Embodiment Construction

[0014] The present invention is further illustrated below by specific examples.

[0015] A method for the protective removal of a large oxygen turbocompressor package comprising

[0016] Step 1. Preparation for dismantling: confirm energy-medium isolation and set up the operation platform. The operation platform is set up on the side of the compressor rotor, and the height is consistent with the height of the compressor foundation;

[0017] Step 2, electrical instrument system detection: including the detection of sensors, local transmitters and connected control lines;

[0018] Step 3. Dismantle the electrical instrument system; when dismantling, first remove the sensor, then dismantle the local transmitter, connect the control line, and the cable tray in sequence;

[0019] Step 4. Piping system removal; including dismantling the cooling water pipe, lubricating oil pipe and instrument air pipe, among which, first remove the cooling water pipe, then remove the lubricating oil...

Abstract

The invention belongs to the construction field of compressor units, and particularly relates to a protective demolition method for a large oxygen turbine compressor unit. The protective demolition method is characterized by comprising the steps that demolition preparation is conducted; an electrical instrument system is detected; the electrical instrument system is demolished, specifically, during demolition, a sensor is demolished firstly, and then an in-place transmitter, a connecting control line and a cable bridge are demolished sequentially; a pipeline system is demolished, specifically,a cooling water pipe, a lubricating oil pipe and an instrument air pipe are demolished; a coupling is demolished; a compressor, a main motor, an oil tank and a cooler are demolished synchronously; and finally, an air inlet, an exhaust opening, a water inlet and a draining opening of the cooler are all sealed, wherein the air inlet and the exhaust opening are subjected to nitrogen sealing. According to the protective demolition method, the large oxygen turbine compressor unit is demolished through the six steps, the core parts are protected in a pointed mode, thus equipment integrity and cleanliness are effectively ensured, the cleaning workload during re-construction installation is substantially decreased, and the protective demolition method is a new demolition technology of the large oxygen turbine compressor unit.

Description

technical field [0001] The invention belongs to the construction field of compressor units, in particular to a method for protective removal of large oxygen turbine compressor units. Background technique [0002] The oxygen turbine compressor unit is the most important equipment for the production of finished oxygen in the air separation equipment, and its installation quality directly affects the safe operation effect of the compressor and the quality of the product oxygen. With the technological transformation and upgrading of air separation equipment, more and more protective demolition and reconstruction of oxygen turbine compressor units are carried out. However, the oxygen turbine compressor unit has a lot of precision equipment, and the protective removal is difficult, and the operating medium is oxygen, so the requirements for the cleanliness of the removal process are very high. At present, there is a lack of efficient protective removal methods for large oxygen tu...
