Description
Technical field
The present invention relates to storage facilities field, be specifically related to a kind of carbon dioxide storage tank.
Background technique
Produce a large amount of carbon dioxide in alcoholic fermentation process, these carbon dioxide, through purifying, liquefaction, canned, leave in factory, for use.The storage of carbon dioxide is usually under liquid condition, but the state of the carbon dioxide of post liquefaction is very unstable, the pressure needing to ensure in holding vessel remains in a stable scope, overpressure carbon dioxide can be become solid-state from liquid state, hypotony, liquid carbon dioxide gasification is then easily made to become gaseous carbon dioxide, carbon dioxide is in the process of gasification, the pressure increase in holding vessel can be made again, cause liquid carbon dioxide to become solid-state, how to ensure that holding vessel internal pressure is stable very important.In the middle of existing, for ensureing that the pressure in holding vessel does not rise, directly the gaseous carbon dioxide in holding vessel be discharged in air, not only environment impacted, also causing waste.
Summary of the invention
Technical problem to be solved by this invention is to provide one can ensure that tank internal pressure is stablized, and avoids generating solid carbon dioxide, avoids waste, the carbon dioxide storage tank that Alcohol Plant is special.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Carbon dioxide storage tank, comprises the tank body offering liquid entering hole and liquid outlet, and described tank body is provided with control module and detects the pressure gauge of tank body internal pressure, and this pressure gauge is connected with the input end of control module; Tank body also offers gas recovery port, and this gas recovery port is connected by the import of recovery tube with outside gas-liquid separator, and recovery tube is provided with pneumatic valve, and this pneumatic valve is connected with the output terminal of control module; The manometric delivery value of described control module real-time reception, when this delivery value is greater than predefined value, control module sends a signal to pneumatic valve, is opened by pneumatic valve.
Conveniently the liquid carbon dioxide in holding vessel is conveyed on special carbon dioxide waggon, in such scheme, described liquid outlet is connected with liquid-phase tube, this liquid-phase tube is provided with and fills car pump.
In such scheme, described tank body is also connected with gas phase pipe, this gas phase pipe is provided with gas phase valve.
In such scheme, the predefined value of described control module is 2.0MPa.
In such scheme, described recovery tube is also provided with emptying valve.
Compared with prior art, the present invention has the following advantages:
1, recovery tube, barometer and control module is added, when the pressure in holding vessel is higher than predefined value, control module opens pneumatic valve automatically, gaseous carbon dioxide in holding vessel is passed through recovery tube, send in gas-liquid separator, not only avoid environment, also carried out recycling.
2, existing holding vessel is all by angle of inclination, and liquid carbon dioxide is sent into transfer cart, there is inefficient defect like this, invention increases and fills car pump, can being filled with in car by filling car pump, greatly improving working efficiency by liquid carbon dioxide pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of carbon dioxide storage tank of the present invention.
Number in the figure is: 1, control module; 2, pressure gauge; 3, recovery tube; 4, pneumatic valve; 5, liquid-phase tube; 6, car pump is filled; 7, gas phase pipe; 8, gas phase valve; 9, liquid inlet pipe; 10, liquid flowing valve; 11, liquid phase valve; 12, emptying valve.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
A kind of carbon dioxide storage tank of the present invention, be mainly used in storing liquid carbon dioxide in Alcohol Plant, in Alcohol Plant, a large amount of carbon dioxide is produced in alcoholic fermentation process, successively by gas-liquid separator, compressor, purifier, exsiccator, condenser and purifying column, gaseous carbon dioxide purifying is liquefied, to reach usage requirement, to reinstall in holding vessel.
As shown in Figure 1, carbon dioxide storage tank comprises the tank body offering liquid entering hole and liquid outlet, and described liquid entering hole is exported with outside purifying column by liquid inlet pipe 9 and is connected, and liquid inlet pipe 9 is provided with liquid flowing valve 10.Described tank body is provided with control module 1 and detects the pressure gauge 2 of tank body internal pressure, and this pressure gauge 2 is connected with the input end of control module 1; Tank body also offers gas recovery port, and this gas recovery port is connected with the import of outside gas-liquid separator by recovery tube 3, and recovery tube 3 is provided with pneumatic valve 4 and emptying valve 12, and this pneumatic valve 4 is connected with the output terminal of control module 1; The delivery value of described control module 1 real-time reception pressure gauge 2, when this delivery value is greater than predefined value, control module 1 sends a signal to pneumatic valve 4, is opened by pneumatic valve 4.Described control module 1 according to the size of tank internal pressure, can also regulate the aperture of pneumatic valve 4, to control the size of gas flow rate, and then can control the pressure in tank more accurately, realizes accurately controlling.
Liquid outlet on holding vessel can be arranged on the bottom of tank body, then the angle that tilts, and is exported on transfer cart by the liquid carbon dioxide in tank.Also liquid outlet can be opened in the random position of tank body, then in the present embodiment, be opened in the side of tank body.Liquid outlet is connected with liquid-phase tube 5, this liquid-phase tube 5 is provided with and fills car pump 6 and liquid phase valve 11, described tank body is also connected with gas phase pipe 7, this gas phase pipe 7 is provided with gas phase valve 8.Such design, does not need to arrange angle of inclination, when entrucking, only needs gas phase pipe 7, liquid-phase tube 5 carried out being connected with the gas phase pipe 7 on car, liquid-phase tube 5 respectively and open gas phase valve 8, liquid phase valve 11.As long as open and fill car pump 6, just the liquid carbon dioxide in tank can be exported on transfer cart.
The predefined value of described control module 1 can set according to the requirement of holding vessel, and in the present embodiment, predefined value is 2.0MPa.
