There is a possibility of contact. In order to avoid this, it is desirable to arrange the plate member 20 under the bottom plate fixing portion 15 and the light irradiation means fixing portion 16. Thereby, the action | operation of the movable support means 6 can be made easier, without damaging the baseplate 17 (FIG. 3). However, it is desirable to provide a gap in the plate member 20 in order to improve drainage during cleaning.
With the above configuration, when the pollutant removing member 4 is a photocatalyst, the light irradiation means 11 is used in combination under the condition where sunlight is irradiated, and the ultraviolet rays are reinforced near the bottom surface where the amount of received ultraviolet rays is lower. It is also possible to reinforce the ultraviolet light of the season when the ultraviolet light is weak. Under conditions where sunlight is not irradiated, such as at night, ultraviolet irradiation functions effectively.

  The auxiliary movable support means 24 that can be folded by the folding mechanism is folded under the bottom plate fixing part 15 and the light irradiation means fixing part 16 of the fixing device 7 and stored in the duct type hollow structure 2 or It is connected and fixed to the fixing device 7 and is folded and stored outside the bottom surface of the duct type hollow structure 2. After the fixing device 7 is pulled out from the duct type hollow structure 2, the fixing device 7 is connected to the duct. The mold can be supported outside the hollow structure 2.

  The auxiliary movable support means 24 is preferably installed in the vicinity of both ends of the fixing device 7. By doing so, the fixing device 7 can be partly drawn out of the duct type hollow structure 2 and cleaned, and the whole can be drawn out and cleaned.

The auxiliary movable support means 24 can also be provided with a general height adjustment mechanism 25, and can be provided with a caster 26 with a stopper function at the tip (see FIGS. 2 and 3).
With this configuration, even when the air cleaning duct type hollow structure 1 is installed away from the ground, the fixing device 7 can be pulled out from the end of the duct type hollow structure 2 and easily cleaned.
Further, when a plurality of duct-type hollow structures 1 are installed so as to overlap each other in the vertical direction, the respective fixing devices 7 are similarly pulled out and cleaned by adjusting the support height by the height adjusting mechanism 25. (See FIG. 10).
When a plurality of air purification duct type hollow structures 1 are connected in series and used, the auxiliary movable support means 24 uses support means that can be folded and stored inside the air purification duct type hollow structure 1. (See FIG. 2).

  The opening / closing part 27 of the hollow structure body 2 may be provided at any location as long as the contaminant removal member 4 and / or the contaminant removal member fixing device 7 can be taken in and out. It may be of any form, such as one that opens and closes the opening with a sliding door member, and one that opens and closes the opening with a lid member.

In order to improve the sealing performance of the door member or the lid member, it is preferable to install a packing in the opening. For example, when the upper part of the opening / closing part is pivotally attached to the side surface of the hollow structure main body 2 and provided so as to be opened from below, it can be used by connecting a plurality of air purification duct type hollow structures 1 in series, When it is necessary to clean the pollutant removing member 4 arranged in the air cleaning duct type hollow structure 1 that is not the head or tail, or when there is not enough space to continuously draw out a plurality of the members, the fixing from the opening / closing part 27 The device 7 can be pulled out to the side for cleaning (FIG. 11).
In addition, when the air-cleaning duct type hollow structures 1 are connected with a duct having a curved portion (when a plurality of duct type hollow structures 1 are connected to change directions or meander), The opening / closing part 27 can be pulled out and cleaned.

  On the other hand, when a plurality of air purifying duct type hollow structures 1 are connected in series and are also stacked in the vertical direction, they are arranged in a duct type hollow structure arranged at the second or higher stage rather than at the head and tail. When it becomes necessary to clean the pollutant removing member 4, the opening / closing part 27 is pulled out by providing a lower part of the opening / closing part pivotally attached to the side surface of the duct-type hollow structure so that the opening / closing part 27 can be pivotally opened from above. If it becomes a support floor surface of the pollutant removal member fixing device 7 and a table or the like is placed therebelow, it can be cleaned (FIG. 12). Thus, when pulling out the fixing device 7 from the opening / closing part 27 on the side surface of the air purification duct type hollow structure 1, the caster 6a can be moved by using the pollutant removing member fixing device 7a with casters. It can be pulled out in different directions.

The means for connecting the contaminant removing member fixing devices 7 may be any means as long as they can connect the fixing devices 7 adjacent to each other in the front-rear direction when a plurality of air purification duct type hollow structures 1 are connected in series. .
A specific example will be described with reference to FIG.
As an example, one or a plurality of holes 21a are drilled at both ends of the bottom member 3 of the adjacent fixing device 7, and the holes of the adjacent plate 21a and the dedicated plate material 22a provided with holes at the two ends are provided. Overlap and insert the stopper 23 and fix.
As another example, it is also possible to insert and fix a dedicated plate member 22b having protrusions at two locations in the holes 21b of the adjacent fixing devices 7.
Further, the adjacent fixing devices 7 may be fastened with a dedicated clip.
Whatever form is adopted, it is desirable that the connection can be easily formed and released. By adopting such a configuration, it is possible to pull out the fixing device 7 connected later by pulling out the leading fixing device 7 and to facilitate cleaning.

  When the performance of the pollutant removing member 4 is deteriorated due to adsorption of pollutants, etc., the pollutant removing member fixing device 7 is pulled out from the air cleaning duct type hollow structure 1 and water is sprayed by rain or a hose. By performing the cleaning, it is possible to easily perform cleaning without providing a cleaning device that requires maintenance for preventing clogging or replacement of a clogging prevention member such as a filter (FIGS. 6.10 to 12). In washing with a hose, tap water may be connected to a faucet, or rainwater, tap water, ion exchange water, distilled water, etc. stored in a storage tank may be supplied by an electric pump. Then, it can be dried by the sun or returned to the hollow structure after washing and dried naturally.

After the contaminant removing member fixing device 7 is completely or partially pulled out from the duct-type hollow structure, a member 13 that slides the inlet / outlet portion in order to prevent water from entering the hollow structure 1 is provided. It is desirable to make it easy to attach (FIG. 7). In addition, by changing the mounting method to the air supply / exhaust port, it becomes a hood member for preventing rainwater from entering due to rain when cleaning the air, and a lid for preventing water from entering the hollow structure 1 when cleaning the contaminant removing member. An opening / closing means 14 as a member can be provided (FIG. 8).
When the duct-type hollow structure having the air cleaning effect is inclined and installed, the height of the anti-slip wall and the fixing portion can be increased to prevent the displacement.
As described in detail above, the contaminant removing member fixing device of the present invention can be taken in and out of the duct-type hollow structure with the contaminant removing member fixed, so that the contaminant removing member can be cleaned and replaced. It is possible to provide an air purifying duct type hollow structure that can save labor, prevent a reduction in contaminant removal efficiency associated with the washing tube blocking sunlight and ultraviolet rays, and reduce running costs.
