Description

A kind of high-order discharging dual reflux biogas fermentation device
Technical field
The utility model relates to the hydraulic type biogas fermentation device that uses in the biogas fermentation field, is specifically related to a kind of high-order discharging dual reflux biogas fermentation device.
Background technology
China's biogas technology developing history existing seventy or eighty years, the hydraulic type biomass pool that present stage promotes, its pond type, structure and build pool technology and form through for many years transition and the continuous summary of repeatedly practising many times.Hydraulic type biomass pool is the pond type that China promotes the earliest, quantity is maximum, although the kind of hydraulic type biomass pool has a lot, Full Featured methane-generating pit all should comprise with the lower section: between skylight opening, airway, feed-pipe, opening for feed, sweathouse and air storage, discharge nozzle, water pressure house.It has following advantage: (1) pond body structure stress performance is good, and makes full use of the supporting capacity of soil, so labor and material saving, cost is lower.(2) be suitable for loading multiple fermentation raw material, particularly a large amount of crop materials, very favourable to the rural area collected manure.(3) for ease of frequent charging, lavatory, pigsty can be built in above the methane-generating pit, and ight soil can both be swept into pond at any time.(4) all contact with soil around the methane-generating pit, insulation has certain effect to the pond body.But the hydraulic type biomass pool type that promote in the rural area adopts charging every day and discharging could form the circulation of continuously fermenting of a mobile.On the one hand, owing to there is not whipping appts, scum silica frost crusts easily in the pond in, and the easy layering of raw material can not automated cycle, so the utilization ratio of fermentation raw material is not high, it is on the low side that the pond holds factor of created gase, and generally factor of created gase only is 0.15 meter every day 3About; On the other hand, because the wayward property of quality, composition of temperature, charging quantity and charge raw material, often exist fermentation not exclusively, not thorough, when needs heavy dressing discharging, ubiquity is given birth to, grog mixes, can not effectively kill various pathogenic agent again easily when producing " green product ", be subjected to secondary pollution, make the comprehensive utilization aspect of natural pond liquid, natural pond slag be subjected to very big influence.
Summary of the invention
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides the not high-order discharging dual reflux of miscellaneous biogas fermentation device of a kind of fermentation finished thoroughly1, life, grog.
For achieving the above object, the technical scheme that the utility model is taked is that this high position discharging dual reflux biogas fermentation device comprises fermentation vat, gas dome, water pressure house, feed space; Between water pressure house and feed space, establish check valve; Offer opening for feed and discharge port at fermentation vat pool wall middle part, described opening for feed is communicated with feed space and water pressure house respectively by pipeline with discharge port; Handicapping stream wall between discharge port in fermentation vat and the opening for feed, choked flow wall head end closely contacts with the pool wall of discharge port, opening for feed one side, the choked flow wall is to the inner extension of pond body, tail end does not contact with bay wall, the feed liquid face is high slightly in the bottom level of choked flow wall bottom and fermentation vat, choked flow wall body of wall aspect ratio fermentation vat.
Described choked flow wall adopts curved surface choked flow wall, its extension path is half arc, lay prominent head on choked flow wall surface, adopt half curved wall can make full use of the effect of spiral camber at the bottom of the pond, make into pond raw material technical ability and increase flow process, unlikely obstruction, reduce the fermentation blind area, play rich poly-bacterial classification again, increase the effect of stirring, choked flow wall surface is provided with prominent head in addition, and coarse injustice is convenient to organism of fermentation and is adhered to also rich poly-, form microbial film, coarse metope also can carry out broken shell and stirring to incrustive pond material simultaneously.
The top of described fermentation vat is coated with thin film layer, cuts off ground temperature and the heat conducting approach in the face of land with plastic layer, guarantees the winter low temperature normal gas producing.
The top of described gas dome offers the removable cover mouth, on the lid mouth removable cover is set, and passes in and out and get rid of the passage of remaining obnoxious flavour when ventilation and lighting was with maintenance when the removable cover mouth was construction of marsh gas tank.
Described high-order discharging dual reflux biogas fermentation device also comprises refluxing takes out the slag device, and backflow is taken out the slag device and is made of dreg-drawing pipe and piston, and the end of taking out the slag device that refluxes is connected with fermentation vat; By piston moving up and down in pipe, extract natural pond liquid or natural pond slag from sweathouse, reach the purpose of discharging stirring, backwashing.
Because the utility model is taked technique scheme, installs check valve between water pressure house and feed space, wall is flowed in handicapping in fermentation vat, has formed the path of a feed liquid pump around circuit in device, that is: feed space → fermentation vat → water pressure house → feed space; Wall is flowed in handicapping in fermentation vat simultaneously, after the pond raw material must be made a circulation along the choked flow wall, could get rid of from tapping channel, increased flow process and the residence time of feed liquid in the pond, eliminated " the poor district of microorganism ", " fermentation blind area " and " feed liquid short circuit " phenomenon, improved the stirring of pond material greatly, thereby improved utilization ratio, increased the gas production rate of unit pond material the pond material, secondly, discharge port is arranged on the middle part of fermentation vat, effectively stirs the high-order pond material in the fermentation vat, further reduces " fermentation blind area " from three-dimensional face, be equivalent to increase the fermentation vat volume, therefore can reduce gas dome, thereby reduce the time of impurities removal gas when promptly starting, start fast; Once more, because the pond material has passed through sufficient stirring in the fermentation vat, unleavened raw material are remaining less, pathogenic bacteria, parasite have obtained effectively killing, when natural pond slag as fertilizer sources is used, be subjected to secondary pollution when having avoided " green product " fertilising, natural pond liquid, the utilization of natural pond slag on agricultural are improved.Compared with prior art, the utlity model has the utilization ratio that improves the pond material, increase gas production rate, start fast, can effectively kill pathogenic bacteria, parasitic advantage.
