Abstract

The invention discloses a coking and slagging robot processing system for a high-temperature hearth of a coal fired power plant boiler. A robot body is externally and sequentially provided with an insulation layer, an inner wall, a cooling water interlayer and an outer wall from internal to outside, wherein a short-range nozzle and a long-range nozzle are arranged on the outer wall; the front part of a main CCD (Charge Coupled Device) camera is provided with a high-temperature resistant anti-reflection LOW-E membrane, and the rear part of the main CCD camera is provided with a cooling fan; an inner high-temperature resistant insulation layer, an outer high-temperature resistant insulation layer and a middle vacuum thermal-protective layer are arranged in a visualized imaging system, an inner layer of the inner high-temperature resistant insulation layer is provided with an air forced convection cooling structure, and an outer layer of the outer high-temperature resistant insulation layer is a glass LOW-E membrane coating. The coking and slagging robot processing system can normally operate in a flow field at a temperature ranging from normal temperature to 1200 DEG C, can visually reflect depositing and slagging conditions of the power plant boiler at any time, can also be used for processing the depositing, coking and slagging conditions, can effectively prevent accidents of tube explosion and the like, and can effectively avoid abnormal working conditions such as heat deviation, unstable hydrodynamic force, pulsation among pipes, water circulation stagnation and water backflow, and the like caused by uneven heating of a heat exchanging surface due to depositing, coking and slagging.

Description

technical field [0001] The invention relates to the fields of heat transfer, optics, mechanical design and manufacture, and signal transmission. It is an inventive device with simple operation, small space occupation, convenient control, strong reliability and high economic value. Background technique [0002] Coking, slagging treatment equipment and visual imaging equipment currently on the market are basically unable to work in a high-temperature flow field of 1200 °C. The main reason is that the combustion environment of the power station boiler furnace is harsh, and the combustion temperature is too high, which can easily cause equipment wear and melting, resulting in damage to the imaging equipment. According to the working characteristics of the high-temperature flow field, the invention adopts the outer protective layer, the inner vacuum insulation layer of the outer thermal insulation layer, and forced air cooling measures to ensure that the working temperature of t...
