Embodiment Construction

[0016] 1. Meet the starting conditions of the air compressor, start the air compressor, the main operator judges to open the inlet guide vane to 30 degrees according to the sound, the inspector adjusts the oil temperature in time to ensure that it is 30-34 degrees, and inspects the operation of the air compressor on site , The main operator observes the operating data, whether the rising trend is stable, wait until the oil temperature is stable, and the temperature is not rising, check the previous normal operation record table to see whether the data is normal, and then open the V1011 (air-opening control valve; air is out of the air compressor) Pneumatic control valve) inflate to the molecular sieve; start to increase the pressure to 0.35 MPa to establish the air cooling tower liquid level, and the air compressor to increase the pressure to 0.45 MPa again, and conduct the instrument air. Open V1216 (manual gate valve; air pressure reduction as regeneration gas), use air as reg...

Abstract

The invention relates to a starting method for rapid oxygen outflow. The copious cooling liquid pumping and rapid oxygen outflow starting method is adopted, oxygen outflow reaches the standard safely in 24 hours, time is shortened by half, power consumption is reduced by 60,000 kilowatt-hour, and 9 cubic meters of liquid oxygen is additionally used.

Description

Technical field [0001] The invention belongs to the field of cryogenic oxygen production, and particularly relates to a method for starting cryogenic liquid injection and rapid oxygen production. Background technique [0002] In the past, copper smelting used air oxidation, the oxygen content in the air was 20.95%, the oxygen purity was low, the oxidation reaction to copper smelting was slow, and the corresponding production cost was high. The purity of oxygen produced by the oxygen production system is over 99%, which greatly increases the oxidation reaction speed during copper smelting and reduces production costs. [0003] However, the current oxygen generation systems in the prior art often have the disadvantages of long cryogenic start-up time (48 hours), slow oxygen production, and high power consumption during start-up (more power consumption of 60,000 kWh). Summary of the invention [0004] In order to solve the above-mentioned defects in the prior art, the present inventio...
