Abstract

The invention discloses an oxygen partial pressure supply system. The oxygen partial pressure supply system comprises an oxygen compressor set and a depressurization station; and the oxygen partial pressure supply system is characterized in that the oxygen compressor set comprises a first oxygen compressor, a second oxygen compressor, a third oxygen compressor and a fourth oxygen compressor. The four oxygen compressors are connected with a medium pressure oxygen pipe through pipes; an oxygen turbocompressor is further connected to the medium pressure oxygen pipe to press out supplied 2.0 MPa oxygen, the medium pressure oxygen pipe is then connected to the depressurization station for oxygen depressurization, and the depressurized oxygen is conveyed to be used for steelmaking; and meanwhile, the oxygen compressor set is further provided with a pipe to be connected to a low-pressure oxygen pipe to press out the oxygen which is 0.8-1.0 MPa and 10000 m<3>/h, and the oxygen is directly supplied to iron making and steel rolling. According to the oxygen partial pressure supply system, a special low-pressure oxygen pipe is arranged, depressurization supply after oxygen pressurization is not needed, the oxygen supply procedure is simplified, energy consumption is effectively reduced accordingly, the production cost is reduced, energy conservation and environment protection are achieved, the safety of the low-pressure oxygen pipe is higher, and the running period is longer.

Description

technical field [0001] The invention relates to the technical field of steelmaking oxygen supply, in particular to an oxygen partial pressure supply system. Background technique [0002] The oxygen workshop uses air separation technology to produce oxygen, nitrogen, and argon for the use of various users in the company. There are many places where oxygen is used in ironworks, and the pressure requirements for oxygen are different. All of them are reduced to achieve energy-saving power. the goal of. [0003] The oxygen pipe network of the oxygen production station uses a DN400 pipeline to supply the iron and steel making units through the step-down station of 20,000 units, and the pressure is maintained above 1.6Mpa (after step-down in the station). According to the survey and analysis of gas supply this year, the actual average oxygen consumption of ironmaking and steel rolling is about 13,000 m3 / h, and the actual average oxygen consumption of other units such as steelmakin...
