Abstract

The utility model discloses a liner special for a marsh gas tank for automatically material feeding and residue discharging, which comprises an enclosed pool, a material inlet, a residue outlet, and air outlet provided above the pool, and is characterized by a water pressure duct opening disposed on one side of the pool. The pool is made from PVC or PV material. The liner special for the marsh gastank with such a structure includes an outer casing made from construction material in prior art, which constructs the entire marsh gas tank with the liner special for the marsh gas tank. Because thepool is made from PVC or PV material, and has great stability, phenomena of pool breakage and water and gas leakage caused by geological or orographical change is avoided. Water can be injected intothe pool through the water pressure duct opening to cause the material level in the pool to rise, so that the volume from the material level to the inner top of the pool is reduced, pressure of marshgas is increased, and the marsh gas has sufficient pressure for use by people. The liner is suitable for various kinds of marsh gas tanks.

Description

Cover in the methane-generating pit special use of a kind of automatic feed and deslagging

Technical field

The utility model relates to a kind of container of geseous fuel, especially methane-generating pit.

Background technology

Biogas is a kind of energy as everybody knows, and it is a fermentation raw material with human and animal excreta, sewage, straw, weeds and various waste water etc., ferments in the pond of sealing, and the gas of generation---biogas can be used for burning and produces heat energy.Biogas is a kind of energy of protecting environment and cleaning, is easy to obtain, and cost is low and easy to use.Under the advocating and support of the Chinese government, in decades in the widespread use of the town and country of China, in people's life, send out brightness very effect, brought a lot of material benefits to the people.In the process that biogas produces, methane-generating pit plays an important role.Through examination, the existing methane pool great majority are to build up with brick, cement, sand, stone or synthetic concrete.Its structure is generally: be respectively equipped with an opening for feed on the both sides of a sealing pond body, a slag notch draws an air outlet on the body of pond, be used for burning.Opening for feed and slag notch coexist on the horizontal plane, after material and feed inlet and outlet maintain an equal level, if having material to enter from opening for feed again, then advance how many material, just also go out how many material at discharge port, regulate automatically.The making workload of this methane-generating pit is big, and sealing difficulty is big.Have because of the soil property in place badly in actual use, cement, sand, stone or synthetic concrete ratio are improper.Many methane-generating pits owing to the geology change of topography, can produce the pond body and break after use for some time, the phenomenon of the gas leakage of leaking.Because methane-generating pit generally is provided in a side of under the ground level, maintenance is difficulty.

The utility model content

The purpose of this utility model provides the interior cover of methane-generating pit special use of a kind of automatic feed and deslagging, constitutes methane-generating pit with shell, overcomes the deficiency of existing methane-generating pit, is people's services better.

The technical solution of the utility model is:

Cover in the methane-generating pit special use of a kind of automatic feed and deslagging, it comprises pond body and the opening for feed and the slag notch of sealing, and the escape pipe that is provided with in pond body upper end, it is characterized in that:

Side at the pond body is provided with the hydraulic pressure porthole.

Described pond body is made by PVC or PV material.

Cover is made shell with existing brick, cement, sand, stone or the synthetic concrete material of building used for methane tank in the methane-generating pit special use of above structure, and cover constitutes a complete methane-generating pit in the special use of this methane-generating pit.The pond body of cover is to be made by PVC or PV material in this methane-generating pit special use, and its price is low, good stability, handling ease, good airproof performance and durable.Basically got rid of because of the geology change of topography, caused the pond body to break, the phenomenon of the gas leakage of leaking; Also can inject water in the pond by the hydraulic pressure porthole, the charge level in the pond is risen, reduce charge level and cause the inboard capacity in top, pond, promptly increase the pressure of biogas, making has the biogas of enough pressure for people to use on the cooking stove.

Fig. 2 is the plan structure synoptic diagram of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, step explanation when the utility model is done.

Shown in Figure 1, be sectional structure synoptic diagram of the present utility model.As we know from the figure, on the left and right sides wall of rectangle closed cell body 1, be respectively equipped with opening for feed 2 and slag notch 3, and in the upper end of pond body 1 rear wall, the production well pipe 4 that is provided with.Plan structure synoptic diagram Fig. 2 in conjunction with Fig. 1, on pond body 1 front side wall, be provided with hydraulic pressure porthole 5, by these hydraulic pressure porthole 5 filled waters, improve the height of ferment in the pond body 1 charge level or liquid level, capacity in reducing between fermentation charge level or liquid level and pond body 1 inner crest face, the pressure of increase biogas.Wherein, rectangle closed cell body 1 adopts PVC or PV material to make.Opening for feed 2, slag notch 3 and hydraulic pressure porthole 5 are located on the same plane on the pond body 1.

Principle of work of the present utility model is:

The brick of using in the outside of pond body 1, cement, sand, stone or synthetic concrete material are made corresponding shell, and can corresponding feeding-passage and charging pond are set on opening for feed 2, slag notch 3 and hydraulic pressure porthole 5, go out slag bath and go out to look into passage, and the hydraulic pressure pond.Wherein, feeding-passage and charging pond, go out slag bath and slag releasing channel also is provided with corresponding sealed against leakage gas facility, the siphunculus of hydraulic pressure pond and hydraulic pressure porthole 5 is subjected to the control of switch.The height of the volume in the pond body 1, opening for feed 2 and slag notch 3 and hydraulic pressure porthole 5, and the biogas that produces in pond pressure is just to reserve when design.After fermentation raw material enters pond body 1 inner chamber by feeding-passage and charging pond, produce biogas.Because be that sealing is gastight in the pond, constantly the biogas density that produces increases, increased pressure.The biogas that produces in the general pond is pressed and is equal to and greater than 6KP and gets final product the air feed use when above.Increasing of pond internal pressure biogas can be pushed fermentation raw material downwards.When the air pressure in the pond reaches 8～10KP usually, fermentation raw material can be pushed 30～50CM downwards.The use of biogas can make the air pressure of pond body 1 slowly reduce, and the height of the fermentation raw material in the pond also can rise thereupon.Opening for feed 2, slag notch 3 and hydraulic pressure porthole 5 are located on the same plane on the pond body 1 for a certain reason, raw material by fermentation is a slag, fermentation raw material rises the back slag slowly to slag notch 3 with go out slag bath and slag releasing channel moves and discharges, and promptly old raw material is discharged from material-output tank and tapping channel automatically; New raw material enters in the pond body 1 from feeding-passage and charging pond automatically, and the discharge that enters with old material of this virgin material is slowly, if the hydraulic pressure pond of this moment and the siphunculus switch of hydraulic pressure porthole 5 are being opened, then water is also gone in the pond body 1 by hydraulic pressure porthole 5 automatically, improve the fermentation liquid level, replenish the deficiency of liquid level in the pond body 1, keep-up pressure, guarantee to use.So, the utility model energy automatic feed and deslagging, and the biogas pressure in the maintenance pond body 1.
