- a heat medium is accommodated between the outer container 12B and the inner container 12A. In the present embodiment, hot water is used as the heat medium.
- the methane fermentation system 1 is provided with a treatment product circulation section 60 that circulates the treatment product by the pump 63 by taking out the treatment product from the methane fermentation tank 13 and returning it to the inside. Further, the methane fermentation system 1 is provided with a heat medium circulation unit 61 that circulates the heat medium by taking out the heat medium (water) from the solubilization tank 12 and returning it to the inside.
- the heat exchanger 62 is provided with a processed product pipe that is a part of the processed product circulation unit 60, and a heat medium pipe that is a part of the heat medium circulating unit 61 is covered around the processed product pipe.
- Each pipe is formed of a material having high thermal conductivity, for example, copper.
- Heat exchange is performed between the processed material piping and the heat medium piping.
- the processed product warmed by the heat medium returns to the methane fermentation tank 13, and further methane fermentation is performed at a temperature with high fermentation efficiency.
- the temperature of the processed product fermented in the methane fermentation tank 13 is kept uniform, and is maintained so that the methane fermentation efficiency by the fermenting bacteria does not decrease.
- facilities for generating methane gas from organic waste such as the solubilization tank 12 and the methane fermentation tank 13 are accommodated in the containers 2 and 3. Yes. For this reason, since the equipment for generating methane gas can be transported to various places, it is easy to move and the degree of freedom of the equipment place can be increased.
- the temperature of the processed material accommodated in the methane fermentation tank 13 is kept constant with the heat
- FIG. it is not necessary to provide a hot water storage tank for storing hot water for keeping the temperature of the methane fermentation tank 13 constant, so that the entire system can be downsized.
- Such a device further facilitates the movement of the system.
- the hot water heated in the solubilization tank 12 is used as a heat medium so that the processed product stored in the methane fermentation tank 13 is maintained at an appropriate temperature.
- the container 4 The processed material stored in the methane fermentation tank 13 may be maintained at an appropriate temperature by using heat generated by the gas engine 51 that generates power in the power generation facility 4 ′.
- the present invention can be used for the production of methane gas in biomass power generation or the like.
