Abstract

The invention belongs to the field of inorganic synthesis and particularly relates to a sulfamic acid production apparatus and method. In specific conjunction with the characteristics and demands of asulfamic acid production process, setting manner and position of a feeding pipe of the sulfamic acid production apparatus are re-designed and reformed in specific manner; key process indexes and parameters in the reaction process are strictly controlled, consumption ratio and quantity of fuming sulfuric acid are decreased at the premise of not reducing product production quality; therefore, the technical problem is solved that high production cost is caused due to high consumption of fuming sulfuric acid in the prior art.

Description

technical field [0001] The invention belongs to the field of inorganic synthesis, and more specifically relates to a device and method for producing sulfamic acid. Background technique [0002] The largest raw material consumption of the sulfamic acid production system is oleum (105% acid), followed by urea. Under normal conditions of this system, the unit consumption of oleum is about 2.4-2.5t, and the unit consumption of urea is about 0.39-0.40t (that is, the amount of fuming sulfuric acid and urea needed to produce one ton of sulfamic acid finished product). The ratio of fuming sulfuric acid to urea is generally about 6.2-6.4. In order to control the manufacturing cost and adapt to the increasingly severe market competition situation, the proportion of fuming sulfuric acid consumption can be reduced to maximize the cost reduction and efficiency increase. However, how to reduce the proportion of fuming sulfuric acid consumption has long been short of effective measures. ...
