Abstract
The utility model discloses a hydraulic biogas tank, aiming at providing a hydraulic biogas tank with a stable pressure, able to reduce steam and carbon dioxide in biogas and improving calorific value. The utility model is composed of a gas cavity, a hydraulic cavity and water. The top end of the gas cavity is provided with an inlet pipe and an outlet pipe; the lower end of the inlet pipe reaches under the water level; the top end of the hydraulic cavity is provided with a water inlet pipe and an overflow pipe while the lower end is provided with discharge pipe with a valve.
Description
Technical field
The utility model relates to the biogas applied technical field, and more particularly, it relates to a kind of biogas gas tank with hydraulic devices.
Background technique
At present, the air storage mode of rural area and industrial employed biogas mainly contains two kinds, and a kind of is in being stored between the top air storage of hydraulic type biomass pool, to be connected as a single entity with sweathouse.When the air pipe sealing, after fermentation raw material decomposed aerogenesis, biogas constantly increased, and rises between air storage, and gas is many more, and air pressure is big more, and sweathouse liquid level pressure increases, and liquid level descends, and the liquid level of feed space and discharge room rises, and corresponding the obtaining of volume enlarges between air storage.Be opened as air pipe, gas constantly consumes, and sweathouse liquid level pressure reduces, and under the barometric pressure effect, the liquid level of supply pipe and discharge room descends, and the liquid level of sweathouse rises, and volume is corresponding between air storage reduces.This part feed liquid of utilizing is gone here and there back and forth, causes that hydraulic pressure changes the mode of storing and discharging biogas repeatedly and has following shortcoming:
1, air pressure changes repeatedly, and is unfavorable to the smooth combustion of pond body intensity and light fixture, kitchen range;
2, the generation of faults such as removable cover gas leakage and the loss of discharge room zymotic fluid appears easily;
Another kind is the air storage of float cover type gas storage enclosure, and this mode is separated with ferment pool, does not have water pressure chamber, adopts floating cover and supporting water seal tank air storage, has overcome the unstability of hydraulic type biomass pool with atmospheric pressure.But fail to solve following problem: 1, produce in the biogas, carbon dioxide, water vapour content height have had strong inhibitory effects to burning; 2, during discharging, the sweathouse liquid level descends, and the sweathouse space increases and forms negative pressure, and the biogas in the gas storage enclosure is back to sweathouse, so the combustion gas tool can not use during discharging.
Summary of the invention
The utility model has overcome deficiency of the prior art.Provide a kind of biogas pressure that can make stable, can improve methane purity in the biogas again, and water pressing biogas gas tank safe in utilization.
Water pressing biogas gas tank of the present utility model, comprise gas storage chamber, hydraulic pressure chamber, water composition, be provided with dividing plate between described gas storage chamber and the hydraulic pressure chamber, end dissociative under the described dividing plate, make the water in gas storage chamber and hydraulic pressure chamber logical, described gas storage chamber top is provided with suction tude, steam outlet pipe, and the underwater is stretched into a little more than the dividing plate bottom in described suction tude lower end.
Described hydraulic pressure top of chamber is provided with into water, spill pipe, and described suction tude upper end connects biomass pool, and the underwater is stretched into a little more than the dividing plate bottom in the suction tude lower end.
The beneficial effects of the utility model are: (1) biogas pressure is stable; (2) the fire damp purity height of input burning appliance improves combustion heat value; (3) simple in structure, Security is good.
Description of drawings
Accompanying drawing is the structural representation of the utility model water pressing biogas gas tank.
3 dividing plates, 4 suction tude, 5 steam outlet pipes, 6 water inlets of 1 gas storage chamber, 2 hydraulic pressure chambeies, spill pipe 7 waste pipes 8 water 9 valves
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
In the accompanying drawing, be provided with dividing plate 3 between gas storage chamber 1 and the hydraulic pressure chamber 2,3 times end dissociatives of dividing plate, 2 tops, hydraulic pressure chamber are provided with into water, spill pipe 6, from water inlet, inject water 8 in the spill pipe 6, water 8 flows into gas storage chamber 1 from hydraulic pressure chamber 2 through dividing plate 3 lower ends, under the normal pressure, gas storage chamber 1 seals at the fooled steam outlet pipe 5 of same horizontal plane with hydraulic pressure chamber 2 middle water levels, after fermentation raw material decomposed aerogenesis, biogas increased gradually, enters into gas storage chamber 1, gas is many more, air pressure is big more, and when biogas pressure was greater than atmospheric pressure in the gas storage chamber 1, the liquid level in the gas storage chamber 1 descended, liquid level in the hydraulic pressure chamber 2 rises, produced water-head, kept certain pressure owing to hydraulic pressure gas makes the biogas of gas storage chamber 1.When using gas, biogas is from steam outlet pipe 5 output, and the current in hydraulic pressure chamber 2 return in the gas storage chamber 1, i.e. hydraulic pressure chamber 2 drawdown, and gas storage chamber 1 water level rises.Rely on the automatic lifting of hydraulic pressure chamber 2 water levels, the biogas pressure of gas storage chamber 1 can be regulated automatically, keep the fuel-burning equipment stable fire.When aerogenesis was too many, when hydraulic pressure chamber 2 water levels surpassed 2 tops, hydraulic pressure chamber, water 8 is discharged from water inlet, spill pipe 6, and was safe in utilization to guarantee.
The utility model will be put part and be that described suction tude 4 lower ends stretch under the liquid level, the biogas that produces is not directly to feed gas storage chamber 1, but enter in the water 8, produce negative pressure biogas when preventing that biogas pressure is excessive or during the biogas discharging and be back to ferment pool, simultaneously, after biogas enters in the water 8, carbon dioxide is soluble in water, water vapour in the biogas enters in the water to meet and condenses into water after cold, and methane gas solubility in water is minimum, thereby the fire damp concentration that enters into gas storage chamber 1 is improved greatly.Stretch into subsurface suction tude 4 ends and exceed dividing plate 3 bottoms, prevent that a small amount of biogas from entering in the hydraulic pressure chamber 2.
2 bottoms, described hydraulic pressure chamber are provided with the waste pipe 7 of band valve 9, the mouth of pipe that waste pipe 7 connects hydraulic pressure chamber 2 one ends is higher than dividing plate 3 bottoms, and the valve 9 of regular opening water discharge pipe 7 during use is discharged the water 8 in the hydraulic pressure chamber 1, refill clean water, reach capacity to prevent the carbon dioxide that is dissolved in the water 8.
