Energy-saving transformation of high-voltage Inverter in sulphuric acid production system
XU Yanfei;Guangdong Yunfu Lianfa Chemical Co.,Ltd.;
Analysis of the impact of the power loss of the high-voltage fan of the sulphuric acid plant and the deficiencies of speed control of hydraulic coupler of the original use,proposed high-voltage inverter transformation of fan speed control.Without changing the original equipment structure and layout of the case,an increase of high-voltage frequency control and power switching control functions,both to protect the process control flexibility and continuity of regulation,but also can maximize the motor to achieve a variety of operational protection And production of energy-saving control,the transformation effect is very significant.
