Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] The reverberatory furnace smelting regenerated copper method adopted in the present invention directly mixes part of the high-temperature flue gas of the reverberatory furnace 1 with the combustion-supporting air to form a combustion-supporting gas with a higher temperature and a lower oxygen concentration, so as to improve the uniformity of temperature distribution in the reverberatory furnace 1 , reduce the local high temperature, realize high wind temperature, low oxygen concentration combustion in the reverberatory furnace 1, thereby reducing the burning loss of metal, and the amount of returned smoke accounts for 30-50% of the total flue gas volume of the reverberatory furnace 1. The negative pressure in the horizontal flue 2 is strictly controlled, and the negative pressure of the horizontal flue 2 behind the gate 3 is controlled at...
