Abstract

The invention provides a steam rotary drying system for ammonium salt and a method for preparing the ammonium salt. The steam rotary drying system is used in an ammonium salt drying process for the first time, a novel energy-saving and environmental-friendly ammonium salt drying technology is proposed, and the ammonium salt steam rotary drying system with the less moisture, low product breakage rate, high thermal efficiency, low power consumption, stable operation and energy conservation and the method for preparing the ammonium salt are provided. The steam rotary drying system for the ammonium salt comprises a feeding device, a steam rotary dryer, a conveying device, a vibration conveying cooling sieving machine and a tail gas dedusting device. The steam rotary dryer comprises a feeding cover, a rotary cylinder, a discharge cover, a transmission device and multiple heat exchange tubes arranged in the rotary cylinder. The hot air inlet of the steam rotary dryer is in a countercurrent mode.

Description

technical field [0001] The invention relates to drying equipment for ammonium salts and a drying method for ammonium salts, in particular to equipment for drying ammonium salts using a steam rotary drying system and a method for preparing dry ammonium salts. Background technique [0002] With the development of our society, the demand for ammonium salts in civil and industrial applications is also increasing. The drying of ammonium salt is a process with high energy consumption. Continuously improving and improving the level of drying equipment in the ammonium salt industry will definitely play an important role in promoting the development of my country's ammonium salt industry. With the rapid development of technology and technology in my country's ammonium salt industry, higher requirements are put forward for drying: deep drying is required to prevent materials from agglomerating during long-term storage; energy consumption needs to be reduced, thereby reducing operating...
