The characteristics of structure is simple, easy to operate, high degree of automation.
Description of the drawings
Fig. 1 is the structure diagram of the embodiment of the present invention.
Specific embodiment
In the following, with reference to specific embodiment, the present invention is described further.
As shown in Figure 1, the continuous abjection of the dissolved gas of the present embodiment and collection device include hollow cylinder 1, sample
Cabin 2, piston portion 3, gas abjection check valve 4, gas collection check valve 5, gas production bag 6, gas flowmeter 7 and supersonic generator
8.At least one end of cylinder 1 is closing.
Sample chamber 2 is set in cylinder 1, and sample chamber 2 is closed vacuum cavity.Piston portion 3 is set in cylinder 1, sample
The top in product cabin 2, the outer diameter of piston portion 3 and the internal diameter of cylinder 1 are adapted.The outer diameter of piston portion of the present invention and cylinder
Internal diameter refers respectively to the external dimensions of piston portion and the inside dimension of cylinder, and when cylinder 1 is cylinder, piston portion 3 also mutually should be
Circle, the outer diameter of piston portion just refer to circular outer diameter, and the internal diameter of cylinder just refers to the internal diameter of cylinder, when cylinder for square tube or
During other polygon cylinders, piston portion also mutually should be rectangular or other polygons, and the outer diameter of piston portion just refers to that rectangular or other are more
The external dimensions of side shape, the internal diameter of cylinder just refer to the shape of inside dimension, i.e. piston portion 3 that square tube or other polygons lead to
It is identical with the shapes and sizes inside cylinder 1 with size.Piston portion 3 can be moved back and forth up and down along the axis direction of cylinder 1, piston
Motor or cylinder or Driven by Hydraulic Cylinder can be used in portion 3.
Gas deviates from check valve 4 and gas collection check valve 5 is set on the roof of sample chamber 2, wherein, gas abjection is single
It is set in connection sample chamber 2 and cylinder 1 between 2 roof of sample chamber and piston portion 3 in the channel in space to valve 4, gas collection
Check valve 5 is set in connection cylinder 1 between 2 roof of sample chamber and piston portion 3 in the channel of space and flowline 9, gas production
Another termination gas production bag 6 of pipeline 9.Gas flowmeter 7 is set on flowline 9, can be adopted to flowing through the entrance of flowline 9
The flow of the gas of airbag 6 is counted.The practical demarcation strip to be set in cylinder 1 of roof of sample chamber 2, demarcation strip is in cylinder
An enclosure space is separated out in body 1 as sample chamber, its complementary space in sample chamber and cylinder is isolated.
Supersonic generator 8 is provided in sample chamber 2, the supersonic generator 8 of the present embodiment is set to sample chamber 2
Bottom, that is, the bottom of cylinder 1.Gas abjection check valve 4 is used to control gas interior to sample chamber 2 and living from sample chamber 2
Space outflow between piston part 3, gas collection check valve 5 are used to control the sky that gas can only be between sample chamber 2 and piston portion 3
Between flowed out into flowline 9.
The operation principle of the gas abjection collection device of the present invention is illustrated below：
Half flowing shape deposit is full of sample chamber 2, piston portion 3 is made to be moved to the roof of sample chamber 2, the bottom of piston portion 3
Face is closely set in the gas abjection check valve 4 of 2 roof of sample chamber and gas collection check valve 5, while gas production bag 6 is taken out very
It is empty；
During work, start supersonic generator 8 first, then piston portion 3 is driven to move upwards, in piston portion 3 from sample
During 2 roof of cabin moves up, one can be formed in the space below 1 inner carrier portion 3 of cylinder between 2 roof of sample chamber
The environment of a negative pressure opens gas abjection check valve 4 at this time, and gas collection check valve 5 is closed, in negative pressure and ultrasound
Under the action of wave, the dissolved gas in half flowing shape deposit in sample chamber 2 will be deviate from, and deviate from check valve 4 through gas
It diffuses in the space of 3 lower section of piston portion；
When piston portion 3 is moved to top, during piston portion 3 moves down, gas abjection check valve 4 is closed, is beaten
Gas collection check valve 5 is opened, piston portion 3 can be by the gas deviate from out of sample chamber 2 through gas collection check valve 5 and flowline
9 are expressed in gas production bag 6, and the gas flowmeter 7 being set on flowline 9 can record the gas volume of abjection；
When piston portion 3 moves down on earth, piston portion 3, which starts again at, to move up, and repeats abovementioned steps, starts next
A degassing and the process of collection；When the reading of gas flowmeter 7 is not further added by, you can think in sample chamber 2 in deposit
Dissolved gas is all deviate from.
Previous embodiment is vertically set with cylinder, and piston region is in the top of sample chamber, above sample bin
It moves back and forth up and down, but cylinder can also be horizontally disposed, when cylinder is horizontal positioned, piston portion can be located at sample chamber
Left or right side, and left and right moves back and forth in the horizontal direction.
Apparatus of the present invention can realize the company of dissolved gas in deposit in sample chamber using the reciprocating motion of piston portion
Continuous abjection and collection work, high degree of automation, the constituent analysis research for subsequent dissolution gas provide basis, can be applied to ocean
Sample collection in the fields such as scientific investigation, ocean water body environmental survey, marine oil and gas investigation and exploitation, before there is wide application
Scape.
For those skilled in the art, technical solution that can be as described above and design are made other each
Kind is corresponding to be changed and deforms, and all these change and deform the protection model that should all belong to the claims in the present invention
Within enclosing.
