Jet mattress is that oil depot tank field intellectual analysis control process reclaim prevention safety interlock system or with the main supporting of purposes Device.Exactly jet mattress is put into tank body in figure（2）It is shown, in fluid layer figure（7）It is shown, in jet mattress figure（6） It is shown, above oil reservoir, Air-jet cushion top be air with the mixed gas figure of oil gas in（3）It is shown, just formed between gas and oil In one tunic figure（12）Shown, this tunic just effectively reduces the evaporation rate of crude oil, while effectively having separated oil tank Body fluid is contacted with the oxygen above oil reservoir.

Know-why：

Oil gas is raised when oil depot tank field changes with local climate, in oil depot tank body with temperature constantly to volatilize, if oil gas can not be equal The even quickly oxygen in tank body being taken out of carries out deoxygenation in tank body, same danger occur, is brought on a disaster to scene.Therefore we Jet mattress is utilized again, and on oil reservoir, the lower floor of jet mattress is a scalable resilient film of tool to bedding, works as jet mattress Air bag figure in（10）It is shown, ventilation just it is natural airbag wall is tightly coincide with tank body inwall together with, one annulus of formation, Or deformable irregular ring bodies.Devised in the range of barrier film during rational oil gas exchanges mouth figure（9）Shown, purpose is just It is that crude oil changes with local climate, in the oil gas figure of the interior formation of constantly being volatilized with temperature rising oil gas of oil depot tank body（3）It is shown, must The peripherad gas outlet in path that must pass through to specify carries out regular discharge；Oil gas exchanges mouth and also has a free-revving engine, just It is that crude oil has fluid to be emitted on jet mattress, it is necessary to certain hour could all flow with fluid during oil-feed or unloading Move together, this mouthful is flowed in convergence window figure together to fluid（7）It is shown,；So oil gas is by jet mattress Barrier film does not block crude oil vapor volatilization purpose, also oil, gas function of exchange only.Oil gas exchanges the arrangement distance of mouth with perforate In the range of 0.3 square metre, the size in each hole is defined centre distance general control by air bag with the wall of air bag.

On barrier film, the low side face of air bag is tightly connected the uniform cloth of air bag in jet mattress with barrier film, Cheng Bo Line type spirals, the gap of air bag and air bag in the range of 300 millimeters, the diameter of air bag between 200 millimeters to 100 millimeters, gas Air intake is connected to telescoping tube at the one of the outermost end of capsule, holds port sealing, end face to there is an air nozzle to be connected centered on end, Purpose is exactly that the oxygen at the dead angle that end is formed blows off.Air bag has Diaphragming air bag inside real with the pollution of extraneous gas simultaneously Ensure that the oxygenless gas in air bag are not disturbed by tank interior oxygen-containing gas.

Air bag uniform layout three rows of nozzles in jet mattress is as schemed（Oil gas interchange graph）It is shown, it is separately mounted to air bag In the surface uniform layout figure of the left and right sides and air bag（13）It is shown.When the oxygenless gas in oil gas volatilization out air bag just lead to Regular air nozzle is crossed to blow to around air bag in figure（15、17）It is shown, can be quickly with the oxygen above oil-yielding stratum by spray Valve blows out in the outer figure of tank body from bottom to top（5）It is shown,.So purge the carrier of oxygen that ensure that in oil tank and can nowhere hide and reach nothing The purging at dead angle, realizes comprehensive, zero dead angle the purging best approach.The jet method of nozzle is as schemed（Jet schematic diagram）Institute Show.Each jet osculum in air nozzle has in a unidirectional stop valve figure（16）Shown, oil gas, fluid cannot pass through Nozzle flow back into the function of inside air bag.

In telescoping tube figure（4）It is shown, be closely connected with the air bag of jet mattress together be supply air line important ring In section figure（1）Shown, purpose can be just the unloading or canned because of crude oil with jet mattress, jet mattress is freely swum in oil The optional position of layer, just only freely stretching for telescoping tube could run simultaneously this responsibility with jet mattress, otherwise, jet bed What pad cannot just be supplied is effectively ensured.
