According to the hot washing flue gas turbine descaling device based on the blade thermal expansion coefficient, the novel structural design is adopted, the device conducts descaling machining on a flue gas turbine in a working state in a heat treatment mode, and operation is convenient and fast; and a catalytic fluegas pretreatment structure is arranged in the device, the influence of catalytic flue gas on an impeller is reduced, and use functionality of the device is increased.

Description

technical field [0001] The invention relates to the technical field of flue gas turbines, in particular to a thermal scrubbing flue gas turbine descaling device based on the thermal expansion coefficient of blades. Background technique [0002] Flue gas turbine is a kind of mechanical equipment driven by high-temperature and low-pressure flue gas produced by catalysis. Long-term operation of flue gas turbine will cause problems. There are many reasons that affect the operation of flue gas turbine in catalytic cracking unit. In this aspect, the flue gas contains a part of catalyst fine powder, which will deposit scale on the blades of the flue gas turbine under the influence of some factors, destroying the dynamic balance, causing the vibration value to rise and shutting down. When the gas turbine is working, the descaling device can be used to process the impeller rotor at the same time, so as to maintain the normal operation of the equipment. [0003] With the continuous p...
