Pulse Discharge Desulfurization Reactor Electric Parameter Measurement And Structural Optimization

In this paper, detailed studies were made on discharge characteristics of pulse corona reactor, the influences of electrode configuration on desulfurization and pulse energy transmission along the discharge wires for industrial application of the technique. The following results were obtained.1. The influence factors (such as voltage, pulse forming capacitance, wire-to-plate spacing, wire-to-wire spacing) on discharge characteristics are researched on the condition of room temperature and air medium, and the discharge characteristics of reactor are obtained: the peak value, minimum value and wave tail of pulse voltage firstly increase with the increase of wire-to-wire spacing, then all decrease; but pulse energy firstly decreases with the increase of wire-to-wire spacing, then increases. According to experimental conclusion, the experimental formula of the optimized electrode configuration, b=0.3c+37.5 (b, wire-to-wire spacing; c, wire-to-plate spacing) is gotten.2. The attenuation and distortion law of pulse voltage transmitting on discharge electrode is obtained by research of energy attenuation on different conditions (such as voltage, terminal matching and diameter). Pulse voltage sharply decreases due to the corona. The higher the pulse voltage, the thinner the diameter of the wire, then the more seriously the pulse voltage attenuates; the tail of the corona wire is more influenced by the reverberation. The sharp attenuation of the corona along the wire has to be considered in designing a real reactor for getting higher reacting efficiency and the length of wire should be no more than 1 Om.3. On the basis of above-mentioned experimental conclusions, an experimental desulfurization system with the flux of 200Nm3/h is optimized, and preferable efficiency of desulfurization is obtained.
