Description

  The present invention relates to an exhaust deodorization apparatus and an exhaust deodorization method for a foul odor generating facility that deodorizes exhaust discharged outside from a barn or a garbage disposal facility.

  Exhaust gas generated from windowless barns that perform pig farming and poultry farming is characterized by a low odor concentration and a large air volume. In general, most of the deodorizers used to deodorize exhaust gas are for high-concentration and small amount of gas generated by composting equipment. Such deodorizers are used to deodorize a large amount of exhaust gas generated from barns. It is not suitable for use.

  On the other hand, the mixture of barns and ordinary houses tends to expand, and more than 60% of complaints caused by livestock are the generation of odors. For this reason, provision of the deodorizing apparatus which can deodorize a lot of exhaust_gas | exhaustion is desired.

  In view of this, an exhaust deodorization apparatus (in the literature, a biological deodorization apparatus) as described in Patent Document 1 has been proposed. As shown in FIG. 3 (cross-sectional view), the exhaust deodorization device 80 is provided in a windowless barn 70 and exhausts air containing bad odor in the barn, dust in exhaust exhausted from the ventilator 71, etc. And a deodorizing device 82 for deodorizing the exhaust gas supplied from the dust removing device 81 through a deodorizing material by using a coconut chip that has been added with organic substances and microorganisms as a deodorizing material.

  This conventional exhaust deodorization device is configured to deposit deodorizing material using coconut chip on a flat surface, and to supply exhaust gas supplied from the dust removal device to the deodorizing material from below the deodorizing material. Since it is necessary to deodorize a large amount of exhaust gas, the deodorizing material deposited in a flat shape has a large area. For this reason, the conventional exhaust deodorization apparatus has the problem that a large site is required.

  In addition, since the exhaust gas removed by the dust removing device is supplied to the deodorizing device through the pipe and flows through a plurality of air distribution pipes disposed below the deodorizing material, it is uniformly supplied to the planar deodorizing material. In addition, the conventional exhaust deodorization apparatus of the odor generating facility has a large ventilation resistance. For this reason, only the ventilation fan provided in the barn has a problem that the ventilation capacity is insufficient, replacement with a ventilation fan with a high ventilation capacity or addition of a new blower is required, and the conventional exhaust deodorization apparatus has a problem of high cost. .

  The present invention addresses such problems, and an object of the present invention is to provide an exhaust deodorization apparatus and exhaust deodorization method for a foul odor generating facility, which has a small installation area and a low cost.

  In order to solve such a problem, the present invention is an exhaust deodorization apparatus that deodorizes exhaust discharged outside from a malodor generating facility (for example, the windowless barn 70 in the embodiment), and is adjacent to the malodor generating facility. And a deodorizing chamber formed so as to cover the ventilating fan of the malodor generating facility, and a deodorizing material layer having a side surface facing the ventilating fan and arranged vertically in the deodorizing chamber.

By providing a deodorizing material layer, the installation area of a deodorizing material layer becomes small compared with the case where a deodorizing material layer is installed planarly, and the site area of the whole exhaust gas deodorizing apparatus can be made small. Further, since the deodorizing material layer is installed with the side surface facing the ventilation fan side, a large amount of exhaust gas sent from the ventilation fan can be supplied to the side surface as it is and passed through the deodorizing material layer. For this reason, piping which guides air from a ventilation fan to a deodorizing material layer becomes unnecessary, the pressure loss by piping etc. disappears, and the ventilation fan provided in the bad smell generation facility can be used as it is. As a result, it is not necessary to replace the ventilation fan with a high blowing capacity or to provide a new blower, and the cost of the deodorizing device can be reduced.

The exhaust gas can pass through the deodorizing material layer without staying in the deodorizing chamber. For this reason, efficient deodorization of exhaust gas can be performed.

  Further, the present invention is characterized in that a plurality of deodorizing material layers are provided adjacent to each other in the vertical direction.

  According to this invention, the deodorizing performance can be improved without enlarging the installation area of the deodorizing material layer by arranging the plurality of deodorizing material layers adjacent to each other in the vertical direction. In addition, by using a plurality of deodorizing material layers instead of a single one, it is possible to divide the deodorizing material layer having a height necessary for deodorizing a large amount of air sent from the ventilation fan. As a result, the height of each divided deodorizing material layer is reduced, and the degree to which the deodorizing material is reduced due to its own weight or secular change in each deodorizing material layer is suppressed, thereby suppressing a decrease in deodorizing performance. be able to.

  Further, in the present invention, the deodorizing material layer has a container-like storage portion (for example, the storage container 50 in the embodiment) having a large number of vent holes (for example, the mesh 51a in the embodiment) on at least the suction port side and the discharge port side. It is accommodated in the inside.

  According to this invention, the deodorizing material layer having a predetermined shape and a predetermined deodorizing performance can be obtained by storing the deodorizing material layer in a container-shaped storage unit having a large number of ventilation holes at least on the suction port side and the discharge port side. Layers can be easily formed.

  Moreover, the accommodating part of this invention has an opening part which can replenish a deodorizing material, It is characterized by the above-mentioned.

  According to this invention, when the deodorizing material layer accommodated in the accommodating portion is reduced by providing an opening capable of replenishing the deodorizing material in the accommodating portion, the deodorizing material can be easily reduced by replenishing the deodorizing material from the opening. It is possible to prevent the deterioration of the deodorizing performance.

  In addition, the present invention is characterized by providing a watering device (for example, the second watering device 60 in the embodiment) that supplies water to the deodorizing material layer so that the amount of moisture contained in the deodorizing material is within a predetermined range.

  According to this invention, by providing the watering device for supplying water to the deodorizing material layer, the malodorous component generated from the barn can be dissolved in the moisture in the coconut shell, adsorbed to the coconut shell, and temporarily held. For this reason, the decomposition | disassembly to the odorless component by the microorganisms in coconut husk can be made easy, and deodorizing performance can be improved.

  Further, the deodorizing chamber of the present invention is characterized by having a suction chamber that can receive the exhaust discharged from the ventilation fan and supply it to the deodorizing material layer.

  According to the present invention, by providing the deodorizing chamber with the suction chamber that can receive the exhaust discharged from the ventilation fan and supply it to the deodorizing material layer, the large amount of exhaust is sucked even when the flow rate of the exhaust is large. Once received in the chamber, it can be supplied to the deodorant layer. For this reason, it is possible to prevent a situation in which bad odors stay in the odor generating facility.

  In addition, the suction chamber of the present invention is characterized in that the exhaust discharged from the ventilation fan is airtightly received.

  According to the present invention, the suction chamber air-tightly receives the exhaust discharged from the ventilation fan, so that all of the exhaust gas containing bad odor discharged from the ventilation fan can be supplied to the deodorizing material layer. It is possible to reliably prevent a bad smell from leaking out.

  Furthermore, the present invention is characterized in that a dust removing device for removing dust and the like contained in the exhaust discharged from the ventilation fan is provided in the suction chamber.

For this reason, the dust in exhaust_gas | exhaustion supplied to a deodorizing material layer can be removed previously, the clogging of a deodorizing material layer can be prevented beforehand, and the long-term use of a deodorizing material layer can be enabled.

  Further, the present invention is an exhaust deodorization method for deodorizing exhaust exhausted from a malodor generating facility, wherein the deodorizing chamber is formed adjacent to the malodor generating facility so as to cover the ventilation fan of the malodor generating facility; And a deodorizing material layer vertically arranged in the deodorizing chamber with a side facing the ventilation fan side, and receiving exhaust exhausted from the odor generating facility in the deodorizing chamber and from the side of the deodorizing material layer It passes through the deodorizing material layer and is discharged out of the deodorizing chamber.

  According to the present invention, the exhaust gas discharged from the malodor generating facility is received in the deodorizing chamber disposed adjacent to the outside of the malodor generating facility, and the deodorizing material layer is disposed from the side surface of the deodorizing material layer disposed vertically. By exhausting it out of the deodorizing chamber through the inside, even if a large amount of exhaust is exhausted from the odor generating facility and received in the deodorizing chamber, the exhaust can be supplied to the side of the deodorizing material layer as it is. A large amount of exhaust gas can be deodorized. Therefore, piping for introducing air from the ventilation fan to the deodorizing material layer is not required, pressure loss due to the piping or the like is eliminated, and the ventilation fan provided in the odor generating facility can be used as it is. Moreover, it becomes unnecessary to replace with a ventilation fan with high ventilation capability, or to provide a new blower, and the cost of the deodorizing device can be reduced. In addition, compared with the case where the deodorizing material layer is installed in a plane, the deodorizing material layer of the present invention is arranged vertically, so the installation area of the deodorizing material layer is reduced, and the site area of the entire exhaust deodorizing device Can be reduced.

  According to the exhaust gas deodorization apparatus and the deodorization method of the malodor generating facility according to the present invention, the exhaust gas discharged from the malodor generating facility is received in a deodorizing chamber disposed adjacent to the outside of the malodor generating facility, and arranged vertically. By passing through the deodorizing material layer from the side surface of the deodorizing material layer and discharging it to the outside of the deodorizing chamber, the installation area of the exhaust deodorizing device can be reduced and the cost of the deodorizing device can be reduced.

  A preferred embodiment of an exhaust deodorization apparatus and a deodorization method for a malodor generating facility according to the present invention will be described below with reference to FIGS. In this embodiment, a windowless barn where pigs are raised as an odor generating facility is taken as an example, and an exhaust deodorizing apparatus and a deodorizing method in the case of deodorizing exhaust discharged from the windowless barn will be described. First, before explaining the exhaust deodorization method according to the present invention, an exhaust deodorization apparatus using this method will be explained.

  As shown in FIG. 1 (cross-sectional view), the exhaust deodorization apparatus 1 includes a deodorization chamber 10 installed adjacent to the outside of the windowless barn 70, and exhaust exhausted from a ventilation fan 71 disposed in the deodorization chamber 10. And a deodorizing material layer 40 for deodorizing the exhaust gas.

  A large number of pigs P are raised in the windowless barn 70. The ventilation fan 71 described above is attached to the side wall 72 of the barn on one side of the windowless barn 70, and the air in the windowless barn 70 is discharged by the ventilation fan 71. The windowless barn 70 may be used for raising chickens, for example.

  The deodorizing chamber 10 is provided adjacent to the barn side wall 72 of the windowless barn 70, and is erected so as to surround the floor plate part 11 laid on the lower outer side of the barn side wall 72 and the peripheral part of the floor plate part 11. It has a side wall part 12 and a top plate part 14 that covers the upper opening part 13 formed by being surrounded by the side wall part 12 and the barn side wall 72, and is constituted by the floor board part 11, the side wall part 12, and the top plate part 14. It is formed so as to cover the ventilation fan 71.

  The deodorizing chamber 10 includes a suction chamber 17 provided on the barn side and an exhaust chamber 18 provided on the side away from the windowless barn 70. The barn side of the suction chamber 17 is partitioned by a barn side wall 71, and the exhaust chamber side of the suction chamber 17 is partitioned by a partition plate 19 that separates the suction chamber 17 and the exhaust chamber 18. An air circulation hole 20 that is opened in two upper and lower stages is provided in an intermediate portion of the partition plate 19. A deodorizing material layer 40 is installed on the outside of each air circulation hole 20. The deodorizing material layer 40 is installed such that the side 40a on the barn side faces the ventilation fan side. In the drawing, the side 40a on the barn side is arranged so as to face the ventilation fan 71, but the present invention is not limited to this, and the side 40a may be inclined with respect to the exhaust direction of the ventilation fan 71.

  The suction chamber 17 is configured so that the exhaust discharged from the ventilation fan 71 can be received in an airtight manner. For this reason, all the exhaust from the ventilation fan 71 can be supplied to the deodorizing material layers 40, 40, and the possibility that exhaust containing bad odor leaks out of the windowless barn 70 is surely prevented. The exhaust chamber 18 has an exhaust port 12a in the side wall portion 12 on the rear side, and the exhaust gas that has been dedusted and deodorized is exhausted from the exhaust port 12a.

  A dust removing device 30 is provided in the suction chamber 17. The dust removing device 30 is disposed opposite to the ventilation fan 71 and extends in the vertical direction and has a large number of ventilation holes. The dust removal device 30 is disposed closer to the ventilation fan than the dust removal main body 31, and the side surface of the dust removal main body 31 is substantially uniform. A first watering device 32 that sprays water and a water storage tank 33 provided at a position below the dust removing main body 31.

  The first watering device 32 includes a pump 34 installed in the water storage tank 33, and an ejection pipe that is connected to the pump 34 and is erected on the ventilation fan side of the dust removing main body 31 to flow water supplied from the pump 34 upward. 35 and a plurality of spray nozzles 36 sprayed toward the dust removing main body 31 with water flowing through the jet pipe 35 disposed at a predetermined interval downward from the tip of the jet pipe 35. The The water sprayed from the spray nozzle 36 pushes the dust captured by the dust removing main body 31 downward, drops it into the water storage tank 33, precipitates it, and is sucked again by the pump 34 and used for water spraying. Since the water supplied to the dust removing main body 31 is lost due to evaporation or the like and the amount of water stored in the water storage tank 33 gradually decreases, the water storage tank 33 is provided with a replenishing device (not shown) capable of replenishing water. It has been. The dust removing device 30 is not limited to the above-described configuration as long as dust-removed air can be supplied to the deodorizing material layer 40.

  The deodorizing material layer 40 is a container 50 in which an organic substance and microorganisms are added to a non-heat-treated coconut chip obtained by crushing coconut shells to about 10 to 15 mm, and the deodorizing material prepared to have a moisture content of about 60 to 95% extends in the vertical direction. It is arranged in a stacked state inside. That is, the deodorizing material layer 40 is arranged in a state extending in the vertical direction.

  As shown in FIG. 2 (perspective view), the storage container 50 has a rectangular parallelepiped shape, and includes a wall surface 51 having a mesh 51a on the entire surface to facilitate the circulation of exhaust gas. The container 50 has a width dimension B of about 50 cm and a height dimension H of about 50 cm to about 200 cm, for example. An opening 52 is formed at the rear upper end of the storage container 50, and coconut chip as a deodorizing material can be supplied through the opening 52. Note that the opening 52 may be provided on the top wall surface 51 of the container 50.

  As shown in FIG. 1, the storage container 50 is attached in a state of being placed on the end of the air circulation hole 20 on the exhaust chamber side. Above the storage container 50, a second water sprinkler 60 that sprays water on the deodorizing material layer 40 stored in the storage container 50 is provided. The second water sprinkler 60 is connected to the water storage tank 61 provided at the lower part of the exhaust chamber 18 and behind the deodorizing material layer 40, the pump 62 installed in the water storage tank 61, and the pump 62. A jet pipe 63 which is erected on the rear side of the deodorizing material layer 40 and flows the water supplied from the pump 62 upward, and a spray nozzle 64 which sprays from the tip of the jet pipe 63 toward the deodorizing material layer 40. It is configured.

  The jet pipe 63 branches in the middle to become two branch pipes 63a and 63b. One branch pipe 63a extends to a position above the deodorizing material layer 40 disposed on the lower side, and the other branch pipe 63b is on the upper side. It extends to the upper position of the deodorizing material layer 40 arranged in the above. The above-described spray nozzle 64 is attached to the tip of each branch pipe 63a, 63b. While the water sprayed from the spray nozzle 64 is supplied to the deodorizing material layer 40, the excess water passes through the deodorizing material layer 40 and is returned to the water storage tank 61 to be temporarily stored, and again sucked by the pump 62 and circulated. Then, it flows through the spray pipe 63 and is sprayed from the spray nozzle 64. For this reason, the water sprayed on the deodorizing material layer 40 is not discharged out of the water storage tank 61. In addition, since the water supplied to the deodorizing material layer 40 is lost due to evaporation or the like, and the amount of water stored in the water storage tank 61 gradually decreases, the water supply to the water storage tank 61 is not shown. Is provided.

  Next, an exhaust deodorization method using the exhaust deodorization apparatus 1 and results will be described.

  The air containing bad odor and dust generated in the windowless barn 70 is discharged into the suction chamber 17 of the exhaust deodorizer 1 by the ventilation fan 71. The exhaust discharged from the ventilation fan 71 flows through the suction chamber 17 and is sent to the dust removing device 30. In the dust removing main body 31 of the dust removing device 30, the dust sprayed by the water sprayed from the first water sprinkler 32 is adsorbed and dropped into the water in the water storage tank 33. When the water in the water storage tank 33 is reduced, new water is supplied by the supply device.

  On the other hand, the odor component that has been dedusted and remains in the exhaust gas passes through the dust removing main body 31, flows through the exhaust chamber side of the suction chamber 17, and is sent to the deodorizing material layer 40. Here, since the suction chamber 17 is configured to be airtight, there is no possibility that exhaust gas containing bad odor that has passed through the dust removing main body portion 31 leaks out from the suction chamber 17.

  The exhaust gas containing bad odor sent to the deodorizing material layer 40 passes through the mesh 51a of the wall surface 51 of the container 50 shown in FIG. 2 and passes through the deodorizing material layer 40 of the coconut chip to the coconut chip that is the deodorizing material. The odorous component in the exhaust gas is decomposed into odorless components by the microorganisms in the deodorizing material, and then deodorized after being once held on the deodorizing material by adsorption of the odorant. The deodorizing material layer 40 is sprinkled from the watering nozzle 64 of the second watering device 60, and the excess water that has passed through the deodorizing material layer 40 of the coconut chip is returned to the water storage tank 61 and temporarily stored. Circulated by pump 62. For this reason, the water sprayed to the deodorizing material layer 40 is not discharged | emitted from the water storage tank 61 outside. The deodorized exhaust gas flows in the exhaust chamber 18 and is discharged outside through the exhaust port 12a.

  In this way, the deodorizing material layer 40 is formed by laminating deodorizing materials mainly composed of non-heat-treated coconut chip with the addition of organic matter and microorganisms, and extending in the vertical direction. The deodorizing material layer 40 is installed as compared with the case where the deodorizing material layer 40 is installed in a plane because the exhaust gas is sucked from the side surface 40a and deodorized and discharged from the other side surface. The area can be reduced, and the site area for installing the exhaust deodorization apparatus 1 can be reduced. Further, since the deodorizing material layer 40 mainly composed of coconut chip has good air permeability and is arranged to extend in the vertical direction, a large amount of exhaust discharged from the ventilation fan 71 can be directly sucked through and exhausted. A pipe for leading the exhaust gas from 71 to the deodorizing material layer 40 becomes unnecessary, and pressure loss due to the pipe or the like is eliminated, and the ventilation fan 71 provided in the windowless barn 70 can be used as it is. As a result, it is not necessary to replace the ventilation fan 71 with a ventilation fan having a high blowing capacity or to provide a new blower, and the cost of the exhaust deodorizing apparatus 1 can be reduced.

  Moreover, since the deodorizing material layer 40 is installed adjacent to each other in the vertical direction, the deodorizing performance can be improved without increasing the installation area of the deodorizing material layer 40. Moreover, by using a plurality of deodorizing material layers 40 instead of a single one, it is possible to divide the deodorizing material layer having a height necessary for deodorizing a large amount of exhaust gas discharged from the ventilation fan 71. As a result, the height dimension of each deodorized material layer 40 can be reduced, and the degree of deodorizing material being reduced due to its own weight or secular change of the coconut chip constituting each deodorized material layer 40 can be suppressed. A decrease in performance can be suppressed.

Here, the air volume of the exhaust gas sent to the deodorizing material layer 40 is set to 5.5 m ³ / min per unit area (apparent air speed in the suction chamber 17 is 100 mm / sec), and the contact time of the exhaust gas passing through the deodorizing material layer 40 is Table 1 shows the results of deodorization when the water spray amount to the deodorizing material layer 40 is about 100 L / (m ² · day) for 5 seconds. As shown in Table 1, the concentration of (NH ₃ ) contained in the exhaust discharged from the windowless barn 70 is an average of 25 ppm, the concentration of ammonia discharged from the dust removing device 30 is an average of 19 ppm, and from the deodorizing material layer 40 The concentration of ammonia discharged was an average of 0.1 ppm, and a high deodorizing effect was obtained. In addition, sulfur compounds and organic compounds such as amines also showed a high deodorizing effect. For this reason, almost all of the odor components of the exhaust discharged from the windowless barn 70 could be deodorized.

  As a result of investigating the deodorization performance in the exhaust deodorization apparatus 1 installed adjacent to the windowless barn 70 as described above, a good deodorization performance could be obtained.

  In the above-described embodiment, the example in which the deodorizing material layer 40 is arranged in the substantially vertical direction is shown. However, the deodorizing material layer 40 may be arranged obliquely so as to incline toward the suction chamber 17 as it goes upward. . In this case, if a plurality of openings 52 provided in the storage container 50 for storing the deodorizing material layer 40 are arranged on the rear wall surface 51 with a predetermined interval in the vertical direction, replenishment of palm rose chips as a deodorizing material is provided. Can be made easier. Moreover, in the Example mentioned above, although exhaust_gas | exhaustion containing the malodor discharged from the windowless barn 70 was made into the process target, it is good also considering the air containing the malodor generated from garbage as a process target.
