It is capable, thus heat and mass transfer direction is opposite, when promoting mass transport process using carrier gas, usually promote it is inefficient, and
Easily cause secondary pollution；Conventional heating methods also exist living after larger energy expenditure, activated carbon proportion of goods damageds height and regeneration simultaneously
The property low problem of carbon activity recovery rate.
Traditional active carbon regenerating technology has following common defect：The adsorption capacity of activated carbon has bright after regeneration
It is aobvious to decline；Regenerative process forms new secondary pollution；Regeneration need it is higher to equipment and experiment condition requirement, in regenerative process
Charcoal loss is big, it is impossible to realize in-situ regeneration.Accordingly, it would be desirable to be improved to traditional active carbon regenerating technology, solve or delay
Solve problems present on regeneration techniques.
Microwave radiation regenerated carbon refers to make organic matter desorption, charing, activation by high temperature, so as to recover its energy of adsorption
A kind of method of power.Microwave refers to the electromagnetic radiation being located in electromagnetic spectrum between far infrared and radio wave.Microwave radiation mistake
Cheng Zhong, the absorption microwave energy that organic pollution can not continue is to reach the temperature needed for degraded, and activated carbon can effectively absorb
Microwave energy makes temperature reach more than 1000 DEG C.Organic pollution overcomes Van der Waals force to attract to start desorption under microwave action,
With the aggregation of microwave energy, under pyrogenicity and nonthermal effect collective effect, a part of combustion decomposition of organic pollution is released
Carbon dioxide, another part is then carbonized.The factor for influenceing micro wave regeneration activated carbon is amounts of activated carbon, microwave power, microwave successively
Exposure time and carrier gas linear speed etc..Microwave heating can be such that activated carbon further activates, and improve adsorption capacity.In this way again
The time of raw useless charcoal is short, and energy consumption is low, simple in equipment, with preferable application prospect.
In view of the heat characteristic of microwave and its increasing application in all fields, many researchers look for another way,
It is relatively weak to activated carbon progress regeneration Research foundation as thermal source using microwave at present based on hot recycling is theoretical,
