ISO9001 Air Filter can be regenerated and cleaned according to the pollution conditions and the chemical properties of the contaminants combined with the physicochemical properties of titanium. The primary choice of physical methods: clean liquid recoil, clean gas backflushing and ultrasonic cleaning. Chemical methods are the primary choice: dilute acid, dilute alkali, oxidant, external active agent, enzyme and other cleaning agents. The above various methods can also be used interchangeably. According to several common application conditions, the cleaning method is as follows.
For decarbonization filtration in the pharmaceutical and chemical industries, backflushing, backflushing and ultrasonic cleaning are often used. In the water industry, most of the water-repellent salts and oxides are trapped in the outer surface of the filter. Generally, 5% nitric acid is used for immersion, and the cleaning effect can be achieved without ultrasonic cleaning.
The original liquid filtration, combined with the chemical nature of the contaminants, should be cleaned by the following methods: Alkaline washing: soaking the pure solution with 3-5 percent sodium hydroxide to soak for 30-60 minutes, the temperature is about 40 degrees, in the ultrasonic cleaning machine in. After soaking, use filtered deionized water or a needle to smear to neutral with water and measure the conductivity. Dry with pure air ≥ 0.4MPa pressure.
Pickling maintenance: How to clean the Air Filter Element For Pulse Jet with a 5 percent nitric acid solution for more than 8 hours, the temperature is about 40 degrees. In an ultrasonic cleaner. After soaking, use filtered deionized water or a needle to wash the water to neutral, side conductivity. Dry with pure air ≥ 0.4MPa pressure.
Organic pollution can be combined with external active agents to clean, cell debris contamination system combined with enzyme cleaning is more ambitious (food and beverage can be washed with high concentration of citric acid). The above methods can be used alone or in combination with each other. If available, combine with an ultrasonic cleaner. Note: Always backflush online (cleaning with pure compressed air or filtered stock solution or clean water backflush), you can fear the number of times to clean with the above method.
