Abstract

The invention discloses an antifreeze system and method for online monitoring of the inlet air temperature of the whole sector of an indirect air cooling tower. The method of online monitoring of the inlet air temperature of the whole sector of an indirect air cooling tower is used to obtain the real-time temperature distribution diagram of the finned tube of the whole sector and the inlet air temperature. And circulating water temperature, enter the expert system for online analysis, realize the function of providing real-time antifreeze strategy for the indirect cooling tower, improve the economy of the unit in winter operation and effectively solve the antifreeze problem of the indirect cooling tower.

Description

technical field [0001] The invention belongs to the technical field of energy saving and consumption reduction of coal-fired units, and in particular relates to an antifreeze system and method for online monitoring of the inlet air temperature of the whole sector of an intercooling tower. Background technique [0002] Since most of the intercooling units are built in the northern low temperature area, the external ambient temperature is low, and some units will also participate in winter heating or industrial steam supply, and the extracted steam will enter the heating network heater or be used for external steam supply. The heat load of the cooling equipment is often lower than the minimum antifreeze amount of the air-cooled unit, and the antifreeze pressure of the air-cooled equipment is huge. Under extreme conditions, when the low-pressure cylinder runs with zero output or micro-output, the heat load entering the air-cooling tower is only 1 / 30 or even less of the design v...
