A carbon separation and collection device used for a high performance dust collector includes a water supply tube, a water pump, a high pressure negative electrode discharge device, a high pressure positive electrode discharge device, a rotary brush, a removing plate, a carbon collector, a liquid tank, and a speed change device and an exhausting tube. The two discharge devices serve to achieve a function of electrolyte. When the cleaning liquid with carbon flows into the water supply tube by using the water pump. The carbon is adhered to the high pressure positive electrode discharge device. The high pressure positive electrode discharge device is driven to rotate by the speed change device. The carbon is moved from the high pressure positive electrode discharge device by the rotary brush and removing plate. Then, the removing carbon drops into the carbon collector.
