Cold and dry method integrated sampling equipment and working method thereof

The invention belongs to the technical field of detection and sampling, and relates to cold and dry method integrated sampling equipment and a working method thereof. The invention includes a sampling pump for pumping gas through a sampling inlet line and a sampling filter into a multi-channel cooling tube. An inlet of the sampling pump is connected with a sampling inlet pipeline through a sampling filter, an outlet of the sampling pump is connected with a sampling outlet pipeline through a multi-channel cooling pipe, gas is input into the sampling filter through the sampling inlet pipeline, the sampling filter is used for filtering impurity particles and water vapor in the gas, and the influence of the impurity particles and the water vapor on the device is reduced. The multi-channel cooling pipe is a main cooling place for sampling gas, and the sampling outlet pipeline is used for discharging the sampling gas, so that the sampling gas is convenient to collect. And the condensing device is used for cooling g
