Abstract
The utility model discloses a straw methane tank. An aerobic fermentation tank is arranged above a feeding pipe mouth; the upper part of a discharging pipe is connected with a water pressure tank; a one-way valve is arranged at the upper end of the discharging pipe; a reflow pipe is connected between the water pressure tank and the inner top of the fermentation tank at the top; and a settling tank is arranged at the bottom of the water pressure tank. According to the straw methane tank disclosed by the utility model, the difficulty of straw fermentation and the defects of a traditional methane tank are overcome, so that biogas slurry can automatically circulate on an intermediate layer and a bottom layer of the fermentation tank and raw materials and strains in the tank are uniformly distributed. The pressure in an anaerobic fermentation tank is used as a power source, so that the liquid level in the aerobic fermentation tank at the upper end of a feeding pipe is up and down fluctuated and the raw materials in the aerobic fermentation tank are positioned in a dry environment and a humid environment for a long time with the liquid level up and down fluctuated, and further the increase of the fermentation temperature is facilitated and the biologos is excited. Feed liquid is directly heated by using solar energy, so that the straw methane tank has the advantages of high automatic degree, economy, convenience, strong adaptability and greatly-increased gas yield.
Description
Technical field
But the utility model relates to a kind of device of process gas fuel, a kind of stalk marsh gas pond of more specifically saying so.
Background technology
At present, the rural area household methane tank generally is made up of feed-pipe, anaerobically fermenting pond, extraction line and gas tube, and feed-pipe, extraction line lay respectively at the fermentation vat both sides and be connected with fermentation vat, and gas tube is positioned on the fermentation vat top cover.This traditional methane tank largely is confined to make fermentation raw material with human and animal excreta, uses the fermenting straw raw material time long, weak effect; Efficient is low; And following shortcoming arranged: the one, because raw material in small, broken bits is floated by the bubble effect, the fermentation vat liquid level is prone to crust, influences normal gas producing; The 2nd, be prone to heavy collection slag charge at the bottom of the fermentation vat pond, its long-term effective pond of influence of heaping holds; The 3rd, natural pond liquid does not flow, and strains'distribution is uneven, and gas production rate is low; The 4th, raw material is skewness in the pond, and ferment effect is poor.Along with the rural area situation development, culture the change of structure, culture peasant household and disperse day by day; The human and animal excreta fermentation raw material more and more reduces; Household biogas development receives restriction largely, and rural area straw, organic waste, resource are inexhaustible, and it is imperative that the straw methane-generating pit is improved in exploitation.
The utility model content
The problem that the utility model will solve is to provide a kind of stalk marsh gas pond, overcomes the difficult point of stalk fermentation and the shortcoming of traditional methane tank, makes natural pond fluid power enough middle level and bottom automated cycle at fermentation vat, and raw material and strains'distribution are even in the pond, and aerogenesis is effective.
The utility model adopts following technical scheme, and a kind of stalk marsh gas pond is provided with an aerobic fermentation pond above the charging mouth of pipe.
Said aerobic fermentation pool volume is less than the anaerobically fermenting pond, and the suitable for reading of pond is the inclined-plane, is provided with sealing cover.The extraction line top links to each other with a hydraulic pressure pond, and is provided with a vacuum breaker in the extraction line upper end, and the hydraulic pressure pond is connected a return line with the interior top of fermentation vat highest point.
Establish a settling tank in bottom, hydraulic pressure pond.
Through technique scheme, realized aerobic and the fermentation of anaerobism branch pond, overcome the situation that hydrolysis, product are sour, product methane is treated different things alike of traditional methane tank.Adopted circulation route in the anaerobically fermenting pond, changed traditional circulation route from the opening for feed to the discharge port from lowest part at the bottom of the pond to top, pond highest point.Overcome the limitation of raw material; Improve the return rate of raw material, created optimum growh, metabolism environment for the different monoid mikrobes of each fermentation stage, solved automatic stirring, automatic sludge discharge, automatic shell-breaking; The biogas that favourable bag of while is dissolved in the raw material discharges smoothly; The sinking of waste residue, organism resolving time and biological denitrification process are secure, and the discharge hygienic standard is high.Having borrowed anaerobically fermenting pond internal pressure is propulsion source,
Make in the aerobic fermentation pond, feed-pipe upper end liquid level one on the other, raw material is in one dried one environment that wets for a long time in the pond in, and favourable raising leavening temperature excites biologos.Use sun power and directly heat to feed liquid, its level of automation is high, and economical convenient, flexibility is strong, and factor of created gase improves greatly.
Description of drawings
Below in conjunction with embodiment the utility model is done further detailed explanation.Fig. 1 is a kind of example structure principle schematic of the utility model.
Embodiment
As shown in the figure, a kind of embodiment of the utility model comprises aerobic fermentation pond 1, feed-pipe 2, anaerobically fermenting pond 3, removable cover 4, gas tube 5, extraction line 6, vacuum breaker 7, hydraulic pressure pond 8, settling tank 9, return line 10.Aerobic fermentation pond 1 is located at feed-pipe 2 places suitable for reading, and aerobic fermentation pond 1 volume can load the about seven days desired raw materials in anaerobically fermenting pond just less than anaerobically fermenting pond 3, and aerobic fermentation pond 1 is 50-80cm deeply, and low north, pond mouth south is high; 45 degree inclined-planes cover sealing with topotype.Extraction line 6 tops link to each other with a hydraulic pressure pond 8, and are provided with a vacuum breaker 7 in the extraction line upper end, and hydraulic pressure pond 8 is connected a return line 10 with anaerobically fermenting pond 3 interior top highest points, establishes a settling tank 9 in 8 bottoms, hydraulic pressure pond.
Stalk is accomplished hydrolysis in the aerobic fermentation pond, behind the acid process, get into the anaerobically fermenting pond through feed-pipe; Be suspended in this pond; Along with the intensification of attenuation degree, successively sink, finally become at the bottom of active sludge and the carbon granules sinking pond; Under the effect of pond internal pressure, these sediments get into the hydraulic pressure pond in company with feed liquid by extraction line.Centre has a settling tank at the bottom of the hydraulic pressure pond, can realize that here slag liquid separates automatically, and a vacuum breaker is established in extraction line upper end, prevents during with gas that the former road of feed liquid from returning, and forces feed liquid to pass through return line, and highest point scatters in the pond.These pond main points: use anaerobically fermenting pond internal pressure, make in the aerobic fermentation pond, feed-pipe upper end liquid level one on the other, raw material is in one dried one environment that wets for a long time in the pond in, and favourable raising leavening temperature excites biologos.
