The invention discloses a carbon fiber dust collecting electrode plate type static air cleaning device and belongs to the technical field of cleaning equipment. The carbon fiber dust collecting electrode plate type static air cleaning device is formed by a discharge area and a dust collecting area; the discharge area is formed by front ends of a set of carbon fiber dust collecting plates and discharge pins or sharp spines which are arranged before metal plates; the dust collecting area is formed by carbon fiber panels and metal panels which are arranged in a staggered mode; the carbon fiber plates are used for collecting dust; the metal plates are used for forming into electric field. According to an air cleaning method, at the front end of the device, the discharge area generates into high voltage static to enable particulate matters in the air to be ionized and microorganism is effectively killed; when the air arrives at the dust collecting area, electric field force which is formed between carbon fiber negative electrode dust collecting plates and metal plate positive electrode plates is used for absorbing ionized particulate matters. The carbon fiber plates have the advantages of being good in specific surface area, having a good absorption effect and a high structural strength, being corrosion resistant and the like. Compared with the existing dust removing device, the carbon fiber dust collecting electrode plate type static air cleaning device has the advantages of being simple in structure, high in dust removing effect, small in wind resistance, long in washing period and good in washing effect.
