Description

Technical Field

[0001] The utility model relates to the technical field of anode furnace flue gas dust collection, in particular to a novel anode furnace flue gas system dust collection device. Background Art

[0002] The rotary anode furnace adds the molten copper from the converter into the furnace body for fire refining. Through oxidation and reduction operations, harmful impurities in the copper are removed, and qualified anode plates that meet the requirements of electrolytic refining are produced through disc casting. During the operation, a large amount of high-temperature flue gas will be generated.

[0003] After searching, the patent announcement number CN211753260U discloses a fixed anode furnace flue gas dust removal device with filter bag protection, including a smoke exhaust fan, a bag dust collector and an inlet smoke pipe. The inlet smoke pipe is provided with a working door. The bag dust collector is equipped with a plurality of filter bags. A protective layer is adsorbed on the outer wall of each filter bag, and the protective layer is composed of diatomaceous earth particles. The dust removal device is improved on the basis of the existing bag dust removal device, which effectively solves the problem of filter bag sticking, prolongs the service life of the filter bag, and has significant economic benefits.

[0004] The CN211753260U in the prior art effectively solves the problem of filter bag sticking during use, prolongs the service life of the filter bag, and has significant economic benefits. However, in actual flue gas treatment, when the gas containing smoke flows in the air intake pipe for a long time, the particles in the smoke will adhere to the inner wall of the pipe, which will cause gas circulation difficulties after long-term use, so it still needs to be improved.

[0041] A waste discharge pipe 20 is embedded and fixed on the bottom end surface of the collecting hopper 21, and a valve is installed on the waste discharge pipe 20 through a flange. The waste discharge pipe 20 is embedded and fixed on the bottom end surface of the collecting hopper 21, so that the attachments generated by beating in the intake pipe 17 can be discharged into the collecting hopper 21 for collection, and the valve on the waste discharge pipe 20 can be opened to discharge the internal attachments.
