Abstract

The utility model discloses a cover-bag type methane tank. The utility model is characterized in that the methane tank comprises an open columnar tank body and a press cover on the top of the open column of the open columnar tank body; a plastic liner is arranged in the air chamber on the upper part of the methane tank; the plastic liner is a reverse-buckling gas collecting cover; the hemline of the gas collecting channel is lower than the liquid level inside the tank, and is connected on the side wall of the tank body in a detachable structure. The cover-bag type methane tank solves the leakage problem probably existing in the concrete methane tank as the good gastightness of the plastic liner; the gas collecting channel connected in a detachable structure make the slagging course extremely safe and convenient; simultaneity the construction difficulty is reduced, so the cost of the methane tank is reduced.

Description

Hood bag formula methane-generating pit

Technical field:

The utility model relates to methane-generating pit.

Background technology:

Hydraulic type biomass pool is a kind of concrete structures that is positioned at underground, relies on its concrete layer to seal, and the subject matter of existence comprises:

1, because of causing the situation that biogas leaks, the pool wall be full of cracks happens occasionally.

2, whole pond body is as the jar shape, and for improving its closed performance, avoiding the consideration of leaking, the discharge port opening that is positioned at the structures top is very little.This little hatch frame makes that air flowing is not smooth in it uncaps Shi Yinchi, the intoxicating phenomenon when usually scarfing cinder taking place.Moreover, little opening makes very inconvenience of scarfing cinder, takes time and effort.

3, the work amount of underground structure is costed big greatly, relatively.

Above problem has seriously restricted the widespread use of biogas.

Summary of the invention:

Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology weak point, provides that a kind of sealing property is reliable, the safe ready of slagging tap, hood bag formula methane-generating pit that laid down cost is low.

The technical scheme that the utility model technical solution problem is adopted is:

Constructional feature of the present utility model is that the gland in its column top of opening wide constitutes described methane-generating pit by open column pond body and gland, glue is set in the air chamber at an upper portion thereof moulds inner bag, described glue is moulded the gas skirt that inner bag is a back-off, the base of gas skirt is lower than liquid level in the pond, and is connected on the body sidewall of pond with removable structure.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model adopts inner-tube structure in air chamber, has solved the leakage problem that the concrete marsh-gas pond may exist with the plastic inner container good air-tightness.

2, the open column of the utility model pond body, and the gas skirt of removable connection makes the tapping process extremely safe convenient.

3, the utility model is because of being provided with inner bag, make its can with upper part of air chamber with the form brick work of concrete pad more than ground, reduced requirement on the one hand greatly for the concrete-pool-wall air-tightness, also reduce quantities on the other hand, reduced the difficulty of construction, thereby reduced the methane-generating pit cost greatly.

Accompanying drawing is the utility model structural representation.

Number in the figure: 1 column pond body, 2 glands, 3 top air chambers, 4 plastic inner containers, 5 raw materials, 6 feeding pipes, 7 pads.

Embodiment:

Referring to accompanying drawing, the gland 2 in its column top of opening wide constitutes methane-generating pit by open column pond body 1 and gland, in the air chamber 3 plastic inner container 4 is set at an upper portion thereof.Shown in the figure, plastic inner container 4 is the gas skirt of a back-off, and the base of gas skirt is lower than liquid level in the pond, and is connected on the body sidewall of pond with removable structure.

For the ease of implementing, reduce cost, pond body sidewall that can air chamber 3 first halves is set to be in the pad 7 more than the ground.

The utility model adopts draining getter method equally, and raw material 5 is deposited in the bottom of column pond body 1, constitutes fixed space by column pond body 1 and gland 2, behind plastic inner container 4 aerificatioies, is placed in the cover tire as air tube, has limited the expansion of plastic inner container 4.Plastic inner container 4 good air-tightness are effectively solved the leakage problem of pond body.When slagging tap, open gland, take off plastic inner container, at this moment, the pond body is open, gas communication, the easy-to-operate of slagging tap.

Claims

1, hood bag formula methane-generating pit, it is characterized in that the gland (2) in its column top of opening wide constitutes described methane-generating pit by open column pond body (1) and gland, glue is set in the air chamber (3) at an upper portion thereof moulds inner bag (4), it is the gas skirt of a back-off that described glue is moulded inner bag (4), the base of gas skirt is lower than liquid level in the pond, and is connected on the body sidewall of pond with removable structure.

2, hood bag formula methane-generating pit according to claim 1, the pond body sidewall that it is characterized in that the air chamber first half are to be in the above pad (7) in ground.
