Embodiment 1
[0015] A kind of sludge stripping method of circulating cooling water system, weigh 10 kilograms of sodium dodecylbenzenesulfonate, 5 kilograms of triethanolamine, 5 kilograms of polydimethylsiloxane, 15 kilograms of sodium polyacrylate, mix evenly, add 65 kilograms Stir and dissolve the pure water to obtain the sludge stripping aid; then keep the cooling water in the circulating cooling water system at the highest level, and add the sludge stripping aid to the cooling water according to the ratio of 400-500mg of the sludge stripping aid per liter of cooling water, Let the circulating water circulate normally for about 20-40 minutes; then add 2000-3000 mg of 13% (weight) sodium hypochlorite solution per liter of cooling water, and add 13% sodium hypochlorite solution to the cooling water in normal circulation, every Check the turbidity of the circulating water every 30 minutes. When the turbidity reaches the peak value, the turbidity rises by about 15-20 times. The circulation ...
Embodiment 2
[0017] It is basically the same as Example 1, except that 8 kilograms of sodium dodecylbenzenesulfonate, 4 kilograms of triethanolamine, 6 kilograms of polydimethylsiloxane, 18 kilograms of sodium polyacrylate, and 64 kilograms of purified water.
Embodiment 3
[0019] Substantially the same as Example 1, the only difference is 12 kilograms of sodium dodecylbenzenesulfonate, 6 kilograms of triethanolamine, 4 kilograms of polydimethylsiloxane, 12 kilograms of sodium polyacrylate, 66 kilograms of purified water, 35% ( weight) hydrogen peroxide instead of 13% sodium hypochlorite solution.
