Embodiment approach

[0038] As an embodiment of the present invention, the steel wire cross section of the No. 1 spring 341 is rectangular, and the No. 1 spring 341 with a rectangular steel wire cross section cooperates with the square frame body 342 to improve the stability of the square frame body 342 when it shrinks. . In the present invention, the steel wire cross section of the No. 1 spring 341 is set as a rectangle, and the No. 1 spring 341 with a rectangular cross section moves with the square frame. On the one hand, the strength of the agitator 34 is improved; on the other hand, the Stirrer 34 aids in the stability of the soda ash crystals.

[0039] As an embodiment of the present invention, the No. 1 channel 321 is provided with a sealing unit 5; the sealing unit 5 is used to prevent the soda liquid from entering the No. 1 channel 321, and the sealing unit 5 is a high temperature resistant elastic bag 51; the high-temperature-resistant elastic bag 51 is a rectangular bag, and the high-te...

Abstract

The invention belongs to the technical field of heavy sodium carbonate production, and specifically relates to a high quality heavy sodium carbonate crystallization technology. A crystallizer adoptedby the technology comprises a box and also comprises a driving unit, an auxiliary unit, a No.1 airbag, a spiral steam pipe, a reaction box, and a controller. Through the cooperation among magnesium chloride, calcium chloride, and a surfactant, the granularity and whiteness of heavy sodium carbonate crystals are influenced; a magnesium chloride solution is added at first, then a calcium chloride solution is added, two solutions are fully mixed to form thick liquid, which acts on heavy ash mother liquor; thus the qualified rate of heavy sodium carbonate crystals is increased, and the whiteness of heavy sodium carbonate is improved.

Description

technical field [0001] The invention belongs to the technical field of heavy alkali production, in particular to a high-quality heavy alkali crystallization process. Background technique [0002] Heavy soda ash can be divided into ordinary heavy soda ash and high-quality heavy soda ash according to the advantages and disadvantages of chemical composition, and can be divided into ordinary heavy soda ash and super heavy soda ash according to different physical properties (mainly referring to heavy weight). Compared with heavy soda ash and light soda ash Due to its heavy weight, alkali dust is not easy to fly during use, which greatly reduces the loss of flying and environmental pollution. If the chemical composition enters the grade of high-quality heavy soda ash, it can also reduce equipment corrosion and increase the heat exchange capacity of equipment. Very popular among users. [0003] In the existing heavy alkali crystallization, the particle size and whiteness of the pr...
