Embodiment Construction
[0034] Such as figure 2 and image 3 As shown, the catalyst bed layer in the coke area 41 of the regenerator is composed of a cylindrical inner screen 39 and a cylindrical outer screen 40, wherein the diameter of the lower part of the outer screen 40 is larger than that of the upper part, and the upper and lower parts are separated by a Conical connection. The burnt zone 41 of the regenerator is located below the buffer zone 2 and communicated with the catalyst feeding leg 3 .
[0035]The cylindrical upper part of the outer screen 40 and the inner screen 39 constitute the upper fast-burning section 4 of the catalyst bed in the burnt zone, and the cylindrical lower part of the outer screen 40 and the inner screen 39 constitute the upper part of the catalyst bed in the burnt zone. The lower superheating section 6, the conical connection structure part of the outer screen 40 and the inner screen 39 constitute the intermediate transition section 5 of the catalyst bed in the bur...
