Embodiment 1
[0012] Taking the preparation of 12 tons of antiscalant liquid as an example, the mass of solid matter sodium dodecylbenzene sulfonate is 0.06 tons, the mass of sodium stearate is 0.036 tons, the mass of sodium lignosulfonate is 0.12 tons, and the mass of sodium polyacrylate is 0.18 tons. Mix and stir evenly, the mass concentration of sodium dodecylbenzenesulfonate in the prepared scale inhibitor solution is 0.5%, the mass concentration of sodium stearate is 0.3%, the mass concentration of sodium lignosulfonate is 1%, sodium polyacrylate The mass concentration is 1.5%.
[0013] After heating the antiscalant to a temperature of 20°C, add it into the pipeline of phosphoric acid equipment; the amount of antiscalant added is 0.05% of that of wet-process phosphoric acid.
Embodiment 2
[0015] Taking the preparation of 12 tons of antiscaling liquid as an example, the mass of solid matter sodium dodecylbenzene sulfonate is 0.09 tons, the mass of sodium stearate is 0.066 tons, the mass of sodium lignosulfonate is 0.21 tons, and the mass of sodium polyacrylate is 0.21 tons. Mix and stir evenly, the mass concentration of sodium dodecylbenzenesulfonate in the prepared scale inhibitor solution is 0.75%, the mass concentration of sodium stearate is 0.55%, the mass concentration of sodium lignosulfonate is 1.75%, sodium polyacrylate The mass concentration is 1.75%.
[0016] After heating the antiscalant to a temperature of 50°C, add it into the pipeline of phosphoric acid equipment; the amount of antiscalant added is 0.04% of that of wet-process phosphoric acid.
Embodiment 3
[0018] Taking the preparation of 10 tons of antiscalant liquid as an example, the quality of solid matter sodium dodecylbenzene sulfonate is 0.1 tons, the quality of sodium stearate is 0.08 tons, the quality of sodium lignosulfonate is 0.25 tons, and the quality of sodium polyacrylate is 0.2 tons. Add water, mix and stir evenly, and the mass concentration of sodium dodecylbenzenesulfonate in the prepared antiscalant solution is 1.0%, the mass concentration of sodium stearate is 0.8%, the mass concentration of sodium lignosulfonate is 2.5%, and the mass concentration of polyacrylic acid The sodium mass concentration is 2.0%.
[0019] After heating the antiscalant to a temperature of 80°C, add it into the pipeline of phosphoric acid equipment; the amount of antiscalant added is 0.03% of that of wet-process phosphoric acid.
