Abstract
The smart spraying technique of the flow process that steams out greatly in a kind of coking plant of the present invention, including steam-water separator 1, electromagnetic valve A2, electromagnetic valve B 3, accident drainage pipeline 4, nebulizer 5 and coke drum 6, it is characterized in that: water vapour is after steam-water separator 1 processes, the entrance of nebulizer 5 it is transported to by jet chimney 7, accident drainage pipeline 4 it is provided with between steam-water separator 1 and nebulizer 5, transferring of accident drainage pipeline 4 is provided with drainage pipeline 8, accident drainage pipeline 4 is provided with electromagnetic valve B 3, it is provided with manually-operated gate 9 on accident drainage pipeline 4 between electromagnetic valve B 3 and nebulizer 5；Described electromagnetic valve A2, electromagnetic valve B 3 holding wire and computer control system 10 connect.In nebulizer 5, liquid phase water is also atomized into micron-sized drop state by water vapour flow at high speed, and the water of the micron-sized drop state after atomization steams out greatly flow process from the outlet delivery of nebulizer 5 to coke drum 6.
Description
Technical field
The present invention relates to technical field of petrochemical industry, the smart spraying technique of the flow process that steams out greatly in a kind of coking plant.
Background technology
Coking is one of important production procedure of oil-refining chemical.Delayed coking is by the residual oil in oil refining process, after heating through heating furnace, is quickly transferred in coke drum, makes residual oil Pintsch process produce the process of light oil and petroleum coke in coke drum.
Coke drum is as the core process equipment of delayed coking, its operating feature is the circulation that colds and heat succeed each other, and in tower, temperature cycles process is as follows: 1. will be heated to 420 degree through heating furnace: the residual oil of left and right is sent into coke drum and carried out coking reaction and generate petroleum coke and carry out cold burnt process；2. the petroleum coke of generation is cooled to about 45 degree by about 420 degree；3. water under high pressure is passed through coke drum, carries out water-cooled decoking Feng through processes such as preheatings, by 420 degree high temperature residual oil feeding coke drums.
In recent years, many oil plants have been carried out steaming out greatly the trial of full modify-water, and some factory achieves good effect, do not produces the accidents such as burned.But, owing to water is when entering coke drum, has a phase change expansion process, and when bigger one stream of water enters coke drum, the swell increment of water be the biggest.In coke drum porch, water vapor and the excessive expansion volume that produces are easy to cause coke landslide in tower, thus blocking channel, cause the accident.Therefore, design a kind of can make water security enter coke drum energy saving technique it is critical that.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the smart spraying technique of the flow process that steams out greatly in a kind of a kind of coking plant that water security can be made to enter coke drum.
In order to achieve the above object, the smart spraying process of the flow process that steams out greatly in a kind of coking plant of the present invention, including steam-water separator 1, electromagnetic valve A2, electromagnetic valve B3, accident drainage pipeline 4, nebulizer 5 and coke drum 6, it is characterized in that: water vapour is after steam-water separator 1 processes, the entrance of nebulizer 5 it is transported to by jet chimney 7, jet chimney 7 is provided with electromagnetic valve A2, accident drainage pipeline 4 it is provided with between steam-water separator 1 and nebulizer 5, transferring of accident drainage pipeline 4 is provided with drainage pipeline 8, accident drainage pipeline 4 is provided with electromagnetic valve B3, it is provided with manually-operated gate 9 on accident drainage pipeline 4 between electromagnetic valve B3 and nebulizer 5；Described electromagnetic valve A2, electromagnetic valve B3 holding wire and computer control system 10 connect.
In nebulizer 5, liquid phase water is also atomized into micron-sized drop state by water vapour flow at high speed, and the water of the micron-sized drop state after atomization steams out greatly flow process from the outlet delivery of nebulizer 5 to coke drum 6.
The present invention uses the water of micron-sized superfine droplet state, avoid water vapor process and expand the problem caused, so that steaming out greatly flow process basically reach tradition steam out greatly flow process effect while, also make security performance be improved, the service life of coke drum 6 is extended.

Detailed description of the invention
In conjunction with accompanying drawing, the present invention is described further.
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the smart spraying technique of the flow process that steams out greatly in a kind of a kind of coking plant that water security can be made to enter coke drum 6.
In order to achieve the above object, the smart spraying technique of the flow process that steams out greatly in a kind of coking plant of the present invention, including steam-water separator 1, electromagnetic valve A2, electromagnetic valve B3, accident drainage pipeline 4, nebulizer 5 and coke drum 6, it is characterized in that: water vapour is after steam-water separator 1 processes, the entrance of nebulizer 5 it is transported to by jet chimney 7, jet chimney 7 is provided with electromagnetic valve A2, accident drainage pipeline 4 it is provided with between steam-water separator 1 and nebulizer 5, transferring of accident drainage pipeline 4 is provided with drainage pipeline 8, accident drainage pipeline 4 is provided with electromagnetic valve B3, it is provided with manually-operated gate 9 on accident drainage pipeline 4 between electromagnetic valve B3 and nebulizer 5；Described electromagnetic valve A2, electromagnetic valve B3 holding wire and computer control system 10 connect.
In nebulizer 5, liquid phase water is also atomized into micron-sized drop state by water vapour flow at high speed, and the water of the micron-sized drop state after atomization steams out greatly flow process from the outlet delivery of nebulizer 5 to coke drum 6.
When coke drum 6 has an accident, manually 9 water vapour of valve are released in coke drum 6, it is to avoid more serious consequence occurs.
The present invention uses the water of micron-sized superfine droplet state, avoid water vapor process and expand the problem caused, so that steaming out greatly flow process basically reach tradition steam out greatly flow process effect while, also make security performance be improved, the service life of coke drum 6 is extended.
