The invention relates to an on-line method and equipment, aiming at providing a TRT (blast furnace top gas pressure recovery turbine unit) on-line energy efficiency analysis method and analysis meter. The method comprises the following steps of: collecting the operation data of a turbine unit by utilizing a sensor and transferring the operation data to an energy efficiency data calculating modulethrough a transmitter and a signal receiving and processing module, so as to obtain the energy efficiency data of the turbine unit; then transmitting the energy efficiency data to an energy efficiency filtering module to obtain the energy efficiency data after noise is removed; and transmitting the energy efficiency data after noise is removed to a display by a programmable controller. By using the method, the real-time data of the energy efficiency of the turbine unit can be obtained, and the operation management and optimization operation of the turbine unit are conveniently carried out; the collected operation parameters are processed, thus energy efficiency calculation data errors caused by noise which is brought by sampling can be effectively reduced; and the programmable controller and a touch screen are used as hardware platforms which have the characteristics of high reliability and low performance, so that history data can be stored and recorded for a long term.
Description
technical field [0001] The invention relates to an on-line energy efficiency analyzer for a turbine of a blast furnace gas waste heat recovery device. More specifically, it is an online calculation and analysis method and equipment for the energy efficiency of turbine operation in ironmaking blast furnaces. Background technique [0002] Blast Furnace Top Gas Pressure Recovery Turbine Unit (English Blast Furnace Top Gas Pressure Recovery TurbineUnit referred to as TRT device) is to make the pressure of blast furnace gas and A secondary energy recovery device that converts thermal energy into mechanical energy and then drives a generator. In the traditional blast furnace process, the blast furnace top gas (pressure 150-300kPa) is decompressed to about 10kPa through the pressure reducing valve group (or Bischoff dust collector) after dust removal, and then discharged into the gas storage tank for the factory hot blast furnace Used as fuel. The pressure energy and heat energy...
