Abstract
A kind of cold insulated cabinet connects liquid device, it mainly includes residual liquid vaporizer, multiple low-temperature liquid drain pipes, the bottom of described residual liquid vaporizer is provided with the steam inlet tube accessing steam, at least following low-temperature liquid drain pipe that has been sequentially arranged above at this steam inlet tube: liquid air delivery pipe, liquid nitrogen delivery pipe and loxygen discharge pipe；Cryogenic liquid boil-off gas outlet it is provided with at the top of residual liquid vaporizer；It is additionally provided with liquid argon delivery pipe on residual liquid vaporizer between described liquid nitrogen delivery pipe and loxygen discharge pipe, and is equipped with more than one layer cobblestone the most beneath of described residual liquid vaporizer；It has simple in construction, safe and reliable, rationally efficient, when can effectively prevent high-purity liquid from discharging simultaneously, drastically vaporized expanding, cause liquid to pour in down a chimney, it is to avoid produce and mutually pollute；The protection space division feature such as safely.
Description
Technical field
The utility model relates to a kind of cold insulated cabinet and connect liquid device, especially a kind of air separation plant that is used for is in emergency
Lower parking, in ice chest various cryogenic liquids discharge simultaneously, be likely to result in residual liquid vaporizer cryogenic liquid drastically expand generation pressure
Power, causes liquid to pour in down a chimney thus the cryogenic liquid in air separation plant is produced the cold insulated cabinet mutually polluted and connects liquid device.
Background technology
Residual liquid vaporizer is static equipment, is that the cryogenic liquid in air separation cooling box is discharged the protection device to the person, by not
Rust steel discharging tube and residual liquid vaporizer composition.Under operating conditions, temperature is up to-196 DEG C, and its performance is good for residual liquid vaporizer
Bad, directly influence space division safety when being in an emergency, to empty operating facilities.
Due to residual liquid vaporizer inlet only one of which or two, cause various cryogenic liquids, product liquid in ice chest
When discharging, various liquid simultaneously flow on manifold trunk simultaneously, produce various composite pollution, flow to residual liquid vaporizer the most again；But
It is cryogenic liquid heating, it is possible to cause residual liquid vaporizer cryogenic liquid drastically to expand generation pressure, cause liquid to pour in down a chimney, and right
Cryogenic liquid in space division, product liquid produces and mutually pollutes.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art to exist, and a kind of simple in construction is provided, safety can
Lean on, rationally efficient, when can effectively prevent cryogenic liquid from discharging, cryogenic liquid in ice chest is produced the cold insulated cabinet polluted simultaneously and connects liquid
Device.
The purpose of this utility model completes by following technical solution: a kind of cold insulated cabinet connects liquid device, and it is main
Including residual liquid vaporizer, multiple low-temperature liquid drain pipes, the bottom of described residual liquid vaporizer is provided with the steam of access steam and enters
Mouth pipe, at least following low-temperature liquid drain pipe that has been sequentially arranged above at this steam inlet tube: liquid air delivery pipe, liquid nitrogen discharge
Pipe and loxygen discharge pipe；Cryogenic liquid boil-off gas outlet it is provided with at the top of residual liquid vaporizer.
As preferably: be additionally provided with liquid argon row on the residual liquid vaporizer between described liquid nitrogen delivery pipe and loxygen discharge pipe
Put pipe, and be equipped with more than one layer cobblestone the most beneath of described residual liquid vaporizer.
This utility model belongs to improvements over the prior art, and it has simple in construction, safe and reliable, rationally efficient, can have
When effect prevents cryogenic liquid from discharging simultaneously, the liquid in ice chest is produced the features such as pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail: shown in Fig. 1, a kind of guarantor described in the utility model
Ice chest connects liquid device, and it mainly includes residual liquid vaporizer 1, multiple low-temperature liquid drain pipes；The bottom of described residual liquid vaporizer 1 sets
Being equipped with the steam inlet tube 2 accessing steam, at least following cryogenic liquid that has been sequentially arranged above at this steam inlet tube 2 discharges
Pipe: liquid air delivery pipe 3, liquid nitrogen delivery pipe 4 and loxygen discharge pipe 5；Cryogenic liquid evaporation it is provided with at the top of residual liquid vaporizer 1
Gas discharge outlet 6.
Shown in figure, on the residual liquid vaporizer 1 between liquid nitrogen delivery pipe 4 described in the utility model and loxygen discharge pipe 5
It is additionally provided with liquid argon delivery pipe 7, and is equipped with more than one layer cobblestone 8 the most beneath of described residual liquid vaporizer 1.
Embodiment: shown in Fig. 1, is steam inlet tube 2 bottom residual liquid vaporizer 1 described in the utility model, and other 4 are not
With liquid discharge pipe the most up, in different import modes in residual liquid vaporizer 1 upper shed.When liquid discharges when,
The steam pipe of residual liquid vaporizer 1 is opened, and steam enters residual liquid vaporizer 1, from bottom to top；The liquid discharge of liquid line, by upper
Walking downward, so abundant heat exchange, cryogenic liquid all vaporizes, and discharges from the top of residual liquid vaporizer 1.Even if producing vapour drastically
Changing, residual liquid vaporizer produces pressure, causes cryogenic liquid to flow backwards, is also that purity liquid with in ice chest tower pours in down a chimney, will not
Affect the purity of ice chest each liquid interior.
Claims (2)
1. cold insulated cabinet connects a liquid device, and it mainly includes residual liquid vaporizer, multiple low-temperature liquid drain pipes, it is characterised in that institute
State the bottom of residual liquid vaporizer and be provided with the steam inlet tube accessing steam, this steam inlet tube be sequentially arranged above to
Few following low-temperature liquid drain pipe: liquid air delivery pipe, liquid nitrogen delivery pipe and loxygen discharge pipe；Arrange at the top of residual liquid vaporizer
There is cryogenic liquid boil-off gas outlet.
Cold insulated cabinet the most according to claim 1 connects liquid device, it is characterised in that described liquid nitrogen delivery pipe and loxygen discharge
