Description

Technical Field

[0001] The utility model relates to the technical field of dissolving tanks, and more specifically to a sodium carbonate dissolving tank. Background Art

[0002] Sodium carbonate is one of the important chemical raw materials and is widely used in light industry, daily chemicals, building materials, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine and other fields. It is used as raw material, cleaning agent and detergent for manufacturing other chemicals. It is also used in photographic technology and analysis. Sodium carbonate solution is one of the main raw materials of homopolymerization production line. The concentration of sodium carbonate solution directly affects the reaction of homopolymerization production line. During the preparation process of sodium carbonate solution, a certain amount of desalted water is generally added to the sodium carbonate dissolving tank, and then sodium carbonate is added to the dissolving tank. After the feed pump circulates itself, the stirring of the agitator promotes the dissolution of sodium carbonate. The dissolved sodium carbonate solution is transported to the sodium carbonate storage tank through the pre-pump filter and the feed pump precision filter. The sodium carbonate solution in the sodium carbonate storage tank is circulated and transported through the feed pump production line.
