Background
In petroleum processing, the delayed coking process is an important residue (heavy oil) processing procedure. The raw material is heated to about 500 ℃ by a heat exchange and coking furnace, and then enters a coke tower to carry out thermal cracking reaction and condensation reaction, and oil gas and solid coke are generated in the coke tower. Oil gas generated by the thermal cracking reaction enters a fractionating tower through an oil gas line at the top of the coke tower and is separated into rich gas and fractions such as naphtha, diesel oil, wax oil and the like. Solid coke is deposited in the coke drum and periodically decoked to the coke pool. The production of the coke tower is intermittent operation, raw materials heated by the heating furnace enter one coke tower (production tower) for coke formation, and an operator simultaneously carries out the treatment processes of blowing, coke cooling, coke cutting, air driving pressure testing, tower warming and the like on the other tower (treatment tower). Then the feeding is switched to a new production tower (an original treatment tower) through the four-way valve, the switching is repeated in such a way, the production is continuously carried out, when the coke tower is produced, the temperature of oil gas at the top of the tower is more than or equal to 440 ℃, when the oil gas flows through a large oil gas line at the top of the tower, the coking reaction is continuously carried out, the oil gas line is coked, and even the bottom of the fractionating tower is coked. The pressure drop of pipeline blockage caused by coking of the oil-gas line is increased, the operating pressure of a coke tower is increased, so that the coke amount is increased, the yield of a coking liquid product is reduced, and the economic benefit of the device is reduced. When the coking is serious, the pipeline needs to be dismantled for coke cleaning, and the normal operation and production are affected. In order to solve the problem of coking of an oil-gas line, quenching oil needs to be injected at an outlet of the oil-gas line, the oil gas is rapidly cooled to below 415 ℃, and the coking reaction is stopped.
The Chinese patent utility model with publication number CN202297497U discloses that the coke tower top oil-gas line anti-coking device mainly comprises an oil-gas pipeline tee joint, a quenching oil sleeve, a quenching oil injection pipe and an atomizing nozzle; the oil-gas pipeline tee is provided with an upper flange, a lower flange and a side flange; the flange cover of the upper flange is provided with an opening, and the quenching oil sleeve penetrates through the opening on the flange cover to penetrate into the tee joint of the oil-gas pipeline and is welded with the flange cover; the oil-gas pipeline tee joint is connected with an oil-gas outlet pipeline at the top of the coke tower through a lower flange and is connected with a horizontal oil-gas pipeline through a side flange; a pipe flange is arranged at one end of the quenching oil casing pipe exposed out of the oil-gas pipeline tee joint, and a quenching oil injection pipe is connected with the pipe flange and vertically and downwards penetrates through the quenching oil casing pipe and extends to an oil-gas outlet at the top of the coke tower along a pipeline at an oil-gas outlet; the atomizing nozzle is arranged at one end of the quenching oil injection pipe close to the oil gas outlet. The device not only can effectively prevent coking of oil gas pipelines, but also is easy to disassemble and assemble and convenient for coke cleaning.
However, the above invention and the background art have the following disadvantages:
firstly, the method comprises the following steps: the existing quenching oil is sprayed on an oil-gas pipeline in a spray head spraying mode so as to rapidly cool the oil gas passing through the oil-gas pipeline, the quenching oil is consumed in the spraying cooling mode, the contact time of the quenching oil and the oil gas in the air is short, the heat exchange efficiency is poor, and the cooling effect of the quenching oil is low;
