Summary of the invention
It is a kind of easy to operate that the purpose of this utility model is to provide, and can continue air feed, can keep the controlled constant voltage gas storage of constant air feed methane-generating pit by automatic pressure regulation.
The controlled constant voltage gas storage of the utility model air feed methane-generating pit comprises fermentation vat 1, gas storage pond 2 and air feed pond 3; It is characterized in that top, fermentation vat 1 side is provided with opening for feed 7, the bottom is provided with slag-drip opening 8, and the position of the corresponding slag-drip opening 8 in top is provided with service ports 10; Fermentation vat 1 and gas storage pond 2 are separated by divider wall 4, and at least two separate fermentation vats 1 and gas storage pond 2 are communicated with by water seal mouth 5; 2 tops, gas storage pond were connected through communicating pipe 6 and air feed pond 3, and the below, side is provided with the drinking-water pipe 13 that is connected; Air feed pond 3 inner back-offs have the top to set out the constant voltage keg float 14 of gas port 15 and pressure control piece 16; Pressure control piece 16 is connected with balancing weight 19 by joining rope 18 through two fixed pulleys 17.
Further, described fermentation vat 1 inner bottom part is low, high inclined-plane, slag-drip opening 8 places all around.
Further, described gas storage pond 2 inner bottom parts are and are communicated with low, high inclined-plane, drinking-water pipe 13 places all around.
Further, described opening for feed 7 is set to the charging of hydrocone type water-lute.
Further, described slag-drip opening 8 is provided with stopper 9 with matching, and stopper 9 is connected service ports 10 by rope.
Further, described service ports 10 is provided with the maintenance flap 11 through sealing-ring 12 sealings.
The controlled constant voltage gas storage of the utility model air feed methane-generating pit mainly is to recycle by a plurality of fermentation vats 1 to guarantee the without interruption of tolerance in the gas storage pond 2; Again by constant voltage keg float 14, pressure control piece 16 and fixed pulley 17 in the air feed pond 3 with join rope 18 effect and really accomplish constant pressure air feeding; And between fermentation vat 1 and gas storage pond 2, adopted 5 sealings of water seal mouth and isolation relatively, and in gas storage pond 2 and air feed pond 3, all adopt the clear water sealing, improved the security and the reliability of total system; Also can well be fused in the middle of city resident's the living system,, come to facilitate for the city resident in conjunction with the transformation of septic tank; Its beneficial effect is, and is reasonable in design, simple in structure, can continue air feed, automatic Regulation, and easy to operate, with low cost, adaptability is strong.
