Optical fiber laser double-rail cladding equipment for membrane water wall of high-parameter waste incineration boiler

Abstract

The invention provides optical fiber laser double-rail cladding equipment for a membrane water wall of a high-parameter waste incineration boiler. The optical fiber laser double-rail cladding equipment comprises a machine tool platform, sliding rails, robots, laser cladding heads and optical fibers; the machine tool platform is fixedly arranged on the horizontal plane, and one sliding rail is independently arranged along each of the side edges parallel to the two sides of the machine tool platform; the robots are fixedly arranged on the sliding rails, and after arms of the two robots stretch out to work, the cladding width between the robots is not smaller than 6 m; and laser cladding units are fixedly arranged at the tops of the robots, one ends inside the laser cladding units are connected with the optical fibers, and the laser cladding units comprise the optical fibers, laser light path adjusting modules and molten pool light path detecting modules. According to the equipment, a closed-loop control system is arranged, under the ultra-low heat input amount, the cladding layer thickness can reach 0.8 - 1.5 mm, the height is consistent, uniform and attractive, the powder utilization rate of laser cladding and the stable state of a molten pool are scientifically and reasonably controlled through adjustment, and a solid foundation is laid for large-scale and long-time unmanned operation.

Description

technical field [0001] The invention belongs to the field of optical fiber laser cladding equipment for water-cooled walls of boilers, in particular to fiber laser double-track cladding equipment for membrane-type water-cooled walls of high-parameter garbage incineration boilers. Background technique [0002] With the promotion of waste classification in major cities, the scale of waste incineration power generation is also expanding day by day. As the heat value of waste continues to increase and the parameters of the waste heat boiler increase from the conventional parameters (4.0Mpa, 400°C) to the high parameters (6.4Mpa, 450°C), due to the particularity of the fuel, the flue gas contains a large amount of acid gas and metals. compound. During the operation of the boiler, these harmful substances will corrode the boiler tube wall. Studies have shown that the corrosion rate of the metal tube wall of the boiler is proportional to the concentration of acid gas, metal compo...
