Abstract
The utility model discloses a storage tank for low-temperature liquid. The storage tank comprises a housing (1) and an inner cylinder (2) arranged in the housing (1), and is characterized in that steel pipes (3) are welded at the bottom of the side wall of the inner cylinder (2), supporting steel pipes (4) are welded at the inner bottom of the housing (1), and the steel pipes (3) and the supporting steel pipes (4) are connected through adiabatic pads (5). The storage tank is reasonable in design, simple in structure and wide in application range, and greatly reduces the heat transfer between the housing and the inner cylinder.
Description
Technical field
The utility model relates to a kind of cryogenic liquid tank for storage liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide and LNG etc.
Background technique
As everyone knows, at present, the cryogenic liquid tank that is used for storage liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide and LNG etc. comprises shell and places the interior inner core of shell, the in-built thermal-protective material of shell, fill liquid in the inner core, the top of inner core is by suspender belt 6, drawstring 7 and embrace and be with 8 fixingly (to see Fig. 1) in the enclosure.Suspender belt 6, drawstring 7 and embracing is with 8 to make by the S30408 steel, good heat conductivity, and shell is by suspender belt 6, drawstring 7 and embrace and be with 8 heat is delivered to inner core, so that the cryogenic liquide evaporation.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of heat transmission that reduces between inner core and the shell, reduces the cryogenic liquid tank of the static evaporation rate of cryogenic tank.
To achieve these goals, the technical solution of the utility model is as follows: a kind of cryogenic liquid tank, comprise shell (1) and place the interior inner core (2) of shell (1), be welded with steel pipe (3) in the bottom of inner core (2) sidewall, be welded with supporting steel pipe (4) at the inner bottom surface of shell (1), described steel pipe (3) is connected 4 with supporting steel pipe) connect by adiabatic backing plate (5) and bolt.
Adopt technique scheme, the bottom of inner core is fixing in the enclosure by steel pipe, supporting steel pipe, between steel pipe and supporting steel pipe, connect by adiabatic backing plate, adiabatic backing plate heat-conducting property is bad, this has just greatly reduced the heat transmission between shell and the inner core, so that cryogenic liquide steam output minimizing, thereby the static evaporation rate of reduction cryogenic tank.
In technique scheme, for convenient adiabatic backing plate is connected the connection of supporting steel pipe with steel pipe, the lower end surface of described steel pipe (3) is equipped with upper steel plate (9a), the upper-end surface of described supporting steel pipe (4) is equipped with lower steel plate (9b), the width of described upper steel plate (9a) is greater than the external diameter of steel pipe (3), the width of described lower steel plate (9b) is greater than the external diameter of supporting steel pipe (4), described adiabatic backing plate (5) is positioned between upper steel plate (9a) and the lower steel plate (9b), described upper steel plate (9a), the part symmetry that lower steel plate (9b) exceeds steel pipe (3) and supporting steel pipe (4) has bolt hole, have in the connection on the described adiabatic backing plate (5), lower two steel plates (9a, the through hole of bolt hole 9b), described adiabatic backing plate (5) and upper, lower two steel plates (9a, 9b) be bolted.
In technique scheme, be delivered to inner core for fear of the heat of shell by bolt, all be set with jacket (10) in the bolt hole of upper and lower two steel plates (9a, 9b).
Preferred as this programme, described steel pipe (3) is the S30408 Stainless Steel Tube.
Preferred as this programme, described supporting steel pipe (4) is No. 20 seamless steel pipes.
In technique scheme, in order to reduce heat transmission, described adiabatic backing plate (5) is phenolic aldehyde layer backing plate.
Beneficial effect: the utility model is reasonable in design, simple in structure, applied widely, greatly reduces the heat transmission between shell and the inner core.
