Description

technical field

[0001] The invention relates to a nozzle used for a flue gas desulfurization device of a large coal-fired unit in a thermal power plant, namely a low-resistance swirl liquid column nozzle. Background technique

[0002] China's large-scale coal-fired boiler flue gas desulfurization technology has experienced a tortuous development process from scratch. The country has almost brought together various international excellent desulfurization technologies, but my country still lacks commercial desulfurization technologies suitable for my country's national conditions, especially in my country. It is not yet fully capable of designing and manufacturing flue gas desulfurization devices for coal-fired units in large thermal power plants. Contents of the invention

[0003] The purpose of the present invention is to provide a nozzle suitable for the flue gas characteristics of a large coal-fired unit in a thermal power plant for a high-efficiency pipeline reaction des...
