(1) The application range of activated carbon is becoming more and more extensive, but because activated carbon is easily saturated during use and loses its adsorption capacity, it must be replaced frequently to achieve the effect of use. Activated carbon is expensive, and each time the new carbon is replaced, the operating cost of the enterprise is increased. However, the regeneration and activation of the saturated waste activated carbon can restore the adsorption performance to more than 95%, and the carbon loss rate after regeneration is less than 20%. The purpose of circular economy can be achieved.

(2) The waste activated carbon activation device developed by our company can separate the high-boiling point substances (oil and gas) produced by the activation process through a four-phase separator for recovery, and use the recovered materials (oil, gas) for heating of the activation device, and the remaining part Thermal energy can be recycled or connected to the grid for power generation, realizing resource and energy reuse, reducing operating costs, and having good application prospects.

(1) The system is equipped with a heat energy recovery system, which mainly includes the heat energy recovery of drying tail gas and the heat energy recovery of gasification tail gas;

(2) The system is equipped with an exhaust gas energy recovery system. The light oil with low boiling point in the drying process is recovered after being evaporated, and it is converted into the energy required for the drying and gasification process;

(3) Adopt indirect combustion heating method to reduce heat loss and reduce total carbon emission reduction;

(4) The system is equipped with a combustible gas generator to provide energy for drying and gasification, and excess electricity can be connected to the grid.
