Abstract
A kind of interlock of carbon dioxide storage tank, conveyance conduit, a benzene detector unit and the unstripped gas on-off control unit being connected with the carbon dioxide for foodstuff storage tank including a carbon dioxide for foodstuff storage tank and one end, the other end of conveyance conduit is communicated with the unstripped gas of food stage liquid carbon dioxide, the conveyance conduit is sequentially provided with the outlet of raw material gas inlet, benzene detection mouth, break-make installation portion and unstripped gas, benzene detector unit is installed in benzene detection mouth, and unstripped gas on-off control unit is installed in break-make installation portion.This utility model arranges benzene detector unit and unstripped gas on-off control unit by each in front and back on the unstripped gas transporting direction of food stage liquid carbon dioxide, when the benzene detector unit, to detect benzene content in unstripped gas exceeded, unstripped gas on-off control unit can carry out interruption conveying to conveyance conduit automatically, the response time of operator can be reduced, avoid the micro-benzene for being accidentally higher by standard from entering carbon dioxide for foodstuff storage tank, improve the product quality of carbon dioxide for foodstuff.
Description
Technical field
This utility model is related to the production of food stage liquid carbon dioxide and storage device, refers in particular to a kind of carbon dioxide
The interlock of storage tank.
Background technology
In the unstripped gas of food stage liquid carbon dioxide, it is that hydrocarbon in unstripped gas, benzene etc. have to human body the characteristics of which is maximum
The harmful impurity of poison all severe overweight, typically all exceed hundreds of or even thousand of times of index.Using purifying technique by impurity and dioxy
Changing carbon to be separated and recovered from, highly purified carbon dioxide being obtained through de- hydrocarbon, de-benzolized technology, gaseous carbon dioxide is pressurized to a level pressure
Power is simultaneously cooled down, and becomes liquid CO 2.But can be because artificial during the monitoring of daily on-line operation is detected
Factor causes response blunt and makes the micro-benzene for being accidentally higher by standard enter storage tank, has a strong impact on the product matter of carbon dioxide for foodstuff
Amount, to serious impact is brought in production.
Utility model content
This utility model provides a kind of interlock of carbon dioxide storage tank, and its main purpose is to overcome existing food
Fail to find the defect that benzene content is exceeded in time in the production and transportation of level liquid carbon dioxide.
To solve above-mentioned technical problem, this utility model is adopted the following technical scheme that：
A kind of interlock of carbon dioxide storage tank, including a carbon dioxide for foodstuff storage tank and one end and the food two
The conveyance conduit that carbonoxide storage tank is connected, the other end of the conveyance conduit are communicated with the raw material of food stage liquid carbon dioxide
Gas, above-mentioned interlock also include a benzene detector unit and a unstripped gas on-off control unit, and the conveyance conduit sequentially sets
There is the outlet of raw material gas inlet, benzene detection mouth, break-make installation portion and unstripped gas, the benzene detector unit is installed in the benzene detection
Mouthful, the unstripped gas on-off control unit is installed in break-make installation portion.
Further, the benzene detector unit is a benzene in-line analyzer.
Further, the unstripped gas on-off control unit includes a control piece and one is installed on the break-make installation portion
On stop valve, the Enable Pin of the stop valve is connected to the outfan of the control piece.
Further, the control piece is relay, and the Enable Pin of the relay is connected to the benzene in-line analyzer
Outfan.
Further, the outfan of the benzene in-line analyzer is also associated with a hazard warning flasher.
Compared to the prior art, the beneficial effect of this utility model generation is:
It is this utility model simple structure, practical, by the unstripped gas transporting direction in food stage liquid carbon dioxide
It is each before and after upper that benzene detector unit and unstripped gas on-off control unit are set, when the benzene detector unit detects benzene content in unstripped gas
Exceeded, unstripped gas on-off control unit can carry out interruption conveying to conveyance conduit automatically, it is possible to reduce during the response of operator
Between, it is to avoid the micro-benzene for being accidentally higher by standard enters carbon dioxide for foodstuff storage tank, improves the product quality of carbon dioxide for foodstuff.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is illustrated with reference to the accompanying drawings.
With reference to Fig. 1.A kind of interlock of carbon dioxide storage tank, including a carbon dioxide for foodstuff storage tank 1 and one end
The conveyance conduit 2 being connected with the carbon dioxide for foodstuff storage tank 1, the other end of the conveyance conduit 2 are communicated with food stage liquid
The unstripped gas of carbon dioxide, above-mentioned interlock also include a benzene detector unit 3 and a unstripped gas on-off control unit 4, institute
State conveyance conduit 2 and be sequentially provided with raw material gas inlet 20, benzene detection mouth 21, break-make installation portion 22 and unstripped gas outlet 23, it is described
Benzene detector unit 3 is installed in the benzene detection mouth 21, and the unstripped gas on-off control unit 4 is installed in break-make installation portion 22.
With reference to Fig. 1.In the present embodiment, the benzene detector unit 3 is preferably a benzene in-line analyzer 30.The unstripped gas
On-off control unit 4 preferably comprises a control piece and one is installed on the stop valve 40 on the break-make installation portion 22, described
The Enable Pin of stop valve 40 is connected to the outfan of the control piece.The control piece is preferably relay 41, the relay 41
Enable Pin be connected to the outfan of the benzene in-line analyzer 30.
With reference to Fig. 1.In addition, in the present embodiment, the outfan of the benzene in-line analyzer 30 is also associated with warning sudden strain of a muscle
Light lamp 31.When the numerical value of micro-benzene reaches alarm parameters, the warning output end of benzene in-line analyzer 30 inhales can relay 41
Close.While 41 adhesive of relay stop valve 40 before 1 import of carbon dioxide for foodstuff storage tank can be automatically switched off, while
Hazard warning flasher 31 starts alarm.Thus produce important interlocking effect, it is possible to reduce the response time of operator, it is to avoid even
The micro-benzene for being so higher by standard enters carbon dioxide for foodstuff storage tank 1, and notifies operator's process problem in time.When micro-benzene
When numerical value is less than alarm parameters again, after being eliminated to warning by operator, relay 41 will disconnect, while stop valve 40
Can open, it is ensured that qualified micro-benzene can timely enter carbon dioxide for foodstuff storage tank 1, it is ensured that high-quality carbon dioxide for foodstuff
Steady production.
