Abstract
A metal nitrogen-filled environment-friendly storage tank with a double-layered wall belongs to the technical field of petroleum and chemical machinery. The metal nitrogen-filled environment-friendly storage tank with a double-layered wall is characterized in that a metal or glass fiber reinforced plastics inner container is fixed in an outer-layer tank of the metal or glass fiber reinforced plastics storage tank through a steel gasket, a closed cavity is formed between the outer-layer tank and the inner container of the storage tank, inert gas is filled in the closed cavity, and a pressure gauge communicated with the closed cavity is disposed on the outer-layer tank. The metal nitrogen-filled environment-friendly storage tank has the advantages of being capable of effectively controlling environmental pollution and damage and corresponding leakage loss due to leakage of the storage tank and effectively reducing volatilization and pollution loss or freezing loss of some petrochemical media due to temperature change. The service life of the storage tank is twice longer than that of a common single-layer steel oil tank.
Description
Technical field
The utility model belongs to oil, chemical machinery technical field.
Background technique
Buried or the land storage tank in all gas stations of China and some chemical plant all is the solid wall storage tank at present.When if this kind storage tank uses in buried mode, in case be difficult in time be found when seepage takes place.When the consequence that causes the serious filter loss of petrochemical industry medium and environment is done great damage, just be found; When if this kind storage tank uses on the ground, not only there is easy seepage, but also can causes waste and pollution in the atmosphere because of the outer natural temperature rising of storage tank causes some petrochemical industry medium to evaporate in a large number.
Summary of the invention
The purpose of this utility model is: provide a kind of metal crimp azo-cycle to protect the dual-layer wall storage tank, it has solved petrochemical industry or liquid chemical raw material storage tank because seepage, destroys and produce the problem of loss of bringing and bring to environment.
The technical solution of the utility model is: be fixed with metal or glass fibre reinforced plastics inner bag by steel plate washer in metal or the outer jar of glass fibre reinforced plastics storage tank, form a closed cavity between the outer jar of storage tank and the inner bag, be filled with inert gas in closed cavity, outer jar is provided with the pressure gauge that is communicated with closed chamber.
The beneficial effects of the utility model are: can control environmental pollution destruction and corresponding filter loss that tank leak is brought effectively; Can effectively reduce because of natural temperature changes and cause the volatilization pollution loss of some petrochemical industry medium or the loss of freezing.Be more than 2 times of common individual layer steel oil tank working life.
Description of drawings
Fig. 1 is the utility model structure sectional view.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, pressure gauge, the 2nd, pressure gauge, 3 personnel's access holes, the 4th, hoisting ring, the 5th, equipment mounting hole, the 6th, closed cavity, the 7th, steel plate washer, the 8th, the outer jar, the 9th of storage tank, metal or glass fibre reinforced plastics inner bag.
At first weld the metal or the glass fibre reinforced plastics inner bag 9 of a standard, two manholes and other equipment of storage tank of welding sufficient size on this metal or glass fibre reinforced plastics inner bag 9 are installed preformed holes.On outer wall, evenly weld the high steel plate washer 7 of 100mm then.This steel plate washer 7 is to be used in outer jar 8 inwall effect supporting storage tank.Make metal or the outer jar 8 of glass fibre reinforced plastics after welding steel plate washer.Outer jar 8 inwalls and inner bag 9 outer walls form the thick closed cavity 6 of 100mm.Near whole sealed cavity manhole, stay two 6 partial pressure tables 1 and 2 mounting holes.Nitrogen machine is pressed inflated with nitrogen inward by first 6 partial pressure table 1 mounting hole, and beginning is with nitrogen the air in the dual-layer wall chamber to be cemented out from second 6 partial pressure table mounting hole, after nitrogen replacement finishes in the dual-layer wall chamber, encapsulates second pressure gauge 2.Nitrogen machine continues to press inflated with nitrogen inward by first pressure gauge 1 mounting hole, encapsulation pressure gauge 1 when the nitrogen pressure in the dual-layer wall chamber reaches 0.2Mpa.Dual-layer wall welding in storage tank after two pressure gauge seals are intact completes.Carrying out other annexes making and japanning at last handles.
Pressure is sealed with charged sub-teletransmission pressure gauge or mechanical pressure gauge after filling 0.2MPa nitrogen in sealed cavity.Just can in time know whether seepage of the utility model storage tank by manometric variation directly perceived.Nitrogen is a kind of inert gas, spend-45+100 degree between physicochemical property stable.Nitrogen with pressure can prevent the burning corrosion in the dual-layer wall chamber in the utility model storage tank dual-layer wall chamber.Prolong the utility model storage tank working life.And utilize the slow characteristics of nitrogen thermal conductivity, in the dual-layer wall chamber, press the utility model storage tank of inflated with nitrogen to be incubated relatively.
Claims (1)
1. a metal crimp azo-cycle is protected the dual-layer wall storage tank, it is characterized in that: in metal or the outer jar of glass fibre reinforced plastics storage tank, be fixed with metal or glass fibre reinforced plastics inner bag by steel plate washer, form a closed cavity between the outer jar of storage tank and the inner bag, be filled with inert gas in closed cavity, outer jar is provided with the pressure gauge that is communicated with closed chamber.
