Abstract

The invention discloses a temperature field real-time monitoring device of an air-cooled condenser. The device comprises the following components: a collection device for collecting the temperature of the heat exchange tube wall at the air outlet position of each tube bundle; a controller connected to the signal of the collection device The output port is used to obtain the steam temperature in the corresponding tube bundle according to the temperature signal of the wall surface of the air outlet, and display the steam temperature in each tube on the interface of the display device; the display device displays the steam temperature in the tube of each tube bundle on the interface; Compared with the condensed water temperature at the outlet of the air-cooled condenser, this paper directly collects the wall temperature of the air outlet of each tube bundle of the air-cooled condenser, which greatly improves the accuracy of judging the temperature inside the tube bundle and reduces the temperature blind area. The monitoring of the internal temperature of the tube bundles and even the flat tubes is helpful for the staff to keep abreast of the working conditions of each tube bundle or flat tubes, avoid local overcooling of the air-cooled condenser, and further improve the reliability of the air-cooled condenser and improve the power generation efficiency of the power plant.

Description

technical field [0001] The invention relates to the technical field of temperature control of an air-cooled condenser tube bundle, in particular to a real-time monitoring device for a temperature field of an air-cooled condenser. Background technique [0002] In Northeast my country, North China, and Northwest China, coal resources are relatively rich, but water resources are very scarce. The use of air-cooled systems can save more than 90% of water resources per year compared with wet-cooled systems. Among them, the operation of air cooling equipment is directly related to the safety and economy of power plant operation. [0003] At present, air-cooled power generation technology is widely used in the field of power generation because it can better solve the problem of water shortage in power generation. Among them, the air-cooled condenser is one of the key equipment to realize air-cooled power generation. The air-cooled condenser mainly includes steam distribution pipes...
