Abstract
The utility model discloses a low-temperature storage tank. The low-temperature storage tank comprises an outer housing, wherein an inner container group is further arranged inside the outer housing; the inner container group consists of a plurality of inner containers; all inner containers of the inner container group are communicated with each other by a pipeline, and are communicated with the outside by a single valve group. The plurality of inner containers are fixed in the outer housing in a compact manner, so that the size of the low-temperature storage tank with the same capacity is reduced, therefore, the low-temperature storage tank is convenient to mount and transport. Meanwhile, the plurality of inner containers are connected to one valve group in a unified manner, so that the number of the valve groups is reduced, and the cost is lowered.
Description
Technical field
The present invention relates to a kind of low-temperature storage tank, belong to field of sealing technology.
Background technique
Vacuum insulation deep cooling pressurized container (low-temperature storage tank) is mainly used in storage, transfer of cryogenic liquid gas as deep cooling mediums such as liquid oxygen, liquid nitrogen, LNG Liquefied natural gas, current low-temperature storage tank is comprised of inner bag and shell double layer construction, inner bag stores liquefied gas at low temp, and the interlayer between inner bag and shell adopts the mode of high vacuum multi-lay winding or vacuum filling pearlife to carry out adiabatic heat-insulation.
Because it is very high for adiabatic requirement to store deep cooling medium, adopting double layer construction high vacuum interlayer is ideal adiabatic method, but at some special occasions, as the user needs again to use in the situation of many low-temperature storage tanks because fabricating yard is narrow and small simultaneously, the double layers of tank body of each low-temperature storage tank will take valuable usage space, also limit the storage volume of cryogenic media.
At some special occasions, due to the restriction of setting height(from bottom), for meeting the gas consumption demand, the user can only install the low-temperature storage tank of a plurality of minor diameters side by side.Restriction due to the double layers of tank body structure of low-temperature storage tank itself, a plurality of storage tanks are installed side by side, the sandwich portion of every storage tank will be wasted installing space, simultaneously outer tank self material used is also more, and each storage tank must, with a set of complete valve group, further increase user's user cost.
Summary of the invention
Goal of the invention: the present invention proposes a kind of low-temperature storage tank, saves installing space and reduces costs.
Technological scheme: the technical solution used in the present invention is a kind of low-temperature storage tank, comprises shell, and described enclosure also is provided with the inner bag group, and this inner bag group is comprised of a plurality of inner bags.
As a modification of the present invention, all inner bags of described inner bag group all are interconnected by pipeline, and are in communication with the outside by single valve group.A plurality of inner bags in described inner bag group are arranged in a line.
As a modification of the present invention, described each outer surface of liner all is wound around multilayer aluminum foil paper or glass fiber paper.
As of the present invention, further improve, described inner bag is fixing in the enclosure by glass fibre reinforced plastics.The cross section of described shell is round rectangle.
Beneficial effect: the present invention, by by being fixed in a shell of a plurality of inner bag compactnesses, has dwindled the volume of the low-temperature storage tank of same capacity, has facilitated and has installed and transportation.A plurality of inner bag unifications are connected to a valve group simultaneously, have also reduced valve group quantity, reduced cost.

The cross-sectional view that Fig. 3 is the embodiment of the present invention 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiments only is not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of various equivalents of the present invention.
Embodiment 1: low-temperature storage tank is for storing cryogenic fluids, as liquid nitrogen, liquid oxygen, liquefied ammonia etc.This liquid has a wide range of applications industrial, therefore often needs long-distance transportation and low-temperature storage tank is installed in factory.Existing low-temperature storage tank adopts the double layer construction of shell inner bag, also is provided with the interlayer of adiabatic heat-insulation between the two.The present invention improves this low-temperature storage tank, and the inner bag group that will be comprised of six inner bags 2 is placed in the inside of a shell 1 simultaneously.Six inner bags fitly are in line, and each inner bag 2 is fixed on shell 1 internal surface by the glass fibre reinforced plastic support (not shown).The outer surface of inner bag 2 is wound around laminated glass fender paper 6 as thermal insulation layer.Distance between adjacent two inner bags 2 is identical with the spacing of existing low-temperature storage tank housing and inner bag.And the described laminated glass fender paper 6 that is wrapped in inner bag 2 outer surfaces is just in time filled the space between adjacent two inner bags 2 of full phase.Also leaving space between inner bag group and shell 1 is so-called adiabatic space, this adiabatic space state that is evacuated, and owing to existing without any material, adiabatic space also has good heat insulating function, can play good insulation effect.Spacing between shell 1 and inner bag group is identical with the spacing of existing low-temperature storage tank housing and inner bag.Can find out with existing low-temperature storage tank and compare, in the situation that identical inner bag quantity, the present invention is owing to a plurality of inner bags being placed in to shell 1 inside, and quantity and the surface area of minimizing shell 1.Simultaneously the compact arrangement of six inner bags 2 has also been saved the spacing between five existing low-temperature storage tank shells and inner bag.
Each existing low-temperature storage tank is furnished with an external valve group, for controlling in use the outflow of its inner cryogenic liquide.The present invention communicates with each other into an integral body by internal duct 3 by six inner bags, then unification is connected to an external valve group.So, saved the quantity of valve group.
Embodiment 2: in the present embodiment, the outer surface that is unified in the inner bag group is wound around laminated glass fender paper 6 as thermal insulation layer, and there is not glass fiber paper 6 in the gap between adjacent two inner bags 2.Other parts are identical with embodiment 1.
