Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Synthetic gas from vapourizing furnace reaction chamber out time carry a large amount of slags and thin ash secretly, the present invention carries out classification washing, purifying by adopting multiple washing device to synthetic gas, well achieve gas solid separation, it is for subsequent use that qualified synthetic gas enters next workshop section, and slag is effectively separated respectively by other corollary apparatus with thin ash again.The present invention combines washing process as shown in Figure 1, comprising: scrubbing-cooling chamber 1; Venturi scrubber 2; Cyclonic separator 3; Water wash column 4; Heisui River recycle pump 5.First synthetic gas enters scrubbing-cooling chamber 1, then cyclonic separator 3 is entered along gaseous phase outlet pipeline 6 through Venturi 2, enter in the middle part of water wash column 4 along cyclonic separator top gas phase export pipeline 8 again, workshop section after delivering to from top gas phase pipeline 9 after 10,11 two-way washing water washings.Heisui River, water wash column middle and upper part enters scrubbing-cooling chamber 1 and Venturi scrubber 2 recycle respectively by Heisui River recycle pump 5.
Concrete technology step is as follows: the High Temperature High Pressure crude synthesis gas that vapourizing furnace reaction chamber generates and slag and carbon residue enter below scrubbing-cooling chamber 1 liquid level through downtake, Heisui River, water wash column 4 middle and upper part sprays through Heisui River recycle pump 5 and enters scrubbing-cooling chamber 1 with synthetic gas, synthetic gas 1 to cool fully in washing chamber, slag is stayed bottom scrubbing-cooling chamber 1 by Quench fragmentation, constantly discharges vapourizing furnace by lock hopper equipment; High-temperature synthesis gas is cooled to about 230 DEG C in waters, in order to avoid synthetic gas from waters out time a large amount of bubbling band water-band ash, wash cooling indoor 1 are designed with 3-5 layer and break bubble structure.In scrubbing-cooling chamber 1, crude synthesis gas well achieves preliminary grey be effectively separated thin with slag and part.Then synthetic gas enters Venturi scrubbing water cooler 2 along scrubbing-cooling chamber 1 upper gaseous phase export pipeline 6, circulating-pump outlet another Heisui River, road 14 in Heisui River enters the water distributor be embedded in Venturi 2 by flow control valve, forming an angle with gas flow is sprayed onto in synthetic gas, its speed, higher than 8m/s, forms water smoke.Water smoke and high speed synthetic gas meet, drop after atomization and between drop, sharp impacts between the soot particle carried secretly in drop and synthetic gas, soot particle is humidified, and grown up, strengthen and gaseous mass gap, synthetic gas after humidification weightening finish 7 enters cyclonic separator 3 by the road, cyclonic separator 3 import is provided with baffle plate, synthetic gas is made to rotate into cyclonic separator 3 along certain angle, first rotate downwards at cyclonic separator 3 top synthetic gas, after utilizing centrifugal force and the drop separation of growing up, synthetic gas is upwards discharged by gaseous phase outlet pipeline 8 from central rotation again, drop enters bottom container for storing liquid along wall through downtake, in synthetic gas about 80% thin ash thus be able to effective separation.Enter in the middle part of water wash column 4 from cyclonic separator 3 synthetic gas out along pipeline 8 wash further, cool, ash disposal.Water wash column 4 is tray structures, which floor is bubble-cap above, which floor is solid valve arrangement below, tower tray is respectively equipped with the high temperature buck of high temperature shift phlegma and the native system recycle returned from rear workshop section as wash spray water, synthetic gas entrance is more than water wash column liquid level, after spray water wash cooling on tower tray, discharged by water wash column 4 top gas phase pipeline 9, now synthetic gas completes workshop section's use after the rough purification of gasification workshop section is sent into, and in synthetic gas, thin ash content generally can be controlled within 5mg/m3.Vapourizing furnace scrubbing-cooling chamber 1, cyclonic separator 3, Jun You Heisui River, water wash column 4 bottom outlet line simultaneously, by the discharge that constantly circulates, washing process is sent into rear flash distillation plant because of the Heisui River removing thin ash formation process further, thus concentrate Heisui River, recovery heat, final solid-liquid separation, grey water circulation use.
Embodiment recited above is only be described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; under the prerequisite not departing from design concept of the present invention; the various modification that in this area, common engineering technical personnel make technical scheme of the present invention and improvement, all should fall into protection scope of the present invention.
