Accompanying drawing explanation
Fig. 1 is wherein a kind of structural representation of embodiment of the utility model.
In figure, be labeled as: 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 utility model is further illustrated.
As shown in Figure 1, the utility model methane-generating pit positive-pressure protecting device, 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, on water shoot 11, be 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 holes 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, combustion flame fluctuation is large, is difficult to operation, and air pressure is when excessive, all can have security implication to methane-generating pit 4 and biogas user 6.
The utility model is by the interior buffer pocket 2 that arranges of Storage water tank 1, and Storage water tank 1 regulates the height of Storage water tank 1 interior water level by water shoot 11; Inlet pipe 3 stretches into buffer pocket 2, and inlet pipe 3 the other ends connect biogas pipeline 5, and in the time that the pressure in methane-generating pit 4 increases, 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 larger, the water in Storage water tank 1 can be gone out, can not steady pressure, also need in Storage water tank 1, to add water endlessly simultaneously, waste water resource.The utility model has determined the control to methane-generating pit 4 or biogas pipeline 5 pressure to the control of the interior water level height of Storage water tank 1.Therefore, the utility model device can simply be controlled the pressure in methane-generating pit 4 or biogas pipeline 5, guarantees that pressure is in the scope of a controlled safety.The utility model device is not only simple in structure, cheap for manufacturing cost, and easy to use.In use, directly inlet pipe 3 is communicated with biogas pipeline 5, then in Storage water tank 1, adds water as required.While passing through Storage water tank 1 due to biogas, can take many water vapors out of, water level can decline automatically, and the water vapour of taking out of is uncontrollable, therefore, the utility model also provides a kind of easier working method: how much water vapour of taking out of per hour when first general estimation biogas pressure is maximum, then by running water pipe make up water as required endlessly, control water level by switch pair water pipe 11, when biogas pressure hour, water from running water pipe is directly discharged by water shoot 11, like this can be easier by biogas pressure control within the specific limits.
