BACKGROUND OF THE INVENTION
The present invention relates to a greenhouse with a bioreactor, and more particularly, an apparatus that combines a bioreactor that decomposes and re-synthesizes biomass with highly thermophilic bacteria and a greenhouse, fertilizes and generates biomass such as food waste The present invention relates to an apparatus that can effectively contribute to material circulation by utilizing carbon dioxide gas and heat for growing plants in a greenhouse.
[0002]
[Prior art]
Greenhouses are used to grow various ornamental or production plants, and farmers have traditionally planted fermentable waste such as fallen leaves, straw and horse dung into the soil, and organic fertilizers by microorganisms in the soil It has been known that a hotbed that uses forcing cultivation such as seedlings using the fermentative heat generated at that time is known.
[0003]
In addition, the materials on the earth are finite, and various evils due to the rapid expansion of the population have occurred since history, and attempts to shift to a recycling society have been made in various places.
[0004]
[Problems to be solved by the invention]
By the way, as is well known, urbanization has progressed, and measures to deal with garbage from households and restaurants have become an important administrative issue. Various processing methods have been proposed and implemented in the past. As a result, it is recognized that there is a tendency to concentrate in the direction of fertilizer while reducing the volume by microorganisms and to recycle.
[0005]
The present inventor participated in a project to reduce the decay when the garbage generated in the sink was compressed and dehydrated under the sink into a dry state, and then discarded. Has been developed (Japanese Patent No. 2120653) capable of compressing up to 20-50%. However, this compressed product can only be incinerated or landfilled as it is.
[0006]
Accordingly, the inventor has focused on the fact that the compressed / dehydrated product is suitable for the propagation of microorganisms, and has independently started the study of fertilizing raw garbage by a microbial reaction. As a result, highly thermophilic bacteria that are slightly present in a dormant state in the soil (bacteria that grow at a temperature of 70 ° C. or higher, and some bacteria that grow at 200 ° C. or higher) are, for example, 70 to 85 ° C. When cultivating in raw garbage kept at temperature, we found that organic matter such as nitrogen in raw garbage can be decomposed and re-synthesized to the inorganic level by genetic information of highly thermophilic bacteria. A patent application was filed on June 15, 2001 as a device (hereinafter referred to as a bioreactor).
[0007]
This method of treating garbage with highly thermophilic bacteria is to treat garbage in a household with a small device that fits in the space under the sink, and to which moisture has adhered for about 2 to 4 months. The volume is reduced to 3 to 5%, and there is a feature that organic fertilizer that is easy to be mineralized can be obtained without containing bacteria such as spoilage bacteria.
[0008]
The bioreactor needs to be heated in order to grow highly thermophilic bacteria, and the garbage also generates heat as the decomposition and resynthesis reaction progresses. With a simple control means, almost complete automatic operation is possible.
[0009]
By linking the bioreactor with the above characteristics to the greenhouse, it is possible to self-suffice clean organic vegetables using generated fertilizers such as heat, carbon dioxide gas, etc., without discarding any garbage to the outside. It was thought that.
[0010]
That is, the object of the present invention is to use the bioreactor from a large one such as a garbage disposal from a large kitchen to a small one for general households, cultivating vegetables using all the generated garbage as a fertilizer, The purpose of the present invention is to provide a greenhouse equipped with a bioreactor capable of practicing a circulation system by culturing, cultivating and the like so as not to dispose of raw garbage.
[0011]
[Means for Solving the Problems]
A greenhouse equipped with the bioreactor of the present invention for achieving the above object comprises a greenhouse and a bioreactor, and the bioreactor is provided with a heating means and a stirrer, and wet bulk biomass in the presence of air. At least a part of the exhaust gas containing carbon dioxide generated by decomposition and resynthesis by highly thermophilic bacteria is supplied into the greenhouse, and the stirrer performs stirring that feeds in the direction of the stirring axis and feeds in the radial direction. A blade is provided, and the biomass is circulated in the bioreactor at a slow speed in the direction of the rotation axis and in a direction crossing the axis, and a high temperature portion generated in a portion close to the heating means in the bioreactor; A low-temperature portion in contact with the supplied air, and at least intermittently supplying the wet bulk biomass anew It is obtained so as to perform the decomposition resynthesis.
[0012]
In the present invention, the extreme thermophile means that the extreme thermophile collects soil, mixes it with bulk biomass such as sawdust, and keeps it at a high temperature of 70 ° C or higher, preferably 85 ° C or higher. In the group of fungi existing in the soil, it means a fungus that can survive.
The soil may be collected anywhere, but it is usually preferable to collect it from fertile soil such as under fallen leaves. In addition, soil fungi that are subjected to the sterilization treatment (fungi in the soil) may be added as collected, but those that have been transferred to a carrier such as wood chips such as sawdust or peat moss will not stain the surroundings. Is preferable. In addition, as long as the strain of the extreme thermophile contained in a soil microbe is equipped with the DNA program which decomposes | disassembles and re-synthesizes biomass, what kind of thing may be sufficient.
[0013]
The biomass used in the present invention is not particularly limited. For example, cooking waste, food waste such as meals, agricultural waste that has been cut off or sorted out in fields, collection areas, etc., livestock and fish, etc. Such as demolition residues and livestock droppings. However, the subject of the present invention is not limited to this, and can also be applied to biomass lacking the nutritional balance required for highly thermophilic bacteria. In this case, when a problem such as a decrease in the survival rate of the extreme thermophile occurs, it is preferable to supplement the lack of nutrients. In that respect, it can be considered that the garbage generated from the nutritionally balanced menu can satisfy the nutritional balance for the bacteria.
[0014]
In the present invention, the greenhouse refers to the outside of a greenhouse in a normal sense, such as a vinyl house, where plants are grown in a space partitioned with a synthetic resin plate or sheet such as polycarbonate or vinyl outside of glass. A glass roof covering a part of the roof of a simple greenhouse, a greenhouse attached to a house, a solarium, etc., a room where sunlight is sufficiently inserted into a part of the house, the rooftop of a building, a relatively steep ordinary house, etc. Temporary things made on the attic, veranda, terrace, etc. are also included.
[0015]
The decomposition and resynthesis reaction by highly thermophilic bacteria naturally requires air. Therefore, it is necessary to supply fresh air to the bioreactor. As the air supplied to the bioreactor, the air in the greenhouse can be taken into at least a part of the total supply air, and in particular, it is possible to save power during the cold season and save heating costs.
[0016]
In the exhaust gas supplied to the greenhouse, not only immediately after the raw garbage is input as biomass, but also particularly when the odorous raw garbage is used, in general, the specific odor and decomposition / resynthesis of the exemplified biomass are used. Odors that occur during the process may arrive. Therefore, the exhaust gas can be supplied to the greenhouse after deodorizing.
[0017]
The deodorizing method is not particularly limited. For example, activated carbon, charcoal, and other porous materials such as pumice, diatomaceous earth, sawdust, etc. can be used in addition to a chemical method using ozone or the like. Ammonia odor and the like can be removed by passing over an acidic liquid. In addition, for a very slight odor, scenting with a fragrance may be effective.
[0018]
The greenhouse requires heating such as in the cold season, and as described above, the bioreactor of the present invention partially heats a part of the biomass in the contents to 70 ° C. or higher, preferably 85 ° C. or higher. Requires heating means. Therefore, a heat storage device that keeps the exhaust temperature at a higher temperature can be arranged between the bioreactor and the greenhouse, and can be supplied to the bioreactor and the greenhouse after passing through the heat storage device.
[0019]
Moreover, when using solid as said deodorizing agent, it can be set as a structure similar to a thermal storage apparatus. Therefore, the deodorizing device and the heat storage device can be integrated, and a vertical type can be used to reduce the installation area.
[0020]
The heat storage device is fermented with moist air such as sawdust and fallen leaves, filled with biomass that becomes compost, passes through the packed bed through the exhaust from the bioreactor, and exhausts and greenhouses with the heat that the packing ferments. Can get warm.
[0021]
That is, the air in the greenhouse can be warmed by the heat dissipated from at least one of the bioreactor and the heat storage device of the present invention, and can be used for heating when the temperature in the greenhouse is lowered. As a specific method in this case, in a greenhouse where there is room for placing a bioreactor and a heat storage device in the greenhouse, exhaust is supplied to the greenhouse when it is installed in the greenhouse and curtains, movable partitions, etc. are not used for heating. It is possible to prevent excess heat contained therein from being transmitted to the plant cultivation area.
[0022]
Furthermore, a hut or container (household room) equipped with a bioreactor, deodorizing device and heat storage device is installed beside the greenhouse (exhaust from the heat storage device), and the greenhouse air supplied to the bioreactor is piped. Etc. can be supplied. The deodorizing device and the heat storage device can also be heated by an electric heater or the like.
[0023]
If the biomass newly supplied to the bioreactor is raw garbage, even if it is put in the state of adhering water, the volume is reduced by almost 1/2 in the first day and reduced to almost 1/5 in 10 days. To a final volume of approximately 3-5%. Therefore, since garbage is generated in a meal time cycle even for business use, biomass is generally supplied intermittently. On the other hand, since the final volume reduction rate is extremely high as described above, the removal can be performed by various methods such as allowing the reaction chamber to become full because overflowing is performed.
[0024]
In addition, it has been confirmed that the decomposition and resynthesis of biomass by the highly thermophilic bacterium of the present invention is decomposed until the original shape disappears in approximately one week, for example, when cooked fish bone is directly put into a bioreactor. However, the average residence time for the biomass to stay in the bioreactor is 30 days, preferably 60 days, and more preferably 90-120 days. The number of days of residence can be selected appropriately depending on the degree of volume reduction and the quality of the fertilizer.
[0025]
However, a decrease in temperature, particularly in the vicinity of the heater, increases the risk of miscellaneous bacteria growing at low temperatures, and increases the possibility that the activity of highly thermophilic bacteria will decrease. Therefore, the garbage disclosed in the above-mentioned Japanese Patent No. 2120653 can be put into the bioreactor after the garbage is compressed and dehydrated.
[0026]
As described above, the stirrer attached to the bioreactor is provided with the stirring blades that perform the feed in the direction of the stirring axis and the feed in the radial direction as described above, and the bioreactor in the direction of the rotation axis and the direction crossing the axis. When the biomass is circulated at a slow speed and sent in a certain direction as the reaction proceeds, the processed biomass and the biomass being processed can be separated naturally.
[0027]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment with reference to the accompanying drawings will be described to describe the present invention more specifically.
[0028]
A greenhouse 1 equipped with a bioreactor according to an embodiment shown in FIG. 1 is a greenhouse 3 standing on an open field 2 and provided with a bioreactor 4. The heat insulating material 3b is used so that the heat in the greenhouse 3 is not dissipated to the outside from the floor 3a. Moreover, the code | symbol 5 shown in FIG. 1 is a curtain, 6 is a skylight for ventilation, 7 is a ventilation fan, 8 is a heat insulation curtain, 9 is a planter, 10 is a planter rack.
[0029]
The bioreactor 4 used in the present embodiment was used in combination with a deodorizer 11 and a heat accumulator 12 as shown in FIGS. As shown in FIG. 2, the deodorizer 11 and the heat accumulator 12 are stacked and accommodated in the heat-retaining room 13, and the heat-retaining room 13 and the greenhouse 3 are communicated with each other through a window 13b with a shutter 13a.
[0030]
The bioreactor 4 has a semi-cylindrical bottom portion 4a, two rotating shafts 14 are arranged on the cylindrical shaft, and horizontal type stirrers 15a and 15b (hereinafter, the stirrer is generically referred to by reference numeral 15). Arranged.
[0031]
Each stirrer 15 is equipped with a stirring blade 15c that feeds in the axial direction and the radial direction, respectively, and is rotated forward and reverse by the control device 16 (FIG. 4) to feed the biomass 17 in the direction parallel to the shaft, The mixture is moved in the direction of the white arrow 18 shown in FIG. The drive devices for the agitators 15a and 15b are driven independently by electric motors 16a and 16b controlled by the control device 16 as shown in FIG. Note that reference numeral 15d shown in FIG. 4 is an intermediate bearing, 16c is a sprocket attached to each rotating shaft 14, and reference numeral 16d indicated by a two-dot chain line denotes a chain attached to the sprocket 16c. . In addition, 4b shown in FIG. 2 is a heat insulating material, 15d is an intermediate bearing.
[0032]
New biomass (in the case of the present embodiment, garbage) was introduced from an inlet 20 (FIG. 3) provided in a lid 19 (FIG. 2) formed from the ceiling of the bioreactor 4. On the opposite side, an outlet 21 is provided, and a similar lid 19 (represented by the same reference numeral) is provided.
[0033]
A planar heating device 22 (FIG. 2) made of an electric heater is arranged on the entire surface of the bottom 4a of the bioreactor 4 so that the internal temperature can be maintained at a predetermined temperature. Furthermore, the amount of heat generation can be increased on the side of the insertion port 20 in order to compensate for the temperature drop when the garbage is introduced. In that case, it is recommended that the lid is not easily opened with a key or the like so as not to throw in garbage from the outlet 21 side.
[0034]
Supply of oxygen is required for the decomposition and resynthesis reaction of the biomass 17 by the highly thermophilic bacterium (not shown). Therefore, in the present embodiment, an exhaust pipe 23 is connected between the bioreactor 4 and the deodorizer 11, and exhaust (substantially increased in carbon dioxide content) 25 discharged from the bioreactor 4. Was introduced into the deodorizer 11, discharged from the heat accumulator 12 into the warming chamber 13, taken into the air supply pipe 26 from the warming chamber 13, and sucked into the bioreactor 4. 2 and 3, reference numeral 25a denotes an exhaust fan, 26a denotes an air supply fan, and 26b denotes a hood of the air supply pipe 26.
[0035]
Next, the deodorizer 11 and the heat accumulator 12 will be described. Each of the deodorizer 11 and the heat storage device 12 is a stack of containers having the same shape and made of a shallow plastic bottom, and the deodorizer 11 at the bottom stage processes the exhaust pipe end 23b into a bifurcated shape (FIG. 3). ), A plurality of outlets 11a are opened downward (FIG. 2), exhaust 25 is circulated through a deodorizer (not shown) filled in the deodorizer 11, and an opening 12a (see FIG. It was made to flow into the heat accumulator 12 from 2).
[0036]
In addition to activated carbon, pumice and the like, sawdust (both not shown) can be used as the deodorizer. When sawdust is used, in addition to deodorizing action, it is captured by microorganisms such as ammonia and other low-molecular compounds, and converted to organic polymers by the DNA gene replication action of microorganisms, and converted to organic fertilizers that are easily mineralized. .
[0037]
The deodorizer 11 is provided with a drain pipe 27a and a drain collecting container 27 as shown in FIG. This is because the upper space of the biomass 17 in the bioreactor 4 evaporates because the reaction water at the time of resynthesis (biosynthesis) is warmed and evaporated in addition to the adhering moisture of newly input biomass. It contains a lot of water vapor. The water vapor is collected in the exhaust pipe 23 and the deodorizer 11 to collect water that is condensed.
[0038]
Further, on the side of the bioreactor 4 of the exhaust fan 23a and the air supply fan 26a shown in FIG. 3, a baffle plate 23b is attached inside the exhaust pipe 23 as shown in FIG. A cup 27b is attached (the same applies to the air supply pipe 26).
[0039]
The heat accumulator 12 is filled with biomass such as fallen leaves (not shown), and leaves the fallen leaves through passage of warm exhaust 25 containing water vapor, captured by microorganisms in other biomass, and microbial DNA genes Organic fertilizer that is easy to become inorganic due to organic polymerization by replication information action. In addition, the internal temperature of the warming chamber 13 can be increased by the greenhouse gas such as carbon dioxide gas generated from the bioreactor 4, the deodorizer 11, and the heat accumulator 12 and the incidence of sunlight, thereby heating the heat accumulator 12.
[0040]
Therefore, in the heat accumulator 12, the microbial reaction is accelerated during the day and heat is absorbed until the equilibrium is reached, and energy is stored until the equilibrium is reached at night, and the greenhouse 3 can be warmed by radiating heat until the equilibrium is reached. .
[0041]
The exhaust 25 containing the air in the greenhouse 3 and the greenhouse gas such as carbon dioxide is mixed with the air in the greenhouse through the window 13b attached to the greenhouse 13 to dilute the carbon dioxide in the greenhouse 13 and to the greenhouse 3 side. By supplying the carbon dioxide gas to and the bioreactor 4 and being distributed to the deodorizer 11 and the heat accumulator 12, the effect of each reaction is exhibited, and energy is accumulated in each device and the entire apparatus. Further, when the temperature in the greenhouse rises during the daytime or in summer, the curtain 5 can be pulled to make it difficult for the heat around the heat-retaining greenhouse 13 to be transmitted to the greenhouse.
[0042]
As long as the essence of the present invention is not changed, the shape and arrangement of the bioreactor 4, the deodorizer 11, the heat storage device 12, the thermal storage chamber 13, and the like, the manner of piping associated therewith, whether drain is collected or discharged, etc. It can be implemented in any form according to the actual situation.
[0043]
The greenhouse 3 described above was a greenhouse or a sunroom-like one having a floor area of about 100 m @ 2 and having a roof and a surrounding wall made of a transparent plate laminated with a gap between two polycarbonate plates. The bioreactor is designed to treat raw garbage (including garden weeds. In this case, it will be supplemented with highly thermophilic bacteria) with a target of 3 kg / D and a peak of 5 kg / D. A stainless steel drip-proof type having a height of 960, 580, and 700, a volume of 90 liters, a heater capacity of 300 W, and power consumption of 100 W / h was used. The capacity of the deodorizer 11 was 100 liters, the capacity of the heat accumulator 12 was 200 liters, the volume of the thermal storage room 13 was 1.3 m @ 3, and the roof and walls were covered with commercially available glass plates. Moreover, it designed so that the average residence time which passes the deodorizer 11-heat storage 12 of the exhaust_gas | exhaustion 25 might be 90 second.
[0044]
Next, a method for operating the bioreactor 4 will be described. First, the bioreactor 4 is filled with readily available biomass such as sawdust, and as much fertile soil as possible is collected and put into the bioreactor 4. The soil used in the present embodiment was collected from the forest adjacent to the inventor's address. The amount in this case is not particularly limited, but if it is too small, it takes time for the growth of highly thermophilic bacteria, which is not preferable. In the case of the bioreactor 4 having the above capacity, about 1 kg is suitable empirically.
[0045]
Next, the heating device 22 is turned on, and the contents are controlled so that the high temperature portion is 70 ° C. or higher, preferably 85 ° C. or higher, the low temperature portion is 40 ° C. or higher, and the moisture content is 15 to 30%. The color of biomass (in this case sawdust) changes from reddish brown to blackish brown day by day. The sawdust is used as biomass that can be easily obtained without being unclean, and any other thermophile can be cultured. In principle, the sawdust may be raw garbage.
[0046]
When ready for operation, the biomass to be treated (in the case of this embodiment, raw garbage from the home, removed weeds, etc.) will be appropriately selected from September 12, 2001, once a day in principle. It has been introduced and continues today. Table 1 shows data for two days among the temperatures measured for each part recently. In addition, the thermometer used used the rod-shaped alcohol thermometer attached to each measurement part.
[0047]
[Table 1]

As shown in Table 1, it has been found that a warming effect that can reach a maximum temperature of 37 ° C. in the daylight can be obtained at 14 ° C. or higher even when the temperature inside the greenhouse is -3 to 10 ° C. outside. Therefore, it can be made available by producing useful fertilizer from raw garbage and other biomass that can only be discarded and releasing the generated heat and carbon dioxide into the greenhouse 3.
[0048]
The planter 9 was sown with rape, peas, spinach, leek, bamboo grass, parsley, and ashitaba on January 5, 2002, in addition to spinach (not shown) grown in another greenhouse. The sown seeds subsequently germinated on January 11 and then began to germinate in sequence, finally germinating at a germination rate of 65-97%.
[0049]
The greenhouse equipped with the bioreactor according to the second embodiment shown in FIG. 6 is obtained by remodeling a part of the second floor part of a detached house into the greenhouse 3, and the substantial configuration is the same as that of the greenhouse 3 shown in FIG. Since it is set as this structure, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted. In FIG. 6, reference numeral 30 denotes a first-floor wall, 31 a first-floor floor, 32 a passage also serving as a first-floor portion, and 33 a parapet.
[0050]
Apart from the purpose described above, the bioreactor can be used simply as a volume reducer. In that case, it will be a completely waterproof type, and it will be charged with biomass such as metal, tableware and plastics that are not decomposed by highly thermophilic bacteria, and will react for at least 30 days. The volume can be reduced to 1 or less. As this quantity is small, there is no need to dispose of it every day, and it becomes easy to dispose of it. I think it is effective.
[0051]
In this case, if the temperature of the bioreactor decreases due to supply air, such as in the winter, when the temperature of the bioreactor decreases, it can be dealt with by increasing the capacity of the heating device. It is effective to perform the exchange, and since the drain generated at that time is distilled water, it can be discharged as it is.
[0052]
In addition, as a measure against insects, a fine net that prevents small flies from passing through the opening is provided, and as a measure against cats, guarding with a wire net etc. prevents catching spilled garbage, or winter bio This is a measure such as preventing warming on the reactor.
[0053]
It is also possible to intermittently open the outlet and remove the reduced garbage, etc., but as described in the drawing of the application specification on June 15, 2001, the overflow cell is always treated with an increase in contents. When the finished portion overflows, it is possible to facilitate the disposal process.
[0054]
【The invention's effect】
As explained above, the greenhouse equipped with the bioreactor of the present invention is activated while fertilizing biomass that has conventionally only been disposed of, such as garbage, by activating highly thermophilic bacteria present in the soil. In addition to the effect that the heat and carbon dioxide gas that can be used for heating the greenhouse and the growth of plants, it can contribute to the formation of a recycling-oriented society that will be increasingly demanded in the future.
