Description
Technical field
The utility model relates to one with stacked bed configuration porous media combustor, is particularly useful for the burning of the low-BTU gas such as coal mine light concentration mash gas, low concentration natural gas, blast furnace gas, and settles the heat exchanger tube of various shape.
Background technology
It is high that multi-hole medium combustion technology has efficiency of combustion, the lean combustion limit is wide, and flame holding is good, and the feature that pollutant emission is low, compare traditional free flame combustion technology, be very suitable for the burning of the low-BTU gas such as coal mine light concentration mash gas, low concentration natural gas, blast furnace gas.
At present, the primary structure of porous media combustor is the burner be made up of foamed ceramics or ceramic honey comb and the burner be made up of stacked bed configuration.Wherein, foamed ceramics and ceramic honey comb are a kind of fixing structures, as long as after processing, its shape is changeless, and this structure porosity is high, and specific area is large, contributes to exchange heat and realizes low heat value gas burning.Stacked bed configuration is a kind of form of discrete type, can meet the demand of various burner shapes and heat exchanger geometry, but its porosity is low, not as good as foamed ceramics or ceramic honey comb structure in heat exchange.
Existing burner is all single setting class (foamed ceramics or ceramic honey comb) burner or the stacked bed configuration burner of discrete type, the former shape is fixedly unfavorable for placing heat exchanger, the latter's porosity is low is unfavorable for exchange heat, becomes the main bugbear faced in engineering reality.
Summary of the invention
Technical problem: the purpose of this utility model overcomes Problems existing in prior art, provide that a kind of structure is simple, porosity is high, specific area is large, contribute to strengthening exchange heat with stacked bed configuration porous media combustor.
Technical scheme: of the present utility model with stacked bed configuration porous media combustor, the gradual change type tube comprise air inlet pipe, being connected with air inlet pipe, the upper end of gradual change type tube is connected with inner core, the outer layer covers of inner core has heat-insulation layer, the internal layer lower area of inner core is filled with anti-backfire perforated plate, the top of anti-backfire perforated plate is provided with setting class porous media, and top or the middle part of setting class porous media are provided with stacking bed medium.
Described inner core is cylinder or square cylinder.
The structure of described stacking bed medium is coccoid, thread or laminar, and material is aluminium oxide, carborundum, cordierite or mullite.
The thickness of described heat-insulation layer is 3 ~ 10cm.
Described inner core is refractory metal type inner core or ceramic mould inner core.
Described setting class porous media is foamed ceramics or ceramic honey comb structure.
Beneficial effect: owing to have employed technique scheme, the utility model overcomes existing setting class burner heat exchanger and installs complicated, the problem that stacked bed configuration burner porosity is lower, and compared with prior art tool has the following advantages:
1. the heat exchanger tube of various shape can be settled stacking bed position in the burner by burner, simple and convenient, simultaneously, the main body section of burner is setting class porous media structure, and porosity is high, and specific area is large, contribute to strengthening exchange heat, realize the Thorough combustion of low-BTU gas;
2. in the bottom of burner, perforated plate has been installed, has been conducive to preventing flame from strile-bacing, improves the security of equipment.

Detailed description of the invention
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
Of the present utility model with stacked bed configuration porous media combustor, form primarily of gradual change type tube 1, heat-insulation layer 2, inner core 3, stacking bed medium 4, setting class porous media 5, perforated plate 6, air inlet pipe 7.Gradual change type tube 1 is in horn-like, and opening upwards is connected in air inlet pipe 7, and the upper end of gradual change type tube 1 is connected with inner core 3, and described inner core 3 is refractory metal type inner core or ceramic mould inner core.The outer layer covers of inner core 3 heat-insulation layer 2, and the thickness of described heat-insulation layer 2 is 3 ~ 10cm; The internal layer lower area of inner core 3 is filled with anti-backfire perforated plate 6, the setting class porous media 5 that the top being positioned at perforated plate 6 is provided with, and described setting class porous media 5 is foamed ceramics or ceramic honey comb structure.The top of setting class porous media 5 or middle part are provided with the stacking bed medium 4 of the materials such as aluminium oxide, carborundum, cordierite or mullite, described inner core 3 structure can be cylinder type structure or square body structure, the structure of described stacking bed medium 4 is bead, flake or thread, and stacking bed medium 4 is positioned at top or the middle part of setting class porous media 5.
Operation principle: coal mine light concentration mash gas, low concentration natural gas, the low-BTU gas such as blast furnace gas are entered by air inlet pipe, perforated plate 6 is entered at the reducing flows by action of gradual change type tube, after gas through perforations plate 6, enter in the combustion chamber of setting class porous media 5 and stacking bed medium 4 composition, then under the guide functions of inner core 3, burner is flowed out, low-BTU gas is lighted a fire by igniter in the outlet of burner, gas takes fire, the flame that burning produces spreads into downwards in combustion chamber, and realize smooth combustion wherein, the heat that burning produces is by the arrangement heat exchanger transfer in stacking bed medium, the flue gas that burning produces derives burner by inner core.
