A driving control device and method for a liquefied natural gas tanker

Abstract

The invention discloses a driving control device and method for a liquefied natural gas tank car. The device comprises low-temperature liquid level sensors, a horizontal acceleration sensor and a data processor, wherein the low-temperature liquid level sensors are arranged at the two ends of a container in a tank and used for collecting liquid level information of liquefied natural gas in the tank; the horizontal acceleration sensor is arranged on the rear portion of a tractor and used for monitoring real-time driving condition of the car; and the data processor is arranged beside an operator seat in a tractor head of the tractor, and the input end of the data processor is connected with the output ends of the low-temperature liquid level sensors and the output end of the acceleration sensor. By the adoption of the driving control device and method for the liquefied natural gas tank car, impact damage caused by fluid inertia to fixed structures of the tank is effectively reduced, and more severe gasification, caused by rolling of low-temperature fluid, of the liquefied natural gas is effectively relieved, so that safe and reasonable driving of the liquefied natural gas tank car is achieved.

Description

technical field [0001] The invention relates to the field of liquefied natural gas transportation, in particular to a control method and device for the running process of a liquefied natural gas tanker. Background technique [0002] LNG transportation is a key process in the downstream application of the natural gas industry. It connects LNG storage stations and urban LNG filling stations. Tank trucks are usually used for land transportation, which is flexible and fast. However, since the storage environment of liquefied natural gas is -162°C and stored in atmospheric pressure storage tanks, the gasification phenomenon caused by factors such as wall surface heat transfer and vibration during transportation cannot be ignored. The gasified natural gas must be discharged, otherwise it will Causes tank pressure to be too high. Therefore, how to reduce the amount of gasification in the transportation process of LNG tankers, reduce the waste of resources, and improve the safety f...
