Abstract

The utility model relates to a hydraulic pressure type moveable-cover-plate-free marsh gas tank with strong inverse flow, comprising a tank body, a tank neck, a fermentation room arranged on the middle lower part in the tank body, a marsh gas storage chamber arranged on the upper part in the tank body, a hydraulic pressure tank arranged on the upper part of the tank body, and a feed pipe and a small discharge pipe which are arranged on both sides of the tank body, wherein the center of the interior of the tank body is provided with a central pipe, the upper part of the central pipe is connected with the tank neck, and the lower part of the central pipe is enabled to extend to a position beneath a material waterline of the fermentation room. A circular overflow pipe is arranged between the hydraulic pressure tank and the feed pipe so as to enable the hydraulic pressure tank to be communicated with the feed pipe. The utility model can not cause the phenomenon of marsh gas leakage, and materials can be directly fed or discharged in great numbers. When the marsh gas in the marsh gas storage chamber pressurizes water into the hydraulic pressure tank and the air pressure is excessively high, the water can be led into the feed pipe by the circular overflow pipe and back flow into the fermentation room, so as to enable the raw materials in the fermentation room to flow to further play a stirring role and be beneficial to fermentation and marsh gas generation.

Description

The strong inverse flow hydraulic type does not have removable cover biogas jar

Technical field

The utility model relates to a kind of biogas jar, and being specifically related to a kind of strong inverse flow hydraulic type does not have removable cover biogas jar.

Background technology

Biogas is in the history in existing several years of application in vast rural area, and the biogas fermentation raw material is based on human and animal excreta.Materials such as human and animal excreta belong to rich nitrogen raw material, are characterized in that fermentation period is short, aerogenesis speed is fast.Methane-generating pit in the past generally adopts brick concrete structure to build by laying bricks or stones and forms, owing to the problems that exist at aerogenesis quantity, use season and a lot of technical elements, so slowly fail to promote the use of.Having now a kind of is the marsh gas jar of biomass pool body with the inorganic compounding glass-reinforced plastic material.This is a kind of hydraulic type biogas jar, and as shown in Figure 1, its principle of work is: hydraulic pressure gas, air pressure water.Without biogas the time, the gas transmission switch is cutting out.Biogas in the gas dome is poly-more many more, and when the pressure of biogas during greater than barometric point, the fermented liquid in the proving room is depressed into ager, and the liquid level of proving room descends, and the ager liquid level raises, and this process is called air pressure water; When opening the gas transmission switch and use gas, the fermentation broth stream in the ager is returned proving room, and biogas is extruded, and is called hydraulic pressure gas; When biogas pressure equaled energetically pressure, pressure reduction disappeared, and biogas stops output substantially.This hydraulic type biogas jar needs the good seal removable cover on request after charging, will note the good seal skylight opening especially, with anti-gas-leak.There is following problem in existing this 8 cubic metres hydraulic type biogas jar through peasant household's use:

1: adding material during rear seal-cover, because of use joint filling material improper, can cause that removable cover is poorly sealed to produce gas leakage;

2: it is dry and cracked and cause gas leakage that the water in the retaining circle is evaporated the back Abdichtungskitt;

3: removable cover gas leakage back, biogas leakage can bring many troubles, lift removable cover again and smear Abdichtungskitt, and also will lift removable cover during big discharging just can discharging.

4, the raw material of sweathouse remains static, and is unfavorable for fermentation gas.

The utility model content

At above-mentioned the problems of the prior art, the utility model provides a kind of removable cover that need not, and can not cause the biogas leakage, and the raw material of sweathouse is flowed, and the strong inverse flow hydraulic type that is beneficial to fermentation gas does not have removable cover biogas jar.

The utility model is that the technical scheme that its purpose of realization is taked is: the strong inverse flow hydraulic type does not have removable cover biogas jar, comprise that the middle and lower part is a sweathouse in tank body, jar neck, the tank body, the tank body internal upper part is an air storage chamber, be provided with ager on tank body top, feed-pipe and little discharge nozzle are established in the tank body both sides, it is characterized in that described jar of intravital centre bit installs pipe core, pipe core top is connected with a jar neck internal orifice, and the pipe core bottom extends to the gauging line below of sweathouse material.

Establish the circulation upflow tube between described ager and the feed-pipe, described ager is communicated with feed-pipe.

The beneficial effects of the utility model: can not produce gas leak phenomenon, can directly reinforced or big discharging by pipe core.When the biogas in the air storage chamber on hydraulic pressure ager, water just entered feed-pipe by the circulation upflow tube when air pressure was excessive, the sweathouse that backflows can make the raw material of sweathouse flow like this, plays stirring action, helps fermentation gas.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is existing hydraulic type biogas jar synoptic diagram;

Fig. 2 is the utility model synoptic diagram.

Embodiment

Referring to Fig. 2, the utility model is that a kind of strong inverse flow hydraulic type does not have removable cover biogas jar, comprise that the middle and lower part is a sweathouse 1 in tank body 15, jar neck 16, the tank body, the tank body internal upper part is an air storage chamber 2, be provided with ager 4 on tank body top, feed-pipe 8 and little discharge nozzle 10 are established in the tank body both sides, ager pipe connecting 9 and airway 12.On the little discharging mouth of pipe 10, ager cover plate 11 is arranged.Described jar of intravital centre bit installs pipe core 13, pipe core 13 tops closely are connected with jar neck 16 internal orifices, pipe core is cast into an integral body with a jar neck, be stamped hole cover plate 7 on the jar mouth, pipe core 13 bottoms extend to gauging line 3 belows of sweathouse 1 material, can arrive the central position (material is meant the human and animal excreta after the fermentation and the mixture of water, will be added to 2/3rds places of tank body usually) of tank body.Establish circulation upflow tube 14 between described ager 4 and the feed-pipe 8, described ager 4 is communicated with feed-pipe 8.The utility model structurally improves prior art, and main improvement is to replace removable cover 5 and retaining circle 6 among Fig. 1 with pipe core 13.In addition, also increased circulation upflow tube 14.

Material of the present utility model can adopt inorganic compounding glass reinforced plastic, and it is in light weight, and the spherical tank of manufacturing 8 cubic metres only weighs about 200 kilograms, is convenient to transportation and installation.Its intensity height also has certain elasticity, is not easy by the frozen soil squeeze crack.Ageing resistance and corrosion resistance nature are also fine, can resist the etch of various organic acids, multiple etchant gas and organic solvent in the methane-generating pit, generally need not maintenance, are work-ing life more than 20 years.In addition, its resistance to air loss and thermal insulation are good, the factor of created gase height.Research shows with application result, the biogas jar that adopts the inorganic compounding glass-reinforced plastic material to make, and good seal performance, the gas leakage of not seeping water, its thermal conductivity is 1.42kj/ (m.h.), factor of created gase and air storage amount all can improve about 30%.Optimum shape of the present utility model is spherical, also can adopt shapes such as square or rectangular parallelepiped.
