Embodiment
Through instantiation the present invention is further set forth below, should be noted that following explanation only is in order to explain the present invention, its content not to be limited.
Present embodiment comprises a kind of liquid chlorine gasification process; Comprise liquid chlorine storage tank fill process, liquid chlorine vaporizing process and waste gas treatment process; Said liquid chlorine vaporizing process is: the heating medium of the heating agent that is used for liquid chlorine vaporization for not reacting with chlorine; This heating medium is used steam heating earlier, and the heating medium after the heating carries out cycle heat exchange with liquid chlorine again, reaches the purpose of liquid chlorine vaporization; The said heating medium that does not react with chlorine is synthetic conduction oil or chlorinated hydrocabon.
The said steam that is used to heat is the steam of 0.3MPa.
In the process to the heating medium heating, elder generation sets heating medium temperature (between 80-90 ℃), and the temperature signal that utilizes collection is then controlled the temperature realization automatically control of the aperture of heating steam pneumatic control valve to heating medium automatically.
Carry out at heating medium carrying out pump circulation through pump on the pipeline of cycle heat exchange of liquid chlorine vaporization.
Present embodiment also comprises a kind of liquid chlorine carburetion system, and it comprises liquid chlorine gasifier capable and heating medium heater 2, and said heating medium heater 2 is a tubular heat exchanger.Said heating medium heater 2 connects said chlorine liquid carburetor 1 through pipeline; Circulation has not the heating medium that reacts with chlorine in heating medium heater 2 and the chlorine liquid carburetor 1; Said heating medium heater 2 is that heating medium storage tank 8 links to each other with the vapor recycle device; The steam that is used to heat in the said vapor recycle device is the steam of 0.3MPa, and heating medium sends into that the heating liquid chlorine makes its vaporization between chlorine liquid carburetor 1 pipe after with the 0.3MPa steam heating." heating medium that does not react with chlorine " is chlorinated hydrocabon.On the pipeline between heating medium heater 2 and the chlorine liquid carburetor 1, be provided with forced circulation pump 7.
