Abstract

PROBLEM TO BE SOLVED: To achieve storage of devices for putting in of raw materials, methane gas fermentation, organic fertilizer production for each raw material, and gas generating in a container, in which a dissolver is one tank, and fermentation tanks are small plural tanks for each raw material for downsizing of the devices for methane gas fermentation and organic fertilizer production.SOLUTION: Provided is the mobile methane gas fermentation generating device characterized in that: the dissolver and fermentation tanks for methane gas production are provided individually; the dissolver is one unit and the fermentation tanks are small plural tanks (about 5 units); it is possible to produce an organic fertilizer for each raw material; and a whole body including the generating device is downsized and stored in the container and is capable of being moved.

Description

The present invention relates to a movable methane gas fermentation apparatus, a raw material-specific organic fertilizer production apparatus, and a power generation apparatus.

A methane gas fermentation apparatus usually generates methane gas from livestock manure, garbage, etc., but in the manufacturing process, there are only large facilities and no small mobile devices.

The remaining contents produced from methane gas are used as high-quality organic fertilizers, but there is no device for producing organic fertilizers for each raw material in one production plant.

The present invention provides a methane gas fermentation apparatus, a power generation apparatus using the produced methane gas, and a plurality of organic fertilizer production tanks for each raw material in a 40-foot container, as a demonstration machine for disseminating the methane gas fermentation power generation apparatus, and as a learning material. It is provided as an emergency emergency energy generator.

Large tanks are required for dissolution tanks and fermentation tanks for producing methane gas, and there is a limit to downsizing the entire facility, and no container-type methane gas fermentation power generation equipment has been manufactured.

      The problem to be solved is that a large tank is required for the dissolution tank and fermenter for producing methane gas, and it is difficult to reduce the size of the entire facility. And a device for installing all gas power generation equipment in a container has not yet been provided.

    The present invention has separate dissolution tanks and fermenter tanks for optimum conditions for methane gas production, one dissolution tank, and a plurality of small fermentation tanks (about 5), enabling the production of organic fertilizer by raw material. The main feature is that the entire tank can be reduced in size by a small tank and can be stored and moved in a container.

  The mobile methane gas fermentation power generation device of the present invention is a methane gas fermentation power generation device that can be moved to store methane gas production and raw material-specific organic fertilizer by making various raw materials, miniaturize the plant that can generate power using methane gas, and store it in a container. It is also effective for disseminating and learning materials, and securing energy in emergency situations.

To reduce the size of the methane gas fermentation and organic fertilizer production equipment, one dissolution tank and multiple fermentation tanks for each raw material are used to store the methane gas fermentation, organic fertilizer production for each raw material, and a set of gas power generation equipment in a container. Realized.

Raw materials for producing methane gas, livestock manure and garbage are put into the slurry machine 11 without mixing raw materials.

The raw material in the form of a slurry is sent to the dissolution tank 12 and slowly stirred rightward several times a day by the stirring blade 13 and then sent to the fermenter 19 when carbon dioxide gas and ammonia gas are not emitted.

In order to maintain the pH of the dissolution tank at 4.5 to 5.0, active water is automatically sprayed in a timely manner by the Ph controller 49.

As shown in FIG. 3, the stirring blades are inclined to the lower blades and turned to the right so that the contents at the bottom of the tank are lifted up to promote dissolution and fermentation.

The ammonia gas is deodorized by the deodorizer 24 and released to the atmosphere.

When the pressure rises for some reason in the dissolution tank, the pressure is exhausted by the safety valve 25.

In the fermenter 19, methane bacteria are introduced, and the stirring blade is slowly turned to the right several times a day to advance the fermentation.

In order to stabilize the fermentation, the temperature in the fermenter is set to the optimum temperature by the hot water heater 32 using the exhaust heat of the generator 31.

The active water valve 44 is controlled by the Ph controller 50 in order to secure the Ph6.5 to 7.5 in the fermenter by the Ph measuring device 38 installed in the fermenter, and the active water is automatically sprayed from the shower 57 into the fermenter. .

When methane gas is generated and the amount of gas raised in the upper tank 67 of the fermenter is observed, power is generated as fuel of the gas power generation device 31 through the desulfurization device 62 for removing hydrogen sulfide at an appropriate time.

When the pressure increases for some reason in the fermenter, the pressure is exhausted by the safety valve 26.

The upper tank is offset by a plurality of (odd number) guide rollers 63 installed in the lower tank to prevent the tank from falling.

The liquid and precipitate in the fermenter after generation of methane gas is sent from the bottom of the fermenter to the individual / liquid separator 64 by a pump.

The individual / liquid separation tank 64 is allowed to stand still, a precipitant is added, and the supernatant is sent to the liquid fertilizer tank 65 and the individual is sent to the dryer 66.

When the liquid fertilizer tank 65 is filled, the liquid is sent to the active water tank 55. Tap water is automatically replenished so that the active water tank 55 is always filled.

Individual items are rotationally dried by a dryer 66 and are produced as organic fertilizers according to raw materials. The fuel for the dryer uses methane gas.

Since the dry granule fertilizer for each raw material is produced by the rotary dryer 66, the organic compound fertilizer can be produced.

A replaceable activated carbon louver with built-in replaceable activated carbon is installed at the top of the container to replace the activated carbon in a timely manner and prevent the spread of odors to the surroundings.
