Description
Technical field
The utility model relates to a kind of washing device that is used for delayed coker fractionator in refining of petroleum field.
Background technology
Delayed coking is a kind of residual oil to be converted into the crude oil deep processing technology of gas and light, middle matter distillate and coke through degree of depth thermally splitting, also is one of lot of domestic and foreign Petrochemical Enterprises important means of improving yield of light oil; Have that flow process is simple, adaptability to raw material is strong, technology maturation is reliable, characteristics such as investment and process cost are lower.In delay coking process, generate oil gas from the reaction of delayed coking coke drum and enter delayed coker fractionator and carry out fractionation, obtain products such as gasoline, diesel oil.In delayed coker fractionator, coke powder tends to be carried in the product by oil gas and goes, so that has found a large amount of finely-ground coke (6～25 microns of particle diameters) in the product of some delayed coking units, thereby has increased difficulty to following process.For addressing this problem, existing delayed coker fractionator is provided with washing device, comprises that the wax oil that links to each other with the wax oil oil header extracts pipe out, the part wax oil is turned back to top wax oil return tube on the tower tray of wax oil oil header top, the part wax oil is turned back to bottom wax oil return tube on the tower tray of wax oil oil header below.The wax oil that turns back on the tower tray of wax oil oil header above and below flows downward, and contact with mobile oil gas upwards, heat exchange and wash the coke powder that oil gas carries, but washing effect is very limited.The disclosed delayed coker fractionator washing oil of Chinese patent CN202346969U combination distribution device comprises the spraying layer that is positioned at delayed coker fractionator inside, and spraying layer comprises the inlet pipeline assembled unit, and the inlet pipeline assembled unit comprises nozzle.The shortcoming that this washing device exists is: 1. will have which floor tower tray that delayed coker fractionator is positioned at wax oil oil header below now and remove, and change spray washing into, and influence the fractionating effect of oil gas.2. nozzle is located at the below of wax oil oil header; This regional temperature is higher, and the finely-ground coke that washes away is carried secretly up once more by high-temperature oil gas easily, thereby influences washing effect.
Summary of the invention
The purpose of this utility model provides a kind of washing device that is used for delayed coker fractionator, to solve the problem that the existing existing washing effect of washing device is bad, influence the oil gas fractionating effect.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of washing device that is used for delayed coker fractionator, be provided with wax oil and extract pipe out, top wax oil return tube, bottom wax oil return tube, delayed coker fractionator is provided with tower tray, the wax oil oil header, wax oil is extracted pipe out and is linked to each other with the wax oil oil header, the outlet of top wax oil return tube is positioned at the top of wax oil oil header, the outlet of bottom wax oil return tube is between the superiors' tower tray below wax oil oil header and the wax oil oil header, it is characterized in that: the outlet of top wax oil return tube is between the orlop tower tray above wax oil oil header and the wax oil oil header, and the exit of top wax oil return tube is provided with atomizer.
The utility model is mainly used in delayed coker fractionator, the coke powder that washing oil gas carries.Adopt the utility model, have following beneficial effect: (1) atomizer ejection atomizing wax oil, can improve the gas-to-liquid contact situation; Atomizing wax oil washing upwards mobile oil gas carry coke powder the time can obtain washing effect preferably, thereby reduce the coke powder amount of carrying of the product that delayed coker fractionator, especially the finely-ground coke amount of carrying.(2) keep which floor tower tray that delayed coker fractionator is positioned at wax oil oil header below, so just do not influence the fractionating effect of oil gas.The utility model can use on existing delayed coker fractionator easily, does not need to do too many change.(3) atomizer is positioned at the top of wax oil oil header; This regional temperature is lower, and the finely-ground coke that washes away can not carried secretly up once more by low temperature oil gas, can guarantee washing effect.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.The drawings and specific embodiments do not limit the claimed scope of the utility model.
