Description

Recirculated hybrid system integrated with photo-catalytic reactor packed with reflecting film-photocatalytic catalyst cartridge

According to the present invention, although the pollutant load of volatile organic compounds or odor pollutants generated at industrial sites is largely varied according to the change of process conditions, the flow rate of process waste gas is also largely varied according to the change of process conditions. The present invention relates to a process and apparatus for a recycling hybrid system as shown in FIGS. 1 to 12 combined with a new photocatalytic reactor and a biofilter inducing a high-efficiency photocatalytic reaction by a vapor deposition, vacuum deposition, or plated reflective film on an outer diameter of the photocatalyst.

Volatile organic compounds and odors generated at existing industrial sites are mainly treated by adsorption, absorption or biological treatment. However, the adsorption and absorption methods require secondary treatment of adsorbents and absorbents, and biological treatments that preferentially decompose contaminants into stable substances such as water and carbon dioxide are preferred.

In industrial sites, there is a large variation in the pollutant load of volatile organic compounds or odor pollutants and the flow rate of waste gas generated according to changes in process conditions of the industrial site. Therefore, the concentration of volatile organic compounds or odor pollutants in the waste gas generated at industrial sites can also change frequently depending on the pollutant load and the waste gas flow rate.

On the other hand, biological treatment of waste gas containing volatile organic compounds or odor pollutants has advantages such as no need for secondary treatment as compared to adsorption and absorption methods as described above. However, when the concentration of pollutants toxic to the microorganisms present in the exhaust gas to be treated is above a certain concentration that negatively affects the growth or survival of the microorganisms, the microorganisms are deactivated and the use of microbial treatment methods such as biofilters is limited. . In addition, if the pollution load of volatile organic compounds or odor pollutants caused by the change of process conditions in the industrial site increases rapidly and exceeds the designed maximum elimination capacity of biological treatment facilities such as biofilters, It is not possible to meet the treatment concentration standards of the exhaust gas, so additional processes need to be installed before or after the biofilter process.

Patent Publication No. 10-2004-0073637 is a problem in that it is impossible to treat a biological treatment system in a high concentration range of volatile organic compounds. Therefore, when the concentration of the treatment source in exhaust gas is higher than the concentration of biological treatment, the above-described hybrid process is used. And when the concentration is low, a method and apparatus for selectively using a biological treatment and a photochemical treatment using only a biofilter have been disclosed. However, Patent Publication No. 10-2004-0073637 is a problem in that biological treatment systems cannot be processed at high concentration ranges of volatile organic compounds. Although the waste gas treatment method can be selected as a pretreatment process, the motivation and purpose of presenting the photochemical method and the synergy effect of the hybrid system consisting of the photocatalytic reactor and the biofilter are not mentioned. Similarly, Korean Patent Publication No. 10-2004- In the example and the comparative example of 0073637, only the performance results when operating only the biofilter and the biofilter and the photocatalytic reactor and the biofilter were compared with each other, and there was no patent claim for synergy characteristics of the hybrid process itself. Therefore, rather than claiming the hybrid system itself consisting of photocatalytic reactor and biofilter, it focuses only on the fact that biological treatment is impossible in the high concentration range of volatile organic compounds. Patents and methods of selectively using biological and photochemical treatments are claimed. However, biological treatment generally completely decomposes volatile organic compounds mainly into carbon dioxide and water, but when treating photochemically high concentrations of volatile organic compounds that cannot be biologically treated, untreated waste gases containing suspected carcinogens, depending on the process conditions It can produce many kinds of intermediate derivatives that are more harmful to the human body than the pollutant contained in the chemicals, which can cause more serious problems in all cases of photochemical treatment of high concentrations of volatile organic compounds that are not biologically processed in the industrial field. Can be. In addition, since photochemical treatment uses UV-B or UV-C having a short wavelength, which is harmful to the human body in general, access is limited and difficult to handle.

An object of the present invention is to measure the concentration and the load of pollutant generated in the industrial field and to measure the concentration of pollutant and the new UV / photocatalytic reactor (24, 25, 38 or 40) based on the pollutant load expressed as the product of the pollutant concentration and the flow rate, not the pollutant concentration. ) And the biofilter (13) process can be used at the same time, and the biofilter (13) process can be reasonably distinguished. In the case of the pollutant, by selectively reducing the use of the UV / photocatalytic reaction process (24, 25, 38 or 40) by selectively using a recirculation system that dilutes the process waste gas (1) introduced by recycling the treated waste gas (12). Carcinogenic susceptible substances produced according to process conditions when photochemically treating high concentrations of volatile organic compounds that cannot be biologically treated To minimize the serious problems such as many kinds of intermediate derivatives that are more harmful to the human body than the pollutant to be treated, and to provide a method and apparatus for treating the waste gas including pollutant generated in the industrial site regardless of the concentration of the pollutant, Even when the UV / photocatalytic reactor (24, 25, 38 or 40) and the biofilter 13 process must be used simultaneously based on the contamination load, the treated waste gas 12 of the proper transport rate is recycled and coated with a photocatalyst including TiO ₂ . Or a cyclic or tubular honeycomb cartridge (37 or 39) coated on the surface with a photocatalyst comprising a transparent or translucent filler (6) having an adsorptive capacity dispersed and supported by photocatalytic nanoparticles and titanium dioxide. Synergy of hybrid system consisting of photocatalytic process and biofilter by charging photocatalytic reactor (24, 25, 38 or 40) Maximize the effect to minimize the design scale of the biofilter 13 or UV / photocatalytic reactor (24, 25, 38 or 40) to reduce the investment and operating costs. In addition, the outer diameter (7 or 34) of the new photocatalytic reactor 24 is 1) in the case of the transparent support 27, such as quartz, glass or silica, as shown in Figure 3, the inner surface in contact with the waste gas is a photocatalyst sol such as titanium dioxide After dip coating, the photocatalyst coating 26 was calcined at about 450 ° C., and the outer surface was coated with a reflective film 28 by vacuum evaporation, vapor deposition, or plating of a metal such as aluminum or silver. In the case of the opaque support 32, such as an opaque metal or plastic, a photocatalyst coating 26 is formed on the reflective film 28 by vacuum evaporation, vapor deposition, or plating of a metal such as aluminum or silver thereon to contact the waste gas thereon. In addition, a circular double tube is fabricated between the inner diameter (8) and the outer diameter (7 or 34) by a photocatalyst containing TiO ₂ or a transparent or translucent filler (6) having adsorptive capacity dispersed and supported by photocatalytic nanoparticles. And the UV lamp 5 is inserted inside the inner diameter 8 to absorb / pass the ultraviolet rays between the transparent or translucent fillers 6 to reach the photocatalytic coating 26 of the outer diameter 7 or 34 and absorb / After passing through, it is reflected by the reflecting film 28 to be reabsorbed / repassed between the photocatalytic coating 26 and the transparent filler 6 of the outer diameter 7 or 34 to transmit light or light by the support of the photocatalytic reactor outer diameter 7 or 34. Minimize absorption loss to maximize efficiency of light source and induce high efficiency photocatalytic reaction by photocatalyst for volatile organic compounds or odorous components in waste gas. This applies equally to new photocatalytic reactors 25, 38 or 40.

The technical method of the present invention is described as the following reasonable divisions.

1) when the pollutant load is less than the designed maximum elimination capacity of the biofilter by measuring the waste gas flow rate to be treated and the concentration of pollutant in the waste gas in real time;

 A) If the concentration of pollutant in the waste gas is not high for biological treatment, the treated waste gas 12 is recycled to be treated with a biofilter by selectively using a recycling system for diluting the incoming process waste gas 1 to a concentration capable of biological treatment. and

B) If the concentration of pollutant in waste gas is lower than that, treat it with biofilter without dilution.

2) If the pollutant load exceeds the designed maximum elimination capacity of the biofilter by measuring the waste gas flow rate and the pollutant concentration in the waste gas in real time, the incoming waste gas is passed through the UV / photocatalytic reactor to remain in the treated waste gas. UV / photocatalytic reactors (24, 25, 38 or 40) and biofilters (13) so that the pollutant load is less than the combined total removal capacity of the hybrid system's synergy and the designed maximum elimination capacity of the biofilter. The optimum transport ratio for recycling the waste gas (12) treated by the reactor is designed and the photocatalyst treated waste gas is supplied to the biofilter.

In the present invention, first, the concentration of the pollutant and the pollutant load generated at an industrial site are measured, and the UV / photocatalytic reactor and the biofilter process are simultaneously used based on the pollutant load expressed as the product of the pollutant concentration and the flow rate, not the pollutant concentration. Cases that could only be achieved by the biofilter process were reasonably classified. Therefore, by using UV / photocatalytic process as much as possible, it is possible to generate high concentrations of volatile organic compounds contained in process waste gas by UV / photocatalytic process. Serious problems such as many kinds of intermediate derivatives harmful to the human body, including suspected carcinogens, can be minimized. Second, if the pollutant concentration in the process waste gas (1) is too high for biological treatment but the contamination load is less than the designed maximum elimination capacity of the biofilter, the treated waste gas (12) is titrated instead of using the UV / photocatalytic reaction process. The pollutant concentration of the process waste gas 1 introduced by recycling to the return ratio may be diluted to be lowered to the pollutant concentration that can be treated by the biofilter 13 and then treated only by the biofilter 13. Third, the waste gas 12 treated in the hybrid system consisting of the photocatalytic reactor 24, 25, 38 or 40 and the biofilter 13 is recycled to the photocatalytic reactor 24, 25, 38 or 40 at an appropriate transport rate, thereby allowing the sugar system to be recycled. Recyclable hybrid process system that maximizes the synergy effect of the system, minimizing the design scale of the biofilter or UV / photocatalytic reactor to reduce the investment cost and operation cost. Fourth, as a hybrid system of the photocatalytic reactor 24, 25, 38, or 40 and the biofilter 13, filled with a photocatalyst comprising TiO _{2 and} filled as an adsorbent filler 6 dispersed or supported by photocatalytic nanoparticles. Increasing the removal efficiency of volatile organic compounds and odor pollutants in the photocatalytic reactor (24, 25, 38 or 40) by the adsorption capacity of 6) enhances the synergy effect of the hybrid system. Fifth, when the flow rate of the process waste gas 1 generated in the industrial site is relatively small, as shown in Fig. 1, the inner diameter 8 of the annular new photocatalytic reactor 24 or 38 is made of a transparent tube equivalent to quartz or glass, and the outer diameter is In the case of the transparent support 27 such as quartz, glass or silica, the inner surface of the support in contact with the waste gas is dip coated with a photocatalyst sol such as titanium dioxide. Later, the photocatalyst coating 26 was calcined at about 450 ° C., and the outer surface of the support was coated with a reflective film 28 by vacuum evaporation, vapor deposition, or plating of a metal such as aluminum or silver, respectively. In the case of the opaque support 32, such as an opaque metal or a plastic, a reflective film 28 is coated on the opaque support 32 by vacuum depositing, depositing or plating a metal such as aluminum or silver, respectively, and contacting the waste gas thereon.

Absorbed / passed to (37) to reach the photocatalytic coating 26 of outer diameter (7 or 34), and after absorption / passage, is reflected off the reflecting film (28) to allow photocatalyst coating (26) and filler (6) to outer diameter (7 or 34). Or recirculated into the annular honeycomb cartridge 37 to induce a high efficiency photolysis reaction by a photocatalyst for volatile organic compounds or odorous components contained in the waste gas. Sixth, when the flow rate of the process waste gas (1) generated in the industrial site is relatively large, as shown in FIG. 2, the new tubular photocatalytic reactor (25 or 40) is discharged to the blower (2) at the industrial site.

Filled transparent tubes 36 equivalent to the blocked quartz or glass into which the UV lamp 5 is to be inserted at regular intervals in the longitudinal direction of the finished tube (6) and the tubular honeycomb cartridge (39) arranged in the vertical or oblique direction of the length of the tube, and a plurality of ultraviolet lamps (5) are inserted into a transparent tube (36) equivalent to each quartz or glass placed and transparent tube ( The photocatalyst was also coated on the outside to improve the photocatalytic reaction. The outer diameter 20 or 35 of the new tubular photocatalytic reactor 25 or 40 is 1) in the case of a tubular support 30 which is transparent, such as quartz, glass or silica, as shown in Fig. 4 or Fig. After dip coating a photocatalyst sol such as titanium dioxide, it is calcined at about 450 ° C. to form a tubular photocatalyst coating 29.

Plating is applied to the tubular reflective film 31 and coated on the tubular photocatalyst 29 in contact with the waste gas, so that ultraviolet light is absorbed / passed through the filler 6 or the tubular honeycomb cartridge 39 to the outer diameter 20 or 35. of After reaching and absorbing / passing the tubular photocatalyst coating 29, it is reflected by the tubular reflecting film 31 and reabsorbed by the tubular photocatalyst coating 29 and filler 6 or tubular honeycomb cartridge 39 of outer diameter 20 or 35. It is effective to induce high efficiency photolysis reaction by photocatalyst for volatile organic compounds or odorous components contained in the waste gas.

The configuration of the present invention is the introduction of the gas flow meter (3) and the electrochemical real-time concentration analyzer (4) capable of calculating the pollutant load of volatile organic compounds and odor pollutants as shown in Figs.

The process is performed by the biofilter 13 without making it work. On the other hand, the waste gas flow rate to be treated and the concentration of pollutant in the waste gas are measured in real time with a gas flow meter (3) and an electrochemical real-time concentration meter (4) so that when the pollution load is more than the designed maximum elimination capacity of the biofilter, The waste gas is passed through a new photocatalytic reactor (24, 25, 38 or 40). The residual pollutant concentration of the waste gas treated with the new photocatalytic reactor (24, 25, 38, or 40) was measured by the electrochemical real-time concentration meter (9), so that the remaining pollutant load was measured with the new photocatalytic reactor (24, 25, 38, or 40). New photocatalytic reactors 24, 25, 38, or 40 may be used so that the synergy effect of the hybrid system consisting of the biofilter 13 and the combined total removal capacity of the designed maximum elimination capacity of the biofilter 13 is less than or equal to the sum total. The designed and supplied photocatalyst waste gas is supplied to the biofilter 13 through the humidifier 23, and the method is performed when the above-mentioned pollution load is equal to or less than the designed maximum elimination capacity of the biofilter 13; same.

The new photocatalytic reactor 24, 25, 38 or 40 is the first internal diameter of the annular new photocatalytic reactor 24 or 38 when the flow rate of the process waste gas 1 generated in the industrial site is relatively small as shown in FIG. 8) is made of a transparent tube equivalent to quartz or glass, and the outer diameter (7 or 34) is 1) the inner surface of the support in contact with the waste gas in the case of a transparent support 27 such as quartz, glass or silica as shown in Fig. 3 or 7 After dip coating a photocatalyst sol such as silver titanium dioxide, the photocatalyst is coated by calcining at about 450 ° C.

In addition, the photodegradation was improved by coating a photocatalyst on the outside of the inner diameter 8 in which the process waste gas contacts.

Second, when the flow rate of the process waste gas (1) generated in the industrial site is relatively large, as shown in Figure 2, the new tubular photocatalytic reactor (25 or 40) is discharged to the blower (2) in the industrial site Perforated partition 21 inside the process waste gas delivery pipe 22 made of glass, plastic or metal tubes of corrosion-resistant round or square or other form that connects the atmosphere or waste gas containing compounds or odors to the humidification tank 23. ) And a tubular honeycomb cartridge 39 coated with a photocatalyst containing TiO ₂ or dispersed and supported by photocatalytic nanoparticles and a tubular honeycomb cartridge 39 coated with a photocatalyst including titanium dioxide at an appropriate ratio.

Waste gas introduced through the humidifier 23 to the upper portion of the biofilter 13 passes between the microbial carriers 17 filled in the biofilter, and the volatile organic compound or odor generating source included in the biofilter inlet gas is microorganisms. It is removed through absorption and biodegradation by the membrane, and the waste gas 12 treated with the biofilter or hybrid system is discharged to the atmosphere. In order to maximize the efficiency of hybrid systems that combine UV / photocatalytic reactors and biofilters filled with photocatalyst carriers, it is necessary to recycle synergistic effects of hybrid systems by recycling untreated sources to UV / photocatalytic reactors. It is possible to expect a reduction in the treatment efficiency per volume of the reactor due to the back-mixing effect generated when a part of the treated waste gas is recycled. Therefore, there is an optimal transport ratio of the hybrid system, by maximizing the synergy effect of the hybrid system consisting of the photocatalytic reactor 24, 25, 38 or 40 and the biofilter 13 by recycling the treatment waste gas 12 of the appropriate transport ratio.
