Air is concentrated and supplied to the extraction side (mature organic waste side) where the passage resistance of organic waste is low, and not sufficiently supplied to the input side (immature organic waste side) It was.

  In order to solve this problem, a composting facility has been proposed in which the amount of air supplied to the air pipe can be adjusted according to the progress of fermentation of organic waste (for example, see Patent Document 1).

Japanese Patent No. 3443055

  However, in the composting facility described above, no consideration is given to the air supply amount at the proximal end portion of the air pipe and the air supply amount at the distal end portion. Therefore, if there is a large difference between the air supply amount at the proximal end side and the air supply amount at the distal end side in one air pipe, there will be a difference in the aging of composted organic waste. Become. This difference in aging has made it difficult to homogenize compost (composted organic waste).

  In order to solve the above-described problems and achieve the object, the present invention provides a blower, a header pipe connected to the blower, a plurality of air supply pipes connected to the header pipe, and the air supply pipes disposed at the bottom. An air flow generated by the blower is distributed to the plurality of air supply pipes by the header pipe, and the organic waste accumulated in the fermenter is formed from a jet formed in each of the air supply pipes. In a composting facility that supplies and promotes fermentation of organic waste, a loop pipe that connects ends of the plurality of air pipes to each other is provided to allow air to flow.

  The composting facility according to the present invention is provided with a loop pipe connecting the ends of a plurality of air supply pipes to each other, enabling air circulation, and thus reducing the difference in the air supply amount between the plurality of air supply pipes, It is possible to reduce a difference in air supply amount between the proximal end portion and the distal end portion of each air supply pipe. For this reason, the difference in the ripening condition of composted organic waste can be reduced, and there is an effect that uniform compost can be provided.

The fermentation tank 33 for primary fermentation or the like according to the present embodiment has a width of about 5 meters, a depth of about 10 meters, and a partition wall height of about 3 meters. In the fermenter 33, organic waste can be deposited up to a height of about 2 meters in general and about 2.5 meters at the maximum.

  The bottom wall 331 is formed with a groove for header pipe (not shown), a groove for air supply pipe 3312, and a groove for loop pipe (not shown). The groove for header pipe is formed along the back wall 332, and a plurality of grooves for air supply pipe 3312 are formed so as to extend in a comb-tooth shape from the groove for header pipe toward the carry-in port. is there. These air channel concave grooves 3312 are evenly spaced, and are sufficiently far from the fermenter 33 (at a position where the organic waste D is deposited) so as to intersect with these air channel concave grooves 3312. The groove for the loop tube is formed at the position). Therefore, even when the organic waste D is carried out by the wheel loader, the claw of the wheel loader bucket does not interfere with the groove for the loop pipe. In addition, each fermenter 33 of the primary fermentation building 3 is formed with six grooves 3312 for the air supply pipe at intervals of 1 meter or less.

  An air blower 35 is installed in the passage soil 34 between the fermenters 33 on the side opposite to the side on which the organic waste is deposited. A header pipe 36 accommodated in the groove for header pipe is connected to the blower 35 so that an air flow generated by the blower 35 can be supplied to the header pipe 36.

The drainage holes are for discharging moisture that has flowed out due to the compaction of the accumulated organic waste D into the groove for the air pipe, and are formed in each air pipe 37 by two. A loop pipe 38 accommodated in a groove for loop pipe is connected to the end of each air supply pipe 37. The loop pipe 38 has the same diameter as the air supply pipe 37, communicates with the air supply pipe 37, and allows air to flow between the air supply pipes 37. Therefore, the difference in the air supply amount between the air supply pipes 37 can be reduced, and the difference in the air supply amount between the proximal end part (header pipe side) and the terminal part (loop pipe side) of the air supply pipe 37 can be reduced. The diameter of the header pipe 36 according to the present embodiment is 150 mm, the diameter of the air supply pipe 37 is 100 mm, the diameter of the loop pipe 38 is 100 mm, the interval between the jet outlets 371 is 50 mm, The diameter is 8 mm, and the drain hole diameter is 8 mm.

Is formed. The twenty-seven inlet-side air groove 46 are formed at an interval of about 1.5 meters, and the nine inner-side air grooves 46 are formed at an interval of about 1.8 meters. Therefore, the outlet side air groove 46 is slightly rougher than the inlet side. Further, along the partition wall 45 on the side opposite to the passage 43 defining the A-1 tank, nine loop pipe grooves (not shown) connecting the air pipe groove 46 are formed.

  And the four air blowers 47 are installed substantially equally in the channel | path 43 adjacent to A-1 tank. These blowers 47 generate an air flow and can be intermittently operated. Each blower 47 is connected to a header pipe 48 arranged on the side of the passage 43 of the partition wall 44. The header pipes 48 distribute the air flow generated by the blower 47 and are connected to nine air supply pipes 49, respectively. These air supply pipes 49 penetrate the partition wall 44 and are accommodated in the groove 46 for the air supply pipe. As shown in FIG. 11, the air supply pipes 49 are each formed with a jet port 491 for supplying air to the accumulated organic waste D so as to be in a staggered arrangement. The spout 491 is covered with a wood chip (not shown) or the like so as not to be clogged with the accumulated organic waste D.

  As shown in FIG. 9 and FIG. 10, the end of the air supply tube 49 formed in this way is connected to the loop tube 50, and this loop tube 50 is accommodated in the above-mentioned groove for loop tube. The loop pipe 50 communicates with each of the air supply pipes 49 so that air can flow between the air supply pipes 49. Therefore, the difference in the air supply amount between the air supply pipes 49 can be reduced, and the difference in the air supply amount between the proximal end part (header pipe side) and the terminal part (loop pipe side) of the air supply pipe 49 can be reduced. In addition, the diameter of the header pipe 48 of the tank A-1 is 150 mm, the diameter of the air supply pipe 49 is 100 mm, the diameter of the loop pipe 50 is 100 mm, the interval between the jet ports 491 is 50 mm, and the diameter of the jet port Is formed to be 8 mm.

  A-2 tank, B-1 tank, and B-2 tank produce return compost, and each tank has fermentation area H and dry area K. Fermentation area H is an area where fermentation of organic waste D proceeds mainly and is located on the input side, and drying area K is an area that promotes drying of organic waste and is located on the extraction side. Yes. In each of the A-2 tank, the B-1 tank, and the B-2 tank, as in the A-1 tank, there are 63 grooves for the air pipe so as to be orthogonal to the traveling direction of the organic waste D (see FIG. (Not shown). Of these air ducts, 18 air ducts on the input side are formed at intervals of 1.65 meters, and 45 grooves on the take-out side are spaced at 0.57 meters. It is formed with. Therefore, the groove for the air supply pipe is about three times as dense as the inlet side. Further, nine loop pipe grooves (not shown) are formed along the partition wall 45 on the side opposite to the passages 43 defining the tanks.

  And in the channel | path 43 adjacent to the fermentation area | region H of each tank, each 2 units | sets of the air blowers 47 are installed substantially equally, and each of the 5 air blowers 47 is located in the position adjacent to the drying section of each tank. They are installed almost evenly. These blowers 47 generate an air flow and can be intermittently operated. In addition, each blower 47 is connected to a header pipe 48 disposed on the passage side of the partition wall 44, similarly to the A-1 tank. The header pipes 48 distribute the air flow generated by the blower 47 and are connected to nine air supply pipes 49, respectively. These air supply pipes 49 pass through the partition wall 44 and are accommodated in the air supply pipe concave grooves 46. As shown in FIG. 11, each air supply pipe 49 is formed with jet nozzles 491 for supplying air to the accumulated organic waste D so as to form a staggered arrangement. Here, the outlet 491 of the drying region K is formed larger than the outlet of the fermentation region H so that the amount of air supplied to the drying region is larger than the amount of air supplied to the fermentation region. These spouts 491 are covered with wood chips (not shown) or the like so as not to be clogged with accumulated organic waste.

  The ends of the air supply pipes 49 formed in this way are connected to the loop pipes 50, respectively, and the loop pipes 50 are accommodated in the loop pipe concave grooves described above. The loop pipe 50 communicates with each of the air supply pipes 49 so that air can flow between the air supply pipes 49. Therefore, the difference in the air supply amount between the air supply pipes 49 can be reduced, and the difference in the air supply amount between the proximal end portion (header pipe side) and the distal end side (loop pipe side) of the air supply pipe 49 can be reduced. In addition, the diameter of the header pipe of A-2 tank, B-1 tank, and B-2 tank is 150 mm, the diameter of the air supply pipe is 100 mm, the diameter of the loop pipe is 100 mm, The distance between the nozzles 491 is 50 mm, the diameter of the nozzle 491 is 8 mm, the distance between the nozzles 491 in the drying region K is 50 mm, and the diameter of the nozzle 491 is 10 mm.

  In addition, as shown in FIG. 12, a drain pipe 51 for discharging water flowing out due to the compaction of the organic waste D is provided in one of the groove 46 for the air supply pipe on the input side of each tank. . The drain pipe 51 passes through the partition wall 44 and communicates with the passage 43. For this reason, the water flowing out on the input side of each tank having a large amount of water of the organic waste D can be discharged into the passage 43.

  Further, a dryer chamber 52 (see FIG. 8) is provided to send the dried air to the drying region. Three dryers (not shown) are installed in the dryer chamber 52, and air adjusted arbitrarily by individual operation control can be supplied from the blower 47.

  In addition, as shown in FIG. 6, rails 53 are laid on the upper surfaces of the partition walls 44 and 45. And the linear stirring machine 54 is equipped so that it can drive | work at the rate of 1 unit | set in 2 tanks. Therefore, one linear agitating machine 54 can travel in the A-1 tank and the A-2 tank, and one linear agitating machine 54 travels in the two layers of the B-1 tank and the B-2 tank. Is possible.

  The linear agitating machine 54 can travel from the take-out side to the take-in side while stirring the organic waste D by rotating a paddle (not shown) counterclockwise, and returns from the take-in side to the take-out side. In some cases, drive up with paddles.

  The product storage building 5 is a facility for storing product compost, and stores the product compost that has been carried in, and can be shipped by packing the product compost.

Next, a method for producing compost by the above-described composting facility will be described.
First, the raw material receiving / mixing building 2 receives organic waste D such as manure, which is carried by a truck, and dry grass. And solid part (solid content), dry grass, and returned compost are mixed among organic wastes D, such as manure, and water is adjusted and it is set as a raw material. In this way, the mixed and adjusted raw materials are carried into the primary fermentation building 3 by a transport machine such as a wheel loader.

  The organic waste D carried into the primary fermentation building 3 accumulates in the primary fermentation building 3 while supplying air by the blower 35. The aerobic microorganisms contained in the organic waste D are fermented while generating heat, and the temperature of the organic waste D is raised to about 75 ° C. As a result, the water evaporates and various germs such as Escherichia coli are killed. Thus, the organic waste D deposited for about 7 days in the primary fermentation building 3 is adjusted to have a moisture content of 80% to 90%. In addition, when moisture flows out from the organic waste D due to the consolidation of the accumulated organic waste D, it is discharged from each fermenter 33 to the passage soil 34 by the drain pipe 39.

  Next, the organic waste D primarily fermented in the primary fermentation building 3 is carried out by a transporting machine such as a wheel loader, and the A-1 tank, A-2 tank, B-1 tank, B of the secondary fermentation building 4 -Put into each inlet side of the tank-2.

  In the secondary fermentation building 4, by arbitrarily operating the blower 47 in the A-1 tank and the A-2 tank, an arbitrary amount of air is discarded via the header pipe 48, the air supply pipe 49, and the loop pipe 50. While supplying the product D, the linear agitator 54 is moved from the take-out side to the input side in the order of the A-1 tank and the A-2 tank, and the paddle is rotated counterclockwise. Then, the primary fermented organic waste D is splashed up and gradually moves from the input side to the extraction side. As a whole, in the A-1 tank and the A-2 tank, organic waste moved from the input side to the extraction side for one day.

  In the A-1 tank, since the organic waste D is supplied with air while being stirred, the aerobic fermentation is promoted, and the fermentation is more effective than when the organic waste D is supplied in a compacted state. Will be promoted. Then, stirring is performed every day, and when the organic waste D input from the input side reaches the extraction side over about 20 days, the organic waste D matures and becomes a product compost having a moisture content of about 65%.

  On the other hand, in the fermentation region H of the tank A-2, since the organic waste D is supplied with air while being agitated, aerobic fermentation is promoted, and air is supplied in a state where the organic waste D is compacted. Fermentation will accelerate more than the case. On the other hand, in the drying area K, a larger amount of air is supplied than the air supplied in the fermentation area H while stirring the organic waste D, so that drying is promoted. And stirring is repeated every day, and when the organic waste D thrown in from the input side reaches the take-out side over about 20 days, the organic waste D ferments and dries, and the return compost having a moisture content of about 40 percent It becomes.

  Also, in the B-1 tank and B-2 tank, an arbitrary amount of air is supplied to the organic waste D through the header pipe 48, the air supply pipe 49, and the loop pipe 50 by intermittently operating the blower 47. On the other hand, the linear agitator 54 is moved from the take-out side to the input side in the order of the B-1 tank and the B-2 tank, and the paddle is rotated counterclockwise. Then, similarly to the A-2 tank, aerobic fermentation is promoted in the fermentation area H of the B-1 tank and B-2 tank, and drying is promoted in the drying area K, and the organic that has reached the extraction side. The system waste D becomes a return compost having a moisture content of about 40%.

  In addition, when water flows out from the organic waste D due to the compaction of the organic waste D deposited on the input side of each tank where the water of the organic waste D is high, a passage is passed from each tank by the drain pipe 51. 43 is discharged.

  Then, the product compost that has reached the take-out side of the tank A-1 is carried out by a transport machine such as a wheel loader and stored in the product storage building 5. Then, the product compost can be shipped in a bag. On the other hand, the return compost that has reached the take-out side of the A-2 tank, B-1 tank, and B-2 tank is transported to the raw material receiving / mixing ridge 2 by a transporting machine such as a wheel loader and the like (subsidiary material (moisture adjusting material) ) Will be used for reuse.

  As explained above, according to the primary fermentation building 3 and the secondary fermentation building (4) according to the present embodiment, the loop pipe 38 (50) in which the ends of the air feeding pipe 37 (49) are connected to each other is provided, Since the air flow is enabled, the difference in the air supply amount between the air supply pipes 37 (49) is reduced, and the difference in the air supply amount between the proximal end portion and the distal end portion of each air supply pipe 37 (49) is reduced. Can do. For this reason, the difference in the aging condition of the composted organic waste D can be reduced, and homogeneous compost can be provided.

  Next, based on FIG. 13 and FIG. 14, the effect of the composting facility according to the present embodiment is verified as compared with the conventionally known composting facility. In addition, FIG. 13 is a conceptual diagram which shows the air piping in the composting facility known conventionally, FIG. 14 is a conceptual diagram which shows the air piping in the composting facility of a present Example.

  As shown in FIG. 13, a conventionally known composting facility includes a blower 60, a header pipe 61 connected to the blower 60, a plurality of air feed pipes 62 connected to the header pipe 61, and an air feed pipe 62 at the bottom. The end of the air supply pipe 62 is closed. Here, the header pipe 61 has a diameter of 75 mm and a length of 12 meters, and the air supply pipe 62 has a diameter of 75 mm and a length of 6 meters. It is assumed that nine air supply pipes 62 are connected to the header pipe 61 at a pitch of 1.5 meters. In the air supply pipe 62, jet holes (not shown) having a diameter of 8 mm are staggered at intervals of 50 mm.

  When the blower 60 is operated without depositing organic waste in a conventionally known composting facility and the amount of air supplied from each outlet is compared, the air supply at the end portion is the same in the same air supply pipe 62 The amount was about five times the air supply amount at the base end, and the air supply amount of the air supply pipe having a large air supply amount was about three times the air supply amount of the air supply pipe having a small air supply amount.

  Here, when the diameter of the header pipe 61 is increased from 75 mm to 150 mm, in the same air supply pipe 62, the air supply amount at the distal end is about three times the air supply amount at the base end portion, and the air supply amount is large. The air supply amount of the air supply pipe 62 was about twice as much as the air supply amount of the air supply pipe having a small air supply amount.

  These differences in the air supply amount are expected to have a significant impact even when organic waste is placed in the fermenter, and hinder the homogenization of the compost that is the product.

  Next, the difference in the air supply amount in the composting facility according to the present embodiment will be verified. As shown in FIG. 14, the composting facility according to the present embodiment includes a blower 70, a header pipe 71 connected to the blower 70, a plurality of air supply pipes 72 connected to the header pipe 71, and a plurality of these air supply pipes 72. Are connected to each other and a loop pipe 73 that allows air to flow therethrough. In addition, except having provided the loop pipe | tube 73, it has the same specification as the composting facility conventionally known as a comparison object.

  When the blower 70 is operated without depositing organic waste in the composting facility disclosed in the present invention and the amount of air supplied from each outlet is compared, the amount of air supplied at the end in the same air supply pipe 72 Is about twice the air supply amount at the base end, and the air supply amount of the air supply pipe 72 having a large air supply amount is about 1.3 times the air supply amount of the air supply pipe having a small air supply amount.

  This means that the difference between at least the air supply amount of the air supply pipe 72 having a large air supply amount and the air supply amount of the air supply pipe 72 having a small air supply amount has been reduced to a negligible level. It is assumed that it contributes to homogenization.

  In this embodiment, the header pipe 71 has a diameter larger than that of the air supply pipe 72, so that the difference between the air supply amount at the distal end and the air supply quantity at the base end is small in the same air supply pipe. As described above, the header pipe 71 having a diameter increased from 75 mm to 150 mm was employed.

  As described above, the composting facility according to the present invention is useful for recycling organic waste, and is particularly suitable for recycling organic waste such as manure.
