[0030] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the drawings, and the present invention will be further elaborated.

[0031] First, in combination with Figure 1 A sampling system for a tank area according to an embodiment of the present invention will be described, which is used for sampling in a sample tank area and has a wide range of application scenarios.

[0032] As Figure 1 shown, a sampling system for a tank area according to an embodiment of the present invention includes a sampling bottle 1, an acquisition module, a circulation module, and a sampling module.

[0033] Specifically, as Figure 1 shown, the sampling bottle 1 is used to store the collected samples.

[0034] Specifically, asFigure 1 As shown, the sampling module is connected to

[0035] the external sample tank area, and is used to collect samples in the sample tank area and input them into the sampling bottle 1. The sampling module includes: at least one sampling tube 21, a pneumatic pump 22, a delivery tube 23, a gas delivery component, at least one first needle valve 25, and a second needle valve 26. One end of at least one sampling tube 21 is connected to the sample tank area; the input end of the pneumatic pump 22 is communicated with the other end of at least one sampling tube 21; one end of the delivery tube 23 is connected to the output end of the pneumatic pump 22, and the other end of the delivery tube 23 is communicated with the sampling bottle 1; the gas delivery component is connected to the pneumatic pump 22 and is used to deliver compressed air into the pneumatic pump 22; the number of first needle valves 25 is equal to the number of sampling tubes 21, and they are in one-to-one correspondence and communicate with each other to control the on-off of the sampling tube 21; the second needle valve 26 is connected to the delivery tube 23 to control the on-off of the delivery tube 23. The number of sampling tubes 21 is multiple, and multi-channel sampling can be performed.

[0036] Furthermore, as Figure 1 shown, the gas delivery component includes: an intake pipe 241, a ball valve 242, and a pressure regulating valve 243. One end of the intake pipe 241 is connected to an external gas source, and the other end of the intake pipe 241 is connected to the pneumatic pump 22; the ball valve 242 is communicated with the intake pipe 241 to control the on-off of the intake pipe 241; the pressure regulating valve 243 is communicated with the intake pipe 241 to control the pressure in the intake pipe 241.

[0037] Furthermore, as Figure 1 shown, the sampling module further includes: a pressure detector 27, and the pressure detector 27 is communicated with the delivery tube 23 and is used to detect pressure.

[0038] Specifically, as Figure 1 shown, the circulation module is connected to the sampling module and is used to circulate part of the samples collected by the sampling module back to the sample tank area. The circulation module includes: a circulation pipe 31, a check valve 32, and a third needle valve 33. One end of the circulation pipe 31 is communicated with the delivery tube 23, and the other end of the circulation pipe 31 is connected to the sample tank area; the check valve 32 is communicated with the circulation pipe 31; the third needle valve 33 is communicated with the circulation pipe 31 to control the on-off of the circulation pipe 31. Through the setting of the circulation pipe 31, part of the samples collected by the sampling module can be circulated back to the sample tank area, ensuring the tightness of the sampling system.

[0039] Specifically, as Figure 1 shown, the sampling module is connected to the sampling bottle 1 and is used to take out the samples in the sampling bottle 1. The sampling module includes: a sampling pipe 41 and an activated carbon adsorption tube 42. One end of the sampling pipe 41 is connected to the sampling bottle 1; the activated carbon adsorption tube 42 is communicated with the sampling pipe 41 and is used for adsorption and filtration.

[0040] Working principle: When in use, power is provided by the pneumatic pump 22. By controlling the on / off of the sampling tube 21, individual sampling or multi-channel sampling can be carried out. The sample is collected into the sampling bottle 1 and finally taken out through the sampling tube 41 and adsorbed by the activated carbon adsorption tube 42.

[0041] As described above, with reference to Figure 1 A tank area sampling system according to an embodiment of the present invention has been described. The sampling in the process irrigation area is controlled by each sampling needle valve, which is convenient and fast. It can perform individual sampling or multi-channel sampling. The pneumatic pump 22 can provide power, which is both environmentally friendly and energy-saving.
