Say the characteristics of ceramic filter plate first.

How to clean ceramic filter plate is better?

Ceramic filter plate has the characteristics of corrosion resistance, high temperature resistance, high mechanical strength, insoluble harmful substances, no secondary pollution and so on. Under the action of fluid pressure, the microhole is not deformed, easy to clean and regeneration, long service life. Can replace cotton, silk, plastic, silk screen, asbestos cotton and other filtering materials, widely used in solid-liquid separation, gas-liquid separation, powder transportation, oil-water separation and brewing industry separation.

Ceramic filter plate has the following characteristics:

1. High temperature resistance: can withstand the high temperature of 480℃ or so.

2. Simple cleaning: single-layer filter material is characterized by simple cleaning, especially suitable for backwashing.

3. Corrosion resistance: stainless steel raw material itself has high corrosion resistance and wear resistance.

4. High strength: high quality materials have higher pressure resistance and can withstand greater working strength.

5. Filtration effect is very stable: select high-quality raw materials in the production process, not easy to deformation in the use process.

Particles may block the micropores on the surface of the ceramic filter plate, or a small amount of fine particles may enter the micropores inside the ceramic filter plate, causing blockage and affecting productivity, which should be cleaned up.

Ensure the recoil pressure of each cycle, used to recoil from the inside of the ceramic filter plate to wash away the fine particles or particles on the surface.

Ensure chemical and physical cleaning during downtime. First, ensure the time and quality of each cleaning, ensure that cleaning in place. When the ceramic filter plate is seriously blocked, do not stop cleaning the machine to ensure that the ceramic filter plate regeneration.

Choose suitable scour and chemical scour, can make the fine grain that washes not easily produces chemical reaction, achieve refined goal thereby. Then combined with cyclic backwash, the fine particles are washed away, and different chemical detergents are selected for different grout to achieve particle refinement.

According to the characteristics of different slurry, ultrasonic equipment is reasonably selected, and ultrasonic cleaning is used for physical cleaning. The power-frequency electrical energy of the power supply is converted into a high-frequency electrical signal, which is transmitted to the transducer through a high-frequency cable. Ultrasonic transducer can convert high frequency electric energy into powerful ultrasonic wave and send it outwards. Vibration in the aqueous solution of ultrasonic water tank produces powerful shock wave, which will be affected by dirt on the surface of ceramic filter plate. Because ultrasonic attenuation in aqueous solution is very small, it is possible to clean surfaces (including crevices and holes) of objects immersed in liquid and ceramic filter plates of physically immersed surfaces. The general temperature is 20-50℃, aqueous solution is better. During the cleaning process, the spindle speed will slow down. After a period of time, please adjust the spindle speed or use automatic frequency ultrasonic equipment to achieve each cleaning point. If there is sticky dirt on the surface of the ceramic filter plate, a high frequency ultrasonic transducer can be used.
