| titleOfInvention | Air particulate matter filter equipment |
| abstract | The invention discloses an air particulate matter filtering device which comprises a conductive filter screen device and a negative ion generating device, wherein the negative ion generating device is positioned at the upstream of the conductive filter screen device, the conductive filter screen device comprises a filter screen which is a conductive filter screen, and the air particulate matter filtering device also comprises an electrode metal plate which is arranged between the negative ion generating device and the conductive filter screen device and can be connected with a positive high-voltage power supply, and the positive high-voltage power supply voltage connected with the electrode metal plate is higher than the positive high-voltage power supply voltage connected with the filter screen. The negative ions generated by the negative ion probe are subjected to the traction force of the electrode metal plate, and the direction of the negative ions is opposite to the flowing direction of the gas, so that the contact time of the negative ions and microparticles in the air is prolonged; meanwhile, the voltage of the electrode metal plate is higher than the voltage connected to the conductive filter screen device, so that an electric field in the same direction as the wind speed is formed, the negative ions are forced in the electric field in the direction opposite to the wind speed, the contact time of the negative ions and micro-particles in the air is increased, the combination degree of the negative ions and the particles is improved, and the purification efficiency is improved. |
