Abstract
The utility model relates to an energy-saving ring type industrial kiln which is the improvement of the existing tunnel kiln. The adopted technical scheme is as follows: a kiln body tunnel is closely ring-shaped and is divided into an incoming/outgoing section, a preheating section, a high-temperature section and a cooling section. Coal gas burning nozzles and smoke discharging openings are fixedly arranged on the circumference at intervals and are respectively connected with a gas main pipe and a smoke discharging main pipe. Coal burning nozzle valves are opened and closed sequentially to lead fire points to move, so as to lead materials in the kiln to generate a relative motion and sequentially pass through all sections to finish roasting; smoke discharging opening valves are sequentially opened and closed to lead cold combustion-supporting wind and hot smoke to always exchange heat with the materials in the kiln in a counter current way. A kiln cover is a movable prefabricated slab, is moved away during discharging and is covered up after charging. Along with the discharging and charging of the incoming/outgoing section, the absolute positions of other sections constantly change so as to form a continuous production.
