| titleOfInvention | Granulating production system for nitro compound fertilizer solution |
| abstract | The utility model discloses a granulating production system for a nitro compound fertilizer solution, which comprises a solution elevated tank, wherein the top of the solution elevated tank is connected with an ammonium nitrate solution pipeline; the bottom of the solution elevated tank is sequentially connected with a two-stage evaporator, a separator, a liquid seal tank, an ammoniating tank, a mixing tank and a granulation tower in series; a temperature sensor is arranged in the granulation tower; a dust remover is arranged at the top of the granulation tower; a drying fan is arranged at the bottom of the granulation tower; a granulation shower nozzle of the granulation tower is connected with a branch pipe; a preheating valve is arranged on the branch pipe; the other end of the branch pipe is communicated with a tail gas chimney pipe of a device for preparing dilute nitric acid through a double pressurizing method; the tail gas chimney pipe is arranged with a tail gas expansion machine. The system has the advantages that heat of nitramine or nitro compound fertilizer solution with the concentration of 98.5 % and at the temperature of 158 to 168 DEG C as well as heat of the production tail gas is utilized to preheat the shower nozzle of the granulating machine, so that the use amount of the vapor is reduced, the phenomenon that materials are hung on a wall is avoided, the product quality is improved, and the normal production is ensured. |
