Hereinafter, with reference to the accompanying drawings, the configuration, function and operation of the malodor treatment apparatus according to an embodiment of the present invention will be described. However, the same reference numerals for similar or identical components are used uniformly.

Referring to FIG. 1, a treatment main body 10 for purifying malodorous air supplied by using cavitation bubbles generated from a fluid, filtering and discharging the malodorous air separated after the purification process, and the treatment It includes a filtration main body 20 for receiving the fluid collected in the lower portion of the main body 10 to filter the particles contained in the fluid, and to provide a fluid to the processing body (10).

In the treatment body 10, cavitation bubbles are generated using a fluid. In this case, the fluid may be water. At this time, the cavitation bubble is a liquid is evaporated when the pressure of the fluid is partially lower than the vapor pressure due to the increase in the flow rate or decrease in the pressure in the fluid to generate bubbles. At this time, the phase is changed from the liquid phase to the gas phase, and the liquid phase and the gas phase coexist. 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.

The malodorous component of the malodorous air is collected inside the cavitation bubble generated by the malodorous air mixed fluid. The malodorous components collected in the gas space of the generated cavitation bubbles are pyrolyzed by the conditions of high temperature and high pressure of the gas space. For example, in the pyrolysis process, odor components are thermally decomposed and oxidized in the form of NO ₂ , SO ₂ , CO ₂ , H ₂ O, and the like, dissolved in a fluid or discharged with bubbles. This pyrolysis treatment is advantageous for the treatment of volatile odorous components that 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 ⁻ ·)) The odor component is oxidatively decomposed by a strong oxidation reaction, in which the high temperature of the gas space is transmitted, and the pyrolysis treatment and the oxidative decomposition treatment of the odor component can be carried out together. Rather, it promotes oxidative decomposition of nonvolatile malodorous components exiting the gas space.

The treatment main body 10 is mounted to the treatment main body 10, and the supplied fluid forms a swirl flow and is installed at the lower part of the cavitation generating unit 11 to generate cavitation bubbles. And a drop edge 12 for delaying the flow of the fluid discharged from the cavitation generating unit 11 to the bottom of the processing body, and included in the rising air provided on the upper portion of the cavitation generating unit 11. A reprocessing unit 13 for removing the odor component is included.

The cavitation generator 11 generates swirl flow in the supplied fluid to lower the pressure of the fluid, thereby generating cavitation bubbles.

2 and 3, the cavitation generating unit 11 forms a swirl flow, and the bubble generating unit 111 generates cavitation bubbles in the fluid, and is discharged from the bubble generating unit 111. The housing part 112 includes a housing in which the fluid collides, the cavitation bubble is broken and flows, and forms a discharge space in which one end is opened.

The inside of the bubble generator 111 is formed with a substantially cylindrical empty space. A fluid pressurized by a pump or the like is supplied in a direction in contact with the circumference of the circular cross section. The fluid injected into the bubble generator 111 flows through the inner wall, and forms a swirl flow as indicated by the solid arrow in FIG. 3. This swirl flow increases the flow velocity of the fluid, thereby lowering the pressure of the fluid in contact with the inner surface of the bubble generator 111 and begins to generate cavitation bubbles.

At this time, in order to increase the generation of cavitation bubbles in the bubble generator 111, the inner diameter of the bubble generator 111 is formed to gradually decrease toward the discharge port (111a). In FIG. 2 and FIG. 3, the bubble generating unit 111 having a diameter smaller in two stages is illustrated, but may be formed to gradually decrease in diameter in a plurality of stages.

While forming the swirl flow and proceeding to the outlet 111a, the fluid is further increased while passing through the small diameter portion. The lower pressure of the fluid thus greatly increases the occurrence of cavitation bubbles.

A plurality of outlets 111a are formed on the outer circumferential surface of the portion formed with a small diameter, so that the fluid containing the cavitation bubbles is discharged through the outlets 111a. In this case, the outlets 111a may be radially formed on the outer circumferential surface of the bubble generator 111 so that the fluid may be radially injected.

The housing part 112 surrounds the outer circumferential surface of the bubble generating part in which the outlets 111a are formed to be spaced apart, thereby forming a discharge space 112a in which the fluid injected from the outlet 111a is accommodated. One end of the discharge space 112a may be opened to allow the fluid to escape to the outside.

As the fluid injected into the discharge space 112a collides with the inner wall surface of the housing part 112, the cavitation bubbles contained in the fluid are partially destroyed by the impact. At this time, as the cavitation bubbles are destroyed, the activity of radicals is increased by material transfer, and the removal efficiency of the odor component described above is increased.

Referring back to Figures 1 to 3, the injection of odor air according to the present invention can be made through three routes. First, malodorous air may be injected into the fluid supplied to the bubble generator 111 in advance. Second, odor air may be injected into the discharge space 112a of the housing part 112. In this case, the malodorous air may be mixed with the sprayed fluid containing radicals having increased activity in the discharge space 112a and purified. Third, the malodorous air may be injected into the filtration main body 20 as described below, and may be supplied to the bubble generating unit by a pump together with the fluid of the filtration main body.

Injecting malodorous air through any one of these routes, or injecting malodorous air through the other routes except for any one root, or injecting malodorous air using all three routes. Hereinafter, each route is demonstrated.

First, malodorous air may be injected into the fluid in the middle of the pipe for supplying the fluid to the bubble generator. At this time, the odor air may be injected into the fluid through the venturi tube provided in the pipe. In FIG. 1 and FIG. 2, a channel having a diameter smaller than that of the fluid passing through the venturi tube V is formed, and a pipe to which malodorous air is supplied is connected to the channel.

By using the venturi tube (V), it is possible to lower the pressure of the malodorous air injected into the fluid conveyed at high pressure by the pump. Therefore, even if a separate pump for compressing malodorous air sucked in a restaurant or the like is not required, or a pump for additionally compressing malodorous air is required, it is possible to inject malodorous air with a low capacity pump. This reduces equipment costs and operating costs.

In addition, as the fluid passing through the venturi tube V diffuses at a low pressure at the outlet portion of the narrow channel, the generation of cavitation bubbles is promoted by hydraulic cavitation. Therefore, the treatment efficiency of odor air is raised. This is in parallel with the cavitation bubbles caused by the vortex cavitation by the swirl flow in the bubble generating unit, the cavitation bubble generating efficiency in the entire cavitation generating unit is increased.

Second, odor air is injected into the discharge space 112a formed in the housing 112. In this case, it is possible to remove the odor component activated in the discharge space (112a). In this case, it is easy to construct a pipe in parallel with the injection route of the malodorous air described above. In addition, in the case of a large store with a large flow rate of odor air, some are injected into the fluid, and the other is injected into the discharge space, so that the processing capacity can be easily increased while using a cavitation generating unit having a predetermined capacity.

Third, the malodorous air is injected into the filter main body 20 and then mixed with the fluid of the filter main body 20 and injected into the bubble generator 111. In this case, a continuous operating cycle is established under the same conditions in which the fluid inflow amount inside the filter main body 20 and the fluid outflow amount by the pump are comparable. In this case, since the fluid and odor air are sucked together by the pipe, the mixture of the fluid and the odor air is more effective.

In addition, although not shown, an additional pipe and pump for supplying fluid to the bubble generating unit may be added by pumping the bottom of the processing body for stable operation of the bubble generating unit.

When the malodorous air is mixed in advance with the fluid introduced into the bubble generating unit 111 among the above-described routes, as shown in FIG. 2, the pipe L1 includes a mixing member P for finely dividing the malodorous air in the fluid. It may be further included.

Mixing member (P) is to rotate the fluid while colliding the fluid containing malodorous air, and breaks the malodorous air finely to promote the trapped in the cavitation bubble of the malodorous component. Specifically, the mixing member P includes at least one pair of screws S twisted in either direction with respect to the center of the pipe as a reference axis, and one of the screws S is discontinuous with the neighboring screws S. It may be configured to contact with.

The screw S has a shape twisted in a clockwise or counterclockwise direction depending on the traveling direction of the fluid, based on the imaginary center line through which the thin plate passes through the center of the circular cross section of the pipe.

At this time, the screw (S) is twisted at least one quarter rotation to flow through the fluid. 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.

One end of one of the screws (S) and the other end of the adjacent screw (S) in contact with it may be perpendicular to each other. As such, the malodorous air in the fluid is divided several times by the front end of every screw due to the discontinuous arrangement between neighboring screws. As such, the finely divided malodorous air increases the contact area and the contact opportunity with the fluid or the cavitation bubble, thereby increasing the removal efficiency of the malodorous component.

In addition, since each screw S is rotated in the same direction, the fluid is rotated in accordance with the rotation direction of the screw. After passing through this mixing member, the fluid is pivoted in the 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.

On the other hand, the dropping edge portion 12 allows the fluid discharged from the cavitation generating unit 11 mounted in the middle of the treatment body to be slowly moved to the lower portion of the treatment body 10 to maximize the efficiency by increasing oxidative decomposition and pyrolysis. will be.

1, 4 to 5, the dropping edge portion 12 is installed inclined in the interior of the treatment body 10, at least one first inclined plate (1) having a first outlet (122) formed at the lower end ( 121, and spaced apart from the first inclined plate 121, inclined to be opposite to the first inclined plate 121, and provided with a second outlet 124 at a lower end thereof. At least one second slope plate 123 is included.

The treatment body 10 may have a cylindrical shape. The first inclined plate 121 and the second inclined plate 123 are mounted to the upper surface of the processing body 10 so as to be inclined.

At the lower end of the inclined first inclined plate 121, a first outlet 122 through which the fluid flowing on the upper surface of the first inclined plate 121 flows out is formed.

The second inclined plate 123 has an inclination opposite to that of the first inclined plate 121 and is spaced apart from the first inclined plate 121 at a lower portion of the first inclined plate 121. The uppermost part of the second inclined plate 123 is located under the first outlet 122. In addition, the lowermost part of the second inclined plate 123 faces the first outlet 122, and a second outlet 124 is formed through which the fluid flowing through the upper surface of the second inclined plate 123 flows out.

A plurality of first inclined plate 121 and second inclined plate 123 may be mounted alternately. In FIG. 1, four first inclined plates 121 and three second inclined plates 123 are illustrated. The quantity of the first inclined plate 121 and the second inclined plate 123 may vary depending on the capacity of the treatment body.

The fluid discharged from the cavitation generating unit descends while sequentially moving the upper portions of the first inclined plate and the second inclined plate. Therefore, it is possible to lengthen the time it takes for the fluid to reach the bottom surface of the treatment body, thereby additionally removing residual odor components by the cavitation bubbles remaining in the fluid. Therefore, the removal efficiency of the odor component can be increased.

In addition, a plurality of protruding plates 125 elongated in a direction perpendicular to the flow direction of the fluid may be provided on the upper surface of the first inclination plate 121 or the second inclination plate to be spaced apart from each other. As the protrusion plate 125 protrudes perpendicular to the flow direction of the fluid, the flow resistance increases on the upper surfaces of the inclined plates. Therefore, the flow rate of the fluid can be further lowered, thereby allowing a longer time for the remaining malodorous component to be processed by the cavitation bubbles.

In addition, referring to FIG. 5, one end of the protruding plate 125 in the longitudinal direction is opened, and the other protruding plate 125 is open at the other end of the protruding plate 125 in the opposite direction to the protruding plates 125. Thereby, a zigzag flow path through which the fluid flows may be formed.

In this case, the fluid can flow along the zigzag flow path formed by the protrusion plate. When the flow rate is high, a portion of the fluid is moved to the outlet directly beyond the protrusion plate, and a portion flows along the zigzag flow path to further lower the flow rate of the entire fluid.

In addition, since the fluid does not stagnate between the protrusions, particles such as dust are moved together with the fluid without remaining between the protrusions. Therefore, even if it is operated for a long time, the particles do not accumulate between the protrusions, it is possible to maintain the effect of the flow rate decrease by the protrusions.

Such a protruding plate may be provided in both the first and second inclined plates. Alternatively, the first inclination plate or the second inclination plate may be selectively provided. Alternatively, the inclined plates may be selectively formed on some of the inclined plates.

Referring back to FIG. 1, the reprocessing unit 13 is a member that removes the odor component remaining as the air discharged from the cavitation generating unit 11 rises.

The reprocessing unit 13 rises by contacting the rising air by spraying water on the tin cartridge 131 containing a plurality of carriers wetted with a fluid in which the malodorous substances contained in the air are collected, and the tin cartridge 131. It includes a water spray body 132 for cleaning the odorous substances contained in the air. In addition, it may further include an adsorption cartridge 133 that is spaced apart on the water spraying body 132 and contains an adsorbent for adsorbing malodorous substances contained in the rising air.

The tin cartridge 131 includes a cylindrical case having an empty space formed therein, and a plurality of tin filled in the case. At this time, the upper and lower surfaces of the case may be made of a mesh of the size of the discharged air flows without leaving the tin. In addition, the tint may be, for example, a piece of styrofoam, the surface of the tint is wet with water sprayed from the water spraying body (132).

The discharged air passing through the tin cartridge 131 is cleaned by reacting with the water odor component remaining in the discharged air while contacting wet water on the surface of the tin cartridge.

Material such as natural rock, ceramic, synthetic resin may be used as the tin, and it is preferable to use a porous tin with a wide specific surface area of the tin to widen the contact area of the discharged air and to efficiently remove residual odor components.

The porous tin may further include a deodorant, an oxidizing agent, an adsorbent, and the like, and specifically, silica (SiO ₂ ), alumina (Al ₂ O ₃ ), iron oxide (Fe ₂ O ₃ ), zinc oxide (ZnO), cadmium sulfide ( CdS), tungsten oxide (WO ₃ ), polyacrylic acid (Polyacrylic acid, PAA), silver nanoparticles and combinations thereof may further include any one selected from the group consisting of. In addition, a microbial film may be formed on the surface of the tin to adsorb and remove residual contaminants.

On the other hand, the water spray body 132 includes a pipe member which is installed spaced apart from the upper portion of the charging cartridge, and a plurality of spray nozzles formed in the pipe member.

Specifically, the water spray body 132 may be composed of a plurality of branch pipes provided with a plurality of main pipes receiving water from the outside of the main body, and a plurality of nozzles communicating with the main pipes and spraying water downward. Water particles formed by the sprayed water are mixed with the rising exhaust gas to remove odor generating substances remaining on the exhaust gas. In this case, the water sprayed from the water spray body 132 may be a fluid discharged from the cavitation generating unit (11).

On the other hand, the adsorption cartridge 133 is installed spaced apart on the water spray body (132). The adsorption cartridge includes the aforementioned cylindrical case and an adsorbent filled therein. At this time, the upper and lower surfaces of the case may be a mesh woven to a size that does not leave the adsorbent to the outside.

The adsorbent is composed of a material having a large surface area per unit volume such as activated carbon, alumina, and charcoal. The remaining odor component is removed by adsorbing the adsorbent while the discharged air passes through the adsorption cartridge. The adsorbent can be used, for example, as long as it is commonly used as an adsorbent, specifically, activated carbon (charcoal), silica (SiO ₂ ), alumina (Al ₂ O ₃ ), iron oxide (Fe ₂ O ₃ ), and combinations thereof. Any one selected from the group consisting of can be used. The adsorbents are preferred in that porous materials having a large surface area can form a contact area to increase odor removal efficiency.

The adsorbent may further include a deodorant, an oxidizer, an adsorbent, and the like, and specifically, silica (SiO ₂ ), alumina (Al ₂ O ₃ ), iron oxide (Fe ₂ O ₃ ), zinc oxide (ZnO), and cadmium sulfide (CdS). ), Tungsten oxide (WO ₃ ), polyacrylic acid (Polyacrylic acid, PAA), silver nanoparticles and combinations thereof may further include any one selected from the group consisting of.

Such a reprocessing unit may be made of only a light cartridge and a water spray body, or may be made of only an adsorption cartridge. Alternatively, various filter layers such as the active cartridges of the microorganism may be further included in addition to the above-described tin cartridge, water spray and adsorption cartridge. In addition, the stacking order of the cartridge, the water spraying body, the adsorption cartridge and the like can be changed.

1 and 6 show the filtration body.

The filter main body 20 includes a housing 21 having a discharge port formed at one side thereof, and a filter unit 22 into which a fluid collected at a lower portion of the treatment main body flows inside the housing 21.

The housing 21 is a cylindrical member having a circular or polygonal cross section. A discharge port 211 is formed at one side of the housing 21, and a pipe L1 communicating with the cavitation generating unit is connected to the discharge hole 211.

The filter unit 22 is provided inside the housing 21. The filter unit 22 is formed inside the housing, and may have an empty space therein surrounded by a filter membrane. The filter membrane may be a known structure or material such as a mesh or a nonwoven fabric.

The pipe L2 communicating with the lower part of the treatment body 10 is connected to the inside of the filter part 22. The pipe (L2) may be further provided with a pump for the transfer of the fluid. The pump can be omitted if the filtration body is located below the treatment body.

The fluid collected in the lower portion of the treatment body 10 passes through the filter portion 22 to filter the particles contained in the fluid. At this time, the particulate matter is a compound or the like that enters with the odor air and sinks to the salt due to agglomerated dust or cavitation bubbles. The fluid filtered through the filter unit 22 accumulates inside the housing 21, flows out to the outlet 211, enters the cavitation generating unit, and is recycled to the treatment body.

In addition, the lower portion of the filter unit 22 is in communication with, and may further include a trap unit 23 having a trap space 23 for storing the particles filtered by the filter unit.

Particles filtered by the filter unit 22 are dropped and stored in the trap space 23 communicated with the lower part of the filter unit. Therefore, the filter unit 22 is not blocked by the particles, it is possible to maintain a constant filtration performance.

In addition, the trap 23 is detachably coupled to the housing 21.

In FIG. 6 a trap portion 23 is shown detachably coupled to the open lower part of the housing. The trap part 23 is a cylindrical member, and the through-hole is formed in the center part of an upper surface, and the filter part is attached to the periphery of this through-hole. The lower part of the filter part 22 communicates with a through hole.

The outer circumferential surface of the trap unit 23 and the lower end of the inner circumferential surface of the housing 21 are coupled by screwing. At this time, a packing for sealing is further coupled between the trap part 23 and the housing 21. The trap 23 and the housing 21 may be detachably coupled through a known coupling means such as a clamp in addition to screwing.

In this case, after the user operates the malodor treatment apparatus for a certain period of time, the trap part can be separated from the housing, and the filter part can be removed from the trap part to remove particles accumulated in the filter part. Therefore, it is easy to remove the collected particles.

In addition, the filter unit 22 may further include an auxiliary filter unit 24 installed between the inner wall surface of the housing 21 and filtering foreign matter contained in the fluid passing through the filter unit 22. Can be.

The auxiliary filter part 24 is a member that can additionally filter out fine foreign matter remaining in the fluid filtered by the filter part 22. The auxiliary filter part 24 may be provided as a plate member that borders between the filter part 22 and the inner wall surface of the housing 21. In FIG. 6, the auxiliary filter part 24 is illustrated in a cylindrical shape surrounding the circumference of the filter part 22. In this case, when the lower end of the sub-filter unit 24 is blocked for a long time, the water level inside the sub-filter unit 24 increases, and filtering is performed on the upper part of the sub-filter unit 24 in accordance with the elevated water level. Since it is possible to pass through the sub-filter unit 24, the worry of clogging the sub-filter unit due to long use is reduced.

In the embodiment of the present invention the fluid is circulated through the treatment body and the filter body. Since cavitation bubbles remain in the fluid circulating while passing through the cavitation generation unit, the odor air may be further purged by the cavitation bubbles remaining during the recirculation.
