Anti-clogging steam jet for steam turbine and working method

Abstract

The invention relates to an anti-clogging steam jet for a steam turbine and a working method and belongs to the technical field related to steam turbines. In order to solve the problems that existinganti-clogging steam jets for steam turbines are easy to be rusted, the generated impurities are easy to block the device, it is inconvenient to disassemble and clean the device, and existing anti-clogging steam jets are easy to be influenced by cold shrinkage and thermal expansion then cause liquid leakage. The anti-clogging steam jet for steam turbine comprises a first pipe and a second pipe, theouter side of the first pipe is closely fitted with an outer pipe, the upper end of the first pipe is fixed with a flange, the outer side of the lower end of an air inlet pipe is provided with a spring, the lower end of the air inlet pipe is connected with a first air injection plate, under the first air injection plate is equipped with a first filter plate and a second filter plate. The inner bottom end of the first pipe is provided with a connecting block, the second pipe is fixed at the lower end of the mounting pipe, and the outer side of a sealing plate is equipped with a salient point.Inside the anti-clogging steam jet for steam turbine is provided with a purification and a filter device, the anti-clogging steam jet for steam turbine is not easy to be blocked, it is easy to disassembly and clean the anti-clogging steam jet for steam turbine, and the anti-clogging steam jet for steam turbine is provided with a thermal insulation device which is not easily affected by cold shrinkage and thermal expansion then causes liquid leakage.

Description

technical field [0001] The invention relates to the technical field related to steam turbines, in particular to an anti-clogging steam nozzle for steam turbines and a working method thereof. Background technique [0002] Steam turbines can be used to provide power for generators, compressors, pumps and other equipment, and can be used in power plants, chemical plants, sugar factories, textile mills, etc. The interior of a steam turbine generally includes a steam generator, which converts water into steam by heating, The steam turbine converts the energy contained in the steam into kinetic energy to drive various equipment. There are stationary blades on the cylinder block and moving blades on the rotor in the steam turbine. [0003] Multiple valves need to be installed at the air inlet of the steam turbine to control the steam entering the steam turbine. Generally, steam nozzles for steam turbines with anti-clogging are prone to rust inside, and the generated impurities are ...
