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.

Example Embodiment

[0023] Example 1

[0024] The mercury removal method of mercury-containing activated coke specifically includes the following steps:

[0025] Fill the mercury-containing activated coke into the activated coke filler, adjust the gas output of the ozone generator to 1g/h, and enter the heat exchanger through the pipe. The ozone gas is heated to 100°C, blown by the blower, and then input from the pipe. In the active coke filler, there is 1m in the active coke filler 3 The mercury content is 10μg/m 3 After 30 minutes, the activated coke was taken out and washed with water. The mercury removal rate of the activated coke reached 99.3%.
