Example 1, unchanged at the dust remover volume, heteropolar interval is unchangeable, experiment B and experiment C discharge needle group district are 3 row needle structures, under flue gas volume and entry concentration all unchangeable condition, adopt current dust remover structure through experiment A, utilize the soft steady power of single output high frequency to test, experiment B adopts novel environmental protection electrostatic precipitator technique, utilize the soft steady power of single output high frequency to test, experiment C adopts novel environmental protection electrostatic precipitator technique, utilize the high frequency power of dual output to test, the contrast of experimental data reachs:

1. comparing the experimental data of experiment A and experiment B to obtain: the experiment is also carried out by using a single-output high-frequency soft and stable power supply, a novel environment-friendly electrostatic dust collector technology is adopted, and a discharge and dust collection integrated polar plate and a brush roller are used for dust collection, so that the discharge effect of the experiment B is better than that of the experiment A;

2. the comparison of experimental data of experiment A, experiment B and experiment C shows that: adopt novel environmental protection electrostatic precipitator technique, use integrative polar plate of discharging and gathering dust, brush roller dust removal and the soft steady power of dual output high frequency, it tests C's emission effect and is better than experiment A and experiment B's emission effect.

The novel environment-friendly electrostatic dust collector technology is compared with the prior traditional dust collector technology to learn that:

the discharge and dust collection integrated polar plate is used, under the conditions that the volume of the dust collector is unchanged and the distance between different poles is unchanged, the distance between the different poles of the dust collector structure in the experiment A is 220mm, and the dust collector structure consists of the dust collection polar plate and a barbed wire without the polar plate; the dust collector in experiments B and C has a heteropolar spacing of 220mm, and consists of a dust collecting polar plate and a dust collecting polar plate, and compared with experiment A, the dust collecting area is increased by using the discharge and dust collecting integrated polar plate.

When the double-output high-frequency soft stable power supply is used, the positive high-voltage discharge needles discharge to the dust collecting area of the negative high-voltage polar plate, the negative high-voltage discharge needles discharge to the dust collecting area of the positive high-voltage polar plate, and opposite attraction forms two polar plates to collect dust. The dust adsorbed on the polar plate can not easily fall down. Meanwhile, because the positive and negative polar plates are dust collecting electrodes and discharge electrodes, the charges of the dust-collecting part deposited on the dust collecting polar plates and the discharge needle group discharge to the corresponding polar plate dust collecting areas together, thereby avoiding the accumulation of overhigh charges in the dust layer and eliminating the generation of the back corona phenomenon. The positive and negative outputs of the double-output high-frequency soft stable power supply are high voltages and are connected with the positive and negative electrodes of the discharging and dust collecting integrated polar plate, and the shell of the dust collector is grounded. The potential difference is from positive high potential to negative high potential and then to zero potential, and the discharge electrode and the dust collecting electrode are generated between the high potential and the high potential electrode plate. Large charge amount and strong electric field intensity. The charged particles are the movement process from the strong electric field of the discharge electrode to the strong electric field of the dust collecting electrode. Can effectively adsorb ultrafine dust and improve dust collection efficiency.

The use of the brush roller dust removal assembly can firstly effectively remove deposited particles which are not easy to fall and are adsorbed on the polar plate, the brush roller brushes dust up and down, secondary dust raising caused by vibration is avoided, the insulator, the dust collection polar plate and the discharge needle are kept clean by brushing the brush up and down, and an electric field is always in an optimal running state; avoiding the deformation of the interior of the dust collector caused by rapping.

The dust collection quantity is improved and the aims of high-efficiency dust collection are fulfilled completely through the use of the double-output high-frequency soft and stable power supply, the discharge dust collection integrated polar plate and the brush roller dust collection assembly.
