The planet speed-change boring winch that a kind of hydraulic decoking equipment is used
Technical field
The utility model relates to petroleum refining industry delayed coking unit waterpower and cuts burnt technical field, is specifically related to a kind of hydraulic decoking equipment planet speed-change boring winch.
Background technology
Delayed coking is a kind of Petroleum Processing Technology, is to be raw material with the heavy duty oil, is warmed up to the pyrogenetic reaction temperature rapidly through heating furnace, enters coke drum and carries out pyrogenetic reaction.Heavy oil carries out thermal cracking 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, boring winch, assembly pulley.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 level 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.
And boring winch is the lifting means that belongs in the hydraulic decoking mechanical system, thereby whole system provides power to drive the lifting of variable speed planetary reductor and cylinder rotation realization drilling system by motor.Boring winch also can be made the usefulness of elevator traction as moving up and down the power plant that provides at derrick for assembly pulley, high-pressure rubber pipe, drilling rod, decoking device etc. under other occasions.
At present, hydraulic decoking is the worm and gear pattern with the boring winch speed reduction gearing, because the worm-gear speed reducer mechanical efficiency is low, the specified hoisting force of single rope is less, and supporting with it pulley block ratio is bigger, and the hoisting speed of decoking device is corresponding less, cause electric energy loss big like this, the decoking time is longer.In addition in decoking process, in case the inner coke that takes place of coke drum caves in, have the bury drills phenomenon, because worm and gear boring winch hoisting force is limited, can't directly with winch decoking device be proposed from the coke of landslide, need to carry decoking device by manpower and accessory appliances, this operating process time is long, labour intensity is big.
