Description
Technical field
The present invention relates to the application of general energy technology in gas energy field, particularly relate to a kind of combustion type infrared ceramic general energy stove sheet.
Background technology
Combustion gas is as a kind of clean energy resource, and aboundresources, wide material sources, Cemented filling are convenient, cheap, brings great convenience and material benefit, generally received to living standard of urban and rural population.At present, domestic widely used combustion gas mainly contains Tian Ran Qi ﹑ Yeization Qi ﹑ Mei Qi ﹑ biogas etc.Gas kitchen ranges combustion system supporting is with it mainly air suspended type and infrared-type.Infrared ray gas range is comparatively general abroad, and start late at home, popularity rate is not high, but uses comparatively early as stove.Because of infrared kitchen range have efficiently, energy-saving and environmental protection, the feature such as safety, domestic each gas kitchen ranges factory drops into commercial city the development that people ﹑ wealth ﹑ thing carries out product energetically.
Atmospheric gas kitchen range, according to existing national standards, thermic load 3.8 ~ 4.0kw, thermal efficiency value >=55%, CO emission≤0.05%.The subject matter that current atmospheric gas kitchen range exist is:
(1) fuel gas buring is insufficient, in the bottom of a pan face easy Ji Tan ﹑ fouling, has a strong impact on heat conductivity, waste combustion gas;
(2) flame is long, affects greatly by environment gas speed, and heat transfer directionality is not strong, and area of dissipation is large, and heat loss is many;
(3) the bottom of a pan area Tan ﹑ burns and insufficient etc. causes air and the environmental pollutions such as Yi Yangization Tan ﹑ Liuization Wu ﹑ oxynitrides;
(4) although combustion gas spreads over the burning of face, the bottom of a pan, eventually because of many composite factors such as Ji Tan ﹑ Jie Gou ﹑ ambient influnences, cause the combustion gas thermal efficiency not high, efficiency is low;
Infrared gas kitchen range, according to existing national standards, thermic load >=3kw, thermal efficiency value >=50%, CO emission≤0.05%.The subject matter that current infrared gas kitchen range exist is:
(1) although thermic load is little, the thermal efficiency is not high, and efficiency is low, and thermal efficiency is generally about 50%.
(2) could not the catalytic combustion mode of radical change combustion gas, though there is directionality, caloradiance is inadequate, and infrared ray is of poor quality, and heat leak ability is weak.
(3) life cycle is short, generally will reduce at 6 months ~ 1.5 years gradually or lose infrared function.
Along with the development of national economy, moving forward steadily of industrialization and urban-rural integration, China's energy availability and demand contradiction highlights increasingly, and environmental pollution situation is also increasingly sternly completed.Along with the pay attention to day by day of people's environmental pollution and energy shortage problem, how to improve thermal efficiency value during fuel gas buring, improve heat " efficiency ", economize energy, reduce combustion product NO ﹑ CO etc. and cause environmental pollution, become the focus of people's research.The energy form that " new forms of energy " are converted into " efficiency " is presentation, " efficiency " is current is after charcoal energy, nuclear energy, wind energy, the large energy of solar energy four, commands again " the fifth-largest energy " on the large energy of Yu Si." efficiency " is own, has become the most important thing of energy innovation." general can " be a kind of efficiency new technology of system energy.Realize the maximized method of system energy service efficiency, be called " general energy technology ".Catalytic combustion is considered to the most effective approach improving efficiency.For combustion of natural gas: methane is the most stable hydro carbons, usually activation or oxidation is difficult to, and methane catalytic combustion operating temperature is higher, a large amount of steam can be produced in combustion reaction process, contain a small amount of sulphur in natural gas, therefore, methane catalytic combustion catalyst must possess higher activity and higher hydrothermal stability simultaneously, and certain anti-poisoning capability, and catalyst activity and stability are contradiction usually.Numerous scientific research personnel has carried out a large amount of correlative study, and achieves certain achievement, and the preparation and property about methane catalytic combustion catalysts more report, and what research was more at present is the noble metal catalysts such as Pd, Pt, Rh, Au.Though noble metal catalyst has good low temperature light-off performance and catalytic performance, expensive, heat endurance is relatively poor, easy-sintering, and its application is subject to a definite limitation.
Summary of the invention
For current gas kitchen range Problems existing, the present invention is solved by following approach and avoids physical thermal to lose, and is absorbed by the heat discharged as far as possible during fuel gas buring by by the object heated.Concrete technical scheme is:
The specific area of a, increase combustion type infrared ceramic general energy stove sheet, namely increases micropore, even heat is distributed, and externally concentrate release;
B, because stove sheet specific area is large, increases the contact surface of combustion gas and catalyst, adsorbent, achieve catalytic combustion;
C, under the state of catalytic combustion, improve burning velocity, reduce burning time, shorten combustion process, the heat energy that discharges of burning is more concentrated, and temperature is higher, and firepower is more violent;
D, burning velocity change the wavelength of heat energy, increase caloradiance, improve the transmission speed of heat energy, make heat energy have more directionality and the penetration to heating object, decrease heat loss after improving;
E, combustion type infrared ceramic general energy stove sheet is based on heat radiation, and convection heat transfer' heat-transfer by convection is auxiliary, meanwhile, does not lose again the spreadability to heating object surface;
The coverage of f, regulation stove sheet and heating object, general 10 ~ 30mm.
Simultaneously, the present invention also selects special metal oxide by deep researching and analysing with great many of experiments, comprise rare-earth oxide as catalyst, being aided with specific natural inorganic material is carrier, and select suitable adsorbent, by high-temperature firing preparation cost invention combustion type infrared ceramic general energy stove sheet, realize the specific area of catalyst, the good cooperative effect of activity mutually and between carrier.The present invention realizes combustion type infrared ceramic general energy stove sheet by above mode reach efficiency extreme value.
The present invention is by the application of general energy technology in gas energy field improved for the purpose of efficiency.
The first object of the present invention there is provided a kind of combustion type infrared ceramic general energy stove sheet.For realizing this goal of the invention, the invention provides following technical scheme:
A kind of combustion type infrared ceramic general energy stove sheet, 100 parts of meters by weight, fill a prescription as follows: catalyst 10 ~ 20 parts, 8 ~ 12 parts, adsorbent, surplus are carrier.
Wherein, described catalyst is selected from least one of cerium oxide, lanthana.
More preferably, also aluminium oxide is comprised in described catalyst.
Described adsorbent is selected from least one in Emathlite, diatomite, activated carbon.
Described carrier is selected from least one in mullite, clay.
Combustion type infrared ceramic of the present invention general energy stove sheet, described potsherd is circular, and it is of a size of: diameter 50 ~ 190mm × thickness is 8 ~ 16mm; Each potsherd there is perforate 1000 ~ 10000/sheet; Aperture is 1.0 ~ 1.5mm.
When combustion gas is liquefied gas, the aperture of pottery general energy stove sheet perforate is 1.1mm;
When combustion gas is natural gas, the aperture of pottery general energy stove sheet perforate is 1.35mm;
When combustion gas is coal gas, the aperture of pottery general energy stove sheet perforate is 1.5mm;
When combustion gas is biogas, the aperture of pottery general energy stove sheet perforate is 1.5mm.
Simultaneously, the present invention's pottery general can described in stove sheet carrier mullite, clay and Adsorbent Acidity carclazyte, diatomite, activated carbon in sintering procedure, there will be uncountable micropore, make pottery general energy stove sheet have higher specific area and gas sorption ability.
When gas-cooker uses, open burnt gas switch, combustion gas enters in stove pipe, can bring primary air into by gas flow rate injection, is air mixture with combustion gas mixing.Can auxiliary air be brought into by air mixture flow velocity injection, again mix.Because monoblock stove sheet is filled with uncountable micropore, specific area is very large, mixed air mixture is under the promotion of high pressure mixing combustion gas again, when passing the perforate of pottery general energy stove sheet, perforate and the micropore of potsherd can be full of with the mode of diffusion and the mode of micro-porous adsorption, make monoblock stove sheet enrichment air mixture.During igniting, about 3 ~ 5mm Lan Se flare can be lighted in the unilateral top of monoblock stove, and the unilateral top of stove starts nature air distribution (third time air) fired state.In 3 ~ 5 seconds subsequently, monoblock stove sheet surface starts rubescent, enters stove sheet catalytic combustion normal condition, and flare disappears (nonflame).After stove sheet and air mixture enter normal catalytic combustion state, stove sheet surface upwards presents a slice hunting pink (visible ray of red inner whiting) in 2mm protrusion decorative pattern position highly.Record through sensing temperature measurer, the surface temperature of luminous site reaches more than 1300 DEG C.In black, this spot temperature is less than 500 DEG C at the unilateral upper protrusion decorative pattern 2mm of stove downward stove sheet position (stove sheet true qualities).Under normal combustion state, the length of flame can be realized by the air door regulating Hybrid mode jet-flow to bring auxiliary air amount into.The length of flame is good with 0 ~ 20mm, and flame color is light orange colour, very thin, not easily sees.
The condition of burning indispensability is combustible (all oxidizable species), combustion-supporting material (oxidant) and burning things which may cause a fire disaster (can provide certain temperature or heat).Lack any one in three key elements, burning just can not occur.For ongoing burning, as long as fully control any one in three key elements, burning will stop.
Combustion process.The stages such as the burning of any combustible is generally all experienced oxidation Decomposition, caught fire, burning.Chemical compound gas such as combustion of natural gas also needs through decomposes and oxidizing process.
The burning of combustible is generally carry out in the gas phase.The state of combustible is different, and combustion process is also different.The most easy firing of gas.Heat required for burning only for the oxidation Decomposition of gas, and makes it reach ignition point, and gas just can whole after-flames in very short time; Liquid, under burning things which may cause a fire disaster effect, first flashes to steam, then oxidation Decomposition, takes fire.Compared with gas combustion, liquid (liquefied petroleum gas) burning can consume heat of evaporation liquid being become steam more; Solid combustion has two kinds of situations: for the simple material such as sulphur, phosphorus, first melt when being heated, and is then evaporated to steam and takes fire, without decomposable process; For compound substance, when being heated, first resolve into its part, generate gaseous state and liquid product, then the vapor ignition burning of gaseous products and liquid product.
Burning is chemical reaction.Burning is a kind of oxidation reaction of emitting light and heat that combustible and combustion-supporting material oxygen or other combustion-supporting materials occur.The oxidation reaction of simultaneously emitting light and heat is only had just to be defined as burning.Homogeneous combustion refer to the combustion reaction between combustible and combustion-supporting material be same mutually in carry out.The burning that fuel gas and combustion-supporting gas are pre-mixed, then carry out is called mixed combustion.Mixed combustion speed is fast, temperature is high, and general explosive reaction belongs to this form.In diffusion combustion, because the amount of oxygen contacted with fuel gas is on the low side, usually can produce unburnt carbon black.Traditional atmospheric gas burning is diffusion combustion.
The activation energy of burning is theoretical.Burning is chemical reaction, and the necessary condition of intermolecular generation chemical reaction collides with each other.At standard conditions, 1dm
3in volume, molecule collides with each other about 1028 times/s.But the molecule of not all collision chemical reaction can occur, the molecule only having minority to have certain energy collides with each other and just can react, and is called effective collision, and these a few molecules are called anakmetomeres.The energy of anakmetomeres exceeds certain value than molecule average energy, and this certain value is called activation energy.When naked light contact combustible, moieties obtains energy becomes anakmetomeres, and effective collision number of times increases generation combustion reaction.Such as, the activation energy of oxygen atom and H-H reaction is 25.10kJmol
-1, 27 DEG C, 0.1MPa time, effective collision be only collision sum 100,000/, can not combustion reaction be caused.And when naked light contacts, anakmetomeres increase, effective collision number of times greatly increases and combustion reaction occurs.
The peroxide of burning is theoretical.In combustion reaction, first oxygen formed peroxide bridge-O-O-under heat energy effect by activating, and combustible and peroxide bridge add and become peroxide.Peroxide is unstable, being heated, clashing into, under the condition such as friction, easily decomposes even burning or blast.Peroxide is strong oxidizer, can not only be oxidized the material forming peroxide, also can be oxidized other more dysoxidizable materials.As the combustion reaction of hydrogen and oxygen, first Hydrogen Peroxide, then hydrogen peroxide and H-H reaction generates water.Reaction equation is as follows: H
2+ O
2→ H
2o
2
H
2O
2+H
2→2H
2O
Organic peroxide can be considered the derivative of hydrogen peroxide, one or two hydrogen atom namely in hydrogen peroxide H-O-O-H replace by alkyl, generate H-O-O-R or R-O-O-R '.So the peroxide initial product that to be combustible oxidized, be unstable compound, very easily burning or blast.As distill ether residue in often cause spontaneous combustion or blast owing to forming ethyl peroxide.
The chain reaction of burning is theoretical.In combustion reaction, interacting between gas molecule, is not often that two molecules directly react, but bioactive molecule free radical and intermolecular reaction.Bioactive molecule free radical and another molecular action produce new free radical, and new free radical participates in reaction rapidly again, so continue and form a series of chain reaction.Chain reaction is divided into straight chain reaction and chain reaction two type usually.
The feature of straight chain reaction is, when free radical and valency saturated molecular reaction, activation energy is very low, only generates a new free radical after reaction.The reaction of chlorine and hydrogen is typical straight chain reaction.In the reaction of chlorine and hydrogen, as long as introduce a photon, just can generate up to ten thousand hydrogen chloride molecules, this is just because of the result of chain reaction.The reaction of hydrogen and oxygen is typical chain reaction.The feature of chain reaction is, a free radical can generate more than one free radical activity center.Any chain reaction is formed by three phases, i.e. the initiation of chain, the transmission (comprising branching) of chain and end stopping of chain.
Ignition temperature.The combustible heat produced that burns discharges in flame burn area, and namely flame temperature is ignition temperature.
Burn rate.Gas combustion without the need to as solid, liquid through the process such as fusing, evaporation, so gas combustion speed is very fast.Burning of gas speed is different with material composition difference.Elementary gas as the burning of hydrogen only need be heated, the process such as oxidation; Chemical compound gas as the burning of natural gas, acetylene etc. then need through being heated, decomposing, the process such as oxidation.So the burn rate of elementary gas is faster than chemical compound gas.In gas combustion, diffusion combustion speed depends on gas transmission rate, and mixed combustion speed then depends on chemical reaction rate own.Therefore, under normal conditions, mixed combustion speed is higher than diffusion combustion speed.Burning of gas performance often characterizes with rate of flame propagation, and rate of flame propagation is sometimes also referred to as burn rate.Burn rate refers to the speed that the flame of burning surface is propagated along the direction perpendicular to surface to unburned part.Under most fire or explosive event, fired with unburned gas all in motion, burn rate and rate of flame propagation are not identical.At this moment rate of flame propagation equal burn rate and mass motion speed and.
Catalyst combustion reaction.When the air mixture of low temperature flows through perforate and the micropore of stove sheet, air mixture absorbs the heat of stove sheet release in a large number, obtains the activation energy required for air mixture molecular breakdown.And the existence of catalyst, reduce the activation energy of air mixture molecule, make the bond fissions such as intermolecular O=O, C-H, C-C, form free free radical, as-O-,-H-,-C-etc., be enriched in catalyst surface, form state of aggregation.Under air mixture pressure promotes, the state of aggregation free radical that dissociates departs from stove sheet passage and micropore, carries out oxidizing fire, and focus on the release of light and heat energy on stove is unilateral.In whole combustion process, catalyst is under the acidic materials such as oxygen, Determination of Trace Sulfur existent condition, and the valency that can realize catalyst becomes circulation, makes air mixture compound molecule in stove sheet under catalyst action, complete be heated, decompose, the process such as oxidation, realize catalyst combustion reaction.
(combustion gas such as coal gas) ﹑ biogas is the mist of complicated to it Ran Qi ﹑ Yeization Qi ﹑ coal gas.Each combustion gas is all based on organic gas, be aided with inorganic matter Qi Ti ﹑ simple substance molecular gas etc., composition mist, as mixtures such as: Wan Ting ﹑ Xi Ting ﹑ Fang Ting ﹑ Chun ﹑ Quan ﹑ Tong ﹑ Liuization Wu ﹑ carbon monoxide, water, Dan ﹑ oxygen, it is the minimum gas composition difference that each combustion gas is aided with.Fuel gas buring is an oxidizing process, the power of bonding force in combustion gas molecule, determines the size of its burning time institute's energy requirement.Activation energy needed for the weak burning of bonding force is low, and burning velocity is fast, and easily form firepower and concentrate, during burning, flame temperature is relatively high, and heat power is large, and thermal effect is high.Otherwise the strong burning velocity of bonding force is slow, and firepower is not concentrated, and flame temperature is lower, and heat power is little, and thermal effect is low.For the one matter in gas only or combustion gas, need the combustion gas molecule activation energy reduced in combustion process, improve combustion speed, strengthen thermal effect, the material reaching optimum efficiency corresponding is determined, kitchen range material easily screens.But a certain material or a few material relatively determined all combustion gas be to be common to, the optimum material proportion and the best combustion effect that realize pottery general energy stove sheet are just difficult to.Therefore, for making above-mentioned fuel gas buring efficiency maximize, must traditional thinking mode be broken through, the various energy discharged during fuel gas buring are fully utilized, to realize combustion type infrared ceramic general energy stove sheet " efficiency " extreme value.
Realize " efficiency " extreme value and need the problem solving current gas-cooker two aspects: the chemical heat loss of combustion gas and physical thermal loss.
Chemical heat loss access is avoided to be as far as possible combustion gas is converted into CO by combustion reaction
