Description

  The present invention relates to a garbage processing apparatus that decomposes garbage with microorganisms, and more particularly to a garbage processing apparatus that can generate power using heat generated during processing.

The garbage processing apparatus is mainly classified into a heat drying type and a microbial decomposition type. Among these, the microbial decomposition type garbage processing apparatus is one in which microorganisms introduced together with the garbage into the garbage storage unit decompose the garbage (for example, see Patent Document 1). In this case, since the garbage is decomposed while being fermented, there is an advantage that the treated garbage can be recycled as an organic fertilizer.

When air can flow to the other end side (chimney 30 side), it is not necessary to provide a blower in particular.

  In addition, a power storage unit 4 is provided at a lower part on the other side of the housing 20 of the garbage processing unit 2. The power storage unit 4 is configured to store part or all of the power generated by the power generation unit 3. The garbage processing apparatus 1 is driven by power supplied from an external power source (not shown), but a part of power from the external power source may be stored in the power storage unit 4. The power storage unit 4 is connected to an oxygen enrichment unit 5 described later, and supplies driving power thereto. The oxygen enrichment unit 5 is directly supplied with electric power from an external power source.

  An oxygen enrichment unit 5 is disposed on the other side of the housing 20 of the garbage processing unit 2 and above the power storage unit 4. The oxygen enrichment unit 5 is placed in a box-shaped case 50. An oxygen-enriched membrane unit (not shown) is accommodated. An air intake port (not shown) that communicates the inside and the outside is provided on the side surface of the case 50, and the air taken in from the air intake port passes through the oxygen-enriched membrane unit, so that the oxygen concentration is high. It becomes enriched air. Since many products are known for consumer and industrial use, this oxygen-enriched membrane unit can be configured using such commercially available products.

  The side of the case 50 on the side of the garbage processing unit 2 is provided with an oxygen-enriched air inlet 50a communicating with the inside of the casing 20 of the garbage processing unit 2, and is generated by the oxygen enrichment unit 5. Part or all of the oxygen-enriched air is supplied into the housing 20 of the garbage disposal unit 2 through the oxygen-enriched air inlet 50a.

It is supposed to be removed. The odor removing unit 6 may be provided with a driving device such as a fan in order to take in the odor to be removed. In that case, a part or all of the driving power of the driving device is generated by the power generation unit 3. It may be covered by electrical energy.

  Next, the operation of the garbage disposal apparatus 1 as described above and the usage mode of the oxygen-enriched air generated by driving the garbage disposal apparatus 1 will be described with reference to the flowchart shown in FIG. First, garbage is thrown into the housing 20 of the garbage processing unit 2 through the insertion port 20b (S1), and this garbage is accumulated on the shelf 20e in the housing 20. The accumulated raw garbage is decomposed by a predetermined microorganism that is an aerobic bacterium previously placed in the housing 20 (S2), and finally converted into organic fertilizer (S3) from the outlet 22c. It is taken out.

  Garbage that is decomposed by microorganisms ferments and emits an odor. This odor is absorbed and reduced by the odor removing unit 6 (S4). Moreover, heat is generated with the fermentation of the garbage (S5). This heat is about 60 to 80 degrees in the case of a general type of microorganisms used for the decomposition treatment of garbage, and thereby the air in the vent pipe 33a is heated (S6), and the air is blower Is carried into the chimney 30 (S7).

  Since the air heated in this way has a small density and is light, it is easily carried upward, and an upward airflow is generated in the chimney 30 (S8). This updraft rotates the wind turbine of the wind power generator 31 provided on the upper part of the chimney 30 to generate electric energy (S9). The generated electrical energy is stored in the power storage unit 4 together with the electrical energy generated by the auxiliary generator 32 provided at the top of the chimney 30 (S10) (S11). The remainder of the generated electrical energy is used to drive the garbage disposal apparatus 1 and is supplied to various accompanying electrical or mechanical devices.

  For example, such electric energy is supplied to the oxygen enrichment unit 5 to drive it (S12). When the oxygen enrichment section 5 is driven, outside air is introduced from an air intake (not shown), and oxygen enriched air is generated (S13). A part of the oxygen-enriched air is supplied into the housing 20 (processing space 25) of the garbage processing unit 2 through the oxygen-enriched air inlet 50a (S14). The aerobic bacteria in the housing 20 are activated by obtaining oxygen-enriched air (S15), and efficiently decompose garbage. If supply of oxygen-enriched air into the processing space 25 and supply of air from the inlet 20b by opening and closing the inlet lid 21 are sufficient, supply of air from the air inlet 20d is not necessarily required. Absent.

  Further, the remainder of the oxygen-enriched air is discharged to the outside through the oxygen-enriched air discharge port 50b. The discharged oxygen-enriched air can be used for various purposes (S16). For example, it can be used for soil improvement on a farm (S17), for supplying oxygen into water at a fish farm (S18), and for supplying to an O2-rich space including a retreat room of a hospital (S19). . As described above, when used in facilities such as farms, farms, and hospitals, garbage such as grains and fish feed and leftovers are left in each field. The oxygen-enriched air generated by the electric energy obtained by using the electric energy may be used as described above. As a result, the place where garbage is generated and the place where oxygen-enriched air is supplied are the same, so it is not necessary to carry garbage from a distance, and it is necessary to carry oxygen-enriched air to another place. Nor.

  In this case, a ventilation duct (not shown) may be extended from the oxygen-enriched air discharge port 50b of the garbage processing apparatus 1 to a desired location. For example, when used in a hospital, an existing air supply duct may be used in a building, and the space between the oxygen-enriched air discharge port 50b and the closest air supply duct may be connected by a ventilation duct.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a garbage processing apparatus that can also generate power using fermentation heat generated from the garbage being processed. Moreover, it can apply to the garbage processing apparatus which can drive the electrical / mechanical equipment which accompanies using the obtained electric power.

It is a perspective view which shows the external appearance of the garbage processing apparatus which concerns on embodiment of this invention. It is a flowchart which shows operation | movement of the garbage processing apparatus shown in FIG. 1, and the utilization aspect of the oxygen enriched air produced | generated by the drive of this garbage processing apparatus.
