The utlity model has following advantage:
1, can effectively reduce anode-baking furnace furnace bottom surface temperature, protect basic structural strength, and then avoid structural destruction body of heater.
2, reduce furnace bottom flame-proof thermal insulation material consumption, save anode-baking furnace masonry cost.
3, reduce furnace bottom accumulation of heat loss, can accelerate the heat-up rate of stove simultaneously, have remarkable energy saving effect.
4, can accelerate to cool off the speed of cooling of furnace chamber, obviously improve the furnace operating condition that takes on.
5, the gas communication of furnace bottom cooling process produces " hot furnace bottom " effect to furnace bottom, helps improving the stove actual temperature to setting the accordance of roasting curve.
6, the device that adopts refrigerating unit economical and practical, that adopted simple in structure, easy to implement.
