Abstract

The invention discloses an automatic loading system of leakage-free loading arms of a liquefied chlorine tank truck. The automatic loading system is connected with a liquefied chlorine tank of the tank truck and a liquefied chlorine storage tank of a user to carry out liquefied chlorine loading operation; a liquid phase filling opening and a gas phase pumpback opening are formed in the top of the liquefied chlorine tank of the tank truck; the liquid phase filling opening is communicated with the liquefied chlorine storage tank through a liquid phase leakage-free loading arm of the liquefied chlorine and the gas phase pumpback opening is communicated with a chlorine recycling treatment device through a gas phase leakage-free loading arm of the liquefied chlorine. The automatic loading system is mainly applied when the liquefied chlorine is filled into the tank truck through the leakage-free loading arms; an explosion separation batch controller is used for switching each pneumatic stop valve to realize liquefied chlorine filling and excess pumping back and for measuring the pressures, temperatures and flow rates of liquefied chlorine and gasified chlorine in each pipeline, so that the purpose of automatic metering, quantitative control, safe measuring and interlocking during filling is realized.

Description

technical field [0001] The invention belongs to the technical field of filling liquefied hazardous chemicals, and in particular relates to an automatic loading system and a loading method for a non-leakage crane tube of a liquid chlorine tanker. Background technique [0002] Liquid chlorine medium has physical and chemical characteristics such as highly toxic, volatile, strong oxidant, combustion aid, and easy to cause explosion hazard when mixed with other flammable gases, and it is an important basic raw material, so the filling of liquid chlorine is essential . It is very important to solve the leakage problem during the filling process of liquid chlorine. At present, the filling of liquid chlorine tank trucks in China is basically done manually under the condition of metal hoses, hard pipes and ordinary loading cranes. The universal joints of the loading cranes have no leak-proof measures or anti Static electricity, anti-leakage and other safety interlock devices; ther...
