Description

A kind of marsh gas pond

Technical field

The utility model relates to a kind of methane-generating pit.

Background technology

At present, biogas has obtained general utilization as a kind of energy-conservation combustible gas.Existing methane pool mainly is to be made with cement casting or glass reinforced plastic, and these two kinds of methane-generating pits are hardware fixed sturctures, make it be not easy to move, and being given a shock back damage easily, influences its original stopping property, and the biogas that leaks out pollutes the environment; In addition, these two kinds of produced by methane-generating pit costs are higher, and in the life-time service process shell of its internal junction, can cause its gas producing efficiency significantly to reduce; In addition, the user needs to carry out in the pond down to these two kinds of methane-generating pit maintenances the time, causes the user to poison because of sucking obnoxious flavour easily, and security is lower.

Summary of the invention

The purpose of this utility model is, provide a kind of being convenient to move, has shockproof function, good seal performance can keep the cleaning of outside atmosphere, can significantly improve gas producing efficiency, cost is lower, store, transport and when safeguarding security higher, the marsh gas pond that work-ing life is long is to overcome the defective of existing methane-generating pit.

The utility model is to constitute like this: it comprises main tank body 1, in main tank body 1, be provided with the software inner bag 2 of a sealing, on software inner bag 2, have opening for feed 3, discharge port 4 and air outlet 5, be provided with water pressure house 6 in main tank body 1 one sides, opposite side at main tank body 1 is provided with feed-pipe 7, opening for feed 3 on the software inner bag 2 is connected with feed-pipe 7, above main tank body 1, be provided with seal cover board 8, on seal cover board 8, be provided with the escape pipe 9 that links to each other with the air outlet 5 of software inner bag 2, on the discharge port 4 of software inner bag 2, be connected with a threeway 10, one end of threeway 10 is communicated with the bottom of water pressure house 6, be connected with on the another port of threeway 10 and take out slag device 11, the slag notch 12 of taking out slag device 11 is located in the storage slag bath 13 on main tank body 1 next door.

In the above-mentioned marsh gas pond, on escape pipe 9, be provided with topping-up pump 14.

In the aforesaid marsh gas pond, between escape pipe 9 and topping-up pump 14, also be connected with master switch 15 and water trap 16, on the delivery port of topping-up pump 14, be connected with desulfurizer 17 and tensimeter 18.

In the aforesaid marsh gas pond, described seal cover board 8 is to be made of waterproof layer, cement plate and thermal insulation layer.

Compared with prior art, the utility model is installed a software inner bag in main tank body, rely on material to fill to form a fermenting space, this soft body structure make its can be behind the emptying material FOLD AND PACK, be convenient to move; The software inner bag is subjected to deformation taking place behind the external pressure, but this deformation can ownly recover, and makes to the utlity model has to a certain degree shockproof function, and do not influence original sealing effectiveness after recovery, and do not have the biogas leakage, can keep the cleaning of outside atmosphere; In addition, the shell of in the life-time service process, in the software inner bag, being tied, can make it fall to fermentation once more in the natural pond liquid in the software inner bag by the mode of extruding and vibrations, the stopping property of adding the software inner bag is better, and the utility model can significantly improve gas producing efficiency; Through test, the software inner bag can bear five kPas interior pressure, makes it safe in storage and transportation; In addition, the utility model uses takes out the slag device and can and be disposed in the storage slag bath the waste residue sucking-off, and the user need not descend in the main tank body and clean, and avoids it to suck obnoxious flavour and poisons, and has improved the security of safeguarding; Production cost of the present utility model is lower, only is 2/3rds of the methane-generating pit made of cement casting or glass reinforced plastic; Besides, the natural pond liquid meeting extrusion soft inner bag in the water pressure house of the present utility model promotes software inner bag pressure inside, and topping-up pump is installed outside main tank body, can press sucking-off biogas under the insufficient situation in main tank body, has guaranteed that people can use biogas constantly.
