Abstract
The invention discloses regenerated catalyst temperature adjustment equipment for a catalytic cracker. The equipment can solve the problems that the catalyst-to-oil ratio of the prior catalytic cracker fails to be flexibly improved according to the actual requirement, or the catalyst-to-oil ratio can be adjusted, but has a complex structure. The regenerated catalyst temperature adjustment equipment provided by the invention is characterized in that: a clapboard is arranged in a regenerator dense phase bed and divides the regenerator dense phase bed into two zones, one zone is a regeneration burning zone, the other zone is a catalyst cooler zone, the lower part of the clapboard is provided with a catalyst inlet of the cooler, a heat removing tube is arranged in the catalyst cooler zone, fluidized rings are sectionally arranged along the vertical height of the catalyst cooler zone,a pre-riser arranged on the lower part of a reaction section of a riser reactor is communicated with the catalyst cooler zone through a conveying pipe of regenerated catalyst and a regeneration slide valve. The invention can ensure that the catalyst-to-oil ratio is flexibly improved during the catalytic cracking reaction.
