Process and system for inhibiting cold fog and saving energy of LNG (Liquefied Natural Gas) vaporizing station

The invention provides a process and system for inhibiting cold fog and saving energy of an LNG (Liquefied Natural Gas) vaporizing station. Vaporizing devices in different forms are arranged and combined into a plurality of vaporizing modes with different energy consumption. When LNG is vaporized for supply, the vaporizing mode with lower energy consumption is preferentially selected, the environment and operation data are monitored through a detection module and fed back to a control module, if the control module judges that cold fog can be generated, the vaporizing mode is switched into the vaporizing mode with higher energy consumption, and meanwhile, the feed water temperature of a water bath-type vaporizer is regulated and controlled through flow and temperature monitoring of an outlet of a natural gas transport pipeline. According to the process and the system, the influence of the cold fog generated in the LNG vaporizing process on the surrounding environment can be avoided, and meanwhile, the energy c
