Abstract
The invention discloses a device and method for removing elemental mercury in active coke. The device comprises an ozone generator, a heat exchanger, a blower and an active coke filler and the above parts are connected through pipes. The active coke filler is filled with mercury-containing active coke. Ozone produced by the ozone generator is heated by the heat exchanger, then is fed into the active coke filler through the blower and then undergoes a mercury removal reaction, and after the reaction, the active coke is taken out and is washed by water. The ozone as an oxidant oxidizes the elemental mercury. The device and method are simple, have high efficiency, solve the problem of treatment on elemental mercury in active coke, realize the oxidation of mercury, prevent secondary pollution,realize recovery and recycling of active coke and reduce a cost.
