Description
Technical field
The present invention relates to a kind of coke feedway combining with conveyer for vertical charging, particularly petroleum coke delivery system.
Background technology
Delayed coking be a kind of by heavy oil through degree of depth thermal cracking be converted into gas, light in the heavy oil deep processing technique of matter distillate and coke, the feature such as have that de-charcoal is thorough, flow process is simple, technology maturation, plant investment are lower, it has become one of important process in Heavy Oil Processing Technology.
Along with crude oil heaviness, in poor quality ratio increase, and the progress of crude oil depth processing, delayed coking is more and more important in the status of processing heavy, crude oil with poor quality, the output of petroleum coke constantly increases, the crude oil of China's consumption is at present about 3.5 hundred million tons, at present domestic delayed coking unit approximately more than 60 covers take short residuum or short residuum blended asphalt and catalytic slurry as raw material, the about 78Mt/a of working ability; Delayed coking unit take heavy crude, bunker c or coal tar naphtha as raw material also has nearly 50 covers, the about 35Mt/a of its total working ability; The end of the year 2010, the total working ability of domestic delayed coking exceedes 110Mt/a, pressing crude oil coke 3～5% calculates, China is every year by the petroleum coke of more than 1,000 ten thousand tons of outputs, decoking is a link important in delayed coking with transporting coke, in prior art, waterpower method decoking is generally to use in delayed coking unit, utilizes the petroleum coke in high pressure water STRENGTH ON COKE tower to cut, and connects subsequently burnt band water and flows into Chu Jiaochi through inclined chute.Have both the burnt outdoor uncovered setting in pond of storage of memory function, in pond, decoking water recycles after flowing automatically to filtering ponds, and in pond, coke is utilize grab crane a pipeful of ground batch turning or catch on outward transport train, automobile or catch on the grid of belt conveyor systems.In batch turning with catch in transport process, spreading is unavoidable, and coke and coke powder pollute ambient environment, ground falls to having the smell of coke volatile matter in coke powder, air, contaminated environment, causes damage to operator's health, also there will be the unexpected safety misadventures such as fire.
In scheme described in the patent of invention " extraction, discharge and the transfer system of petroleum coke " of 2010.05.05 Granted publication be: first the coke and the water that leave coke drum enter prebreaker, the coke of bulk is broken, then enter buffering hopper, the below of buffering hopper is connected with burnt water separator, a large amount of decoking water is isolated and inflow filter herein, coke enters belt conveyer, carrying device, and two coke drums share a cover system.The advantage of the method is to have realized instant Integral sealing and carries, and coke is no longer detained, and has saved floor area.Its shortcoming one is: two coke drums share a cover system, and in system, any one link goes wrong, and will directly have influence on hydraulic decoking plan, and remote effect arrive the feed time of next tower residual oil, and then has influence on the normal operation of whole delay coking process device; Shortcoming two is: from prebreaker to hopper again to burnt water separator, belt conveyer, the layout that need to superpose in the vertical direction, at the bottom of required tower, relative level is greater than absolute altitude at the bottom of conventional coke drum, overall height dimension strengthens.
