Description

Technical Field

[0001] This utility model relates to the field of activated carbon regeneration technology, and in particular to a device for regenerating powdered activated carbon. Background Technology

[0002] Powdered activated carbon (PAC) is a finely powdered adsorbent material made from various carbon-containing raw materials (such as wood, coconut shells, and coal) through high-temperature carbonization and activation. It possesses a large specific surface area and a well-developed pore structure, which makes PAC excellent at removing organic pollutants, odors, colors, and other trace contaminants from water.

[0003] Powdered activated carbon is an adsorbent material with excellent adsorption performance. However, directly discarding used powdered activated carbon can easily lead to resource waste and increase operating costs. When regenerating activated carbon, thermal regeneration is usually used. However, excessively high temperatures during thermal regeneration can cause some microporous structures to collapse or burn out, thereby reducing its specific surface area and adsorption capacity. Furthermore, chemical regeneration makes it difficult to separate the soaked activated carbon from impurities, thus reducing the processing efficiency of powdered activated carbon. Utility Model Content

[0004] The purpose of this invention is to address the problems in the existing technology where powdered activated carbon is an adsorbent material with excellent adsorption performance, but directly discarding it after use easily leads to resource waste and increases operating costs. While thermal regeneration is commonly used for activated carbon regeneration, excessively high temperatures can cause some microporous structures to collapse or burn away, reducing its specific surface area and adsorption capacity. Furthermore, chemical regeneration makes it difficult to separate the soaked activated carbon from impurities, thus reducing the efficiency of powdered activated carbon treatment.

The powdered activated carbon to be processed is placed inside the filter box 115, and the filter box 115 is embedded inside the barrel 1. Chemical reagents such as hydrochloric acid, sulfuric acid, and sodium hydroxide solution are injected into the barrel 1. The pollutants on the powdered activated carbon are converted and separated by the chemical reagents. Multiple filter holes 118 are opened on the outer surface of the filter box 115 to facilitate the entry of chemical reagents into the interior of the filter box 115 and mixing with the powdered activated carbon. A rectangular groove 116 is opened at the lower end of the filter box 115. A filter screen plate 117 is movably embedded inside the rectangular groove 116. The filter screen plate 117 can separate the powdered activated carbon from the dissolved precipitated impurities, thereby improving the separation effect between the powdered activated carbon and impurities.

[0047] In this embodiment, the powdered activated carbon to be processed is placed inside the filter box 115. The limiting plate 114, which is fixedly installed on the outer surface of the filter box 115, is embedded inside the barrel 1 and connected to the positioning plate 112. The barrel 1 contains chemical reagents, which enter through the filter holes 118 on the outer surface of the filter box 115 and mix with the powdered activated carbon inside. The chemical reagents decompose and transform the pollutants on the powdered activated carbon, thus regenerating the powdered activated carbon. A rectangular groove 116 is provided at the lower end of the filter box 115. A filter screen plate 117 is movably embedded inside the rectangular groove 116. The filter screen plate 117 can separate the powdered activated carbon from the dissolved precipitated impurities, thereby improving the separation effect between the powdered activated carbon and the impurities.
