Description

Technical Field

[0001] This utility model relates to an insulated box structure for an electrostatic precipitator. Background Technology

[0002] For an electrostatic precipitator to operate efficiently, the temperature inside the electric field must be higher than the dew point temperature of the flue gas to prevent dust from caking and affecting dust removal, as well as to prevent electric field corrosion and extend the lifespan of the electrostatic precipitator. An important way to prevent condensation of the flue gas inside the electric field is to properly insulate the outer shell of the electrostatic precipitator to reduce the temperature drop inside the electric field.

[0003] Currently, the common method for insulating the shell of electrostatic precipitators is to directly weld support components onto the shell, then manually fill and wrap the insulation cotton on-site, and finally wrap it with profiled steel plates and fix it with bolts or welds. This process involves many steps, relies heavily on on-site manual labor, has a long construction period, and is difficult to control in terms of quality. In addition, the joints and installation holes are easily not properly sealed, leading to air leakage. When outside air enters the gap between the insulation layer and the shell, it creates a "chimney effect," continuously carrying away heat, severely reducing the insulation effect, and may cause the insulators and other equipment inside the shell to creep and be damaged due to condensation. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an insulated box structure for an electrostatic precipitator.

[0005] The technical solution adopted by this utility model to solve its technical problem is: An insulated box structure for an electrostatic precipitator includes a box shell, additional insulation panels fastened to the four outer sides of the box shell, the box shell including a box shell frame, a box shell mesh frame welded to the four outer sides of the box shell frame, a box shell plate welded to the inner side of the box shell mesh frame, and a hanging plate assembly structure welded to the outer side of the box shell mesh frame and arranged at equal intervals from top to bottom. The additional insulation panels include a plate frame with rectangular grids, a thin steel plate welded to the outer side of the plate frame, positioning screws welded to the inner side of the thin steel plate, a pressure plate that cooperates with the rectangular grids on the plate frame and is fixedly assembled with the positioning screws, insulation cotton for filling the rectangular grids tightly attached to the pressure plate, hook seats welded to the inner side of the plate frame and arranged at equal intervals from top to bottom, a hanging rod that passes through the hook seats and is fixed by welding, and a sealing ring pasted to the inner edge of the plate frame.

[0006] Preferably, the mounting plate assembly structure includes a hollow mounting plate body and mounting grooves located at the front ends of both sides of the mounting plate body.

[0007] Furthermore, the mounting groove includes an inclined opening section and a straight fastening section connected to the opening section.

[0008] Preferably, the inner sides of the two long sides of the plate frame are provided with inclined surfaces.

[0009] Preferably, the insulation material is glass wool.

[0010] Preferably, the sealing ring is a nitrile rubber sealing ring.

[0011] Preferably, the number of hook holders is the same as the number of mounting plate assembly structures.

[0012] The beneficial effects of this utility model are as follows: 1. Through the cooperation of the hanging plate assembly structure and the hook seat, the additional insulation board can be installed by snap-fit. During installation, simply align the position and move it diagonally downward to complete the hooking and sealing. The disassembly process is the reverse, which simplifies the installation and subsequent maintenance process, saves a lot of manpower and time costs, and improves work efficiency. In addition, the straight snap-fit ​​section of the hook groove provides a horizontal and stable mechanical locking structure for the hanging rod. This connection method can withstand the self-weight of the insulation board and possible external forces, avoiding detachment due to vibration or wind, and ensuring the safety and long-term reliability of the structure. 2. After the insulation board is installed, it will press tightly against the shell frame, causing the sealing ring to deform and effectively seal the gap between the board and the shell. The inclined surface design between adjacent insulation boards ensures tight contact, avoiding the formation of vertical grooves, preventing cold air infiltration and thermal bridging, effectively reducing heat loss, ensuring the temperature inside the electrostatic precipitator, especially the insulator chamber, preventing equipment failure caused by condensation and creepage, and improving energy utilization efficiency.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0015] Example like Figure 1-6 As shown, an insulated box structure for an electrostatic precipitator includes a box shell 1, additional insulation plates 2 fitted onto the four outer sides of the box shell 1, the box shell 1 including a box shell frame 11, a box shell mesh frame 12 welded onto the four outer sides of the box shell frame 11, a box shell plate 13 welded onto the inner side of the box shell mesh frame 12, and a hanging plate assembly structure 14 welded onto the outer side of the box shell mesh frame 12 and arranged at equal intervals from top to bottom; the additional insulation plates 2 include a plate frame 21 with rectangular grids, welded onto the plate... The frame 21 consists of a thin steel plate 22 on the outside, a positioning screw 23 welded to the inside of the thin steel plate 22, a pressure plate 24 with a rectangular grid on the frame 21 and fixedly assembled with the positioning screw 23, insulation cotton 26 for filling the rectangular grid and closely attached to the pressure plate 24, hook seats 26 welded to the inside of the frame 21 and arranged at equal intervals from top to bottom, a hanging rod 27 that passes through the hook seat 26 and is fixed by welding, and a sealing ring 28 pasted on the inner edge of the frame 21.

[0016] The mounting plate assembly structure 14 includes a hollow mounting plate body 141 and mounting grooves 142 located at the front ends of both sides of the mounting plate body 141.

[0017] The mounting slot 142 includes an inclined opening section 1421 and a straight fastening section 1422 that communicates with the opening section 1421.

[0018] It should be further explained that the hollow design of the mounting plate assembly structure 14 and the specific shape of the opening section 1421 and the straight fastening section 1422 in the hanging groove 142 work together with the hook seat 26 and the hanging rod 27 on the additional insulation plate. Through a simple "slanted downward" action, the hanging rod 27 is easily guided by the inclined opening section 1421 and finally slides into the straight fastening section 1422 to achieve vertical locking. This operation is not only labor-saving and quick, but also uses the mechanical structure to ensure the reliability of the connection and prevent loosening.

[0019] The inner sides of the two long sides of the frame 21 are provided with inclined surfaces 211. Specifically, when the additional insulation board 2 is installed on the four sides of the outer shell 1, the inclined surfaces of two adjacent additional insulation boards 2 can contact and stick together, which can avoid the groove between two adjacent additional insulation boards 2 and affect the aesthetics of the assembly.

[0020] In this embodiment, the insulation cotton 26 is glass wool. Glass wool not only provides insulation but also has a sound insulation effect, which can reduce the noise generated during the operation of the electrostatic precipitator.

[0021] In this embodiment, the sealing ring 28 is a nitrile rubber sealing ring. Nitrile rubber sealing rings have excellent oil resistance, acid and alkali resistance, wear resistance and aging resistance, and can maintain the sealing effect for a long time when used with the additional insulation board 2.

[0022] In this embodiment, the number of hook seats 26 is the same as the number of hanging plate assembly structures 14.

[0023] It needs to be further explained that when the additional insulation board 2 is installed into the shell 1, the hook seat 26 is first aligned with the hollow hanging plate body 141 inside, and then moved diagonally downward. At the same time as the hook seat 26 is embedded into the hanging plate body 141, the hanging rod 27 on the hook seat 26 enters the hanging groove 142 through the opening section 1421. After the hanging rod 27 enters the hanging groove 142 and falls completely into the straight fastening section 1422, the additional insulation board 2 completely presses the shell frame 11 tightly through displacement, and achieves a seal by squeezing the sealing ring 28, preventing ventilation between the additional insulation board 2 and the shell 1 and reducing the insulation effect of the additional insulation board 2.

[0024] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
