催化裂化装置的主要设备再生器,是一种使表面含有焦炭的待生催化剂经过高温烧焦后得以再生的设备,如何提高再生器的烧焦强度已成为设计中的一个主要课题。为了使催化剂与空气分配均匀,促进气固两相接触和支撑催化剂,再生器底部有一重要内构件——空气分布器。空气分布器,在60年代初设计的催化裂化装置中是一个向上凹的球面板,凹曲率为83mm/m称为分布板。板上开有射向球面
The main equipment regenerator of a catalytic cracking unit is a device that regenerates the spent catalyst containing coke on the surface after being burnt at a high temperature. How to improve the scorch strength of the regenerator has become a major issue in the design. In order to make the catalyst and the air evenly distributed, to promote the gas-solid contact and support the catalyst, the regenerator has an important internal components at the bottom - air distributor. Air distributor, designed in the early 60’s catalytic cracking unit is an upward concave spherical plate, concave curvature of 83mm / m is called the distribution board. The board has a spherical surface
