The invention discloses a gas recovery system and a gas recovery method. The gas recovery system is used for recovering gas of gas utilization equipment and comprises a high-pressure tank, a low-pressure tank and a purification bypass, wherein the high-pressure tank is connected with the gas utilization equipment; the low-pressure tank is connected with the gas utilization equipment and connectedwith the high-pressure tank through supercharging equipment; the purification bypass comprises a first controller, a first control valve and a purification device, the first controller is used for controlling the opening and closing time of the first control valve, the high-pressure tank is connected with the input end of the purification device through the first control valve, and the output endof the purification device is connected with the low-pressure tank. The purification bypass arranged between the high-pressure tank and the low-pressure tank is adopted to purify gas output by a high-pressure pipe, the gas produced through purification is supercharged by the low-pressure tank and then conveyed to the high-pressure tank, cyclic utilization of the gas is realized, and the problem ofgas waste is solved.
Description
technical field [0001] The invention relates to the field of gas recovery, in particular to a gas recovery system and a gas recovery method. Background technique [0002] When testing a sealed pipeline, usually a high-purity special gas, such as helium, is injected into the pipeline to detect whether there is any leakage in the pipeline. During the detection process, the concentration of the gas passing into the sealed pipeline will gradually decrease. When the concentration is low to a certain range, the detection gas will be discharged. Fill in the detection gas. Since the detection gas is usually a high-purity special gas, its processing and preparation costs are high, and the discharge of the detection gas will cause waste of gas and increase the cost of pipeline detection. Contents of the invention [0003] The main purpose of the present invention is to provide a gas recovery system and a gas recovery method, aiming at improving the gas waste problem caused by the ...
