Description
Technical field
This utility model relates to a kind of device balancing extraction kettle inlet and outlet pressure, belongs to extraction kettle pressure release technical field.
Background technology
Pressure in the extraction kettles such as the extraction kettle in large industrialized supercritical extraction unit completes to extract after work, need
The kettle cover that can open extraction kettle after being reduced to 0MPa carries out discharging.
Most of extraction kettle working gas CO2It is from the air inlet of extraction kettle bottom, CO2Gas is fully contacted extraction with extraction material
After taking, give vent to anger from extraction kettle upper end.After solid material extraction kettle inner core in extraction kettle installs, it is placed in extraction kettle,
For ensureing effect of extracting, the outer surface of inner core upper end must be with extraction kettle inner core good seal.Therefore when being full of in extraction kettle
CO2Time, extraction kettle inner core bears external pressure.
In pressure leak process, owing to manual operations cannot accurately control opening of the valve opening of extraction kettle outlet pressure relief valve
Degree, causes pressure release " too fast ", and for the extraction kettle equipped with extraction material, " pressure release is too fast " can cause extraction kettle inlet pressure
Bigger than outlet pressure, thus cause extraction kettle inner core to be increased by external pressure, when inner core bear external pressure exceed certain limit time, inner core will
Can be deformed, even be stuck in extraction kettle, it is impossible to take out smoothly.If mentioning inner core by force, inner core cylindrical also can scratch extraction
Take still inwall, affect extraction kettle quality and service life.
In order to prevent inner core from deforming, current way be heat transfer effect is thickeied sufficiently thick, to ensure its pressure-bearing.But
Being that what inner core bore is external pressure, for the inner core of different-diameter, increase 1MPa external pressure, wall thickness need to increase more than 6mm, and this increases
Jia Liao manufacturing firm manufacturing cost, the increase of the weight of inner core simultaneously also brings inconvenience to the operation of user, and this problem is always
Seriously annoying user and manufacturer.
Summary of the invention
The purpose of this utility model is, it is provided that a kind of device balancing extraction kettle inlet and outlet pressure, in pressure leak process
Make inner core not pressurized or pressurized the least, to guarantee that inner core is not damaged, thus overcome the deficiencies in the prior art.
The technical solution of the utility model is achieved in that
A kind of device balancing extraction kettle inlet and outlet pressure of the present utility model, including the extraction kettle equipped with inner core, in extraction
Take still and be provided with original gas outlet, equipped with relief valve on original gas outlet, be provided with one at extraction kettle upper position and increase newly out
QI KOU, is provided with a balance pipe between newly-increased gas outlet and the air inlet of extraction kettle, and in balance pipe and newly-increased gas outlet
Junction be provided with balanced valve, the port of export of the intake valve of extraction kettle connects with air inlet and balance pipe.
Original gas outlet of the above-mentioned position height in the newly-increased gas outlet that extraction kettle upper position is arranged and extraction kettle
Position height is identical.
It is additionally provided with sealing ring between the top and extraction kettle of above-mentioned inner core.
Owing to have employed technique scheme, compared with prior art, this utility model is not in increasing for this utility model
In the case of barrel thickness, well solve the problem on deformation of extraction kettle inner core in pressure leak process.Therefore, this utility model is not only
Have and can be prevented effectively from inner core scratch extraction kettle inwall and extend the advantage in extraction kettle service life, but also have and can improve extraction
Take still quality, also can save the manufacture cost and other advantages of extraction kettle simultaneously.
Accompanying drawing explanation
Fig. 1 is method schematic diagram of the present utility model.
Being labeled as in figure: 1-extraction kettle, 2-inner core, 3-air inlet, the original gas outlet of 4-, 5-relief valve, 6-intake valve,
7-increases gas outlet, 8-balance pipe, 9-balanced valve, 10-sealing ring, 11-solid material newly.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as new to this practicality
Any restriction of type.
This utility model is to be constituted according to a kind of following method balancing extraction kettle inlet and outlet pressure, and the method is such as
Shown in Fig. 1, it is to increase a newly-increased gas outlet 7 on extraction kettle 1 top, is then provided with between newly-increased gas outlet 7 and air inlet 3
Article one, balance pipe 8, and balanced valve 9 is set in the junction of balance pipe 8 with newly-increased gas outlet 7；Before extraction kettle 1 pressure release, first
Open balanced valve 9, open relief valve 5 the most again, when formerly unlatching balanced valve 9 opens relief valve 5 the most again, preferably make to open to let out
The time of pressure valve 5 should lag behind more than the 10 seconds time opening balanced valve 9；So can make the CO between inner core and extraction kettle2
Enter extraction kettle 1 upper end by balance pipe 8, and without the solid material 11 in inner core, directly reach extraction kettle 1 and import and export pressure
Dynamic balance, prevents inner core 2 in pressure leak process from deforming scratch extraction kettle 1.
The of the present utility model a kind of device balancing extraction kettle inlet and outlet pressure constituted according to said method, such as Fig. 1 institute
Showing, this device includes the extraction kettle 1 equipped with inner core 2, is provided with original gas outlet 4 on extraction kettle 1, fills on original gas outlet 4
There is relief valve 5, during making, make a newly-increased gas outlet 7 at extraction kettle 1 upper position, preferably extraction kettle 1 upper bit is installed
The position height that the position height of the newly-increased gas outlet 7 put is arranged to the original gas outlet 4 with extraction kettle 1 is identical；Then newly
Increase and a balance pipe 8 is set between gas outlet 7 and the air inlet 3 of extraction kettle 1, and in the company of balance pipe 8 with newly-increased gas outlet 7
Meet place and one balanced valve 9 is installed, the port of export of the intake valve 6 of extraction kettle 1 is connected with air inlet 3 and balance pipe 8 simultaneously；In order to
Make balance pressure result more preferable, a sealing ring 10 is installed between the top of inner core 2 and extraction kettle 1.
Embodiment
This is such as shown in Fig. 1, on the basis of existing, increases a newly-increased gas outlet 7 on extraction kettle 1, and in extraction
Still increases a balance pipe 8 between importing and exporting.The main cause causing extraction kettle inner core to deform is that the inlet outlet pressure differential of extraction kettle is big
Make extraction kettle inner core bear external pressure to cause beyond its pressure-bearing limit, method according to the present example, after adding a balance pipe 8,
Before extraction kettle 1 pressure release, first opening the balanced valve 9 of balance pipe 8, using pungent drugs for dispersion and bitter drugs for purgation pressure valve 5 carries out pressure release the most again, according to " minimum resistance
Power principle ", the CO being full of between inner core 2 cylindrical and extraction kettle 1 inwall2Directly entered by balance pipe 8 and bring out on extraction kettle 1
Mouth rather than the solid material in inner core 2, thus ensure that extraction kettle 1 imports and exports direct pressure balance, inner core 2 is subject to
The least not even by External Force Acting, thus ensure that inner core 2 is not damaged.
The method has been applied to the debugging in tens of set supercritical extraction, respond well.The method is not in increasing
In the case of cylinder cost and other a large amount of financial resources, successfully solve the pressure release problem of extraction kettle, bring to manufacturing firm and user
Facility.
