Titanium rod filter regeneration (cleaning) process
2014-09-24
Titanium rod filter regeneration process, physical regeneration process of this technology is suitable for the filtration medium particles less impurity, titanium filter clogging to a lesser degree.Such as: ozone disinfection filtration;Air filter, such as: 1, the back: with pure water (deionized water) reverse back 15 min, the back pressure is less than 0.4 Mpa, or with clean air (steam) counter blowing, blowing pressure is less than 0.4 Mpa.2, ultrasonic cleaning, the titanium rods into the ultrasonic cleaning the pool, cleaning out after 60 min, 15 min is washed with deionized water or distilled water, after drying.Second, the chemical treatment process in this process is suitable for the titanium filter clogging serious, filter medium ingredients are complex (such as decarburization filtration, containing protein medium filtering, medium high viscosity) 1, alkaline wash process, first of all, the new production using or holiday for a long time, then takes 1 ﹪ NaOH is used to analyze alcohol solution soak 30 min, soaked with water infiltration often before you add in the alkaline solution, after soaking washed with deionized water inside and outside two times each, every time not less than 30 min, 0.2 0.3 Mpa, hydraulic flushing after put still water without any debris (inspection), test the PH value is neutral.2 A and cleaning fluid, pickling process configuration: potassium dichromate (or sodium) 5) (oven dry), 1000 g water sulfuric acid (industrial) method to MLB, 2000: take potassium dichromate (or sodium) crystal or powder, 60-80 degrees heat water dissolved, add the sulfuric acid (94-96) to the full amount, began to add acid should be slow, and while stirring, after add to 1200 ml potassium dichromate (or sodium) completely dissolved, color change from brown to dark red, the speed can be faster, until adds.If you acid has filled is, there are not dissolved and then heated to dissolve, put cold, sealing and set aside.C, configuration, process pay attention to the following items: 1, the general cleaning fluid can remove device attached to the wall of dirt, grease and metal particle impurities, etc., and can kill microorganisms and heat source.Before immersion cleaning fluid must first will wash washing, otherwise it will precipitate fatty acids and defiled filter element.2, such as cleaning fluid in palm red to green when it indicates that the oxidation ability is abate, should not be used.3, such as acid concentration will be reduced to less than 85, decontamination ability is greatly reduced, so the prescription in the water is too.4, configuration, when cleaning fluid should be slowly adding potassium dichromate solution of sulfuric acid, while stirring.Must not be in acid water, in case of sudden heat explosion accidents.5, cleaning fluid, not with alcohol, caustic soda mixed so as to avoid explosion.6, cleaning fluid, easy to water absorption, easy to airtight save for later use.7, after the cleaning fluid configuration, when diluted twice before using, solution concentration in a 2.5 ﹪ - 3 ﹪.B, cleaning steps: 1, remove the filter element.2, flush with water for injection or filtering distilled water inside and outside wall 3 min, temperature of 60 degrees or so.3, using compressed air (note: do not allow mixed with oil and gas in the air of fog) then blow dry water droplets blowing off.4, in the cleaning fluid (by 2.5 ﹪ - 3 ﹪ concentration) soak for 15 min or so.5, both inside and outside wash three times with deionized water or distilled water, the water pressure in 0.3 0.35 Mpa, the temperature of 80 degrees, at room temperature can also be used.6, with hot steam dry element residual water directly into the steam tank, sterilization over 40 min.7, clean with less water for injection, baking temperature of 112 degrees temperature more than 1 hour.8, in the sterilization box sealing protection.Bubble point tests before 9, use every day.
