[0003] The liquid storage tank is the key equipment in the air separation industry. The liquid oxygen in the storage tank comes from the liquid oxygen evaporator in the air separation cold box. After the liquid oxygen flows into the liquid oxygen storage tank from the liquid oxygen evaporator, the pressure drops, causing some liquid Oxygen flash vaporization, plus the self-evaporation loss of the liquid oxygen storage tank itself, a certain amount of gas and oxygen will be discharged into the atmosphere through the vent valve on the top of the liquid oxygen storage tank every hour, resulting in a large economic loss; In addition, the oxygen used by the converter and the electric furnace is supplied by the same oxygen buffer tank. Due to the large oxygen consumption and low pressure of the converter and the low oxygen consumption and high pressure of the electric furnace, the oxygen buffer tank must maintain a high pressure to meet the A small amount of oxygen is used in the electric furnace, and a large amount of oxygen is supplied to the converter after throttling, resulting in increased energy consumption of the oxygen compressor

The invention relates to the technical field of liquid oxygen storage, and discloses a liquid oxygen storage-based oxygen safety recovery system, which comprises an oxygen buffer tank, a liquid oxygen storage tank, a recovery tank, an oxygen compressor, a first detection box, a first sealing box and a second sealing box, a gas conveying pipe is connected between the oxygen buffer tank and the oxygen compressor, a liquid oxygen pipe is fixedly installed on one side of the front face of the liquid oxygen storage tank, a second connecting pipe is fixedly installed on one side of the liquid oxygen storage tank, a first connecting pipe is fixedly installed on one side of the recovery tank, one end of the second connecting pipe is connected with one end of the first connecting pipe, and the other end of the second connecting pipe is connected with the other end of the recovery tank. And a second detection box is fixedly mounted on the other side of the recovery tank. According to the safe oxygen recovery system based on liquid oxygen storage, gasified and evaporated liquid oxygen in the liquid oxygen storage tank can be effectively recycled, economic loss is reduced, the recycled liquid oxygen can be provided for oxygen for a converter, and energy consumption of an oxygen compressor is reduced.
Description
technical field [0001] The invention relates to the technical field of liquid oxygen storage, in particular to an oxygen safety recovery system based on liquid oxygen storage. Background technique [0002] With the continuous development of my country's industrial production, the cryogenic liquid market has become increasingly prosperous, and the sales of liquid oxygen, liquid argon, and liquid nitrogen have increased significantly. Therefore, the profit-making in the air separation industry is very considerable and has become an important source of profit income. Production, storage and transportation are inseparable from thermal insulation storage tanks, so that thermal insulation storage tanks are installed and used in large numbers. [0003] The liquid storage tank is the key equipment in the air separation industry. The liquid oxygen in the storage tank comes to the liquid oxygen evaporator in the air separation cold box. After the liquid oxygen flows from the liquid oxy...
