The utility model has the advantages of:
Domestic refuse of the present utility model and farm crop straw organism dry-type anaerobic fermentation treatment device, described fermentation vat builds up arch top, is convenient to collect biogas; Described door opening/closing apparatus is hydro valve door gear, described door opening/closing apparatus drives hermatic door to do relative rotation around door twisted axis, realize the Push And Release in hermatic door and bell hole, in the time closing the door state, sealed strip is adjacent at the periphery in bell hole and realizes sealing function, and in the time opening the door, exhaust-valve is opened, and fermentation vat communicates with atmosphere, reduce the air pressure in fermentation vat, discharge the gas of methane residual in fermentation vat; Described fermentation vat is dry type fermentation vat.
Dry type fermentation vat builds up moudle type, and several recycle, and have realized the continuity of rubbish and agricultural crop straw processing and aerogenesis.Because the acidifying gas before each aerogenesis cycle is discharged from, this is also that the dry type fermentation biogas purity of producing produces than wet type the basic place that biogas hydrogen sulfide content is low.
Biological dry-type anaerobic fermentation not water does not just have natural pond liquid discharge, non-secondary pollution.
Rubbish per ton and producing biogas from crop straws 120-150 ㎡, recycling rate is high, profitable.
Because dry type fermentation vat intermittent type uses and discharges in advance acidifying gas, biogas purity is high, CH4 >=65%, H2S≤12ppm.
Dry type fermentation 25-30 days is that one-period domestic refuse and farm crop straw organism fermentation time are long, before degrading thoroughly, fermenting, has sub-elected magneticmetal material and battery class heavy metal, and natural pond slag fertilizer efficiency is high, heavy metal content is low.
Fermentation vat builds up modularization, and several recycle uninterrupted rubbish and stalk processing and supply continuously biogas, are suitable for mass-producing processing.
Biological dry-type anaerobic fermentation is with natural pond slag and ooze drop liquid inoculation biological bacteria without any need for additive and water, and the few running cost of occupation of land is low.
Be applicable to organic solid rubbish individual curing and with agricultural crop straw combination treatment, wide accommodation.
Principle of design of the present utility model is as follows:
First use when not containing the natural pond slag of bio anaerobic bacterium and oozing the inoculation of drop liquid, should carry out cultivation domestication inoculation bio anaerobic bacterium; What produce oozes drop liquid by the recovery pipe network of dry type fermentation vat bottom, by backflow sewage electric pump, the described drop liquid that oozes is recovered to and oozes drop liquid basin and bio anaerobic flora and inoculate and recycle; Sorting consumer waste organic materials out and the agricultural crop straw each 50% of chopping, add again 25-30% Shang batch to go out the natural pond slag of pond containing bio anaerobic bacterium, mix the effect of playing inoculation bio anaerobic bacterium with forklift, and pack the 45-55% of dry type fermentation vat internal volume into, close hermatic door; Open and ooze drop liquid and store tank connected sprinkling system, described sprinkling system comprises water outlet pipe connecting, spray sewage electric pump, oozes drop liquid pipe, shower; By described sprinkling system spray into contain bio anaerobic bacterium ooze drop liquid, play the effect of damping inoculation bio anaerobic bacterium, make raw material keep the moisture content of 65-75%, due to rubbish and agricultural crop straw enter to have mixed uniformly before fermentation vat natural pond slag inoculation again spray contain bio anaerobic bacterium ooze drop liquid, saved the agitating procedure of fermenting process, described recovery pipe network comprises isolation double-edged fine-toothed comb, oozes drop liquid recovery tube, backflow pipe connecting, backflow sewage electric pump.Fermenting raw materials is souring stage in first 48-72 hour, and acidifying pneumatic transmission is entered ultraviolet deodorizing device emission abatement by the by-pass tube valve of opening on collecting methane pipe network; After 72 hours, produce biogas, first close hydrogen sulfide drain tap, then open towards the valve of biogas storage cabinet, biogas enters gas-holder.It is a treatment cycle that raw material ferments 25-30 days in fermentation vat, organic waste per ton and producing biogas from crop straws 120-150m3; Dry type fermentation vat builds up moudle type, and several recycle, and have realized the continuity of rubbish and agricultural crop straw processing and aerogenesis.Because the acidifying gas before each aerogenesis cycle is discharged from, this is also that the dry type fermentation biogas purity of producing produces than wet method the basic place that biogas hydrogen sulfide content is low.The remaining methane gas of Zha Chu pond, natural pond front opening exhaust-valve ventilation emptying, prevents that operator are poisoning, transports natural pond slag with forklift.Because dry type fermentation fertilizer efficiency is all retained in the slag of natural pond, sub-elect magneticmetal thing and battery class material entering Chi Qianyi, therefore natural pond slag is the high bio-fertilizer of fertilizer efficiency.Domestic organic garbage and agricultural crop straw spray by natural pond slag combined inoculation bio anaerobic bacterium and in fermentation vat and ooze drop liquid damping inoculation anerobe, through the 35-38 DEG C of mesophilic digestion of 25-30 days, if with 53-55 DEG C of thermophilic fermentation, fermenting speed is fast, efficiency is high, but the season low with temperature in the winter time, do not calculate for warm cost height, adopt the hot-water coil pipe heating being arranged in fermentation vat winter, only consume the 3-5% of self production capacity with marsh gas stove heating, the combustiblematerials heating that employing sub-elects does not just consume the production capacity of self, rubbish per ton and mixed stalk raw material produce biogas 120-150m3, CH4 >=65%, H2S≤12ppm.Natural pond slag is efficient biologic-organic fertilizer, has realized harmless treatment, recycling.
Finally it should be noted that: above embodiment is only for illustrating the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
