The high-energy particles formed after acceleration and static electricity are input to the first-stage electric field electrode through the first-stage electric field power input line 40 of the purification device, the wiring clamping plate 85 and the wiring nut 86 (see figure 5), namely, the two power supplies are input to the first-stage electric field electrode after being connected in parallel.

The secondary electric field (see fig. 2) is provided by the power control cabinet 50 of the secondary electric field, the boost rectifier cabinet 51 of the secondary electric field and the secondary accelerator 54. The process of generating accelerated energetic particles and electrostatic power by the secondary electric field is similar to that of the primary electric field.

The power supply of the primary electric field and the power supply of the secondary electric field required by the purification device are respectively provided by a primary electric field power supply control cabinet 46 and a secondary electric field power supply control cabinet 50, the control cabinets have the functions of overcurrent and overvoltage, alarm and automatic power-off protection, when the output end is in short circuit, the impedance is infinite, the circuit voltage is zero, and the current is unchanged; the secondary coils of the boost rectifier cabinets 45 and 51 controlled by the control cabinet have two outputs, one is used as an accelerating power supply and is accelerated by an accelerator, and the other is used as an electrostatic power supply and is directly connected in parallel with the accelerated power supply and is simultaneously superposed on a corona electrode through a power supply input line.

Two valves are adopted, so that the smoke gas does not flow downwards and fly ash does not fly upwards. The operation process is as follows: the valve of the upper ash bucket and the rapping device are firstly opened to make the dust of the upper ash bucket fall into the lower ash bucket, and then the valve of the upper ash bucket is closed, and then the valve of the lower ash bucket and the rapping device are opened to put the dust into the ash transporting vehicle to be transported away, and then the valve of the lower ash bucket and the rapping device are closed, thus completing the whole ash discharging process.
