[0002] Brass rod is an alloy rod composed of copper and zinc. It is widely used in mechanical processing workshops. There must be a lot of brass scrap generated or used in the manufacture of brass rods. The recycling price of brass scrap is far less than one-tenth of its raw material, and the economic loss is huge. Therefore, in order to control costs, brass scrap will be smelted and purified for recycling, or the purified pure copper will be sold. A smelting furnace will be used in this process.

[0003] In the process of smelting brass rods, a gas protection purification device is often used to protect the smelting environment, prevent oxygen and other impurities from entering the furnace, and purify the gas in the furnace. When purifying the gas in the furnace, adsorbents are often used to adsorb and remove gas impurities in the furnace, such as activated carbon, molecular sieves, etc. However, after long-term use, the adsorbent will gradually become saturated and lose its adsorption capacity during the process of adsorbing and removing gas impurities, resulting in a poor gas purification effect. Therefore, the present application proposes a gas protection purification device in the process of brass rod smelting. Summary of the invention
