Background technology
At present; be applied to the iron storage tank of the widely used individual layer of buried tank of chemical industry, printing and dyeing, printing ink, petrol service station etc.; the iron storage tank of individual layer is when storing inflammable and explosive or toxic substance such as chemical solvent, oil; because there are factors such as physics corrosion and electrolytic corrosion in these dangerization product and toxic substance; after being corroded, the iron storage tank of common individual layer produces seepage; in case the generation seepage will be brought the serious consequence of environmental pollution or underground harm water resource.And, being subjected to phreatic corrosion and electrolytic corrosion because the iron storage tank of individual layer is embedded in undergroundly throughout the year, the iron storage tank of individual layer is in service property (quality) and tangible potential safety hazard is arranged service life, relates to safety, economy, environmental protection.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of buried double-deck storage tank is provided, and has very strong acid and alkali-resistance, and anti-electrolyte is difficult for seepage takes place, and the incomparable advantage of the iron storage tank of individual layer is being arranged aspect safety, economy, the environmental protection.
The purpose of this utility model is achieved in that a kind of buried double-deck storage tank, it comprises steel inner casing, small interlayer and FRP shell, small interlayer is the hollow layer that comprises thread adhesive tape and PET barrier film, thread adhesive tape is wound in the outside face of steel inner casing, the PET barrier film is wrapped in the outside of thread adhesive tape, and the FRP shell is coated on the outside face of PET barrier film.
It also comprises the remote monitor and control seepage detection system, is connected with the seepage inductor on the remote monitor and control seepage detection system, and described seepage inductor inserts the leak detection tube bottom from storage tank leak detection tube top, and is connected with the hollow layer of small interlayer.
Described thread adhesive tape is the glass fibre single-coated foam.
The outside face of described steel inner casing is coated with level anticorrosive paint peculiar to vessel, and described thread adhesive tape is wound in level anticorrosive paint outside face peculiar to vessel.
Thickness 〉=the 3.5mm of described FRP shell.
The hollow layer thickness of described small interlayer is 0.1～0.2mm.
Compared with prior art, the beneficial effects of the utility model are:
The buried double-deck storage tank of the utility model, comprise steel inner casing, small interlayer and FRP shell from inner casing successively to shell, buried double-deck storage tank with unique texture, even steel inner casing generation seepage, the combustible products such as chemical solvent, oil or the toxic substance that also can guarantee seepage storage in the storage tank only flow in small interlayer, can not leak into that the external boundary of storage tank can not pollute earthing water or soil jeopardizes environment, improve the safety factor of environmental protection.
The FRP shell be by the resin automatic coating machine with glass fiber yarn 360 ° of outer field spray mo(u)lding methods of PET barrier film that are sprayed on the outside face of small interlayer equably, avoid it directly to be coated in thread adhesive tape and can't form small interlayer.
Because the FRP shell has very strong resistance to acids and bases, anti-electrolyte, so should the bilayer storage tank as buried tank, be not vulnerable to earthing water and saltings, coastland yet and produce acid and alkali corrosion and electrolytic corrosion, improved the service property (quality) of buried double-deck storage tank and prolonged service life.
This buried double-deck storage tank also has been equipped with the remote monitor and control seepage detection system simultaneously; can carry out 24 hours complete monitorings to this buried double-deck storage tank; in case the inner or outside seepage that produces; the inductor of remote monitor and control seepage detection system can be in small interlayer produces during liquid level 〉=15mm reports to the police; guarantee user's very first time withdraw from use and reparation in time; fundamentally stopped inflammable and explosive or the extraneous possibility of toxic substance outflow, protected the potential safety hazard of earthing water and soil timely.
