Description

  The present invention relates to a rotary biological deodorization apparatus.

  In recent years, odor complaints from small and medium-sized businesses and livestock industries close to the living environment have increased, and the sources of odor causing complaints tend to diversify. Among them, the volatile organic compound (VOC) contained in the gas discharged from a printing / painting factory or the like not only causes bad odor, but is also a causative substance such as suspended particulate matter (SPM) and photochemical oxidant. For this reason, measures for reducing VOC emissions at individual offices are required. In 2006, the Air Pollution Control Act was amended to set VOC emission standards for large-scale facilities.

  As a method for deodorizing bad odors, a method using microorganisms is attracting attention because of its low cost and low environmental impact. This deodorizing method using microorganisms is considered to be effective for removing malodor derived from VOC, and various deodorizing treatment methods and apparatuses have been proposed. For example, a method using activated carbon having a specific water content and specific surface area as a carrier for supporting microorganisms (for example, Patent Document 1), and a plurality of carriers having different particle diameters, shapes, or surface properties as carriers for supporting microorganisms. A method (for example, Patent Document 2) is proposed. In addition, the carrier is divided into a part that performs deodorization and a part that supplies and cleans nutrients, and a biological deodorization device that performs deodorization and cleaning in parallel (for example, Patent Document 3). A method (for example, Patent Document 4) in which VOCs are stripped into a gas and then treated with microorganisms has been proposed.

  In addition, the inside of the rotating cylindrical drum is divided into a plurality of partitions with a partition wall, and a basic configuration in which each of the divided and partitioned portions is filled with a deodorizing treatment carrier so that the processing gas can pass inward and outward, and inside Two cylindrical drums arranged at the top and bottom filled with a deodorizing treatment carrier, a casing configured to rotatably store the cylindrical drum, and a nutrient agent disposed in the casing and disposed in the deodorizing treatment carrier in the cylindrical drum And a watering nozzle that sprays an aqueous sodium hydroxide solution (for example, Patent Document 5).

  Next, the configuration of the biological deodorization apparatus of the present invention will be described with reference to FIGS. FIG. 1 is a partial cross-sectional configuration diagram showing a schematic configuration of a biological deodorization apparatus according to an embodiment of the present invention, FIG. 2 is a side sectional view of the biological deodorization apparatus taken along line AA in FIG. 1, and FIG. FIG. 4 is a side cross-sectional view showing the behavior of the deodorizing carrier in the carrier filling portion in a configuration having no flap. However, the present invention is not limited to the following examples.

  A rotating body 10 and a water tank 100 are arranged in the casing 1. The rotating body 10 basically includes an inner cylinder 11 having a through hole 12, an outer cylinder 13 having a through hole 14, a plurality of partition plates 16 a to 16 f and a side plate 15 between the inner cylinder 11 and the outer cylinder 13. is doing. The inner cylinder 11 and the outer cylinder 13 are connected and fixed by the partition plates 16 a to 16 f, and the side plate 15 is fixed to the side of the inner cylinder 11 and the outer cylinder 13. The inner cylinder 11 and the outer cylinder 13 may be connected and fixed by the side plate 15.

  Further, a hinge 18 is provided on each of the plurality of partition plates 16a to 16f, the hinge 18 is used as a rotation fulcrum (fixed end), and flaps 17a to 17L that are rotatable at a predetermined angle with the opposite side as a free end are provided. Yes. The end portions of the flaps 17a to 17L on the side plate 15 side are in contact with or close to the inner surface of the side plate 15, and the end portions of the flaps 17a to 17L on the outer tube 13 side are in contact with or close to the inner surface of the outer tube 13. And slidable.

  In FIG. 3, the flaps 17a to 17L are provided with a sealing material. It is preferable that the sealing material 200 is fixed to the end portions of the flaps 17a to 17L in the direction of the side plate 15 so that the sealing material 200 contacts the inner surface of the side plate 15 and is slidable. As a result, the seal between the flaps 17a to 17L and the inner surface of the side plate 15 can be made more reliable, and leakage of the gas to be processed (short path of the gas to be processed) can be prevented. Further, it is possible to prevent the deodorizing carrier from being entangled with the end portions of the flaps 17a to 17L in the direction of the side plate 15 and entering the gap. Therefore, the flaps 17a to 17L can always be smoothly rotated.

  Moreover, it is preferable that the sealing material 201 is fixed to the end of the flaps 17 a to 17 L on the outer cylinder 13 side, and the sealing material 201 is configured to be slidable on the inner surface of the outer cylinder 13. In this case, the flaps 17a to 17L can be rotated more smoothly. The sealing materials 200 and 201 may be rubber materials, resin materials, or the like, but preferably have predetermined elasticity. Further, it is preferable that the hinge 18 part also prevents leakage of the gas to be processed (short path of the gas to be processed) by the structure of the hinge 18 itself or the sealing material.

  Further, the flaps 17a to 17L are provided so that the free end side is rotatable by a predetermined angle. The hinges 18 of the flaps 17a to 17L are set to have a radius of curvature from the rotation fulcrum to the inner surface of the outer cylinder 13, and the flaps 17a to 17L. The curvature radius of the inner surface of the outer cylinder 13 on which the free end side slides is configured to be substantially the same. A portion indicated by L in FIG. 2 indicates the length of an arc portion in which the radius of curvature of the inner surface of the outer cylinder 13 on which the free ends of the flaps 17a to 17L slide is substantially the same. A portion indicated by L in FIG. 2 is set to be at least the rotation range of the flaps 17a to 17L with the partition plates 16a to 16f interposed therebetween. In addition, what is necessary is just to let the outer cylinder 13 other than the part described by L in FIG. 2 be a linear form or the curvature radius from the center of the inner cylinder 11. FIG.

  As a result, when the weights 19a to 19L fixed to the flaps 17a to 17L are rotated in a direction away from the partition plates 16a to 16f, the end of the flaps 17a to 17L on the outer tube 13 side and the outer tube caused by the difference in curvature radius It is possible to prevent the gap with the inner surface of 13 from being enlarged. That is, even if the flaps 17a to 17L rotate within the range indicated by L in FIG. 2, the gap between the end of the flaps 17a to 17L on the outer cylinder 13 side and the inner surface of the outer cylinder 13 can be made constant. it can.

  On the other hand, when the gap (separation distance) between the end of the flaps 17a to 17L on the outer cylinder 13 side and the inner surface of the outer cylinder 13 is increased, the flaps 17a to 17L are repeatedly rotated in the process. The deodorizing carrier filled in the end portion on the outer cylinder 13 side of 17a to 17L is entangled, or enters the enlarged gap between the end portion on the outer cylinder 13 side of the flap 17a to 17L and the inner surface of the outer cylinder 13, and the flap The smooth rotation of 17a-17L will be inhibited remarkably.

  In the above-described embodiment, when the flaps 17a to 17L are rotated, the gap between the end portions of the flaps 17a to 17L and the inner surface of the outer cylinder 13 can be made constant. That is, the rotation trajectory of the end portion on the free end side of the flaps 17 a to 17 L can always be along the inner surface of the outer cylinder 13. Therefore, it is possible to prevent the deodorizing carrier from getting entangled with the end portions of the flaps 17a to 17L on the outer cylinder 13 side, or entering and leaving the gap of the deodorizing carrier. Further, when the sealing material 201 is fixed, the sealing material 201 always contacts the inner surface of the outer cylinder 13 evenly, and leakage of the gas to be processed (short path of the gas to be processed) can be further prevented. Further, the flaps 17a to 17L can always be smoothly rotated.

  Further, a protrusion 13 a (stopper means) is provided on the inner surface of the outer cylinder 13. The protrusion 13a restricts the flaps 17a to 17L to rotate within a range indicated by L in FIG. The free ends of the flaps 17a to 17L come into contact with the protrusion 13a, and the flaps 17a to 17L are controlled to rotate within the range indicated by L in FIG. Thereby, the rotation of the flaps more than necessary can be restricted, and the flaps can be prevented from contacting each other. Furthermore, it is possible to prevent the deodorizing carrier from being excessively compressed.

  The protrusion 13a is formed integrally with the outer cylinder 13 by indenting a part of the outer cylinder 13 of each of the plurality of carrier filling portions 20a to 20f. Further, the protrusion may be provided, and the hinge 18 itself may be configured to restrict the rotation range.

  Weights (flap rotation urging means) 19a to 19L having a predetermined mass are fixed to the partition plates 16a to 16f side of the flaps 17a to 17L and to the outer cylinder 13 side (free end side). The flaps 17a to 17L receive a force component in the direction of gravity by the weights 19a to 19L, and are urged to rotate with the hinge 18 as a rotation fulcrum (fixed end).

  Although the flaps 17a to 17L rotate only with the mass of the flaps 17a to 17L, when the weights 19a to 19L are fixed, the direction of the flaps 17a to 17L depends on the resistance on the sliding surfaces of the side plates 15 and the outer cylinder 13. And can be rotated smoothly. The masses 19a to 19L may be set based on the rotation range, the resistance on the sliding surface, the necessary pressing force of the deodorizing carrier, and the like. Each of the weights 19a to 19L may be divided into one or a plurality.

  The cross-sectional shape surrounded by the inner cylinder 11, the outer cylinder 13, the partition plates 16a to 16f, the side plate 15 and the flaps 17a to 17L constitutes a plurality of fan-shaped carrier filling portions 20a to 20f.

  In addition, although the position of the hinge 18 which is a rotation fulcrum (fixed end) of the flaps 17a to 17L may be provided in the inner cylinder 11, by providing it in the partition plates 16a to 16f, the configuration can be simplified and the inner cylinder 11 is preferable because the ejection resistance of the gas to be processed from the 11 through holes 12 can be reduced. Moreover, it is preferable to provide the hinge 18 in the position to the half of the length from the inner cylinder 11 to the outer cylinder 13 of the partition plates 16a-16f.

  Next, the operation | movement operation | movement and effect | action of the biological deodorizing apparatus of this invention are demonstrated. Water (liquid) 101 is poured into the water tank 100, the carrier filling portions 20a to 20f are filled with a deodorizing carrier, and the gas discharged into the inner cylinder 11 from the malodor generating facility through the duct 54 by the blower 53. A gas to be treated is introduced, and the rotating body 10 is rotated in the circumferential direction by a belt 51 and a motor 52 which are rotation driving means. The deodorizing carrier is filled or removed by providing an opening and a lid (not shown) in a part of the outer cylinder 13 or the side plate 15.

  As shown in FIG. 2, the gas to be treated supplied into the inner cylinder 11 via the duct 54 passes through the through-hole 12 of the inner cylinder 11 in the direction of the arrow and is introduced into the carrier filling portions 20a to 20f. Then, it flows in the direction of the arrow, passes through the through hole 14 of the outer cylinder 13, and is discharged to the outside of the rotating body 10. While passing through the deodorizing carrier in the carrier filling portions 20a to 20f, the malodor-causing substance in the gas to be treated can be adsorbed on the deodorizing carrier and / or decomposed into microorganisms and deodorized.

  In the rotation position of the rotating body 10 shown in FIG. 2, the carrier filling portion 20a positioned directly above has the flaps 17a and 17b urged by the weights 19a and 19b, and the weights 19a and 19b come into contact with the partition plates 16a and 16b. The flaps 17a and 17b are also turned to the partition plates 16a and 16b with the hinge 18 as a pivot.

  The deodorizing carrier filled in the carrier filling portion 20a comes into contact with the inner cylinder 11 side by its own weight, forms a predetermined space on the outer cylinder 13 side, and has an upper surface substantially horizontal. Therefore, the gas to be treated that has flowed into the carrier filling portion 20a from the plurality of through holes 12 of the inner cylinder 11 flows uniformly between the filled deodorizing carriers and is discharged from the plurality of through holes 14 of the outer cylinder 13. The

  The carrier filling portion 20b located diagonally above (right diagonally upward in FIG. 2) is brought into contact with the partition plate 16c by the weight 19d of the flap 17d, and by the weight 19c of the flap 17c. The weight 19d is separated from the partition plate 16b, and the flap 17c is rotated to the flap 17d side (partition plate 16c side) using the hinge 18 as a rotation fulcrum. Moreover, the free end side of the flap 17c is in contact with the protrusion 13a, and the rotation range is restricted.

At this time, the deodorizing carrier filled in the carrier filling portion 20b is moved and stirred in the carrier filling portion 20b as the flap 17c rotates, and is brought into contact with the outer cylinder 13 side, so that the state of the carrier filling portion 20a is reached. Does not form such a space. Further, a predetermined pressure acts on each of the deodorizing carriers.
Therefore, the gas to be treated that has flowed into the carrier filling portion 20b from the plurality of through holes 12 of the inner cylinder 11 flows uniformly between the filled deodorizing carriers and is discharged from the plurality of through holes 14 of the outer cylinder 13. The

  Further, in the carrier filling portion 20c located diagonally below (right diagonally downward in FIG. 2), the weight 19f comes into contact with the partition plate 16d by the biasing force of the weight 19f of the flap 17f, and the weight 19e of the flap 17e is attached. Due to the force, the weight 19e is separated from the partition plate 16b, and the flap 17e is rotated to the flap 17f side (partition plate 16d side) using the hinge 18 as a rotation fulcrum. Moreover, the free end side of the flap 17e is in contact with the protrusion 13a and the rotation range is restricted.

  At this time, the deodorizing carrier filled in the carrier filling part 20c is moved and stirred in the carrier filling part 20c as the flap 17e rotates, and is brought into contact with the outer cylinder 13 side, so that the state of the carrier filling part 20a is reached. Does not form such a space. Further, a predetermined pressure acts on each of the deodorizing carriers. Therefore, the gas to be treated that has flowed into the carrier filling portion 20 c from the plurality of through holes 12 of the inner cylinder 11 flows uniformly between the filled deodorizing carriers and is discharged from the plurality of through holes 14 of the outer cylinder 13. The

  The carrier filling portion 20d located directly below the weight 19g is separated from the partition plate 16d by the bias of the weight 19g of the flap 17g, and the flap 17g has a flap 17h side (partition plate 16e side) with the hinge 18 as a rotation fulcrum. And the weight 19h of the flap 17h is separated from the partition plate 16e, and the flap 17h rotates to the flap 17g side (partition plate 16d side) using the hinge 18 as a pivot point. It has become a state. Each of the rotation ranges of the flap 17g and the flap 17h is substantially half of the rotation range of the flap 17e of the carrier filling portion 20c located obliquely below (right obliquely downward in FIG. 2). Further, the rotation range of the free ends of the flaps 17g and 17h is restricted by the protrusion 13a.

  At this time, the deodorizing carrier filled in the carrier filling portion 20d is moved and stirred in the carrier filling portion 20d as the flaps 17g and 17h rotate, and contacts the outer cylinder 13 by its own weight. Thus, a space is formed in the inner cylinder 11 of the carrier filling portion 20d. In addition, a predetermined pressure acts on each of the deodorizing carriers. Therefore, the gas to be treated which has flowed into the carrier filling portion 20d from the plurality of through holes 12 of the inner cylinder 11 flows uniformly between the filled deodorizing carriers, and is discharged from the plurality of through holes 14 of the outer cylinder 13. The

  At this time, the lower end portion of the carrier filling portion 20d located immediately below is immersed in the liquid 101 in the water tank 100, and the liquid 101 enters the deodorizing carrier moved to the outer cylinder 13 side through the through hole 14 and is wet. It will be in the state. In addition, the magnitude | size of the water tank 100 can be suitably set according to the magnitude | size of a rotary body. As a material of the water tank 100, for example, aluminum, iron, stainless steel, or the like can be used.

  Furthermore, the water tank 100 may include, for example, at least one of a nutrient source supply unit, a temperature adjustment unit, and a sterilization unit. The nutrient source supply means is a means for adding a substance serving as a nutrient for maintaining and / or improving the activity of microorganisms to the water tank 100, and includes, for example, a nutrient substance storage tank and a pump for feeding the nutrient substance. The The temperature adjusting means is a means for adjusting the temperature of the liquid in the water tank to a temperature optimal for the activity of the microorganism, and examples thereof include a heating means such as a heater. The sterilizing means is, for example, a means for suppressing the propagation of microorganisms in the water tank and maintaining the quality of the liquid suspension in the water tank, and includes an ultraviolet lamp. Furthermore, you may provide the isolation | separation means of a surplus cell.

  In addition, since the deodorizing treatment can be performed while immersing a part of the deodorizing carrier in the liquid, for example, blockage and clogging of the carrier can be reduced, and the deodorizing efficiency can be improved. Since a part of the deodorizing carrier filled in the rotating body is immersed in the liquid in the water tank periodically and / or intermittently during the deodorizing treatment, for example, blockage and clogging of the carrier can be reduced. For this reason, for example, high deodorization efficiency can be maintained for a long period of time, and maintenance and running costs can be reduced.

  Further, in the carrier filling portion 20e located diagonally below (left diagonally downward in FIG. 2), the weight 19i comes into contact with the partition plate 16e by the urging force of the weight 19i of the flap 17i, and the weight 19j of the flap 17j is attached. Due to the force, the weight 19j is separated from the partition plate 16f, and the flap 17j is rotated to the flap 17i side (partition plate 16e side) with the hinge 18 as a rotation fulcrum. Moreover, the free end side of the flap 17j is in contact with the protrusion 13a and the rotation range is restricted.

At this time, the deodorizing carrier filled in the carrier filling portion 20e is moved and agitated in the carrier filling portion 20e as the flap 17j rotates, comes into contact with the outer cylinder 13 side, and is in the state of the carrier filling portion 20a. Does not form such a space. Further, a predetermined pressure acts on each of the deodorizing carriers.
Therefore, the gas to be treated that has flowed into the carrier filling portion 20 e from the plurality of through holes 12 of the inner cylinder 11 flows uniformly between the filled deodorizing carriers, and is discharged from the plurality of through holes 14 of the outer cylinder 13. The

  The carrier filling portion 20f located obliquely above (left obliquely upward in FIG. 2) has the weight 19k in contact with the partition plate 16f by the bias of the weight 19k of the flap 17k, and the bias of the weight 19L of the flap 17L. The weight 19L is separated from the partition plate 16a, and the flap 17L is rotated to the flap 17k side (partition plate 16f side) using the hinge 18 as a rotation fulcrum. Moreover, the free end side of the flap 17L is in contact with the protrusion 13a and the rotation range is restricted.

  At this time, the deodorizing carrier filled in the carrier filling portion 20f is moved and stirred in the carrier filling portion 20f as the flap 17L is rotated, and is brought into contact with the outer cylinder 13 side so as to be in the state of the carrier filling portion 20a. Does not form such a space. Further, a predetermined pressure acts on each of the deodorizing carriers. Accordingly, the gas to be treated that has flowed into the carrier filling portion 20f from the plurality of through holes 12 of the inner cylinder 11 flows uniformly between the filled deodorizing carriers, and is discharged from the plurality of through holes 14 of the outer cylinder 13. The

  2 shows the state of the carrier filling portions 20a to 20f at the rotational position of the rotating body 10. However, as the rotating body 10 rotates, each of the carrier filling portions 20a to 20f has a single rotating body 10. The above-described state is repeated every time it rotates.

  FIG. 4 is a side cross-sectional view showing the behavior of the deodorizing carrier in the carrier filling portion in the conventional structure having no flap. The state of the carrier filling part 20b located diagonally above (right diagonally upward in FIG. 4) is that the deodorizing carrier filled in the carrier filling part 20b moves by its own weight and forms a space 300 above the carrier filling part 20b. The upper surface of the deodorizing carrier that is formed is substantially horizontal.

  In this state, as shown by the arrow A of the carrier filling portion 20b in FIG. 4, the gas to be treated that has flowed into the carrier filling portion 20b from the plurality of through holes 12 of the inner cylinder 11 is close to the space 300 and has a resistance. A large amount flows to the side of the partition plate 16b of the deodorizing carrier. On the other hand, as shown by an arrow B, the amount of gas to be processed decreases on the side of the partition plate 16c having a high resistance where the deodorizing carrier is in contact with the outer cylinder 13.

  Further, the state of the carrier filling portion 20c located obliquely below (right obliquely downward in FIG. 4) is that the deodorizing carrier filled in the carrier filling portion 20c is moved by its own weight and is spaced above the inside of the carrier filling portion 20c. 300 and the top surface of the deodorizing carrier is substantially horizontal.

As shown by the arrow B, the amount of the gas to be treated flows extremely decreases on the side of the partition plate 16d having a high resistance where the deodorizing carrier is in contact with the outer cylinder 13.

  As described above, in the conventional configuration having no flap shown in FIG. 4, the gas to be treated that flows into the carrier filling portion from the plurality of through holes 12 of the inner cylinder 11 flows evenly distributed between the filled deodorizing carriers. Instead, it is discharged from the plurality of through holes 14 of the outer cylinder 13. Therefore, the distribution distribution of the deodorizing carriers inside each divided carrier filling portion is biased, and the ventilation resistance of the gas to be treated of the deodorizing carriers becomes extremely uneven. For this reason, the contact of the gas to be treated with the carrier for deodorization is uneven and has a large variation, the deodorization treatment is unstable, and the efficiency of the deodorization treatment is poor.
