Anti-scaling method for petroleum cooling tower

[0009] The principles and features of the present invention will be described below, and the examples given are only used to explain the present invention, not to limit the scope of the present invention.

[0010] An anti-scaling method for petroleum cooling towers. The anti-scaling agent and the cross-linking agent are mixed in a ratio of 1:1—1:2, heat treated at 20-65℃, and then stirred for 68-72 hours to prevent the scale The agent is cross-linked with the cross-linking agent to form ester bonds, amide bonds, and imide bonds, and then transported to the pulverizer to be crushed into particles of 50 μm to about 4000 μm. The scale inhibitor is selected from polymers, oligomers, copolymers, One or a mixture of two or more of low molecular weight carboxylates, acrylates, sulfates, and sulfonates. The crosslinking agent is a polyhydric alcohol selected from glycerin, 1,6-hexanediol, pentaerythritol and or Mixtures thereof, mixtures of polyols and polyamines, polyamines, amino alcohols
