[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] When in use, the smoke from the electric arc furnace enters the smoke guide tube 2 through the smoke inlet pipe 1 and is cooled by the cooling water in the cooling assembly 7. The smoke is then guided to the ash hopper 4 through the fan 3. At this time, the smoke can be filtered by the filter element 83 in the filter tube 81 through the smoke guide hole 10. The filter element 83 can efficiently remove fine particles in the smoke to ensure that the emitted smoke meets national or local environmental protection standards. The filtered airflow is guided to the connecting hood 11 through the middle of the filter element 83 and the connecting pipe 85 and is discharged from the smoke exhaust pipe 12.

[0036] In summary, the dynamic treatment device for smoke from an electric arc furnace is used in conjunction with an outer sleeve 71, a water inlet pipe 72, a water outlet pipe 73 and a spiral coil 74. The spiral coil 74 runs through the smoke guide tube 2. When the smoke from the electric arc furnace enters the smoke guide tube 2, the cooling water in the outer sleeve 71 and the spiral coil 74 can fully contact with the high-temperature smoke, thereby improving the cooling efficiency, thereby effectively improving the cooling effect of the device. By providing a disassembly hole 13, when the user needs to disassemble and replace the filter element 83 in the device, the user can first place and install two clean filter elements 83 in the two filter tubes 81 on the left through the disassembly hole 13, and limit and fix them through the limit plate 84, the connecting pipe 85 and the rotating disk 86. At this time, the user presses the push plate 96 to move downward, and the push plate 96 drives the clamping plate 93 to move downward through the push rod 95 to squeeze the support The spring 94 is disengaged from the engagement with the protrusion 65. At this time, the user can quickly drive the control rod 63 to rotate by the rotating block 64. The control rod 63 drives the rotating disk 62 to rotate through the rotating rod 61. The rotating disk 62 replaces the used filter element 83 with a clean filter element 83 through the left-right symmetrical filter cylinder 81. At the same time, the control rod 63 drives the protrusion 65 to rotate one hundred and eighty degrees. At this time, the user releases the push plate 96 to make the locking plate 93 re-engage with the protrusion 65. The entire replacement process is fast and convenient without stopping the machine, so that the equipment can perform continuous processing operations. At this time, the user can rotate the rotating disk 86 to disassemble and remove the limit disk 84 and the used filter element 83, thereby effectively facilitating the user to replace the filter structure of the device without stopping the machine, improving the convenience and safety of its operation, facilitating the user's use, and solving the problems raised in the above-mentioned background technology.
