Abstract
The utility model discloses a low pressure or negative pressure gas sampler, which comprises a pressure regulator, a sampling pipe, a sample storage bottle and a sample injector, wherein the pressure regulator is connected with the sampling pipe via a connecting pipe; a triple valve and a two-way valve are arranged on the sampling pipe, an inlet end of the sample storage bottle is connected with the triple valve, a two-way valve and a sealing plug are arranged on an outlet end, and the sample injector is inserted and penetrated into the sealing plug. The utility model has the advantages that pressure difference between a gas reactor and outside atmospheric pressure can be equal to the outside atmospheric pressure via regulation; under the condition that an ongoing reaction in the reactor is not influenced, gas collection is realized and the real time analysis and the measurement of gas are realized.
Description
Technical field
The utility model relates to the gas reactor technical field, particularly a kind of novel low pressure or negative-pressure gas sampling thief.
Background technology
At present, the kind of gas reactor is divided into continuously and two kinds of batch (-type)s.So their sampling methods in analysis are also just different.The sample analysis of continous way gas reactor is with regulator and the surveying instrument (as: gas chromatography of sample tap by a six-way valve; Chromatograph mass spectrometer etc.) on-line analysis is carried out in connection.And the sampling and measuring of batch (-type) gas reactor usually is to stop the back sampling in reaction.Under at condition of negative pressure, still needing adds inert gas so that acquisition could sampling and measuring with the state of external atmosphere pressure balance.Can bring problems like this: know from experience to analysis result as the adding indifferent gas and bring certain error, if the negative pressure in the reactor is big more, the inert gas of adding is just many, and analytical error is also big more.Simultaneously, adding inert gas may introduce impurity and change the reliability reduction that reactiveness makes the response analysis result.
Summary of the invention
The purpose of this utility model is a kind of novel low pressure or the negative-pressure gas sampling thief that designs at the deficiencies in the prior art, it is applicable to the serial sampling of batch (-type) gas reactor, need not add inert gas, need not stop reaction, reaction system is not had influence, overcome the shortcoming of traditional sampling method.
The concrete technical scheme that realizes the utility model purpose is: a kind of low pressure or negative-pressure gas sampling thief, it is characterized in that it comprises pressure governor, sampling pipe, sample storage bottle, injector, and pressure governor is connected by connecting pipe with sampling pipe; Sampling pipe is provided with T-valve and two-way valve, and the sample storage bottle entrance point connects T-valve, and endpiece is provided with two-way valve and sealing-plug, and injector is pegged graft and penetrated sealing-plug.
The utility model can will be adjusted to external atmosphere pressure identical with the pressure differential between outside atmosphere is pressed in the gas reactor; Under the condition that does not influence ongoing reaction in the reactor, realize gas collecting, and gas is realized in good time analysis to measure.
Description of drawings
Accompanying drawing is the utility model structural representation
Embodiment
Consult accompanying drawing, when the utility model uses, only need the sample tap of stopple coupon 6 ports and gas reactor is connected, close two-way valve 1,5, again T-valve 2 is rotated to the state that three connecting pipes communicate.Remove sealing-plug 10, connect the vacuum pump line at port 8 places, open two-way valve 5, open vacuum pump the utility model is vacuumized, after gas drains, close two-way valve 5, pull out the vacuum pump line from port 8 after, install sealing-plug 10 again.
If reactor is a negative pressure state, operate as follows:
Open two-way valve 1, the gas sample in the reactor will enter the utility model (inner is vacuum state), and the piston 9 that spurs to the right then in the pressure governor 3 arrives suitable position, closes two-way valve 1.Decontrol piston 9, piston 9 is moved to the left automatically to reach with outside atmosphere and flattens the weighing apparatus state.At this moment, available injector 11 puncture through seal plugs 10 are opened two-way valve 5 simultaneously and are made the pin on the injector 11 extend in the sample storage bottle 4 sampling and measuring of bleeding.Because the existence of pressure governor 3 is arranged, injector 11 is in bleeding, and the piston 9 on the pressure governor 3 can be moved to the left, and is to carry out under constant voltage all the time thereby make whole sampling process.
If vacuum tightness is bigger in the reactor, follow these steps to carry out:
1, can open two-way valve 1 earlier, the gas sample in the reactor will enter the utility model.
2, the piston 9 that spurs to the right then in the pressure governor 3 arrives suitable position, closes two-way valve 1.Decontrol piston 9, piston 9 can be moved to the left to pressure governor 3 bottoms because of atmospheric effect.
3, again T-valve 2 is rotated to left and right sides connecting leg (the down pipe obstructed) state that communicates.Open two-way valve 1, spur piston 9 to the right, close two-way valve 1 at once, unclamp piston 9 to maximum position.
4, swivel tee valve 2 rotates to three connecting leg communicating states again.The gas sample will enter in the sample storage bottle 4.
5, if can't meet the demands, but repetitive operation 3,4 steps are till meet the demands.
If reactor is low barotropic state, operate as follows:
1, the piston 9 on the hand steered pressure governor 3 is opened two-way valve 1, owing in the reactor certain malleation is arranged, is vacuum state in the utility model simultaneously, and the gas sample can enter the utility model rapidly.
2, hand steered piston 9 makes it arrive suitable position, closes two-way valve 1 at once.Unclamp piston 9 again, the position that it is suitable that piston 9 can move right and reach balance in external pressure.
3, then, with the needle-penetration sealing-plug 10 on the injector 11, open two-way valve 5 simultaneously and make the pin on the injector 11 extend in the sample storage bottle 4 sampling and measuring of bleeding.
