Description
Technical field
The utility model relates to ethylene glycol production technical field, is specifically related to the hydrogenation workshop section heating device that synthetic gas is prepared ethylene glycol.
Background technology
Ethylene glycol is a kind of important Organic Chemicals, and traditional ethylene glycol production method is to walk petrochemical complex route, obtains ethene by refining of petroleum, uses silver catalyst that oxidation of ethylene is generated to oxyethane, then by ethylene oxide hydration generating glycol.Along with the day by day shortage of world petroleum resource, and the few Energy Situation of China's coal heavy wool, existing adopt prepared this technique of ethylene glycol with producing synthesis gas from coal and dimethyl oxalate (DMO) hydrogenation reaction more.Because dimethyl oxalate is colourless monoclinic crystal body, be solid at normal temperatures, fusing point is 54 DEG C.Flow in pipeline so need aborning to be formed liquid state, otherwise after general solidifying, can make the conveying of material stop and forcing glycol unit to be stopped work.Now many dimethyl oxalate is dissolved in and in methyl alcohol, forms the methanol solution that mass percent is 10-50%, but its methanol usage is larger, and the reaction later stage also relates to the recycling of dimethyl oxalate and methyl alcohol, has increased equipment, and can cause cost to increase and the waste of raw material.
Also there is at present the steam and hot water of employing to prevent that dimethyl oxalate from solidifying in pipeline, make it be liquid state producing in pipeline and intermediate product storage tank, and prevent that by the heat supply that the pump circulation of pump completes hot water dimethyl oxalate from solidifying.But because the investment of pump is larger, running expense is high, and as transmission apparatus, also may be because damaging or other technological reason causes and carries poor effect to affect production run.
Utility model content
For above-mentioned problems of the prior art, the hydrogenation workshop section heating device that provides synthetic gas to prepare ethylene glycol is provided the purpose of this utility model, realize low cost, expeditiously the dimethyl oxalate basin to hydrogenation workshop section and pipeline and accompany heat, prevent solidifying of dimethyl oxalate.
The technical solution of the utility model is: synthetic gas is prepared the hydrogenation workshop section heating device of ethylene glycol, comprises dimethyl oxalate basin and vaporizer, and the import and export end of described dimethyl oxalate basin is all connected with oxonation device, vaporizer respectively by trace pipe; The hot water that described dimethyl oxalate basin, trace pipe provide by injector is accompanied heat; Two inlet ends of described injector are connected with the outlet side of vapour pipe, oxonation device respectively.
Further, the outlet side of described vaporizer is connected with the inlet end of injector by pipeline.
Further, on the pipeline of two inlet ends of described injector, be equipped with variable valve.
Further, described injector comprises air-breathing section, mixing section and diffusor, is provided with spout in described air-breathing section, and the osculum end of described spout is provided with nozzle; Described air-breathing section is provided with two entrances, and air-breathing section is communicated with diffusor by mixing section, and the other end of described diffusor is provided with outlet.
The utility model makes full use of high-temperature steam that dimethyl oxalate gas heat of condensation and evaporator evaporation produce as the origin of heat of injector and for accompanying heat.The hot water simultaneously dimethyl oxalate basin and the trace pipe respectively and between oxonation device, vaporizer thereof being exported by injector is accompanied heat to them, prevent that dimethyl oxalate from solidifying, and spray the conveying that completes hot water under drive at steamer, reach uninterrupted companion's thermal effect.
On the pipeline of two inlet ends of injector, be equipped with variable valve, for regulating from vapour pipe and completing the adjusting of delivery amount and water temperature from the flow of the heat of condensation of oxonation device.
The utility model adopts injector to utilize heat in production process to produce the hot water that companion is hot, and water temperature is easy to adjust, can reach insulation and energy-conservation effect simultaneously, and injector long service life, cost are low.
Because evaporator evaporation produces a large amount of high-temperature steams, therefore except introducing steam from the external world at first its of driving, the high-temperature steam that in operational process, vaporizer produces can replace extraneous steam and pass in injector for accompanying heat needs, reduces the consumption of extraneous steam, saves energy and reduce the cost.And realize the recycle of the energy.
