Production method of high-concentration naphthalene water reducer and solid-liquid separation device based on method
The invention relates to a production method of a high-concentration naphthalene water reducer and a solid-liquid separation device based on the method. The method sequentially comprises five procedures including sulfonation, hydrolysis, condensation, neutralization and solid-liquid separation, wherein neutralization is performed twice, a sodium hydroxide solution is added to a condensed naphthalene mother liquid during neutralization for the first time, magnesium hydroxide, magnesium oxide or quick lime powder is added to the naphthalene mother liquid during neutralization for the second time, two times of neutralization are adopted, the good neutralization effect can be guaranteed, meanwhile, the content of sodium sulfate in a finished product can be effectively reduced, and a pipeline is prevented from being blocked. The solid-liquid separation device can finish separation twice and finish solid waste washing after separation, the filtering effect is good, and collected solid waste can be treated and is convenient to recover.
