Abstract
The invention discloses a high-efficiency energy-saving water gas purification device. The device comprises a cyclone separator and a washing tower. A feeding inlet of the cyclone separator is provided with a mixer and a gas outlet of the cyclone separator is communicated with the bottom of the washing tower by a pipe. The feeding inlet of the cyclone separator is provided with the mixer, after a mixing washing process based on the mixer, a material is fed into the cyclone separator and is separated, the separated material is washed by the washing tower in a bubbling-type contact way, coal gas deep purification is realized by multistage purification so that ash content of the purified gas is less than 1mg/m<3>, and all the components have the characteristics of simple structure and large operating flexibility so that equipment maintenance convenience is guaranteed and stable long-period operation is realized. The high-efficiency energy-saving water gas purification device is suitable for preliminary purification of gas produced by gasification bed-based gasification.
Description
Technical field
The present invention relates to chemical field, especially a kind of high efficiency energy saving water gas treating plant.
Background technology
Coal gasification, especially high pressure, Large Copacity entrained flow bed gasification technology, show the economic and social benefit that it is good, represent development trend, is now the most clean coal utilization technology.The coal gas that gasification of coal is produced can be used for the production of electric power, steam, coal-based chemicals (synthetic ammonia, methyl alcohol, alkene etc.), hydrogen etc., but the production of these products proposes strict requirement to gas purification.If band ash is serious in synthetic gas, so not only affect the work-ing life of heat-transfer effect and equipment, and wearing and tearing and the blocking of pipeline, waste heat boiler and interchanger can be caused, while also serious pollute physical environment; Thin ash in addition in water-gas, water smoke are very easily adsorbed on catalyst surface, make catalyst activity reduction so that have a strong impact on production, thus causing great financial loss.The rough purification of coal gas is necessary is also necessary, and in the target bit water-gas that it will reach, dustiness is less than 1mg/L.
Gasifier bed gasification technology mainly divide with Texaco be representative COAL-WATER SLURRY TECHNOLOGY and take SHELL as the dry pulverized coal technology of representative, and the purification of raw gas is divided into dry cleaning and wet purification according to technique, wherein dry powder gasification adds wet purification because adaptation coal is wide, good in economic efficiency, the advantages such as facility investment is few become the Main way of Coal Gasification Technology development in recent years, but dry coal powder gasification, because the thin ash produced in gasification is more, proposes high requirement to water-gas washing system.So, from the needs of the reliable and stable operation of system long period, in the urgent need to a kind of less energy-consumption, good purification and the large coal gas rough purification method of turndown ratio.
Summary of the invention
The object of the invention is: provide a kind of high efficiency energy saving water gas treating plant, its less energy-consumption, high purification efficiency, to overcome the deficiencies in the prior art.
The present invention is achieved in that high efficiency energy saving water gas treating plant, comprises cyclonic separator, washing tower, and the opening for feed of cyclonic separator is provided with mixing tank, and the air outlet of cyclonic separator is communicated with the bottom of washing tower by pipeline.
Described mixing tank is the structure of Venturi tube, is provided with swirler therein.
Described washing tower is tray column, is followed successively by spiral board, column plate and reservoir composition from top to bottom.
Owing to have employed technique scheme, compared with prior art, employing is provided with mixing tank by the present invention on the opening for feed of cyclonic separator, after utilizing mixing tank to carry out mixing, washing, delivered in cyclonic separator by material and be separated, the mode that recycling washing tower carries out bubbling contact is washed, the mode of stage purification, achieve the deep purifying of coal gas, guarantee to purify ash content < 1mg/m in rear coal gas
3, and each integral part all has structure is simple, turndown ratio is large feature, convenient to guarantee maintenance of equipment, stablize long-period stable operation favourable, being applicable to the rough purification for gasifier bed gasification generation coal gas.Structure of the present invention is simple, and with low cost, result of use is good.
