Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a gas boulder used in a waste treatment device, particularly a device for generating methane gas from livestock manure, etc.

[Prior art and its problems]

BACKGROUND ART Many devices have been proposed and put into practical use as means for collecting and fermenting livestock manure containing organic matter from pigs, cows, chickens, etc. and generating methane gas. For example, the apparatus shown in FIG. 1 connects a separator 0, a liquefaction fermentation tank 12, a gasification fermentation tank 14, and a gas holder 16, respectively, and uses the methane gas stored in the gas holder 16 as city gas or for power generation. used as fuel for Furthermore, the example of the device shown in FIG.
2 is connected to a methane fermentation tank 20 integrally provided with a methane fermentation tank 22, and methane gas is extracted from the methane gas boulder 22 as fuel.

In the conventional device mentioned above, various measuring instruments are used to detect the amount of gas stored in the bag-shaped gas boulder, but there is a large error between the measured value and the actual amount of gas remaining. Furthermore, it is difficult to forcefully discharge the residual gas in the gas holder.

In order to overcome the above-mentioned difficulties, the applicants made numerous improvements, and as a result, the gas holder was roughly divided into two by a partition membrane to form two partition chambers, and one partition was placed on the methane gas supply and discharge side. By configuring the other partition chambers to communicate with the pressurized gas supply and discharge side, gas can be discharged smoothly and completely from within the gas holder, and the position of the partition diaphragm can be controlled from the outside. It was found that the amount of methane gas contained in the gas boulder can be accurately determined by visual inspection.

[Purpose of the invention]

Therefore, the general object of the present invention is to provide a methane gas generation device comprising a methane gas generation tank and a gas holder.
To provide a simple gas holder which stores generated methane gas and always discharges gas at a predetermined pressure in a circle lfX, and which allows the amount of gas accommodated in the holder to be accurately visually confirmed.

[Key points of the invention]

In order to achieve the above object, the gas holder of the methane gas generator according to the present invention includes a gas generation tank for fermenting wastewater containing organic matter to generate methane gas, and a check valve and a pressure regulator for this gas generation tank. and a gas holder communicated through a provided piping, the partition membrane being moved so as to substantially cover approximately 1/2 of the inner wall surface of the gas holder when the gas is stored at maximum and minimum on the inner wall surface of the gas holder. A first partition chamber which can be freely provided to supply and discharge generated methane gas, and a second partition chamber which can supply and discharge pressurized gas to the partition diaphragm.
It is characterized by defining a partition room.

The gas holder is made up of, for example, an inner bag made of a soft PvC sheet and an outer bag made of tarpaulin. A partition membrane is attached to the inner wall surface of the inner bag, and locking means of a fixing rope are attached at predetermined intervals along the outer surface of the outer bag. It is vertically installed. Furthermore, the inner bag of the gas holder is made of a transparent material, while the partition diaphragm is made of an opaque material, and a part of the outer bag is provided with one or several viewing windows for viewing the inside of the gas holder.

The second partition of the gas holder is communicated with the pressure regulator and the compressor, so that a predetermined pressure gas is always applied to the methane gas in the first partition.

Other objects and advantages of the invention will become more apparent from the following description. 5 Next, a preferred configuration example of the gas holder of the methane gas generator according to the present invention will be described in detail below with reference to the accompanying drawings.

[Embodiments of the invention]

Referring to FIG. 3, an example of the configuration of a methane gas generation device for processing livestock manure according to the present invention will be described. A sewage tank 24 for separating manure etc. into solids and liquids is connected to this sewage tank via piping 26. A check valve 34 and a pressure regulator 36 are connected to the gas generation tank 28 via piping 32.
It is composed of a gas holder 38 that communicates with the gas holder 38, a pressure regulator 42 and a compressor 44 that supplies compressed gas to the gas holder 38 via piping 40.

Note that an overflow pipe 45 is provided at the upper part of the gas generation tank 28.
is provided to automatically overflow and drain the desorbed liquid in the tank 28.

In FIG. 4, the gas holder 38 of the methane gas generator according to the present invention is composed of a hollow cylindrical inner bag 46 and an outer bag 48 surrounding the inner bag 46. A reinforcing cloth 50 is sewn or attached, and a belt loop 52 is attached to the reinforcing cloth 50, and a belt 54 is inserted therethrough to hold the fixed rope 56.

Referring again to FIG. 3, a partition membrane 5 is provided on the inner wall surface of the inner bag 46.
8 is stretched so as to cover approximately 1/2 of the inner wall surface at maximum and minimum gas storage in the gas holder 38, thereby forming a first partition chamber 60 and a second partition chamber 62 in the gas boulder 38. An inlet 64, a drain 65, and an outlet 66 for the generated gas are opened in one partition, and the second partition 62 communicates with a pressure regulator 42 and a compressor 44 through a pipe 40. The inner bag 46 is made of a transparent material such as a soft PVC sheet, while the partition diaphragm 58 is made of an opaque soft PVC sheet so that its moving position can be clearly discerned from the outside. Peephole 5 in the right place
9 is constructed using a transparent material. Note that there may be a plurality of viewing windows, and the outer bag 48 may be made of a transparent material.

A lid plate (not shown) of the gas generation tank 28 as a fermentation tank has a liquid feed pipe 80 led out from the sewage tank 24, a stirring gas supply pipe 82, a hot water supply pipe 84 for heating, and a pipe connected to the gas holder 38. The air supply pipe 86 is centrally connected, and a drain pipe 88 is led out from the lower part of the gas generation tank 4.

In addition, as shown in FIG. 3, the stirring gas supply pipe 82 is branched from a part of the air supply pipe 86 led out from the gas generation tank 28, and a blower 83 is connected to that part to supply the generated methane gas. The structure is such that a part of the gas is used as a stirring gas.

According to the gas holder of the methane gas generator according to the present invention constructed in this way, the waste water in the sewage tank 24 is fed into the gas generation tank 28 via the piping 26, and the sewage from the sewage tank 24 is fed into the gas generation tank 28 through the heating hot water supply pipe 84. The gas is heated to a temperature in the range of 60° C. and further stirred by stirring gas supplied by a blower 83 from a gas supply pipe 82 branched from the piping 32 to generate methane gas in the upper part of the gas generation tank 28, and this methane gas is sent. When the gas is supplied to the gas holder 38 through the trachea 86 to fill the holder, the partition diaphragm 58 is moved to the position shown in FIG.
It will be understood that all the pressurized gas fed into the second compartment 62 by the compressor 44, which is in close contact with the inner wall of the compartment 62 and thus presses the partition diaphragm 58, is forced out.

Next, when using the gas stored in the gas holder 38, the compressor 44 is operated to transfer the compressed gas to the second partition chamber 62.
When the gas is fed into the first partition, the partition diaphragm 58 is pressed in the direction of the first partition 6°, and the gas at a predetermined pressure is discharged from the discharge port 66. At this time, the moving position of the partition diaphragm 58 can be monitored from the outside through the viewing window 59. The condensed water remaining in the gas holder 38 is drained via the drain 65.

As described above, according to the gas holder of the methane gas generator according to the present invention, the methane gas generated by the gas generator can be smoothly introduced into and discharged from the gas holder, and the capacity of the gas in the gas holder can be reduced. This can be accurately confirmed from the outside, and the gas at a predetermined pressure can be quickly discharged by using a compressor when discharging the used gas.

Although the preferred embodiments of the present invention have been described above, it goes without saying that various design changes can be made without departing from the spirit of the present invention.
