Description

Technical Field

[0001] The utility model relates to waste gas treatment equipment, in particular to waste gas treatment equipment for aspartic acid chelated calcium magnesium production, belonging to the technical field of aspartic acid. Background Art

[0002] Aspartic acid is a white crystal or crystalline powder with a slightly sour taste. It is slightly soluble in water, insoluble in ethanol and ether, and becomes clear after color change. It has good structural stability. Aspartic acid is used in the field of plant nutrition. On the one hand, it is the smallest molecule that constitutes protein and is easily absorbed and utilized by crops, which is green and environmentally friendly. On the other hand, aspartic acid is a natural chelating agent. Compared with inorganic medium-element fertilizers, amino acid chelated medium-element fertilizers are not easily fixed in the soil and do not reduce fertilizer efficiency.

[0003] Aspartic acid has a weak chelating ability. Calcium aspartate and magnesium aspartate are products obtained by mixing, homogenizing, grinding, chelating, and drying calcium compounds or magnesium compounds with aspartic acid. Due to the weak chelating ability of aspartic acid, calcium and magnesium aspartate chelate production requires adding calcium hydroxide or magnesium hydroxide to a supersaturated aspartic acid solution, stirring to obtain a turbid liquid, and then adjusting the pH value to 5-7. The solution is then reacted in a liquid nitrogen environment at -196°C for 80 minutes, and then thawed at 20°C-80°C. Ethanol is then added and stirred to obtain a precipitate, which is then extracted, dried, and crushed to obtain calcium and magnesium aspartate.

[0004] During this period, the huge energy generated by aspartic acid in a liquid nitrogen environment at minus 196°C and a large temperature difference between 20°C and 80°C is used to promote chemical reactions. However, the violent chemical reaction causes a turbid liquid with a pH value of 5-7 to produce a large amount of acidic waste gas during the reaction. If it is directly discharged into the air without treatment, it will pollute the air. Utility Model Content
