Description

Technical Field

[0001] The present invention relates to a fermentation treatment tank used for fermenting and composting organic wastes such as agricultural resources wastes, livestock excreta, agricultural village drainage sludge, sewage sludge, food wastes, fishery resources wastes, and woody resources wastes, and particularly relates to a bio-enzyme spraying device used for promoting fermentation and deodorizing the shed.

Background Art

[0002] Conventionally, in the treatment of organic wastes such as livestock excreta and garbage, a method of adding microorganisms to the wastes for fermentation treatment and composting has been widely adopted. In this fermentation treatment method using microorganisms, organic substances are fermented and decomposed by microorganisms to be transformed into organic fertilizers mainly composed of uniform low-molecular compounds.

[0003] For example, Patent Document 1 discloses a method for biologically treating organic wastewater, in which a complex active microorganism group that grows at a high temperature is mixed into the organic wastewater in the first decomposition treatment tank, air is blown in, and the organic wastewater is maintained at a high temperature to grow the complex active microorganism group. Then, biological treatment is carried out in the second decomposition treatment tank, and the separated water from which solids have been separated is subjected to evaporation treatment in an evaporation treatment tank.

[0004] In addition, Patent Document 2 discloses that garbage, cow dung, a moisture regulator, pulverized bamboo charcoal, a fermentation promoter containing effective microorganisms, and bamboo vinegar liquid are sequentially put into a mixing blender device and mixed and stirred to adjust the moisture content to obtain putrefactive organic waste with a moisture content of 55 to 60%. This putrefactive organic waste is first fermented aerobically and anaerobically to 70 to 85°C by an effective microorganism group, and then further fermented aerobically and anaerobically to 50 to 68°C for a second medium fermentation. This intermediate organic fermented product after the second medium fermentation is fermented aerobically and anaerobically at room temperature of 30 to 40°C for a third maturation fermentation to produce a fully matured organic fertilizer.

[0006] However, in order to promote the fermentation of fermenting microorganisms in the above-mentioned organic waste, there has been a problem that heating equipment such as a heater is required. In view of the problems of the prior art as described above, the present invention provides a bio-enzyme spraying device capable of obtaining economical and high-quality compost without separately using heating equipment for promoting fermentation during the composting process of organic waste. MEANS FOR SOLVING THE PROBLEMS

[0007] To achieve this object, the bio-enzyme spraying device of the present invention sucks outside air from an outside air suction port (12a) and Where livestock manure and kitchen waste S are accumulated fermentation tank (11) is provided with a high-pressure blower (1) having a fan (F) of a motor (M) controlled by an inverter that blows air into it, an air supply pipe (15) for warm air exhausted from the high-pressure blower (1), and a return ventilation pipe (16) that bypasses the warm air supply pipe (15) to the outside air suction pipe (12). When the high-pressure blower (1) is started, The said at the time of starting the high-pressure blower (1), Air supply frequency control is performed according to the temperature deviation between the set temperature of the high-pressure blower (1) and the outside air temperature detected by a temperature sensor (not shown) to control the induced ventilation volume, and zone PID (Proportinal Integral Differential) control is performed to raise the temperature of the atmospheric temperature sucked from the outside air suction pipe (12) and send it out as warm air. A tank (10) storing a fermentation-promoting enzyme solution is communicated via an ejector nozzle (7) to an aspirator (8) that creates a reduced pressure state by the Venturi effect, and the is communicated with the high-pressure blower (1) to circulate and raise the temperature of the outside air sucked into it. Hot air ejection pipeline (13) is communicated with a warm air jet pipe ([[]] 13a ) having a warm air jet port ( 13 ) for spraying the fermentation-promoting enzyme solution into the fermentation treatment tank 11. This is the first feature. Also, the inverter control changes the PID value step by step for each rotation frequency band of the motor M. Set temperature for upward air supply of outside air to raise the temperature to 38°C to 40°C preferred by microorganisms in livestock manure and kitchen waste SUntil the temperature deviation reaches -5°C, it operates at 60 Hz in the acceleration operation range, and in the range up to a temperature deviation of ±2°C, it operates at 45 Hz in the steady operation range. The said air supply In the deceleration operation range exceeding the set temperature, it operates at 40 Hz, closes the blower valve (4), and returns and circulates it with the return valve (3). By controlling the blower temperature with an inverter, the blower temperature is increased to about 3 to 4 times the outside air temperature. This is the second feature.

[0008] In the high-pressure blower of the present invention, the inverter uses the heat generated during power conversion From the motor to heat the air. Also, when high-pressure air is injected in a certain direction inside a pipe or nozzle, an ejector nozzle that causes the entire air flow inside the pipe to be pulled in that direction is used to spray the bio-enzyme TM liquid in a mist form and at high pressure.

Advantages of the Invention

[0009] The present invention has the following excellent effects. By spraying the bio-enzyme, the fermentation of the compost in the compost shed can be promoted and the odor can be eliminated. Also, by using a high-pressure blower, closing the blower outlet with inverter control and circulating the air back with a return valve, the blower temperature can be increased to about 3 to 4 times the outside air temperature without separately installing a heat source (such as a heater). Furthermore, by spraying the bio-enzyme TM liquid in a mist form using an ejector method and connecting it to the existing floor blower and piping of the compost shed, the fermentation can be promoted efficiently. As a result, high-quality composting can be achieved in a shorter time even for cold regions or materials with a high moisture content.

Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. Note that this example is applied to livestock manure composting treatment.

Example

[0012] As shown in FIGS. 1 to 3, the bio-enzyme spraying device according to the present invention sucks air from an outside air suction pipeline 12 provided with a filter silencer 9 at a suction port 12a and ejects warm air to livestock manure and kitchen waste (organic waste) S accumulated in a fermentation tank 11. A high-pressure blower 1 is connected to a warm air ejection pipeline 13, a return ventilation pipeline 16 that circulates the outside air sucked into the high-pressure blower 1 and is temperature-increased by inverter control, and a bio-enzyme TM liquid for promoting fermentation is stored in a storage tank 10. It is communicated to an aspirator 8 that creates a reduced pressure state by the Venturi effect via an ejector nozzle 7, and is generally configured to spray the bio-enzyme TM liquid into the fermentation tank 11 from its bottom surface.

[0013] And the high-pressure blower 1 equipped with a fan F of a motor M controlled by an inverter can raise the temperature of the air sucked from the outside air suction pipeline 12 and send it out as warm air. A warm air supply pipeline 15 for the warm air exhausted from the high-pressure blower 1 and a return ventilation pipeline 16 that bypasses this warm air supply pipeline 15 to the outside air suction pipeline 14 are communicated. At the start-up of the high-pressure blower 1, frequency control is performed according to the temperature deviation between the set temperature of the high-pressure blower 1 and the outside air temperature detected by a temperature sensor (not shown) to control the induced ventilation volume. That is, so-called zone PID (Proportinal Integral Differential) control is performed.

[0014] Specifically, the external air temperature is raised to 45°C to 60°C to increase the temperature of livestock manure and kitchen waste (organic waste) S to 38°C to 40°C, which is preferred by the microorganisms therein. The method is to change the PID value step by step for each rotation frequency band of the motor M. For example, until the temperature deviation from the set temperature reaches -5°C, it is set as the acceleration operation range at 60 Hz. The range up to a temperature deviation of ±2°C is set as the steady operation range and operated at 45 Hz. In the deceleration operation range exceeding the set temperature, it is operated at 40 Hz. In the present invention, by closing the air supply valve 4 and returning and circulating it with the return valve 3, the air supply temperature is inverter-controlled. Without separately installing a heat source (such as a heater), the air supply temperature can be raised to about 3 to 4 times the external air temperature (for example, when operating for 20 minutes at an external air temperature of 5°C, it is raised to 60°C).

[0015] In addition, in the apparatus of this embodiment, automatic control is performed via a feedback circuit based on the detection signal of a warm air sensor (not shown), and by these means, the hot air temperature, hot air volume, hot air pressure, etc. can be accurately kept within a certain range.

[0016] Generally, in a drying blower device, since the blower-built-in heater has a certain heat capacity, it is known that when the intake air volume is reduced, the hot air temperature rises, and conversely, when the intake air volume is increased, the hot air temperature drops. Therefore, by adjusting the intake air volume, the hot air temperature, hot air volume, hot air pressure, etc. can be adjusted quickly and easily.

[0017] Also, in the high-pressure blower 1 of the present invention, utilizing the Venturi effect in which when high-pressure air is jetted in a certain direction in a pipe or nozzle, the air flow throughout the pipe is pulled in that direction, it is communicated via an ejector nozzle 7 to an aspirator 8 that creates a decompressed state from a storage tank 10 storing the bio-enzyme TM liquid for promoting fermentation by the Venturi effect, and the bio-enzyme TM liquid can be jetted into the fermentation tank 11 in a mist-like and high-pressure manner.

[0018] In this embodiment, although mainly aiming at composting livestock manure, organic wastes such as food residues and domestic garbage discharged from the market are converted into mature organic fertilizers. As the bio-enzyme TM solution containing organic microbiota, a fermentation promoter containing fungi selected from the bacterial groups belonging to filamentous fungi, bacteria, actinomycetes, etc. may be used. Specifically, the filamentous fungi are selected from the group belonging to Aspergillus, Mucor, Ketomiunu, Fusarium, Milocesium, Trichoderma, etc., the bacteria are bacteria belonging to the group such as Bacillus, Cellulomonas, Corynebacterium, Cytophaga chlorobiium, Propionibacterium, Rhodospirillum, Rhodopseudomonas, etc., and also selected from the bacterial groups or fungi including white wood rot fungi and photosynthetic bacteria, the actinomycetes are selected from the group containing bacteria belonging to Micromonospora, Nocardia, Streptomyces, Corynebacterium, Actinomyces, Streptoverticillium, Rhodococcus, etc., and a plurality of selected types of fungi are mixed and used.

[0019] As shown in FIGS. 4 to 5, as a specific embodiment of the device of the present invention, in a housing 17 with casters 22 for movement attached to the bottom surface, the main components similar to those in Example 1 are accommodated, and on the front side of the housing 17, each measuring instrument such as a thermometer 18, a vacuum gauge 19, and a pressure gauge 20 and an operation panel 21 are arranged and configured.
