Embodiment 2

[0039] In addition to the technical solution of Example 1, the technical solution of this embodiment also includes the following technical solution: the gas output port of the fluidized bed activation reactor 2 and the gas output port of the raw coal carbonization furnace 1 are connected with the Sleep activation furnace 3 respectively. The combustion chambers are connected by valves. Through the above technical scheme, when the heat of the Sleep activation furnace is insufficient and the temperature increase is limited, the heat can be supplemented by activating the gas in the fluidized bed activation reactor or carbonizing the coal gas in the raw coal carbonization furnace to realize the rapid adjustment / switching of the Sleep, ensuring Continuous and high-quality production of activated carbon in the Sleep activation furnace.

Embodiment 3

[0041] A raw coal carbonization activation co-production process, said process is implemented using the system described in Example 1; said process comprises the steps of:

[0042] The raw coal is sent into the raw coal carbonization furnace 1 after being pulverized and briquetted by the pulverizer 6 and the briquetting machine 7, and the carbonized material with a particle size of 0.5-6 mm produced by carbonization is sent into the fluidized bed activation reactor 2 Activate to form the first activated carbon, and send the carbonized material with a particle size of 3-12 mm into the Sleep activation furnace 3 for activation to form the second activated carbon;

[0043] The raw coal is sent into the raw coal carbonization furnace 1 after being pulverized and briquetted to be carbonized and the raw coal gas is produced by-product at a temperature of about 280°C; the raw coal gas produced in the three raw coal carbonization furnaces 1 is sent to the first incineration chamber In...
