Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's wherein a kind of embodiment.
Be labeled as in figure: Storage water tank 1, water shoot 11, buffer pocket 2, venting hole 21, inlet pipe 3, methane-generating pit 4, biogas pipeline 5, biogas user 6.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, Methane tank positive-pressure protector of the present invention, comprises Storage water tank 1, buffer pocket 2 and inlet pipe 3, and the sidewall of Storage water tank 1 is provided with several water shoots 11 vertically, water shoot 11 is provided with valve; Buffer pocket 2 is fixed in Storage water tank 1, the sidewall of buffer pocket 2 and top seal, and the bottom of buffer pocket 2 is provided with one or more venting hole 21, and venting hole 21 is positioned at the bottom of Storage water tank 1; Inlet pipe 3 stretches in buffer pocket 2, and the air outlet area of inlet pipe 3 is less than the total area of venting hole 21.
Those skilled in the art know, and methane-generating pit 4 can produce biogas endlessly, by biogas pipeline 5, biogas are transported to biogas user 6 and use.But due to the impact of factors, in use, the biogas air pressure of supply is unstable, and combustion flame fluctuation is large, is difficult to operation, and when air pressure is excessive, all can there is security implication to methane-generating pit 4 and biogas user 6.
The present invention by arranging buffer pocket 2 in Storage water tank 1, and Storage water tank 1 regulates the height of water level in Storage water tank 1 by water shoot 11; Inlet pipe 3 stretches into buffer pocket 2, and inlet pipe 3 the other end connects biogas pipeline 5, and when pressure increase in methane-generating pit 4, biogas can enter buffer pocket 2 from inlet pipe 3, is then discharged by venting port.If directly inlet pipe 3 is inserted in water, because pressure is comparatively large, the water in Storage water tank 1 can be gone out, can not steady pressure, also need to add water in Storage water tank 1 endlessly simultaneously, waste water resource.The present invention determines the control to methane-generating pit 4 or biogas pipeline 5 pressure to the control of water level height in Storage water tank 1.Therefore, apparatus of the present invention can simply control the pressure in methane-generating pit 4 or biogas pipeline 5, ensure that pressure is in the scope of a controlled safety.Apparatus of the present invention not only structure are simple, cheap for manufacturing cost, and easy to use.In use, directly inlet pipe 3 is communicated with biogas pipeline 5, then adds water in Storage water tank 1 as required.Due to biogas by Storage water tank 1 time, many water vapors can be taken out of, water level can decline automatically, and the water vapour taken out of is uncontrollable, therefore, the present invention also provides a kind of easier working method: elder generation is per hour when probably estimation biogas pressure is maximum takes how much water vapour out of, then by running water pipe make up water as required endlessly, by switch pair water pipe 11 controlling water level, when biogas pressure hour, water from running water pipe is directly discharged by water shoot 11, like this can be easier be controlled within the specific limits by biogas pressure.
