Abstract
The utility model discloses a novel spray nozzle for a decoking device as well as a rectifier structure. A rectifier and the spray nozzle are installed in a processing hole in a decoking device body; a clearance is formed between an outer wall and a body installation hole; an excircle of the spray nozzle is provided with a seal ring, and the spray nozzle and the decoking body are sealed; the spray nozzle and the rectifier are connected by threads; the other end of the spray nozzle and a pressing cover are connected by threads; a bolt hole of the pressing cover is provided with two threaded holes for jacking up; when the spray nozzle and the rectifier are detached, the spray nozzle and the rectifier can be taken out by jacking up the pressing cover; the rectifier is convenient to overhaul; the using effect of the rectifier is ensured; and the maintaining cost is lowered.
Description
Technical field
The utility model relates to refining of petroleum industry delayed coking unit hydraulic decoking equipment, specifically a kind of novel decoking device nozzle and rectifier structure.
Background technology
Delayed coking is a kind of Petroleum Processing Technology, is to be raw material with the mink cell focus, is warmed up to the pyrogenic reaction temperature rapidly through process furnace, enters coke drum and carries out pyrogenic reaction.Heavy oil carries out thermally splitting and the condensation reaction of the degree of depth, and the gas of producing, gasoline, diesel oil, wax oil are handled to downstream unit by pipeline, and the hundreds of ton coke of producing is stayed in the coke drum.Coke in the coke drum progressively is cooled to below 120 ℃ with steam, water, open the upper and lower end socket lid of coke drum then, coke in the coke drum is removed clean with hydraulic decoking equipment, close the upper and lower end socket lid of coke drum again, enter next step production cycle again: oil-feed, reaction, cooling, decoking etc.
Hydraulic decoking equipment generally includes: equipment such as drive on decoking water pump, valve, sebific duct, drilling rod top, drilling rod, decoking device, windlass, tackleblock.The decoking water pump produces the decoking water of certain energy, by valve, sebific duct, drilling rod top drive, drilling rod enters decoking device, at last from the nozzle ejection of decoking device.Decoking device has boring, cuts burnt two groups of nozzles, when hydraulic decoking begins usually, use decoking device boring nozzle to spray decoking water downwards earlier, the coke drum center is got out the through hole of about 1 meter of a diameter, and then use decoking device to cut burnt nozzle to enlarge passage gradually to both sides ejection decoking water, at the broken outflow coke drum of this process coke to Chu Jiaochi, the coke of this work in eliminating coke drum, decoking work just finishes.
In decoking device, for the high pressure water that makes nozzle ejection has enough operating distance, all rectifier will be set in nozzle, and rectifier to there be enough length guaranteeing the smoothness of water, thereby the water of nozzle ejection is not dispersed, have higher concentration class.Present decoking device rectifier mounting means is two kinds: a. one end directly is welded on the rectification pipeline, and the other end connects nozzle; B. be installed in the injector head, pack into end and the welding of decoking device body, the other end is installed nozzle.Because rectifier all adopts welding process with being connected of decoking device body, rectifier can't be dismantled during maintenance repair, can not in time find the damaged condition of rectifier, influences the jet quality; When rectifier was keeped in repair, difficulty was big, cost is higher.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of novel decoking device with nozzle and rectifier structure, and this is simple in structure, and dismounting easily overhaul very conveniently, so has improved overhaul efficiency, reduces production costs.
The technical scheme that the utility model adopts is: a kind of novel decoking device nozzle and rectifier structure, comprise the decoking device body, gland, nozzle and rectifier, be provided be used to the open holes that nozzle and rectifier are set at the decoking device body, described nozzle one end is connected by engage thread with rectifier, the other end is connected by engage thread with gland, and gland, nozzle and rectifier constitute integrative-structure and whole being arranged in the open holes of decoking device body, gland is arranged on the decoking device body by web member, described nozzle and rectifier all and between the open holes inner hole wall of decoking device body have the gap, are provided with sealing-ring between the open holes inner hole wall of nozzle and decoking device body.
Described gland is connected on the decoking device body by screw.
The beneficial effects of the utility model are: all adopt between rectifier, nozzle and the gland to be threaded, during installation earlier with it by being threaded to one, the integral body body open holes of packing into again.Lay down the trip bolt of gland during dismounting earlier, by two jack-up threaded holes on the gland nozzle and rectifier are split out body again.The utility model can make rectifier in use fast dismantle, overhaul and change, and guarantees its result of use, reduces maintenance cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark among the figure: 1, decoking device body, 2, gland, 3, sealing-ring, 4, nozzle, 5, screw, 6, rectifier.
Embodiment
Specify set-up mode of the present utility model and effect in conjunction with the accompanying drawings and embodiments.
As shown in the figure, a kind of novel decoking device nozzle and rectifier structure, comprise decoking device body 1, gland 2, nozzle 4 and rectifier 6, be provided be used to the open holes that nozzle 4 and rectifier 6 are set at decoking device body 1, described nozzle 4 one ends and rectifier 6 are connected by engage thread, the other end and gland 2 are connected by engage thread, and gland 2, nozzle 4 and rectifier 6 constitute integrative-structure and whole being arranged in the open holes of decoking device body 1, gland 2 is arranged on the decoking device body 1 by web member, for example be connected on the decoking device body 1 by screw 5, described nozzle 4 and rectifier 6 all and between the open holes inner hole wall of decoking device body 1 have the gap, are provided with sealing-ring 3 between the open holes inner hole wall of nozzle 4 and decoking device body 1.
When the utility model is installed, at first rectifier 6 right-hand members extend into the open holes inside of decoking device body 1, left end adopts with nozzle 4 and is threaded, nozzle 4 cylindricals and decoking device body 1 have the gap, adopt sealing-ring 3 to seal, nozzle 4 left ends adopt with gland 2 and are threaded, and gland 2 adopts screw 5 to carry out fastening with decoking device body 1.
Adopt the utility model structure when the maintenance repair of decoking device, can pass through removable screw 5, utilize two jack-up threaded holes on the gland 2 that gland 2, nozzle 4, sealing-ring 3 and rectifier 6 are all split out in decoking device body 1, in time nozzle 4 and rectifier 6 are overhauled.
