Device for regenerating powdered activated carbon

Abstract

The invention discloses a device for regenerating powdered activated carbon. The device has a square plane shape, and is provided with a water inlet area, an electrochemical regeneration area, a flow guiding area, a water outlet area, a precipitation separation area and a storage area from the center to the periphery, a water and carbon inlet pipe is arranged below the water inlet area, and electrolyte and saturated powdered activated carbon to be processed enter the water inlet area through the water and carbon inlet pipe and pass through the electrochemical regeneration area, the flow guiding area, the water outlet area, the precipitation separation area and the storage area sequentially; after the regeneration process is finished, produced water is discharged through a main water drain pipe, and regenerated powdered activated carbon is discharged through a regenerated carbon discharge pipe; a boron doped diamond positive pole and a stainless steel negative pole are arranged in the electrochemical regeneration area; a perforated aerator pipe, a mud bucket and the regenerated carbon discharge pipe are arranged in the storage area. According to the device, the regeneration and the precipitation separation of powdered activated carbon are integrated, and the regeneration of powdered activated carbon is realized by intermittent operation, and the utilization ration of activated carbon is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a device for regenerating powdered activated carbon. Background technique [0002] Activated carbon is a kind of porous material, which is widely used in the field of water treatment because of its large specific surface area and strong adsorption capacity. However, the adsorption capacity of activated carbon is not eternal. With long-term adsorption, the pores will be blocked and the adsorbate will be saturated, and the adsorption capacity of activated carbon will gradually decrease until it is saturated. Therefore, the regeneration of saturated activated carbon is an inevitable requirement. [0003] In the existing technical solutions, there are few regeneration technologies for powdered activated carbon, mainly granular activated carbon regeneration technology, and most of them are heating regeneration methods, the regeneration efficiency is relatively low, and the ene...

However, the adsorption capacity of activated carbon is not eternal. With long-term adsorption, the pores will be blocked and the adsorbate will be saturated, and the adsorption capacity of activated carbon will gradually decrease until it is saturated. Therefore, the regeneration of saturated activated carbon is an inevitable requirement.

[0003] In the existing technical solutions, there are few regeneration technologies for powdered activated carbon, mainly granular activated carbon regeneration technology, and most of them are heating regeneration methods, the regeneration efficiency is relatively low, and the energy consumption is high
