Description

The present invention is an invention that effectively uses food residues and animal excrement. For example, compost is returned to the field in the form of compost, but the reality is that contamination of sawdust is a problem in terms of quality. In the present invention, it is reduced to the field not as compost but as carbonized. The present invention is provided with power generation using an aerobic thermophilic bacterium. The amount of heat generated by microorganisms has enormous energy. The present invention provides an apparatus for generating electricity with microorganisms, animal excrement, plant residues and the like, and a carbonization apparatus that integrate these facilities and provide a continuous treatment system.

The present invention arranges a rotary tank. In this tank, the required number of resistance wings are installed with the inclination of the input material from the inlet toward the outlet. The input slowly moves to the exit with the rotation. In the tank, for example, in the case of compost, high-temperature microorganisms process manure and generate heat of decomposition. The exothermic temperature is a temperature range from 70 degrees to 80 degrees.

Many of the components of the input are sawdust and are discharged without being decomposed. The discharged sawdust component is transported to the next process by, for example, a belt conveyor. The next process here refers to the carbonization equipment. The carbonization device here has a structure that can be sealed inside, and has a shed and a chimney. Furthermore, in order to keep the inside of the furnace at a constant temperature, a structure for spraying liquid is installed. This is a temperature sensor that controls the internal combustion temperature. The target value is in the range of 250 to 500 degrees. However, since this temperature range is the temperature range where dioxins are generated, a buff filter is installed in the smoke stack.

Carbonized char can be reduced to the field. In recent years, the Electricity Business Law has been amended. This is a breakthrough in binary power generation. Binary power generation has a structure in which a turbine and a generator using an incombustible material as a medium at 100 degrees or less are integrated. The structure shall not scatter wings when damaged. For example, ammonia water, chlorofluorocarbon, etc. can be selected as the medium.

JP 2010-90883 A

As a prior art of the present invention, there is the above-mentioned document JP 2010-90883. The drive part in the said invention winds and rotates the stirring blade. In the structure for generating electricity, a flame retardant liquid is vaporized by the fermentation heat of microorganisms in the tank outer body to generate turbine power. The above invention uses the outer periphery of the tank and wind power. This is a problem in efficiency because it is not in direct contact with the substrate by heat exchange. There is a problem that only a small machine can be driven by the wind power of the drive unit. The amount of power generation is also small and limited.
The present invention is a large-scale processing apparatus that achieves high-output power generation and is improved in thermal efficiency.

The problem to be addressed by the present invention is a large amount of manure discharged daily, food residues from factories, and the like. These must be dealt with reliably and a healthy cycle, for example, environmental conservation and warming considerations must be made. In addition, problems such as sanitation due to odor must be considered. In particular, urine needs to be taken into consideration because contamination problems such as water quality occur. Sawdust is commonly used on livestock floors. This sawdust is not suitable for microbial degradation.

In binary power generation, sufficient contact between food and microorganisms is necessary to extract heat efficiently. It is necessary to solve the problems such as a structure in which the turbine and the power generation unit are integrated so that fragments do not scatter when damaged.

In order to solve these problems, the present invention adopts an unprecedented technique. This agitation tank is intended for mass processing. For example, a rotary kiln system having a diameter of 3 m and a length of 20 m is adopted. At the lower part of the outer periphery of the tank, there will be enough rollers to hold the tank, which will be decelerated by a large capacity motor and rotated slowly.

Inside the tank, spiral wings for pit shafts are arranged. It is pushed out to the outside in about one week. Install piping to circulate the flame retardant gas in the center of the interior. A pipe that can discharge compressed air is installed directly below it. This is because the microorganisms are aerobic to prevent oxygen deficiency. A large, medium, and small bowl is placed in the tank so that the air bed can come out so that the fungus bed does not harden further. This is to prevent more air layers and lumps. This further improves efficiency. Inside the pipe, the low-boiling flame-retardant liquid is gasified, becomes a high-pressure gas having a very high vapor pressure, and moves toward the gas turbine as the next step.

The generator and coaxial turbine rotate at high speed and start generating electricity. The circulating gas flows into the cooling section after rotating the turbine. The cooled gas is liquefied by a compressor and pumped to a circulation pipe in the tank. Thereafter, as long as food to be fed on this cycle is provided, the microorganism generates heat of decomposition and operates the system continuously for 24 hours.

Sawdust, etc. discharged from the tank is put into the carbonization device through transportation piping. When a certain amount is manually ignited after charging, carbonization begins. Time depends on its scale. The product after carbonization becomes a valuable product as a high-quality substrate.

The present invention becomes a valuable product by changing compost, which has not been useful in the past, to carbide. Carbide is an effective base material for fields and contributes to soil improvement. Electricity generated by binary power generation can also be used as a profit source by selling electricity. In terms of the environment, the effects of removing bad odors and purifying wastewater are also great. In addition, mixing carbide with the floor is expected to prevent odors and prevent diseases. The use of carbide for the floor also saves money. Moreover, since the carbide is pasteurized at high temperature, it can be used as a mixed feed for food. Carbide has high marketability and is expected to be used in general home centers.
