Intelligent optical observation and recognition system for flame-permeable wall surface of boiler

Abstract

The invention relates to the field of machinery, in particular to an observation system. An intelligent optical observation and recognition system for a flame-permeable wall surface of a boiler comprises an observation system body, the observation system body comprises an electric sliding rail, an observation device, a gas supply device and a control cabinet, the electric sliding rail comprises a sliding block, and the observation device is arranged below the sliding block; the observation device comprises an infrared camera and a camera protective cover, a hollow cavity is formed in the camera protective cover, and the infrared camera is arranged in the hollow cavity. Through cooperative work of the electric sliding rail, the observation device, the gas supply device and other components, real-time monitoring of the working condition in the boiler can be achieved, the safety of operators is improved, the boiler furnace area which cannot be observed by the operators originally can be observed, the observation area range is widened, the coking and slagging area can be recognized as soon as possible, and the safety of the operators is improved. Therefore, timely intervention of an operator is facilitated, and subsequent improvement of a soot blowing strategy is also facilitated.

Description

technical field [0001] The present invention relates to the field of machinery, in particular, to an observation system. Background technique [0002] Due to the form of coal supply and the need to reduce costs, many thermal power plants use coal types that deviate from the design coal types or use open-pit coal mine types that are prone to slagging and contamination. For example, the use of high-alkali coal causes serious coking and contamination of thermal power plant boilers; or, the coking and contamination caused by burning Indonesian coal. Coking and fouling of the boiler will affect the normal combustion conditions of the boiler, reduce the efficiency of the boiler, and affect the economy and safety of the boiler operation. and other means to reduce and alleviate the possibility of boiler contamination and coking. However, boiler coking and contamination cannot be avoided, and are still an important technical problem that threatens the safe operation of boilers. Aft...

AI Technical Summary

Problems solved by technology

Soot blowing after observing the contamination and coking of the heating surface tubes in the boiler is an important means to prevent serious coking in thermal power plants. This method mainly has high risks to personnel safety, limited observation area, and can only observe areas visible to the naked eye and bright positions
