Gas carrier band type trace water long-range conveying-collecting device and method

The invention discloses a gas carrier band type trace water long-range conveying-collecting device and method, and aims to solve the problems that an existing water conveying and collecting method cannot be applied to trace water, and the trace water is easily attached or adsorbed on the surface of a pipeline, so that a water sample is difficult to obtain or extremely few water samples are obtained. The device specifically comprises a trace water container, a water carrying pipeline, a gas return pipeline, a water collecting unit, a diaphragm pump, a dry carrier gas unit and a shunting pipeline, two ends of the water carrying pipeline are respectively communicated with the trace water container and the water collecting unit, and the water carrying pipeline is provided with a first valve, an exhaust port, a fifth valve and a dry carrier gas unit; the drying carrier gas unit comprises a drying pipeline communicated with the carrier water pipeline, a high-pressure gas cylinder arranged on the drying pipeline, a
