一种催化裂化装置
摘要：
本发明公开了一种催化裂化装置。该催化裂化装置包括冷却器(4)、取热器(20)、原料油喷嘴(10)、反应器(12)、沉降器(27)、烧焦器(15)和管式烧焦器(11)，冷却器(4)底部对称设置两个淹流管，反应器(12)为设置有两个催化剂入口的管式反应器，淹流管通过再生催化剂输送管与催化剂入口连通，反应器(12)出口与沉降器(27)相连通，沉降器(27)下部为沉降器汽提段(30)，沉降器汽提段(30)依次与烧焦器(15)和管式烧焦器(11)相连通，管式烧焦器(11)再与冷却器(4)相连通。使用本发明可降低生成汽油的烯烃含量10～20个体积百分点，汽油辛烷值(RON)提高0.1～0.5个单位，柴油品质得到提高；本发明装置结构简单，能耗低，易操作，单套装置经济效益可得到大幅提高。
摘要（英）：

The invention discloses a catalytic cracking device which comprises a cooler (4), a heat remover (20), a raw material oil nozzle (10), a reactor (12), a precipitator (27), a burner (15) and a tubular burner (11). Two submerged flow pipes are symmetrically arranged on the bottom of the cooler (4). The reactor (12) is a tubular reactor on which two catalyst inlets are arranged. The submerged flow pipes are communicated with the catalyst inlets through a regenerated catalyst transportation tube. The outlet of the reactor (12) is communicated with the precipitator (27). The lower part of the precipitator (27) is a precipitator stripping portion (30), which is successively communicated with the burner (15) and the tubular burner (11). The tubular burner (11) is communicated with the cooler (4). By means of the device, the content of olefin in gasoline can be reduced by 10-20% by volume and the octane number (RON) of the gasoline can be increased by 0.1-0.5 units. The device can improve diesel quality, is simple in structure, is low in energy consumption, is easy to operate and is greatly increased in single-set economic benefit.
