Abstract

The utility model relates to a heat preservation inner layer structure of low temperature storage tank with leak and track function, it is including laying one deck net (3) and half tub (4) on the jar body (1) surface, net (3) is placed on the jar body (1) surface laxly, makes its and jar body (1 a) surface leave the clearance, half tub (4) cover in jar body surface weld joint's top, these half tub (4) bottom both ends and jar body (1 a) fixed surface, bottom half tub (4) middle and welding seam (2) leave the clearance, the spraying has foam (5) between surface and the mesh of net (3), and the clearance is still left with netting in the jar body (1) surface after the spraying between (3). This kind of heat preservation inner layer structure of low temperature storage tank with leak and track function laid before conventional heat preservation, can play and confirm to leak regional effect to when revealing the next restoration jar body because of cryogenic liquids, also needn't all demolish the heat preservation again, saved the cost, the while heat preservation is the spraying convenience again, and the heat preservation is difficult for the fracture.

Description

There is the insulation endothecium structure of the low-temperature storage tank of leakage tracking function
Technical field
The utility model is related to a kind of insulation endothecium structure of the low-temperature storage tank with leakage tracking function, as liquefied gas Heat-insulation layer Deng low-temperature storage tank uses.
Background technology
In the liquefied gas carrier of ocean, as the visual plant of storage liquefied gas at low temp, such as lng(-163 DEG C), leg (- 102 DEG C), lpg(-48 DEG C) storage tank etc., the surface of these tank bodies is all coated with heat-insulation layer to play heat-insulating and sealing and insulation Effect, can effectively prevent cryogenic liquid seepage simultaneously.
Traditional heat preservation method is to reach heat insulation effect using the prefabricated cystosepiment of installation, because storage tank is that welding is assembled Form, cryogenic liquid leakage easily occurs at can seam, once tank surface leaks the insulation it is necessary to by tank surface Layer all knocks out, and finds leakage point.Therefore so just have the disadvantage that
1st, original heat-insulation layer is monoblock cystosepiment, is difficult quickly and accurately to find leak point, once leakage will all be removed, Cost is led to improve.
2nd, cystosepiment is reinstalled needs to consume more man-hour.
3rd, original cystosepiment easily ftractures when using.
Content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one kind rapidly and accurately can find leakage region, Reduce the insulation endothecium structure of the low-temperature storage tank with leakage tracking function of cost.
The purpose of this utility model is achieved in that
A kind of insulation endothecium structure of the low-temperature storage tank with leakage tracking function, it includes be laid on tank surface one Layer net and semicanal, described net is loosely placed at tank surface so as to leave gap with tank surface, semicanal covers in tank body table Above the weld seam of face, this half bottom of the tube two ends is fixed with tank surface, leaves gap, the table of described net with weld seam in the middle of half bottom of the tube It is coated with foam, net is fixed on tank body described foam, between face and mesh between the tank surface after spraying and net still Leave gap.
Described net is antifreezing protection net.
Described net is steel wire, glass web or carbon fibre web.
Described net is single mesh, or is spliced for multi-disc net.
Described semicanal is cystosepiment.
Compared with prior art, the beneficial effects of the utility model are:
Before the insulation endothecium structure of this low-temperature storage tank with leakage tracking function is laid on conventional heat-insulation layer, permissible Play the effect determining leakage region, and when revealing to repair tank body because of cryogenic liquid, also need not be whole by heat-insulation layer again Remove, save cost, heat-insulation layer sprays conveniently again, and heat-insulation layer is not easy to crack simultaneously.
Brief description
Fig. 1 has the structural representation of the insulation endothecium structure of the low-temperature storage tank of leakage tracking function for the utility model.
Wherein: tank body 1, weld seam 2, net 3, semicanal 4, foam 5.
Specific embodiment
Referring to Fig. 1, the utility model is related to a kind of insulation endothecium structure of the low-temperature storage tank with leakage tracking function, bag Include the one layer of net 3 being laid on tank body 1 surface and the semicanal 4 with heat insulation effect, the material of described semicanal 4 is similar with warming plate.
Described net 3 can be the antifreezing protection nets such as steel wire, glass web or carbon fibre web, and described net 3 can be single mesh, Or it is spliced for multi-disc net, described net 3 is loosely placed at tank body 1 surface so as to leave gap with tank body 1 surface.
There is a plurality of weld seam 2 on tank body 1 surface, and semicanal 4 covers above weld seam 2, and described semicanal 4 is preferably cystosepiment, should be partly Pipe 4 bottom two ends and tank body 1 surface are fixed, and leave gap with weld seam 2, this gap is used for being passed through nitrogen in the middle of semicanal 4 bottom, when When having liquid nitrogen or other liquid leakages, in this gap, the liquid leakage detection means of setting can detect, so that it is determined that leakage Region.
It is coated with foam 5, net 3 is fixed on tank body 1 described foam 5 between the surface of described net 3 and mesh, and tank Gap is still left, the effect in this gap is between body 1 surface and net 3: when there is liquid leakage on tank body 1 surface in non-commissure, Liquid can be guided by net 3, and then flows in semicanal 4 and the gap of tank body 1, is subsequently detected by liquid leakage detection means, really Determine leakage region.
Before the insulation endothecium structure of this low-temperature storage tank with leakage tracking function is laid on conventional heat-insulation layer, permissible Play the effect determining leakage region, and when revealing to repair tank body because of cryogenic liquid, also need not be whole by heat-insulation layer again Remove, save cost, heat-insulation layer sprays conveniently again, and heat-insulation layer is not easy to crack simultaneously.
