Problems solved by technology
Because some industries supporting the air separation equipment have relatively high requirements for the continuity of gas supply, once the air separation equipment shuts down in an accident, it will have a great impact on the supporting equipment, and even cause great economic losses
However, the current air separation plant is a complex system, and it is easy to shut down the equipment due to a small fault. Therefore, the reliability and stability of the backup system of the current air separation plant are not enough, and it is difficult to shut down the air separation plant when there is a problem. , let the backup system supply gas to the user uninterrupted

The invention discloses an uninterrupted backup system of air separation equipment. The uninterrupted backup system comprises a self-operated regulator, a pressure adjusting device, a pressure transducer, an electric adjusting valve, a control system, a gasified gas access end and a pressure-adjusted gas output end, wherein one way of the gas access end is connected to the gas output end by a pipe through the self-operated regulator, and the other way of the gas access end is connected to a pipe between the self-operated regulator and the pressure transducer by a pipe through the electric adjusting valve; the pressure adjusting device is connected with the self-operated regulator in parallel; and the control system is electrically connected with the electric adjusting valve and the pressure transducer. The uninterrupted backup system can uninterruptedly supply gas to users to guarantee the operation safety and stability thereof.
Description
technical field [0001] The invention relates to an air separation plant, in particular to an uninterrupted backup system of the air separation plant. Background technique [0002] Air separation equipment is the abbreviation of air separation equipment, also referred to as air separation. It is a gas separation equipment that liquefies, rectifies, and finally separates air into oxygen, nitrogen and other useful gases. Because some industries supporting the air separation equipment have relatively high requirements on the continuity of gas supply, once the air separation equipment shuts down in an accident, it will have a great impact on the supporting equipment, and even cause great economic losses. However, the current air separation plant is a complex system, and it is easy to shut down the equipment due to a small fault. Therefore, the reliability and stability of the backup system of the current air separation plant are not enough, and it is difficult to shut down the ai...
