Description
Technical field
The present invention relates to methane-generating pit field more particularly to a kind of efficient hydraulic type biomass pool devices.
Background technology
The common hydraulic type biomass pool in rural area is one by main fermentation pond () and (pipe) is connected between charging and discharging appearance
Device, during non-aerogenesis, feed pipe, sweathouse, water pressure chamber feed liquid in same level.During aerogenesis, decomposed through microbial fermentation
And the biogas generated is risen between air storage, air tight due to being sealed between air storage, biogas constantly gathers, and just generates pressure.Work as biogas
When pressure is more than atmospheric pressure, just the feed liquid in methane-generating pit is extruded, water level rises in feed pipe and water pressure chamber, sweathouse hydraulic pressure
Decline, produce water-head.Since water-head will make the biogas in air storage keep certain pressure.During with gas, biogas is from leading
Tracheae exports, and the flow of water pressure chamber returns sweathouse, i.e. water pressure chamber water level decreasing, and sweathouse water level rises.By water pressure chamber water level
Automatic lifting, the biogas pressure between air storage is enable to automatically adjust, keep biogas stablize conveying.
The production and use of marsh gas is mainly using stalk as raw material sources, since stalk is cellulosic material composition, in air
It is easily dry.Since traditional hydraulic type biomass pool does not have agitating device, it is smaller that crop material enters methane-generating pit rear portion proportion
Stalk float to feed liquid surface layer formed it is dry under wet crust, could only be contacted below with water.When methane-generating pit runs a period of time
Afterwards, scum layer thickens, is dried, and eventually forms dry and is difficult to broken crust.Crust can lead to the biogas generated in methane-generating pit
Gather and be obstructed, reduce the dischargeable capacity of methane-generating pit and the volume of gas dome, the utilization rate for also leading to fermentation raw material is not high, crust
Constrain the hydraulic type biomass pool gas promotion and application using stalk as raw material.In order to solve this problem, prior art discloses
The methods such as heating, stirring, reflux, setting barrier prevent or reduce the generation crusted.But peasant can be increased by increasing heating unit
Cost, mechanical agitation can increase human cost and mechanical device can hinder the disengaging of peasant household, and reflux can increase return valve
The problem of failure etc. is new, setting barrier is as barrier fails less than liquid level.
Invention content
The present invention is to overcome above-mentioned defect in the prior art, and crust can be abolished automatically without outer power by providing one kind
Hydraulic methane pool device.
To achieve the above objectives, the technical solution that the present invention takes is as follows：
A kind of efficient hydraulic type biomass pool device, it is characterised in that：Anaerobic fermentation room (1) is pyramidal structure.
Preferably, the one kind of anaerobic fermentation room (1) for cone and elliptic conic shape.
Preferably, the interior bevel edge of anaerobic fermentation room (1) vertical section and the angle of horizontal plane are 70-80 degree.
Preferably, hydraulic chamber (2) feed inlet (3) and gas-guide tube (4), hydraulic chamber (2) and feed inlet (3) distribution are further included
It connects respectively in anaerobic fermentation room (1) both sides and with anaerobic fermentation room (1), gas-guide tube (4) is arranged on anaerobic fermentation room (1)
Portion.
The principle of the present invention：
In order to easily generate crust when solving the problems, such as traditional hydraulic type biomass pool using crop material as raw material, the present invention carries
For a kind of hydraulic type biomass pool of taper, anaerobic fermentation room bevel edge is 30-80 degree with ground-angle, and exactly anaerobic fermentation pond is done
The pond body big into a small lower part of upper part, the setting of the inlet port and outlet port of methane-generating pit and conventional hydraulic methane
Pond is similar, is fed in bottom and in bottom discharge.Since the small lower part in part is big on methane-generating pit, when aerogenesis and during with gas, liquid
Face can be down or up therewith, and the size of liquid level can also change.When liquid level declines, liquid level becomes larger, when liquid level rises
When, liquid level can reduce.Crop material, which enters after methane-generating pit, forms scum layer, but during with aerogenesis and with gas, liquid level can rise,
Scum layer will be squeezed, simultaneously because hydrostatic flow action can also play the role of scum layer certain rolling, this
Sample scum layer is pressed into liquid in the following, come into full contact with liquid again, improves the utilization ratio and methane-generating pit of raw material
Fermentation efficiency.Change due to the liquid level size in methane-generating pit with aerogenesis and with gas, thus, the size of liquid level is repeatedly
Variation, scum layer does not stop by corresponding squeezing action, so as to avoid the generation of crust.
Advantages of the present invention and effect：
1. the present invention and conventional cylindrical pattern biogas ratio reduce the probability of crust generation, that improves methane-generating pit utilizes effect
The utilization ratio of rate and stalk, thus be conducive to improve the fermenting speed of methane, the formation scum layer of methane-generating pit of the present invention is than circle
The scum layer of cylindricality methane-generating pit reduces more than 85%, and methane-generating pit total gas production of the present invention increases by more than 9% than cylindrical, the present invention
Methane content in the biogas of methane-generating pit generation is than more than 7% cylindrical growth.
2. the present invention and hemispherical biogas ratio, since its fermenting cellar bevel edge gives scum layer extrusion stress bigger, formation
Scum silica frost layer thickness smaller, reduces the probability of crust generation, thus is conducive to improve the fermenting speed of methane, methane-generating pit of the present invention
Formed scum layer than hemispherical methane-generating pit scum layer reduce more than 83%, methane-generating pit total gas production of the present invention than hemispherical increase
Long by more than 13%, the methane content in the biogas of methane-generating pit generation of the present invention increases by more than 13% than hemispheric.
3. the present invention reduces machine cost and cost of labor compared with stirring-type methane-generating pit, compared with biogas slurry flows back, Du
The generation of the failures such as reflux failure absolutely.
