1. A reaction system for preparing soda ash, characterized in that, comprising:
a carbonization tower, a reaction crystallization tower and a first micro-interface unit;
a material outlet is disposed at a bottom of the carbonization tower, and the material outlet is connected to the reaction crystallization tower;
the first micro-interface unit comprises a first micro-interface generator and a second micro-interface generator, wherein the first micro-interface generator is disposed below a liquid level in the carbonization tower, the second micro-interface generator is disposed above the first micro-interface generator, and a connecting pipe is disposed between the second micro-interface generator and the first micro-interface generator;
the first micro-interface generator is connected with an ammonia gas pipeline and a carbon dioxide pipeline; after ammonia gas and carbon dioxide are dispersed and broken into micron-sized bubbles in the first micro-interface generator, the micron-sized bubbles enter the carbonization tower;
a plurality of baffles is arranged in the carbonization tower from top to bottom, wherein all of the plurality of baffles are staggered and are arranged below the first micro-interface generator,
wherein the plurality of baffles are disposed obliquely downward in a direction away from a side wall of the carbonization tower; wherein a number of the baffles is three, and the three baffles are distributed at equal angles along a circumferential direction of an outer wall of the carbonization tower; wherein an uppermost one of the three baffles has an inclination angle of 35°, a middle one of the three baffles has an inclination angle of 45°, and a lowermost one of the three baffles has an inclination angle of 55°;
wherein a reinforced pipeline is disposed outside the carbonization tower, an inlet of the reinforced pipeline is connected to the side wall of the carbonization tower, and an outlet of the reinforced pipeline is connected to the second micro-interface generator;
wherein the second micro-interface generator is located at a top of the carbonization tower, a gas pipeline is disposed between the carbonization tower and the second micro-interface generator, and gas above the liquid level in the carbonization tower enters the second micro-interface generator through the gas pipeline.
