1. Set a pre-cooler in the ultra-pure water equipment to make the evaporation temperature of the tube surface of the evaporator below 40 ℃. At the same time, a large amount of water, intensive water distributor is used to ensure that the surface of the condenser tube is covered by water film at all times and there is no drying point.
2. Pre-film anti-scaling treatment shall be carried out during the manufacture of ultra-pure water equipment. It can effectively prevent fouling crystals from adhering to the surface of the copper tube, reduce the possibility of fouling in the evaporator, and prolong the structural cycle of the evaporator and the air cooler.
3. A small amount of continuous drainage device is adopted to control the concentration multiple of calcium ions in the cooling circulating water of ultra-pure water equipment within a certain range, thus effectively preventing the precipitation of scale.
The internal scale of ultra-pure water equipment seems inconspicuous, but it can cause equipment blockage and damage, and also affect the production quality. Therefore, everyone must pay attention to daily maintenance and cleaning.
