Description
Technical field
The utility model relates to a kind of natural gas storage tank peculiar to vessel being provided with vacuum heat-insulation interlayer, belongs to storage tank manufacturing technology field.
Background technique
This novel energy of rock gas has clean, environmental protection, efficiently feature compared with other primary energy, will by natural gas transportation to making land used, generally pipeline transport can be adopted, or the traffic tool, as fuel tank, ship etc. transport, if rock gas is transported by country over strait, be just merely able to be transported by ship.Rock gas is mainly based on methane, methane is a kind of gas, conveniently store transport, usually methane liquefaction is become liquid, like this, storage tank needs the state remaining on a low temperature, therefore, can be provided with insulating sandwich in storage tank, thermal-protective material is filled with in insulating sandwich, but, find in actual applications, only adopt insulating sandwich not good to the heat insulation effect of storage tank, if insulating sandwich is arranged thicker in strengthen heat insulation effect, the volume of storage tank will be made very huge, and the rock gas of storage is limited, is also not easy to installation and transportation.
Model utility content
For solving the problem, the utility model provides a kind of structure simple, easy to use, the natural gas storage tank peculiar to vessel being provided with vacuum sandwich of high insulating effect.
The technological scheme that the utility model adopts for its problem of solution is:
Be provided with a natural gas storage tank peculiar to vessel for vacuum heat-insulation interlayer, comprise inner casing and shell, between described inner casing and shell, be provided with the insulating sandwich of filling heat insulator; Be plugged with vacuum-pumping tube in described insulating sandwich, one end of described vacuum-pumping tube is positioned at insulating sandwich, and the other end is positioned at housing exterior, its tube wall is provided with the through hole that several are communicated with vacuum-pumping tube and insulating sandwich; The outer circumferential face of described vacuum-pumping tube is wound with copper mesh layers and nylon layer of cloth; Described copper mesh layers and nylon layer of cloth cover on these several through holes.
Preferably, the outer circumferential face of described vacuum-pumping tube is wound with copper mesh layers, nylon layer of cloth and copper mesh layers from the inside to the outside.
Further, described copper mesh layers, nylon layer of cloth and iron wire stratum reticulare adopt spiral form to be wrapped on vacuum-pumping tube outer circumferential face.
Further, the helical wound pitch of described copper mesh layers, nylon layer of cloth is less than or equal to 80mm.
The beneficial effects of the utility model are: be filled with thermoinsulation material in insulating sandwich, coordinate vacuum effectiveness, improve heat-insulating property further.Copper mesh and the nylon cloth alternately wrapping of certain order number is adopted, to realize evenly vacuumizing and prevent thermoinsulation material from releasing from through hole outside vacuum-pumping tube.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is internal structure sectional view of the present utility model;
Fig. 2 is the winding schematic diagram of the utility model vacuum-pumping tube.
In figure: 1, inner casing; 2, shell; 3, insulating sandwich; 4, tube wall; 5, vacuum-pumping tube; 6, through hole; 7, copper mesh layers; 8, nylon layer of cloth; 9, renovate.
Embodiment
A kind of natural gas storage tank peculiar to vessel being provided with vacuum heat-insulation interlayer as described in Figure 1, comprise inner casing 1 and shell 2, the insulating sandwich 3 of filling heat insulator is provided with between described inner casing 1 and shell 2, be expansion pearlite thermal insulation material in insulating sandwich 3, shell 2 is provided with renovates 9 for filling heat insulator in insulating sandwich 3.Be plugged with vacuum-pumping tube 5 in described insulating sandwich 3, one end of described vacuum-pumping tube 5 is positioned at insulating sandwich 3, and it is outside that the other end is positioned at shell 2, its tube wall 4 is provided with the through hole 6 that several are communicated with vacuum-pumping tube 5 and insulating sandwich 3.Shell 2 is carbon steel cylinders, improves the intensity of shell 2, is the guarantee maintaining laminated vacuum thermal insulation.The outer circumferential face of described vacuum-pumping tube 5 is wound with copper mesh layers 7 and nylon layer of cloth 8; Described copper mesh layers 7 and nylon layer of cloth 8 cover on these several through holes 6.Be filled with thermoinsulation material in insulating sandwich 3, coordinate vacuum effectiveness, improve heat-insulating property further.Copper mesh and the nylon cloth alternately wrapping of certain order number is adopted, to realize evenly vacuumizing and prevent thermoinsulation material from releasing from through hole 6 outside vacuum-pumping tube 5.
In order to improve the anti-leakage of thermoinsulation material further, as shown in Figure 2, the outer circumferential face of described vacuum-pumping tube 5 is wound with copper mesh layers 7, nylon layer of cloth 8 and copper mesh layers 7 from the inside to the outside.Further, described copper mesh layers 7, nylon layer of cloth 8 and iron wire stratum reticulare adopt spiral form to be wrapped on vacuum-pumping tube 5 outer circumferential face, and spiral lamination lap-joint nylon band is tightened.Further, the helical wound pitch of described copper mesh layers 7, nylon layer of cloth 8 is less than or equal to 80mm.Finally use iron wire, prick outside copper mesh with the spacing of about 100mm.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
