Description
Technical field
The utility model relates to biogas fermentation field, refers to that biogas fermentation device is stirred in a kind of broken shell especially.
Background technology
Biogas be organic substance under anaerobic, through the fermentative action of microorganism and a kind of inflammable gas generated.Because this gas is swampy at first, so be called biogas.The various organism such as human and animal excreta, stalk, sewage, in airtight methane-generating pit, at anaerobism (not having oxygen) condition bottom fermentation, namely by miscellaneous methane fermentating microorganism decomposition and inversion, thus produce biogas.Biogas is a kind of mixed gas, can burn.
Organism kinds as biogas fermentation material is various, as fowl and animal excrement, crop material, food processing waste and waste water, and alcohol waste material etc., its main chemical compositions is polysaccharide, protein and lipid.
But mostly there is the problem of the insufficient uneven and consumes energy of fermentation in now widely used tank for sewage gas.Such as, upflow solids reactor (Upflow Solid Reactor, be called for short USR) be applicable to process higher suspension solid material, total solids level (TS) is 5% livestock and poultry feces, in the dirty recycling of current livestock and poultry cultivation industry excrement, have more application.But the feed liquid higher to cellulose, as taken cow dung as fermentation raw material, easily at fermented liquid surface crust, the biogas of generation is difficult to discharge, and affects biogas output.In addition, anaerobically fermenting needs certain temperature, needs extra calorific loss to fermentor tank heating.Therefore, be necessary on the one hand to increase broken scum silica frost facility, the scum layer on destroy fermentation-causing liquid surface at fermentor tank liquid level, adopt cheap heating unit on the other hand, reduce the loss of the energy.
Summary of the invention
In view of this, the purpose of this utility model is to propose a kind of broken shell and stirs biogas fermentation device, solve that the technical problem of the fermented liquid surface crust that prior art exists and heating unit waste energy technical problem.
Biogas fermentation device is stirred in a kind of broken shell provided based on above-mentioned purpose the utility model, comprises tank body, the feeding unit be arranged on tank body, drawing mechanism and air-out apparatus, wherein:
Be provided with horizontal broken shell whipping appts in described tank body, described horizontal broken shell whipping appts comprises the rotation axis be horizontally installed in tank body and the multiple stirring rakes be arranged on described rotation axis; Circumference along described rotation axis is provided with at least two described stirring rakes, and the axis at least two along described rotation axis is circumferentially provided with described stirring rake; Described stirring rake exceeds fermentation liquid level when going to extreme higher position.The magnitude setting of stirring rake and setting position can adjust according to the concrete size of fermentor tank and actual needs.
Described stirring rake vertically arranges or to be obliquely arranged on described rotation axis.
Being arranged on same multiple described stirring rake circumferentially can be different from the oblique angle that arranges of described rotation axis.Angle difference can increase the area that stirring rake contacts with fermented liquid, reaches the more uniform effect of stirring.
The section shape of the focusing surface of described stirring rake and fermented liquid effect is fan-shaped, and described fan-shaped angle is not more than 30 degree.Resistance can be produced and stir fermented liquid, be unlikely to again resistance excessive, consume too much energy.
The surface shape of the focusing surface of described stirring rake and fermented liquid effect is triangular hill, can reduce the power consumption of stirring.
One of described rotation axis circumferentially arranges three described stirring rakes; The axis of described rotation axis arranges the stirring rake of three circumference altogether.
Heating plant is provided with in described tank body.
The external solar energy collector of described heating plant.
Described solar energy collector is connected by heat storage water tank with described heating plant.
As can be seen from above, biogas fermentation device is stirred in the utility model broken shell can prevent fermented liquid surface crust by the rotation of a rotation axis, realizes the uniform fermentation of full tank material.Adopt solar energy collector supply heat simultaneously, decrease energy consumption, protect environment.
Accompanying drawing explanation
Fig. 1 is that biogas fermentation device one-piece construction schematic diagram is stirred in the utility model broken shell.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
Biogas fermentation device is stirred in a kind of broken shell as shown in Figure 1, comprise tank body 1, the feeding unit 2 be arranged on tank body, air-out apparatus 3, wherein be provided with horizontal broken shell whipping appts 4 in tank body 1, this horizontal broken shell whipping appts 4 comprises the rotation axis 41 be horizontally installed in tank body 1 and the multiple stirring rakes 42 be arranged on rotation axis 41.A circumference along described rotation axis 41 is provided with three stirring rakes 42, and the axis along rotation axis 41 has at least three to be circumferentially provided with stirring rake 42.Stirring rake 42 exceeds fermentation liquid level when going to extreme higher position.In other embodiments, the magnitude setting of stirring rake 42 and setting position can adjust according to the concrete size of fermentor tank and actual needs.
As shown in Figure 1, stirring rake 42 is vertically set on rotation axis 41, the same position of stirring rake 42 impact fermentation liquid level repeatedly when rotation axis 41 rotates.
