Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is axial, cross-sectional view of the present invention.
Fig. 2 is side view of the present invention.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See figures.1.and.2, a kind of for the acid-treated gas burner of sulfur waste, comprise: a primary air cyclone 1, one is arranged on main blast tube 2 on primary air cyclone 1 shell and igniter burner 3, and the expansion type burning gallery G that accepts the air sent into by primary air cyclone and the main fuel gas sent into by main blast tube, described expansion type burning gallery side is communicated with burner hearth
Also comprise an ignition module, described ignition module comprises the C interface of the feeding igniting air be arranged on igniter burner, sends into D interface and the K interface inserted for spark lever of igniter fuel gas.
Also comprise the flame detector sleeve pipe being nested with and being arranged on primary air cyclone, described flame detector sleeve pipe is provided with at least three group flame detectors
Wherein in main fuel gas passage 2, front end is furnished with porous form gas spray head M, is divided into multiply to make main fuel gas after shower nozzle.
Be furnished with swirl vane F1 in primary air cyclone 1, make primary air after swirl vane F1, spray into expansion type burning gallery G with certain eddy flow degree; Be furnished with swirl vane F2 in main fuel gas passage 2, to make main fuel gas after swirl vane F2, spray into expansion type burning gallery G with certain eddy flow degree and efficiently mix with primary air.
Igniting air enters igniter burner 3 by C interface, and igniter fuel gas enters igniter burner by D interface, and the spark lever of high-energy igniter inserts from K interface.Two kinds of gas, is lighted by spark lever at igniter burner after burner hearth side leading portion mixes, and forms chief operator's naked light flame.
Primary air enters air cyclone 1 from A interface, and advanced person crosses air channel rectification, then enters expansion type burning gallery G by swirl vane F1.
Main fuel gas enters fuel gas sleeve pipe 2 from B interface, after sleeve channel rectification, then is sprayed from shower nozzle M by swirl vane F2.Main fuel gas and primary air fully mix in expansion type passage, and pass through the bright flame ignition of chief operator of igniter burner 3.
On gas combustion burner device, three flame detectors are installed, the flame detector wherein installed at interface E1 and E2 place is used to the flame detecting main combustion gas generation, installs chief operator's naked light flame that a flame detector produces to detect igniter burner 3 at burner hearth place.
The signal of three flame detectors feedback enters parking locking system, when three flame detectors occur more than two comprise two can't detect the situation of flame time, fuel gas and air door fast shut-off, burner stops in emergency to ensure safety.Fuel gas under different operating mode and the adjustment of air mass flow are realized by the control valve on fuel gas and air duct.
Device height is integrated, saves arrangement space.The igniter of burner, igniter burner and main burner all adopt sleeve structure, are integrated on air cyclone shell together with flame detector, flame visor sleeve pipe.While not affecting service behaviour, save the arrangement space of whole combustion system.
Be applicable to variable concentrations and contain more polymictic Waste Sulfuric Acid thermal decomposition process.In the technique that Waste Sulfuric Acid reclaims, Waste Sulfuric Acid thermal decomposition is a high endothermic reaction.The highest for ensureing the conversion ratio of Waste Sulfuric Acid thermal decomposition, react best and carry out at the temperature of 1000 DEG C, the thermal decomposition of Waste Sulfuric Acid also can be carried out under the temperature below 850 DEG C, but reaction speed is too slow.Therefore need burning high heat value gas to provide Waste Sulfuric Acid is heated to reaction temperature and carries out the heat required for thermal decomposition.Along with Waste Sulfuric Acid recovery process is in the development of the industry such as chemical industry, iron and steel, will process variable concentrations waste sulfuric acid solution, in the waste sulfuric acid solution particularly had, sulfuric acid content is low and impurity is more, required thermal decomposition heat and heat decomposition temperature different, therefore not identical with the demand of air-fuel ratio to the flow of fuel gas.Gas burner can meet the change of 10 ~ 120% operating modes, adjusts than up to more than 1:10, can provide the heat required for Waste Sulfuric Acid thermal decomposition and the reaction temperature of variable concentrations, and when large power condition changing, flame stabilization, flame rigidity is good, and ignition temperature is even.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
