They heat boiler water through high-voltage electrode discharge, eliminating the need for low-voltage transformers and featuring high efficiency and rapid adjustment. Electrode boiler steam superheaters are devices used to heat saturated steam into superheated steam. They are widely used in electrode boilers, chemical production, and other fields to improve steam work efficiency and cycle thermal efficiency.

[0015] according to Figures 1-5 As shown in the figure, this embodiment proposes a steam superheater control cabinet for an electrode boiler, including a cabinet body 1 and a cabinet door 2. The cabinet body 1 is provided with a heat insulation plate 3 inside. The front side of the heat insulation plate 3 is an electrical component compartment, and the rear side of the heat insulation plate 3 is a heating compartment. An installation plate 4 for installing electrical components is suspended inside the electrical component compartment. A first ventilation mechanism is provided on both sides of the installation plate 4, and a second ventilation mechanism is provided at the bottom of the installation plate 4. The installation plate 4 and the electrical components are located at the middle of the first ventilation mechanism and the second ventilation mechanism.

[0016] This control cabinet divides the cabinet body 1 into a heating chamber and an electrical component chamber through a heat insulation plate 3. The electrical component chamber contains multiple electrical components used to control this device. The suspended mounting plate 4 further reduces the contact area between the mounting plate 4 and the cabinet body 1, further reducing heat transfer. At the same time, this device uses a first ventilation mechanism and a second ventilation mechanism to dissipate heat from the electrical components, increasing the heat dissipation effect and extending the service life of the electrical components. Moreover, the mounting plate 4 is located in the middle of the first ventilation mechanism and the second ventilation mechanism, thus dissipating heat from both sides to the electrical components on the mounting plate 4, further increasing the heat dissipation effect on the electrical components.

[0017] The first ventilation mechanism includes a first mounting frame 5, a first cooling fan 6, ventilation holes 7, and a first air guide 8. The first mounting frame 5 is fixed on the inner walls of both sides of the cabinet 1. The first mounting frame 5 is provided with a plurality of mounting slots for mounting the first cooling fan 6. The side wall of the cabinet 1 is provided with a plurality of ventilation holes 7 at positions corresponding to the mounting slots. The side of the first mounting frame 5 near the cabinet 1 is provided with a plurality of first air guide 8 vertically downwards and connected to the second ventilation mechanism.

[0018] By activating the first cooling fan 6, the first cooling fan 6 on the first mounting frame 5 on one side blows air into the cabinet 1, and the first cooling fan 6 on the first mounting frame 5 on the other side exhausts air out of the cabinet 1. Together with the ventilation holes 7 on the side wall of the cabinet 1, air circulation is formed, thereby dissipating heat from the electrical components on the mounting plate 4.

[0019] The second ventilation mechanism includes a second mounting frame 9 and a second cooling fan 10. The top of both ends of the second mounting frame 9 is connected to the bottom of the first mounting frame 5. Two sets of second cooling fans 10 are symmetrically mounted on the second mounting frame 9. Multiple sets of support columns 11 are provided at the bottom of the second mounting frame 9. The bottom of the support columns 11 is fixedly connected to the inner wall of the cabinet 1. Second air guide channels 12 are provided on the side walls at both ends of the second mounting frame 9, which are aligned with the first air guide channel 8.

[0020] By activating the second cooling fan 10, the second cooling fan 10 blows air upwards, thereby dissipating heat from the bottom of the electrical components on the mounting plate 4. At the same time, the first air guide 8 on the first mounting frame 5 and the second air guide 12 on the second mounting frame 9 are connected, forming an air cavity in conjunction with the design of the support column 11, thereby ensuring air circulation and increasing the heat dissipation effect of the second fan.

[0021] A filter screen 13 is provided on the inner side of the first mounting frame 5 at the position corresponding to the mounting groove, and a limit block 14 is rotatably installed at each of the four corners of the filter screen 13.

[0022] The filter screen 13 protects the interior of the cabinet 1, while the installation method of limiting the filter screen 13 by rotating the limit block 14 greatly facilitates the disassembly and replacement of the filter screen 13.

[0023] The upper end of the mounting plate 4 is symmetrically equipped with L-shaped mounting blocks 15, and the ends of the L-shaped mounting blocks 15 are fixedly connected to the top inner wall of the cabinet 1.

[0024] The heat insulation board 3 includes a first partition 16, a second partition 17 and a middle frame 18. The first partition 16 and the second partition 17 are located on both sides of the middle frame 18 and are sealed to the middle frame 18. After sealing, a vacuum treatment is performed.

[0025] By employing a vacuum method, the heat insulation effect of the heat insulation board 3 is further enhanced.

[0026] The heating chamber is equipped with a heating mechanism for superheating steam, and the top of the heating chamber is also equipped with a temperature gauge 19 and a pressure gauge 20.

[0027] The heating mechanism in this device uses an existing steam reheating structure, which will not be described in detail here.

[0028] The control cabinet for the superheater of the electrode boiler is divided into a heating chamber and an electrical component chamber by a heat insulation plate 3. The heating chamber is equipped with a heating mechanism for heating the steam, while the electrical component chamber is used for the installation of electrical components. The heat insulation plate 3 reduces the heat transfer to the electrical component chamber, thus providing initial protection for the installed electrical components. At the same time, heat dissipation structures are provided on both sides and the bottom of the electrical component chamber to increase the heat dissipation effect and further extend the life of the electrical components. The mounting plate 4 used to install the electrical components adopts a hanging installation method, which further reduces the installation contact area, thereby reducing heat transfer and further extending the service life of the electrical components.
