Abstract

The invention discloses a BDO device hydrogen compressor high-pressure oil injection structure which comprises a high-pressure oil injection joint and a high-pressure oil injection pipe. The high-pressure oil injection pipe is made of 1Cr18Ni9Ti stainless steel, the high-pressure oil injection joint is a rigid planar seal joint, and the high-pressure oil injection pipe is welded with the rigid planar seal joint. By transforming an original connecting mode, shutdown maintenance caused by detonation of an oil injection hose and separation of the joint is avoided, unit operation cycle is shortened, and operation consumption is reduced.

Description

technical field

[0001] The invention relates to a high-pressure oil injection structure of a hydrogen compressor of a BDO device. Background technique

[0002] The hydrogen compression section of the BDO plant is equipped with two hydrogen compressors. The unit is a six-row symmetrical balanced reciprocating piston compressor. The maximum pumping capacity of a single unit is 250kg / h. During the production process, the unit has a sixth-stage outlet pressure of 20.0MPa and a seventh-stage outlet pressure Reach 30.0MPa. The fuselage side of the 6 / 7-stage cylinder body of the unit is sealed with packing. The stuffing box is designed with interfaces such as cooling water, sealing nitrogen and high-pressure oil injection. / 4NPT conical union. The design pressure of this stainless steel rubber-lined metal hose is 42.0MPa, which can withstand the high pressure on the material side, but the hose bursts due to the aging of the rubber lining under high temperature and high pressure c...
