Description

Liquefied gas transport container control method, pressure control system and transport tool
Technical Field
The invention relates to the field of liquefied gas transportation, in particular to a control method of a liquefied gas transportation container, a pressure control system and a transportation tool.
Background
The railway tank has obvious advantages in transporting liquefied natural gas, conforms to the development requirements of domestic logistics, and is widely applied. However, the tank for transporting the liquefied natural gas continuously absorbs the heat of the environment in the transportation process, so that the pressure in the tank continuously rises, and therefore, a tank safety valve needs to be arranged to discharge and release the pressure of the tank. The uncontrolled discharge of the current lng tank may occur at any time. When the tank box passes through a special road section (such as a station, a tunnel, a town and the like, which is relatively closed in space or has a gathered population), the tank box performs a discharge action, so that gas can be gathered, and the explosion risk is increased.
Disclosure of Invention
The invention aims to provide a control method, a pressure control system and a transport tool for a liquefied gas transport container, and aims to solve the problems that in the prior art, the pressure relief action of a liquefied natural gas tank is not controlled, the pressure relief action can occur in a special road section, and the transport safety is influenced.
In order to achieve the above object, according to one aspect of the present invention, there is provided a control method of a liquefied gas transport container, including the steps of: step S10: measuring the pressure in the container in real time and calculating the residual time T1 for the pressure to reach the discharge pressure, and acquiring the time T2 for the container to reach a non-discharge section in real time; step S20: when T1 < T2, the operation of venting is performed when the pressure in the container reaches the discharge pressure, and when T1 is equal to or greater than T2, the operation of venting is performed before the container reaches the non-discharge section, so that the pressure in the container is kept below the discharge pressure before the container leaves the non-discharge section.
Further, the step of acquiring the time T2 when the container arrives at the non-discharge section in real time includes: t2 is obtained based on the current geographical position of the container, the position of the non-discharge section closest to the current geographical position in the passing direction, and the moving speed of the container.
Further, the non-discharge section includes: one or more of culverts, stations or towns.

Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The application provides a control method of a liquefied gas transport container and a pressure control system of the liquefied gas transport container for realizing the control method, as shown in fig. 1, the pressure control system of the embodiment includes: controller 4, pressure sensor 1, positioning sensor 2 and drive structure, pressure sensor 1 sets up on liquefied gas transport container's blast pipe and is connected with controller 4 through explosion-proof wiring pipe 3, and positioning sensor 2 sets up on liquefied gas transport means and is connected with controller 4, and drive structure connects between the valve of controller 4 and blast pipe. The controller 4 can control the driving structure to act according to the information fed back by the pressure sensor 1 and the positioning sensor 2, and further control the opening and closing of a valve on the exhaust pipe, so that the exhaust and pressure relief actions of the liquefied gas transportation container are realized.
The liquefied gas transport container of the embodiment is suitable for liquefied natural gas having combustion characteristics, and is also suitable for other products such as frozen liquefied gas, high-pressure liquefied gas, low-pressure liquefied gas, compressed gas, and ordinary liquid having volatilization characteristics. Specifically, the control method of the liquefied gas transport container of the present embodiment includes the steps of:
step S10: measuring the pressure in the container in real time and calculating the residual time T1 for the pressure to reach the discharge pressure, and acquiring the time T2 for the container to reach a non-discharge section in real time;
step S20: when T1 < T2, the operation of venting is performed when the pressure in the container reaches the discharge pressure, and when T1 is equal to or greater than T2, the operation of venting is performed before the container reaches the non-discharge section, so that the pressure in the container is kept below the discharge pressure before the container leaves the non-discharge section.
The non-discharge road section refers to a road section with relatively closed space or gathered population, such as a culvert, a station, a bridge or a town, and the like, and the gas accumulation, the explosion risk or the life of surrounding residents can be influenced by the pressure relief of the exhaust gas in the road section. Therefore, the present application proposes the above control method to avoid the above situation.
According to the physical characteristics and the thermodynamic characteristics of the transported liquid, the information such as the current environmental temperature, speed and pressure in the tank during the transportation operation, the residual time T1 when the current pressure in the tank reaches the exhaust pressure can be estimated through thermodynamic calculation such as heat transfer calculation. When T1 < T2 means that the pressure in the transport container will reach the vent pressure before reaching the non-venting section, venting may be performed in the usual manner. When T1 ≧ T2 means that the pressure in the transport container will reach discharge pressure after entering the above-mentioned non-discharge section, the dangerous situation described above will occur if the venting is performed in the usual manner, and therefore the container is vented prematurely.
By applying the technical scheme of the embodiment, the gas affecting the safety or affecting the life of residents is automatically discharged from the transport container before the transport container enters the non-discharge road section through dynamic operation, so that the gas is prevented from being discharged from the non-discharge road section, the risk of explosion caused by gas accumulation is effectively reduced, and the influence on the life of the residents at the periphery is reduced.
Specifically, the step of acquiring the time T2 when the container arrives at the non-discharge section in real time in the present embodiment includes: t2 is obtained based on the current geographical position of the container, the position of the non-discharge section closest to the current geographical position in the passing direction, and the moving speed of the container. The real-time position of the container can be realized by a system with a satellite positioning function like Beidou, GPS Galileo and the like, and the map information can utilize a Baidu map, a Gade map or other map information.
The step S20 of the present embodiment specifically includes: when T1 < T2, the pressure in the container is maintained at the pressure below the discharge pressure by repeating the operation of lowering the unit pressure in the container each time the container is discharged when the pressure reaches the discharge pressure, and discharging and depressurizing the container again when the pressure in the container is raised to the discharge pressure after the container is moved for a while. In the case of T1 ≧ T2, the vessel is circulated to discharge the gas, reducing the unit pressure in the vessel each time until the pressure in the vessel can be kept below the discharge pressure before leaving the particular route. The discharge pressure P can be preset according to the physical characteristics of the container and the characteristics of the content of the container, the pressure rise value P in the container in the process of passing through the non-discharge section can be calculated according to the length of the non-discharge section and the current vehicle speed, and then the pressure rise value P in the container in the process of passing through the non-discharge section is calculated through heat transfer, so that the pressure in the container is required to be reduced to (P-P) or lower than (P-P) before the container enters the non-discharge section under the condition that T1 is larger than or equal to T2.
When the distance between two adjacent non-discharge road sections is close and the pressure cannot be reduced to (P-P) between the two non-discharge road sections, the two non-discharge road sections can be treated as one non-discharge road section to ensure that the pressure in the container cannot reach the discharge pressure in the process of passing through the two non-discharge road sections, thereby ensuring the safety.
As shown in fig. 1, in the pressure control system of the present embodiment, the valve is a pneumatic valve 10, the driving structure includes a compressed air cylinder 7 and a solenoid valve 8, the compressed air cylinder 7 is connected to the pneumatic valve 10 through a pneumatic pipeline 9, and the solenoid valve 8 is connected to the controller 4 to control the opening and closing of the compressed air cylinder 7. When the air is exhausted and decompressed, the controller 4 controls the electromagnetic valve to be opened, compressed air is sprayed out of the compressed air bottle to push the pneumatic valve 10 to be opened, air in the container 12 is exhausted from the exhaust pipe 11, and the pressure in the container is reduced. In other embodiments not shown in the figures, the drive structure may control the exhaust by other forms of structure. In order to ensure the safe operation of the driving structure, the compressed gas cylinder 7 of the embodiment is provided with a pressure sensor 6.
As shown in fig. 1, the pressure control system of the present embodiment further includes a remote server 5, and the terminal 13 can be wirelessly connected to the controller 4 through the remote server 5, so that the transport container can be monitored and controlled at a remote location. The terminal 13 may be a computer or even a mobile terminal such as a mobile phone or a tablet.
