Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example the dehumidification system of the pressure vessel of the present invention is further elaborated.Should be appreciated that this place
The specific embodiment described, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, the dehumidification system of a kind of pressure vessel, for pressure vessel 1 is dehumidified, bag
Include: nitrogen injection device 2, vacuum extractor 3, air inlet pipe 4 and escape pipe 5；Nitrogen injection device 2 leads to
Cross air inlet pipe 4 to connect with pressure vessel 1, for pressure vessel 1 nitrogen injection；Vacuum extractor 3 leads to
Cross escape pipe 5 to connect with pressure vessel 1, for being extracted out by the gas in pressure vessel 1.
Work process is: when finding to have water in pressure vessel 1, be connected among system by pressure vessel 1,
By nitrogen injection device 2 by nitrogen injection pressure container 1, make nitrogen pressure in pressure vessel 1
Reach 0.3MPa.So can be by nitrogen by the gas (including oxygen and harmful gas) in pressure vessel 1
Discharge, increase system pressure simultaneously, prevent the water corrosion to pressure vessel 1 and the formation of anvil cinder.
Then starting vacuum extractor 3, the gas in pressure vessel 1 is extracted out by vacuum extractor 3.True when taking out
Empty device 3 cannot be time vacuum (about 200Pa) no longer changes in gas bleeding or pressure vessel 1, will pressure
The vacuum of force container 1 keeps 2 hours, if within vacuum returns to 100Pa, then may determine that pressure
Aqueous water in container 1 and vaporous water clearance rate, more than 99%, reach the requirement except water.Due in low pressure
(1360Pa) under the conditions of, the boiling point of water is about 11.7 DEG C, therefore when vacuum extractor 3 is by pressure vessel
Gas in 1 is extracted out, and when reaching low-pressure state, room temperature 20 DEG C disclosure satisfy that the explosive evaporation requirement of water,
As long as at this moment there being water, all can be evacuated device 3 with the state of steam and extracting out.Vacuum level requirements is improved
To 200Pa, steam now is 0.565m than pressure3/ g (space of i.e. 1 cubic metre water Han 1.77g),
And space water Han 20g of lower 1 cubic metre of room temperature, and water content now is relevant with humidity at that time.
As a kind of embodiment, nitrogen injection device 2 includes nitrogen pot 6 and device for drying and filtering 7, nitrogen
Tank 6 is connected with air inlet pipe 4 by device for drying and filtering 7, and the nitrogen drying filter 7 in nitrogen pot 6 enters
It is injected in pressure vessel 1 by air inlet pipe 4 again after row dry filter.So nitrogen is through device for drying and filtering 7
Be injected in pressure vessel 1 by air inlet pipe 4 after being dried filtration, it is possible to avoid the occurrence of moisture or other
Impurity enters in pressure vessel 1 in company with nitrogen, not only increases dehumidification rate, can more efficiently prevent again
Stop corrosion and the formation of anvil cinder of pressure vessel 1.
As a kind of embodiment, air inlet pipe 4 arranges the first stop valve 8, is so possible to prevent pressure to hold
Steam in device 1 drives in the wrong direction and enters device for drying and filtering 7 by air inlet pipe 4, thus alleviates device for drying and filtering 7
Unnecessary load, extends the use cycle of device for drying and filtering 7.
As a kind of embodiment, the second stop valve 9 is set between device for drying and filtering 7 and nitrogen pot 6, this
Sample can be avoided the steam in device for drying and filtering 7 to drive in the wrong direction and enter nitrogen pot 6, thus ensure that in nitrogen pot 6
The quality of nitrogen.
As a kind of embodiment, vacuum extractor 3 includes: vacuum pump 10 and catch cooler 11, vacuum pump
10 connect with escape pipe 5 by catching cooler 11, and vacuum pump 10 passes through escape pipe 5 by pressure vessel 1
Gas is extracted out, catches cooler 11 and dehumidifies for the gas extracting vacuum pump 10 out.
Catch and cooler 11 can contain solid dry ice, but be not limited to this, the water that solid dry ice can will be extracted out
Steam is discharged after directly solidifying and is caught cooler 11, makes the steam in gas be eliminated.The gas elder generation warp being drawn out of
Cross and enter back into vacuum pump 10 after catching cooler 11 dehumidifying, it is possible to prevent steam from entering vacuum pump 10, thus ensure
The efficiency of vacuum pump 10 and performance.
As a kind of embodiment, escape pipe 5 arranges unidirectional stop valve 12, when vacuum pump 10 cannot be taken out
Go out vacuum (about 200Pa) in gas or pressure vessel 1 when no longer changing, check valve can be closed, will pressure
Force container 1 carries out pressurize, it is not necessary to keep the vacuum of pressure vessel 1, joint by running vacuum pump 10
The about energy, and alleviate the load of vacuum pump 10, extend the service life of vacuum pump 10.
As a kind of embodiment, also including weighing device 13, weighing device 13 is connected with catching cooler 11,
And weigh to catching cooler 11.
Catching after steam solidifies by solid dry ice in cooler 11, the weight catching cooler 11 can produce change,
According to catching the design requirement of cooler 11, when the weight catching cooler 11 increases to a certain degree, by condense
Solid ice cleans out, and will catch cooler 11 and soak such as rapid condensation in condensed water, is then carrying out evacuation dehumidifying.
As a kind of embodiment, also include Pressure gauge and vacuum meter, Pressure gauge (not shown) and vacuum
Table (not shown) is arranged on pressure vessel 1, for the pressure of gas in pressure vessel 1 and vacuum
Degree shows.
The dehumidification system of the pressure vessel of the embodiment of the present invention, reasonable in design, simple in construction, dehumidification rate height,
And it is prevented from pressure vessel internal corrosion.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
