Abstract
The invention relates to a recovery and treatment system of waste circuit boards, and especially an integrated system of recovery and resource treatment technology of waste circuit boards. The system comprises: a shear-mode breaking device, an impact-mode breaking device, a high-speed vortex crushing device, two high-efficient inner-container type winnowing devices, two high-voltage electrostaticseparation devices, a dust treatment device, a pulsed cloth-bag dusting device, and a ventilator, wherein the shear-mode breaking device, the impact-mode breaking device, the high-speed vortex crushing device, the two high-efficient inner-container type winnowing devices, the dust treatment device, the pulsed cloth-bag dusting device, and the ventilator are arranged in turn with one high-voltage electrostatic separation device communicated with one high-efficient inner-container type winnowing device and the other high-voltage electrostatic separation device communicated with the other high-efficient inner-container type winnowing device. The invention has the advantages of no secondary pollution, unique production, high efficiency, good recovery effect, low energy consumption, and long equipment service life, and truly realizes environmental-friendly, economical, and high-efficient resource treatment.
Description
Technical field: [0001] The invention relates to a recycling and processing system for waste circuit boards, in particular to an integrated system for recycling and resource processing technology for waste and old circuit boards. Background technique: [0002] Printed circuit board (PCB) is the foundation of the electronics industry. With the rapid development of the information industry, the production of printed circuit boards shows a trend of rapid growth. The average annual growth rate of the world's printed circuit board industry is 8.7%, of which China's growth rate is 14.4%. By 1995, the total output value of my country's printed circuit boards had accounted for 50% of the world's total output value of printed circuit boards. [0003] At present, China has become a major producer and consumer of home appliances and electronic products. Since 2003, my country has entered the peak period of household appliance elimination and scrapping. There are about 5 million refrig...
