The working principle of the invention is as follows: the metal ball in the transition box 11 is initially positioned on the conductive block 15 above the conveyor belt 14, at this time, the conductive block 15 is negatively charged, the charge amount is transmitted to the metal ball, repulsion force is generated between the metal ball and the conductive block 15, the metal ball moves to one side close to the air inlet block 12 along with the movement of the conveyor belt 14, the metal ball can slide upwards under the action of the guide inclined plane, the metal ball slides upwards and enters a uniform electric field area, the acting force of the uniform electric field on the metal ball is vertical upwards, the metal ball moves upwards in an accelerating way under the action of the uniform electric field, in the moving process, the smoke moves from the air inlet block 12 to the air outlet block 13, the smoke input in the air inlet block 12 contains more salt particles and fly ash, the metal ball moves to one side of the air outlet block 13 under the action of the smoke, in the process, the smoke and the metal ball are fully contacted, the impurity particles in the smoke are captured by the metal ball with static electricity, the weight is increased after the metal ball captures the impurities, when the action force of a uniform electric field is exceeded, the metal ball falls down to be separated from a uniform electric field area, the metal ball falls onto the conductive block 15 located above the conveying belt 14, more negative charges are attached to the conductive block 15, when the metal ball rolls along with the conveying belt 14, the surface of the metal ball is in contact with the conductive block 15, impurity particles are captured by the conductive block 15, the conductive block 15 drives the impurity particles to rotate, when the conductive block 15 rotates to the lower side of the conveying belt 14, the conductive block 15 is in contact with the contact block 17 connected with a ground wire, the charge quantity on the conductive block 15 is transferred away, and the impurity particles fall into the recovery tank 16. When the high temperature flue gas was divided during each first heating pipe 21, the waste heat of high temperature flue gas can heat the inside moisture of outer barrel 5, and heating pipe 31 can be according to waste gas waste heat temperature, adjusts the gas volume of input to guarantee that the boiler can last stable output steam.
