Abstract
A kind of online coke cleaning apparatus of coking heater of the utility model, it includes heating furnace, coke drum, fractionating column, radiation pump, waterflood-transmission line, boiler tube, enters radiation pipeline and go out radiation port pipeline, be characterized in heating furnace, coke drum, fractionating column, radiation pump side-by-side series form interior closed loop closed conduct, heating furnace both sides have three road waterflood-transmission lines to be attached with boiler tube, and the pipeline that the boiler tube of both sides is drawn is connected with coke drum bottom.The oil product in boiler tube is purged by deaerated water, it is different from boiler tube thermal coefficient of expansion using coke, by 4 priority drastic changes of heating-furnace bore temperature, make focus layer in boiler tube implosion and fragment into small coke button, carried by steam in boiler tube to coke drum, reach online coke cleaning purpose.Compared with prior art, with it is easy make, install be simple and convenient to operate, practical, cost-effective, reduction energy consumption, safety coefficient it is high, the advantage of online coke cleaning on the basis of device is not stopped work, can be realized.
Description
First, technical field
The utility model is related to petroleum chemical industry, and specifically one kind Hand scarf on the basis of device is not stopped work adds
Hot stove boiler tube coke device.
2nd, background technology
At present, delayed coking feedstock property worse and worse, causes Furnace Tube of Coker Unit coking speed to be accelerated, heating furnace fortune
Line period shortens.The tower coking of a stove two is general to be burnt using shut-down or mechanical decoking processing after tube coking at home,
Professional coke cleaning troop is asked to carry out coke cleaning every time, coke cleaning expense is at 70,000 yuan or so.The shut-down coke cleaning of other device reduces device and added
Work amount, and device goes into operation, the shut-down energy, supplies consumption are big, device shutting down once needs to spend 300,000 or so, and production cost is big
It is big to improve, economic benefit reduction.Security incident easily occurs for the safety coefficient reduction of device during shutting down simultaneously.
So although a set of online coke cleaning has certain technical difficulty and risk at exploitation, but it is necessary using effective
Technical scheme and measure carry out online coke cleaning.
3rd, the content of the invention
The utility model for problem above there is provided one kind it is easy for installation, simple to operate, stable, can be in device
A kind of online coke cleaning apparatus of coking heater of online coke cleaning is realized on the basis of not stopping work.
The purpose of this utility model is achieved through the following technical solutions：
A kind of online coke cleaning apparatus of coking heater, it includes heating furnace, coke drum, fractionating column, radiation pump, water injection pipe
Line, boiler tube, enter radiation pipeline and go out radiation port pipeline, be characterized in heating furnace, coke drum, fractionating column, radiation pump side-by-side series shape
Into interior closed loop closed conduct, the waterflood-transmission lines of heating furnace both sides draws three road waterflood-transmission lines respectively, first of waterflood-transmission line with
Heating furnace middle and upper part is connected, and twice pipeline is connected with heating the boiler tube of furnace bottom in addition, the pipe of the boiler tube extraction of heating furnace both sides
Road, coke drum bottom is connected to by radiating outlet conduit, and two pipeline connections are drawn in the radiation pipeline that goes out of radiation pump connection
On waterflood-transmission line at the top of to heating furnace.
A kind of online coke cleaning apparatus of coking heater of the utility model compared with prior art, with easy making, is installed
Be simple and convenient to operate, it is practical, can be on the basis of device not be stopped work, the characteristics of realizing online coke cleaning additionally has
Following remarkable advantage：
1st, stopped work by online coke cleaning avoiding device, reduce open because of device, the cost consumption brought of stopping work, saved life
Cost is produced, about 700,000 yuan can be saved for company every year.
2nd, heating furnace tube tube wall temperature highest declines 94 DEG C in the utility model, and minimum 25 DEG C of decline averagely reduces by 46
DEG C, furnace fuel gas consumption is reduced, energy consumption is reduced, burner hearth is solved, the problem of tube wall temperature is high, eliminates burner hearth, stove
The high potential safety hazard come to device band of pipe temperature.
4th, illustrate
Fig. 1 is structural representation of the present utility model
In figure：1 heating furnace, 2 coke drums, 3 fractionating columns, 4 radiation pumps, 5 waterflood-transmission lines, 6 enter radiation pipeline, 7 go out radiant tube
Road, 8 boiler tubes
5th, embodiment
A kind of online coke cleaning apparatus of coking heater of the utility model is made further with reference to Figure of description
Bright, the utility model is in the newly-built implementation of Shandong Sheng Xing Chemical Co., Ltd.s.
As shown in figure 1, a kind of online coke cleaning apparatus of coking heater of the utility model includes heating furnace 1, coke drum 2, divided
Evaporate tower 3, radiation pump 4, waterflood-transmission line 5, boiler tube 8, enter radiation pipeline 6 and go out radiation port pipeline 7, wherein heating furnace 1, coke drum 2,
Fractionating column 3, the radiation side-by-side series of pump 4 form interior closed loop closed conduct, and the waterflood-transmission line 5 of the both sides of heating furnace 1 draws three respectively
Road waterflood-transmission line, first of waterflood-transmission line is connected with the middle and upper part of heating furnace 1, in addition twice pipeline and the stove in the burner hearth of heating furnace 1
Pipe 8 is connected, the pipeline of the extraction of boiler tube 8 of the both sides of heating furnace 1, the bottom of coke drum 2 is connected to by entering radiation pipeline 6, in radiation
The radiation pipeline 7 that goes out of the connection of pump 4 is drawn on the waterflood-transmission line 5 that two pipelines are connected at the top of heating furnace 1.
In plant running, coke cleaning link is being carried out, radiation pump 4 of stopping transport injects deaerated water into waterflood-transmission line 5, utilized
The steam that deaerated water enters the generation of boiler tube 8 is purged to the oil product in boiler tube 8, and the tube wall of boiler tube 8 is rapidly heated to 650 after purging
DEG C, then the quickly flame-out cooling of heating furnace 1, improves water injection rate, the tube wall temperature of boiler tube 8 is reduced rapidly to 200 DEG C, utilizes coke
It is different from the thermal coefficient of expansion of boiler tube 8, by 4 priority drastic changes of the fire box temperature of heating furnace 1, make focus layer in the implosion of boiler tube 8
With fragment into small coke button, carried by steam in boiler tube 8 by going out radiation pipeline 7 to coke drum 2, so that coke button in boiler tube 8
Progressively come off and reach coke cleaning purpose.After the completion of coke cleaning, the oil phase opened in radiation pump 4, fractionating column 3 is entered by going out radiation pipeline 6
Enter heating furnace, online coke cleaning is completed.
