Description of drawings

This accompanying drawing is the structural representation of utility model embodiment.

Embodiment

Below in conjunction with description of drawings the utility model embodiment is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.

As shown in drawings, a kind of anaerobic ferment devices provided by the utility model is the multi-cavity body structure, comprise an adjusting chamber that has piston 7, piston chamber 8, electric heating panel 12 and heat absorbing coating 13 to constitute, at least one reaction chamber 1, sealing cover 3, sorbent material 2, common air chamber 4, ventilation arm 5, ventpipe valve 6, be communicated with house steward 9, be communicated with arm 10, communicating pipe valve 11.

Concrete using method is as follows:

1) when reaction chamber all as the dress liquid situation of methane phase container

Before feed liquid is injected reaction chamber, the reaction chamber that the sorbent material 2 that is adsorbed with lipid acid is put into and fix after, cover 3, the second steps of sealing cover, open the valve 6 of the arm 5 of respectively ventilating, close the valve 11 that is communicated with house steward 9, in reaction chamber 1, inject the liquid material, contact when liquid level is increased to sorbent material 2 by the feed liquid input terminus, biological desorption begins, methane just can generate, and dress is after liquid finishes, and closes communicating pipe valve 11.

2) when the dress liquid situation of reaction chamber part as acidifying phase container

According to needing, before feed liquid is injected reaction chamber 1, need open as ventilation arm 5 valves 6 of the reaction chamber 1 of acidifying phase container, connected component tube valve 11 as the reaction chamber 1 of acidifying phase container is closed, and this reaction chamber 1 promptly can be used as acidifying phase container, meanwhile, all the other are closed as the valve 6 of the ventilation arm 5 of the reaction chamber 1 of non-acidizing phase container, common air chamber 4 valve 6 is closed, and is communicated with house steward 9 and closes towards the valve 11 of piston chamber 8, and these reaction chambers 1 are as methane phase container.Under above-mentioned state, import acidizing fluid from the feed liquid input terminus toward container, after input finishes, close the valve 6 of ventilation arm 5 of the reaction chamber 1 of acidifying phase container, open the valve 6 of ventilation arm 5 of the reaction chamber 1 of methane phase container then, carry out the feed liquid input of methane phase container, use step) with situation 1, open the valve 6 of ventilation arm 5 of the reaction chamber 1 of acidifying phase container then, close the sealing cover 3 of acidifying phase container.

3) adjusting of gas generating amount and air pressure

3.1) adjusting by force of gas generating amount and air pressure:

Open the valve 11 and the valve 11 that is communicated with house steward 9 of the connection arm 10 of selected reaction chamber 1, the valve 11 of the connection arm 10 in remaining reaction chamber 1 is closed, suction function by piston 7, bacterium liquid in the selected reaction chamber 1 is transferred to piston chamber 8 by force, close the valve 11 of the connection arm 10 of this reaction chamber 1 then.Bacterium liquid enters into piston chamber 8, and liquid level descends in the selected reaction chamber 1, reduces with the sorbent material contact surface, and the tolerance growing amount reduces thereupon, and air pressure amplification is slowed down, and the atmosphere storage space in this reaction chamber 1 increases simultaneously, and air pressure reduces.Need increase gas production rate again, only need bacterium hydraulic pressure in the piston chamber 8 is returned former reaction chamber 1, and close the valve 11 of the connection arm 10 of this reaction chamber 1, stop bacterium liquid to be back to former reaction chamber 1 and get final product.

3.2) other approach

Guaranteeing under the safe situation, also can directly directly inject bacterium liquid or acidizing fluid, regulating gas production rate and air pressure by direct adding or minimizing sorbent material by seal.

4) heating

Can also can under the situation that meteorological conditions allows, absorb sunlight by heat absorbing coating the liquid material is heated by the electric heating panel energising of regulating the bottom, chamber is heated.

This device also can be used for the occasion of other anaerobically fermentings, is not limited only to the production of methane.
