[0003] see figure 1 , it has a cathode box 101 (which is also the beam on the top of the electrostatic precipitator), a dust collection plate 102, and an electrostatic precipitator top plate 103. The electrostatic precipitator top plate 103 is originally straight, but after a long time of use, the electrostatic precipitator top plate 103 is corroded by gas , Oxygen oxidation, particle dust wear, rain erosion and other reasons cause the strength of the top plate 103 to decrease, resulting in collapse and deformation

Embodiment 1
[0028] Step 1: Determine the 5 steel beams 201 that need to be manufactured according to the collapsed area of the electric precipitator of the No. 5 sintering machine at Shaoguan Steel. Welded with channel steel to make 5 steel beams 201. The length of the steel beam 201 is longer than the two cathodes. The distance of box 101 is 300mm long, and one hole φ28 for bolt 203 is opened at each side 300mm of the midpoint of steel beam 201; 5 small steel beams 205 are welded with channel steel, and each small steel beam 205 consists of two The channel steel is welded into a small hollow square beam. A hole φ28 for bolt 203 is opened at each side 300mm of the midpoint of the small steel beam 205. The distance between the two holes on the small steel beam 205 and the steel beam 201 is 600mm. The distance is equal to 600mm, the total length of the small steel beam 205 is 850mm longer than the distance between the two holes of 600mm by 250mm; 10 screws 203M27 with a length of 1.1 meters...

The invention relates to a correcting method for a collapse electric dedusting top plate. The method comprises the steps that the quantity a of steel beams which are needed to be manufactured is judged according to the size of the collapse area; shut down is carried out on electric dedusting, poisonous gas inside the electric dedusting is totally discharged, and gas inside the electric dedusting is replaced with air; a jack is arranged between the center of the steel beams and the center of small steel beams; the collapse top plate is lifted by the force of the jack through the small steel beams, screw rods and a base plate; after the to-be-collapsed top plate is lifted to the appropriate position, two nuts between the two screw rods are tightly screwed; correcting is completed on one of the collapse positions on the electric dedusting top plate. The method has the advantages that the cost is low, the time for shut down and production stopping is short, and the implemented electric dedusting top plate is higher in strength.
Description
Technical field [0001] The invention belongs to the technical field of electric dust removal and relates to a method for correcting a collapsed electric dust removal top plate. Background technique [0002] Electrostatic precipitator has a wide range of applications. Electrostatic precipitators are generally used in conjunction with blowers or exhaust fans. The method involved in this patent is applied to electric precipitators used in conjunction with exhaust fans. The air pressure in the electrostatic precipitator is lower than the atmospheric pressure, and the housing of the electrostatic precipitator bears the pressure from the outside to the inside. The method involved in this patent is used to correct the inward collapse due to gas corrosion, oxygen oxidation, particle dust wear, rain erosion, etc. The top plate of the electrostatic precipitator. [0003] See figure 1 It has a cathode box 101 (also a beam on the top of the electrostatic precipitator), a dust collecting plate...
