Abstract
The utility model discloses exhaust catalysis flame trap, comprise flame trap body, flame trap body interior is provided with filter core, and filter core is that stainless steel steel bar is coiled to form, in the form of annular discs; Stainless steel steel bar comprises profile of tooth steel bar and plate shape steel bar, be coiled into discoid after, profile of tooth steel bar and the alternate setting of plate shape steel bar; The outer plating of profile of tooth steel bar and plate shape steel bar is provided with catalyzer coating.The exhaust catalysis flame trap that the utility model provides, filter core is established precious metal catalyst layer by plating, impels HC and CO to be oxidized born water vapor and carbon dioxide, impels NOx to be reduced to nitrogen and oxygen, and cleaning of off-gas reduces environmental pollution.
Description
Technical field
The utility model relates to Coal Transportation tail gas processing technology field, relates in particular to a kind of have cleaning of off-gas function and quick-replaceable exhaust catalysis flame trap.
Background technique
Explosion-proof rubber wheel transportation vehicle is the main assistant conveyance vehicle under coal mine, and due to subsurface environment requirement, explosion-proof rubber wheel transportation vehicle need to possess back-fire relief function, and at present, the exhaust catalysis flame trap being used on explosion-proof rubber wheel transportation vehicle also only has back-fire relief function.But, in the tail gas of vehicular discharge, contain a large amount of pollutants, comprise HC (hydrocarbon), CO (carbon monoxide) and three kinds of major pollutants matter of NOx (oxyhydroxide), space, down-hole is less, the tail gas of discharge cannot spread, larger to human injury.
Model utility content
For the deficiency of above-mentioned background technology, the purpose of this utility model is to provide a kind of have cleaning of off-gas function and quick-replaceable exhaust catalysis flame trap.
To achieve these goals, the exhaust catalysis flame trap that the utility model provides, comprises flame trap body, it is characterized in that, flame trap body interior is provided with filter core, and filter core is that stainless steel steel bar is coiled to form, in the form of annular discs; Stainless steel steel bar comprises profile of tooth steel bar and plate shape steel bar, be coiled into discoid after, profile of tooth steel bar and the alternate setting of plate shape steel bar; The outer plating of profile of tooth steel bar and plate shape steel bar is provided with catalyzer coating.
In some embodiments, catalyzer coating is the precious metal plating with oxidation and restoring function.
In some embodiments, flame trap body also comprises the flange plate of being located at filter core both sides, and four jiaos of places of flange plate connect by bolt and nut, are also provided with a plurality of guide rods between two flange plate, guide rod is provided with Compress Spring, and Compress Spring two ends are supported and are located at two flange plate inner sides.
The utility model compared with prior art, has the following advantages:
One, the exhaust catalysis flame trap that the utility model provides, filter core is established precious metal catalyst layer by plating, impels HC and CO to be oxidized born water vapor and carbon dioxide, impels NOx to be reduced to nitrogen and oxygen, and cleaning of off-gas reduces environmental pollution.
Two, the exhaust catalysis flame trap that the utility model provides, adopts two ends compressing structure, and filter core is located between the compressing structure of two ends, only need unclamp compressing structure, just can directly take out, and installation, convenient disassembly are quick.
Accompanying drawing explanation
Fig. 1 is the structural representation of filter core in the exhaust catalysis flame trap of a kind of mode of execution of the utility model.
Fig. 2 is the filter core part structure for amplifying schematic diagram shown in Fig. 1.
Fig. 3 is the structural representation of flame trap body in the exhaust catalysis flame trap of a kind of mode of execution of the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail to explanation.
Fig. 1 to Fig. 3 schematically shows the exhaust catalysis flame trap according to a kind of mode of execution of the utility model.
As shown in Figure 3, the exhaust catalysis flame trap that the utility model provides comprises flame trap body 1, flame trap body 1 comprises filter core 2 and is located at the flange (3,4) of filter core 2 both sides, flange plate (3,4) four jiaos of places connect by bolt 5 and nut 6, between two flange plate (3,4), be also provided with a plurality of guide rods 7, guide rod 7 is provided with Compress Spring 8, Compress Spring 8 two ends are supported and are located at two flange plate (3,4) inner side.Filter core 2 is located between flange plate (3,4), and filter core is located between the compressing structure of two ends, only need unclamp compressing structure, just can directly take out, and installation, convenient disassembly are quick.
As depicted in figs. 1 and 2, filter core 2 is coiled to form for stainless steel steel bar, in the form of annular discs; Stainless steel steel bar comprises profile of tooth steel bar 21 and plate shape steel bar 22, be coiled into discoid after, profile of tooth steel bar 21 and the 22 alternate settings of plate shape steel bar.
Profile of tooth steel bar 21 and the 22 outer platings of plate shape steel bar are provided with catalyzer coating, and catalyzer coating is the precious metal plating with oxidation and restoring function, and metal as precious in platinum, rhodium etc. forms.Platinum catalyst can impel HC and CO to be oxidized born water vapor and carbon dioxide; Rhodium catalyst can impel NOx to be reduced to nitrogen and oxygen.
In sum, the exhaust catalysis flame trap that the utility model provides, filter core has cleaning of off-gas, reduces the function of environmental pollution.
