Production system of naphthalene series industrial water reducer
The invention discloses a production system of naphthalene series industrial water reducer. The production system comprises an industrial liquid naphthalene storage tank, a crystallization tower, a distillation tower, an acidification tower, a hydrolysis tower, a first reaction tower, a second reaction tower, a condensation reaction tower, a pH adjustment tower, a third reaction tower, a centrifugal dehydration tower, a drying tower, a high-grade finished product storage tank, a dilution reaction tower, a primary product storage tank, a purification reaction tower, a middle product storage tank, a water tank, a first dosing facility, a second dosing facility, and a purification facility. The concentration of the water reducer produced by the provided system is high and can reach 99.9% or more; the gas content is less than 2%, the bleeding rate is less than 0.5%, the difference between initial setting times is 19, the difference between final setting times is 32, and the alkali content is less than 0.5%. Reactants such as allyl alcohol polyoxyethylene ether, maleic anhydride, polypropyl sodium sulfonate, methacrylic acid, and the like are added into the second reaction tower. Calcium carbonate and sodium hydroxide are added into the pH adjustment tower.
