Embodiment 1

[0037] Such as figure 1 As shown, the invention discloses a defoaming injection device. Wherein, the defoaming injection device includes a defoaming agent supply assembly 1 and a spraying part 2 .

[0038] The sprinkler 2 is installed in the coke tower 3, and the sprayer 2 can be any structure that can completely cover the top surface of the coke in the coke tower 3 with the defoamer, for example, it can be an atomizing nozzle or a plurality of through holes evenly distributed board.

[0039] The defoamer supply assembly 1 provides defoamer to the sprinkler 2 , and the defoamer sprayed from the sprayer 2 can completely cover the top surface of the coke in the coke drum 3 .

[0040] In the defoaming injection device disclosed in the present invention, when the coke height in the coke tower 3 reaches the normal height position, the defoamer supply assembly 1 starts to provide the spraying part 2 with defoaming agent, so that the sprayed part 2 sprays The defoamer can complete...

Embodiment 2

[0042] In the second embodiment provided by the present invention, the structure of the defoaming injection device in this embodiment is similar to the structure of the defoaming injection device in the first embodiment, and the similarities will not be repeated, and only the differences will be introduced.

[0043] In this embodiment, the present invention specifically discloses that the spraying member 2 is an atomizing nozzle, and the atomizing nozzle can atomize and spray the defoamer into the coke drum 3 . Using the atomizing nozzle, the defoamer can be atomized into extremely fine mist droplets, and the mist liquid sprayed out through the atomizing nozzle can fully contact with the oil and gas, eliminating the phenomenon of dripping and dripping, which can greatly improve the gas-liquid contact efficiency.

[0044] Further, the present invention discloses that the atomizing nozzle is installed on the inner top of the coke tower 3, so as to facilitate downward spraying of ...

Embodiment 3

[0058] In the third embodiment provided by the present invention, the structure of the defoaming injection device in this embodiment is similar to the structure of the defoaming injection device in the second embodiment, so the similarities will not be repeated, and only the differences will be introduced.

[0059] In this embodiment, the present invention discloses that the spraying member 2 is a spraying plate, and the spraying plate is clamped on the coke tower 3. The spraying plate can be arranged perpendicular to the axis of the coke tower 3, or can be installed at a certain angle. In addition, there are a plurality of spray through holes evenly distributed on the spray plate, and the defoamer falls onto the spray plate through the entrance of the coke tower 3, and is evenly sprayed into the coke tower 3 through the spray plate.

[0060] Lead one path of hot oil from the outlet of the hot oil pump 102, pass through the booster pump 103, mix with the defoamer, and pour into...

Abstract

The invention discloses a defoaming injection device and a delayed coking drum device. The defoaming injection device comprises a defoaming supply component and a spraying part, wherein the spraying part is mounted in a coke drum; the defoaming supply component is used for supplying a defoaming agent for the spraying part; and the defoaming agent sprayed from the spraying part is capable of completely covering the top surface of coke in the coke drum. By adopting the defoaming injection device disclosed by the invention, when crude coke in the coke drum meets a normal height position, the defoaming supply component is powered on to provide the defoaming agent to the spraying part, and the defoaming agent sprayed from the spraying part is capable of completely covering the top surface of the coke in the coke drum, sufficiently contacts with a foam layer in the coke drum and is dropped down as droplets, so that the foam layer can be well pressed, the height of the crude coke in the cokedrum can be increased, and the utilization efficiency of the coke drum can be improved.

Description

technical field [0001] The invention relates to the technical field of delayed coke equipment, in particular to a defoaming injection device and a delayed coke tower device. Background technique [0002] In the delayed coke unit, a large amount of oil and gas produced by the high temperature cracking of the raw material oil is very easy to foam in the coke tower. As the coke layer rises, the foam will rush out of the top of the tower, causing coking and blocking of the oil and gas pipeline, and increasing the amount of coke powder carried in the oil and gas, which will affect the normal operation of the fractionation tower and the processing capacity of the coke tower; the upper part of the coke tower A large amount of foam is formed, which also seriously affects the processing capacity and product quality of the coke plant. [0003] Therefore, how to reduce the height of the coke tower foam layer and suppress the generation of foam is a technical problem to be solved urgen...
