Description

The separable quench ring and distribution channel of gasifying reactor
The carbonaceous fuel burning can produce synthetic gas.In gasifier or reactor, under the high temperature and high pressure condition, it is the most effective to carry out this process.For example, produce coal gas with fine coal or coke, preferably maintain about 2400 °-2600 operating temperature range, pressure is between about 5-250 normal atmosphere.
The critical operation condition that aforesaid method generally adopts particularly will stand big temperature variation, makes many parts of gasifier or reactor produce violent strain.
The present invention has done improvement to gasifier quenching ring and water distribution afflux groove especially to the gasifier structure.The latter is subjected to the influence of high temperature and harmful gases easily because its inherent function, and this is because when going out logistics and go into cooling zone or quench region from the hot-fluid of combustion chamber, hot synthesis gas directly contacts with the quenching ring.
United States Patent (USP) 4,444,726 describe removablely, and the quenching loop device of two sections designs is pressed on the lock packing between the correspondent section, can make correspondent section keep sealed relationship relatively closely.Yet, the easy heated airflow influence of sealing filler, and stand big temperature variation, this filler of these factor affecting is as the work-ing life of effective sealing element.
In common structure of reactor, refractory liner can be used in the intravital combustion chamber of reactor enclosure, to avoid the housing heat damage.This refractory materials can be used special brick, or the refractory materials of casting.In either case, refractory part or element are combinable and constitute definite shape, are used for limiting gasifier and shrink trunnion.
Fire-resistant trunnion element normally supports by this way, that is, repair if desired or change, and they can be removed.A kind of quenching intra-annular that is positioned at supports and can support trunnion, like this, and the trunnion that can be used to fixedly be supported by the localized quenching ring of shell wall.Yet, during out of service, in common process of cooling, the metal part of gasifier, for example, quenching ring and appurtenances thereof are cooling fast more likely, can carry out necessary maintenance work near inside reactor rapidly like this.
In order to repair or to change, when requiring to remove reactor quenching ring, must at first unload and form the refractory part that shrinks trunnion, but these non-metallic components just can cool down than metal quenching ring spend for more time, therefore, after some days, people could remove the quenching ring by the safety inspection inside reactor.In addition,, make spare part can not correctly ressemble (because distortion and slag stores of producing during operation), remove the trunnion refractory materials and must change the more alternative expense of expense because used refractory brick once was disturbed.
In order to overcome the problem that shut-down does not need gasifier and the fire-resistant spare part of trunnion to replace, in the gasifier structure of the present invention, contraction trunnion between combustion chamber and quenching chamber is made up of one or several refractory parts, and the latter is supported by sectional type quenching ring (removable afflux groove is arranged).Like this, because heat effect or other reasons when damaging, the parts of damage are easy to dismounting, still do not stay the quenching ring that supporting trunnion in position should be arranged and do not influence when quenching ring exposed portions serve (afflux groove).
Removable water delivery afflux groove (can make cooling liquid flowing directive reactor immerse pipe) is fixed on the water guide quenching ring.Preferred structure is between corresponding afflux groove and the quenching ring mating surface heat-resistant filler that compresses to be arranged, and this makes the hot flowage between them get minimum.Like this, during dismounting afflux groove, being defined as the heat-resistant component or the combiner that shrink trunnion can be unaffected.In addition, the heat-resistant filler between cooperation or the meshing part can make the heat passage minimum that becomes between them.
From the economic point of view, use disclosed removable quenching ring structure can make the reactor turnaround reduce some days.In order to compare, measured already, when to make things convenient for the quenching ring be typical gasifying reactor a part of, in two days, just can enter this device internal overhaul quenching ring.If fire-resistant reducing must be removed, could overhaul the quenching ring, like this, and cooling refractory materials and fire-resistant spare part is contained on the new quenching ring, spend is 5 days or more days altogether.
Therefore, the present invention seeks to provide a kind of novel quenching ring component of being convenient to remove and overhaul reactor internals for gasifying reactor.
Another purpose provides the multi-stage type quenching ring of the impaired inner part of a kind of easy access reactor.
The another one purpose is can take apart for gasifying reactor provides a kind of, and can unload the multi-stage type quenching ring of lower member from refractory materials inside.

Fig. 2 is the sectional view of Fig. 1 2-2 section,
About Fig. 1, the typical gasifier of imagination or reactor 10 have the metallic steel wall housing 11 of an elongation, and this reactor is in vertical state usually and moves, and this might flow downward hot product, and housing 11 tops comprise reaction or combustion chamber 12.In order to stand the service temperature between 2000-3000, inwall 13 linings are used in combustion chamber 12, and inwall 13 preferably is made of the refractory materials that is fit to.
Be positioned at housing 11 tops removable burner can with the carbonaceous combustion mixt (such as, fine coal or coke) spray in the reaction chamber 12 by feed source 16.From an amount of inflammable gas in high pressure feed source 17 and flow to, form the combustion mixt that requires into burner 14.
Gasifier of the present invention is the various carbon solids of incendivity equally also, liquid or geseous fuel, yet, for instant embodiment is described, suppose that burner 14 is to be communicated with coke source 16, the best precomminution of coke, and the adding enough water is made the coal slurry that requires concentration.The high pressure inflammable gas in feed source 17 is oxygen normally, air, or its mixture.
The lower end of reaction chamber 12 may be defined as downward-sloping fire-resistant bottom 18.This configuration is convenient to discharge heating gas and molten slag from reaction chamber 12.
Housing 11 low sides comprise the quenching chamber 19 that gaseous product flows into.Solid-state and gaseous product the two here contact cooling bath of liquid groove 21(form by water usually).Cooling gas is flowed into by quenching bath 21 and discharges district 26, by pipeline 22, leaves quenching chamber then.Be cooled, essentially no particulate gas is handled in next step equipment, and is processed into useable products.Solid in the effluent or slag deposition by outlet orifice 23, enter in the interlocking tank 24 in bath 21.
Reaction chamber 12 and quenching chamber 12 are that the contraction trunnion 27 by reaction chamber bottom 18 interconnects.For the hot effluent that leaves reaction chamber 12 is effectively contacted with liquid in the bath 21, quenching chamber 19 is equipped with dipping tube 29(has a top edge near shrinking trunnion 27), dipping tube 29 also comprises the lower edge that is terminated at cooling fluid bath 21, therefore, dipping tube 29 is defined as the effluent path.
About Fig. 2, shrink trunnion 27 and may be defined as the initial guide channel that the high-temperature high-pressure effluent flows through.Because hot effluent flows into water-bath 21 by trunnion 27, therefore, the inwall 28 of dipping tube 29 is that hot-fluid goes out the cylindrical guiding latus rectum of (comprising gaseous state and solids fraction) with regard to its functional definition.
The inwall of garden cylindricality dipping tube 29 or spigot surface 28 are easy to be penetrated the multiply High-Pressure Water that comes by quenching ring component 36 and get wet.
The carriage 44 that is fixed on housing 11 inwalls can be used to support quenching ring component 36.These parts 36 mainly comprise two ring segments of working in coordination 34 and 41, and removable ring segment 41 relies on the filler 56 between the section of being pressed on 34 and 41 to get in touch with fluid-tight.
More particularly, multistage quenching ring component 36 comprises first annular or major section 34, or the object of sidewall (being defined as the neighboring) is arranged.Second or inwall 39 can form fixedly that second section 41(of quenching ring is also referred to as water distribution afflux groove) sealing or mating surface.
