A method for the safety emission of high temperature flue gas of the offshore platform, which includes the high temperature flue gas of the combustion facility (I) through the high temperature flue gas exhaust pipe (1.1) of the combustion facility (I) into the cooling and purifying device body (2.1), and inject the sea water into the cooling and purifying device body (2.1), so that the injected seawater is passed through the cooling and purifying device body (2.1). The water distributor (2.4) above the water distributor (2.4) is sprinkled with cloth washing water, so that the high temperature flue gas is washed from the high temperature flue gas inlet (2.7) below the body (2.1) of the cooling and purifying device (2.1) into the water distributor (2.4) and is washed by the sprinkled seawater to be a cooling and purifying flue gas, and the temperature and purification flue gas is used to remove the liquid drop through the water distributor (2.4) and the drop. The mist eliminator (2.9) is finally discharged to the atmosphere from the cooling and purifying exhaust vent (2.10) at the top of the cooling and purification device (2.1), and the seawater after the high temperature flue gas is washed through the liquid accumulation pool (2.6) in the lower part of the cooling and purification unit (2.1) and discharged into the sea. A cooling and purifying device is also disclosed.
