All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprising" and "having," as well as any variations thereof, in the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The invention provides a safety prevention system for multi-type intermodal transportation railway transportation of LNG tanks, which comprises the following components as shown in figures 1-4:
the special railway line network is a railway transportation network consisting of a plurality of LNG special railway lines determined by review and emergency disposal sites arranged in the railway transportation network, wherein the emergency disposal sites are provided with BOG emergency treatment equipment, and the BOG emergency treatment equipment comprises BOG reliquefaction recovery equipment and a natural gas discharge torch system. The BOG reliquefaction recovery device uses a large-cold-capacity cryogenic refrigerator as a cold source, BOG gas is condensed and liquefied through heat exchange with the BOG gas, and the BOG gas returns to the tank after being liquefied. The BOG pressure in the tank is effectively reduced, the temperature of LNG is reduced, and zero emission recovery of the BOG is realized. The natural gas discharge flare system introduces the BOG with overpressure in the tank into the natural gas discharge flare system, and the pressure is quickly reduced in a controllable combustion mode. Effectively avoids the direct air discharge of the BOG to cause environmental pollution, energy waste and potential safety hazard. And when the distance of the LNG special railway line is greater than the length threshold value of 1000km, at least 1 emergency treatment station is arranged, and the emergency treatment station is arranged at a station in front of a long tunnel, a tunnel group and other heavy-point safety places.
LNG tank, it is the carrier of LNG multimodal intermodal railway transportation. In order to ensure the safety of the LNG tank, the standards, structural design, material selection, and processes and equipment related thereto are required to primarily function to reduce heat input and delay the generation of BOG. For the convenience of monitoring and guaranteeing the safety of the LNG transportation process, the LNG tank is selected according to a tank classification standard, and the grade of the LNG tank is divided according to the LNG lossless storage time as a reference according to the tank classification standard. As shown in fig. 2, it is required that: the nondestructive storage time is more than 60 days, the grade A is permitted to be applied to ocean shipping, the grade A is A + in more than 70 days, and the grade A is A + +, in more than 80 days. The nondestructive storage time is more than 30 days and less than 60 days, the grade B is used for inland transportation, the grade B is B + in more than 40 days, and the grade B is B + + in more than 50 days. The lossless storage time is C-level when the storage time is more than 10 days and less than 30 days, and the operation can be carried out in a province; the lossless storage time is less than 20 days and is C-, urban operation is permitted, and a maintenance instruction is sent. The lossless storage time is D grade less than 10 days, and the use is forbidden. The medium of warehousing and transportation in the LNG tank case is low temperature LNG, and LNG medium safety is the key of LNG railway transportation safety. LNG medium safety depends on changes in physical parameters. Due to the wide variety of LNG production locations and process variations, LNG varies in composition, temperature and pressure. Therefore, LNG product profiles need to be established on a batch basis.
The LNG tank is provided with a liquid level meter, a temperature sensor, a pressure sensor, a gas leakage alarm and a GPS/Beidou positioning device which are connected with the LNG train monitoring platform. The system has the functions of realizing remote data transmission, real-time monitoring, overrun alarm and the like. All factory information of the LNG tank, including structural design, material selection, performance parameters and the like, need to be independently filed, and all information after delivery and use must be monitored in real time by a monitoring platform to construct a first barrier of a safety system.
An LNG carrier comprising an LNG train and a transfer means for carrying and transporting the LNG tank in a dedicated railway line network; the transfer tool is arranged in a station and comprises tools such as a traction locomotive, a flat car and a gantry crane. In order to ensure the safety of the LNG transportation equipment, it is required that transportation tools of LNG trains and stations, etc. must be configured with fire-fighting facilities according to the requirements of flammable and explosive media, and executed according to the conventional requirements of railway safety to make corresponding safety precautionary measures.
The safety monitoring system comprises an LNG train monitoring platform and a monitoring center;
and the LNG train monitoring platform is positioned on the LNG train, monitors and collects the safety data of the LNG tank and the LNG transport device in real time, and transmits the safety data back to the monitoring center.
The monitoring center is used for collecting the safety data sent by each LNG train monitoring platform and carrying out real-time monitoring and scheduling on the special railway line network and the LNG trains. The pressure and temperature changes in the process of warehousing, shipping, transportation and unloading of the LNG medium are monitored in real time through a monitoring center, and data recording is carried out by adopting a block chain technology.
During transportation of the LNG tank, the LNG continuously absorbs heat from the outside and changes into BOG (boil off Gas), and the pressure of the Gas in the tank gradually increases. When the BOG pressure reaches the take-off pressure of the tank safety valve, the safety valve is opened, the BOG is discharged from the tank, a large amount of resources are wasted, meanwhile, the environmental pollution is brought, and serious safety accidents can be caused due to improper treatment.
In order to avoid safety accidents, the whole process of transporting the LNG tank is subjected to real-time grading monitoring, and the monitoring is shown in figure 4. The pressure value in the LNG tank box is monitored through a pressure sensor (primary monitoring), an LNG train monitoring platform (secondary monitoring) acquires the pressure value of the pressure sensor, and an alarm is sent to a monitoring center (tertiary monitoring) according to the pressure value. The safety of the LNG tank is judged according to a traffic light alarm mechanism and a pressure value;
the traffic light alarm mechanism has the following rules: when the pressure value is less than or equal to 0.4MPa, the lamp is in a normal use state; when the pressure value is more than 0.4MPa and less than 0.7MPa, the lamp is yellow, and the treatment plan needs to be made; when the pressure value is greater than or equal to 0.7MPa, the lamp is red, and the lamp needs to be immediately treated according to a preset scheme;
the LNG train monitoring platform is configured to: when the yellow light is emitted, a yellow light alarm is sent to the monitoring center and an acousto-optic alarm is generated, and when the red light is emitted, a red light alarm is sent to the monitoring center and an acousto-optic alarm is generated;
the monitoring center is configured to: when a yellow light alarm is received, the LNG tank is transferred to an emergency disposal site, and BOG reliquefaction recovery equipment is arranged for reliquefaction and cooling treatment; when a red light alarm is received, the LNG tank is transferred to an emergency disposal site, a natural gas discharge torch system is arranged for combustion and pressure reduction, and when a yellow light alarm is received, the BOG reliquefaction recovery equipment is used for reliquefaction and temperature reduction treatment. When the BOG pressure in the LNG tank box is reduced to a green light area, the BOG is online to participate in normal transportation, so that the transportation safety and medium safety in the LNG transportation process are ensured.
In fig. 3, the transportation security is strictly managed by the consignor, the carrier, and the receiver according to the division link and the scope. Safety detection, filling and unloading are carried out by the LNG operators in the logistics nodes, and safety certificates of the tanks need to be confirmed before LNG filling. The railway freight yard loading and unloading safety and logistics distribution management are responsible for railway departments, and before the freight yard is conveyed to the freight yard for loading, the communication between all instrument information of the tank and the monitoring room needs to be verified in time, accurately and completely and is in a safe state. During transportation, if a safety warning occurs, the system needs to follow the instructions of the monitoring center to carry out throwing and hanging treatment at the nearest emergency treatment point. When the destination storage yard is reached, the safety detection process is required to be implemented to confirm that the safety party can send out the delivery notice. The dump safety mainly refers to the safety of the station, the yard and the like in fig. 2. The technical safety protection is mainly required, the safe technical conditions of the LNG tanks of the wharf, the storage yard and the station are formulated, and the safety of the storage state is realized. According to the specification of 5.3.6 in the safety regulations on dangerous cargo container port operation, LNG tanks should not be stacked on each other, and should be placed on the uppermost layer when stacked with other non-flammable and non-combustible dangerous cargo containers.
The integrated box, vehicle and road in the invention is an important support for LNG railway transportation safety, the safety monitoring system is a foundation stone for LNG railway transportation safety, various data signals in the transportation process of the LNG tank box are monitored in real time through the safety monitoring system, data are recorded and processed, and LNG transport trains are monitored and scheduled, so that abnormal conditions are discovered, reminded, early-warned and disposed in time, and BOG safety and centralized processing are realized, thereby guaranteeing the LNG railway transportation safety.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
