Emergency gas supply system for high-purity ammonia tank car

Abstract

The invention provides an emergency gas supply system for a high-purity ammonia tank car. The system comprises a gas supply tank car and a spare tank car; a first heater, a first water tank as well asa first spiral heating coil water outlet pipe and a first spiral heating coil water inlet pipe which are located inside the gas supply tank car are arranged on the gas supply tank car; a second heater, a second water tank as well as a second spiral heating coil water outlet pipe and a second spiral heating coil water inlet pipe which are located inside the spare tank car are arranged on the sparetank car; the first heating coil water inlet pipe communicates with the second heater through a water inlet pipeline; and the first heating coil water outlet pipe communicates with the second heaterthrough a water outlet pipeline. In case of emergencies such as failure of the first heater and the like, the second heater of the spare tank car is directly switched and used for heating the gas supply tank car, normal gas supply is guaranteed, the switching process is simple and stable during actual operation, and normal gas supply is not affected.

Description

technical field [0001] The invention belongs to the field of gas supply systems for high-purity ammonia tank cars, and relates to an emergency gas supply system for high-purity ammonia tank cars. Background technique [0002] In recent years, with the vigorous development of LED, the usage of its auxiliary gas high-purity ammonia has increased greatly. The transportation and gas supply methods of high-purity ammonia have also undergone tremendous changes, from the original cylinder transportation and gas supply to tank truck transportation and gas supply. Usually at the gas supply site, the tanker is used for one backup or multiple backups to ensure continuous gas supply. When the tank car in use has abnormal conditions or the liquid level reaches the lower limit, the general measure is to switch to the spare tank car to achieve continuous gas supply. [0003] The high-purity ammonia tank car is pressure equipment, and the tank car itself is also equipped with correspondin...

AI Technical Summary

Problems solved by technology

Once the heater fails, it will directly affect the customer's gas consumption. The customer will choose to switch to the tank car, return the faulty tank car or handle customer complaints, which will cause great losses to both the gas supply and the gas user.
