The invention provides a liquefied gas safe environment-friendly sampling system and method. The sampling system comprises a liquefied gas tank vehicle, a miniature liquefied gas pump and a sampling device, wherein a liquid phase opening of the liquefied gas tank vehicle is connected with a first inner buckle fast connector; a gas phase opening of the liquefied gas tank vehicle is connected with a second inner buckle fast connector; the first inner buckle fast connector and the second inner buckle fast connector are respectively inserted and connected with an opening and closed fast connector; the opening and closed fast connector is respectively connected in series with the miniature liquefied gas pump and the sampling device through a liquid phase pipeline and the gas phase pipeline. The sampling system has the advantages that the structural design is reasonable; the function of sampling the liquefied gas is realized; in addition, excessive liquefied gas in the whole sampling process cannot be discharged into the air in the whole sampling process; pollution caused on the environment can be avoided; the operation of the whole sampling method is simple and convenient; the popularization and the application are convenient.
Description
technical field [0001] The invention relates to the technical field of chemical industry, in particular to a safe and environment-friendly sampling system and method for liquefied gas. Background technique [0002] The liquefied gas sampling operation in the prior art is as follows: install and fix the sampler on the sampling pipeline, open the exhaust root valve of the sampler, the inlet root valve of the sampler, and the two sampling hand valves at the front and back in sequence, so that the liquefied gas can directly flow into the air. Drain and gas-displace the sampler. When the sampler is fully replaced, then close the sampler exhaust root valve to take a sample. After the sampling is completed, close the sampler intake root valve, the front and rear sampling hand valves in turn, and finally remove the sampler. [0003] The existing liquefied gas sampling methods have the following disadvantages: (1) The discharge of liquefied gas is large, and there is a danger of co...
