Abstract
The utility model discloses a methane storage device made of the resin based composite material combined member, aiming to overcome the defects of heavy weight, low intensity, poor corrosion resistance, troubled installation and transportation, etc in the existing gas storage float hood made of the steel wire mesh concrete or the low carbon steel. The device is combined and assembled by the resin based composite material combined member; the integration is a hollow cylinder; the top is provided with a manhole; the bottom is provided with an annularly arranged balance weight disk; a balance weight is arranged on the balance weight disk. The utility model not only solves the defects of heavy weight, low intensity, poor corrosion resistance, troubled installation, etc in the existing gas storage float hood made of the steel wire mesh concrete or the low carbon steel, but also overcomes the technical problems adverse to use the methane storage device of small pressure, instability, etc existed in the direct adoption of the resin based composite material combined member. The float hood can be enabled to keep the gas storage pressure range with minor air pressure fluctuation. The problems of large difficulty of the float hood integral processing and inconvenient transportation are solved through the member combination mode.
Description
Technical field
The utility model belongs to the renewable energy source domain, relates to a kind of employing polymer matrix composites compostle member, is applied to the floating cover of biogas storage of middle-size and small-size biogas engineering.
Background technique
Methane storage device is an equipment important in the biogas engineering, and it is floating hood-shaped that common caisson is, and is installed on the cylindrical tank, changes moving up and down with gas-storing capacity.The storage air-float hood is generally hoped concrete or low carbon steel plate manufacturing with steel wire, on-the-spot processing.
Polymer matrix composites are to be made by composite materials such as unsaturated polyester resin, glass fiber cloth, curing agent, filler and additives, have in light weight, intensity is high, characteristics such as corrosion-resistant and easy for installation.Weight only is 1/5 of carbon steel, and tensile strength surpasses carbon steel, and anti-general soda acid, is widely used in fields such as chemical industry, environmental protection and cleaners and polishes in recent years.On the other hand, directly also have problems with the light polymer matrix composites production and processing storage air-float hood of matter material, so floating cover is difficult to maintenance certain pressure and pressure stability, is unfavorable for that biogas uses.
Summary of the invention
The utility model is intended to overcome the existing matter that is existed by the storage air-float hood of steel-wire-net reinforced concrete or low carbon steel making and weighs, intensity is low, corrosion-resistant, install, transport defectives such as trouble, a kind of methane storage device that adopts the polymer matrix composites compostle member to make is provided, and solves and directly use pressure transient that polymer matrix composites exist etc. to be unfavorable for the technical problem that methane storage device uses.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
The polymer matrix composites methane storage device is characterized in that: formed by polymer matrix composites compostle member composite assembly, integral body is the cylindrical of hollow, and the top is provided with manhole, and described compostle member comprises the cover plate for manhole at side plate and top.
This bottom of device is provided with balancing disk, settles counterweight on it.
Described balancing disk is arranged on the circumference of side plate bottom ringwise.
Described compostle member is made of 2-12 piece side plate and a cover plate for manhole.
Described compostle member thickness is 5-20mm.
The utility model makes it have following beneficial effect owing to adopt above technological scheme:
The utility model adopts the polymer matrix composites compostle member to make the floating cover of biogas storage, and bottom floating cover, balancing disk is set, with cheap precast concrete block or fragment of brick as counterweight, thereby heavy, the defectives such as intensity is low, corrosion-resistant, installation trouble of the matter that the storage air-float hood that had both solved the making of steel-wire-net reinforced concrete or low carbon steel exists, the pressure that has overcome direct employing polymer matrix composites compostle member existence again is little, instabilities etc. are unfavorable for the technical problem that methane storage device uses, and make floating cover can keep the less gas storage pressure scope of air pressure fluctuation; By the component composition mode of novelty, it is big to have solved the whole difficulty of processing of floating cover, the problem that is not easy to transport; And select polymer matrix composites processing cheap, corrosion-resistant and that intensity is high, make product have the very strong practicability and the market competitiveness.The polymer matrix composites compostle member of floating cover is concentrated processing in the factory that fixes a point, convenient transportation of the member after the processing and installation on the spot, and product price only is half of other products.
