Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.In addition, if below in described each embodiment of the present invention involved technical characteristic do not form conflict each other and just can mutually combine.
The First air note oxygen conglomerate integration device burned for rubbish oxygen enrichment constructed by the embodiment of the present invention, as shown in Figure 1, arrow is airflow direction, and in figure, namely 2,8 be the adpting flange of this device and First air pipeline, is convenient to the installation and removal of this device.After this device is arranged on First air blower fan, First air hot-air enters 1 by device import, oxygen inlet 3 enters, oxygen filling container comprise be arranged at body 10 body in note oxygen ring 4 in the form of a ring, and the multiple nozzles 5 be evenly arranged on this note oxygen ring 4, oxygen is entered this note oxygen ring 4 and is sprayed into by said nozzle 5 in the body of body 10 from outside.Spray into note oxygen Duan Zhongyu First air hot-air by the nozzle 5 on note oxygen ring 4 tentatively to mix, nozzle is provided with side spray orifice 12 and end spray orifice 13, ensure that nozzle can parallel and vertical both direction injection oxygen, guarantee the preliminary mixing of oxygen and First air air, the oxygen-enriched air of preliminary mixing is mixed further by two groups of Special-shaped sheets, ensure that pure oxygen can fully be diffused in First air air, in figure, the direction of arrow is airflow direction, Special-shaped sheet group mainly plays perturbation action, impels pure oxygen to mix with air.A unit Special-shaped sheet group is made up of Special-shaped sheet 6 and Special-shaped sheet 7, the gas channel of Special-shaped sheet 6 is positioned at the external margin of disk, the gas channel of Special-shaped sheet 7 is then positioned at disk inside, the gas channel of Special-shaped sheet 6 is kind elliptical shapes as seen from Figure 4, formed by the cutting of two circular arcs with radius, radian is 60-90 °; The gas channel of Special-shaped sheet 7 is then inner concentric circles, and radius is 1/3-1/2 of Special-shaped sheet.When air-flow is by Special-shaped sheet, due to the existence of this structure of Special-shaped sheet, its barrier effect can produce the backflow of local, backflow can strengthen the disturbance between gas, the diffusion of molecule is impelled to mix, the difference of Special-shaped sheet gas channel is arranged and is more facilitated this melange effect, ensure that the air-flow mixed effect under different pressures, flow.Well-mixed oxygen-enriched air then enters incinerator burning zone by outlet 9, participates in burning.
Note oxygen ring shown in Fig. 2 arranges oxygen jet uniformly, preferably every 20-45 ° of nozzles, determined by the oxygen supply demand of concrete unit.Note oxygen side adpting flange 11 is for connecting oxygen main.The material of note oxygen ring and adpting flange adopts stainless steel or copper, to guarantee that oxygen channel and note oxygen mix oxygen equipment safety.In Fig. 3, the top of nozzle and sidewall are furnished with spray orifice, and the spray orifice 12 of sidewall is preferably respectively towards 4 different directions, and such as 3, each direction, totally 12 spray orifices, add a spray orifice on top, each nozzle preferably has 13 spray orifices.The material of nozzle should adopt copper, guarantees safety.
Fig. 4 is the schematic diagram of mixed flow sheet group (i.e. Special-shaped sheet group), and each mixed flow sheet group comprises mixed flow sheet 6 and mixed flow sheet 7 two round sheet parts.Wherein the gas channel of mixed flow sheet 6 (also referred to as Special-shaped sheet) is class elliptical shape, is formed by the cutting of two circular arcs with radius.The gas channel of another kind of Special-shaped sheet (i.e. mixed flow sheet 7) is then the concentric circles of inside, and radius is 1/3-1/2 of Special-shaped sheet, and the Special-shaped sheet group of two unit plays perturbation action, impels mixing of oxygen and air,
In this device, the quantity of special-shaped unit group can be determined by unit size, and such as the present embodiment is preferably applied to the incinerator of 350t/d, and its note oxygen amount is 0-1500m
3/ h (standard state), only need arrange 2 groups of Special-shaped sheets, if be applied to more jumbo incinerator can suitably increase 1-2 group, but can not be too many, too many Special-shaped sheet group can cause pipeline local resistance comparatively large, if blower fan is exerted oneself not, can affect the operation of unit.Special-shaped sheet group should adopt stainless steel, prevents corrosion.Because First air temperature is generally 150-200 DEG C, the operating temperature ratings of package unit should preferably at about 200 DEG C, and material should use stainless steel.
In device of the present invention, its note oxygen section and the integration of mixed oxygen section, internal-injection type ring-type oxygen filling container is adopted in note oxygen section, oxygen filling container is uniformly distributed nozzle (every 20-45 ° of nozzles), nozzle is furnished with top and sidewall two class spray orifice, ensure that oxygen can spray into from horizontal and vertical First air airflow direction, oxygen is fully diffused in hot-air; The special-shaped unit of difformity Special-shaped sheet composition is furnished with in mixed oxygen section, a kind of gas channel of Special-shaped sheet is class elliptical shape, formed by the cutting of two circular arcs with radius, the gas channel of another kind of Special-shaped sheet is then inner concentric circles, and radius is 1/3-1/2 of Special-shaped sheet, and the Special-shaped sheet group of two unit plays perturbation action, impel mixing of oxygen and air, even if less in oxygen spray amount, when eject momentum is lower, also can ensure fully mixing of oxygen and air.Mounting flange arranged by package unit, can be directly installed on existing First air pipeline, without the need to changing pipeline.
On the First air pipeline that apparatus of the present invention can be widely used in all kinds of incinerator, oxygen and air mixes, if and relate to injection mixing (the air in pipeline stable chemical nature of oxygen in relatively large pipeline, can not oxygen react) time, all can apply this device.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
