Description
Technical Field
The invention relates to the technical field of maintenance, in particular to a method for quickly removing a turbine expander.
Background
In the metallurgical industry, a large amount of raw gas is generated in the production process of a blast furnace, the pressure is generally 0.2-0.25 MPa, and the pressure of the gas is reduced to 10Kpa before the gas is incorporated into a gas pipe network, so that the pressure reduction treatment is necessary. The conventional process configuration is realized by adopting a coal gas residual pressure recovery turbine power generation system. The main equipment of the coal gas residual pressure recovery turbine power generation system is a turbine, the turbine is large in size and complex in maintenance flow, and a large amount of time is consumed when maintenance operation is carried out, particularly when an expander of a turbine rotor is replaced, so that the coal gas power generation amount is greatly influenced.
The expander of the turbine is of an arc-shaped structure and is assembled with the casing in an embedded mode, and the expander plays a role in guiding airflow and supporting rotating equipment. In the operation process of the turbine, the expander is influenced by acting force generated by high-temperature and high-pressure gas and high-speed operation of a rotor for a long time, the expander and the shell are attracted, when the expander needs to be disassembled, the expander is difficult to realize by adopting a conventional knocking and lifting method, and the expander is also easy to damage equipment per se by forcibly disassembling, so that the overhaul work is greatly disturbed.
