Prefabricated performance test device for filter-type photocatalyst sample}

The present invention is a device for evaluating the performance of a filter-type photocatalyst sample, and is a prefabricated performance evaluation device for a filter-type photocatalyst sample in which a holder module having a sample holder and a reaction space is disposed inside a reaction tank to facilitate filter replacement and maintenance. it's about

Catalyst is a substance that directly participates in a reaction and is not consumed and affects only the reaction rate. Among them, photocatalyst refers to a catalyst that accelerates the reaction rate by providing a different mechanism path to the existing photoreaction when light is applied.

Most of the contaminant decomposition reaction on the photocatalyst is due to the strong oxidizing power of hydroxyl radicals generated on the surface, but the overall mechanism is a series of events involving not only hydroxyl radicals, but also holes in shared bands, electrons in conduction bands, and superoxide anions (active oxygen species). In this process, various contaminants such as organic substances, odorous substances, viruses, and bacteria in the air or water are decomposed into water and carbon dioxide.

In general, standardized methods for evaluating the air purifying performance of photocatalysts include the ISO 22197 series (ultraviolet light) or the ISO 17168 series (indoor light). In the above test method, the performance of the photocatalyst material is evaluated by determining the degree of reduction through the oxidation/reduction reaction of the contaminant by the photocatalyst material when a contaminant of a certain concentration is continuously flowed on the surface of the sample.

For photocatalyst performance evaluation, a sample should be injected into a photocatalyst reactor of a prescribed size (5 cm x 10 cm x 5 mm). Existing experimental evaluation devices are regulated to directly put a sample inside, but there is no separate regulation for a sample holder manufactured in a filter type. In particular, in the case of a filter-type sample, since the evaluation device must be configured in such a way that the contaminant gas passes through the filter rather than simply contacting the surface of the photocatalyst material with contaminant gas, it has a more complicated configuration than a flat-type sample.

Since the existing performance evaluation device has a sample holder attached to the upper reaction tank, the design of the evaluation device is complicated, the sample mounting process is complicated, and a lot of labor is required. In particular, this structure has a disadvantage in that it is impossible to evaluate a low-efficiency filter-type sample that must be arranged so that pollutant gas continuously passes through two filter-type samples due to low performance.

For the above reasons, a replaceable sample holder is provided so that the filter-type photocatalyst sample can be more conveniently installed or removed in the reaction device, so that multiple samples can be evaluated simultaneously, cleaning is easy, manufacturing cost is minimized, and component damage There is an increasing need for a performance evaluation device for a filter-type photocatalyst sample configured to more easily perform replacement.

1 is a cross-sectional view showing a state in which a plurality of holder modules 400 according to the present invention are mounted. Referring to this,

The filter-type sample 100 is molded of a filter-type photocatalyst configured to filter air by mixing a photocatalyst, and a test piece is generally manufactured in a rectangular shape with a height of 99.0 mm and a width of 49.0 mm. Therefore, the holder module 400 provided by the present invention is preferably formed in a size that can accommodate the filter-type sample 100 formed in the above size in close contact.

The reaction tank 200 has an accommodating space 210 inserted downwardly from the upper surface, and the accommodating space 210 in which the holder module 400 is accommodated may be formed in various shapes of polyhedrons. Accordingly, the accommodation space 210 is formed surrounded by the bottom plate and the circumferential surface of the reaction tank 200, and since the upper side is open, the holder module 400 can be inserted from the upper side.

The shape of the bottom plate and the circumferential surface can be configured in various ways, but in the embodiment shown in the drawings of the present invention, the accommodation space 210 is formed in a rectangular parallelepiped and the holder module 400 also corresponds to the accommodation space 210. It is formed as a rectangular parallelepiped.

The reaction tank 200 may be made of a metal material (aluminum, stainless steel, etc.) or a plastic material (acrylic resin, etc.) that does not adsorb the injected pollutant gas or react with the pollutant gas. This is to remove factors that may affect the concentration of the gas injected into the reaction tank 200 other than the photocatalyst filter type sample 100 to be evaluated as much as possible.

The accommodating space 210 is a space in which the holder module 400, which will be described later, is accommodated, and is formed in a form in which the outer portion of the holder module 400 can be placed in close contact with the peripheral portion of the accommodating space 210. can In particular, as described above, the accommodating space 210 is preferably composed of a hexahedron formed to have a quadrangular plane.

The floodlight plate 300 is configured to cover the receiving space 210 of the reaction tank 200, and the floodlight plate 300 is necessary for evaluating photocatalytic performance when light is irradiated, and quartz glass, borosilicate glass It is desirable to make a material capable of minimizing energy absorption in the process of transmitting light. Therefore, an experimental lighting device that projects light with a constant luminous intensity at a certain distance from the top of the floodlight panel 300 should be provided.

The holder module 400 is disposed in the receiving space 210 of the reaction tank 200 and is configured to accommodate the filter-type sample 100 . The holder module 400 may be made of a plastic material that does not adsorb or react with the injected pollutant gas.

A typical sample holder serves only as a receptor for accommodating a photocatalyst, but the holder module 400 provided by the present invention not only fixes the filter-type sample 100, but also has a gas inlet and outlet 450 and the reaction space 430 are integrally formed so that complicated experimental procedures and processes can be skipped and rapid experiment preparation can be performed.

In order to perform the above functions, the sample holder of the present invention is constructed in a modular type, and the structure of the holder module 400 provided by the present invention will be described in detail below.

The holder module 400 may be formed as a hexahedron having a quadrangular plane.

In the embodiment shown in the drawing of the present invention, the accommodating space 210 is formed in a rectangular parallelepiped, and the holder module 400 corresponds to the shape of the accommodating space 210 so that it can be accommodated in close contact with the accommodating space 210. It is formed as a cuboid. Therefore, when the single holder module 400 is accommodated in the accommodating space 210, the accommodating space 210 is formed to correspond to the shape and size of the single holder module 400, and the plurality of holder modules 400 When combined in series and accommodated in the accommodating space 210, the accommodating space 210 may be formed to correspond to the shape and size of the plurality of holder modules 400. The reaction tank 200 may be formed in a shape and size to accommodate the accommodating space 210 .

Also, the holder module 400 may be formed to have the same height as the accommodation space 210 . When the floodlight plate 300 is coupled to the upper surface of the reaction tank 200, it may cover the accommodation space 210 and be closely adhered to the upper surface of the holder module 400.

The injection passage 410 is formed on the lower part of the front surface of the holder module 400 and configured to introduce gas.

In addition, the injection passage 410 may be configured such that gas introduced through the injection hole 500 or the discharge passage 450 of the other holder module 400 moves to the vertical slit 420 .

Referring to the embodiment of FIG. 1, [FIG. 1] shows a state in which the front holder module 400 and the rear holder module 400 are disposed adjacent to each other in the accommodation space 210 of the reaction tank 200. there is.

At this time, it is confirmed that the injection passage 410 of the front holder module 400 communicates with the injection hole 500 and the injection passage 410 of the rear holder module 400 communicates with the discharge passage 450. can

As described above, the communication configuration of the injection path 410 may vary depending on the number and location of the holder modules 400 disposed in the receiving space 210 of the reaction tank 200 .

The cross section of the injection passage 410 may be formed in various shapes such as a square or a circle. In particular, in order to facilitate gas diffusion, the cross section of the injection path 410 is preferably formed in a rectangular cross section. In addition, in order to diffuse the gas in a direction, the cross section of the injection passage 410 may be configured to be widened from the front to the rear.

The vertical slit 420 may be formed in a slit-like shape elongated in a vertical direction. The vertical slit 420 has a rectangular cross section with a thin thickness so that the gas moved from the injection passage 410 spreads evenly over the thin rectangular cross section as it moves upward. The injection passage 410 and Since the vertical slits 420 are disposed orthogonally to each other, the gas discharged from the injection path 410 collides with the inner surface of the vertical slits 420 and then moves upward, thereby making it easier to disperse the gas. there is.

In more detail, the lower part of the vertical slit 420 communicates with the injection passage 410, and the upper part has a discharge port 421, so that the gas injected from the injection passage 410 communicating with the lower part passes through the vertical slit 420. ) can be widely dispersed along the inner cross-section in the process of moving upward.

The gas compressed and injected from the inlet 500 is dispersed and introduced along the cross-sectional shape of the injection passage 410, collides with the inner surface of the vertical slit 420 and is dispersed, and moves upward to form a slit. can be uniformly distributed over the cross section of In particular, when the cross section of the injection path 410 is configured to expand from the front to the rear direction, the gas diffuses in a direction and the dispersion effect is increased. Accordingly, the gas injected from the inlet 500 having a tubular cross-section passes through the injection passage 410 and the vertical slit 420 while moving along a narrow rectangular cross-section and uniformly entering the reaction space 430. can be widely spread. Therefore, the contaminant gas discharged from the discharge port 421 of the vertical slot 420 along the rectangular cross-section is uniformly dispersed and contacted with the filter-type sample 100 formed in the shape of a rectangular flat plate on the top surface, thereby providing more accurate results. experiments are possible.

The discharge port 421 may be formed in a continuous cross-sectional shape of the vertical slit 420 and communicate with the reaction space 430 .

The reaction space 430 communicates with the outlet 421 of the vertical slit 420 and is formed by being inserted from the upper surface of the holder module 400, and the light irradiated through the floodlight 300 transmits the filter-type sample (100) It is a space where a photocatalytic reaction occurs by reacting with the photocatalyst on the surface. When the floodlight panel 300 is combined with the reaction tank 200, the reaction space 430 is surrounded by the floodlight panel 300, the filter type sample 100, and the circumference of the reaction space 430. can be formed

In particular, in the photocatalyst, a photocatalytic reaction occurs only in a portion exposed to light, and a photocatalytic reaction does not occur in a portion not exposed to light. Therefore, when gas is injected into the top surface of the filter-type sample 100 that is exposed to light, the air purifying performance can be most accurately measured. Therefore, the reaction space 430 is formed as a narrow space in the range of 4.0 mm to 8.0 mm in height so that the injected gas flows in close contact with the upper surface of the filter-type sample 100 as much as possible. it is desirable to be

The inner space 440 may be formed to penetrate and communicate with the reaction space 430 downward. The circumference of the inner space 440 may be formed narrower than the circumference of the reaction space 430 so that the filter-type sample 100 is placed on the upper end of the circumference of the inner space 440 .

As shown in [FIG. 1], the reaction space 430 and the inner space 440 are formed to communicate in the vertical direction, and the filter-type sample 100 is formed between the reaction space 430 and the inner space ( 440) can be mounted horizontally on the perimeter. At this time, since the circumference of the filter-type sample 100 is placed in close contact with the circumference of the reaction space 430, the injected gas flows from the reaction space 430 to the inner space 440 without leaking into the filter-type sample. (100) will pass.

In more detail, the gas injected through the discharge port 421 of the vertical slit 420 is evenly spread and dispersed in the rectangular flat filter-type sample 100, reacts with the photocatalyst on the upper surface of the filter-type sample 100, It passes through the filter type sample 100 and flows into the inner space 440 .

Therefore, since the holder module 400 provided by the present invention is configured such that the injected gas passes from the top to the bottom of the filter-type sample 100, the photocatalytic reaction occurs only on the surface exposed to light, and thus the photocatalytic reaction It has the advantage of being able to measure accurately.

The discharge path 450 is formed at a lower portion opposite to the injection path 410 and communicates with the inner space 440 to discharge gas. Since the discharge passage 450 can communicate with the injection passage 410 of the other holder module 400, it is preferable to be formed in a form corresponding to the injection passage 410.

Therefore, the gas introduced into the reaction space 430 passes through the filter-type sample 100 and the contaminants are purified through a photocatalytic reaction, and the purified gas passes through the inner space 440 to the discharge path ( 450) can be discharged.

It may be configured to further include a rubber packing 460 provided along the circumference of the upper surface of the holder module 400 .

The rubber packing 460 is provided along the circumference of the upper surface of the holder module 400 to prevent damage to members caused by repeated contact/disassembly with the floodlight panel 300, and the holder module 400 and the The integrity of the floodlight panel 300 may be strengthened, and leakage of gas through a joint between both members may be prevented.

In the drawing of the present invention, an embodiment in which the rubber packing 460 is provided on the circumference of the upper surface of the holder module 400 is shown. In particular, as shown in [Figs. 2] to [5], a packing groove 461 into which the rubber packing 460 can be inserted may be formed along the circumference of the upper surface.

In addition, as shown in [FIG. 6B], it may be configured to further include a packing sheet 470 disposed to cover the top of the reaction tank 200.

The packing sheet 470 is formed of a light-transmitting soft material through which light is transmitted, and minimizes gas leakage by filling the gap formed between the light-transmitting plate 300, the upper surface of the reaction tank 200, and the upper surface of the holder module 400. can do. At this time, the packing sheet 470 is preferably formed of a material that does not absorb or react with the injected pollutant gas in order to derive accurate test data. In addition, the packing sheet 470 is formed of a light-transmitting soft synthetic resin so that light passing through the light-transmitting plate 300 can reach the filter-type sample 100 mounted on the holder module 400.
