Abstract
A cover film fixing net is a device mounted above the black film methane tank gas storage cover film, and is fixed by fixing stakes at the periphery. The stakes are used for tensing a rope net adopting a net structure; the gas storage cover film below the rope net is limited within a certain height range to allow the gas storage cover film to only have a sealing function; the tensile force generated by methane and tearing force formed by typhoon are all transferred to the rope net to reduce the generation of the situation that the gas storage cover film is broken and torn, so that the project operation service life is prolonged; therefore, the problem that an original black film methane tank gas storage cover film is easy to be torn and broken is solved.
Description
The epiphragma fixed network the present invention relates to, that a kind of installation covers the device above black film methane-generating pit gas storage epiphragma, surrounding is fixed with spud pile, utilize spud pile to tighten netting, gas storage epiphragma below netting is limited within the scope of certain altitude, and gas storage epiphragma only plays sealing function, and the power of tearing that the pressure that biogas produces and typhoon form is all married again on netting, reduce the breakage of gas storage epiphragma and Splitting and occur, extended the operation life of engineering.
Background technology
Anaerobically fermenting engineering in the dirty treatment process of the excrement of south China cultivation is at present all a kind of large-scale black film methane-generating pit of investment construction substantially.It is to adopt the gas storage epiphragma covering on methane-generating pit as gas storage space that biogas stores, when producing a certain amount of biogas, gas storage epiphragma surface-area can reach 3000 square metres of left and right, in the middle of dome-type, vertex can reach 7 meters, the power of the tearing reason that the pressure that biogas produces and typhoon sky form, cause epiphragma to tear damaged condition and happen occasionally, had a strong impact on black film methane-generating pit work-ing life, to breeding enterprise, bring certain financial loss.
Through technical study and practical experience combination, present inventor has researched and developed, and a kind of installation covers the epiphragma fixed network above black film methane-generating pit gas storage epiphragma.Utilize epiphragma fixed network that gas storage epiphragma is limited within the scope of certain altitude, make gas storage epiphragma only play sealing function, the power of tearing that the pulling force that biogas produces and typhoon form is all born by epiphragma fixed network, reduce gas storage epiphragma and tear damaged situation generation, extend the engineering operation life-span, solved the easily damaged problem with tearing of black film methane-generating pit gas storage epiphragma.
Summary of the invention
The present invention seeks to solve the mass defect that existing black film methane-generating pit gas storage epiphragma exists, a kind of epiphragma fixed network of invention, has guaranteed gas storage epiphragma during storing biogas and during typhoon severe weather, has avoided tearing damaged situation and occur, and extends the engineering operation life-span.
The present invention realizes by following technology: epiphragma fixed network, mainly comprises netting and spud pile.Described netting is to adopt high strength cord woven mesh structure, installs and covers above black film methane-generating pit gas storage epiphragma, and surrounding is fixed with spud pile.Utilize spud pile to tighten netting, the gas storage epiphragma below netting is limited within the scope of certain altitude.
Above-described epiphragma fixed network, its described netting is to adopt high strength cord woven mesh structure, installs and covers above black film methane-generating pit gas storage epiphragma, surrounding is fixed with spud pile.
Above-described epiphragma fixed network, it is described is to utilize spud pile to tighten netting, gas storage epiphragma below netting is limited within the scope of certain altitude, makes gas storage epiphragma only play sealing and do use, the power of tearing that the pulling force that storage biogas produces and typhoon severe weather cause is all married again on netting.
The present invention has the following advantages compared with prior art:
(1) in the present invention, netting is to adopt high strength cord woven mesh structure, the cheap practicality of whole device laid down cost.
(2) the present invention installs to cover above black film methane-generating pit gas storage epiphragma, and surrounding is fixed with spud pile, easy construction safety.
(3) the present invention utilizes the netting of tightening to bear the pulling force of biogas generation and the power of tearing that typhoon severe weather causes, and principle is simply efficient.

Fig. 2 is sectional view of the present invention.
1-netting 2-spud pile 3-gas storage epiphragma 4-biogas 5-fermentation liquid level 6-soil layer wherein
Embodiment
Now, by reference to the accompanying drawings to the specific embodiment of the invention, further describe as follows:
From Fig. 1 and Fig. 2, the present invention is a kind of epiphragma fixed network, mainly comprises: 1-netting 2-spud pile.3-gas storage epiphragma 4-biogas 5-fermentation liquid level 6-soil layer in figure is the total same characteristic features of black film methane-generating pit, is therefore not described further.Netting 1 is high strength cord material woven mesh structure, installs and covers above black film methane-generating pit gas storage epiphragma 3, and surrounding is fixing with spud pile 2.
Planner of the present invention, to wastewater treatment black film methane-generating pit, has carried out effective technological innovation invention, and the ground production run that makes it to guarantee both quality and quantity, has guaranteed the engineering operation life-span.As can be seen from Figure 2 the principle of work of this invention epiphragma fixed network: be mainly when biogas 4 produces, gas storage epiphragma 3 jack-up upwards, when gas storage epiphragma 3 highly rises to four meters of left and right, installation covers gas storage epiphragma 3 netting 1 above, by fixing pulling of spud pile 2 of surrounding, netting 1 is tightened comprehensively, stopped effect of increasing, push down gas storage epiphragma 3 below, the gas storage epiphragma 3 that can rise to seven meters originally, be limited in four meters of height, the power of tearing that the pulling force that whole biogas produces and typhoon cause is all married again on netting 1.Solved black film methane-generating pit gas storage epiphragma 3, originally damaged problem is easily torn in existence.
By above description, can find out that the present invention is in energy environment protection technical field, through certain invention achievement of putting into practice, constantly groping research and innovation.
