<p>PURPOSE:To raise the purity of fuel gas components in fermentative gas, by arranging a fermenting vat for anaerobically fermenting kitchin stuff and a cover for reserving fermentative gas obtained from the fermenting vat, and attaching a carbonic acid gas-permeating membrane to the reservoir. CONSTITUTION:A kitchin stuff disposer is constructed by an upper-opened bottom-closed cylindrical fermenting vat 1, in-vat liquid 2, a kitchin stuff-charging opening 3 connected to the lower part of the periphery of the fermenting vat 1, an annular trap 4 formed around the periphery of the fermenting vat 1, sealing water 5 in the trap 4, an overflow channel 6, a gas-discharging line 7 whose one end is opened to a closed space 8, an upper-closed bottom-opened cylindrical cover 9 to cover the upper portion of the fermenting vat 1 and to form the closed space 8, and a carbonic acid gas-permeable membrane 10 attached to the notched part of the cover 9. By this disposer, methane gas content in the fermenting gas can be raised to 70-90% or so.</p> |
