Examples

In the electrostatic type flue gas purifying device, the anode plate and the cathode plate are impacted by flue gas flow. And the thickness of the negative plate is thinner, such as a single negative plate is only 0.1mm, at the moment, the negative plate can shake under the impact of the flue gas, and in the shaking process of the negative plate, the electric field formed by the negative plate and the positive plate can become unstable, so that the flue gas purification efficiency of the flue gas purification device is reduced.

At this time, the strength of the cathode plate can be increased by thickening the cathode plate, so that the cathode plate can be always kept stable under the impact of flue gas. But the cathode plate needs to be increased in thickness when the strength of the cathode plate is raised only by the increase in thickness.

The present invention provides a clamping plate 100, the clamping plate 100 being used in assembly to form a cathode plate 10. Three configurations of the splint 100 are illustrated in fig. 1-3. The sidewall of the clamping plate 100 is bent to form a first bending portion 110. After the clamping plate 100 is bent to form the first bending portion 110, the bending strength of the clamping plate 100 becomes larger, and at this time, the clamping plate 100 can still be kept stable under the blowing of the air flow.

When two clamping plates 100 are symmetrically and fixedly connected back to form the cathode plate 10, the two first bending parts 110 are oppositely arranged, so that the bending resistance strength of the cathode plate 10 in the smoke flow direction is enhanced. Because the first bending part is arranged, the strength of the cathode plate 10 with the combined degree of the two clamping plates 100 is larger than that of the cathode plate 10 with the same thickness, and compared with the cathode plate 10 formed by combining the two clamping plates 100 in the application, the material is saved.

Further, the first bending portion 110 is provided with the spines 120, and the plurality of spines 120 facilitate the discharge of the cathode plate 10 formed by the clamping plates 100, so that the discharge electric field of the cathode plate 10 formed by the clamping plates 100 is more stable.

The clamping plate 100 may be any geometric shape adapted to the electric field, such as a polygon like a triangle, a quadrilateral or a pentagon. Or a curved surface shape such as a circle, an ellipse, etc. Or a combination of straight lines and curved lines, such as a semicircle.

Specifically, at least one first through hole 130 is further formed in the clamping plate 100, the first through hole 130 is disposed between the first bending portions 110, after the first through hole 130 is formed, the two clamping plates 100 are fixedly connected to form the cathode plate 10, and through holes are formed in the cathode plate 10, when the flue gas impacts the cathode plate 10, the flue gas can circulate from the first through hole 130, and impact of the flue gas on the clamping plates 100 (the cathode plate 10) is reduced.

The clamping plate 100 is bent along the side wall of the first through hole 130 to form a second bending part 140, and after the second bending part 140 is arranged, the strength of the clamping plate 100 is further increased, so that the cathode plate 10 can be kept stable under the blowing of the flue gas.

Further, the spike 120 is similarly provided on the second bending part 140, and the angles of the second bending part 140 and the first bending part 110 are the same. The second bending part 140 can also discharge through the spike 120 and stabilize the electric field.

After the two clamping plates 100 are fixedly connected back to form the cathode plate 10, as shown in fig. 4 and 8, when the cathode plate 10 and the anode plate 30 form an electrostatic field, the cathode plate 10 may be opposite to the two anode plates 30, if the angles of the first bending portion 110 and the second bending portion 140 are different, that is, the distances between the spines 120 on the first bending portion 110 and the second bending portion 140 and the respective opposite anode plates 30 are different, the electrostatic field formed by the spines 120 on the first bending portion 110 and one anode plate 30 will be different from the electrostatic field formed by the spines 120 on the second bending portion 140 and the other anode plate 30, so that the flue gas purifying efficiency is affected.

The bending angle is the angle between the first bending part 110 or the second bending part 140 and the upper plane of the clamping plate 100, that is, the first bending part 110 or the second bending part 140 is fixed at the position after being bent by the degree.

It can be understood that when the bending angles of the first bending part 110 and the second bending part 140 are the same, the bending directions of the first bending part 110 and the second bending part 140 are the same due to directionality at the angles.

At a bending angle of less than 30 °, the first bending portion 110 and/or the second bending portion 140 provide lower strength, and at a faster flue gas flow rate, the cathode plate 10 formed by the clamping plate 100 may shake.

When the bending angle is greater than or equal to 30 degrees, the cathode plate 10 consisting of the clamping plates 100 can be kept stable in the flue gas.

Due to the spatial fixation of the mounting cathode plate 10 and anode plate 30. When the bending angle is greater than 30 °, in the case where the distance between the spike 120 and the anode plate 30 is required to be maintained, the number of the cathode plate 10 and the anode plate 30 existing in the limited space is reduced, and at this time, the reduction in the number of the anode plates 30 for dust collection results in a reduction in the dust collection area of the purification apparatus, thereby reducing the purification efficiency.

Most preferably, the bending angle is set at 30 °, and the cathode plate 10 formed by the bending clamping plates 100 can not only meet the strength requirement, but also maintain as much dust collection area as possible.

To facilitate connection of the cathode plates 10 separated by the anode plates 30, second through-holes 150 are provided in the cathode plates 10. The shape of the second through hole 150 may be any shape, such as various polygons or curved polygons. It should be noted, however, that the strength of the cathode plate 10 composed of the clamping plates 100 should not be affected after the second through holes 150 are provided.

As shown in fig. 4 to 7, the present invention also discloses a cathode plate 10, which is composed of two clamping plates 100 symmetrically and fixedly connected, and the cathode plate 10 has all the advantages of the clamping plates 100.

The two clamping plates 100 are typically stapled together by a core back staple.

As shown in fig. 8-9, the invention also discloses a flue gas purifying device. The flue gas cleaning device comprises a first cleaning tank 20, an anode plate 30 and a cathode plate 10 as described above. The anode plate 30 and the cathode plate 10 are disposed in parallel and spaced apart in the first purge bin 20. The first purge bin 20 is provided with a first inlet 21 and a first outlet 22, and an electric field is formed between the anode plate 30 and the cathode plate 10 to adsorb smoke entering the first purge bin 20.

In order to make the smoke flow smoothly, at least one third through hole 31 is provided on the anode plate 30, and the number of the third through holes 31 corresponds to the number of the first through holes and is coaxially provided.

It should be noted that the opening of the third through hole 31 is larger than the second through hole 150, and the conductive wire connected to the adjacent cathode plate 30 through the second through hole 150 can not contact with the anode plate, so as to avoid leakage.

The anode plate 30 and the cathode plate 10 are provided in plurality, and one cathode plate 10 is opposite to one or two anode plates 30, so that an electric field can be formed between each cathode plate 10 and each anode plate 30, and the flue gas purifying efficiency is ensured.

In order to make the flue gas purification more complete, the flue gas purification device is typically also provided with a second purification tank 40, the second purification tank 40 being arranged downstream of the first purification tank 40. The second purge bin 40 is provided with a second inlet 41 and a second outlet 32, the second inlet 41 communicating with the first outlet 22. The second purifying box 40 is provided with a first cathode plate 43 and a first anode plate 44, wherein the first cathode plate 43 and the first anode plate 44 are flat plates (i.e. no spines are arranged on the first cathode plate 43 and the first anode plate 44), so as to reduce the production cost. Be provided with a first anode plate 44 between two adjacent first negative plates 43, and then can form the electric field between first negative plate 43 and the first anode plate 44, purify once more to the flue gas through first purifying box for the flue gas can be handled more cleanly.

The first purifying tank 20 is further provided with a mounting seat 23 for mounting an insulator. The mount pad 23 keeps away from the flue gas runner, and after the insulator is installed on mount pad 23, the insulator is at flue gas purification device during operation not with flue gas direct contact for the cleaning cycle extension of insulator.

It will be understood that equivalents and modifications will occur to those skilled in the art based on the present invention and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present invention.
