Problems solved by technology

However, in the continuous production process, sometimes the heat in the crystallizer cannot be taken away, causing the temperature in the crystallizer to be too high and unable to hydrate and crystallize, resulting in the situation of stopping the alkali and cooling down

Abstract

The invention discloses a novel crystallizer for producing alkali, comprising a tank, upper and lower jackets enwrapping the outer wall of said tank, and upper and lower draft tubes mounted in said tank. The productive capacity is enhanced because in the invention the scroll and crystal heat transfer capability are increased and the temperature of inner crystallizer reduces to delay the feeding time of hydrate crystallizer for 11 min per time than the crystallizer used at present.

Description

technical field [0001] The invention relates to a crystallizer, in particular to a crystallizer for producing heavy soda ash. Background technique [0002] A crystallizer is disclosed in the Chinese patent titled "Crystalizer for Alkali Production", the patent number is 02282496.0, and the application date is December 31, 2002. A jacket is provided outside the body. Compared with the existing equipment, the equipment realizes the requirement of continuous hydration crystallization and achieves the purpose of continuous production. However, in the continuous production process, sometimes the heat in the crystallizer cannot be taken away, causing the temperature in the crystallizer to be too high to hydrate and crystallize, resulting in the situation of stopping the alkali and cooling down. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a novel crystallizer for soda production. The heat e...
