Abstract
The invention relates to wastes gasification based on a fixed bed pressure gasification reactor, wherein The wastes can be gasified with carbon-containingmaterials respectively or mixing with other wastes. As for the wastes of carbon-containing paste, powder and fine granular, additional preparation process can be overleaped. The outstanding advantages of this method are: Besides the ordinary loading method and conventionally performing the fixed bed pressure gasification reactor, the invention provides a feeding device to transport the wastes of carbon-containing paste, powder and fine granular directly into the gasfication area which has the highest temperature of the fixed bed pressure gasification reactor. Moreover, The wastes are transported into the area with highest temperature at a certain height, which is carried out at operating pressure by preferably two or three feeding take-overs arranged as surrounding the reactor.
Description
The present invention relates to waste gasification, particularly the field of the waste gasification in the fixed bed pressure gasification device.Refuse to be gasified is carbonaceous and has paste, a pulverous and fine grain characteristic, and these refuses can be individually or used in the mode of the mixture of these materials.
In the past, for these pastes, pulverous or fine grain refuse is conveyed in the fixed bed pressure gasification device respectively or with hybrid mode, has proposed the whole bag of tricks.All these known suggestions all are following carrying out, and are about on the material bed (Sch ttung) that above-mentioned refuse joins fixed bed pressure gasification reactor top.Propose coal tar-solid-water-mixture of being generated by coal in the fixed bed pressure gasification method and be transported to the surface of gasification materiel bed by being placed in e Foerderanlage in the intermediary raw gas outlet duct of reactor top in DD241609, this mixture generally produces with the form of inseparable stabilized emulsion.The mode of movement of this coal tar-solid-water compound facts have proved and not be effectively, especially when the reason for efficient, when reactor uses the material bed that is sunk to operate.For the internals of mechanical skill and the feeding cycle of gasification substance weak point is arranged at this, as hot ununiformity, the dislocation of jet hole (Versetzung), the especially dislocation of gasification materiel bed.As everyone knows, exactly in the fixed bed pressure gasification device, in order to ensure preferably and more stable flow condition and the distribution of a spot of dust that requiring vapour is grain pattern.
Confirm according to the trial run of DD241609, just can form logistics corridor, the dust distribution that has improved is taken away together with raw gas by local overcooling and dislocation.Be defined as especially disadvantageously with this method in this test, the coal tar-solid-water compound of about 60% input has regenerated after gasification with a kind of mixture, and this is just additional to having been brought burden at the latter linked device of reactor.
The suggestion of the water-free relatively paste tar-dust mixture of another kind of use has been proposed in DD236343.Obtain in the waste heat boiler of these water-free relatively tar-dust mixtures after being connected fixed bed pressure gasification reactor, these mixtures are transported to the vapour transfer valve of fixed bed pressure gasification reactor under operation pressure.Arrive the reactor together with vapour from these materials here.Test shows, just the ratio that can not determine occurred at the vapour transfer valve, and these logistics continue to enter the upper strata of gasification materiel bed after being injected into reactor.
In a kind of novel method according to DE19717978C1, feed valve bottom in fixed bed gasifiers has been proposed, paste tar-solid-water compound interpolation enters in the logistics of coal-refuse-mixture, under normal pressure and/or operation pressure, the time that interpolation is carried out is feed valve to the maximum and fills and the turned letter time, the packing density that depends on the charging valve, what enter reactor at last is the solid vapour.According to this method, in order to ensure the pumping power of tar-solids-water mixture, in practicality, what require to be carried has higher oil or a water-content, and solid contents is less than 30% of described mixture.Yet owing to lack gasification condition, make solid materials bed partial failure at the upper area of this solid materials bed, thereby the vapour that causes being transported can not be by trans-utilization.
Another kind of known solutions is; with additional preliminary step such as granulation or briquetting and refuse paste, dust-like or fine grain is transformed into solids; for make these pastes, dust-like or fine grain refuse burning-or gasification installation in can utilize economically, other refuse of part or even coal also must add.Yet additional preliminary step makes each utilize process cost to improve.
Purpose of the present invention and task are, carbonaceous paste, dust-like and fine grain refuse, especially extraordinary refuse, respectively or be transported to the gasifying process of fixed bed pressure gasification reactor with mixing, do not need additional preparation or preproduction phase, so just utilized waste gas economically.
According to the present invention with following this task of finishing, carbonaceous paste, dust-like and fine grain refuse, its granularity can gather after the supply in the storing unit between 0 to 4 millimeter.This storing unit is equipped with that indifferent gas floods and waste gas purification apparatus.Above-mentioned refuse, especially dust-like from storing unit, be transported to the lubricant section with fine grain refuse.The solids pump that is provided with after this lubricant section will be pressed into above-mentioned refuse the height in the gasification zone under the temperature between 1000 ℃ to 1300 ℃ in the reactor with operation pressure 25 crust (overvoltage).So just can cause the additional movement of gasification materiel bed, thereby improve the circulating capacity of material bed.
The solids pump is connected with frequency converter, and under the help of frequency converter, the power of pump can be complementary with it according to the reactor power of moving.The e Foerderanlage that comprises the solids pump, the adapter from the storing unit to the fixed bed pressure gasification reactor all are dual layings, and triple layings are better, wherein take over according to laying condition and are mounted to 180 ° or 120 °.By the temperature measuring set that install top and the following and side of carry taking over gasification is monitored, thus control paste, dust-like be approximately per hour 1 to 4 ton with the fine granular wastes input.For common approximately per hour 12 tons vapour throughput and fixed bed pressure gasification reactor, the paste of being carried, dust-like occupy 33% of the refuse that in the fixed bed pressure gasification process, is conveyed into and carbon containing vapour total amount at most with fine grain refuse by the charging valve.Pipeline is equipped with flushing and emptying is taken over, and this flushing and emptying adapter make in the containment system that seals, and for the purpose of repairing, becomes possibility and tubing system washed.
The advantage of this scheme is,
Even-reactor, also may utilize carbonaceous paste, dust-like with the mode of operation operation of the gasification materiel bed that sunk in closed system and fine granular wastes, especially extraordinary refuse,
Needn't add expensive preparatory phase before the-gasification.
-the paste that gasify, dust-like with fine grain refuse can be respectively or directly be conveyed into the gasification zone of the reactor in the highest gasification temperature scope with mixing,
-can distribute input corresponding to used reactor power.
Can more clearly illustrate according to the scheme of inventing by following accompanying drawing 1.
Carry fine granular wastes with rail transportation means 1, refuse is full of storing unit 3.Storing unit 3 usefulness rare gas elementes 4 flood, and the equipment rare gas element-and air cleaning unit.Refuse is discharged in the low pressure pipeline by impeller valve 5 in the storing unit 3, by these pipelines ejecta is transported to solid pump 7.A lubricant section 6 is installed between impeller valve 5 and solid pump 7, and randomly by adding additional lubricant, the lubricant section can be improved from the lubricity of storing unit 3 ejectas, and these additional lubricants also can be refuses.With the gasification zone 9 of mass transport to the fixed bed pressure gasification device, the operation pressure that this pressure is at least gasification installation promptly 25 clings to (overvoltage) to solid pump 7 under certain pressure.The material that gasifies is conveyed into gasification zone 9 by pressure pipeline 8.All pipelines of system all are equipped with the corresponding protection device.Solid pump 7 is connected with frequency converter, and under the help of frequency converter, the power of solid pump can be regulated with it according to the reactor power of operation and be complementary.To be on the safe side, three working barrels are installed.
