NOVELTY - The utility model claims a high temperature flue gas direct purification pressurizing system, the high temperature flue gas direct purification pressurizing system comprises: graphene floating film purifier; the graphene floating film purifier is provided with a low pressure high temperature flue gas inlet and a low pressure high temperature purified gas outlet; a high temperature flue gas supercharger, the high temperature flue gas supercharger is provided with a low pressure high temperature purified gas inlet and a high pressure high temperature purified gas outlet; and a low pressure high temperature gas pipe; one end of the low pressure high temperature gas pipe is connected with the low pressure high temperature purified gas outlet; the other end is connected with the low pressure high temperature purified gas inlet. The utility model can directly recycle the high temperature flue gas discharged from the oil-gas field, purifying, pressurizing, conveying, using, buried in the coal layer, combustible ice layer, thick oil layer oil-gas field, not only effectively increasing production and extracting oil gas, but also permanently burying harmful gas such as carbon dioxide, sulphur dioxide, nitrogen oxide, realizing reducing the synergistic effect; saving energy and reducing emission, harmful to profit, changing waste into valuable.
