Abstract
The utility model discloses a device used for preparing ammonia, which relates to the device used for preparing industrial ammonia. The device is characterized in that the structure of the device comprises a liquid ammonia bottle, an ammonia preparing tank, an absorption tower, a circulating tank, a circulation cooling device, and an ammonia efferent duct. The device of the utility model pumps the ammonia from the bottom of the ammonia preparing tank by adopting a ring porous tube, thereby guaranteeing the ammonia to be diffused uniformly and to be fully contacted with water. The ammonia is mixed uniformly by circulation, thereby ensuring consistent ammonia concentration. Heat released when the ammonia is dissolved is exchanged through circulation anda heat exchanger, thus decreasing the temperature of an ammonia-water system, and moreover, the temperature can be controlled between 40 and 50 DEG C, thereby reducing ammonia volatilization; besides, the evaporated ammonia is absorbed by adopting the absorption tower. When the ammonia concentration of circulating water achieves 5-8 percent, supplementary ammonia is released into production and usage after achieving a compound concentration requirement.
