Description
Technical field
The utility model relates to chemical field, especially a kind of new type water gas purification equipment.
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 purpose of this utility model is: provide a kind of new type water gas purification equipment, and its less energy-consumption, high purification efficiency, to overcome the deficiencies in the prior art.
The utility model is achieved in that new type water gas purification equipment, 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 utility model 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.The utility model structure is simple, and with low cost, result of use is good.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the structure of new type water gas purification equipment as shown in Figure 1, comprise cyclonic separator 1, washing tower 4, the opening for feed of cyclonic separator 1 is provided with mixing tank 2, and the air outlet 3 of cyclonic separator 1 is communicated with the bottom of washing tower 4 by pipeline 5; Mixing tank 2 is the structure of Venturi tube, is provided with swirler therein; Washing tower 4 is tray column, is followed successively by spiral board, column plate and reservoir composition from top to bottom.
Concrete process example: the powdered coal pressuring gasified device 6 of Quench type processing 1200 tons of coals day, vapor pressure is 4.0MPa, gasification temperature is 1600 DEG C, after gasification gas goes out shock chamber's washing, temperature is 220 DEG C, synthetic gas butt flow is 70000Nm3/h, and wet basis flow is 170000Nm3/h, can slag content be 8g/Nm3 in coal gas; The gas pressure entering mixing tank 2 is 3.98MPa, and the grey water temp entering mixing tank 2 is 140 DEG C, and the water yield is 40m3/h; High temperature buck in system selected by washing water in mixing tank 2, and water-gas is through the wetting of high temperature buck and condensation in mixing tank 2, and the thin grey rapid aggregation in water-gas is grown up, and enters into cyclonic separator 1 with water-gas; Cyclonic separator internal diameter 2000mm, be highly 14500mm, by centrifugation, the dust macrobead flocked together in mixing tank 2 before in water-gas is separated in cyclonic separator 1, by in water-gas 80% lime-ash separate, lime-ash enters cyclonic separator 1 bottom reservoir, enter slag water treatment system subsequently and carry out flash distillation condensation settlement treatment, achieve and first purification is carried out to water-gas; The bottom reservoir that water-gas after purification is entered in washing tower 4 by cyclonic separator 1 upcast carries out water-bath; Washing tower internal diameter is 3200mm, be highly 22700mm, be provided with five layers of column plate, distance between column plate is 750mm, column plate water charging system high pressure buck 150m3/h, de-oxygenised water 50m3/h, go out in the coal gas of washing tower containing lime-ash 0.5mg/m3, not stifled slag, is not with water, can be good at the requirement meeting lower procedure; After water-bath washing, rise to column plate, then with after the upper liquid layer of column plate contacts step by step and carries out deep purifying, after the spiral board at washing tower 4 top, discharge lower procedure after entering into.
