Detailed Description
The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The endpoints of the ranges and any values disclosed herein are not limited to the precise range or value, and such ranges or values should be understood to encompass values close to those ranges or values. For ranges of values, between the endpoints of each of the ranges and the individual points, and between the individual points may be combined with each other to give one or more new ranges of values, and these ranges of values should be considered as specifically disclosed herein. In this context, when comparing the inner diameters of the orifices or of the ends of a single orifice, it is to be understood that the two are coaxial or substantially coaxial, and further, when the inner diameter of one of the compared orifices is non-uniform, the smallest inner diameter of that orifice is taken as the inner diameter of that orifice.
The invention provides an automatic sampling system capable of preventing water vapor from being condensed, which comprises a sampling head, a computer 4, a flow limiting valve 5, a plurality of groups of electromagnetic valves 6 and sampling tanks 7 which are connected in parallel, wherein the sampling head comprises a T-shaped pipe 1, the end parts of transverse pipe orifices and radial pipe orifices on two sides in the T-shaped pipe 1 are both in an open structure, the inner diameter of the pipe orifice on one side in the transverse pipe orifices is smaller than that of the pipe orifice on the other side, a protrusion 3 is arranged at the position close to the radial pipe orifice in the pipe orifice on the other side, the radial pipe orifices and the flow limiting valve 5 of the sampling head are respectively and sequentially connected with the electromagnetic valves 6 of each group, and the flow limiting valve 5 and the electromagnetic valves 6 of each group are connected with the computer 4.
As shown in fig. 2, the ends of the lateral pipe orifices and the radial pipe orifices on two sides in the T-shaped pipe 1 are both open structures, so that air can enter or be discharged from three ends of the T-shaped pipe, the lateral pipe orifices on two sides of the T-shaped pipe 1 refer to two opposite pipe orifices at the upper end of the T-shaped pipe, and the radial pipe orifices of the T-shaped pipe 1 refer to another pipe orifice perpendicular to the lateral pipe orifices on two sides in the T-shaped pipe 1. When the aircraft flies, air enters the sampling head from the pipe orifice on one side of the T-shaped pipe 1, when the air reaches the upper part of the radial pipe orifice of the T-shaped pipe 1, a suction device (such as a pump) is connected to the end part of the radial pipe orifice of the T-shaped pipe 1, due to the suction effect, part of the air reaching the upper part of the radial pipe orifice is led out from the radial pipe orifice of the T-shaped pipe 1, so that subsequent detection is carried out, the rest of the air rushes through the radial pipe orifice and flows out from the pipe orifice on the other side, and a large amount of water vapor can be condensed. The inner diameter of the pipe orifice on one side in the transverse pipe orifices is smaller than that of the pipe orifice on the other side, namely the upper surface of the lower end of the pipe orifice on one side is higher than that of the lower end of the pipe orifice on the other side, so that the air flow can further rush to the position, far away from the radial pipe orifice, in the pipe orifice on the other side, and the condensed water vapor is not easy to fall into the radial pipe orifice. Meanwhile, a protrusion 3 is arranged in the other side pipe orifice and close to the radial pipe orifice, and the protrusion 3 can prevent water vapor in the other side pipe orifice from flowing into the radial pipe orifice. The radial pipe orifice and the flow limiting valve 5 of the sampling head are respectively connected with the electromagnetic valves 6 of each group in sequence, namely the radial pipe orifice and the flow limiting valve 5 of the sampling head are arranged on a main pipeline and can control the flow on the main pipeline (namely, the total flow of sampling samples is collected), the electromagnetic valves 6 and the sampling tanks 7 which are connected are arranged on each branch pipeline, and the electromagnetic valves can control the flow on each branch pipeline (namely, the flow entering each sampling tank); the flow limiting valve 5 and each group of electromagnetic valves 6 are connected with the computer 4, so that the start and stop of the flow limiting valve 5 and each group of electromagnetic valves 6 can be controlled by using the computer 4, the start and stop time can be automatically recorded, and the sampling duration and the sample amount can be ensured.
According to the present invention, the inner diameter of each end of each pipe orifice is not particularly limited, and the above object of the present invention can be achieved.
Preferably, the inner diameter of the one-side nozzle near the inner end of the tube is smaller than the inner diameter near the outer end of the tube. This increases the flow rate of the gas stream at the end of the tube adjacent the one-sided nozzle, thereby allowing condensation of water vapor to accumulate at the tube end.
Preferably, the inner diameter of the other side nozzle near the inner end of the tube is smaller than the inner diameter near the outer end of the tube. Therefore, the water vapor condensed at the pipe orifice at the other side close to the inner end of the pipe can flow out of the other side pipe orifice along the slope along the direction of the outer end of the pipe orifice.
In a preferred embodiment of the invention, the sampling head further comprises an air inlet nozzle 2, wherein the air inlet nozzle 2 is fixed at the inner end of the tube of the side tube opening. This allows moisture to more easily pass over the radial nozzles without accumulating at the interface of the nozzles and even entering the radial nozzles.
Preferably, the position of the end of the air inlet nozzle 2 far away from the inner end of the pipe exceeds the vertical position of the radial nozzle of the T-shaped pipe 1.
More preferably, the inner diameter of the nozzle 2 near the inner end of the tube is larger than the inner diameter far from the inner end of the tube. That is, the inner diameter of the outlet of the air inlet nozzle 2 is smaller, so that the flow rate of the air flow at the outlet of the air inlet nozzle 2 is improved, and meanwhile, part of water vapor can directly flow back to the outer end due to the gradient and cannot fall down from the outlet of the air inlet nozzle 2, so that the sampling efficiency and quality are further improved.
According to the present invention, the number of sets of the solenoid valves 6 and the sampling tanks 7 is not particularly limited, but it is preferable that the automated sampling apparatus includes 1 to 5 sets of the solenoid valves 6 and the sampling tanks 7 connected in consideration of the efficiency and convenience of the apparatus. Wherein, each group of solenoid valves 6 and sampling tanks 7 can respectively and independently realize the collection and storage of the sampling gas.
According to the invention, the device can also measure the pressure in the pipe, and preferably, the flow limiting valve 5 is provided with a pressure sensor 8.
According to the present invention, the kind of the sampling tank 7 is not particularly limited as long as it can store a sample to be collected, and may be various conventional sampling tanks. Preferably, the sampling tank 7 is a suma tank. The suma tank is an air sampling tank particularly suitable for collecting and storing VOC gas (volatile organic compounds).
According to a preferred embodiment of the present invention, as shown in fig. 3 and 4, the present invention provides an automatic sampling system capable of preventing condensation of moisture, the automatic sampling system capable of preventing condensation of moisture includes a sampling head, a computer 4, a flow limiting valve 5, three groups of electromagnetic valves 6 and a sampling tank 7 connected in parallel, the sampling head includes a T-shaped pipe 1, wherein end portions of two lateral pipe orifices and a radial pipe orifice in the T-shaped pipe 1 are both in an open structure, an inner diameter of one side pipe orifice in the lateral pipe orifices is smaller than an inner diameter of the other side pipe orifice, a protrusion 3 is disposed at a position close to the radial pipe orifice in the other side pipe orifice, the radial pipe orifice and the flow limiting valve 5 of the sampling head are sequentially connected to each group of electromagnetic valves 6, and the flow limiting valve 5 and each group of electromagnetic valves 6 are connected to the computer 4. The inner diameter of the pipe orifice at one side close to the inner end of the pipe is smaller than the inner diameter of the pipe orifice at one side close to the outer end of the pipe; the inner diameter of the pipe orifice at the other side close to the inner end of the pipe is smaller than the inner diameter of the pipe orifice at the other side close to the outer end of the pipe; the sampling head further comprises an air inlet nozzle 2, wherein the air inlet nozzle 2 is fixed at the inner end of the tube orifice on one side; the position of one end of the air inlet nozzle 2, which is far away from the inner end of the pipe, exceeds the vertical position of a radial pipe orifice of the T-shaped pipe 1; the inner diameter of the air inlet nozzle 2 close to the inner end of the pipe is larger than the inner diameter far away from the inner end of the pipe; the flow limiting valve 5 is provided with a pressure sensor 8; the sampling tank 7 is a suma tank. Further, the arrow direction in fig. 3 indicates the direction of the airflow flow; in fig. 4, a dashed box indicates a sampling head (a specific structure is shown in fig. 3), the left side of a dashed line indicates outside of the nacelle, and the right side of the dashed line indicates inside of the nacelle; the bold lines represent devices or lines and the thin lines represent reference designators.
As can be seen from fig. 3, since the extension of the nozzle 2 in the direction of the air flow exceeds the radial orifice, the air flow already exceeds the radial orifice when flowing out of the nozzle 2, so that the air flow does not enter directly into the radial orifice, thereby avoiding the condensation of water vapor in the radial orifice.
In addition, the invention also provides the application of the automatic sampling system capable of preventing the condensation of the water vapor in the collection of the air outside the aircraft cabin.
In the practical use process, the sampling head of the automatic sampling system capable of preventing the condensation of the water vapor is arranged at any position outside the aircraft cabin and is connected with the rest parts arranged in the aircraft through the radial pipe orifice of the sampling head in the connection mode, preferably, the direction of the air inlet is consistent with that of the aircraft head, so that the air can enter the air inlet more conveniently.
