Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
In the present invention, when not making contrary explanation, the noun of locality used is as " upstream, downstream, being define with the flow direction of hot plasma for benchmark; additionally; wherein said carbonaceous material can be solid-state, liquid and/or gaseous material, it is possible to selected from coal, coal tar, coal directly-liquefied residue, heavy slag pool, Jiao, petroleum coke, oil-sand, shale oil, carbonaceous industrial waste or tailing, biomass, synthetic plastic, synthetic polymer, damaged tire, Municipal solid rubbish, Colophonium and/or their mixture.Described hot plasma body can be hydrogen, nitrogen, first a heatable brick bed and/or noble gas etc., and is produced by the plasma generator that input power is 10kW～20kW.It addition, the reaction temperature in reactor can in the middle of 1500K-4000K in the present invention, the preparation technology to enable to such as acetylene is normally carried out.
First, as the design of the present invention, the present invention provides the decoking of a kind of heat plasma reactor according, and this decoking includes the execution aeration step when reactor works, in this aeration step, pass in this reactor and can react to decompose the reacting gas of this coking material with coking material.Therefore, decomposing this coking material by entering the reaction of reactor body reaction gases and coking material, thus effectively removing the coking being attached on reactor wall, and method is simply ingenious and is easily achieved.Wherein in a preferred embodiment of the invention, decoking provided by the invention is applied to use in the technique that hot plasma prepares acetylene, treats that cracking material is carbonaceous material, for instance coal.Therefore, the coking material of generation is carbonaceous coking material (C), and for this type of coking material, the reacting gas used in the present invention is preferably carbon dioxide (CO2) or steam (H2O)。
The chemical reaction being directed to is: CO2+ C=CO；And H2O+C=CO+H2。
When adopting carbon dioxide as reacting gas, high temperature carbon dioxide electric arc can be produced, and carbon dioxide produces CO-and O-group under the effect of heat plasma bromhidrosis, this CO-and O-group can react generation carbon dioxide with the coking material on reactor wall, thus the coking material removed in reactor.So, decapacitation is enough decomposed outside coking material, additionally it is possible to obtain the carbon monoxide with surcharge, thus the value of the additional elevation present invention.In above decoking process, it is possible to substitute carbon dioxide with steam.So, under the effect of the plasma of Gao Han, steam ionizes, it is possible to the carbonaceous coking material generation water gas reaction in reactor.The coking material of so equally possible removing inside reactor, and also the hydrogen and the carbon monoxide that have added value can be obtained.
It is understood that in other embodiments, those skilled in the art are also contemplated that other gases that can react with carbonaceous coking material are as the reacting gas in the present invention.Additionally except being applied to during the carbonaceous coking material that carbonaceous material cracking produces decomposes, decoking provided by the invention can also be applied to the decoking of other heat plasma reactor according, and according to the different reacting gas of the Specific disposition of this coking material.For the application of above-mentioned different reacting gas, as long as the purpose of the present invention of being capable of, namely for the decoking in reactor, all should drop in protection scope of the present invention.
Wherein, owing to the coking of burnt body needs a process, therefore to more efficiently use reacting gas, in a kind of optimal way of the present invention, when heat plasma reactor according works, aeration step is performed off and on.The time of this interval can be designed according to the gas detecting result of reactor outlet or other empirical values, and the present invention is without limitation.Such as when using online spectrometer analysis product component, illustrating when the concentration of carbon dioxide rises to 90%, coking material is substantially clear clean, now can suspend aeration step, then again perform aeration step after separated in time.
In addition, it is different from the method that above-mentioned interval performs aeration step, devoke mode as another kind, when described reactor works, continuously perform aeration step and stop coking material to be attached on reactor wall with the successive reaction by described reacting gas and described coking material.Namely above-mentioned step decoking is in that to remove the coking material being already attached on reactor wall emphatically, and in the present embodiment, by reacting with coking material continuously, it is possible to remove it before coking material is attached to reactor wall, and stop it to be attached on reactor wall.Wherein, no matter which kind of decoking is all capable of the purpose of the present invention.
Specifically, in the described aeration step performed off and on, in order to effectively remove the coking material being already attached on reactor wall, reacting gas can be controlled to pass in reactor body in the way of high flow, for instance the 10%-200% that described reaction gas flow is hot plasma flow can be controlled.So can the coking material that adhered to of fast decoupled by the reacting gas of big flow.
The difference is that, in the described aeration step being consecutively carried out, due to be coking material be contiguous therewith before attachment reaction device inwall reaction, described reacting gas can be controlled pass into continuously in reactor body in the way of relatively low discharge, for instance control the 0.5%-5% that reaction gas flow is hot plasma flow.So, the attachment of tissue coking material can not only be met, but also the consumption of reacting gas can be saved.
The decoking above-mentioned in order to realize the present invention, as shown in Figures 1 to 4, the present invention also provides for a kind of heat plasma reactor according, including reactor body 1, this reactor body 1 is provided with hot plasma entrance 11, reaction raw materials entrance 12 and product exit 13, wherein typically, as described in Figure 1, hot plasma entrance 11 and product exit 13 lay respectively at the contrary upstream and downstream two ends of reactor body 1, therebetween axially extended reaction channel is formed, its inwall is generally of circular cross-section, and namely reactor body 1 is formed as tubular structure.It addition, the reaction raw materials entrance 12 adding the reaction raw materials such as such as coal can be formed on the sidewall of reactor body 1, and connect feed pipe 3.Wherein this feed pipe 3 can be connected on the outer wall of reactor body 1, can also by the inwall of the through hole insertion reaction device body 1 on the sidewall of reactor body 1, and the number of reaction raw materials entrance 12 can be one, two or more, and the present invention is without limitation.In order to realize the purpose of the present invention, in the present invention, reactor body 1 is additionally provided with reaction gas inlet 14, when heat plasma reactor according works, by this reaction gas inlet 14 to passing in reactor body 1 and can react to decompose the reacting gas of this coking material with coking material.Thus realizing the decoking that the present invention is above-mentioned.
