Description

Technical Field

[0001] The invention relates to the technical field of diaphragms in the maintenance of dry coke quenching steam turbines in the coal coke chemical industry, and in particular to a device and method for removing diaphragms from steam turbines. Background Art

[0002] The turbine diaphragm is a circular plate-shaped component installed in the turbine cylinder and divides the cylinder into several chambers with different pressures. Its main function is to install nozzles or stationary blades and prevent interstage steam leakage. When the steam working medium flows through the nozzle installed on the diaphragm, the potential energy is converted into kinetic energy, the pressure is reduced, the speed is increased, and then it enters the moving blades to do work. The diaphragm is installed in the groove of the inner wall of the cylinder, generally divided into upper and lower halves, straddling the rotating shaft, and the rotating shaft passes through its center. The diaphragm is subjected to the load generated by the pressure difference during operation. The diaphragm working in the high-pressure part is subjected to the action of high-temperature and high-pressure steam, and the diaphragm working in the mortgage part is subjected to the action of wet steam. The stationary blades on the turbine diaphragm are usually fixedly connected to the diaphragm by welding. During operation, since the stationary blades are subjected to the impact of high temperature and high pressure for a long time, and since the stationary blades and diaphragms are also integrally formed, whether the stationary blades or diaphragms are damaged or deformed, they must be replaced as a whole.

[0003] In the prior art, the conventional method of removing the partition is to use a crane to hang the partition and vibrate it with a copper rod. If it is not very tight, it can generally be slowly removed. However, during the process of uncovering the steam turbine for maintenance, the partition is often subjected to high temperature, high pressure, corrosion and erosion by water droplets in the wet steam zone for a long time, which easily produces oxide scale, scale or rust on the surface, causing the partition back arc to be stuck and separated from the mounting groove, making it difficult to remove normally, affecting the maintenance process.

[0004] In view of the above factors, a steam turbine partition removal device and method are provided, which can greatly improve the maintenance efficiency, reduce labor intensity, not damage the partition and can be removed smoothly, reduce the partition scrap rate, and ensure the reuse of the partition.
