After the left movable polar plate 1161 and the right movable polar plate 1162 are jacked upwards by airflow to rotate mutually, the controller controls the electrifying time of the left movable polar plate 1161 and the right movable polar plate 1162, so that the included angle between the linear parts of the left movable polar plate 1161 and the left fixed polar plate 1172 can be fixed, and the included angle between the linear parts of the right movable polar plate 1162 and the right fixed polar plate 1172 is also fixed; the difference in this angle can produce different effects:
referring to fig. 11, for example, when the movable electrode plate and the fixed electrode plate are parallel to each other, air in the air can be uniformly ionized, and the effect of adsorbing fine dust particles or other fine particles is more uniform.
Referring to fig. 12, when the angle formed between the straight line portions of the movable plate and the fixed plate makes the left flow passage 1166 and the right flow passage 1167 become large and small, the average distance between the straight line portions of the movable plate and the fixed plate is the largest, and the ionization effect is the weakest; in addition, when the electrode plates enter the left flow passage 1166 and the right flow passage 1167, at a smaller inlet, the fine dust particles or other fine particles are charged quickly when the electrode plates are closer, and since the air flow velocity is faster at this position, the charged fine dust particles or other fine particles are not adsorbed or accumulated, but after passing through this position, due to the rapid increase of the space, an air flow expansion effect occurs when the electrode plates enter the left flow passage 1166 and the right flow passage 1167, the flow velocity of the air flow in the left flow passage 1166 and the right flow passage 1167 is reduced, the residence time of the charged fine dust particles or other fine particles is increased, and turbulence is formed in the left flow passage 1166 and the right flow passage 1167, so that the charged fine dust particles or other fine particles have a higher probability of moving to be adsorbed at the anode, although the ionization effect is not the best due to the angle between the moving electrode plate and the straight line portion of the fixed electrode plate and the average distance is increased, the adsorption effect of the charged fine dust particles or other fine particles by the anode in the left flow passage 1166 and the right flow passage 1167 can be increased, and thus the adsorption effect is not reduced too much.
Referring to fig. 13, when the angle formed between the straight portions of the movable plate and the fixed plate makes the left flow passage 1166 and the right flow passage 1167 smaller from top to bottom, the distance between the straight portions of the movable plate and the fixed plate gradually decreases from bottom to top, and the average distance between the straight portions of the movable plate and the fixed plate is the smallest, so that the ionization effect is the strongest, and the ionization capacity thereof gradually increases from bottom to top, so that the fine dust particles or other fine particles that are more easily adsorbed are adsorbed first, and the fine dust particles or other fine particles that are less easily adsorbed are then adsorbed, so that the adsorption of the fine dust particles or other fine particles is more dispersed, and thus the adsorption capacity of the anode can be better extended.
The air purification quality can be remarkably improved by combining the preset voltage intensity under the data of the total electrostatic parameters in the switch cabinet shell 1 and the dust concentration of the outside air and adjusting the angle between the two movable polar plates to ensure that the two movable polar plates conform to the preset optimal solutions of different electrostatic parameters and parameters under the dust concentration; the optimal balance between static neutralization capacity and energy conservation and environmental protection can be determined by only carrying out a large number of tests in a laboratory, and the optimal solution is pre-loaded into an equipment system.
In addition, referring to fig. 6, an inverted U-shaped elastic electrode plate 1168 can be connected above the pyramid structure 116, two sides of the elastic electrode plate 1168 are respectively connected to the top ends of the two movable electrode plates, and the connection is isolated by using an insulating material, and there is a smooth transition between the movable electrode plate and the elastic electrode plate 1168; the elastic electrode plate 1168 is an anode; the elastic electrode plate 1168 can deform along with the angle change of the two movable electrode plates. The elastic electrode plate 1168 mainly has the following functions: firstly, the coanda effect is utilized to enable the airflow flowing out of the left flow channel 1166 and the right flow channel 257 to be attached to the elastic electrode plate 1168 to flow, so that the adsorption effect on charged impurities and harmful molecules is better; secondly, in the back washing process, the fan rotates reversely, the elastic electrode plate 1168 guides the airflow from top to bottom to enter from the left flow channel 1166 and the right flow channel 257, and the resistance of the airflow is reduced; thirdly, the two movable polar plates are applied with external supporting force and have the tendency of unfolding in the power-off state by matching with the gravity of the electrorheological body, and it should be noted that the foldable surface 1163 should limit the movable polar plates from touching the fixed polar plates when the two movable polar plates are unfolded in the power-off state.
Arc-shaped flow baffles 1169 are respectively arranged at the outer ends of the two flow channels, the middle parts of the arc-shaped flow baffles 1169 are sunken outwards to block and guide the air flow to one side of the elastic electrode plate 1168, and the two arc-shaped flow baffles 1169 are distributed like brackets; the arc flow baffle 1169 is also connected to the top ends of the two fixed pole plates, the connection is isolated by insulating material, and the arc flow baffle 1169 is also an anode and can absorb fine dust particles or other fine particles.
In addition, referring to fig. 10, the counter-washing process utilizes bernoulli effect to realize the counter-washing and the expansion washing through the change of the diameter of the flow channel; secondly, the fine dust particles or other fine particles can be detached from or not attached to the plate by changing the polarity of all the plates or frequently changing the polarity of all the plates, thereby playing a role in cleaning.
The controller automatically receives the electrostatic parameters detected by the electrostatic sensor arranged in the cabinet body 1 and the dust and metal particle concentration detected by the outdoor air detector at intervals, compares the parameters with a prestored database, and calls the control parameters in the corresponding range,
if the control parameters require that the two movable polar plates rotate upwards relative to the current state, the controller controls each polar plate to be powered off, the current variant in the pyramid structure 116 is restored to be liquid state, the two movable polar plates continue to rotate upwards under the action of wind pressure, the controller determines that the current of each polar plate is switched on again when the two movable polar plates rotate to the required angle through the micro angle sensor, the current variant is restored to be solid state again under the electric field of the two movable polar plates, and the angles of the two movable polar plates are fixed; and then the controller adjusts the voltage of each electrode plate according to the control parameters, and the rotating speed of the fan reaches the parameter requirement.
If the control parameters need the two movable electrode plates to rotate downwards relative to the current state, the controller controls each electrode plate to be powered off, the current variant in the pyramid structure 116 returns to the liquid state, then the controller controls the fan to stop or reduce the rotating speed, the two electrode plates rotate downwards under the condition that no wind pressure or wind pressure is smaller than the gravity of the current variant and the driving force of the elastic electrode plate 1168 for the downward rotation of the two electrode plates, the controller determines through the micro angle sensor that when the two electrode plates rotate to the required angle, the current of each electrode plate is switched on again, under the electric field of the two movable electrode plates, the current variant returns to the solid state again, and the angle of the two movable electrode plates is fixed; and then the controller adjusts the voltage of each electrode plate according to the control parameters, and the rotating speed of the fan reaches the parameter requirement. The above actions and changes all occur instantaneously, and therefore, the time taken for the above regulation and control process is extremely short and hardly noticeable.

In this respect, the device realizes the consideration; II, performing secondary filtration; first, static electricity adsorbs dust, and insulation resistance of components is reduced (service life is shortened). Second, electrostatic discharge (ESD) damage causes the electrical device to fail to operate. Thirdly, the electromagnetic field generated by electrostatic discharge has large amplitude (hundreds of volts/meter) and extremely wide frequency spectrum (from tens of mega to thousands of mega), and causes interference and even damage to electrical equipment (electromagnetic interference); the current electric equipment has static electricity and corrosion phenomena in application, and the rights and interests of power utilization units are seriously influenced.
