Problems solved by technology

However, the traditional soot blowing system cannot accurately monitor the ash deposit and slagging, so it can only use a regular and quantitative blowing method, which is blind and causes a lot of loss

Abstract

The invention relates to an intelligent soot blowing method and an intelligent soot blowing system based on three-dimensional reconstruction of images. The method comprises the following steps: S1: monitoring a heating surface and obtaining the two-dimensional image of the heating surface; S2: carrying out three-dimensional reconstruction on the two-dimensional image to obtain the three-dimensional image information of the heating surface; S3: carrying out fuzzy processing on the three-dimensional image information to obtain a corresponding control instruction; and S4: starting or stopping or maintaining soot blowing operation for the heating surface according to the control construction. According to the invention, online monitoring on overall soot formation and slagging of the heating surface of a boiler is combined with fuzzy control, and therefore, online monitoring on the overall heating surface of the boiler is achieved, and soot blowing is carried out on local heating surface according to requirements, thus effectively optimizing soot blowing, reducing soot blowing duration, reducing soot blowing energy consumption and improving the overall heat efficiency of the boiler.

Description

technical field [0001] The invention relates to the technical field of intelligent soot blowing of coal-fired boilers, in particular to an intelligent soot blowing method and system based on three-dimensional image reconstruction. Background technique [0002] During the operation of coal-fired boilers, the accumulation of dust and slagging on the heating surface is a long-standing problem. Due to the large thermal resistance of ash and slag, the accumulation of ash and slagging on the heating surface of the boiler will not only reduce the thermal efficiency of the heating surface, but also cause the surface temperature of the heating surface to be too high, resulting in super-temperature and high-temperature corrosion of the metal on the heating surface, and even the explosion of the furnace tube. leak. On the other hand, the reduced efficiency of the heating surface will increase the coal consumption of the unit, increase the temperature of the furnace outlet and the fina...
