<First Embodiment>
Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a charging device, a vacuum fermentation drying device, a foreign matter sorter, etc. in a processing device for a processing object containing an organic substance according to an embodiment of the present invention, and FIG. 2 is a charging device of the processing device. , A side view showing a vacuum fermentation / drying apparatus, a foreign matter sorter, etc., FIG. 3 is a diagram schematically showing a schematic configuration of a vacuum fermentation / drying apparatus of the processing apparatus, and FIG. 4 is a diagram showing a schematic configuration of the foreign matter of the processing apparatus. It is a perspective view which shows the schematic structure of a sorter.

As shown in FIGS. 1 to 4, the processing device (hereinafter, also referred to as “treatment device”) 1 for a processing object containing an organic substance includes a charging device 2, a vacuum fermentation / drying device 3, a foreign matter sorter 4, and the like. ing. In the processing device 1, for example, a processing target containing an organic substance such as municipal waste is charged into the reduced pressure fermentation / drying device 3 by the charging device 2, and the charged target is subjected to reduced pressure fermentation / drying by the reduced pressure fermentation / drying device 3. The process is executed. The dried product obtained by the vacuum fermentation drying process of the vacuum fermentation drying device 3 is sent to the foreign matter sorter 4 by the discharge conveyor 41, and the foreign matter mixed in the dried product is removed by the foreign matter sorter 4.

FIG. 2 shows, for example, a processing device 1 installed in a building A, and a charging device 2, a vacuum fermentation drying device 3, a foreign matter sorter 4, and the like are installed at predetermined positions in the building A. .. Hereinafter, each device provided in the processing device 1 will be described.

The charging device 2 supplies the processing target housed in the charging box 21 to the charging port 30a of the vacuum fermentation drying device 3. The loading device 2 is configured as, for example, a reversing type loading device. The loading box 21 is transported from a storage warehouse or the like to a predetermined position of the loading device 2 by a forklift or the like (not shown). The loading box 21 set at a predetermined position of the loading device 2 is lifted upward along a pair of rails 22 and 22 extending in the vertical direction by driving an electric motor or the like (not shown). When the loading box 21 rises to the upper end of the pair of rails 22 and 22, it rotates around the horizontal axis 23 provided between the pair of rails 22 and 22, and the loading box 21 is turned upside down. Along with the reversing operation of the charging box 21, the object to be processed contained in the charging box 21 is charged into the charging port 30a of the vacuum fermentation drying device 3, but here it is municipal waste. There was a risk that the object to be treated, including organic substances, would scatter and give off a foul odor.

The vacuum fermentation / drying apparatus 3 is known, for example, as described in Patent Document 1, and the object to be treated is stirred while being heated to a predetermined temperature range under reduced pressure, and microorganisms are used. Then, the organic component of the object to be treated is decomposed to obtain a dried product having a reduced volume.

As schematically shown in FIG. 3, the vacuum fermentation / drying device 3 is an abbreviation that is airtightly formed so as to keep the inside below atmospheric pressure as a closed container for accommodating the object to be processed supplied by the charging device 2. It is provided with a cylindrical tank (pressure resistant tank) 30. A heating jacket 31 is provided on the peripheral wall portion of the tank 30, and steam for heating is supplied to the heating jacket 31 from the steam boiler 7. The temperature of the steam supplied from the steam boiler 7 is preferably, for example, about 140 ° C.

Further, a stirring shaft 32 extending in the longitudinal direction (left-right direction in FIG. 3) is provided inside the tank 30 so as to be surrounded by the heating jacket 31. The stirring shaft 32 is rotated at a predetermined rotation speed by the electric motor 32a. The stirring shaft 32 is provided with a plurality of stirring plates 32b spaced apart from each other in the axial direction, and the stirring plate 32b stirs the object to be treated and organic substances are transferred to the rear of the tank 30 after the fermentation and drying are completed. It is designed to be sent to.

An organic material charging port 30a supplied from the charging device 2 is provided in the upper part of the center in the longitudinal direction of the tank 30, and the organic material charged from the charging port 30a is heated by the heating jacket 31 while the stirring shaft is heated. It is agitated by 32 rotations. Then, after a lapse of a predetermined time, the treated organic matter (dried matter) is discharged from the discharge unit 30b provided at the lower part of the tank 30. A hydraulic motor may be used instead of the electric motor 32a.

At the upper part of the tank 30, a guide portion 30c for guiding the steam generated from the heated organic substance to the condensing portion 33 is provided. In the present embodiment, two guide portions 30c are provided, and each guide portion 30c is arranged on both sides of the tank 30 in the longitudinal direction with the loading port 30a interposed therebetween. The condensing unit 33 includes a plurality of cooling pipes 33b supported by a pair of heads 33a, and a cooling water path 80 is provided between the plurality of cooling pipes 33b and the cooler 8. .. In the present embodiment, the condensing portion 33 extends in parallel along the longitudinal direction of the tank 30, and the condensing portion 33 is arranged on the rear side of the charging port 30a and the guide portion 30c.

Next, the hypochlorous acid gas diffusion mechanism 100 in the first embodiment will be described. One end of the chemical liquid pipe 101 is connected to the water receiving tank 81 of the cooler 8, and the other end is connected to the hypochlorite water storage container 104 via the on-off valve 102 and the chemical liquid pump 103. The concentration of hypochlorous acid water contained in this storage container is 50 to 5000 mg / L, and the concentration of hypochlorous acid in the water receiving tank 81 is approximately 30 mg / L by adjusting the on-off valve 102 and the chemical solution pump 103. Hypochlorous acid water is supplied from the storage container 104 as described above.

Then, the cooling water that circulates in the cooling pipe 33b in the condensing portion 33 and whose temperature has risen due to heat exchange with the high-temperature steam flows through the cooling water path 80 and is cooled as schematically shown by an arrow in FIG. It flows into the water receiving tank 81 of the vessel 8. The cooler 8 is provided with a pump 82 that pumps the cooling water containing the hypochlorite water in the water receiving tank 81, and a nozzle 83 that injects the pumped cooling water. The cooling water jetted from the nozzle 83 receives air from the fan 85 while flowing down the lower part 84, the temperature drops, and the cooling water flows into the water receiving tank 81 again.

During this period, the cooling water containing the hypochlorite water is sprayed from the nozzle 83, and while the cooling water flows down at the lower part 84, the hypochlorite dissolved in the cooling water is gasified, and the hypochlorite is gasified from the fan 85. The hypochlorite concentration in the water receiving tank 81 is adjusted so that the chlorite gas is blown and the hypochlorite gas concentration in the building A is set to 0.05 to 0.5 ppm. As a result, for example, ammonia, which is a malodor component, is decomposed by hypochlorous acid, and the malodor can be deodorized.

The cooling water cooled by the cooler 8 is sent by the cooling water pump 86, sent to the condensing portion 33 by the cooling water path 80, and circulates in the plurality of cooling pipes 33b again. Then, after the temperature rises due to heat exchange with the steam generated inside the tank 30 as described above, it flows through the cooling water path 80 again and flows into the water receiving tank 81 of the cooler 8.

In addition to the cooling water that circulates as described above, in the cooler 8, the condensed water in which the steam generated from the heated organic matter is condensed in the condensing portion 33 is also injected. Although not shown, condensed water generated by heat exchange with high-temperature steam is collected below the condensed portion 33. Further, a vacuum pump 36 is connected to the condensing portion 33 via a communication passage 35 to reduce the pressure in the tank 30.

That is, by the operation of the vacuum pump 36, air and condensed water are sucked out from the condensing portion 33 through the communication passage 35, and further, air and steam in the tank 30 are sucked out through the communication passage 34 and the guide portion 30c. .. In this way, the condensed water is sucked out from the condensing unit 33 to the vacuum pump 36, and is guided from the vacuum pump 36 to the water receiving tank 81 of the cooler 8 by the water guide pipe.

The condensed water thus guided to the water receiving tank 81 of the cooler 8 is mixed with the cooling water, pumped up to the pump 82 as described above, injected from the nozzle 83, and then cooled while flowing down the flow bottom 84. To. The condensed water contains the same microorganisms as those added to the organic matter in the tank 30, and the malodorous components contained in the condensed water are decomposed so that the malodor does not dissipate to the outside of the tank. It has become.

Explaining the operation of the vacuum fermentation drying device 3 having the above configuration, the organic matter contained in the tank 30 is agitated with the rotation of the stirring shaft 32 while being heated by the heating steam supplied to the heating jacket 31. Then, the organic matter contained in the tank 30 is effectively heated and stirred by receiving the heating from the outside by the heating jacket 31 surrounding the inside of the tank 30 and the heating from the inside by the stirring shaft 32 or the like. The organic matter is agitated by the shaft 32. In addition, since the pressure is reduced by the operation of the vacuum pump 36, the boiling point in the tank 30 is lowered, and the water evaporates in the temperature range where the decomposition of the organic component of the organic substance is promoted by the microorganism.

In the vacuum fermentation / drying step by the vacuum fermentation / drying apparatus 3, one step (1 cycle) is preferably, for example, 2 hours, and the fermentation step is first to decompose the organic component of the organic substance over 30 minutes. When the inside of the tank 30 is reduced to −0.06 to −0.07 MPa (gauge pressure; hereinafter, the gauge pressure is omitted), the water temperature in the tank 30 is maintained at 76 to 69 ° C. (saturated steam temperature). As a result, fermentation and decomposition of organic substances are promoted by microorganisms described later.

Next, the organic matter being fermented will be dried for 1.5 hours. Therefore, when the pressure inside the tank 30 is further reduced to −0.09 to −0.10 MPa, the moisture temperature in the tank is maintained at 46 to 42 ° C. (saturated steam temperature), and the drying of organic substances is sufficiently promoted. It becomes a process. Then, as the microorganism to be added to the organic matter in the tank 30 when performing such a drying treatment, for example, as described in Patent Document 2, a plurality of types of indigenous bacteria were used as a base and cultured in advance. The complex effective microorganism group is preferable, and the so-called SHIMOSE 1/2/3 group is the center of the colony.

SHIMOSE 1 was sent to FERM BP-7504 (Ministry of Economy, Trade and Industry, National Institute of Advanced Industrial Science and Technology, National Institute of Advanced Industrial Science and Technology, Patent Microorganisms Depositary Center (1-1-3, Higashi, Tsukuba City, Ibaraki Prefecture, Japan), March 14, 2003. It was deposited internationally in Japan). In addition, SHIMOSE 2 is a microorganism belonging to FERM BP-7505 (internationally deposited like SHIMOSE 1) and Pichiafarinosa, which has resistance to salt, and SHIMOSE 3 is a microorganism belonging to FERM BP-7506 (SHIMOSE 1). Similarly, it is a microorganism belonging to Staphylococcus (which was deposited internationally).

Here, the procedure of the vacuum fermentation drying treatment of the organic substance by the vacuum fermentation drying apparatus 3 will be described. First, the object to be treated containing an organic substance is put into the vacuum fermentation drying device 3. At this time, the lid of the charging port 30a of the tank 30 of the vacuum fermentation drying device 3 is opened, and the organic matter contained in the charging box 21 by the charging device 2 is charged from the charging port 30a. Then, the lid of the charging port 30a is closed, and the inside of the tank 30 is sealed in an atmospheric pressure state.

Next, after adding a predetermined microorganism to the organic matter in the tank 30, the atmosphere opening valve (not shown) is closed to seal the inside of the tank 30. Then, the inside of the tank 30 is heated under reduced pressure to promote fermentation and drying of the organic component of the organic substance contained in the tank 30. That is, heating steam is supplied from the steam boiler 7 to heat the inside of the tank 30.

Then, the inside of the tank 30 is heated by the heating steam, the stirring shaft 32 is rotated at a predetermined rotation speed (for example, about 8 rpm), and the inside of the tank 30 is depressurized by the operation of the vacuum pump 36. The temperature inside the tank 30 becomes the optimum environment for the activity of the microorganism, and the decomposition of the organic component of the organic substance by the microorganism is suitably promoted. The rotation speed (8 rpm) of the stirring shaft 32 is an example, and may be another value as long as the organic component of the organic substance can be decomposed.

When a predetermined time (for example, about 2 hours) has elapsed while maintaining the temperature and pressure in the tank 30 in this way, the operation of the vacuum pump 36 and the steam boiler 7 is stopped, and the atmosphere release valve is opened. It is in an atmospheric pressure state. On the other hand, the stirring shaft 32 is rotated in the reverse direction, the lid of the discharge portion 30b of the tank 30 is opened, and the dried product is discharged from the tank 30. At this time, the volume of the dried product discharged from the tank 30 is reduced.

Then, the dried product after the treatment, which has been subjected to the low-pressure fermentation and drying treatment by the low-pressure fermentation and drying apparatus 3, is conveyed to the foreign matter sorter 4 by the discharge conveyor 41. That is, the discharge conveyor 41 conveys the dried matter discharged from the discharge unit 30b at the lower part of the tank 30 of the vacuum fermentation drying device 3 to the foreign matter sorter 4 provided at a position higher than the discharge unit 30b. The foreign matter sorter 4 removes foreign matter, specifically metals and plastics, that are not decomposed by the vacuum fermentation and drying treatment by the vacuum fermentation and drying apparatus 3.

The foreign matter sorter 4 includes a magnetic separator 42 and a vibration sieving machine 43, as outlined in FIG. The magnetic separator 42 is, for example, a hanging type, and is suspended on a discharge conveyor 41. The magnetic separator 42 attracts a metal fitting, a magnetic material such as an iron piece (indicated by a black circle) from the dried material conveyed by the discharge conveyor 41 by a magnet, and continuously discharges the container by a belt 42b moving between the pulleys 42a. It is configured to discharge to 42c. The magnetic separator 42 removes metal fittings and metals such as iron pieces mixed in the dried product.

The vibrating sieving machine 43 sifts large foreign substances from the dried matter discharged from the vacuum fermentation drying device 3 and conveyed by the discharging conveyor 41. The vibration sieving machine 43 includes a wire mesh 43a having a mesh (opening) of a predetermined size, and a vibration motor 43b that vibrates the wire mesh 43a. The vibration sieving machine 43 is supported on the lower base 43d by a plurality of (for example, four) coil springs 43c. Further, the wire mesh 43a is provided in a state of being inclined diagonally downward, and one end side (left end side in FIG. 4) of the wire mesh 43a is provided at a position lower than the other end side (right end side in FIG. 4). ing. In the present embodiment, the mesh of the wire mesh 43a is set to a size of 5 mm × 5 mm. The mesh size is an example and may be another value. The vibrating sieving machine 43 sorts out plastics and the like mixed in the dried product.

As described above, since the vibration sieving machine 43 is floatingly supported with respect to the lower base 43d by the coil spring 43c, the dried material supplied from the discharge conveyor 41 to the wire mesh 43a is sieved by the driving of the vibration motor 43b. Specifically, the dried matter passes through the mesh of the wire mesh 43a, falls downward, and is stored in the storage container 44 arranged below the vibrating sieve 43. On the other hand, foreign matter larger than the dried material cannot pass through the mesh of the wire mesh 43a, so that it slides down or rolls down along the inclined surface of the wire mesh 43a and moves to one end side (front side), and the vibration sieving machine 43. It is discharged to the discharge container 43e arranged in the front lower part of the above. At this time, not only foreign matter such as plastic but also dried matter having a size larger than the mesh of the wire mesh 43a is discharged to the discharge container 43e. However, as described above, the dried product is suitable for sieving by being fermented and dried by the vacuum fermentation drying device 3 and the volume is reduced, and most of the dried products other than foreign substances pass through the mesh of the wire mesh 43a. Then, it is stored in the storage container 44.

In this way, foreign substances such as metal pieces and plastics are removed from the dried product, and high-quality organic fertilizer is stored in the storage container 44. In the embodiment of the present invention, the dried product produced in the final step is used as an organic fertilizer as a valuable resource, but by adding an additive, the dried product can be used as a valuable organic feed for livestock. Or, it may be used as an organic feed for aquaculture.

It is composed of a hypochlorous acid water storage container 205 connected via a pump 204.

Therefore, by opening the on-off valve 203 and driving the chemical solution pump 204, hypochlorous acid water is sprayed from the spray nozzle 201 in the same direction as the blowing direction of the fan 85, so that the blowing of the fan 85 and the hypochlorous acid are performed. The hypochlorous acid water is mixed and gasified, and these hypochlorous acid gases are diffused throughout the building A where the treatment device 1 is installed, and this hypochlorous acid gas decomposes malodorous components such as ammonia to deodorize the malodor.

Also in the fourth embodiment, only the hypochlorous acid gas diffusion mechanism 400 is different from the first embodiment. In the following description of the fourth embodiment, the differences from the first embodiment will be mainly described, and the description of the configuration common to the first embodiment will be omitted.

The hypochlorous acid gas diffusion mechanism 400 is connected to a pan 401 provided in the vicinity of the fan 85 of the cooler 8 in the outward direction, one end connected to the pan 401, and the other end via an on-off valve 403 and a chemical liquid pump 404. It is composed of a pipe 402 connected to the hypochlorous acid water storage container 405 and a heater 406 arranged on the back surface of the bottom of the pan 401.

When the on-off valve 403 is opened to drive the chemical solution pump 404, a small amount of hypochlorite water is supplied from the hypochlorite water storage container 405 to the pan 401 via the pipe 402.

Further, similarly to the above, the fifth embodiment of the present invention will be described with reference to FIG. Also in the fifth embodiment, only the hypochlorous acid gas diffusion mechanism 500 is different from the first embodiment. In the following description of the fifth embodiment, the differences from the first embodiment will be mainly described, and the description of the configuration common to the first embodiment will be omitted.

In the present invention, the hypochlorous acid gas diffusion mechanism 500 has a first pipe 502 having one end open in the vicinity of the fan 85 of the cooler 8 and the other end connected to the discharge port of the ejector 501, and one end being an on-off valve. A second pipe 505 connected to the hypochlorous acid water storage container 504 via 503 and the other end connected to the hypochlorous acid water supply port of the ejector 501, and one end connected to the compressor 506 and the other end. It is composed of a third pipe 507 connected to the air inlet of the ejector 501.

Therefore, the on-off valve 503 is opened so that hypochlorous acid water can be supplied from the hypochlorous acid water storage container 504 to the supply port of the ejector 501 via the second pipe 505, and the compressor 506 is driven to drive the compressor. When air is blown from 506 to the ejector 501 via the third pipe 507, the hypochlorous acid water is sucked into the air flow inside the ejector 501, gasified, and gasified from the ejector 501 discharge port through the first pipe 502 to the hypochlorous acid gas. By injecting the gas, the hypochlorous acid gas is diffused throughout the building A by the fan 85 of the cooler 8, and the malodorous component such as ammonia is decomposed to deodorize the malodor.

The embodiments disclosed this time are exemplary in all respects and are not grounds for limited interpretation. The technical scope of the present invention is not construed solely by the embodiments described above, but is defined based on the description of the scope of claims. In addition, the technical scope of the present invention includes all modifications within the meaning and scope equivalent to the scope of claims.
