Abstract
The pressurized gasifying process of polynary slurry includes five steps of preparing polynary slurry, pressurizing to gasify, purifying coarse gas, exhausting cinder and processing grey water. Specifically, the slurry prepared with one or several kinds of carbon and hydrogen containing material through grinding is made to produce intense oxidation with gasifying agent in gasifying furnace, so as to produce coarse gas with CO and H2 as main components; the coarse gas is thrice washed to produce required material gas; the cinder is chilled before exhaust; and the wash produced grey water is processed through concentration, precipitation and filtering to eliminate its ash component before being returned to the system for reuse while its heat is recovered. The said technological process has wide material adaptability, high gasification index, low investment in apparatus and other advantages.
Description
Technical field
The present invention relates to the preparation method of a kind of synthetic gas, reducing gas or fuel gas in derived energy chemical and the resource clean utilization field, particularly relate to a kind of pressurized gasifying process of polynary slurry.
Background technology
As everyone knows; since the first oil crisis outburst seventies in last century; the partial oxidation process production synthetic gas or the fuel gas technology that contain hydrocarbon material progressively cause people's great attention; ever since; unremitting effort through several generations' decades; the pressurized gasification technology constantly develops and is gradually improved, and has obtained at present using widely.The widespread use at home of fixed bed, fluidized-bed, entrained flow bed gasification technology provides competent engineering experience for the progress of gasification technology.Entrained flow bed gasification technology enjoys the favor of numerous manufacturers especially because of its gasification index is good, efficient energy-saving, environmental benefit outstanding.
Entrained flow bed gasification technology has dry method pressurized gasification, wet method slip pressurized gasification technology.Dry method entrained flow gasification such as Shell technical indicator are good, receive much concern, but plant investment are big, temporarily are not used for the precedent of compound probability on a large scale; Wet method slip pressurized gasification technology, because of the preparation of its slip, carry, metering, control be convenient, can be easy to realize high-pressure gasified, equipment domesticizes substantially, the production equipment less investment is able to promotion and application on the man production equipment of domestic number.The present invention is directed to domestic Energy resources present situation, for the resource allocation that makes full use of, contain hydrocarbon thing (wherein at least a contain hydrocarbon solid) as various in reasonable conversion refining of petroleum and other production process, propose to adopt to grind the slip that gasifies fully altogether, through the air flow bed pressurized gasification, produce with CO, H
2, CO
2, CH
4Deng the synthetic gas, reducing gas or the fuel gas that are main composition.
Summary of the invention
The purpose of this invention is to provide a kind of polynary slurry gasifying process.This technology has that adaptability to raw material is extensive, gasification index is good, process unit equipment is few, plant investment is few, the advantage of easy and simple to handle and environmental protection.
The object of the present invention is achieved like this: this technology comprises polynary slurry preparation, pressurized gasification, raw gas purifying, lime-ash discharging and grey water handing five parts, promptly utilize a kind of or several contain hydrocarbon material, be equipped with slip through once grinding altogether, violent partial oxidation reaction takes place in slip and vaporized chemical in half water wall vapourizing furnace 5, generates with CO and H
2Be main raw gas, raw gas is behind three washing, purifyings, and the unstripped gas of production satisfies service requirements, after the lime-ash Quench that material gasification produces, is directly discharged by furnace bottom ash discharge slag system; The buck that washing produces is earlier after put forward dense, precipitation and filtering mode is removed the ash that it carries, the heat energy of the steam recover gray water of by-product, and treated buck can return gasification system and recycle.
Advantage of the present invention is: 1, gasified raw material wide material sources: under the effect of slip additive, by once grinding wet method slurrying altogether, a kind of polynary slurry pressurized gasification method can be transformed into the material that comprises all carbon containing protiums such as coal, refinery coke, pitch, Residual oil and contains CO, H
2, CO
2, CH
4Deng the unstripped gas that is main composition;
2, the vaporized chemical choice is bigger: according to the different requirements of follow-up system to material synthesis gas, gasification process of the present invention can select oxygen, oxygen-rich air, air etc. as vaporized chemical respectively;
3, multistage washing, synthetic gas be " totally " relatively: polynary slurry can satisfy the requirement of follow-up system to synthetic gas fully after the crude synthesis gas that the vapourizing furnace internal reaction generates washs through chiller washing, tubular type washer humidification and washing, washing tower successively;
4, process energy consumption is relatively low, the water of total system has obtained sufficient recycle: the waste water that gasification produces is sent into vapour liquid separator, mode with byproduct steam reclaims heat energy, be used to heat the buck of retrieval system, handle spissated buck through vapour liquid separator and enter settling tank, clean lime set is sent degasifier, and after precipitation and degasification, this two portions water retrieval system again continues to use;
5, owing to taked efficiently that grey water handing, lime-ash are handled, exhaust gas processing device, thereby make whole technology three wastes discharge amount drop to alap level, alleviated the pollution to environment greatly, waste water, waste residue, discharge amount of exhaust gas are little, and is good to environment.
