Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and specifically relates to a cleaning and dust removal device. Background Technique

[0002] An electric arc furnace is a device used for melting metals, mainly used for smelting non-ferrous metals (such as copper, lead, zinc, etc.) and alloy steel, and can also be used in metal processing processes such as welding and cutting. It converts electrical energy into heat energy by generating a high-temperature current discharge channel and produces a local melting area in the furnace.

[0003] The electric arc furnace cleaning and dust removal device is an environmental protection device designed specifically for dealing with the high-temperature flue gas generated during the steelmaking process of the electric arc furnace. There are many deficiencies in the existing electric arc furnace cleaning and dust removal devices during actual use, which greatly affect the convenience of operation and the maintenance efficiency. First, in terms of impurity cleaning, the traditional devices are often not designed user-friendly, resulting in the need for operators to enter the equipment interior or use complex tools when cleaning the dust and impurities in the furnace or the dust removal equipment. This increases the cleaning difficulty and poses safety hazards. Second, the disassembly process of the traditional dust removal device is also relatively cumbersome. Many devices lack a modular structure in design, and it takes more time to disassemble and replace components, and the equipment may be damaged or have poor sealing during the disassembly process, further affecting the dust removal effect and the normal operation of the equipment. This inconvenience not only affects the maintenance cycle of the equipment but may also lead to production stagnation and economic losses. Content of the Utility Model
