The technical issues of being greatly reduced.By the way that temperature drop control in the numberical range less than 30%, can be avoided this significantly
Kind technical problem, it is ensured that the rate of recovery is allowed to be in a higher level.
5. being heated to the tail gas given off from the active carbon production equipment by heating device, on the one hand
Can to avoid mentioning in the 4th point in tail gas transmission process, because of technical problem caused by temperature decrease, can also improve into
The temperature for entering the tail gas into absorber, so as to which further moist Activated Carbon Production raw material is dried,
Promote subsequently directly obtain the preferably dry Activated Carbon Production raw material for being adsorbed with chemical activating agent.
It, can be more efficiently to Activated Carbon Production original 6. the exhaust temperature being passed into the absorber is 60-240 DEG C
Material is dried, and promotes subsequently directly obtain the preferably dry Activated Carbon Production raw material for being adsorbed with chemical activating agent.
7. being passed into 100-230 DEG C of the exhaust temperature in the absorber, the above-mentioned 4th can be more effectively avoided
Technical problem in point can also more effectively be dried Activated Carbon Production raw material, promote subsequently directly obtain
The preferably dry Activated Carbon Production raw material for being adsorbed with the pollutant that can be used for Activated Carbon Production.
8. the initial temperature of the tail gas is 30-90 DEG C, the tail gas heating is heated up at least by the heating device
20%, it can be effectively prevented from the technical problem in above-mentioned 4th point as a kind of more preferably embodiment, it can also be more
Effectively Activated Carbon Production raw material is dried, promotes subsequently directly obtain being adsorbed with including institute for preferably drying
State the Activated Carbon Production raw material for the pollutant that can be used for Activated Carbon Production.
9. the recovery system of the present invention, including：Absorber is equipped with Activated Carbon Production raw material, has absorber gas access
With absorber gas vent, the absorber gas access is connected to the offgas outlet of active carbon production equipment, for making activity
Charcoal raw materials for production are contacted with the tail gas given off in active carbon production equipment.This design can improve to tail gas in can
While the rate of recovery for the pollutant of Activated Carbon Production, equipment is greatly simplified, reduces process costs, and environmental protection can be reached
Effect.
10. the absorber includes absorber ontology, the absorber gas access and the absorber gas vent are set
In on the absorber ontology, inlet port and outlet port are additionally provided on the absorber ontology；Further include with conveyer belt
Belt conveyer, be set to the absorber body interior；Wherein, the belt conveyer for receive from the feed inlet into
The Activated Carbon Production raw material entered, and the absorber is discharged in the Activated Carbon Production feedstock transportation to the discharge outlet
Ontology, the Activated Carbon Production raw material are contacted during conveying with the tail gas of entrance, and to the tail gas
Flowing is obstructed.It can be designed so that pollutant described in the tail gas being passed on the Activated Carbon Production raw material above
It is intercepted and is adsorbed by the Activated Carbon Production raw material.
11. the recovery system of the present invention, wherein be located at the thickness of the Activated Carbon Production raw material on the conveyer belt
For：100-1000mm；Flow velocity into the tail gas of the absorber is：0.1-0.8m/s；The material is on the conveyor belt
Residence time is：1-5h.It not only can be effectively so that the Activated Carbon Production raw material be to the pollutant in the tail gas
It is obstructed and is adsorbed, and more Activated Carbon Production raw material can be made to be adsorbed with the pollutant, obtain more having
