Description
Technical field
This utility model relates to a kind of flue gas FGD oxidation fan energy-saving control system.
Background technology
Desulphurization system energy-saving run increasingly comes into one's own, and in order to meet environmental requirement, a lot of enterprises desulphurization system has be carried out or face carrying out minimum discharge transformation, further increases the desulphurizing ability of system.During desulphurization system is run, power consumption cost accounts for totle drilling cost about about 40%, and in flue gas desulphurization system, oxidation fan is generally adopted multiple stage redundant configuration mode, and at present without having effective means and means, as long as namely desulphurization system puts into operation, oxidation fan must be exerted oneself, and exerts oneself 100%.Current power plant load changes greatly, and coal-fired sulfur is relatively low, and under such premise, the oxidation fan as the main current consuming apparatus of desulfurization still adopts most basic configuration, without any runing adjustment means.So cause substantial amounts of waste of energy, add unnecessary production cost.
Utility model content
In order to solve the problems referred to above, the utility model proposes a kind of flue gas FGD oxidation fan energy-saving control system, adjustments of exerting oneself that this system is capable of under different load and ature of coal oxidation fan, to reduce the purpose of operation power consumption.
