AI Technical Summary
Technical Problem
In the existing rotary kiln, the highly corrosive acidic gases such as selenium vapor and sulfur dioxide during the copper anode mud roasting process result in a shortened service life of the flue gas passage and high maintenance and operating costs.
Method used
The rotary kiln gas duct for calcining copper anode mud is equipped with T-shaped anti-corrosion copper anode mud, using acid-resistant metal materials and polytetrafluoroethylene lining, combined with cooling water channels and cooling pools, to absorb heat through cooling water and reduce high temperature and acid corrosion.
Benefits of technology
It reduces operating costs, extends equipment lifespan, achieves low-cost high-temperature and acid resistance, and has a simple structure that facilitates maintenance.

Abstract
This utility model relates to the field of rotary kiln technology in pyrometallurgical processes, and specifically discloses a T-type anti-corrosion copper anode mud roasting rotary kiln gas guide pipe, including a T-type rotary kiln gas guide pipe, an anti-corrosion lining, a cooling pool, and cooling water pipes. The gap between the T-type rotary kiln gas guide pipe and the anti-corrosion lining is set as a cooling water channel. The cooling pool is installed at the top of the T-type rotary kiln gas guide pipe. The left and right ends of the T-type rotary kiln gas guide pipe are respectively provided with a first gas guide pipe outlet and a second gas guide pipe outlet. The cooling water pipes are arranged around the T-type rotary kiln gas guide pipe. The T-type rotary kiln gas guide pipe includes a horizontal T-type gas guide pipe and a vertical T-type gas guide pipe. Both the horizontal and vertical T-type gas guide pipes are cylindrical and are welded together. This utility model provides a T-type anti-corrosion copper anode mud roasting rotary kiln gas guide pipe. This equipment has low operating costs, achieves high temperature resistance at low cost, and solves the problem that the acid-resistant lining used is not resistant to high temperatures.
