Oxygen pipeline system and anti-flammation device for super-large converter oxygen lance valve station

Abstract

The invention relates to oxygen pipeline system and anti-blasting device of an extra-large converter oxygen lance valve station and belongs to auxiliary devices for a converter oxygen lance valve station.The oxygen pipeline system and anti-blasting device are characterized by comprising: an oxygen dedicated stop valve I, an oxygen flame arrester I, an oxygen observation dedicated filter, an oxygen dedicated pneumatic cut-off valve I, an oxygen flame arrester II, an oxygen dedicated pneumatic regulating valve I, an oxygen flame arrester III, an oxygen dedicated flow orifice plate I, an oxygen dedicated stop valve II, an oxygen dedicated flow orifice plate II, an oxygen flame arrester IV, an oxygen dedicated pneumatic regulating valve II, an oxygen flame arrester V, an oxygen dedicated pneumatic cut-off valve II, an oxygen dedicated check valve and an oxygen flame arrester VI, which are connected in succession through a pipeline.The oxygen pipeline system and anti-blasting device are reasonable in structure and safe and reliable to use, the problem with safety in using oxygen in an extra-large converter oxygen lance is solved, and normal running of the converter oxygen lance valve station is guaranteed.

Description

technical field [0001] The invention belongs to an accessory device of a converter oxygen lance valve station, and in particular relates to an oxygen pipeline system and an explosion-proof device of a converter oxygen lance valve station. Background technique [0002] In the current steelmaking system, more and more super-large converters are used at home and abroad (a converter with a design capacity greater than or equal to 350 tons is called a super-large converter), while in the previous steelmaking system, 100 tons, 120 tons, 150 tons The oxygen pipeline system of the oxygen lance valve station used in the 1-ton, 200-ton and 300-ton steelmaking systems is a small oxygen lance valve station system for a smaller converter. The structure of the oxygen regulating valve group is detailed in the magazine "Safety Technology" in 2013 Issue 01, the page number of the article content: 9 to 16, the author is Ma Dafang, Wuhan Iron and Steel Group Oxygen Co., Ltd.

AI Technical Summary

Problems solved by technology

[0003] The small oxygen lance valve station system is no longer suitable for the needs of super-large converters. There are many disadvantages in the use of the small oxygen lance valve station system. Sparks are generated, which leads to the explosion phenomenon of the oxygen lance valve station system. The accidents of the valve station pipeline explosion have occurred many times because the sundries in the pipeline cannot be cleaned. Therefore, the use of the small oxygen lance valve station system in the past has changed from the oxygen pipeline The safety facilities of the system and the use of filter types are no longer suitable for the safety requirements of super-large converters
