Fiber laser dual-track cladding equipment for high-parameter waste incineration boiler membrane water wall

Abstract

The invention provides a high-parameter waste incineration boiler membrane-type water-cooled wall cladding equipment, including a machine tool platform, a slide rail, a robot, a laser cladding head, and an optical fiber; the machine tool platform is fixedly installed on a horizontal plane, along the A set of slide rails is independently installed on both sides and sides; the robot is fixedly installed on each set of slide rails, and after the two sets of robot arms are stretched out to work, the cladding width between the two sets is not less than 6m; laser melting The cladding unit is fixedly installed on the top of the robot, and one end inside is connected to the optical fiber. The laser cladding unit includes an optical fiber, a laser optical path adjustment module, and a molten pool optical path detection module. By setting the closed-loop control system and the ultra-low heat input, the equipment can realize the cladding layer thickness of 0.8-1.5mm, the height is uniform, uniform and beautiful, and the scientific and reasonable control of the powder utilization rate of laser cladding and the stable state of the molten pool can be adjusted. Large-scale, long-term unmanned operation has laid a solid foundation.

Description

technical field [0001] The invention belongs to the field of fiber laser cladding equipment for boiler water-cooled walls, and particularly relates to fiber-optic laser double-track cladding equipment for membrane-type water-cooled walls of high-parameter waste incineration boilers. Background technique [0002] With the promotion of waste classification in major cities, the scale of waste incineration power generation is also expanding. With the continuous improvement of the calorific value of the waste and the increase of the parameters of the waste heat boiler from conventional parameters (4.0Mpa, 400°C) to high parameters (6.4Mpa, 450°C), due to the particularity of the fuel, the flue gas contains a lot of acid gases 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 boiler metal tube wall is proportional to the concentration of acid gas in flue gas, the con...
