Abstract
Description
Technical Field
[0001] This application relates to the field of power pulse generator technology, and in particular to a high-voltage pulse power pulse generator for electrostatic precipitators. Background Technology
[0002] In the field of electrostatic precipitators, the power supply is one of the key factors affecting their dust removal efficiency. Pulse power supply technology is an important method for powering electrostatic precipitators. It utilizes the principle that electric field flashover requires a certain amount of time to form. Based on a conventional power supply, a short pulse voltage is superimposed, rapidly restoring the electric field voltage below the flashover voltage before the electric field has sufficient time to form a flashover. This power supply technology not only increases the maximum electric field voltage of the electrostatic precipitator but also effectively overcomes the back corona phenomenon, representing an important development direction for electrostatic precipitator power supplies. In the power supply of an electrostatic precipitator, the pulse generator converts the input DC power into high-voltage pulses to supply the electrostatic precipitator system.
[0003] For example, Chinese Patent Application No. CN201410215683.2 discloses a pulse generator comprising: a low-voltage rectifier for rectifying power frequency AC voltage into DC voltage; a low-voltage inverter for inverting the DC voltage into high-frequency AC voltage; a rectifier transformer for rectifying the high-frequency AC voltage into DC voltage; and a pulse generator for generating a resonant high-voltage pulse voltage based on the DC voltage and transmitting it to an electrostatic precipitator; wherein the low-voltage inverter is equipped with a high-frequency switch, the frequency of which is greater than the pulse frequency generated by the pulse generator.
[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:
[0005] The housing of common pulse generators is a rectangular box structure. Electrical components such as low-voltage rectifiers, low-voltage inverters, rectifier transformers, and pulse generators are all installed inside the box. These electrical components generate a lot of heat during operation, especially high-power pulse generators. However, the heat dissipation performance of common boxes is relatively poor, which often leads to excessively high temperatures inside the box, making electrical faults more likely and hindering the long-term stable and continuous operation of the pulse generator. Utility Model Content
[0006] This application provides a high-voltage pulse power supply pulse generator for electrostatic precipitators to improve the following technical problems:
[0007] The housing of common pulse generators is a rectangular box, which has poor heat dissipation performance. This often leads to excessively high temperatures inside the box, making it prone to electrical faults and hindering the pulse generator from working stably and continuously for a long time.
[0008] This application provides a high-voltage pulse power supply pulse generator for electrostatic precipitators, which adopts the following technical solution:
[0009] A high-voltage pulse power supply pulse generator for electrostatic precipitators includes an upper housing and a lower housing, both of which are rectangular parallelepiped structures. The bottom of the upper housing and the top of the lower housing are connected. The interior of the lower housing is used to install a high-power operating module, which includes an inverter, a rectifier transformer, and a pulse generator. The interior of the upper housing is used to install a low-power control module, which includes a control circuit module, a rectifier circuit module, and a switch module. One side of the lower housing is provided with a connecting pipe for connecting to a dust removal system. The other two sides of the lower housing are provided with heat dissipation fin modules. The remaining side of the lower housing is provided with an openable and closable lower housing door.
[0010] In one feasible technical solution of this application, the heat dissipation fin module includes 15-25 heat dissipation plates arranged vertically at intervals. The heat dissipation plates are rectangular in structure, and the heat dissipation gap between adjacent heat dissipation plates is between 3-6 cm.
[0011] In one feasible technical solution of this application, the heat dissipation fin module further includes a horizontally arranged upper reinforcing strip and a lower reinforcing strip, wherein the upper reinforcing strip connects the top outer sides of all the heat dissipation plates together, and the lower reinforcing strip connects the bottom outer sides of all the heat dissipation plates together.
[0012] In one feasible technical solution of this application, the connecting pipe is cylindrical, and a flange connecting plate is provided at the end of the connecting pipe away from the lower box.
[0013] In one feasible technical solution of this application, the central axes of the upper box and the lower box are vertically aligned, and the horizontal width of the upper box is 1.1-1.3 times the horizontal width of the lower box, and the horizontal length of the upper box is 1.1-1.3 times the horizontal length of the lower box.
[0014] In one feasible technical solution of this application, an openable and closable upper cabinet door is provided on each of the opposite sides of the upper cabinet.
[0015] In one feasible technical solution of this application, a reinforcing frame is provided on the top of the upper box, and lifting rings are provided at the four corners of the top of the reinforcing frame.
[0016] In one feasible technical solution of this application, the interior of the reinforcing frame is a hollow structure and is connected to the interior cavity of the upper box. The outer contour of the reinforcing frame is larger than the periphery of the upper box and forms a shielding hood on the four sides of the upper box. The bottom of the shielding hood is provided with a plurality of spaced heat dissipation holes.
[0017] In one feasible technical solution of this application, rollers are provided at the four bottom corners of the lower box.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] Since the low-power control module generates little heat during operation and its heat dissipation requirements are not high, the upper cabinet is used to house the low-power control module, which can meet its heat dissipation needs. However, the high-power working module generates more heat during operation and its heat dissipation requirements are higher. Therefore, the lower cabinet is used to house the high-power working module, and heat dissipation fin modules are added to both sides of the lower cabinet to improve its heat dissipation performance. This effectively prevents the temperature inside the lower cabinet from becoming too high, which is less likely to cause electrical faults and is conducive to the long-term stable and continuous operation of the pulse generator. Moreover, this vertical multi-cabinet design, which separates the high-power working module and the low-power control module, also facilitates daily inspections, checks, and maintenance by the staff, while also providing better equipment safety.

[0028] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.
[0029] This application discloses a high-voltage pulse power supply pulse generator for electrostatic precipitators. (Refer to...) Figure 1 The electrostatic precipitator high-voltage pulse power supply pulse generator includes an upper box 1 and a lower box 2, both of which are rectangular structures. The bottom of the upper box 1 and the top of the lower box 2 are connected. The interior of the lower box 2 is used to install a high-power working module, which includes an inverter, a rectifier transformer, and a pulse generator. The interior of the upper box 1 is used to install a low-power control module, which includes a control circuit module, a sorting circuit module, and a switch module. One side of the lower box 2 is provided with a connecting pipe 3 for connecting to the dust removal system. The other two sides of the lower box 2 are provided with heat dissipation fin modules 4. The remaining side of the lower box 2 is provided with a lower box door 21 that can be opened and closed.
[0030] The central axes of the upper box 1 and the lower box 2 are vertically aligned, and the horizontal width of the upper box 1 is 1.1-1.3 times the horizontal width of the lower box 2, and the horizontal length of the upper box 1 is 1.1-1.3 times the horizontal length of the lower box 2. Each of the two opposite sides of the upper box 1 is provided with an openable and closable upper box door 11.
[0031] In this embodiment, the heat dissipation fin module 4 includes 15-25 vertically spaced heat dissipation plates 41. The heat dissipation plates 41 have a rectangular structure, and the heat dissipation gap between adjacent heat dissipation plates 41 is between 3-6 cm. The heat dissipation fin module 4 also includes horizontally arranged upper reinforcing strips 42 and lower reinforcing strips 43. The upper reinforcing strips 42 connect the top outer sides of all heat dissipation plates 41 together, and the lower reinforcing strips 43 connect the bottom outer sides of all heat dissipation plates 41 together.
[0032] The heat dissipation fin module 4 designed above has a robust structure, is easy to manufacture and has a low cost. It has a large heat dissipation area and a good heat dissipation effect on the lower cabinet 2.
[0033] In this embodiment, in order to facilitate the connection of the connecting pipe 3 to the dust removal system, the connecting pipe 3 is cylindrical in shape, and a flange connecting plate 31 is provided at the end of the connecting pipe 3 away from the lower box 2.
[0034] In this embodiment, in order to facilitate the lifting and transportation of the heavy electrostatic precipitator high-voltage pulse power supply pulse generator, a reinforcing frame 5 is provided on the top of the upper housing 1, and lifting rings 6 are provided at the four corners of the top of the reinforcing frame 5, and rollers 7 are provided at the four corners of the bottom of the lower housing 2.
[0035] In order to improve the heat dissipation effect of the upper box 1 to a certain extent, the interior of the reinforcing frame 5 is hollow and connected to the internal cavity of the upper box 1. The outer contour of the reinforcing frame 5 is larger than the periphery of the upper box 1 and forms a shielding hood 51 on the four sides of the upper box 1. Multiple heat dissipation holes 52 are arranged at intervals at the bottom of the shielding hood 51.
[0036] The beneficial technical effects of the high-voltage pulse power supply pulse generator for electrostatic precipitators in this application embodiment are roughly as follows:
[0037] Since the low-power control module generates little heat during operation and its heat dissipation requirements are not high, the upper cabinet 1 is used alone to install the low-power control module, which can meet its heat dissipation needs. However, the high-power working module generates more heat during operation and its heat dissipation requirements are higher. Therefore, the lower cabinet 2 is used alone to install the high-power working module, and heat dissipation fin modules 4 are added to both sides of the lower cabinet 2, thereby improving the heat dissipation performance of the lower cabinet 2, effectively preventing the temperature inside the lower cabinet 2 from becoming too high, which is less likely to cause electrical faults and is conducive to the long-term stable and continuous operation of the pulse generator. Moreover, this vertical multi-cabinet design, which separates the high-power working module and the low-power control module, also facilitates the daily inspection, maintenance and other work of the staff, and also has better equipment safety.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
