Abstract
A built-in decoking device comprises a coke tower body, wherein the tower is internally provided with a longitudinal screw rod, the longitudinal screw rod is fixedly connected with a spiral scratching blade on the inner wall of the tower body and is also provided with a propeller blade; the bottom of the tower body is connected with an extruder shell; and the extruder shell is internally provided with a spiral extruder, and a coke sealing chamber is arranged in front of the extruder shell. When in use, the material acts on the propeller blade to drive the longitudinal screw rod, the longitudinal screw rod drives the spiral scratching blade to lead the mixture of the coke and condensed oil on the inner wall of the tower body to be extruded into the extruder shell, the spiral extruder pushes the condensed oil into the coke sealing chamber, and the coke is shaped by the necking method to be filled in the coke sealing chamber in the solid state, so the condensed oil is forced to be pushed to the back of the spiral extruder; in the utility model, since the coke tower is internally provided with the spiral scratching blade, the coke tower can directly decoke during the production process, and the production equipment can be better utilized.
Description
Technical field
The utility model relates to a kind of coke removing appts., particularly a kind of built-in coke removing appts..
Background technology
The coke drum of refining of petroleum delayed coking at present can not move automatically continuously, adopt batch mode of operation, coke drum green coke and decoking carry out respectively, switching cycle was generally 48 hours, wherein the green coke time only is about 24 hours, other times in cycle all are used for complicated decoking program, at present main decoking program is for after coke drum stops charging, blows water vapor in the tower earlier and catches up with most residue oil gas and cooling, then the capable again decoking of water-cooled, decoking extensively adopts hydraulic decoking, the general 12mpa pressure high pressure water that adopts, this decoking mode operation is loaded down with trivial details, can not make the coke drum continuous production, and need hydraulic equipment, greatly waste the resource and the energy.
Summary of the invention
The purpose of this utility model is to remedy the shortcoming of above-mentioned prior art, has proposed a kind of built-in coke removing appts., has simple in structurely, cuts down the consumption of energy, and can realize coke drum quantity-produced characteristics.
The technical solution of the utility model is achieved in that a kind of built-in coke removing appts., comprise the coke drum tower body, device has longitudinal screw in the tower body, longitudinal screw is connected with the decoking device motor that the tower body top is provided with, longitudinal screw scrapes sheet with spiral on the tower body inwall and is connected mutually, propeller blade also is installed on the longitudinal screw, correspondence position at propeller blade offers opening for feed, the tower body bottom is connected with the extruder housing, in the extruder housing spiral is installed and pushes device, spiral is pushed device and is connected with the extruder motor at rear, extruder housing the place ahead is provided with the coke sealing chamber, be provided with valve in the coke sealing chamber, valve the place ahead offers the coke outlet, and extruder housing rear offers the condensed oil outlet.
Described opening for feed is positioned at the correspondence position of propeller blade, and the opening for feed opening has the angle of inclination of level.
The diameter of described coke sealing chamber is pushed device place diameter of the housing less than spiral, and the length of coke sealing chamber is not less than 10cm.
Since the utility model in coke drum, installed spiral scrape sheet make coke drum can be in process of production direct decoking, front end in extruder is provided with the coke sealing chamber simultaneously, better make condensed oil be split into the extruder rear, realized the quality of carrying out and guaranteed production continuously of producing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are elaborated.
With reference to Fig. 1, the utility model comprises coke drum tower body 1, device has longitudinal screw 2 in the tower body 1, longitudinal screw 2 is connected with the decoking device motor 3 that the tower body top is provided with, longitudinal screw 2 scrapes sheet 4 with spiral on the tower body inwall and is connected mutually, propeller blade 5 also is installed on the longitudinal screw 2, correspondence position at propeller blade 5 offers opening for feed 6, tower body 1 bottom is connected with extruder housing 7, spiral is installed in the extruder housing 7 pushes device 8, spiral is pushed device 8 and is connected with the extruder motor 9 at rear, extruder housing 7 the place aheads are provided with coke sealing chamber 10, be provided with valve 11 in the coke sealing chamber 10, valve 11 the place aheads offer coke outlet 12, and extruder housing 7 rears offer condensed oil outlet 13.
Described opening for feed 6 is positioned at the correspondence position of propeller blade 5, and opening for feed 6 is provided with the opening angle of inclination of level.
The diameter of described coke sealing chamber 10 is pushed the diameter of device 8 place's extruder housings 7 less than spiral, and the length of coke sealing chamber 10 is not less than 10cm.
During work, raw material enters in the tower body 1 by opening for feed 6, raw material acts on the propeller blade 5, propeller blade 5 drives longitudinal screw 2, longitudinal screw 2 drive spirals scrape sheet 4 and carry out decoking, also can utilize decoking device motor 3 to supply power simultaneously, being scraped sheet 4 by spiral in process of production attached to the mixture of coke on the tower body inwall and condensed oil scrapes the tower body bottom and enters in the extruder housing 7, extruder motor 9 drive spirals are pushed device 8 mixture are pushed to coke sealing chamber 10 at this moment, thereby coke is full of whole coke sealing chamber 10 by the necking down moulding with the solids form and makes condensed oil be forced to be sent to the rear that spiral is pushed device 8 in coke sealing chamber 10, be provided with valve 11 in the coke sealing chamber 10, regulate the speed of the discharging of the coke by valve 11, coke is discharged from coke outlet 12 through valve 11, and condensed oil then is drawn out of by the condensed oil outlet 13 that extruder housing 7 rears are offered.
Because opening for feed 6 offers the angle of inclination of level, so raw material acts on the outside of propeller blade 5, more can effectively utilize the reactive force of raw material to propeller blade 5; The diameter of coke sealing chamber 10 is pushed device place diameter of the housing less than spiral simultaneously, and the length of coke sealing chamber is not less than 10cm, make that coke can compressed moulding in coke sealing chamber 10, and coke is very closely knit is full of coke sealing chamber 10, and gas-liquid is gone out coke outlet 12 when having prevented at material few or idle running.
Since the utility model in coke drum, installed spiral scrape sheet make coke drum can be in process of production direct decoking, more can make full use of production unit; Make full use of raw material and wash away the power that is brought and saved the energy by propeller blade on the transverse screw is set; Front end in extruder is provided with the coke sealing chamber, better makes condensed oil be split into the extruder rear, has guaranteed the quality of producing.
