てそこにガスが蓄えられる。 In recent years, when pig farms are operated in areas with densely populated areas, problems such as bad odors and water pollution tend to occur. In particular, processing of excrement and urine accounts for the majority. A methane fermentation system has recently been developed as a treatment method. This system is schematically constructed as shown in FIG. In FIG. 1, reference numeral 1 denotes a fermenter, into which waste such as livestock manure is injected through an inlet 2. In FIG. Waste is fermented in the fermenter 1, and methane gas is generated therein. The gas is led to a blower 4 and a water drain tank 5 through an outlet path 3.
The gas guided to the blower 4 is supplied into the fermenter 1 for internal stirring. On the other hand, the gas led to the water removal tank 5 is introduced into the desulfurization tank 6 after moisture is removed there. This desulfurization tank 6 is for removing H 2 S, which is an unnecessary component in the gas. The gas from which the H 2 S component has been removed is supplied to a gas holder (not shown), and the gas is stored there.

が出来ない欠点があつた。 It was said that a methane fermentation system having the configuration shown in Figure 1 above would have to be a large-scale system in order to be economically viable. For pig farmers to utilize the above-mentioned system, the cost of the equipment is often too high and it is often economically disadvantageous. The reason for this is that a large amount of oil and electric energy is consumed for lighting the pigpen, floor heating for piglets, etc. In particular, pig pens usually consist of 200 to 300 pigs, and five pig pens are required to fatten 1,000 pigs. For this reason, the use of the system shown in Figure 1 is disadvantageous from the economic point of view as described above, and the construction of the system requires a fermentation tank,
Since the water drainage tank, desulfurization tank, etc. were installed separately, there was a drawback that construction work such as piping between these tanks could not be completed in a short period of time.

It is an object of the present invention to provide a methane fermentation device that can shorten construction time and reduce electrical energy consumption by being equipped with a generator.

にまでコストを低減できる。 The solid separated product obtained by the screw press 13 and the waste liquid from the fermentation tank 15 are produced in an amount of 5 m 3 /month, and since the waste liquid contains an appropriate amount of organic matter that is easily absorbed by plants, it can be used as fertilizer. It can be used in fields, and any surplus can be sold as mixed fertilizer (compost). In addition, in the device of this invention, a screw press 13 and a fermenter 1 are provided in the housing 22.
5. Houses the drain tank 17, desulfurization tank 18, blower 19, gas engine generator 21, etc., and if these are assembled in advance, all that is required is to install the casing 22 on site, which simplifies the construction work. be able to. As a result, the cost, which was conventionally 40,000 to 60,000 yen per pig, can be reduced to 10,000 yen per pig with this device.

とする熱量が得られる利点がある。 Furthermore, since a gas engine generator 21 is used, approximately 1/2 of the total electricity required for lighting and power in pigpens, etc.
In addition to being able to cover the above, 40% of the heat value of the gas engine exhaust gas can be recovered as hot water, so compared to the conventional method where the digestion tank was heated with a boiler, this device alone can heat the digestion tank. It has the advantage of providing the necessary amount of heat.
