The invention relates to a preparation method of soy protein isolate with low sodium, high calcium and low viscosity, and belongs to a processing technique of vegetable protein. The method comprises the following steps: (1) performing leaching treatment on degreased bean powder in an alkaline solution; (2) centrifuging mixed liquor; (3) adding HCl to the mixed liquor, regulating pH to be 4.5, and performing acid precipitation; (4) centrifuging the obtained curds once again, draining supernatant, and cleaning precipitate with water three times so as to obtain acid precipitation curds; and (5) sterilizing the acid precipitation curds, and drying the sterilized acid precipitation curds so as to obtain finished products. The method has the advantages that the technology is simple, the operation is safe, measurement and control are easy and the cost is low; the finished soy protein isolate products have the characteristics of low sodium, high calcium and low viscosity.

The invention discloses a method for desulfurizing low-concentration flue gas from hydropower silicon smelting. The method includes the following steps: 1) preparation of absorption slurry: thoroughly mix the desulfurization adsorbent ground to 325-400 mesh with water to obtain the absorption slurry; 2) Absorption of acid gas: When the flue gas from hydropower silicon smelting enters the desulfurization system, the absorption slurry and the flue gas are fully contacted in the desulfurization tower, so that the acid gas and particles in the flue gas are absorbed by the absorption slurry; 3) Flue gas Emissions: detection of outlet SO 2 If the emission concentration meets the requirements, it can be discharged, and if it does not meet the requirements, it can be returned to the desulfurization system for treatment, and the absorbed absorption slurry is filtered, and the filtrate is returned to step (2) as the absorption liquid, and the filter residue is sold as a by-product. The present invention uses limestone and other desulfurization adsorbents mixed with water to make absorption slurry, and the flue gas enters the desulfurization system and fully contacts with the slurry to remove acid gas and particulate matter, so that the emission concentration of sulfur dioxide in the flue gas is reduced to 80mg / Nm 3 Below, effectively realize green and environment-friendly production.

The invention relates to the technical field of building materials, in particular to a calcium silicate hydrate early strength agent and a preparation method thereof. The preparation method of calcium silicate hydrate early strength agent comprises the following preparation steps: 1) preparation of calcium liquid; 2) preparation of silicon liquid with silicate as silicon source; 3) synthesis of calcium silicate hydrate: polyoxo The dispersant solution compounded with ethylene (5) nonylphenyl ether and cyclohexane was placed in a shear stirring mixing device, kept stirring at room temperature, and added the prepared calcium liquid and silicon liquid, and then used alkaline The solution adjusts the pH value of the mixed solution, maintains constant temperature and stirs, and obtains white calcium silicate hydrate gel; washes the obtained white calcium silicate hydrate gel by centrifugation, and then dries in a vacuum drying oven to obtain hydrated silicic acid Calcium early strength agent. After the calcium silicate hydrate accelerator prepared by the above preparation method is mixed into cement, it can promote the hydration of cement, significantly shorten the setting time of cement, and improve its early strength at the same time, which has important practical application value in the field of construction.

The invention relates to a method for preparing milk powder for promoting children's height development and its formula, comprising: step a, sterilizing whey powder outer packaging, various auxiliary materials outer packaging, mixers, and packaging machines; step b, passing the first Put whey powder into the mixer through the feed inlet, put milk calcium into the mixer through the second feed inlet, start the stirring paddle to mix evenly to form the first mixture; step c, the central control unit determines the first mixture When the calcium ion content meets the standard, add the weighed hydrolyzed egg yolk powder, colostrum basic protein, whey protein powder, N-acetylneuraminic acid, lactoferrin, milk Colostrum, docosahexaenoic acid, etc., and start the stirring paddle to mix evenly to form the second mixture; step d, transport the second mixture to the packaging machine through the powder delivery pipe for sub-packaging; thereby effectively increasing the calcium content of milk powder Determine the optimal water temperature while determining the ion content to maximize the absorption of the nutrients in the milk powder that promote height development.
