AI Technical Summary
Existing activated carbon injection devices lack a crushing structure, resulting in uneven activated carbon particle size, which may scratch the pipe wall and block the injection port. The single injection method results in a limited contact area between activated carbon and flue gas, reducing treatment quality and utilization rate, and making it difficult to adapt to different operating conditions and changes in flue gas composition.
An activated carbon injection device incorporating a crushing and rotating structure was designed. The activated carbon is crushed and uniformly injected through a conical extrusion column and a rotating motor, ensuring that the activated carbon particles are of uniform size and in full contact with the flue gas.
It improves the efficiency of activated carbon injection and the quality of flue gas treatment, avoids pipe wall scratches and blockages, increases the contact area between activated carbon and flue gas, and improves the flexibility and adaptability of the treatment effect.
