Description

Self-cleaning activated carbon filter unit

technical field

The utility model relates to the technical field of regeneration of filter materials in filters.

Background technique

Activated carbon has a loose and porous structure, and its outer and inner surfaces have strong adsorption. However, after a period of use, the capillary pores of activated carbon will be filled with various dirt, become saturated and lose its purification ability.

The expired activated carbon, after pickling, alkali washing, water washing and drying, can remove most of the insoluble inorganic salts, oil and other impurities in the gaps, so that it can be activated again.

As the country attaches great importance to the ecological environment, activated carbon filters are more and more widely used in the field of water treatment, but the production cost of activated carbon is high and the price is expensive, which brings great economic pressure to the units using activated carbon filters. At present, the existing activated carbon filters, when the activated carbon is saturated, all need to be transported back to the relevant manufacturers for regeneration, resulting in high regeneration costs and difficulties in disassembly and transportation.

Patent No. 202951303U Chinese invention patent discloses an ultrasonic on-line regenerated activated carbon filter. This invention uses ultrasonic waves to regenerate activated carbon. Uniform ultrasonic vibration is applied to the activated carbon during water washing. After washing, steam circulation is used to take away organic volatiles. In practical applications, since the organic substances adsorbed by activated carbon cannot be removed by water washing, acid washing or alkali washing is required to further remove these organic substances and inorganic salts.

The filter element body can be isolated separately, and the inorganic salt and some organic matter on the filter element body can be dissolved and taken out by hydrochloric acid solution or sodium hydroxide solution; 2. Drying The dry device can promote the volatilization of hydrochloric acid solution and organic matter remaining on the filter body, saving the amount of water used to clean the filter body; and further improving the removal effect of organic matter; 3. When the regenerated filter body is rinsed with clean water, The ph sensor can measure the ph value of the flushing water. When the ph reaches the ph value of the clean water itself, it can remind the user that the water coming out of the filter body has reached a normal state; The device can accelerate the desorption of inorganic salts and organic matter through ultrasonic vibration; further improve the activation rate of activated carbon; It is subject to the service temperature of -180°C-+250°C, and it is non-sticky, and it is not easy to generate dirt after long-term use.
