FIG. 3 is an enlarged view of an exhaust cleaning unit main body shown in FIG. 2. FIG. 4 is an enlarged view of the vicinity of a hoisting R plate shown in FIG. 3.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram of a deodorizing apparatus according to the present invention.
The deodorizing apparatus 11 according to the present embodiment is roughly divided into an exhaust cleaning unit 13 and a sewage electrolysis unit 15. The exhaust cleaning unit 13 includes an exhaust cleaning unit main body 17.

2A is a front view of the exhaust cleaning unit main body 17 shown in FIG. 1, and FIG. 2B is a side view thereof.
The exhaust cleaning unit main body 17 includes a mixed water tank 21 filled with water 19 in the lower part, and is formed in an airtight structure. An air supply chamber 23 is defined inside the exhaust cleaning unit main body 17. The air supply chamber 23 is supplied with contaminated exhaust 27 from an air supply port 25 connected to the exhaust cleaning unit main body 17 and is opened in the water of the mixed water tank 21.

  In the present embodiment, a sewage recovery tank 31 communicates with the mixed water tank 21 via a water level balance return pipe 29. The dirty water 19 separated from the contaminated exhaust 27 in the cleaning chamber 33 described later is recovered in the dirty water recovery tank 31. The mixed water tank 21 and the sewage recovery tank 31 may have a single configuration.

FIG. 3 is an enlarged view of the exhaust cleaning unit main body 17 shown in FIG.
Inside the exhaust cleaning unit main body 17, a cleaning chamber 33 that is defined as the air supply chamber 23 and is opened in the water of the mixed water tank 21 is provided. The cleaning chamber 33 has an exhaust port 35 on the upper side. A filter unit 37 is provided above the exhaust cleaning unit main body 17. Further, an exhaust fan 39 is provided above the exhaust cleaning unit body 17, and the exhaust fan 39 exhausts the air 41 in the cleaning chamber 33 from the exhaust port 35. That is, in the cleaning chamber 33, when the exhaust fan 39 is driven, the air 41 passes through the filter portion 37 and is sucked and discharged from the exhaust port 35. The filter unit 37 removes moisture in the rising polluted exhaust gas. As the exhaust fan 39, for example, a fan capable of securing an air volume of about 50 to 100 m ³ / min is used.

  A drooping plate 47 is provided between the air supply chamber 23 and the cleaning chamber 33 to partition the air supply chamber water surface 43 of the air supply chamber 23 and the cleaning chamber water surface 45 of the cleaning chamber 33 into water. Therefore, the air supply chamber 23 and the cleaning chamber 33 are not communicated with the water 19 in the mixed water tank 21. On the other hand, when the exhaust fan 39 is driven and the cleaning chamber 33 becomes negative pressure, the water supply chamber water surface 43 is lowered, and the contaminated exhaust 27 of the supply chamber 23 flows into the cleaning chamber 33 through the hanging plate 47. Become.

  Although not shown in the figure, the hanging plate 47 has a lower edge formed in a sawtooth shape (a jagged shape), and is arranged and set so that half of the sawtooth and the upper portion become the water supply chamber water surface 43 when the exhaust fan 39 is in operation. ing.

FIG. 4 is an enlarged view of the vicinity of the winding R plate shown in FIG.
In the mixing water tank 21 of the cleaning chamber 33, a winding R plate 49 is provided in the vicinity of the hanging plate 47. The hoisting R plate 49 rotates the contaminated exhaust 27 that flows into the cleaning chamber 33 through the drooping plate 47 from the air supply chamber 23 due to the negative pressure of the cleaning chamber 33 so as to be stirred with the water 19 by rotating along the concave curved surface. work. That is, the water 19 and the polluted exhaust 27 are mixed by the drooping plate 47 and the hoisting R plate 49 and mixed.

  In the cleaning chamber 33, a moisture adhesion separator 51 is provided. The moisture adhering / separating device 51 alternately protrudes the baffle plates 55 with a downward inclination from the facing wall 53 to form a bent channel 57, and removes moisture from the colliding ascending air current as water droplets 59. The moisture adhesion separator 51 has a so-called eliminator action, prevents the water 19 from being scattered along with the flow of the air 41, and removes moisture using the inertial force of the water 19.

  The contaminated exhaust 27 rising from the hoisting R plate 49 toward the exhaust port 35 contains water 19 in the form of a mist. This mist is mixed with volatile organic compounds in the polluted exhaust gas. In the moisture adhering / separating device 51, the polluted exhaust 27 containing the water 19 in the form of mist passes through the bent flow path 57 formed by the baffle plate 55, so that water droplets are obtained using the inertial force of the water 19. 59 and air 41 are separated. That is, the contaminated exhaust 27 is divided into dirty water droplets 59 and clean air 41, and the volatile organic compounds in the contaminated exhaust gas are removed together with the water droplets 59 as dirty water. In this manner, in the cleaning chamber 33, the moisture in the polluted exhaust gas that is mixed and raised with the water 19 in the mixed water tank 21 is attached by the obliquely inclined baffle plate 55 to be enlarged as the water droplet 59, and can be dropped and removed. . Thereby, the odor of the contaminated exhaust 27 can be greatly reduced.

  A cleaning shower pipe 61 may be provided in the cleaning chamber 33. The cleaning shower pipe 61 is attached to the base end side of the baffle plate 55 and jets water 19 toward the bent flow path 57. The water 19 can be supplied to the washing shower pipe 61 by connecting the shower pump 63 to the mixed water tank 21 and supplying the water 19 in the mixed water tank 21 via the shower filter 65. By providing the cleaning shower pipe 61, it is possible to further enhance the action of separating the particulates and contaminated dust to which the volatile organic compound is adhered from the contaminated exhaust 27 rising in the cleaning chamber 33.

  The mixed water tank 21 is preferably separated from the sewage recovery tank 31 at least in the upper layer. This is because the water droplet 59 to which the volatile organic compound adheres falls. As in the present embodiment, by allowing the dropped water droplet 59 to flow into the sewage collection tank 31, the volatileity contained in the water droplet 59 immediately after dropping at the mixing portion between the drooping plate 47 and the hoisting R plate 49. It is possible to prevent the organic compound from mixing with the water 19 and adhering to the mist.

  As shown in FIG. 1, in the deodorizing apparatus 11, the sewage electrolysis unit 15 is preferably connected to the exhaust cleaning unit 13. The sewage electrolysis part 15 deposits the sludge 67 from the sewage sent from the sewage collection tank 31 by electrolysis. The sewage electrolysis unit 15 has an electrolytic cell 69 for this purpose. Below the electrolyzer 69, sewage from the sewage recovery tank 31 is supplied by a sewage supply pump 71. A supply valve 73 is provided between the sewage supply pump 71 and the electrolyzer 69, and the sewage recovery tank 31 and the electrolyzer 69 can be controlled and shut off. Further, a drain valve 75 is provided below the electrolytic cell 69, and the sediment accumulated at the bottom of the electrolytic cell 69 can be collected by opening the drain valve 75.

  The electrolytic cell 69 is provided with an electrode set 81 in which a plurality of parallel anode aluminum 77 and cathode stainless steel 79 are alternately arranged. In the electrolytic cell 69, when a direct current is applied to the electrode set 81, the sewage is simultaneously oxidized and reduced to be electrolyzed. Dirty water 19 from the mixed water tank 21 is sent to the sewage electrolysis unit 15 and is purified by the action of being oxidized and reduced by rising between the electrode sets and the action of agglomeration of aluminum hydroxide eluted from the anode. It is separated into water 19 and sludge 67. That is, the contaminants from the contaminated exhaust 27 mixed in the water of the mixed water tank 21 can be removed as the sludge 67.

  A scraper 83 is moved above the electrolytic cell 69 by a fluid pressure cylinder 85 in a direction along the electrolytic cell surface. By moving the scraper 83, the sludge 67 that has floated on the surface of the electrolytic cell is scraped and collected in a floating sludge collection tank 89 that includes a draining filter cloth 87. A drain valve 91 is provided below the floating sludge collection tank 89, and the water 19 dehydrated from the sludge 67 is drained as drain water. Since the sludge 67 to which the volatile organic compound is adhered is removed, the drain water can be recirculated to the mixed water tank 21 because of less odor.

  A return tank 93 is attached to the upper part of the electrolytic tank 69, and water 19 that does not contain sludge 67 below the electrolytic tank water surface on which the sludge 67 floats flows into the return tank 93. A water surface adjustment plate 95 is attached to the return tank 93. A return pipe 97 is connected to the outside of the water surface adjustment plate 95, and the return pipe 97 communicates with the mixed water tank 21. That is, the sludge 67 is removed from the sewage in the mixed water tank 21, and clean sludge removal water 99 is returned to the mixed water tank 21 again.

  Thereby, the water 19 of the mixed water tank 21 is maintained at a constant cleanliness, and the deodorizing ability of the contaminated exhaust 27 can be maintained constant. In this way, since the water 19 in the mixed water tank 21 is refluxed after the sludge 67 is removed by the sewage electrolysis unit 15, the water 19 in the mixed water tank 21 can be reused again as clean sludge removal water 99, and the operating cost is increased. Can be reduced.

Next, the operation of the deodorizing apparatus 11 having the above configuration will be described.
In the deodorizing apparatus 11, when the exhaust fan 39 is driven, the air supply chamber 23 is at atmospheric pressure to a positive pressure, and the cleaning chamber 33 is at a negative pressure. Thereby, the air supply chamber water surface 43 is lowered, and the air supply chamber water surface 43 is near the lower edge of the hanging plate 47. The contaminated exhaust 27 taken in from the air supply port 25 is decelerated in the air supply chamber 23 and is wound into the cleaning chamber 33 together with the water 19 from the air supply chamber water surface 43 by the hoisting R plate 49 as shown in FIG. The passing wind speed of the hanging plate 47 is set to 20 to 40 m / s, for example.

  In the winding R plate 49, a collision occurs immediately after passing through the sawtooth portion of the drooping plate 47, that is, immediately after being sucked into the cleaning chamber 33, resulting in a collision, and passing through the narrow portion and the R surface. Moisture is splashed by the impact of the collision, resulting in a mixed stirring state that efficiently catches fine particles and contaminated dust in the contaminated exhaust.

  At this time, since the upper side of the hoisting R plate 49 is a downward surface, the contaminated exhaust 27 and the water 19 are more efficiently agitated. The same reasoning that must be stirred to mix the powder and water 19. The negative pressure of the cleaning chamber 33 acts on the combination of the passage of the sawtooth portion and the hoisting R plate 49, and the contaminated exhaust 27 is mixed with the water 19 and pulled up above the hoisting R plate 49. This position (mixing part) is also cleaned. The mixed water 19 and contaminated exhaust 27 are sucked into the cleaning chamber 33. This water 19 is in a state where volatile organic compounds are caught. The sewage that has not risen in the mixing section sinks into the mixed water tank 21. The sunk sewage (dust etc.) is collected from the mixed water tank 21 (bottom) every predetermined operating time.

  The contaminated exhaust 27 is divided into water droplets 59 and air 41 that are contaminated by the moisture adhesion separator 51. That is, the water droplet 59 is adhered by the baffle plate 55 of the moisture adhesion separator 51 to be enlarged as the water droplet 59 and removed by dropping. In addition to this, the cleaning shower pipe 61 further enhances the action of separating fine particles and contaminated dust to which volatile organic compounds adhere from the contaminated exhaust 27 rising in the cleaning chamber 33. The air 41 purified in the cleaning chamber 33 is exhausted outdoors by the exhaust fan 39 via the filter unit 37. This filter portion 37 is for further removing moisture such as water droplets remaining in the air 41. In the present embodiment, the water 19 that has cleaned the contaminated exhaust 27 is always returned to the sewage recovery tank 31.

  The sewage dropped from the baffle plate 55 and returned to the sewage recovery tank 31 is adjusted in flow rate by the supply valve 73 by the sewage supply pump 71 and sent to the lower part of the electrolysis tank 69. The sewage rises between the electrode sets 81 (anode aluminum 77 and cathode stainless steel 79) and is separated into clean water 19 and solid matter by an oxidation / reduction action and an agglomeration action of aluminum hydroxide eluted from the anode. At that time, the side chain of an organic solvent such as toluene or xylene is oxidized by the oxidizing action on the anode side, and toluene and xylene are turned into harmless benzoic acid. Although benzoic acid is a weak acid, the pH in the liquid does not change because it is neutralized by aluminum ions (amphoterics) eluted from the anode. The above is fixed to the sludge 67 and aluminum hydroxide and discharged from the dirty water 19.

  Solid matter adhering to bubbles generated during electrolysis floats on the surface of the electrolytic cell as sludge 67. The sludge 67 that has floated is scraped off to the floating sludge collection tank 89 at regular intervals by a scraper 83 connected to the fluid pressure cylinder 85. The sludge 67 containing moisture is concentrated by removing moisture with a draining filter cloth 87.

  The purified electrolytic water becomes sludge removal water 99 from the position of the seventh minute from the upper side of the electrolytic cell 69, that is, directly above the electrode set 81, and contains a certain amount of aluminum hydroxide. And returned to the mixing water tank 21. The water surface adjustment plate 95 adjusts the electrolytic cell water surface that easily discharges floating sludge. While repeating the above, the polluted exhaust 27 continues to be purified.

  In the deodorizing apparatus 11 described above, the cleaning chamber 33 has a negative pressure with respect to the air supply chamber 23, the air supply chamber water surface 43 is near the lower edge of the drooping plate 47, and the contaminated exhaust 27 in the air supply chamber 23 causes the drooping plate 47 to Dive into the cleaning chamber 33. The contaminated exhaust gas 27 that has flowed in is mixed with the water 19 by the hoisting R plate 49 and mixed. The polluted exhaust 27 passes through the drooping plate 47 and collides with the winding R plate 49, and the water 19 is splashed. Fine particles and contaminated dust in the contaminated exhaust are caught by the water 19, and mixed and stirred with the fine particles and contaminated dust. It becomes a state. The contaminated exhaust 27 from which fine particles and contaminated dust have been removed moves up the cleaning chamber 33 from the hoisting R plate 49 and is exhausted from the exhaust port 35 in a state in which the odor is reduced.

  Thus, since the deodorizing apparatus 11 does not use thermal energy and does not use adsorbents such as activated carbon, there are few consumables, and the equipment can be simplified and the cost can be reduced. It also contributes to the reduction of

  Therefore, according to the deodorizing apparatus 11 according to the present embodiment, the contaminated exhaust 27 containing fine particles to which volatile organic compounds are attached and contaminated dust is washed with electrolyzed water mixed with aluminum hydroxide to obtain fine particles and pollutants. The sewage mixed with dust can be sent to the sewage electrolysis unit 15 to detoxify and remove fine particles, volatile organic compounds attached to the contaminated dust, etc. by oxidation / reduction action between the electrodes. As a result, heat energy is not used, and adsorbents such as activated carbon are not used, so there are few consumables, simplification and cost reduction of equipment can be realized, and both equipment cost and operation cost can be reduced. Also, carbon dioxide can be greatly reduced compared to the combustion method.
