AI Technical Summary

Problems solved by technology

However, traditional activated carbon regeneration technologies such as heating regeneration, chemical solvent regeneration and biological regeneration usually have the following defects: (1) The loss of activated carbon is often large during the regeneration process; (2) The adsorption capacity of activated carbon decreases significantly after regeneration; ( 3) Secondary pollution caused during regeneration; (4) Long time required for regeneration

However, emerging activated carbon regeneration technologies such as electrochemical regeneration, supercritical fluid regeneration, catalytic wet oxidation, ultrasonic regeneration, etc., are difficult to realize industrial application due to the low utilization rate of regeneration energy, complicated operation, and high cost.

[0004] Existing technologies and devices, such as ZL200720093194.X, named gas-fired granular activated carbon regeneration rotary kiln, and ZL200520047681.3, named electric direct heating rotary furnace (internal heating type) activated carbon regeneration device, which has the advantages of simple structure and easy damage Less parts, high thermal efficiency, high degree of automation, etc., the disadvantage is that it will produce secondary pollution, which will affect the popularization and application

[0005] Existing technologies and devices, such as CN101073766A, are called ultrasonic desorption activated carbon regeneration technology. The advantages of this technology are low energy consumption and low cost. The disadvantage is that it is only effective for the regeneration of activated carbon physical adsorption, and its industrialization application is limited.

[0006] Existing technologies and devices, such as ZL200410020410.9, named regeneration method of activated carbon that decomposes and treats organic matter in wastewater by microwave irradiation, has advantages of low energy consumption, no secondary pollution, short regeneration time, etc., and disadvantages of energy dissipation surface Large, limited by the amplification of microwave energy, affecting industrial amplification

[0007] In summary, the existing activated carbon regeneration technology and devices maturely applied in industrial production are still mainly high-temperature heating regeneration, which generally causes secondary pollution and other problems; while the emerging activated carbon regeneration technology and devices are still in the experimental research stage, industrial scale-up There are certain technical bottlenecks
