Rapid heating device for sodium-removed red mud

The utility model relates to a rapid heating device for sodium-removed red mud, which belongs to the field of metallurgy and chemical engineering and is characterized in that a feed port is arranged at the top of a tank of the rapid heating device for the sodium-removed red mud, the feed port is communicated with a feed pipe inside the tank, and a heat exchange plate is communicated with the feed pipe; materials enter from the feeding port and then leak out of the heat exchange plate through the feeding pipe to make contact with hot steam for heat exchange, and therefore the purpose of heating through the hot steam is achieved. The rapid heating device for the sodium-removed red mud fully utilizes channelized waste heat low-pressure inferior steam, effectively improves the steam utilization rate, reduces the use amount of medium and high pressure steam, reduces the unit consumption of sodium-removed steam, shortens the cleaning period, reduces the cleaning cost, and is suitable for direct heating of various r
