Technical field:

The utility model belongs to thermal energy conversion and environmental protection technical field, and in particular to one kind is for high molecular waste heat The stove and its high temperature combustors that can be converted.

Background technique:

Currently almost in the world, the environmental pressure of macromolecule debirs is all very big.China's macromolecule rubbish The pressure of total amount, no less than the pressure of western countries' ocean rubbish, so-called ocean garbage problem, is exactly high molecular waste thermal energy after all The technical issues of conversion.

Common macromolecular organic pollutant is derived mainly from production and life: (1) the numerous and jumbled high molecular waste of type Or organic pollutant, such as solid, liquid state and sticky state high molecular waste: plastics, rubber, paint, ink, albumen, fat, fibre Tie up element, lignite, peat, asphalitine；Multiring aromatic hydrocarbon, landing oil, foots oil, High water cut greasy filth；And copper aluminium rubber and plastic electric wire, paint Envelope curve, optical cable, electronic circuit board, CD, tape, film, aluminium foil compound packaging material, sprayed metal coating etc., via low temperature gasification The rich carbon black ionic state height volatilization diffusivity combustion gas stream that room provides；(2) coking of coal furnace or (semi-coke) carbonization at low temperature furnace, partial oxidation reactor, carbon The billowing high volatile organic pollutant of black furnace, cashew nut shell preparing active carbon furnace, black smoke；(3) coal of different component, various concentration Layer gas, shale gas, coal mine gas；(4) organic chemical industry, petrochemical industry, medication chemistry, Jatropha curcas oil, palm oil, organic spraying, Painting workshop, Yun Chao factory, printing house, epoxy resin composite material factory, electrolysis anode and cathode and asphalt modification workshop, organic matter are dry The organic pollutant of the generations such as dry baking room, (metal, inorganic and organic high molecular polymer) Hot-cleaning machine；(5) greasy filth is dirty The organic pollutant of the High water cuts such as Large Water Treatment Field, garbage loading embeading, city sewer, sewage treatment plant, farm, slaughterhouse, The contour volatilization diffusivity gas of high-speed cutting workshop coolant liquid aerosol；(6) the unburnt macromolecular of waste incinerator is organic Gas；(7) civil administration cremator and town and country pet corpse incinerate dense black smoke, volatility organic odoriferous and the underground generated The volatile coal tar etc. of flue median year accumulation.

Ground state, the kind of high molecular waste are numerous and jumbled, and the batch ingredients of each furnace investment are all changing, and can not divide one by one by furnace Analyse its molecular structure, in actual operation, or even can not its gas production of Accurate Prediction and calorific capacity, can only be by current institute's incinerated matter The states of matter of material, to determine the method for operation of vaporizer and combustion chamber.The thermal energy conversion process of solid, liquid gaseous state high molecular waste, must It is so the thermotonus in gas-phase space presentation ionic state decomposition combustion and hydrokinetic propagation process.In other words, solid, liquid Phase high molecular waste fires the gasification reaction and high-temp combustion reaction process of matter, is actually also necessarily exactly the space reaction of full gas phase Process.Upstream low temperature gasification process handles well, and the decomposition combustion for being directly related to next step high temperature gas-phase space is horizontal.

Step 3: operation low temperature gasification room, make low temperature gasification room to high temperature combustors provide different component, temperature, it is deep or light, The low decomposition level richness carbon black ionic state combustion gas stream of moisture content.

The utility model is according to the states of matter of high molecular waste and its physical property of compound, by three principle of low temperature gasification, certainly Determine the type of furnace of low temperature gasification room.Three principle of low temperature gasification specifically:

1. low temperature principle:

A, when the temperature of vaporizer is lower than 600 DEG C, the combustion gas stream of low decomposition level there is no apparent infrared light to reflect, at this time Even if there is local ion state gas to meet oxygen burning flame, macromolecular volatilization diffusivity combustion gas stream sweeps along rich carbon black in vaporizer Grain, is covered by billowing black smoke.

If b, will gasification room temperature rise to 850 DEG C ±, obvious infrared light is had in vaporizer and is seen, but its Light, caloradiance are still not enough to that certain complete decomposition combustions of macromolecular air mass can be made, and certain residual organic molecules exist in flue gas Harmful pollutant can be also aggregated into again in volatilization diffusion.It is thus impossible to by the low temperature imperfect combustion of this high molecular waste, It is eager to be defined as ' evil of the going out decrement ' of environmental protection.It is related to the thermal hardware of high molecular waste physics burning, it is necessary to cross over one further along Big step, the flameless combustion for the grade that reaches a high temperature could become the other environmental protection of high level-one and go out harmful Decrement Technique.

C, the high molecular waste of different ground state has different gasification initial temperatures, only if it were not for for the gasification rate that covets And gasification temperature is deliberately improved, respectively reasonable low temperature gasification temperature range can be set completely, such as in 100~200 DEG C, 200 The temperature range of~300 DEG C, 300~400 DEG C, 400~500 DEG C, 500~600 DEG C several class carries out preferably, best low Warm gasification temperature regulation should be within the scope of ± 10 DEG C of set temperature, and best low temperature gasification temperature is not preferably greater than 600 ℃。

2. hypoxemia principle: oxygen supply be burning necessary condition, but for low decomposition level combustion gas stream reach 850 DEG C ± When, if being also further continued for excessively supplying oxygen, it will cause not decompose completely and aggravate with low temperature imperfect combustion, remain organic pollutant Amount increases；The excessive air feed oxygenation of vaporizer, the air pre-mixing that also will have a direct impact on next step high-temp combustion close power effect.

3. low pressure principle: such as soft waste plastic, about 1 ㎡ of quality about 275~330kg ≈ volume of scrap rubber；Hard gives up phenol For urea formaldehyde or polyethylene board containing ignition-proof element: the calorific capacity ≈ II class of homogenous quantities high molecular waste thermal energy conversion overall process 1.5.~2.1 times of bituminous coal (low heat value)；Its exhaust gas volumn is estimated with this combustion heat value --- the combustion of 1/3 high molecular waste Burn the volume of exhaust gas, 2/3 high molecular waste low temperature gasification combustion gas stream volume of about >.

If this ratio continues to increase, air-inflated pressure is also increased with it in vaporizer, can be low to intentionally getting The next step air pre-mixing conjunction of decomposition level combustion gas stream causes trouble, and has an impact to further high temperature flameless combustion.

As set forth above, it is possible to referring to the high molecular waste related physical quantity of the example above, specified low temperature gasification room furnace body Volume, and reserved certain adjust space；Determine the diameter of combustion gas stream boundling mouth 31；Frequency modulation and voltage modulation performance is selected to air supply tube 38 Good air blower or wind pressure control valve.

Step 4: high temperature combustors start continuous operation, different component that low temperature gasification room provides, temperature, deep or light, aqueous The low decomposition level richness carbon black ionic state combustion gas stream of rate is collected with hundred pa grade low pressure wind speed through 10 centimeters or more of combustion gas boundling mouth 31 The combustion gas stream of the linear orientation of beam, then by combustion gas stream input port 12 enter premixer inner ring cylinder 16 inner ring in (Fig. 5 and Fig. 6 gives the structural schematic diagram of air mixer).Meanwhile middle pressure wind speed air successively passes through sending for air mixer Equally distributed millimeter fraction air holes on wind round tube 19, reducing circumference pipe 18 and step square tube 17 and premixer inner ring cylinder 16 20, then dispersion is injected in inner ring, and rich carbon black ionic state combustion gas stream and middle pressure wind speed air are pre-mixed in inner ring together, The cylindric combustion gas stream of upward vector, middle pressure power is formed after mixing.Note: step 2 intermediate fuel oil mechanism of qi bocca cooler into The summation of high temperature combustors intake when air quantity should be included in continuous operation.

Millimeter fraction air holes 20 and the lateral shaft of premixer inner ring cylinder 16 have certain angle, to guarantee premixed gas stream The force vector enhanced upwards with certain eddy flow.No special situation can not change air mixer inner ring cylinder center easily The vertical direction of line (i.e. cylindric combustion gas stream center line).

Step 5: the billowing cylindric combustion gas stream of mixed low decomposition level, the black smoke infrared optical heat radiation intracavitary in snail Under conditions of ignite, second speed, which develops, becomes that middle pressure power eddy flow is cyclic annular (arrow direction as depicted in figs. 1 and 2), and temperature is reachable 1000~1500 DEG C, make the steadily decomposition combustion of thermal-flame stream, the billowing combustion gas stream of black smoke is by middle pressure power cyclone ring second speed Anchoring, comes to naught in a moment.

Whole process can be observed by peep hole 6.If it is observed that gas concentration is too low to there is umbrella frame shape flame, combustion gas stream Temperature is low or the flow velocity that is short of power is too low, snail chamber infrared temperature too it is low ignite to catch fire difficulty and black smoke occur billow abnormal work When condition, combustion gas stream concentration, temperature, flow velocity should be adjusted immediately according to above-mentioned steps, avoids unstable decomposition, imperfect combustion.

Step 6: torch ejiction opening 10 is high-temp combustion torch cluster area, is sprayed after the burning of thermal-flame Traffic Decomposition from torch Mouth 10 provides the high-temp combustion thermal energy of industrial uses.

Step 7:, can be from supporting if necessary to detect the final result of high molecular waste thermal energy conversion after boiler flow field The detection mouth 7 of nearly torch ejiction opening 10 is detected, its flow velocity, flow, temperature change, high temperature spectrum record and fever are detected Value improves the automation of product by accumulating data.

The detection mouth 7 of the utility model can also be realized: combustion gas stream and air enter before snail chamber and combustion gas stream and empty After gas mixing, indoor temperature of burning, pressure, change in flow and the intracavitary high temperature spectrum data of snail can all be adopted by detection mouth Collection, record, and monitor operating condition in furnace.
