High-temperature salt inhibitor for back-spraying evaporation system of high-salinity wastewater quench tower

The invention discloses a high-temperature salt inhibitor for a back-spraying evaporation system of a high-salinity wastewater quench tower. The high-temperature salt inhibitor comprises citric acid,EDTA disodium, monopotassium phosphate, nitrilotriacetic acid trisodium salt, sodium dodecyl benzene sulfonate, hydrolyzed polymaleic anhydride and water. The production process of the high-temperature salt inhibitor for the back-spraying evaporation system of the high-salinity wastewater quench tower comprises the following steps: step one, adding proportioned citric acid, disodium EDTA, monopotassium phosphate, nitrilotriacetic acid trisodium salt, sodium dodecyl benzene sulfonate, hydrolyzed polymaleic anhydride and water into a stirring container, and conducting mixing to obtain a mixed solution; 2, adjusting the pH value, namely adding caustic soda or hydrochloric acid into the stirring container, and adjusting the pH value of the mixed solution in the stirring container; 3, conducting heating in a water bath
