When a general chemical plant loads liquid chlorine, a large amount of tank trucks are needed for queuing and filling due to a large output. However, in the existing liquid chlorine filling process, the tank truck driver can only be informed by personnel or follow the driving progress of the previous vehicle to queue and fill. Since the general tank truck capacity is large and the filling time is long, a long waiting time is required, which wastes a lot of time in the waiting process and cannot fully utilize the time.

[0003] The liquid chlorine tank truck non-leakage crane pipe automatic loading system and its loading method with publication number CN103939735B are proposed to connect the liquid chlorine tank on the tank truck and the user's liquid chlorine storage tank for liquid chlorine loading operation. A liquid phase filling port and a gas phase back suction port are provided on the top of the liquid chlorine tank of the tank truck. The liquid phase filling port is connected with the liquid chlorine storage tank through a liquid chlorine liquid phase non-leakage crane pipe, and the gas phase back suction port is connected with a chlorine gas recovery treatment device through a liquid chlorine gas phase non-leakage crane pipe. The present application is mainly applied to the process of filling liquid chlorine into the tank truck through the non-leakage crane pipe. The explosion-proof batch controller is used to switch the gas-actuated stop valve to realize the filling and overloading back suction of liquid chlorine. At the same time, the explosion-proof batch controller is used to detect the pressure, temperature, and flow of liquid chlorine and gaseous chlorine in each pipeline to realize automatic metering, quantitative control, and safety detection interlocking during the filling process.

[0004] However, the loading system proposed in the present application cannot predict the queuing process and specific waiting time of the queuing vehicles, and the tank truck drivers and staff cannot effectively check the queuing process and specific waiting time. The waiting time for filling is not fully utilized, and the drivers waste a lot of waiting time.

[0006] But the invention for liquid chlorine leak adopts one-key cut-off input, if it is applied to liquid chlorine filling, the pause in the case of liquid chlorine leak in liquid chlorine filling will make the filling truck unable to drive away from filling workshop because of incomplete filling or connecting pipeline cannot determine pipeline leakage point, cause tank truck to be stranded, will cause unnecessary trouble to subsequent leak repair.

[0046] According to another aspect of the present application, a method for intelligent liquid chlorine interlocking filling and loading is provided, comprising the following steps:

[0047] S101: The prepared liquid chlorine is introduced into the liquid chlorine tank 1 through the liquid inlet 101. Before loading, all pneumatic stop valves 105 and pneumatic regulating valves are fully closed. When loading is required, the second temperature sensor 204 and the second pressure sensor 205 provided on the tank car 2 are used to determine whether the tank space meets the storage conditions for liquid chlorine transportation.

[0048] S102: If the conditions are met, the air compressor 402 of the low-temperature transmission pipe 4 is started to ventilate the vortex pipe 401, so that the cold end outlet 403 and the hot end outlet 404 generate cold flow and hot flow respectively. The cold flow is transmitted through the pipeline to the hollow pipe 407, and the hollow pipe is in direct contact with the inner pipe 408, which is a good heat-conducting material, so that the temperature of the inner pipe 408 is reduced to below the boiling point of liquid chlorine. At the same time, the hot flow is transmitted through the pipeline to the heat energy storage tank 406 for energy storage for the production of liquid chlorine. Then the shield pump 3 is started by the DCS control center 6. After the shield pump 3 is opened, the second pneumatic stop valve 106 and the third pneumatic stop valve 202 are opened, and the second pneumatic regulating valve 108 and the third pneumatic regulating valve 203 are opened.

The real-time data is processed by the information processing center 7 and uploaded to the cloud server 9 by the wireless transmission module 8. The mobile phone APP module 11 and the computer web module 12 can download the data from the cloud server 9 to view the loading progress of the liquid chlorine. Since the tank capacity of the tank car 2 is fixed and the transmission efficiency of the shield pump 3 is fixed, the tank loading time can be predicted by volume capacity algorithm, and the prediction result can be displayed on the mobile phone APP module 11 and the web module 12. At the same time, the number of tank cars 2 in front of the queue is counted, and the specific queuing time of the tank car 2 is predicted and displayed according to the queuing situation, so as to improve the time management and queuing efficiency of the tank car 2 driver.

[0050] S104: The chlorine concentration detector 501 installed on each instrument flange and valve flange and pipe section can detect the chlorine concentration nearby. When the chlorine concentration exceeds the standard, the chlorine concentration detector 501 transmits an electrical signal to the sound and light alarm 508 to produce a sound and light alarm. At the same time, all pneumatic stop valves, pneumatic regulating valves and shield pumps 3 are closed. The chlorine leakage position is determined according to the chlorine concentration detector 501 at different positions, and then sent to the DCS control center 6. Then the vacuum pump connected to the vacuum suction nozzle 502 is opened, so that the absorbed gas is transmitted to the caustic soda pool 503 for harmless treatment of the leaked chlorine. At the same time, the sprayer 506 sprays the entire indoor tank filling workshop to treat the chlorine in the air and prevent toxic gases from affecting the atmospheric environment. At the same time, the exhaust fan 509 starts to exhaust indoor air to the caustic soda pool 503, thereby preventing the escape of chlorine in the indoor air. The bottom of the entire tank filling workshop is provided with a drainage system to discharge the wastewater sprayed by the sprayer 506, and finally introduced into the wastewater recovery pool 507 for centralized treatment of wastewater containing chlorine. According to the segmented detection of the chlorine concentration detector 501, the chlorine leakage position can be determined. If the leakage position is located at the rear end of the pneumatic three-way switch valve 504 and the front end of the third pneumatic stop valve 202, the transmission pipeline can be switched to the standby pipeline 505 at the early stage of leakage by switching the pneumatic three-way switch valve 504. One end of the standby pipeline 505 is arranged at the switching end of the pneumatic three-way switch valve 504, and the other end is arranged at the rear end of the third pneumatic stop valve 202. Therefore, only the second pneumatic stop valve 106 and the third pneumatic stop valve 202 need to be closed when leakage occurs, and then the standby pipeline 505 is used to continue to transmit liquid chlorine. After the tank truck 2 finishes filling the liquid chlorine, the equipment is stopped, and then the maintenance personnel can maintain it, so that the tank truck 2 cannot complete the filling due to leakage during filling, and the equipment maintenance difficulty caused by staying in the tank filling workshop is avoided.

[0051] The volume capacity algorithm, i.e. the capacity of the tank truck 2 divided by the speed of the shield pump 3, can obtain the filling time of one truck.
