Abstract

The utility model relates to a gas-liquid separator which is an apparatus used for separating contained gas from liquid and performing a qualitative and quantitative analysis and can be especially used for gas analysis in water quality monitoring. The utility model comprises a sample injecting plate, a receiving plate and a breathable film, wherein a sample injecting narrow slot is arranged on the sample injecting plate, a narrow slot is arranged on the receiving plate, and the two notches of the two plates are opposite to each other and tightly connected; the breathable film is spaced between the two notches; the sample injecting narrow slot is a deep slot. When water sample flows through the bottom of the sample injecting narrow slot, the contained gas rises up and enters the narrow slot of the receiving plate after passing through the breathable film, and then the kind and the content of the gas can be detected by a specific reagent. Owing to the sufficient depth of the sample injecting narrow slot, the water sample can flow through the bottom of the slot instead of reaching the notch, so that the contact of the water with the breathable film at the notch can be avoided to result in the influence on the service life.

Description

Gas-liquid separator

Technical field

The utility model relates to a kind of gas-liquid separator, is used for the contained gas of separating liquid and carries out the instrument of qualitative and quantitative analysis.

Background technology

In the liquor analysis, need the content of some gas componant in the monitoring solution, therefore need isolate the gas in the solution example.Gas-liquid separator promptly is to be used for the instrument that separates and carry out qualitative and quantitative analysis from sample in the liquor analysis.This gas-liquid separator forms with being carved with equally by being carved with stria sample introduction plate tight linking to each other of stria dash receiver, and four end interfaces of two plate strias are connected with capillary respectively, and two plate notches overlap relatively, isolate with breathable films therebetween.Sample or sample and release liquid mix the back with certain flow rate from capillary during by sample introduction plate stria, contained gas upwards sees through ventilated membrane and enters that to be accepted liquid in the dash receiver stria collected in the liquid stream, thereby realizes the separation of gas-liquid.The shortcoming of this gas-liquid separator is that the stria of sample introduction plate is too shallow, and multiple breathable films in notch always contacts with sample, very easily stops up, and influences service life and test effect.

Summary of the invention

The purpose of this utility model provides a kind of improved gas-liquid separator, and it can prevent contacting of breathable films and sample liquid, prolongs film service life, guarantees to test effect.

This gas-liquid separator comprises the sample introduction plate that has the sample introduction stria, the dash receiver that has stria and breathable films, two board slot mouths relatively and be fastenedly connected, breathable films is located between two plates two notches is isolated, sample introduction plate and dash receiver two ends are connected to the capillary that communicates with stria two ends separately respectively, said sample introduction stria is a deep trouth, the degree of depth of vertical direction that is groove does not contact breathable films at least greater than two times of width of notch to guarantee sample when flowing in groove.

For easy to process, the sample introduction plate can be combined by base plate that has shallow slot and the deep-well plates that has deep hole, and breathable films is between the stria of and dash receiver survey suitable for reading in deep hole.

This gas-liquid separator another program be the stria oral-lateral of stria mouth and dash receiver of said sample introduction plate to relative, the sample introduction plate extends to the deep trouth of vertical direction downwards from the side direction notch.The processing method that this kind opened stria downwards from side direction is also comparatively convenient.

In addition, two air interfaces that communicate with the sample introduction groove also can be established in addition in sample introduction plate two ends, air pump and switchable multiple-way valve by serial connection between the capillary of two interfaces are linked to be the loop, said multiple-way valve can be opened before sample introduction, the sample introduction groove is communicated with outside air, the air that pumps into can purge the sample introduction stria, to remove the residual gas of a last sample, eliminates memory effect.

During this device sample introduction, the mixed liquor of sample or sample and release liquid passes through from the deep trouth bottom, and contained gas discharges and rises in the solution, enter in the receiving slit through ventilated membrane to be collected, thus the separation of realization gas-liquid.

Because the sample introduction stria is darker, sample only passes through at trench bottom, can not avoid the breathable films contact sample of notch, so water permeable membrane not be difficult for stopping up the prolongation in service life completely to the top of groove.Can be used for the gas content analysis of water quality monitoring and other liquid.

Description of drawings

Fig. 1, Fig. 2, Fig. 3 are three example structure schematic diagrames of the utility model gas-liquid separator.

Fig. 1 (1) is the A-A profile of Fig. 1.

Fig. 2 (1) is the B-B profile of Fig. 2.

Fig. 3 (1) is the C-C profile of Fig. 3.

Among each figure: 1-dash receiver, 1-1-stria, 1-2,1-2 ', 2-2,2-2 ', 2-3,2-3 '-capillary, 2-sample introduction plate, 2-1-sample introduction stria, 2-2-sample introduction base plate, 2-3-deep-well plates, 3-4-deep hole, the saturating film of 4-, 5-multiple-way valve, 6-air pump, 7-bolt.

See Fig. 1 and in conjunction with Fig. 1 (1), in the present embodiment, dash receiver 1 is superimposed 2 about with the sample introduction plate, and two plates are continuous by bolted.The dash receiver downside has stria 1-1, and the upside of sample introduction plate 2 has sample introduction stria 2-1, and sample introduction stria 2-1 is a deep trouth, and the notch of two plates is relative up and down, is separated with breathable films 4 between the two.Dash receiver 1 is provided with the interface that communicates with groove 1-1 two ends, and two end interfaces are connected with capillary 1-2,1-2 '; Equally, two end interfaces of sample introduction plate 2 are connected to capillary 2-2 and the 2-2 ' that communicates with sample introduction stria 2-1.Water sample feeds sample introduction stria 2-1 from capillary 2-2, and gas rises in the water, penetrates in the stria 1-1 from ventilated membrane 4, feeds acceptable solution, test gas kind and content by capillary 1-2.Water sample only passes through in the bottom of groove 2-1, can not arrive notch, so film can not contact water sample and stops up.

Fig. 2 and Fig. 2 (1) example is represented, the sample introduction plate is made up of base plate 2-2 and deep-well plates 2-3, folded mutually up and down with dash receiver 1 three, be fastenedly connected, deep-well plates 2-3 has deep hole 3-1, the sample introduction stria 2-1 of it and base plate 2-2 upside is combined into deep trouth, is separated by with breathable films 4 between deep-well plates 2-3 and the dash receiver 1.Other is identical with Fig. 1 example.

Fig. 3 and Fig. 3 (1) expression dash receiver 1 is overlapping with the side with sample introduction plate 2, with 7 fastening linking to each other of bolt, as Fig. 3 (1), the notch of dash receiver 1 and sample introduction plate 2 all is located at the side, sample introduction stria 2-1 is the vertical deep trouth of the downward extension of notch from the side, the notch of the stria 1-1 of dash receiver 1 is relative with the notch of sample introduction stria 2-1, shown in Fig. 3 (1), is separated by with breathable films 4 between two notches.In Fig. 4 example, except that be provided with Fig. 1,2 same capillary 1-2,1-2 ', 2-2,2-2 ', also set up capillary 2-3 and 2-3 ', serial connection air pump 6 and switchable multiple-way valve 5 between this two capillary.Need when the scavenging of sample introduction groove, valve 5 can be transferred to the air inlet position, pump into air to the sample introduction groove, purge by pump 6.Purging finishes, and termination of pumping transfers to close stance with valve 5, treats sample introduction next time.
