Connection, in parallel or connection in series-parallel composition common mode synchronized model industrial smoke resume combustion cyclic processing device.
Above-mentioned common mode synchronized model industrial smoke resume combustion circular treatment module is applied to the low of all gas fuel combustion system
Nitrogen, VOC processing.
Fume treatment process is broadly divided into：Cigarette/air is mixed to form combustion gas, fuel gas buring heat transfer, in flue gas porous media
Resume combustion, mixed flue gas export four courses of work.More specifically flue gas processing method includes：
Fuel/air mixture mixing (combustion gas) inputs the gas mixing chamber 13 from radial air inlet membranous cochlea 6, and combustion gas passes through ring-type spoke
Internal face low nitrogen burning of the hole in the ring-type radiation shield 12 of screen 12 is penetrated, tubular film flame, ring-type radiation shield 12 is formed
900 DEG C or so itself are also heated to, the oxygen gas that low nitrogen burning is produced are discharged into the second-time burning through ring-type radiation shield 12
Space 3, ring-type radiation shield 12 is simultaneously to the radiant heat of second-time burning space 3；
Meanwhile, another road backflow flue gas enters the second-time burning from air inlet 7 through a cone barrel porous media core body 2
Space 3, sprays through another cone barrel porous media core body 5 from gas outlet 8, and flue gas resume combustion in the process removes VOC；
By adjusting between the gaseous-pressure in second-time burning space 3, two cone barrel porous media core bodys 2,5 of regulation
Gap, can control smoke reaction temperature and time in second-time burning space 3, the combustible component in flue gas is reacted completely.
In preferred mode, resume combustion control mode of the flue gas in second-time burning space 3 includes：
The oxygen gas that low nitrogen burning is produced are discharged into the second-time burning space along the direction vertical with the central shaft 4
3, and smoke evacuation pressure is more than the pressure of the flue gas inputted from cone barrel porous media core body 2, makes two-way flue gas formation slipstream rapid
Mixed heat transfer；
The radiant heat that two cone barrel porous media core bodys 2,5 absorb ring-type radiation shield 12 makes its medium holes heat up, flue gas
Heat is obtained when flowing through high-temperature medium hole to react；
The gap between two cone barrel porous media core bodys 2,5 is adjusted, occurs the aerodynamic parameter in second-time burning space 3
Linear change, can pass to processed flue gas by flame radiation to greatest extent.
At least some embodiments possess advantages below：
(1) high efficiency：At a temperature of the low nitrogen burning of setting, by innovating combustion chamber porous media structure and aerodynamics
Optimization, makes combustion gas in determining the burning of reaction zone (ring-type radiation shield) low nitrogen formula.Meanwhile, set up after high excess air ratio burning
High temperature gases recirculating resume combustion flow, makes obvious heat of smoke and does not use up oxygen repetition participation subsequent combustion reaction wherein, so can both return
With fume afterheat, and the oxygen in the larger excess air coefficient of low nitrogen burning, beneficial support can be provided for its resume combustion process.
(2) high heat transfer：While tubular burner inner wall face constitutes low nitrogen burning, the flue gas come is flowed through to upstream with three kinds
Its resume combustion of mode tissue.It is that tubular burner is discharged fume by porous media ring-type radiation shield first, its direction and burner axle center
Vertically, and because the exhanst gas outlet pressure of its ring-type radiation shield is more than the backflow flue gas of axial circulation, therefore slipstream is formd
The mixed heat transfer of rapids；Next to that the backflow flue gas axially introduced will be by two cone barrel being symmetrically installed porous media core bodys, this
Porous media core body is heated by the annular radiation shield synchrotron radiation of its overcoat again, the turbulent flow flue gas containing combustibles is situated between in high temperature
More heats are obtained in matter hole and are fully reacted.The vertex of a cone of two cone barrel porous media core bodys is adjusted away from two cone cylinders can be made
Linear change, maximum limit occur for the aerodynamic parameter for filling the VOC central reactions area (second-time burning space) between radiation shield with outer sleeve
That spends can pass to flame radiation processed flue gas, complete VOC and eliminate.
(3) low NOX：In the porous media assembly of particular configuration, with changes in flow rate, combustion gas equivalent proportion is increased and set
Fixed servo interval is automatically adjusted, and makes reaction zone temperature constant on design point (950 DEG C ± 50 DEG C), forms stable low nitrogen row
Put.Ring-type radiation shield utilizes its ripple struction, and the axial force of one-way flow is provided for the flame that is sprayed from its wire side.
(4) low consumption：Flue gas resume combustion can take back obvious heat of smoke combustion zone, and wherein VOC combustibles will participate in reacting, combustion
Burn reaction zone and just form " super enthalpy " state --- i.e.：Reaction zone total amount of heat exceedes primary fuel supply institute heat content.Isothermal is defeated
Go out to be formed low consumption state.In terms of the theory of combustion, low nitrogen is begun by reduction flame temperature, and method is adulterated to increase excess air
Cold wind is more, causes combustion reaction slack-off.Discounting for extension reaction zone (increasing combustion space), then efficiency of combustion is reduced, in flue gas
Fuel, oxygen are not use up has rise.Set up flue gas Multiple Cycle resume combustion pattern, then can effectively drain in combustion gas it is flammable into
