Problems solved by technology

If the concentration of nitrite is far below the standard, the oxygen content is also very low, and if the oxidation fan maintains a strong air volume, since the oxidation fan needs to consume a lot of power in the desulfurization system of the thermal power plant, it will cause huge damage. waste of electricity

Abstract

The embodiment of the invention discloses an air blower control method, equipment and system. The air blower control method, equipment and system are used for detecting the concentration of sulfite ina desulfurization reaction tank and determining the rotating speed of a variable frequency air blower according to the concentration of the sulfite. The air blower control method comprises the stepsof detecting the concentration of the sulfite in the desulfurization reaction tank; determining the rotating speed of the variable frequency air blower according to the concentration of the sulfite; and transmitting the rotating speed to the variable frequency air blower so that the variable frequency air blower can work based on the rotating speed. Due to the fact that the variable frequency airblower works based on the rotating speed, the rotating speed of the variable frequency air blower can dynamically meet work requirements without wasting excessive power consumption.

Description

technical field [0001] The present application relates to the field of desulfurization technology, in particular to a blower control method, equipment and system. Background technique [0002] In the power generation of thermal power plants, the combustion of coal will produce a large amount of exhaust gas containing sulfur and nitrate, which will cause pollution and form acid rain when discharged into the atmosphere. Desulfurization and denitrification equipment is required to treat these exhaust gases containing a large amount of sulfur and nitrate. Among them, the desulfurization process used by desulfurization equipment is mostly flue gas desulfurization, which is currently the most effective and widely used technology for controlling sulfur dioxide emissions in coal-fired power plants. [0003] In the process of flue gas desulfurization, calcium oxide is added to the exhaust gas of thermal power plants to make a chemical reaction with sulfur dioxide, so that calcium sul...
