Abstract
A system for recovering light oil from residual ammonia water is improved based on the existing technology and comprises a residual ammonia water oil remover, an extraction tower and an ammonia still that are sequentially connected in series, wherein a steam outlet of the ammonia still passes through a condenser and a cooler and then is connected with a finished ammonia water and light oil standing separation tank; the bottom of the ammonia water and light oil standing separation tank is connected with the ammonia still by a draw-off pump and a pipeline; and a liquid indicator is arranged on one side of the exterior of the standing separation tank. The quality of the ammonia water (a stilled ammonia finished product) is improved through simplest technical change and lowest investment, and popularization and application in improving recovery of the ammonia stilling technology light oil from the residual ammonia water in other coking plants can be promoted.
Description
Technical field
Patent of the present invention relates to the technology that coal tar remained ammonia distillation and finished product ammoniacal liquor contain recovery of oil, has specifically increased the technique that reclaims lightweight oil in residual coking ammonia water in a series for the treatment of processes.
Background technology
Coal produces the remained ammonia that contains a certain amount of lightweight oil in coking, wherein ammonia nitrogen, prussiate, sulfide, phenol and COD concentration are all higher.Original technique is when delivering to remained ammonia ammonia still process workshop section and distill, and because lightweight oil belongs to light component, most of lightweight oil and ammonia together volatilize and enter the finished product ammonia vessel after cooling from the ammonia still process cat head, finished product ammoniacal liquor is sent into other posies use.But because containing lightweight oil in the finished product ammoniacal liquor, affected the use of subsequent processing, and brought potential safety hazard, and caused the wasting of resources.
Summary of the invention
In order to solve the deficiencies in the prior art, recovering of vaporized hydrocarbons system in a kind of remained ammonia is provided, before finished product ammoniacal liquor delivered to other posies outward and use, use the oily water separation facility that finished product ammoniacal liquor is separated with lightweight oil, finished product ammoniacal liquor after the separation enters subsequent processing and uses, and the lightweight oil after the separation enters purification system.Therefore, what the present invention studied is recovering of vaporized hydrocarbons system in a kind of remained ammonia, and purpose is to make remained ammonia ammonia still process product satisfy the requirement of subsequent processing, and obtains clean or white, improves the performance of enterprises.
The technical solution adopted for the present invention to solve the technical problems is:
Recovering of vaporized hydrocarbons system in a kind of remained ammonia, the remained ammonia oil eliminator, extraction tower and the ammonia still that are connected in series successively before and after comprising, it is characterized in that, described ammonia still vapour outlet is successively by being connected to finished product ammoniacal liquor and lightweight oil standing separation groove behind condenser and the water cooler, the bottom of described ammoniacal liquor and lightweight oil standing separation groove is connected to ammonia still by extraction pump and pipeline, and is provided with liquidometer in the outside of described standing separation groove one side.
Be respectively equipped with the first valve and the second valve in the junction up and down at described liquidometer and standing separation groove, and the overflow spout of described liquidometer by the bottom is connected to the lightweight oil storage tank.
Bottom at described extraction tower connects a mixture storage tank by pipeline.
In the bottom of described ammonia still by pipeline and waste water pump efflux wastewater.
Tower entrance is positioned at the ammonia still middle part.
The invention has the beneficial effects as follows:
(I) do not change former ammonia distillation process and equipment, only increases new finished product ammoniacal liquor and lightweight oil standing separation slot device and affiliated facility after former technique, just can make ammonia still process finished product ammoniacal liquor satisfy the next procedure requirement, and it is simple to reclaim lightweight oil technique, invests low;
(II) do not affect the normal operation of former ammonia steaming system;
The amount of (III) recovery lightweight oil is controlled, and can use up maximum may reclaiming, and can improve productivity effect;
(IV) removed the lightweight oil in the finished product ammoniacal liquor, is conducive to the safe handling of finished product ammoniacal liquor;
(V) is perfect to a series for the treatment of process such as residual coking ammonia water ammonia still processs, promoted the progress of residual coking ammonia water treatment process, started recovering of vaporized hydrocarbons precedent.
The present invention has improved ammonia still process finished product ammoniacal liquor quality with the investment of the most easy process variations, minimum, is conducive to promote improved the applying of other coke-oven plant's remained ammonia ammonia distillation process recovering of vaporized hydrocarbons.
Description of drawings
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the partial view of standing separation groove.
Among the figure: 1 remained ammonia oil eliminator, 2 extraction towers, 3 extract storage tanks, 4 ammonia stills, 5 condensers, 6 water coolers, 7 standing separation grooves, 8 lightweight oil storage tanks, 9 reflux pumps, 10 waste water are sent pump outside, 11 liquidometers, 12 first valves, 13 second valves, 14 level gauge glass pipes.
Embodiment
As shown in Figure 1 and Figure 2, recovering of vaporized hydrocarbons system in a kind of remained ammonia comprises that remained ammonia oil eliminator 1, extraction tower 2, extract storage tank 3, ammonia still 4, waste water sends pump 10, condenser 5, water cooler 6, finished product ammoniacal liquor and lightweight oil standing separation groove 7, lightweight oil storage tank 8 outside.By a kind of technique of obtaining the lightweight oil after the remained ammonia ammonia still process of effectively being combined to form of several large function devices.
The liquid outlet of remained ammonia oil eliminator 1 connects extraction tower 2 entrances, ammonia still 4 entrances backward successively, and waste water is sent pump 10 outside the waste liquid of ammonia still bottom is effluxed, and tower entrance is positioned at ammonia still 4 middle parts, and the mixture of extraction tower 2 extractions enters mixture storage tank 3.The air outlet at ammonia still 4 tops connects condenser 5 entrances and water cooler 6 entrances in turn, then is connected to finished product ammoniacal liquor and lightweight oil standing separation groove 7, and this groove mainly temporarily stores ammoniacal liquor and lightweight oil and both standing separation are used.Finished product ammoniacal liquor and lightweight oil standing separation groove are connected to lightweight oil intermediate storage tank 8 by pipeline.Pick out an outlet conduit at the bottom of finished product ammoniacal liquor and the lightweight oil separator tank, be connected to the ammonia still process cat head by reflux pump 9.
Finished product ammoniacal liquor and lightweight oil standing separation groove one side outside are provided with a liquidometer 11, finished product ammoniacal liquor in the standing separation groove 7 and lightweight oil are through after the standing separation, observe ammoniacal liquor and separating of oil situation by level gauge glass pipe 14, liquidometer 11 belows have an overflow weir, and lightweight oil from then on mouth overflows and immerse lightweight oil storage tank 8.
Working process is such, the remained ammonia that coke oven comes 1 is gone out the non-lightweight oil of most of organic wet goods in the remained ammonia oil eliminator, continue to enter in extraction tower 2 towers, a large amount of benzene is arranged in extraction tower 2, benzene and remained ammonia counter current contact, absorb a large amount of phenol in the ammoniacal liquor, benzene and phenols are delivered to mixture storage tank 3 after the extraction.
