Intelligent auxiliary system for coal conveying belt operation of thermal power plant

Abstract

The invention discloses an intelligent auxiliary system for coal conveying belt operation of a thermal power plant. The intelligent auxiliary system comprises the components of a three-fluid spraying dust suppression system which mixes an agent with a dust suppression function and water for obtaining a soup mixture, crushes the soup mixture for obtaining spray particles by means of gas and sprays out the spray particles through a nozzle; a coal conveying belt fire early-warning system which acquires a thermal infrared image of the coal conveying belt in real time, wherein the thermal infrared image is acquired by a thermal infrared image acquisition device, calculates a temperature value in the thermal infrared image, and generates an early-warning signal on the condition that the temperature value in the thermal infrared image exceeds a preset threshold; a factory-grade central control system which receives data of the three-fluid spraying dust suppression system and the coal conveying belt fire early-warning system, and performs central control on the three-fluid spraying dust suppression system and the coal conveying belt fire early-warning system; and a cloud data monitoring system which receives data of the factory-grade central control system and performs cloud storage data analysis. The system of the invention realizes central control and facilitates management on each auxiliary sub-system of the thermal power plant.

Description

technical field [0001] The invention relates to the technical field of intelligentization of a thermal power plant, in particular to an intelligent auxiliary system for running a coal conveying belt in a thermal power plant. Background technique [0002] At present, the technology in the field of thermal power plants in my country has developed rapidly. The capacity of unit units has grown from 300MW to 600MW, and the capacity of unit units in Waigaoqiao Power Plant has reached 900MW. The successful application of DCS system in thermal power stations has greatly improved the level of automation investment in the field of power station control. However, the control system of the thermal power plant still stays in the control of the thermal power generating set. [0003] With the rapid development of thermal power generation technology, various auxiliary subsystems have emerged one after another for auxiliary functions of thermal power generation, such as monitoring, early wa...

Problems solved by technology

However, in the existing technology, the development of auxiliary subsystems still stays in the independent work of each auxiliary subsystem, which makes the management of each auxiliary subsystem in thermal power plants extremely cumbersome.
