Description

A railway tank car oil unloading system

Technical Field

The invention relates to the technical field of petroleum and natural gas industry, and in particular to an oil unloading system for a railway oil tanker.

Background Art

At present, the trestle operation in railway oil unloading operation and the traditional railway tank car loading and unloading operation are the operations with the lowest degree of modernization and the most intensive manpower input. The operating environment is complex, and monitoring cannot be implemented during the operation. There are no sensors or electric equipment. All operations must be completed manually by employees. The frequency of manual inspections is 2 times/hour. Operating employees frequently get on and off the tank cars, which takes up a lot of human resources. In addition, there is a risk of falling for operating personnel and they will inevitably inhale oil vapor. The equipment operation risk and personnel health hazard are both relatively large. In addition, the water in the traditional water ring vacuum pump may be too hot during long-term use in summer, causing water vapor evaporation and affecting the vacuum extraction efficiency. If the warming measures are not in place in winter, the equipment may be frozen, and a large amount of water resources are consumed, which is not environmentally friendly.
