Delayed coking is a kind of oil secondary processing technology, be mink cell focus taking poor hydrogen as raw material, be warmed up to rapidly pyrogenic reaction temperature through process furnace, enter coke drum and carry out pyrogenic reaction.In the high temperature of 500 DEG C, heavy oil is through thermally splitting and the condensation reaction of the degree of depth, and the gas of producing, gasoline, diesel oil, wax oil, be transported to downstream unit processing by pipeline, and the hundreds of upper kiloton coke of producing remains in coke drum.Coke in coke drum is progressively cooled to below 120 DEG C by steam, water, then pull down the upper and lower head sealing cover of coke drum, coke in coke drum is removed clean with hydraulic decoking equipment, be loaded on the upper and lower head sealing cover of coke drum, enter next step production cycle: oil-feed, reaction, cooling, decoking etc.
Past refinery's delayed coking unit is in process of production when coke removal, all need by weigh blind lid and the feed-pipe of the upper and lower tower mouth of coke drum of several tons of dismounting hand-manipulated, once need nearly two hours, and operator are easily scalded by water, steam, exist great potential safety hazard, the discharge of a large amount of coke cooling waters is also unfavorable for environmental protection.Be applied to tower mouth under coke drum for this kind of full-automatic bottom cover machine of situation.
Automatic bottom cover machine is divided into two stations.
When green coke, equipment connects to form a pressure resistant vessel by skull flange, charging pipe nipple and coke drum and meets coking process and cross range request.When normal work, required sealing force provides by organizing dish spring more.Lock ring is concentrated locking, and protection wound packages is set to hydraulic decoking provides decoking passage, effectively prevents that coke and decoking water from spattering outward, for operator provide good Working environment.
When decoking, first give hydraulic bolt off-load, then drive lock ring oil cylinder, lock ring rotation, the double-screw bolt of hydraulic bolt passes through lower flange.Under jack cylinder effect, lifting device declines, skull flange is opened.Vehicle frame mechanism moves, protection cylinder aligning coke drum center.While starting decoking, upper and lower protection cylinder carries out axially launching motion simultaneously, forms decoking passage; Decoking finishes, and upper and lower protection cylinder is axially regained simultaneously.
Existing full-automatic bottom cover machine is often adopting the single tube band flow-guiding structure on bottom cover machine by high temperature residual oil when charging in device, and the feeding unit of this structure exists the defects such as the inequality of being heated, poor reliability, potential safety hazard are many.
Utility model content
The purpose of this utility model is to provide a kind of novel for the full-automatic two-tube central feeding structure with water conservancy diversion of bottom cover machine, be used for the hot ununiformity of the central feeding structure that reduces existing full-automatic bottom cover machine single tube band water conservancy diversion, improve the reliability of full-automatic bottom cover machine sealing.
For realizing above-mentioned technical purpose, the technical scheme adopting is: a kind of for the full-automatic two-tube central feeding structure with water conservancy diversion of bottom cover machine, comprise the charging pipe nipple that is arranged on tower mouth below under coke drum, for introducing the thrust-augmenting nozzle of high temperature residual oil, with the thrust-augmenting nozzle feed pipe component being connected and the bottom that is arranged on charging pipe nipple below, described charging pipe nipple comprises upper flange, lower flange and be arranged on upper flange and lower flange between annulus, the number of described thrust-augmenting nozzle is even number, and be symmetricly set on charging pipe nipple inside along the circumferential direction of charging pipe nipple, each thrust-augmenting nozzle is all connected with a feed pipe component being located on annulus sidewall, described feed pipe component comprises the multistage feeding pipe connecting successively and is arranged on the joint flange between adjacent two feed-pipes.
Described bottom comprises flange, is arranged on the round end socket of flange inside and is arranged on round end socket for supporting the strut member of thrust-augmenting nozzle.
The number of described thrust-augmenting nozzle is two.
The end of described feed pipe component is all connected to same opening for feed.
The beneficial effects of the utility model are: the two-tube central feeding structure decrease with water conservancy diversion being arranged symmetrically with high temperature residual oil hot ununiformity while entering coke drum, improved the reliability of full-automatic bottom cover machine sealing, improved and installed overall security.
