Abstract
The utility model relates to a water cycle system for marsh gas pool, which is characterized in that the cycle system comprises a water feeding device, an effluent device and an outer circulating tube. The water feeding device is formed by connecting a straight pipe with a Z-shaped pipe and the lower end is fixed on the bottom of a gas-store pool and communicated with the gas-store pool. An opening on the upper end of the straight pipe is in a feed opening and a one-way stop valve is arranged on the lower end. The upper end of the stop valve is connected with the Z-shaped pipe. The effluent device mainly comprises a straight pipe with the lower end arranged on the bottom of the gas-store pool, and a one-way stop valve is arranged on the lower end of the straight pipe. The opening on the upper end of the straight pipe is arranged in a discharge opening. The outer circulating tube is communicated with the inlet opening and the discharge opening. The utility model has the advantages of enabling the fluid in the pool to automatically circulate, improving the circulation in the bottom of the pool, enabling the straws to sufficiently ferment, utilizing the raw materials fully, reducing the scum in the pool, preventing the marsh gas from falling towards the bottom, avoiding the incrustation and increasing the gas production greatly.
Description
Technical field: the utility model relates to a kind of water circulation system that is used for methane-generating pit.
Background technology: methane-generating pit is used very extensive in vast rural area, and it mainly is to adopt construction method, builds gas storage pond and input and output material passage underground building, input and output material inconvenience, and the water in the gas storage pond can only enter discharge port by tapping channel, can not reflux, and back and forth uses; And often fermentation is not thorough in the gas storage pond, easily produces scum silica frost and causes occurring duricrust, influence factor of created gase, inconvenient maintenance especially, and the cost height, lack work-ing life.
Summary of the invention: the utility model is in order to solve the problem that present methane tank gas production rate is low, maintenance is difficult, work-ing life is short, a kind of water circulation system that is used for methane-generating pit is provided, it is characterized in that: the described recycle system comprises water feed apparatus, discharging device and outer circulating tube, described water feed apparatus is to be formed by a vertical pipe and " Z " type pipe coupling, the lower end is installed in bottom, gas storage pond and communicates with it, described vertical pipe upper end open is positioned at opening for feed, the bottom is provided with unidirectional stop valve, at described stopping valve upper end and described " Z " type pipe coupling; Described discharging device mainly is made of the vertical pipe that a lower end is installed in gas storage pond bottom, and described vertical pipe lower end is provided with unidirectional stop valve, and upper end open is positioned at discharge port; Described outer circulating tube is communicated with the charging and discharging mouth.Adopt this recycle system can make the liquid automated cycle of methane-generating pit, make that straw fully ferments in the pond, thereby reduced scum silica frost in the pond, avoided the duricrust appearance, improved gas production rate greatly.
Description of drawings: Fig. 1, the water circulation system user mode structural representation front view of this methane-generating pit;
Fig. 2, the water circulation system user mode structural representation side-view of this methane-generating pit.
Embodiment: as shown in Figure 1, 2, this water circulation system that is used for methane-generating pit comprises water feed apparatus 4, discharging device 5 and outer circulating tube 6, water feed apparatus 4 is to be formed by connecting by a vertical pipe 7 and one " Z " type pipe 8, the lower end is installed in 2 bottoms, gas storage pond and communicates with it, vertical pipe 7 upper end open are positioned at opening for feed 1, the bottom is provided with pressure valve 9, is connected with " Z " type pipe 8 in pressure valve 9 upper ends, and " Z " type pipe 8 openings are positioned at 2 tops, gas storage pond; Discharging device 5 mainly is made of the vertical pipe 10 that a lower end is installed in 2 bottoms, gas storage pond, and vertical pipe 10 lower ends are provided with pressure valve 11 and guarantee the water only export but no import, and upper end open is positioned at discharge port 3; Outer circulating tube 6 is communicated with opening for feed 1 and discharge port 3.Vertical pipe 7 when material enters water feed apparatus 4 from opening for feed 1 under the effect of pressure valve 9, enters gas storage pond 2 through " Z " type pipe 8.When the increase of pond internal gas pressure, the pressure valve 9,11 on both sides is opened, and water flows out to opening for feed and discharge port from vertical pipe 7,10; When the reduction of gas storage pond 2 internal gas pressures, pressure valve 9,11 is closed, and the water of discharge port 3 enters opening for feed 1 through outer circulating tube 6, is undertaken by the charging program through water feed apparatus 4 again.For the water resources of more abundant reasonable use discharge port, can on discharging device, increase by a compressed water generation apparatus 12 water is sent, connect external pipe, be used to wash lavatory, pigsty etc., and then enter opening for feed and circulate; Simultaneously, in order to make the slag charge that is deposited at the bottom of the pond fully ferment, avoid precipitation too much and cause gas production rate low, can also increase the pipeline 13 in a connection discharge port and gas storage pond, be communicated with compressed water generation apparatus 12 and pipeline 13 by conduit 14 during use, the pressurization of use external force, make water through pipe 10 to compressed water generation apparatus 12, again at the bottom of piping 13 enters the pond, the purpose that reaches the pond bottom cycle and sedimentary biogas is floated.Thus, this recycle system has promptly had three round-robin functions: self circulatory function of methane-generating pit; Be used to wash the cocycle function of lavatory, pigsty etc.; Be used at the bottom of the pond circulatory function under the round-robin.
