The invention relates to an active coke regeneration system and method. The active coke regeneration system comprises a regeneration box, a catalytic combustion device, a desorption regeneration fan and a cooling device, wherein the regeneration box, the desorption regeneration fan and the catalytic combustion device are sequentially connected through pipelines to form a closed circulation loop; the catalytic combustion device comprises a heat exchange chamber, a catalytic combustion chamber and an electric heating chamber, and a circulating passage is arranged among the heat exchange chamber, the catalytic combustion chamber and the electric heating chamber. The active coke regeneration system has the advantages that (1) active coke is heated and regenerated in the regeneration box, combination gas which is separated out enters the catalytic combustion device, is further purified and separated in the catalytic combustion device, and is subjected to catalytic combustion, and hot gas generated by combustion goes back into the regeneration box to heat and regenerate the active coke, thus realizing cycle operation, high resource use ratio, simple structure and high work efficiency; (2) heating is performed by adopting an electric heating way, thus being more energy-saving and environment-friendly and realizing more accurate temperature control.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to an active coke regeneration system and method. Background technique [0002] Activated coke is a granular material with dual properties of adsorbent and catalyst developed from lignite as the main raw material. Activated coke has the characteristics of activated carbon, and at the same time overcomes the disadvantages of high price, low mechanical strength and easy crushing of activated carbon. [0003] Activated coke filtration and adsorption treatment of wastewater or sewage is a new wastewater or sewage treatment method. The activated coke filtration and adsorption method is used to pretreat the water in polluted urban water sources to remove pollutants, fungi, smell, chroma, etc. in the water, and the treated water quality reaches the first-class water quality standard. [0004] Activated coke after sewage and wastewater treatment needs to be regenerated by...
