Problems solved by technology
[0003] The existing air-cooling temperature field online monitoring technology mainly adopts the form of wireless temperature sensor, or temperature sensor + bus cable, and the data transmission front-end device and bus control cable upload the temperature data to the host computer or enter the DCS to complete the entire intercooling unit unit. real-time temperature detection, through the analysis and processing of real-time temperature data by the host computer or DCS software, and alarm; It is not suitable for large-scale, long-distance transmission and other issues, and the inability to accurately monitor the temperature will affect the safety of the steel structure smoke tower, causing hidden dangers in the production work of the power plant
At the same time, the temperature monitoring system is only used for monitoring and alarming, and is not included in the control system

The invention discloses an intelligent monitoring system for the temperature field of chimney and cooling tower integrated steel structure indirect air cooling tower. The system involves a grating temperature measuring sensor, a grating adjusting instrument, a signal switch, a control system and shutters. The temperature of a steel structure smoke tower is monitored through the grating temperaturemeasuring sensor, the temperature data are converted into an electric signal through the grating adjusting instrument to be transmitted to a monitoring platform through the signal switch, the monitoring platform realizes in-time monitor, and a power plant DCS system controls the opening degree of the shutters, so that the temperature of the smoke tower is controlled, the remote temperature monitor and control is realized, the monitor is accurate, the reliability is high, the safety stability is achieved, and the safe operation of a power plant is guaranteed.
Description
Technical field [0001] The invention relates to a temperature monitoring system, in particular to an intelligent monitoring system for the temperature field of a cooling tower between a smoke tower and a steel structure. Background technique [0002] As an important link in the electricity production process of coal-fired power plants, the indirect cooling tower plays a key role in energy saving and emission reduction. The reasonable operation of the indirect cooling system, comprehensive monitoring of the operating parameters of the indirect cooling tower, accurate analysis, efficient processing, and realization of intelligent control are extremely important for the normal operation of the power plant, as well as energy saving and emission reduction. The steel structure cooling tower with integrated smoke tower is an innovative structural system in the air cooling system. It has the characteristics of green environmental protection, high efficiency and energy saving, but it has ...
