Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of Plasma Assisted Combustion swiss roll burner.
As depicted in figs. 1 and 2, this burner is square or circular, comprise burner housing 1, combustion chamber, spiral plate type passage, upper cover plate and lower shoe, burner is sealed by upper cover plate and lower shoe, as shown in Figure 3 and Figure 4, peep hole 11 is arranged on upper cover plate, spiral plate type passage two ends are respectively inlet channel 5 and outlet passageway 4, combustion chamber is positioned at spiral plate type channel center, deflector 2 and electric discharge device 6 are positioned at entry of combustion chamber place, porous media 3 is positioned at center, combustion chamber, ozone is set at spiral plate type passage most outer shroud and adds entrance 8, at the most outer shroud relative position of spiral plate type passage, two thermometer holes 10 are set, at spiral plate type passage innermost ring relative position, two thermometer holes 10 are set, as is illustrated by figs. 11 and 12, electric discharge device 6 is formed for metal high voltage battery lead plate 12 is arranged on insulating materials 14, metal high voltage battery lead plate 12 extraction electrode draws wire 13, as shown in Figure 9 and Figure 10, it is outside that exhaust chimney 15 is connected to outlet passageway 4.Burner upper cover plate, lower shoe and each enclose between spiral plate and mutually seal, each high temperature side surface coverage heat proof material 7 in combustion chamber.As shown in Figure 7 and Figure 8, inlet channel 5 and outlet passageway 4 are variable section structure.As shown in Figure 5 and Figure 6, lower shoe center drilling, be fire hole 10, fire hole 10 inner sleeve has porcelain bushing.
Deflector 2 is installed along air-flow conduct direction in combustion chamber interior sidewall surface.Porous media 3 is by porosity and uniform pore diameter or gradually change or one or more in foamed ceramics, ceramic honey comb or flat ceramic that layering changes form, and varying aperture scope is 0.5-8mm, and porosity change scope is 0.15-0.85.
This burner is the device for a kind of low calorific value waste gas burning and utilization, and its periphery is made up of Switzerland's web-like spiral plate, and its material can be the material of heatproof temperature more than 800 DEG C.Not losing efficacy to ensure material to be in the condition of high temperature, needing at Nei Deng high-temperature region, combustion chamber wall coating cement shape heat proof material 7.When high-temperature flue gas enters heat exchanger channels, temperature can reduce gradually, and the enthalpy of cold air inlet increases along with the rising being preheated temperature, and after the enthalpy of the waste gas being originally difficult to burning process is increased to certain value, gas can maintain burning.
But have two problems to need to solve here, be first the position that flame stops.We know that premix laminar combustion flame location has directly related with gas flow rate, kind etc., and namely when speed hour, flame upstream drifts about, and when flow velocity is large, flame drifts about to downstream again.For this Switzerland's rolling burner, flame location is needed to be stabilized in the middle of combustion chamber, therefore filling porous medium 3 material layer in central combustion chamber is needed to organize heat-accumulation combustion, and because combustion chamber volume is larger, be conducive to the abundant mixed combustion of combustion gas, also make flame not easily move in passage thus burn out gas passage.When gas concentration is lower, burning condition is more severe, inserted by plasma discharge apparatus in blast tube or combustion chamber, the particle producing dissociation can play facilitation to burning, is also conducive to flame stablizing in combustion chamber.
Next is the ability of burner process low concentration gas.First consider that the amount of process waste gas can not be too little, be namely different from the size of size with microburner; Secondly because the combustion gas of low concentration is difficult to light, only have when being preheating to very high temperature and just likely burn, therefore adopt the heat exchanger channels of swiss roll structure to accomplish this point.Consider that this burner needs by initial gas-preheating to higher temperature, the heat exchanger channels therefore designed is longer, can ensure that initial combustion gas can be preheating to from room temperature the temperature that waste gas burning needs to reach.In addition, ozone for the lifting of lean combustion fuel combustion speed than many significantly under equivalent proportion and fuel-rich condition, and add plasma discharge apparatus produce particle in also include ozone, also have the particles such as O, O3, OH, CH3, H all to promote super-low calorific value burning of gas in addition, thus reduce the poor Flammability limits of gas.Burner is provided with one-level plasma discharge apparatus 6 in central combustion chamber porch, makes the gas direct ionization in combustion chamber; Establish secondary plasma discharge apparatus in inlet channel porch, initial gas is ionized in advance; Be provided with some ozone gas at inlet channel along journey and add entrance 8, ozone is directly added in burner combustion-supporting.Because the usual activity of particle after ionization is very strong; will decompose rapidly when temperature is slightly high; therefore along Cheng Kaishe, secondary plasma discharge apparatus places mouth; the installation site of concrete plasma discharge apparatus is selected according to different temperatures situation; particle after ionization is mixed with premix gas before disappearance; when preheating temperature is to relevant temperature, fuel plays chain reaction and can relatively easily occur, and promotes the oxidizing fire of fuel.In addition, ozone generator also can produce the very strong material of oxidisability, also can reach and expand the object of Flammability limits, but due to ozone more responsive for temperature conditions, will oxygen be resolved at temperature of waiting, therefore need to add at correct position just can play a role.
The metals such as high-field electrode material selection copper of the present utility model or stainless steel, structure can use flat pole, cylindrical electrode, prickle shape electrode or polygonal electrodes.The mode producing plasma can be the one of the modes such as glow discharge, corona discharge, dielectric barrier discharge, radio frequency discharge, slip arc discharge, jet electric discharge.High voltage source can be high voltagehigh frequency AC power, high-voltage pulse power source or radio-frequency power supply etc.High voltagehigh frequency ac power frequency is 50Hz-20kHz, and crest voltage is 10Kv-60Kv; High voltage high frequency bursts power pulse frequency is 50Hz-20kHz, and crest voltage is 10kV-100Kv, and pulse width is 100ns-10us; High-voltage radio-frequency supply frequency is 1-100mHz, and crest voltage is 5000V-10000V.The OH isoreactivity group that the plasma producing apparatus that the utility model uses produces has superpower reactivity, can react with the very difficult waste gas reacted under normal condition.In low temperature plasma, electron temperature is up to tens electron-volts, and gas temperature only several Baidu, this has great advantage in industrial applicability.
The structure that the utility model is filled in the porous media 3 in combustion chamber by porosity and uniform pore diameter or can to gradually change or one or more in foamed ceramics, ceramic honey comb or flat ceramic etc. that layering changes form, varying aperture scope is 0.5-8mm, and porosity change scope is 0.15-0.85.The advantage of porous media material is high heat conductance, high-specific surface area, high porosity, not only can abundant flow-disturbing, accelerate gas and vapor permeation and carry out temperature exchange, effectively the flue gas heat of having reacted efficiently can also be passed to air inlet fully, thus effectively reduce the loss of energy.
The utility model is except burner body, porous media material, plasma discharge apparatus and ozone generator, and what also need configuration has methane, oxygen and nitrogen gas cylinder, flowmeter, air distribution system, earthenware, quartz glass.The design size of burner comprises burner height, channel width, channel wall thickness, central combustion chamber's length of side, passage length, inlet, outlet bore dia, gradual change cross section vapor path length.This structural design and processing is simple, can suitability for industrialized production.
This burner body running process is:
(1) methane-air of equivalent proportion to pass into combustion chamber from inlet channel 5 and lower shoe central point fire hole 10 simultaneously and lights, and makes porous media 3 heating materials to more than 1300-1700K.
(2) methane that also final plant closure lower shoe passes into is reduced gradually, and the low heat value combustible exhaust gas that the methane concentration simultaneously reducing gradually wealthy mouth air inlet is extremely pending, the matching relationship of this process adjusting gas flow and concentration makes the flameholding heart in a combustion chamber.
(3) some plasma discharge apparatus 6 are placed in air inlet along installing as required in Cheng Tongdao, wrap up electrode extraction wire 13 by quartz material to draw lower shoe and play the effect of fixing metal electrode plate with high voltage 12, be welded and fixed the metal bosses of electric discharge device 6 simultaneously.During use, wire is connected high voltage source, by burner outer wall ground connection, so in passage, arrange region of discharge, when passing into gas, gas will be ionized.Whether adding of plasma can make the poor Flammability limits of combustion gas reduce further, therefore reduce inlet gas combustible component concentration, observe in combustion chamber and have flame to maintain; If still have flame to maintain, combustible component concentration can be reduced further; If constant temperature is reduced to flame-out, then needs the parameter such as position, discharge voltage adjusting plasma discharge apparatus 6, reduce fuel lean Flammability limits as far as possible.Or add ozone in air inlet along journey diverse location and also can reach similar object.
(4) the high temperature neat stress through burning process collected and detected its composition, investigating the completeness reacting and carry out.Enter in environment by outlet passageway 4 again, flammable, the harmful components that at this moment contain in flue gas will reduce greatly.
This burner is by the accumulation of heat effect of porous media 3 material, the heat exchange effect of helical duct and plasma free radical particle oxidation associated treatment low heat value combustible exhaust gas, make the oxidized burning of gas success being originally difficult to be utilized, also environmentally harmful combustible exhaust gas has been changed into the material of the environmental sound such as carbon dioxide, water while discharging its energy, there is the little and advantage that disposal of pollutants is low of thermal dissipation amount.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
