Description

Composite deodorizer using micro nano vertex bubble and its control system {COMPOSITE DEODORIZATION APPARATUS USING MICRO NANO VERTEX BUBBLE AND CONTROL SYSTEM THEREOF}

The present invention relates to a complex deodorizer using micronanovertex bubbles and its control system.

More specifically, the present invention enables efficient odor removal operation by controlling the deodorizing fan driving speed according to the odor concentration and the air supply device driving speed that supplies air to the micro-nanovertex bubble generator.

There are various types of conventional deodorizers, but among them, tower-type deodorizers are widely applied in industrial sites.

The tower-type deodorizer stores water mixed with deodorizing chemicals (NaHCl2, etc.) or microorganisms that destroy odorous substances at the bottom of the tower tank, and is spaced vertically at a certain distance from the water surface in the tower tank to remove plastic material. A layer of particles is provided in the tower tank, a gas outlet is provided at the top of the tower tank, the gas to be deodorized is supplied between the layer of particles and the water surface, and the chemical or microorganism is contained on the layer of particles. By spraying water, the odorous components (H2S, NH3, CH3SH, etc.) of the gas to be deodorized flowing into the tank are captured and naturally fall to the bottom of the tank, and then added to the water containing the chemicals or microorganisms stored at the bottom of the tank. It acts to destroy various odorous substances dissolved in the water.

Another type of tower-type deodorizer has almost the same structure as the above deodorizer, but instead of using chemicals or microorganisms as a means of deodorizing, it uses ozone, which has strong oxidizing power. In this case, in order to remove these odorous substances well, it is necessary to use as much as possible. If so, it is necessary to dissolve a large amount of ozone in water.

The smaller the bubble containing high-concentration ozone, the more efficiently ozone dissolves in water. This is because the smaller the bubble, the greater the ratio of surface area to volume, so the ozone in the bubble has a greater chance of coming into contact with water.

Additionally, the reason for creating microbubbles is that the smaller the bubble size, the longer the bubble stays in the water. This is due to the viscosity of water, and if bubbles get close to nano-sized, they can exist almost permanently in water. In this case, almost all of the ozone in the microbubbles is dissolved in water, making it possible to create high-concentration ozone water, and as a result, odorous substances dissolved in water can be better removed.

Republic of Korea Patent Registration No. 10-1615515 is the applicant's registered patent, and the complex odor treatment system using catalytic oxidation water is a single cleaning solution using catalytic oxidation water containing radicals that react with all acidic odor components, basic odor components, and neutral odor components. It has a simple structure and is easy to manufacture, and it can fundamentally block the generation of neutral flames that inevitably occurred due to the collision between acid and alkaline cleaning fluids, thereby preventing a decrease in odor treatment efficiency due to the generation of neutral flames. And, due to the use of a single cleaning solution, complex odors can be quickly removed due to the rapid reaction of radicals within a given contact time between gas and liquid, and it is installed to prevent the two cleaning solutions from being neutralized in the existing deodorizing tower. It has a simple structure that lacks structural devices that prevent physical mixing, such as two demisters, two chemical pumps for transporting each chemical, and each independent cleaning fluid reservoir, and a single cleaning solution produces a complex odor. It can perform its original function for removal.

In addition, a two-fluid nozzle is installed in the exhaust gas duct or stack of an already installed deodorization facility, and the catalytic oxidation water is mixed with compressed air and sprayed in an aerosol state through the two-fluid nozzle, so that the untreated residual complex odor comes into contact with the catalytic oxidation water. It can be removed by further oxidation and decomposition, and by replacing the entire cleaning liquid in the single or continuous cleaning and deodorizing tower of a general system with catalytic oxidation water, the treatment efficiency can be improved by about 12% compared to the two-liquid simultaneous cleaning and deodorizing tower. , due to limitations in treatment efficiency of the tower, untreated complex odors and treatment efficiency varies depending on changes in the state of microorganisms, etc., to untreated odors from existing biofilm towers, the connection duct or final discharge stack of the existing odor treatment system By connecting a reactor in series, catalytic oxidation water containing OH radicals that can chemically react with all of the basic, acidic, and neutral odor components among the complex odor components is sprayed in the form of mist using a two-fluid nozzle to spray the untreated odor components. More than 50% of the odor can be additionally treated.

In addition, due to the limitations of the treatment efficiency (approximately 85%) of existing deodorization towers in existing single-cleaning deodorization towers, double-cleaning deodorization towers, two-liquid simultaneous cleaning deodorization towers, or bioprocessing systems, untreated waste is discharged into the atmosphere. Businesses that need to deal with approximately 15% of residual odor, or businesses that need to supplement existing odor facilities due to strengthened legal regulations that are different from those at the time of installation, or supplementary facilities that can handle odors generated from expanded production processes. It can be used in workplaces that are concerned about land issues due to a lack of installation site, or in workplaces where residual odor cannot be treated and discharged due to the inability to install separate supplementary equipment for other reasons, and can be used at the rear end of the inlet blower of an existing deodorization tower, or in multiple stages. Catalytic oxidation water is sprayed in the form of mist through a nozzle from the deodorization tower's connection duct or the deodorization tower's final discharge stack, and the untreated odor components discharged upward are combined with acidic, basic, and neutral odors through contact with gas and liquid. More than 98% can be removed by chemically reacting with radicals such as oxygen radicals and hydroxyl radicals, which can significantly improve the installation cost of a new or existing deodorization tower and the collection efficiency of complex odor gases.

Vortex grooves are further formed in communication with the operating space so that they flow in while moving and are vortexed and then discharged, and the vortex groove has a curved bubble guide surface to prevent the micro-nano bubble oxidized water from getting caught when discharged from the vortex groove after vortexing. A vibrator, which is a vibrator, is further screwed to the outer surface of the housing body, and one end of the vibrating pins is further welded to the stirring blades formed on the upper and lower surfaces of the impeller, so that the vibration transmitted from the vibrator is transmitted to the vibrating pin. It is configured to transmit water and chemicals. An impeller is installed to rotate in the housing body, and a vortex groove is formed inside the housing body, so that the water, air, and chemicals (oxidizing agent) that are injected and rotated into the housing body are in the vortex groove. The process of insertion and withdrawal is repeated to increase the formation efficiency of micro-nano bubble oxidized water.

Republic of Korea Patent Registration No. 10-2150864 relates to a deodorization system using nanobubbles, which includes a first reservoir provided to collect a certain amount of water inside, a first demister to remove moisture contained in the process gas, and , a first scrubber including one or more first venturi injectors that mix odor gas, ozone, and water and spray them into the air in the form of nanobubbles; A second reservoir provided to collect a certain amount of water inside, a second demister to remove moisture contained in the treated gas, and the water and treated gas supplied from the first scrubber are mixed with ozone to form nanobubbles. a second scrubber including one or more second venturi injectors that inject water stored in the second reservoir into the interior; A first pumping unit that pumps the water stored in the second scrubber together with ozone to the first venturi injector; and a second pumping unit that pumps the water stored in the first scrubber together with ozone to the second venturi injector, wherein nanobubbles are injected into the air from the first venturi injector and into the water from the second venturi injector. Effective removal of odor is possible through the adsorption and decomposition of odor-generating substances by nanobubbles.

However, in conventional deodorizers, the flow of catalytic oxidation water is static, so the reaction rate with malodorous organic substances introduced into the deodorizer is somewhat limited.

Therefore, considering that 70% of the deodorization system undergoes a primary reaction in water, and that unreacted odorous substances are secondary to decomposition of odorous organic substances by the Nozzle Atomization system within the scrubber, the primary reaction improves performance by more than 70%. It can be seen that it is effective in purifying the entire odor.

As shown in Figures 1 and 2, the composite deodorizer using micronanovertex bubbles according to the first embodiment of the present invention supplies air to the micronanovertex bubble generator 300 to generate micronanovertex bubbles. It consists of an air supply device (1) that generates micronanovertex bubbles using the air supplied from the air supply device (1) and a micronanovertex bubble generator (300).

The micronanovertex bubble generator 300 is configured in the catalytic oxidation water reservoir 200, and generates micronanovertex bubbles by mixing the air supplied from the air supply device 1 and catalytic oxidation water, and then generates micronanovertex bubbles in the catalytic oxidation water reservoir (200). 200) to ensure that the material is evenly stirred by micronanovertex bubbles.

In other words, the process of mixing the sludge mixed with air and catalytic oxidation water and breaking it into small pieces is repeated, thereby making the overall distribution of substances within the catalytic oxidation water storage tank 200 uniform.

The micronanovertex bubble generator 300 may be configured as shown in FIG. 3. However, it is not necessarily limited to this configuration.

As shown in FIG. 3, the micro-nanovertex bubble generator 300 has an outlet 301 for discharging air supplied from the air supply device 1 to the catalytic oxidation water storage tank 200, and a catalytic oxidation water storage tank 200. By mixing the sludge inlet 302 through which sludge mixed with catalytic oxidation water and air flows, the air passing through the air discharge port 301, and the sludge water passing through the sludge inlet 302, a strong The primary mixing unit 303 is composed of two plates crossing each other to generate a spiral flow, and the mixed material of air and sludge that has passed through the primary mixing unit 303 is broken into micro particle groups to remove oxygen.

The liquid is separated and broken into micro-particle groups in a short period of time, and the micro-particle groups continuously and strongly collide with each other due to centrifugal and centripetal forces.

In the composite deodorizer using micronanovertex bubbles according to the present invention, as shown in FIG. 4, when polluted external air containing odor components flows into the odor reaction tank 30 through the deodorization fan 10, the odor reaction tank ( 30) removes odor while the liquid catalyst flowing from the catalytic oxidation water storage tank 200 through the catalyst storage tank 50 is sprayed through the catalyst injection nozzle 40. The odor produced in the odor reaction tank 30 A micronanovertex bubble generator 300 that improves odor deodorization efficiency by using micronanovertex bubbles in the deodorization process is configured in the catalytic oxidation water storage tank 200.

Numeral 90 is a circulation pump that operates intermittently to control the circulation of catalytic oxidation water to the odor reaction tank 30, 60 is a sodium hypochlorite aqueous solution reaction tank, 70 is a chemical storage tank, and 80 is a water storage tank.

The odor reaction tank 30 is designed to desulfurize polluted external air by contacting it with a liquid catalyst. It is connected to a flow pipe from the deodorizing fan 10, and polluted external air flows in through the deodorizing fan 10. An inlet (not shown) is formed to allow the desulfurized air to be discharged, and an exhaust port (not shown) is formed to discharge the desulfurized external air.

In addition, a catalytic oxidation water storage tank 200 is installed at the bottom of the odor reaction tank 30 so that the desulfurization catalyst used to desulfurize polluted external air in the odor reaction tank 30 can be recycled and recovered.

In FIG. 4, the first valve 35 is configured in the flow path of the odor reaction tank 30 to open or block the flow path with the catalytic oxidation water storage tank 200 for circulation of catalytic oxidation water, and the second valve 65 is It is configured at the outlet of the sodium hypochlorite aqueous solution reaction tank 60 to supply or block the catalyst to the catalyst storage tank 50, and the third valve 75 and fourth valve 85 are connected to the chemical storage tank 70 and water. Each is installed at the outlet of the storage tank 80 to supply or block chemicals or water to the sodium hypochlorite aqueous solution reaction tank 60.

As shown in FIG. 5, the complex deodorizer control system using micronanovertex bubbles according to the first embodiment of the present invention includes a deodorizing fan 10, an air supply device 1, and a micronanovertex bubble generator. (300), a circulation pump (90), a first sensor (21) that detects the concentration of ammonia contained in external air flowing in from an odor generating source through the deodorizing fan (10), and the deodorizing fan (10) A second sensor 22 detects the concentration of hydrogen sulfide contained in the external air flowing in from the odor generating source, and analyzes the ammonia concentration and hydrogen sulfide concentration detected by the first sensor 21 and the second sensor 22. It is composed of a control module 100 that controls system components such as a deodorizing fan, an air supply device, and a circulation pump to remove odor components.

The present invention configured as described above sets the driving speed of the deodorizing fan and the air supply device (1) at low speed when the odor concentration contained in the external air flowing in through the deodorizing fan (10) is low, and at medium speed when the concentration is medium. , in case of high concentration, the operation is controlled at high speed.

However, it is not necessarily limited to these forms of control.

When the odor concentration is low, considering that the external air flowing into the odor reaction tank 30 is small, the operating speed of the air supply device 1 is also set to low so that the corresponding air is supplied to the micro-nanovertex bubble generator 300. As it flows in, micro-nano vertex bubbles are generated to cause material agitation.

On the other hand, when the odor concentration contained in the external air flowing in through the deodorizing fan 10 is high, the driving speed of the air supply device 1 is also adjusted, considering the large amount of external air flowing into the odor reaction tank 30. At high speed, corresponding air flows into the micro-nano-vertex bubble generator 300, thereby generating micro-nano-vertex bubbles and causing material agitation.

The present invention adjusts the amount of external air flowing into the odor reaction tank 30 according to the driving speed of the deodorizing fan 10 and the air supply device 1, and the supply from the air supply device 1 to the micro-nano vertex bubble generator 300. Considering the change in the amount of air used, the control module 100 appropriately controls the circulation pump 90 and performs an operation to control the circulation of the catalytic oxidation water.

As shown in FIG. 6, in the odor concentration level that controls the driving speed of the deodorizing fan 10 and the air supply device 1, the low concentration is 0.05 ppm or less, the medium concentration is 0.05 to 0.1 ppm, and the high concentration is 0.1 ppm. It can be set to ppm or more, and the driving speed of the deodorizing fan (10) and the air supply device (1) can be controlled according to these concentrations.

However, in terms of odor concentration levels, the classification of low, medium, and high concentrations is not necessarily limited to the above concentration values.

In addition, when the concentration is low and the amount of external air is small, the driving speed of the deodorizing fan 10 is controlled to be maintained at low speed, when the concentration is medium and the amount of external air is large, at high speed, and when the concentration is high and the amount of external air is small, the driving speed of the deodorizing fan 10 is controlled. can do. However, these control types are only examples and are not necessarily limited to these conditions.

In the present invention, as shown in FIG. 7, the intermittent operation time of the circulation pump 90 can be set depending on the low, medium, or high odor concentration.

In the case of low and medium concentrations, the operation time can be set to be regulated, and in the case of high concentration, it can be set to operate in full without intermittent operation time.

That is, in the case of low concentration, it can be set to repeat on for 10 seconds and off for 10 seconds, and in the case of medium concentration, it can be set to repeat on for 30 seconds and off for 10 seconds. Additionally, in case of high concentration, it can be set to full operation.

However, in the intermittent operation time, in the case of low and medium concentrations, the operation time is not necessarily limited to the above value.

Meanwhile, in the first embodiment, the driving speed of the air supply device 1 is controlled in proportion to the driving speed of the deodorizing fan 10, but it is not necessarily limited to this control method.

For example, when the odor concentration level is low, the driving speed of the deodorizing fan 10 is set to a low speed, and the driving speed of the air supply device 1 is also set to a low speed, thereby reducing the micro odor in the odor reaction tank 30 corresponding to the low speed.

[Second Embodiment]

Figure 8 is a configuration diagram of a complex deodorizer using micronanovertex bubbles according to the second embodiment of the present invention. Figure 9 is a control configuration diagram of a complex deodorizer using micronanovertex bubbles according to the second embodiment of the present invention.

The second embodiment is configured with an opening/closing valve 15 on the flow path connecting the air supply device 1 and the micro-nanovertex bubble generator 300 in FIG. 2 of the first embodiment.

The opening/closing valve 15 is a valve whose opening/closing amount is controlled by the controller 100. Therefore, the control unit 100 stores and manages the amount of air flowing from the air supply device 1 to the micronanotex bubble generator 300 according to the opening and closing amount of the opening and closing valve 15.

In addition, the control unit 100 stores the speed at which air is supplied from the air supply device 1 to the micronanotex bubble generator 300 and the opening/closing amount of the opening/closing valve 15 in connection with the air supply speed or By appropriately modifying and controlling the opening and closing amount, odor removal from external air flowing into the odor reaction tank 30 is performed efficiently.

Additionally, a display unit 120 may be configured to display the status of the on-off valve 15 controlled by the control unit 100 so that it can be recognized from the outside.

The status of the on-off valve 15 may be information about open or closed, open or closed amount, open time or closed time, etc. Therefore, the manager can control the status of the on-off valve 15 displayed through the display unit 120. You can determine the operation status of the complex deodorizer by checking in real time.

Additionally, a flow sensor 110 may be configured. That is, the amount of air flowing into the micronanotex bubble generator 300 from the air supply device 1 may be detected, processed and analyzed by the control unit 100, and then displayed on the display unit 120.

Therefore, the manager can determine the operating state of the complex deodorizer by recognizing the operating state of the on-off valve 15 and the detected flow rate of the flow sensor 110 through the display unit 120.

In the first embodiment, the air supplied from the air supply device (1) is connected to the deodorizing fan (10) and the air supply device ( The driving speed of 1) is controlled so that the deodorization operation in the odor reaction tank 30 is performed.

At this time, if the odor concentration level changes, the driving speed of the deodorizing fan 10 and the air supply device 1 may also change accordingly. That is, when the odor concentration level decreases, the driving speed of the deodorizing fan 10 and the air supply device 1 can be lowered to a low speed.

On the other hand, the second embodiment controls the driving speed of the deodorizing fan 10 according to the changing odor concentration level, but maintains the driving speed of the air supply device 1 and instead adjusts the opening and closing amount of the valve 15. Control is performed so that air appropriate for the odor concentration level flows into the micronanovertex bubble generator (300).

To explain this in detail, when the odor concentration is high, a large amount of external air is received into the odor reaction tank 30, and the driving speed of the deodorizing fan 10 is controlled at high speed so that the odor can be removed, and the air supply device The driving speed of (1) is also controlled at high speed, and the valve 15 is maintained in a fully open state, allowing a large amount of air to flow into the micronanovertex bubble generator 300 to generate corresponding micronanovertex bubbles. .

On the other hand, when the odor concentration is low, the operating speed of the deodorizing fan (10) is controlled to a low speed so that the odor can be removed while a small amount of external air is received in the odor reaction tank (30), but the air supply device (1) is The driving speed is maintained at a high speed and the opening amount of the valve 15 is reduced to allow air to flow into the micronanovertex bubble generator 300 to generate micronanovertex bubbles suitable for the odor concentration level.

As another example, when the odor concentration is low, the driving speed of the deodorizing fan 10 is controlled to a low speed so that the odor reaction tank 30 can remove a small amount of external air while removing the odor, and the air supply device ( The driving speed of 1) can control the full opening of the valve 15 at regular time intervals while maintaining a high speed.

That is, the valve 15 is closed at regular time intervals to allow air to flow into the micronanovertex bubble generator 300 to generate micronanovertex bubbles appropriate for the odor concentration level.

As another example, the full opening time of the valve 15 can be controlled according to the odor reaction time setting in the odor reaction tank 30.

That is, when the odor reaction is terminated in a short time, micro-nanovertex bubbles are generated from the air supply device (1) even if the odor concentration contained in the external air flowing into the odor reaction tank (30) through the deodorizing fan (10) is low. The valve 15 that supplies air to the device 300 can be kept fully open so that a large amount of air flows into the micronanovertex bubble generator 300 in a short period of time, thereby generating corresponding micronanovertex bubbles.
