Embodiment approach 1
[0034] figure 1 It is a schematic diagram of the basic equipment of Embodiment 1 provided by the present invention.
[0035] figure 1 The equipment includes a dense-phase fluidized bed regeneration zone 1, a delivery pipe 2, a first gas-solid separator 3, a second gas-solid separator 4, a third gas-solid separator 5, diplegs 6, 7 and 9, and a flap valve 8 and 10, flue gas collection chamber 11, main air pipeline 12, standby catalyst delivery pipeline 13, main air distributor 14, regenerated catalyst delivery pipeline 15, flue gas delivery pipeline 16.
[0036] Such as figure 1 As shown, the catalyst to be regenerated enters the regeneration zone 1 through the pipeline 13, and is regenerated by countercurrent contact with the regeneration gas 12 distributed by the main air distributor 14. The regeneration flue gas and the catalyst dust carried by it enter the delivery pipe 2 and enter the first stage The solid separator 3, the catalyst separated by the first-stage gas-solid ...
Embodiment approach 2
[0038] figure 2 It is a schematic diagram of the basic equipment of Embodiment 2 provided by the present invention.
[0039] figure 2 The equipment includes a dense-phase fluidized bed regeneration zone 1, a delivery pipe 2, a first gas-solid separator 3, a second gas-solid separator 4, a third gas-solid separator 5, diplegs 6, 7 and 9, and a flap valve 8 and 10, flue gas collection chamber 11, main air pipeline 12, standby catalyst delivery pipeline 13, fast fluidized bed regeneration zone 14, regenerated catalyst delivery pipeline 15, flue gas delivery pipeline 16, heat extractor 17, regenerated catalyst circulation Line 18.
[0040] Such as figure 2 As shown, the catalyst to be regenerated enters the regeneration zone 14 through the pipeline 13, and is regenerated in contact with the regeneration gas 12. The regenerated flue gas and the catalyst dust carried by it enter the regeneration zone 1, and part of the hot catalyst returns to the regeneration zone 14 through the...
Embodiment approach 3
[0042] image 3 It is a schematic diagram of the basic equipment of Embodiment 3 provided by the present invention.
[0043] image 3 The equipment includes a dense-phase fluidized bed regeneration zone 1, a delivery pipe 2, a first gas-solid separator 3, a second gas-solid separator 4, a third gas-solid separator 5, diplegs 6, 7 and 9, and a flap valve 8 and 10, a flue gas collection chamber 11, a main air pipeline 12, a waiting catalyst delivery pipeline 13, a dense-phase fluidized bed regeneration zone 14, a regenerated catalyst delivery pipeline 15, and a flue gas delivery pipeline 16.
[0044] Such as image 3 As shown, the catalyst to be regenerated enters the regeneration zone 14 through the pipeline 13, and is regenerated in contact with the regeneration gas 12. The regeneration flue gas and the catalyst dust carried by it enter the regeneration zone 1, and part of the hot catalyst returns to the regeneration zone through the circulation pipeline (not shown in the fi...
