用于延迟焦化分馏塔的洗涤装置
摘要：
本实用新型公开了一种用于延迟焦化分馏塔的洗涤装置，以解决现有洗涤装置所存在的洗涤效果不好、影响油气分馏效果的问题。本实用新型设有蜡油抽出管(2)、上部蜡油返回管(3)、下部蜡油返回管(4)，所述延迟焦化分馏塔(12)设有塔盘(8)、蜡油集油箱(10)。蜡油抽出管与蜡油集油箱相连，上部蜡油返回管的出口位于蜡油集油箱上方自下而上的第一层塔盘的上方，下部蜡油返回管的出口位于蜡油集油箱下方自上而下的第一层塔盘的上方。上部蜡油返回管的出口和下部蜡油返回管的出口均设有喷头组件，每个喷头组件由圆环管(7)和与圆环管相连的至少2个雾化喷头(1)组成。本实用新型主要用于延迟焦化分馏塔，洗涤油气携带的焦粉。
摘要（英）：

The utility model discloses a washing device for a delayed coking fractionating tower to solve the problems that the existing washing devices are poor in washing effects, thus affecting the oil gas fractionating effects. The washing device is provided with a wax oil extraction pipe (2), upper wax oil return pipes (3) and lower wax oil return pipes (4). The delayed coking fractionating tower (12) is provided with trays (8) and a wax oil collecting tank (10), wherein the wax oil extraction pipe is connected with the wax oil collecting tank; outlets of the upper wax oil return pipes are positioned above the first-layer tray from bottom to top above the wax oil collecting tank; outlets of the lower wax oil return pipes are positioned above the first-layer tray from top to bottom below the wax oil collecting tank; nozzle assemblies are arranged at the outlets of the upper wax oil return pipes and the outlets of the lower wax oil return pipes; and each nozzle assembly comprises a ring pipe (7) and at least two atomizing nozzles (1) connected with the ring pipe. The washing device is mainly used for the delayed coking fractionating tower to wash the coke powder carried by the oil gas.
