Description

A kind of fermentation cabin top biogas pipe-in-pipe

Technical field

The utility model belongs to biogas fermentation equipment technical field, and in particular to a kind of fermentation cabin top biogas pipe-in-pipe.

Background technique

Sludge gas dry fermentation refers to using organic waste as raw material (dry substance concentration is 20% or more), produces acid using hydrolysis Bacterium, hydrogen-producing acetogenic bacteria and methanogen are broken down into the zymotechnique of the gases such as CH4, CO2, H2S.Due to solid concentration It is too high-leveled and difficult with using continuous dosing or partly the feeding mode that feeds intake, the overwhelming majority are all made of fed batch.The technical process are as follows: point Organic waste after choosing or the agricultural crop straw and livestock and poultry feces being mixed in a certain ratio, pour dry fermentation by forklift superfast loading In storehouse, raw material closes hatch door after filling fermentation cabin, and the percolate that leachate collection system is collected is by pumping into percolate fermentor In ferment, the percolate after fermentation by percolate spray system be fermentation cabin in raw material spray inoculation, the liquid of exudation Enter percolate fermentor again by leachate collection system, constantly recycled with this, is constantly the raw material inoculation in fermentation cabin, Improve the factor of created gase of dry fermentation raw material.

Dry fermentation storehouse is very high to air-tightness requirement, is unable to gas leakage, cannot have air to enter in storehouse, usually straight rigid enclosure Pipe is directly embedded into the corresponding position of concrete, and the permeability of biogas is very strong, in addition the telescopicing performance of concrete and steel pipe is not Equally, the biogas in storehouse is very easy to overflow from the crack of rigid casing and the contact surface of concrete, causes biogas to leak, in storehouse Raw material causes raw material to produce biogas efficiency and substantially reduces because there is the entrance of oxygen not can be carried out anaerobic methane production.

Utility model content

The purpose of this utility model is that:

Crack for the contact surface of casing and concrete in solution dry fermentation storehouse is easy leakage biogas and penetrates into oxygen Problem, and a kind of fermentation cabin top biogas pipe-in-pipe is provided.

The technical solution adopted in the utility model is as follows:

A kind of fermentation cabin top biogas pipe-in-pipe, which is characterized in that including rigid casing, the rigid casing lower opening Place is equipped with horn mouth, and rigid casing outer surface is connected with anti-hydrofoil ring, and the anti-hydrofoil ring is in the horizontal plane circumferentially around rigid The outer surface of property casing.

Rigid casing is used to be set in outside biogas pipe and is embedded in rigid casing in the fermentation Hold Ceiling of concrete material, and It first pre-buried rigid casing, the lower ending opening of rigid casing to be flushed with fermentation Hold Ceiling bottom before concreting, rigid enclosure The upper section of pipe stretches out fermentation Hold Ceiling.

Further, it is less than rigid casing installation to the height at lowest calibre at the horn mouth maximum caliber The existing tubaeform nozzle in installation section of depth, i.e. rigid casing in fermentation Hold Ceiling also has the tube body of straight-tube portion.

Further, location wing ring is also connected on the rigid casing outer surface, the location wing ring is located at anti-hydrofoil The top of ring, the wing ring diameter of location wing ring are greater than the wing ring diameter of the anti-hydrofoil ring.The lower surface of location wing ring and fermentation The upper surface of the top plate in storehouse flushes and is in contact, and the bigger location wing ring of diameter can integrally play a supportive role to casing.

Further, on the outer surface of the rigid casing between the location wing ring and anti-hydrofoil ring and anti-hydrofoil ring and Elastic packing sleeve is arranged on the outer surface of rigid casing between bell-mouthed lowest calibre.

Further, the elastic packing sleeve is made of rubber.

The working principle of the utility model is as follows:

The rigid casing of straight tube-like in the prior art is improved to tubaeform, dry fermentation by the biogas pipe-in-pipe of the utility model The biogas generated in storehouse touches the gap between the horn mouth of casing and fermentation Hold Ceiling during riseing upwards, due to its seam The contact surface of gap and vertical direction are comparably inclined-plane, due to by force resolution, so that the gas of vertical ascent infiltrates through inclined-plane Gap difficulty is bigger, while increasing anti-hydrofoil ring, and the path for while gas gas being exosmosed from gap is stopped to lengthen, into One step reduces the leakage of biogas, is also prevented from oxygen and penetrates into dry fermentation storehouse.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:

1. the horn mouth of the utility model setting makes the gas of vertical ascent infiltrate through rigid casing and fermentation Hold Ceiling Between inclined slot difficulty increase, while increasing anti-hydrofoil ring and extending the path that passes through of extravasation gas, with the prior art without the wing The casing of ring is compared, and can effectively reduce that biogas leaks from inside to outside and oxygen permeates from outside to inside, to significantly improve biogas Factor of created gase.

2. the existing tubaeform nozzle in installation section of the biogas pipe-in-pipe of the utility model and fermentation Hold Ceiling also has straight tube Partial tube body, compared with the prior art in straight tube-like casing, the casing installation section of the utility model is not susceptible to entirety Flexible, sliding, can avoid generating biggish crack due to the different casings of telescopicing performance and the contact surface of concrete, to subtract The leakage of few gas, guarantees the factor of created gase of biogas.

3. the biogas pipe-in-pipe of the utility model is also connected with location wing ring, location wing ring has following two points effect: pacifying Joints cement again can be facilitated after casing is accurately positioned when dress, avoid sleeve position from deviating, guarantee that it is correctly installed, has Effect prevents from revealing；The position for further fixing casing between the Hold Ceiling that ferments is combined with the anti-hydrofoil ring in insertion concrete, To prevent that gap causes to reveal.

4. the elastic packing sleeve of the utility model setting, can be pressed on casing by concrete, fill straight pipe Gap between sleeve outer wall and fermentation Hold Ceiling reinforces sealing effect, and the small size stroke of absorbable casing, avoids casing It is ruptured because of dilatation.

5. the elastic packing sleeve of the utility model uses rubber material, bullet can be enhanced while guaranteeing sealing effect Property, effective protection is carried out to casing, extends the service life of casing.
