Abstract
The invention discloses an exhaust flame arrester which comprises a flame arrester body. A filter element is disposed in the flame arrester body and formed by coiling stainless steel bars and is in the shape of a disc. The stainless steel bars include the toot-shaped steel bar and the plate-shaped steel bar. After the steel bars are coiled into the disc shape, the tooth-shaped steel bar and the plate-shaped steel bar are arranged in a spaced mode and are plated with a catalyst plating layer. According to the exhaust flame arrester, a precious metal catalyst layer is plated on the filter element, HC and CO are made to be oxidized to generate steam and carbon dioxide, NOx is made to be reduced into nitrogen and oxygen, tail gas is purified, and environment pollution is reduced.
Description
Technical field
The present invention relates to Coal Transportation tail gas processing technology field, particularly relate to one and there is cleaning of off-gas function and quick-replaceable exhaust flame trap.
Background technique
Explosion-proof rubber wheel transportation vehicle is the main assistant conveyance vehicle of underground coal mine, and due to subsurface environment requirement, explosion-proof rubber wheel transportation vehicle needs to possess back-fire relief function, and at present, the exhaust flame trap be used on explosion-proof rubber wheel transportation vehicle also only has back-fire relief function.But, containing a large amount of pollutant in the tail gas of vehicular discharge, comprise HC (hydrocarbon), CO (carbon monoxide) and NOx (oxyhydroxide) three kinds of major pollutants matter, space, down-hole is less, the tail gas of discharge cannot spread, larger to human injury.
Summary of the invention
For the deficiency of above-mentioned background technology, one is the object of the present invention is to provide to have cleaning of off-gas function and quick-replaceable exhaust flame trap.
To achieve these goals, exhaust flame trap provided by the invention, comprises flame arrester body, it is characterized in that, flame arrester body inside 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; Profile of tooth steel bar and plate shape steel bar plate outward and are provided with catalyzer coating.
In some embodiments, catalyzer coating is the precious metal plating with oxidation and restoring function.
In some embodiments, flame arrester body also comprises the flange plate being located at filter core both sides, and flange plate corner place is connected by bolt and nut, is also provided with multiple guide rod between two flange plate, guide rod is provided with Compress Spring, and Compress Spring two ends are to being located at inside two flange plate.
The present invention compared with prior art, has the following advantages:
One, exhaust flame trap provided by the invention, filter core establishes precious metal catalyst layer by plating, impels HC and CO to be oxidized sky producing water vapor and carbon dioxide, impels NOx to be reduced to nitrogen and oxygen, cleaning of off-gas, reduce environmental pollution.
Two, exhaust flame trap provided by the invention, adopt two ends compressing structures, 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 flame trap of one embodiment of the present invention.
Fig. 2 is the filter core part structure for amplifying schematic diagram shown in Fig. 1.
Fig. 3 is the structural representation of flame arrester body in the exhaust flame trap of one embodiment of the present invention.
Embodiment
Explanation that the present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Fig. 1 to Fig. 3 schematically shows the exhaust flame trap according to one embodiment of the present invention.
As shown in Figure 3, exhaust flame trap provided by the invention comprises flame arrester body 1, flame arrester body 1 comprises filter core 2 and is located at the flange of filter core 2 both sides (3,4), flange plate (3,4) corner place is connected by bolt 5 and nut 6, two flange plate are also provided with multiple guide rod 7 between (3,4), and guide rod 7 is provided with Compress Spring 8, Compress Spring 8 two ends are to being 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 alternate setting of plate shape steel bar 22.
Profile of tooth steel bar 21 and the outer plating of plate shape steel bar 22 are provided with catalyzer coating, and catalyzer coating is the precious metal plating with oxidation and restoring function, as the precious metal such as platinum, rhodium composition.Platinum catalyst can impel HC and CO to be oxidized sky producing water vapor and carbon dioxide; Rhodium catalyst can impel NOx to be reduced to nitrogen and oxygen.
In sum, exhaust flame trap provided by the invention, filter core has cleaning of off-gas, reduces the function of environmental pollution.
