Abstract
The utility model relates to a thermal-insulating technique for underwater oil storage, more specifically to a thermal-insulating air cushion for a separated underwater oil storing device for replacing oil and water. The utility model comprises a flat air sac, an air supplementing tank and an air supplementing pipe, wherein the flat air sac is arranged in an underwater oil storing container for replacing oil and water and is connected with oil and water separating cloth; the air supplementing tank is connected with the flat air sac through the air supplementing pipe. The outer skins of the flat sac are made of soft gastight materials with low elasticity, and spacing pull ropes are uniformly arranged between the upper outer skin and the lower outer skin. The utility model can evidently reduce heat lost via the oil-water interface in the process of underwater oil storage for replacing oil and water. Thus, the utility model is suitable for the underwater storage of crude oil whose coagulation point is higher than the environmental water temperature.
Description
Technical field:
The utility model belongs to the marine petroleum development field, develops a kind of isolated oil and water displacement Fuel Tanking Unit thermal insulation air-cushion under water.
Technical background:
Oil storage technology under water is divided into oil and water displacement formula, oil gas displaced type two big classes.Oil and water displacement greatly reduces the suffered buoyancy of storage tank to be changed, and in the Gulf of Mexico, all there is application in the North Sea, economic benefit is good.China Dalian University of Technology etc. carried out oil and water displacement research, and had obtained patent " oil-water displacement process of storage crude oil with high solidifying point " (CN 85 1 02598 B), but did not take the insulation measure, and there is big thermal loss in oil-water interface.My unit has developed isolated oil and water displacement oil storage technology under water, adds one deck profit isolation cloth under water in the storage tank, and crude oil and extraneous seawater are separated fully, has eliminated the pollution to seawater fully, but still has the oil-water interface heat dissipation problem.The utility model is exactly on isolated oil and water displacement oil storage technical foundation under water, the novel heat insulation technology of exploitation.
Summary of the invention:
The purpose of this utility model is a kind of isolated oil and water displacement of exploitation Fuel Tanking Unit thermal insulation air-cushion under water.This air cushion comprises flat air bag, air supply tank, tonifying Qi pipeline; Flat air bag is arranged in oil and water displacement oil vessel inside under water, links to each other with the profit isolation cloth; Air supply tank links to each other with flat air bag by the tonifying Qi pipeline.The crust of flat air bag is made by the gastight material of soft low elasticity, uniform spacing stay cord between the two-layer up and down crust.Between oil and water, form one deck air cushion behind the flat airbag aeration, carry out heat-insulation and heat-preservation effectively.
The utlity model has following advantage:
(1) between oil and water, forms one deck air cushion, carry out heat-insulation and heat-preservation effectively.
(2) adopt the flat air bag of inner stay cord to keep consistency of thickness everywhere substantially, guarantee effect of heat insulation.
(3) under water in the oil and water displacement working environment, crude oil, extraneous hydraulic pressure keep in a basic balance, in the flat air bag as long as keep being equal to or a little more than the pressure of working environment, less demanding to flat air bag crust intensity and air-tightness, the gas volumes of extravasation result is very low in the flat air bag, after the inflation, can adopt nitrogen gas cylinder etc. to carry out the work tonifying Qi fully first.
(4) flat air bag possesses better flexibility, and the distortion comformability is good, can cooperate employing with the profit isolation technology easily, can not be subjected to being attached to the influence of the oil product that condenses on the oil vessel wall.
Description of drawings:
Fig. 1 is an isolated oil and water displacement Fuel Tanking Unit thermal insulation air-cushion principle of work scheme drawing under water
1, flat air bag 2, air supply tank 3, tonifying Qi pipeline
4, oil and water displacement oil vessel 5, profit isolation cloth
6, crust 7, spacing stay cord
The specific embodiment:
Now, the utility model is further described in conjunction with Figure of description: the thermal insulation air-cushion according to heat insulation requirement design suitable thickness, crust 6 and inner spacing stay cord 7 are connected, make air bag 1.Carry out behind the air tightness test gas in the flat air bag 1 of emptying, be installed on oil and water displacement oil vessel 4 inside under water, link to each other respectively with profit isolation cloth 5, tonifying Qi pipeline 3; Flat air bag 1 sinks under the water with oil and water displacement oil vessel under water, is inflated to working environment pressure in flat air bag 1.In the oil and water displacement process, flat air bag 1 forms one deck air cushion with the oil-water interface changing position between oil and water, carry out heat-insulation and heat-preservation effectively.A small amount of gas that flat air bag oozes out is replenished by tonifying Qi pipeline 3 at any time by air supply tank 2.
Claims (2)
1, isolated oil and water displacement Fuel Tanking Unit thermal insulation air-cushion under water comprises flat air bag (1), air supply tank (2), tonifying Qi pipeline (3); It is characterized in that flat air bag (1) is arranged in oil and water displacement oil vessel (4) inside under water, links to each other with profit isolation cloth (5); Air supply tank (2) links to each other with flat air bag (1) by tonifying Qi pipeline (3).
2, isolated oil and water displacement according to claim 1 Fuel Tanking Unit thermal insulation air-cushion under water is characterized in that the crust (6) of flat air bag (1), is made uniform spacing stay cord (7) between the two-layer up and down crust (6) by the gastight material of soft low elasticity.
