Description
Technical field
The utility model relates to technical field of petrochemical industry, the smart spraying technique of the flow process that specifically steams out greatly in a kind of coker.
Background technology
Coking is one of important Production Flow Chart of oil-refining chemical.Delayed coking is by the residual oil in oil refining process, after process furnace heating, transfers to rapidly in coke drum, makes residual oil Pintsch process produce the process of lightweight oil and petroleum coke in coke drum.
Coke drum is as the core process equipment of delayed coking, its operating features is the circulation that colds and heat succeed each other, and in tower, temperature cycle process is as follows: be 1. heated to 420 degree by through process furnace: the residual oil of left and right is sent into coke drum and carried out coking reaction and generate petroleum coke carrying out cold burnt process; 2. the petroleum coke of generation is cooled to about 45 degree by about 420 degree; 3. high pressure water is passed into coke drum, carry out water-cooled decoking Feng through processes such as preheatings, 420 degree of high temperature residual oil are sent into coke drum.
In recent years, many refinerys have carried out steaming out greatly the trial of full modify-water, and some factory achieves good effect, does not produce the accidents such as burned.But, because water is when entering coke drum, have a phase change expansion process, and when one current comparatively large enter coke drum, the swell increment of water is very large.In coke drum ingress, water vapor and the excessive expanding volume that produces is easy to cause coke landslide in tower, thus blocking channel, cause the accident.Therefore, it is vital for designing a kind of energy-saving technique that water security can be made to enter coke drum.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of smart spraying technique that water security can be made to enter in a kind of coker of coke drum the flow process that steams out greatly.
In order to achieve the above object, the smart spraying technique of the flow process that steams out greatly in a kind of coker of the utility model, comprise steam separator 1, magnetic valve A2, magnetic valve B 3, accident drainage pipeline 4, spraying gun 5 and coke drum 6, it is characterized in that: water vapor is after steam separator 1 processes, the entrance of spraying gun 5 is transported to by steam-pipe 7, steam-pipe 7 is provided with magnetic valve A2, accident drainage pipeline 4 is provided with between steam separator 1 and spraying gun 5, transferring of accident drainage pipeline 4 is provided with drainage pipeline 8, accident drainage pipeline 4 is provided with magnetic valve B 3, accident drainage pipeline 4 between magnetic valve B 3 and spraying gun 5 is provided with manually-operated gate 9, described magnetic valve A2, magnetic valve B 3 signal wire are connected with computer control system 10.
In spraying gun 5, liquid phase water is also atomized into micron-sized drop state by water vapor flow at high speed, and the water of the micron-sized drop state after atomization to steam out greatly flow process from the outlet delivery of spraying gun 5 to coke drum 6.
The utility model adopts the water of micron-sized superfine small droplets state, avoid water vapor process to expand the problem caused, thus make to steam out greatly flow process substantially reach tradition steam out greatly flow process effect while, also make that safety performance is improved, the work-ing life of coke drum 6 extended.
Accompanying drawing explanation
Fig. 1 is connection diagram of the present utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of smart spraying technique that water security can be made to enter in a kind of coker of coke drum 6 flow process that steams out greatly.
In order to achieve the above object, the smart spraying technique of the flow process that steams out greatly in a kind of coker of the utility model, comprise steam separator 1, magnetic valve A2, magnetic valve B 3, accident drainage pipeline 4, spraying gun 5 and coke drum 6, it is characterized in that: water vapor is after steam separator 1 processes, the entrance of spraying gun 5 is transported to by steam-pipe 7, steam-pipe 7 is provided with magnetic valve A2, accident drainage pipeline 4 is provided with between steam separator 1 and spraying gun 5, transferring of accident drainage pipeline 4 is provided with drainage pipeline 8, accident drainage pipeline 4 is provided with magnetic valve B 3, accident drainage pipeline 4 between magnetic valve B 3 and spraying gun 5 is provided with manually-operated gate 9, described magnetic valve A2, magnetic valve B 3 signal wire are connected with computer control system 10.
In spraying gun 5, liquid phase water is also atomized into micron-sized drop state by water vapor flow at high speed, and the water of the micron-sized drop state after atomization to steam out greatly flow process from the outlet delivery of spraying gun 5 to coke drum 6.
When coke drum 6 has an accident, manually valve 9 is released water vapor in coke drum 6, avoids more serious consequence occurs.
The utility model adopts the water of micron-sized superfine small droplets state, avoid water vapor process to expand the problem caused, thus make to steam out greatly flow process substantially reach tradition steam out greatly flow process effect while, also make that safety performance is improved, the work-ing life of coke drum 6 extended.
