Liquid chlorine is one of the commonly used raw materials in chemical production, and the safety of the liquid chlorine needs to be particularly noticed in the processes of transportation, use and storage due to the extremely toxic characteristic of the liquid chlorine. The common methods for unloading the liquid chlorine tank truck are high-level unloading and air or nitrogen pressurized unloading. The liquid chlorine delivery pump used in the high-level unloading is very easy to damage and generate cavitation and other reasons, so that the high-level unloading is not widely used by industrial enterprises. The more common methods of air or nitrogen pressurized unloading also have significant disadvantages: the pressure of the liquid chlorine storage tank is maintained at 1.0-1.2 MPa after each unloading of the liquid chlorine tank car, and at such a high pressure, when the liquid chlorine of the train or the automobile tank car is to be received again or supplied to the production line, the pressure of the liquid chlorine storage tank must be reduced to below 0.5 MPa. In the pressure reduction process, a large amount of chlorine, air or nitrogen is discharged, and the safety can be ensured only by destroying the chlorine, the air or the nitrogen through an alkali neutralization process, so that the environment is not influenced, and a large amount of liquid chlorine and alkali are consumed. Particularly, in summer, when the temperature of the liquid chlorine reaches 20 ℃, the saturated vapor pressure of the liquid chlorine is 0.68MPa, and if the pressure of the liquid chlorine storage tank is reduced to 0.5MPa, a large amount of chlorine gas must be evaporated.
