Abstract

PRECIPITADOR ELETROSTáTICO DO TIPO ELETRODO MOVENTE. A presente invenção refere-se a um precipitador eletrostático do tipo eletrodo movente capaz de reduzir a extensão de correntes sem fim mesmo que o coletor de partículas seja operado por um longo período e que aumenta o desempenho da coleta de partículas. Em um precipitador eletrostático do tipo eletrodo movente para capturar partículas em um gás em placas de eletrodo de coleta de partículas, por meio da descarga de efeito corona oriunda dos eletrodos de descarga, ao mover circularmente as correntes sem fim nas quais as placas de eletrodo de coleta de partículas estão suspensas, tal que as placas de eletrodo de coleta de partículas são circularmente movidas, a razão de ondulação de uma voltagem aplicada aos eletrodos de descarga é ajustada para 10% ou menos. Um gerador de alta freqúência a freqúência de radio, dotado de um comutador semicondutor, por exemplo, pode ser usado como uma unidade de fonte de alimentação para obter uma fonte de alimentação com corrente contínua a alta voltagem, tendo a razão de ondulação de 10% ou menos.ELECTROSTATIC MOVING TYPE PRECIPITATOR. The present invention relates to a moving electrode type electrostatic precipitator capable of reducing the extent of endless currents even if the particle collector is operated for a long period and which increases particle collection performance. In a moving electrode type precipitator to capture particles in a gas in particle collection electrode plates by discharging the corona effect from the discharge electrodes by circularly moving the endless currents in which the electrode plates are Particle collection is suspended such that the particle collection electrode plates are circularly moved, the ripple ratio of a voltage applied to the discharge electrodes is set to 10% or less. A high frequency radio frequency generator with a semiconductor switch, for example, can be used as a power supply unit to obtain a high voltage direct current power supply having a ripple ratio of 10%. or less.
