However, in the steam use and condensed water delivery processes, the condensed water contains certain organic matters, especially in petrochemical and chemical industries, due to equipment leakage or other reasons, the condensed water generally contains a small amount of oil, more than 90% of the condensed water exists in an emulsified state, so that the condensed water cannot be directly used as boiler make-up water, and the use requirements can be met after purification treatment.
At present, various process routes are available for the fine treatment of condensed water at home and abroad, but the processes for high-temperature working conditions are not many and have various defects. For example, a conventional activated carbon filter mainly removes oil by using its adsorption function, but only adsorbs relatively large oil droplets, but does not remove emulsified oil, and desorbs the oil after saturation to release the adsorbed oil. After the active carbon is saturated, the active carbon can be continuously used or directly replaced by new active carbon after being regenerated, the time and the labor are wasted, a large amount of solid waste can be generated, and simultaneously, when the active carbon operates under the high-temperature working condition, silicon can be separated out and is not easy to remove, and the water quality of condensed water is influenced. Therefore, how to remove organic pollutants such as oil in the condensed water, improve the purification quality of the condensed water and ensure that the water quality at the outlet can meet the requirements is a technical problem to be solved urgently at present.
