Technical Field

[0001] The utility model belongs to the technical field of combined soda production, and particularly relates to a hot air circulation structure of an ammonium chloride dry ammonium furnace capable of maintaining temperature in real time. Background Technique

[0002] Ammonium chloride (NH4Cl) is an important chemical raw material, showing small square or octahedral crystals in white or slightly yellow color. It is mostly a by-product of the soda-making industry. In chemical production, ammonium chloride can be by-produced while producing soda ash through the combined soda-making method, and is widely used in industries such as chemical fertilizers, medicine, electroplating, and welding.

[0003] Since ammonium chloride is easily decomposed into ammonia and hydrogen chloride when heated, it needs to be dried by the way of heat exchange between hot air and wet ammonium.

[0004] The ammonium chloride dry ammonium furnace is a device that uses hot air to dry ammonium chloride. However, the existing hot air circulation structure of the dry ammonium furnace lacks an effective heat energy collection and reuse mechanism, resulting in the insufficient utilization of heat energy in the furnace, high production energy consumption, and the wasted heat energy cannot be re-introduced into the dry ammonium furnace, causing energy waste; and there is a lack of temperature detection and control mechanism in the dry ammonium furnace, resulting in large temperature fluctuations in the furnace, which are difficult to be stable and cannot be adjusted according to the real-time temperature of the buffer tank.

[0005] Therefore, the existing dry ammonium furnace lacks an effective heat energy collection and reuse mechanism and temperature detection and control mechanism, resulting in high production energy consumption, energy waste, large temperature fluctuations, and inability to adjust according to the real-time temperature of the buffer tank.
