Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal metallurgy, in particular to a novel anode furnace mouth water jacket device. Background Art

[0002] The anode furnace mouth needs to be charged and discharged, accompanied by the erosion of high-temperature melt of thousands of degrees, which has a great impact on the service life of the furnace body. Therefore, the furnace mouth is protected by a furnace mouth water jacket device to ensure the normal production of anode furnace refining. The working principle of the anode furnace mouth water jacket device is: cooling water is transported to the water jacket through a cold water pump, and enters the hot water pool after sequential heat exchange. The water in the hot water pool is cooled by a cooling tower and then returns to the cold water pool, forming a water circulation system to save water resources. Under the sequential heat exchange of the furnace mouth water jacket, the overall temperature of the furnace mouth area is controlled to be stable. Due to the layout of other devices, there are differences in the heat load of each area, especially the heat load on the side opposite to the combustion nozzle is large. The original water jacket device has poor cooling effect, which can easily cause the water jacket device to deform. The water jacket device leaks and cannot be welded, so it has to be shut down. The deformation of the water jacket will cause a gap between the water jacket and the refractory bricks. If it is not repaired in time, the furnace mouth will turn red, and in severe cases, the furnace body will be burned through. The new anode furnace furnace mouth water jacket device has a targeted upgrade and renovation. By increasing the number of circulating water groups in areas with large heat loads, the heat exchange efficiency is enhanced and the water jacket device is protected to a great extent.
