Abstract
The utility model discloses a rapid cooling system for a heat exchanging tube nest in a Fischer-Tropsch synthesis reactor. The rapid cooling system comprises an upper-section steam drum circulating water pump, a lower-section steam drum circulating water pump, a heavy oil spraying pump, a Fischer-Tropsch synthesis reactor and a heavy oil spraying system soft water station, wherein a desalination water pump is arranged in the heavy oil spraying system soft water station. The rapid cooling system has the advantages as follows: through the adoption of the rapid cooling system, when the Fischer-Tropsch synthesis reactor stops working for maintenance, the Fischer-Tropsch synthesis reactor is cooled in a shorter time, the thorough repair of the device can be performed and completed in advance, the device can effectively come into operation in advance for 4 days, and 2160 tons of oil can be additionally produced in four days by taking 540 tons of oil as the average output per day (540*4=2160), so that time is saved for production, and the economic benefits are increased.
Description
Technical field
The utility model relates to a kind of heat exchanging pipe fast cooling system, particularly relates to the inner heat exchanging pipe fast cooling of a kind of Fischer-Tropsch synthesis device system.
Background technology
When the shut-down (breakdown) mainteance in the past of Fischer-Tropsch synthesizer, owing to having a large amount of high temperature deaerated water in the inner heat exchanging pipe of Fischer-Tropsch synthesis device, because heat exchanger is that height enters to exceed vertical heat exchanger, this part deaerated water can not be discharged, therefore Fischer-Tropsch synthesis device cooling difficulty.Device is in the time of parking maintenance, and temperature drops to setting can open manhole maintenance.But Fischer-Tropsch synthesis device is designed to nature cooling, needs under normal circumstances just can be cooled to for 3 days maintenance safety temperature, cooling is consuming time long naturally, affects progress.
Utility model content
The purpose of this utility model is to provide the inner heat exchanging pipe fast cooling of a kind of Fischer-Tropsch synthesis device system.
The purpose of this utility model is implemented by following technical scheme, the inner heat exchanging pipe fast cooling of a kind of Fischer-Tropsch synthesis device system, it comprises epimere drum water circulating pump, hypomere drum water circulating pump, heavy oil spray pump and Fischer-Tropsch synthesis device, described epimere drum water circulating pump outlet is led shower pipe by epimere, be connected with described Fischer-Tropsch synthesis device top water inlet, described hypomere drum water circulating pump outlet is led shower pipe by hypomere, be connected with described Fischer-Tropsch synthesis device lower water inlet, described heavy oil spray pump outlet is connected by pipeline with the outlet at described Fischer-Tropsch synthesis device top, it also includes heavy oil spray system soft water station, described heavy oil spray system soft water is provided with desalination water pump in station, described desalted water pump discharge is connected by pipeline with the import of described heavy oil spray pump, described desalted water pump discharge is also led shower pipe and described hypomere with described epimere respectively and is led shower pipe and be connected.
Replace high temperature deaerated water by demineralized water and can shift to an earlier date 3 days and surrender maintenance, spray demineralized water by outside and can shift to an earlier date 1 day and surrender maintenance, can shift to an earlier date altogether 4 days and surrender maintenance, that is to say and can have more 4 day production time every year, reach the object of volume increase.
The utility model has the advantage of, while utilizing the utility model system to make the shut-down (breakdown) mainteance of Fischer-Tropsch synthesizer, shorten Fischer-Tropsch synthesis device temperature fall time, guarantee carrying out in advance and completing of device turnover job, make again device have more effective on-stream time of 4 days, press 540 tons of calculating of average product every day, four days can voluminous oil product 540*4=2160 ton, for producing the time of having striven for, increase economic benefit.
