Description
Technical field
The present invention relates to flue gas pollutant sulfur dioxide removal field, more particularly to a kind of powder activity coke Two-way Cycle fluidisation
Bed desulphurization system and method.
Background technology
Active coke desulphurizing is a kind of flue gas desulfurization technique of resourcebility, while to pollutants such as the heavy metals in flue gas
There is apparent cooperation-removal to act on.Active coke desulphurizing technology currently on the market is mainly using moving bed absorption-heating regeneration work
Skill route, moving bed absorbing process use the amorphous pellets activated coke of higher mechanical strength, and shape is generally Φ 5-9mm diameters
Column, column activated coke inside diffusional resistance cause greatly utilization rate of inner surface low;The broken abrasion of transmission process causes mechanical damage
Losing increases operating cost;Column complex forming technology increases activated coke cost.Powder activity coke fluidised bed adsorption desulfurization is one
Kind novel active coke sulfur removal technology route, process avoids the mechanical loss that column-shaped active carbon abrasion generates, Powdered Activated Carbons
Cost is relatively low while surface utilisation opposed cylinder activated carbon improves.Powder activity coke fluid-bed sweetening technology is normally based on often
The circulating fluidized bed dry sulfur removal technology reactor types of rule, using activated coke as the sulfur removal technology of desulfurizing agent.It is recycled in activated coke
During fluid-bed sweetening, function according to the property of activated coke and in systems can be divided into fresh activity coke, cycle it is burnt and
Weary coke, wherein fresh activity coke refer to fresh preparation or by activated coke of the regeneration with fresh adsorption capacity;The burnt fingering of cycle
Enter system, at least undergo in a tower and adsorb, be captured and separate into deduster, to send desulfurizing tower back to and continue to adsorb
Activated coke;Weary coke, which refers at least to undergo in a tower, to be adsorbed, and transmitting system is wanted to carry out regenerated activated coke.Regular circulation fluidizes
In bed adsorption form, there are problems that cycle is burnt and weary coke can not be efficiently separated.As a kind of fluidization of patent of invention is lived
Property charcoal combined desulfurization and denitrification process, application number 201010189427.2, disclose fresh activity coke and cycle coke send to desulfurization
Tower bottom is carried along into deduster by rising flue gas, and the activated coke detached through deduster, a part, which sends back to continue cycling through in tower, to be made
With a part of discharge system is regenerated as weary coke.Under this form, it is weary it is burnt be that mix can not with cycle coke
Separation, there is the activated coke not being utilized effectively in weary coke, reduce the effective Sulfur capacity of entirety of activated coke.
Invention content
The above problem of moving bed process and fluidized-bed process in desulfurization technology is adsorbed for existing activated coke, the present invention carries
For a kind of burnt double-circulating fluid bed desulphurization system of powder activity and method, which adsorbed using powdered activated coke as desulfurization
