Description

Technical Field

[0001] The invention relates to the technical field of power plant beam heaters, in particular to a waterproof device for an electrostatic precipitator beam heater. Background Art

[0002] Due to the poor working environment of the electrostatic precipitator equipment in power plants, the equipment is corroded by high-temperature flue gas for a long time and liquefied flue gas discharged from the chimney. The beam heater needs to be started frequently for drying on rainy and snowy days. However, the iron waterproof shell of the beam heater cannot reliably guarantee its sealing. During unit maintenance, sledgehammers are often used to knock and install the unit, causing most of the beam heater's waterproof shells to deform and loosen, and the waterproof performance is greatly reduced. The consequence is that the beam heater's wiring screws are often severely rusted within a year, and reliable contact cannot be guaranteed, and the circuit is prone to open circuit failure.

[0003] Due to the working environment of the power plant beam heater, water vapor cannot be strictly isolated, causing serious corrosion of its wiring parts and loss of its normal working function. The resulting increase in humidity in the beam room and reduction in insulation inside the electrostatic precipitator electric field cause high-frequency power supply discharge, which in turn causes the electrostatic precipitator high-frequency power supply to trip, resulting in a major safety accident.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, and this embodiment provides an electrostatic precipitator beam heater waterproof device, which is sleeved on the surface of the existing electrostatic precipitator beam heater to achieve a waterproof effect.

[0028] A waterproof device for an electrostatic precipitator beam heater, comprising:

[0029] A waterproof shell 100, wherein the inner surface of the waterproof shell 100 is provided with a sleeve groove 103; and,

[0030] An extrusion ring 105 connected to the bottom of the waterproof shell 100, a raised ring 106 connected to the bottom of the extrusion ring 105, and a side groove 101 is provided at the connection between the extrusion ring 105 and the waterproof shell 100; and,

[0031] When the raised ring 106 is squeezed, the squeeze ring 105 moves upward, the side groove 101 is filled, and the bottom of the raised ring 106 becomes horizontal.

[0032] Align the sleeve groove 103 on the surface of the waterproof shell 100 with the waterproof card slot of the heater, and press the waterproof shell 100 on the surface of the waterproof card slot, so that the waterproof card slot goes deep into the sleeve groove 103, and the raised circle 106 contacts the iron plate around the waterproof card slot, and the raised circle 106 is squeezed, and the raised circle 106 and the squeezing circle 105 are deformed, and the upper end of the squeezing circle 105 contacts the surface of the waterproof shell 100, and the side groove 101 disappears. At this time, the downward raised circle 106 can prevent water from contacting the waterproof card slot of the heater.

[0033] Example 2, reference Figures 1 to 4, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a fitting block 107 inside the sleeve groove 103 in the waterproof device of the electrostatic precipitator beam heater, thereby avoiding the problem of slow water infiltration.

[0034] Specifically, an inner groove 102 is provided inside the waterproof shell 100 , and the middle part of the inner groove 102 and the sleeve groove 103 forms a fitting ring 108 .

[0035] A fitting block 107 is fixed inside the sleeve groove 103 , and the inner surface of the fitting block 107 is an upwardly contracted inclined surface.

[0036] The fitting blocks 107 are symmetrically arranged inside the sleeve groove 103 , and the vertical sides of the fitting blocks 107 fit with the inner surface of the sleeve groove 103 .

[0037] After the heater waterproof slot enters the sleeve slot 103, the fitting block 107 is squeezed, and the fitting block 107 is deformed and fits on the top of the drain slot, increasing the friction between the waterproof shell 100 and the waterproof slot to prevent water from penetrating.

[0038] Example 3, reference Figures 1 to 4 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a magnet 104 at the bottom of the fitting ring 108 in the waterproof device of the electrostatic precipitator beam heater, which increases the stability of the waterproof shell 100.

[0039] Specifically, the magnet 104 is fixed to the bottom of the fitting ring 108 , and the bottom of the magnet 104 is flush with the bottom of the fitting ring 108 .

[0040] The bottom of the fitting ring 108 is flush with the bottom of the pressing ring 105 .

[0041] The bottom of the fitting ring 108 is provided with a slot, and the magnet 104 is fixed inside the slot.

[0042] When the heater waterproof slot is completely in contact with the bottom of the sleeve slot 103 , the fitting ring 108 is located inside the waterproof slot, and the magnet 104 is attracted to the inner surface of the waterproof slot by magnetic force, thereby increasing the stability of the waterproof shell 100 .
