The present invention relates to an odor removal device for purifying gaseous and liquid odors using hydraulically generated cavitation bubbles, including ultrasonic and swirl flows.

In a flowing liquid, when the pressure of the fluid is lowered below the vapor pressure in part due to the increase of the flow rate or the decrease of the pressure, the liquid evaporates and bubbles are generated. As described above, the two-phase flow phenomenon in which the liquid phase changes into the gas phase and the liquid phase and the gas phase coexist is called cavitation. The generated cavitation bubbles disappear through shrinkage, re-expansion, and destruction as the flow rate decreases, and the air space formed at the center of the bubble is formed at a high temperature and high pressure of approximately 5,000 K and 500 atm, and the growth and destruction of bubbles It is known to produce highly reactive radicals.

Specifically in South Korea, ammonia (NH ₃ ), methyl mercaptan (CH ₃ SH), hydrogen sulfide (H ₂ S), methyl sulfide ((CH ₃ ) ₂ S), methyl disulfide ((CH ₃ ) ₂ S ₂ ), trimethyl Amine ((CH ₃ ) ₃ N), acetaldehyde (CH ₃ CHO), styrene (C ₆ H ₅ CH = CH ₂ ), volatile organic compounds (VOCs), and the like are designated as odor causing substances.

These odor-causing substances are generated from various sources, such as sewage treatment plants, manure or livestock wastewater treatment plants, landfills, compost plants, chemical plants, various manufacturing industries including food production plants, urban restaurants, and the like. Among them, the sewage treatment plant, manure or livestock wastewater treatment plant, and landfill site are essential living facilities in modern life, and due to the odor generated, the complaints around the installation site are not ceaseless and effective solution of the odor problem is required.

Hereinafter, with reference to the accompanying drawings, the configuration, function and operation of the gaseous malodor and liquid malodor combined odor removing device according to an embodiment of the present invention. However, the same reference numerals for the same or similar components are used uniformly.

1 and 2 show a schematic configuration of a gas odor and liquid odor combined odor removing device according to an embodiment of the present invention.

According to an embodiment, the odor removing device 10 is connected to the main injection pipe 1 into which the fluid is injected, the main injection pipe 1, and the odor injection pipe 2 to inject odor air into the fluid. The fluid injected through the injection tube 1 forms a swirling flow, and the bubble generator 3 generating the cavitation bubbles collides with the fluid discharged from the bubble generator 3 so that the cavitation bubbles are destroyed and flow. It includes a housing portion 4 to form a discharge space 41 to be discharged and an ultrasonic vibrator 5 provided in the housing portion 4, to promote the activation of cavitation bubbles in the discharge space (41).

Fluid is supplied through the main injection pipe (1). At this time, the fluid may be cleanly treated water, such as tap water, the water may further contain a conventional deodorant, oxidizing agent, adsorbent and the like to remove the odor. The fluid is provided in the fluid storage tank T1 and may be pressurized by the fluid pump P1. Or may be provided in the reservoir 81 of the body 8 as described below.

Odor injection pipe (2) is connected to the source of odor gas or connected to the gas storage tank (T2) in which the collected odor gas is stored, odor injection pipe (2) is connected to the main injection pipe (1) to odor to the fluid The gas may be injected or directly connected to the housing part 4 to inject odor gas into the discharge space 41. At this time, the malodorous gas passing through the malodorous injection pipe 2 may be pressurized by the gas pump (P2).

Meanwhile, the bubble generator 3 and the housing part 4 are coupled to each other to form a cavitation generator. The inside of the bubble generator 3 is an approximately cylindrical empty space formed inside the cavitation generator, and fluid is introduced through the main injection pipe 1 connected in the direction in contact with the circumference of the circular cross section. The fluid injected in the circumferential direction of the cylindrical interior of the bubble generator 3 flows through the inner wall surface and forms a swirl flow as indicated by the solid arrow in FIG. 3. The flow velocity is increased by the swirl flow, so that the pressure of the fluid in contact with the inner surface of the bubble generator 3 is lowered and cavitation bubbles start to be generated.

At this time, in order to increase the generation of cavitation bubbles in the bubble generator 3, the inner diameter of the bubble generator 3 may be gradually reduced toward the discharge port (31). 2 and 3, the bubble generating unit 3 having a smaller diameter in two stages is shown, but may be formed of a plurality of stages.

The fluid that forms the swirl flows and proceeds to the outlet, further increases the flow rate as it passes through the small diameter portion, thereby lowering the pressure of the fluid to increase the occurrence of cavitation bubbles.

In addition, a groove 32 may be further formed on the inner wall surface of the bubble generator 3. The groove 32 is to increase the amount of cavitation bubbles due to the sound pressure inside the bubble generator 3, and to generate a finer cavitation bubbles while colliding with the generated cavitation bubbles. Such a groove may be formed by forming a circumferential direction of the inner wall, a direction perpendicular to the circumferential direction, or a lattice shape according to the rotational direction of the swirl flow.

A plurality of outlets 31 are formed on the outer circumferential surface of the bubble generator 3. At this time, when the bubble generator 3 is formed in multiple stages, the outlet port may be formed in the portion having the smallest diameter, although not necessarily. In addition, the outlet 31 may be formed radially along the outer surface of the bubble generating portion. The outlet may be further provided with a nozzle. The fluid is injected into the discharge space 41 formed by the housing part 4 which surrounds the discharge port 31 spaced apart, and the injected gas impinges on the inner wall surface of the housing part 4, so that the cavitation bubbles contained in the fluid are discharged. It is partially destroyed by the impact. Thereafter, the fluid is discharged to one open side of the discharge space.

As the odor injection pipe is connected to the main injection pipe, the odor gas is injected into the fluid in advance. The odor generating material of the odor gas is collected inside the cavitation bubble while the fluid including the odor gas forms a swirl flow in the bubble generation unit. The malodor generating substance collected in the gas space of the generated cavitation bubble is pyrolyzed by the conditions of high temperature and high pressure of the gas space. For example, in the pyrolysis process, the odor-causing substances are thermally decomposed and oxidized in the form of NO ₂ , SO ₂ , CO ₂ , H ₂ O, etc., dissolved in a fluid or discharged together with treated air. This pyrolysis treatment is advantageous for the treatment of volatile odor generating substances which are easily volatilized and collected into the gas space of the cavitation bubbles because the surface of the cavitation bubbles is hydrophobic.

In addition, highly reactive in the interfacial space formed around the gas space of the cavitation bubble Radicals such as hydroxy radicals (OH ·), hydrogen peroxide (H ₂ O ₂ ), hydroperoxy radicals (HO ₂ ·), superoxide radicals (O ₂ ⁻ ·), Odor generating substances are oxidatively decomposed by these powerful oxidation reactions. In such an interfacial space, a high temperature of the gas space may be transferred to perform a pyrolysis treatment and an oxidative decomposition treatment. In such an interfacial space, the oxidative decomposition of the nonvolatile malodorous substances which escape from the gas space without being trapped in the gas space of the cavitation bubble is promoted.

When the fluid is injected from the bubble generating unit and impinges on the inner wall surface of the housing part, the cavitation bubble is destroyed and the activity of radicals is increased by the material transfer, thereby increasing the efficiency of removing the odor generating material described above.

On the other hand, some malodorous gas is directly injected into the discharge space 41 can be removed odor generating material by the fluid containing the cavitation bubbles injected into the discharge space (41). Some cavitation bubbles contained in the fluid collide with the inner wall surface of the housing portion and collapse to greatly activate radicals of the fluid. These fluids and the injected malodorous gas are mixed and the contact area is increased so that the malodor generating material is oxidized or collected in the remaining cavitation bubbles and pyrolyzed.

In addition, the ultrasonic vibrator 5 promotes the activity of the cavitation bubbles in the discharge space (41). The ultrasonic vibrator 5 may be in the form of a cylinder, and is mounted on a housing part that forms a discharge space. The ultrasonic vibrator 5 irradiates ultrasonic waves to the liquid injected into the discharge space 41 to generate cavitation bubbles. As a result, in addition to the cavitation bubbles generated in the bubble generating unit, cavitation bubbles generated by ultrasonic irradiation are additionally generated in the discharge space, so that the thermal decomposition and oxidative decomposition of the malodor generating material by the growth and destruction of the aforementioned cavitation bubbles are more actively promoted. Therefore, the removal efficiency of odor generating substances by cavitation bubbles is increased.

Another embodiment of the present invention includes an ultrasonic vibrator mounted to the main injection tube, odor injection tube, bubble generating unit, the housing portion and the main injection tube. At this time, the main injection pipe, odor injection pipe, bubble generation unit and the housing portion is the same function and action as the above-described embodiment. Characteristic of the malodor removing device according to another embodiment is that the ultrasonic vibrator 5 is provided in the main injection pipe (1).

The ultrasonic vibrator 5 provided in the main injection pipe 1 is formed of a pipe, and the pipe may constitute a part of the main injection pipe. That is, some of the flow paths formed by the main injection pipe 1 are formed of the ultrasonic vibrator 5. Alternatively, the ultrasonic vibrator may be configured to surround the outer circumferential surface of the main injection tube. As a result, bubbles are generated in advance in the fluid before the fluid is injected into the bubble generator, thereby further facilitating the generation of cavitation bubbles.

Furthermore, the ultrasonic vibrator 5 may be connected to the main injection pipe 1 between the odor injection pipe 2 and the main injection pipe 1 is connected to the bubble generating unit (3). In this case, the fluid into which the malodorous gas is injected passes through the ultrasonic vibrator 5. As the cavitation bubble is generated by the ultrasonic vibrator, the odor generating material is collected in the gas space and the interface space of the cavitation bubble, thereby increasing the treatment effect of the odor generating material. On the other hand, the ultrasonic vibrator may be installed in both the bubble generator and the main injection pipe.

1 to 2 and 4, the venturi tube 6 is connected to the main injection tube 1 of the malodor removing device according to the embodiments of the present invention, the malodor injection tube 2 is the venturi tube It can be configured to inject malodorous air into the fluid passing through (6).

In order to increase the amount of cavitation bubbles generated by the swirl flow in the bubble generator 3, it is advantageous that the pressure of the fluid injected into the bubble generator is large. Therefore, the fluid flowing in the main injection pipe 1 may be pressurized by the fluid pump (P1). In order to inject the malodorous gas into the pressurized fluid passing through the main injection pipe 1, since the pressure of the malodorous gas is required to be higher than the pressure of the fluid, the malodorous gas needs to be pressurized through the gas pump P2. At this time, the venturi tube 6 is used to lower the pressure required for the malodorous gas.

The venturi pipe 6 is connected in series to the main injection pipe 1, and the odor injection pipe 2 is connected to a channel 61 having a small diameter where the flow velocity is increased and the pressure is reduced. Therefore, the pressure of the malodorous gas injected into the inside of the fluid whose pressure is reduced while passing through the venturi tube 6 can be lowered than the pressure of the malodorous gas required in the absence of the venturi tube. According to the injection pressure of the odor gas lowered, it is possible to lower the capacity of the gas pump for pressurizing the odor gas and its operating energy.

In addition, as the fluid passing through the venturi tube 6 diffuses at a low pressure at the outlet portion of the narrow channel, the generation of cavitation bubbles is promoted by hydraulic cavitation. Thus, the treatment efficiency of the malodorous gas is increased. This is parallel to the cavitation bubble caused by the vortex cavitation by the swirl flow in the bubble generating unit, the efficiency of the cavitation bubble generation throughout the device.

Meanwhile, referring to FIGS. 1 to 2 and 5 to 6, in the malodor removing apparatus according to the embodiments of the present invention, the point between the malodor injecting pipe 2 is connected to the bubble generating unit 3 is described above. A mixing member 7 installed in the main injection pipe 1 and rotating the fluid while the fluid containing the malodorous gas collides may be further included to mix the malodorous gas and the fluid.

The mixing member 7 is to increase the mixing efficiency of the fluid and malodorous gas, is to break the malodorous gas into small pieces and trapped in the cavitation bubble to help the thermal decomposition or oxidative decomposition to occur efficiently. The mixing member may be a structure that divides the inside of the flow path.

Specifically, the mixing member 7 includes at least one pair of screws 71 twisted in either direction with respect to the center of the main injection pipe 1 as a reference axis, and one screw 71 is a neighboring screw. It may be configured to contact (71) discontinuously.

The screw 71 has a shape twisted in a clockwise or counterclockwise direction in accordance with the advancing direction of the fluid, based on the imaginary center line where the thin plate passes through the center of the circular cross section of the main injection tube.

At this time, the screw 71 can be twisted by at least one quarter rotation to allow the fluid to flow and turn. If the screw is less than 1/4 rotation, the fluid does not turn inside the main injection pipe, rather, the flow rate is greatly reduced according to the flow resistance.

In FIG. 5, the screw 71 is twisted one half turn to create a strong vortex in the fluid, while FIG. 6 is another example, the screw 71 is twisted one quarter turn so that the face of the screw and the fluid The surface resistance according to the contact is lowered.

In addition, the angle A between which the other end 712 of the neighboring screw 71 in contact with one end 711 of one of the screws 71 is in contact with each other may be configured to be staggered by 90 ° from each other. As such, the screws 71 provided in plurality by the angle A between neighboring screws are arranged discontinuously. In addition, by forming an angle of 90 degrees, the circular cross section of the main injection pipe is made to screw both ends with the same area ratio. Since the flow rate moved to the semi-circular space divided by the screw is substantially the same, the fluid exiting the rear end of the screw is not biased in either direction, thereby having the advantage that the flow of the fluid is smooth.

Therefore, the fluid divided while passing through the screw provided in the front according to the direction of the fluid is divided again by one end of the screw installed in the rear end. This division of the fluid is carried out several times by the front end of each screw, so that the gas mass of the malodorous gas is finely divided. As a result, the broken malodorous gas increases the contact area and the contact opportunity with the fluid or the cavitation bubble, thereby increasing the removal efficiency of the malodor generating substance.

In addition, since each screw is rotated in the same direction, the fluid is rotated according to the direction of rotation of the screw. After passing through this mixing member, the fluid is pivoted in the main injection pipe and can flow quickly. As a result, the flow rate of the fluid injected into the bubble generating unit can be further increased, and the generation efficiency of the cavitation bubbles is increased further according to the increase in the flow rate of the swirl flow.

Referring again to FIG. 1, the bubble generating unit 3 and the housing unit 4 are installed inside the sealable body 8. The lower part of the main body 8 is formed with a reservoir 81 for collecting the fluid discharged from the discharge space. In addition, the gas discharged from the discharge space rises and is discharged to the gas discharge line 82 provided in the upper portion of the main body (8).

At this time, the main body 8 may be further provided with a reprocessing unit 83 for removing odor generating substances remaining in the gas. The reprocessing unit 83 may be composed of members that remove odor generating substances remaining therein while the rising gas passes therethrough.

In detail, the reprocessing unit 83 may include a carrier cartridge 831, a water spray body 832, and an adsorption cartridge 833. The carrier cartridge 831 includes a case formed of a substantially hexahedron and a plurality of carriers contained in the case. The water spraying body 832 receives a fluid collected in the storage water or a fluid supplied from the outside and sprays the upper portion of the carrier cartridge. The adsorption cartridge 833 is made of a case and an adsorbent such as activated carbon contained in the case.

As the gas rises, the fluid sprayed from the water sprayer 832 contacts the carrier of the carrier cartridge 831, which is wet, and odor generating substances remaining in the gas are adsorbed or biologically decomposed and removed. The gas passing through the carrier cartridge 831 is mixed with the sprayed water particles to collect odor generating substances remaining in the gas. In addition, the gas adsorbs the odor generating substances remaining while passing through the adsorption cartridge 833. In addition, the reprocessing unit may further include various filter layers such as a microorganism active layer.

The reservoir 81 is in communication with the main injection tube 1 by the recovery pipe 811, whereby the fluid of the reservoir 81 can be re-injected into the bubble generator (3). The fluid collected in the reservoir 81 may contain cavitation bubbles that have not been destroyed, and these fluids are recycled to remove odorous substances while passing through the venturi tube, the ultrasonic vibrator, the mixing member, and the bubble generator. Therefore, it is possible to reduce the flow rate required for the operation of the continuous odor removing device.

In addition, since the fluid provided in the storage tank of the main body (hereinafter, referred to as storage water) is recycled to generate cavitation bubbles, even if odorous substances are already dissolved in the storage water, they can be removed through the odor removing device.

Referring to Figure 7 will be described a gas-like odor and liquid odor combined odor removing device according to another embodiment of the present invention. Another embodiment of the present invention includes a main injection tube, odor injection tube, bubble generation unit, housing unit and ultrasonic vibrator. In addition, it may further include a venturi tube or a mixing member. Since these components are redundant with the above description, a detailed description thereof will be omitted.

Gas odor and liquid odor combined odor removing device according to another embodiment of the present invention stores the fluid, the main injection pipe (1) is connected to the fluid storage tank for supplying a fluid to the main injection pipe (1) (T1) and a conveying line 813 for moving the fluid discharged from the housing portion 4 to the fluid storage tank (T1), by recycling the storage water discharged from the housing portion 4 to remove odors It is characterized by a continuous odor removal in the apparatus.

In detail, the conveying line 813 communicating with the fluid storage tank T1 is connected to the fluid discharge line 812 which discharges the stored water collected in the storage tank 81 to the outside of the main body. Therefore, the storage water collected in the storage tank 81 may be recovered to the fluid storage tank T1 again through the transfer line 813. At this time, by adjusting the valve of the fluid discharge line and the valve of the conveying line, some of the storage water is returned to the fluid storage tank to be reused as a fluid injected into the main injection pipe, and the remaining storage water may flow out.

That is, the odor causing liquid is stored in the fluid storage tank (T1), the odor causing liquid is supplied from the fluid storage tank (T1) to the main injection pipe (1), and improves the removal efficiency of the liquid odor-causing substances as necessary Some of the liquid collected in the reservoir under the bubble generating unit in the odor removing device to discharge, part is returned to the fluid storage tank and recycled to treat the liquid odor generating material through a continuous process.

At this time, by installing the storage tank (T3) on the conveying line can be stored for a while the storage water containing the cavitation bubbles and odor generating material. As a result, the residence time necessary for the thermal decomposition and oxidative decomposition of the malodor generating substance by the cavitation bubble can be secured, and the treatment efficiency of the malodor generating substance is increased. In addition, a fluid pump (not shown) may be further provided between the storage tank T3 and the fluid storage tank T1.

At this time, since it may contain a suspended solid according to the characteristics of the malodor-causing liquid, the water spray body 832 and the carrier cartridge 831 can be removed. Alternatively, the water sprayer 832 and the carrier cartridge 831 may be included as it is, and the water supplied to the water sprayer 832 may be supplied with cleanly treated water such as tap water.
