Examples

The electrostatic dust collector has excellent flue gas cleaning effect, and is widely applied to various flue gas cleaning fields, such as kitchen range hoods, industrial tail gas cleaning devices and other scenes in which particles in flue gas need to be treated.

The electrostatic field is generally used for adsorbing particles and is generally composed of a cathode plate and an anode plate which are arranged on different screws at intervals, wherein the cathode plate and the anode plate are oppositely arranged, when the cathode plate discharges, an electric field is formed between the cathode plate and the anode plate, and particles carried in flue gas passing through the middle of the cathode plate and the anode plate move towards the anode plate under the action of the electric field and are adsorbed by the anode plate.

When treating a large flow of flue gas containing particles, an anode plate having a larger dust collection area (an area of the anode plate for adsorbing particulate matters) is generally selected, and in general, a technician increases the dust collection area by increasing the number of anode plates. On the basis of the increase in the number of anode plates, the number of cathode plates is also required to be increased.

Because the negative plate is suspended through the supporting rods and arranged between the positive plates, after the number of the negative plates is increased, the original supporting rods cannot bear the heavy pressure of the negative plates, and at the moment, the supporting rods can bend and deform under the action of the gravity of the negative plates, so that the negative plates fixed on the supporting rods are not vertical any more, the polar distance of an electrostatic field (the distance between the negative plates and the positive plates) is changed, the electrostatic field discharge is abnormal, and the flue gas purifying effect is poor.

The utility model discloses a large electrostatic field, wherein a weight-bearing rod 70 is fixedly connected between two cathode frames 40, and all cathode plates 60 are borne by the thicker weight-bearing rod 70, so that the load of a second supporting rod 50 is reduced, the deformation of the second supporting rod 50 is avoided, the polar distance of the electrostatic field is ensured to be kept in a proper range, and the electrostatic field maintains the purifying effect on flue gas.

Specifically, referring to fig. 1 and 2, the large electrostatic field disclosed in the present utility model includes two opposite side brackets 10, a plurality of first struts 20 are disposed between the two side brackets 10, and two ends of the first struts 20 are fixedly connected with the two side brackets 10 respectively. A plurality of anode plates 30 are fixed on the first support rod 20, and the anode plates 30 are arranged between the two side brackets 10 at intervals. The two side brackets 10 are provided with cathode brackets 40 at the sides far away from the anode plate 30, the cathode brackets 40 are provided with two, and the cathode brackets 40 are connected with the side brackets 10 in an insulating way. A second support bar 50 is arranged between the two cathode frames 40, two ends of the second support bar 50 respectively penetrate through the two side brackets 10, two ends of the second support bar 50 are respectively fixedly connected with the two cathode frames 40, and the second support bar 50 is not connected with the side brackets 10. As shown in fig. 3, a plurality of cathode plates 60 are fixed on the second support bar 50, the cathode plates 60 are arranged between the two side brackets 10 at intervals, each cathode plate 60 is arranged between two adjacent anode plates 30, namely, the left side and the right side of each cathode plate 60 are anode plates 30, and flue gas passes through the gaps between the cathode plates 60 and the anode plates 30 from the arrow direction shown in fig. 1, and is further purified by an electric field between the cathode plates 60 and the anode plates 30.

Referring to fig. 1 and 4, two cathode holders 40 are fixed in the same manner as the side holders 10.

A weight-bearing rod 70 is further arranged between the two cathode frames 40, two ends of the weight-bearing rod 70 are fixedly connected with the two cathode frames 40 respectively, the weight-bearing rod 70 penetrates through the cathode plate 60 and the anode plate 30, the weight-bearing rod 70 is fixedly connected with the cathode plate 60, the weight-bearing rod 70 is not connected with the anode plate 30, and the weight-bearing rod 70 is used for bearing the cathode plate 60. After weight bar 70 is positioned, all of the weight force exerted by cathode plate 60 falls onto weight bar 70, at which point second struts 50 are no longer under force. Because the weight-bearing rod 70 is a thicker tube, the weight-bearing rod cannot deform under the action of gravity of the cathode plate 60, and the polar distance of the electrostatic field is stable on the basis that the weight-bearing rod 70 and the second supporting rod 50 cannot deform, so that the electrostatic field can keep a good flue gas purifying effect.

It should be noted that the connection relationship of the side bracket 10 on the other side in fig. 1 to the cathode bracket 40 not shown is the same as the connection relationship of the cathode bracket 40 to the side bracket 10 shown.

Further, referring to fig. 2 and 6, the bogie 70 is disposed on the gravity center line of the cathode plate 60, so that after the cathode plate 60 is supported by the bogie 70 to be stable, the gravity direction of the cathode plate 60 is collected on the bogie 70, and the cathode plate 60 is not inclined or offset in the process of being supported by the bogie 70, so as to ensure the stability of the electrostatic field.

Likewise, to ensure that the cathode plate 60 discharges to the anode plate 30, the area of the gap is not too large to be set in order that the first struts 20 and the cathode plate 60 are not electrically connected.

The third relief 11 may be circular, square, oval or other shaped aperture. Of course, care should be taken when drilling holes into side bracket 10 so that side bracket 10 is not electrically connected to second strut 50 or weight-bearing bar 70.

Specifically, first and second struts 20, 50 and weight-bearing rod 70 may be round, square, or other tubes. In one embodiment of the present utility model, to facilitate the opening of the cathode plate 60, the anode plate 30, the side brackets 10 and the cathode frame 40, the first support bar 20, the second support bar 50 and the weight-bearing bar 70 are round tubes.

Angle iron is generally selected for angle iron 80, and the angle iron in the shape of L surrounds anode plate 30, so that anode plate 30 is abutted against the angle iron, and anode plate 30 can be well supported. After the corner protector 80 is welded with the side brackets 10, an integral body is formed between the two side brackets 10 and the corner protector 80.

More specifically, referring to fig. 5, the electrostatic field further includes an insulator 90, one end of the insulator 90 is fixedly connected to the cathode holder 40, and the other end is fixedly connected to the side bracket 10, thereby enabling the cathode holder 40 to be electrically connected to the side bracket 10. Of course, the insulator 90 merely insulates between the cathode frame 40 and the side frame 10, and is an insulator commonly used by those skilled in the art. The insulator 90 may be replaced with other products having the same effect.

Of course, in order to fix the first and second support rods 20, 50 or the weight-bearing rod 70, threads are provided at both ends of the first and second support rods 20, 50 and the weight-bearing rod 70, and the first and second support rods 20, 50 and the weight-bearing rod 70 can be fixed to the side brackets 10 and the cathode frame 40 by nuts.
