Steam turbine blade scaling cleaning device

Abstract

The invention provides a steam turbine blade scale cleaning device which comprises a cleaning box, a blade shaft is transversely placed in the middle of the cleaning box, through holes are formed in the two ends of the cleaning box, the two ends of the blade shaft extend out of the cleaning box through the through holes, a mounting plate is arranged on the upper side in the cleaning box, a cleaning column is arranged at the lower end of the mounting plate, and a steel brush is arranged on the surface of the cleaning column. A water tank is arranged at the bottom in the cleaning box, cleaning liquid is injected into the water tank, the cleaning column is of a hollow structure, a plurality of water outlet holes are formed in the surface of the cleaning column, a circulating water pipe is arranged on the left side of the water tank, the upper end of the circulating water pipe extends into the cleaning column, and a driving mechanism is arranged on the left side of the cleaning box and drives the blade shaft to rotate. The upper ends of the blades are brushed through the steel brushes, meanwhile, the water outlet holes spray cleaning liquid to dissolve impurities, the lower ends of the blades extend into the water tank to be soaked and cleaned, impurity residues are reduced, the upper ends of the blades are brushed, the lower ends of the blades are soaked at the same time, the cleaning efficiency of the blades is improved, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of steam turbine equipment, in particular to a scaling cleaning device for steam turbine blades. Background technique [0002] The steam turbine, also known as the steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated air flow and then sprays onto the blades, so that the rotor equipped with blade rows rotates and works externally. Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plant. In the prior art, when the blades of the steam turbine receive steam, impurities such as scale will adhere to the surface of the blades. If cleaning is not performed regularly, the efficiency of the steam turbine will be affected. However, due to the huge size of the blades of the steam turbine in general large steam turbines, m...

Problems solved by technology

[0004] The object of the present invention is to provide a steam turbine blade fouling cleaning device. The upper end of the blade is scrubbed with a steel brush, and at the same time, the water outlet hole is sprayed with cleaning liquid to dissolve impurities. Simultaneous action of brushing the upper end of the blade and soaking the lower end, improving the cleaning efficiency of the blade, and solving the problem of low cleaning efficiency by flushing in the background technology
