Embodiment
A kind of gas-liquid sampling apparatus 2 that the utility model embodiment provides as shown in Figure 2, be connected with the gas outlet 11 of main gas pipe line 1 by sampling branch road 3, comprise: be arranged on 11 places, gas outlet for control main valve 21, the sampling body 241 that the gas of main gas pipe line 1 discharges from gas outlet 11 or stop by opening and closing, on this sampling body 241, be provided with gas sampling mouth 22 for gathering gas and the liquid sample mouth 26 of collection liquid.
The cavity body structure that sampling body 241 is hollow, material is rigid material, as stainless steel, aluminium alloy etc.This sampling body 241 is set to be convenient to condensation and to collect the condensed fluid after the water vapor condensation carrying in high temperature gas flow, this sampling body 241 is connected with sampling branch road 3, and after being arranged on main valve 11, gas sampling mouth 22 and liquid sample mouth 26 are separately positioned on sampling body 241, and the setting position of gas sampling mouth 22 on sampling body 241 be the setting position on sampling body 241 higher than liquid sample mouth 26, thereby can make water vapor rapidly condensation and be finally pooled to sampling body 241 bottom, and air accumulation is on sampling body 241 tops, make the gas that collects purer.
For the collection of the gas sample of being more convenient for, increase collection capacity and the collecting efficiency of gas, gas sampling mouth 22 can be arranged on to middle and upper part or the tip position of sampling body 241, be preferably gas sampling mouth 22 is arranged on the perisporium on sampling body 241 tops obliquely; In like manner for the collection of the liquid sample of being more convenient for, the collection capacity of increase liquid and collecting efficiency can be arranged on liquid sample mouth 26 bottom or the bottom position of sampling body 241, are preferably the bottom position that liquid sample mouth 26 is arranged on vertically downward to sampling body 241.
When the gas passing through in main gas pipe line 1 is high temperature gas flow, gather gas and liquid sample simultaneously, high temperature gas flow passes through from main gas pipe line 1, enter into gas outlet 11, gas enter into sampling body 241 from connecting line, gas in high temperature gas flow discharges from gas sampling mouth 22, further enters in the equipment of collecting gas; And the water vapor carrying in high temperature gas flow enters into sampling body 241, because the space of sampling body 241 is larger, water vapor can rapid condensation become condensed fluid, and is fallen by Action of Gravity Field, thereby discharge from liquid sample mouth 26, further enter in the equipment of collecting liquid.
Further, at gas sampling mouth, 22 places are provided with gas vent operation valve 23, at liquid sample mouth, 26 places are provided with liquid outlet operation valve 25, for controlling the opening and closing of this gas sampling mouth 22 and liquid sample mouth 26, and can carry out separately gas sample collection or carry out separately liquid sample collection, also can gather gas sample and liquid sample simultaneously, and in low temperature environment, open the main valve 21 of gas outlet 11, and by gas vent by-pass valve control 23 and liquid outlet by-pass valve control 25 Close Alls, thereby make high temperature gas flow or condensed fluid be full of whole sampling body 241, thereby prevent from easily occurring icing problem at low temperature condition down-sampling mouth.
And sampling body 241 is not limited to the structure shown in Fig. 2, it can also be various structures, sample body 242 as shown in Figure 3 for hollow circuit cylinder body structure, ellipsoid structure and cylindrical structure be because large with the contact area of high temperature gas flow, thereby can accelerate water vapor in high temperature gas flow and become the speed of condensed fluid; Sampling body 243 shown in Fig. 4 is inverted cone structure, and inverted cone structure is more conducive to the gathering of condensed fluid, facilitates the collection of liquid.
Sampling body 244 shown in Fig. 5 is coil arrangement, and two ports of the pipeline of this coil arrangement are connected with gas outlet 11 and the air intake opening 12 of main gas pipe line respectively, and are provided with gas vent operation valve 21 at 11 places, gas outlet.High temperature gas flow in main gas pipe line 1 can enter into sampling body 244 by the gas outlet 11 of bottom, and can enter into main gas pipe line 1 from the air intake opening on top 12, complete the circulation of gas in sampling body 244, so that the maximum condensing rate of accelerating water vapor of the contact area of the water vapor carrying in high temperature gas flow in the process that high temperature gas flow upwards circulates in sampling body 244 and coil pipe improves the efficiency of collecting liquid; And final remaining gas upwards circulates and discharges by the gas sampling mouth 22 on sampling body 244 tops, thereby high temperature gas flow can be filtered in sampling body 244 in the process of cocycle, obtain purer gas sample, the serviceable life of the air bag using while increasing sampling.
In low temperature environment, can more effectively prevent that at the device shown in Fig. 5 thief hatch from freezing in low temperature environment, open after gas vent by-pass valve control 21, high temperature gas flow enters into sampling body 244 and enters main gas pipe line 1 from the air intake opening 12 on main gas pipe line 1 top from the gas outlet 11 of main gas pipe line 1 bottom, can make like this high temperature gas flow continue to flow in sampling body 244, freeze and stop up in low temperature environment thereby solved gas sampling mouth 22 and liquid sample mouth 26, thus the problem of making troubles to collecting sample.
Certainly, sampling body can also be other irregular hollow cavity structures, does not also affect the beneficial effect of this patent.
In the time of needs gas production body and liquid sample: Fig. 2 to 5 describes as an example of Fig. 2 example, open successively main valve 11, gas vent operation valve 23, and liquid outlet operation valve 25, high temperature gas flow in main gas pipe line 1 is after gas outlet 11 enters into sampling body 241, gas content will is on top, gas sampling mouth 22 by sampling body 241 tops is discharged, and enters into the equipment of collecting gas; And the water vapor carrying in high temperature gas flow rapid condensation in sampling body 241 becomes condensed fluid, because being pooled to liquid sample mouth 26 places, Action of Gravity Field discharges, enter into liquid collection equipment.Gather complete main valve 11, gas vent operation valve 23 and the liquid outlet operation valve 25 of closing successively.Certainly, also can open respectively gas vent operation valve 23 or liquid outlet operation valve 25, carry out respectively the collection of gas sample and liquid sample.
In sum, the gas-liquid sampling apparatus of the utility model embodiment is by the sampling body of the cavity body structure of employing hollow, make in the time that gas and liquid are carried out to collecting sample, the air accumulation of high temperature gas flow that enters into sampling body inside from main gas pipe line, on the top of sampling body, and is discharged from gas sampling mouth; The water vapor carrying in high temperature gas flow can sampling body in rapidly condensation become condensed fluid, be pooled to sampling body middle and lower part get rid of discharge from liquid sample mouth.
Thereby solve while gathering at the same time gas sample and liquid sample, because water vapour entrained in high temperature gas flow can get off in very fast condensation, affect the problem of the collection capacity of gas sample, and increase the serviceable life of sampling air bag used; And solve in the time of collection liquid sample, water vapour condensation is slower, the problem holding of the gases affect condensed fluid simultaneously pouring out; And make to sample and be full of high temperature gas flow in body or condensed fluid is incubated sampling body by outlet by-pass valve control is set, thereby solve the problem that thief hatch easily freezes and stops up in low temperature environment.
