Problems solved by technology
The above two processing methods are all desulfurization systems, and their disadvantages are that there are many equipments, and there may be many equipment failure points, which will lead to a large maintenance workload; the configuration is scattered and the floor area is large; the project investment and operating costs are high.
[0003] Therefore, the current system and method for processing the flue gas of the anode furnace still needs to be improved.

Embodiment
[0049] The treatment of the anode furnace flue gas generated during the operation of the two anode furnaces mainly includes the following steps (refer to Figure 5-6 ):
[0050] 1) Cool down once
[0051] The two anode furnaces are sucked by their respective exhaust fans, and the temperature is lowered once (waste heat boiler, secondary combustion chamber, anode furnace hood) to below 350 degrees Celsius.
[0052] 2) Secondary cooling and dust removal
[0053] The flue gas from the anode furnace that has been cooled for the first time is sucked into the air cooler for the second cooling, and the temperature of the flue gas is reduced from 350 degrees Celsius to about 150 degrees Celsius. After that, the flue gas enters the bag filter for purification, reducing the dust concentration of the flue gas to 20mg / Nm 3 the following.
[0054] 3) Flue gas treatment
[0055] According to the process operation of copper refining process, it can be known that in a certain period of t...

The invention discloses anode furnace smoke treatment system and method. The system comprises a first cooling device, a second cooling device and a dust collector. The method includes: cooling anode furnace smoke for the first time to lower the temperature of the second cooling device to below 350 DEG C; secondarily cooling the anode furnace smoke which is cooled for the first time so as to lower the temperature of the anode furnace smoke to 150 DEG C; and dedusting the anode furnace smoke which is cooled secondarily so as to obtain dedusted anode furnace smoke. The anode furnace smoke treatment system and method have such the advantages that the system and method are energy-saving and environment-friendly and degree and efficiency of treating the anode furnace smoke can be increased effectively.
Description
technical field [0001] The invention relates to the field of metallurgy. In particular, the present invention relates to systems and methods for treating anode furnace flue gas. Background technique [0002] The anode furnace is the core equipment in the refining process of copper smelting, and a large amount of anode furnace flue gas is generated during the smelting process. At present, there are two ways to treat the flue gas of the anode furnace, one is to set up a separate anode furnace tail gas desulfurization system to directly empty the anode furnace flue gas after treatment, and the other is to send the flue gas to the environment flue gas desulfurization system for treatment . The above two processing methods are all desulfurization systems, and their disadvantages are that there are many equipments, and there may be many equipment failure points, which will lead to a large maintenance workload; the configuration is scattered and the area is large; the project inv...
