Abstract
An oxygen-enriched combustor comprises an outer layer protective shell, a combustion-supporting medium cavity, a combustion gas cavity and a combustor port. The combustion-supporting medium cavity is arranged inside the outer layer protective shell and communicated with the combustor port, the combustion gas cavity is communicated with the combustor port through a combustion gas tube and arranged inside the outer layer protective shell which is corresponding to the combustor port, the outer circumference of the combustion gas tube is provided with helical guide plates, and guide channels are formed between adjacent helical guide plates. The outer layer protective shell is provided with a cooling medium cavity filled with cooling media. When materials are calcined in industrial furnaces, industrial gases are injected into the combustion gas cavity and transported to the combustor port through the combustion gas tube, oxygen-enriched combustion-supporting media are injected into the combustion-supporting medium cavity and form rotating airflows through the helical guide channels to be transported to the combustor port, the industrial gases and the oxygen-enriched combustion-supporting media formed the rotating airflows are mixed fully at the combustor port and then combusted so as to increase the combustion temperature, thereby reducing the exhaust gases yields in the combustion process and thermal loss of unit product.
Description
Technical field
The utility model relates to a kind of combustion apparatus, particularly a kind of oxygen-enriched burner that is used for industrial furnace.
Background technology
At present, existing and once had about mechanical engineering, illumination, heating, weapon, explosion portion, combustion apparatus, combustion method class, the combustion apparatus technology was all done effectively effort to the demand of burner in the stove, also once designed many outstanding technical schemes, as declaring of the Decree of Patent Office of China in 2007 by Te Luzi. Fu Kasi responsibility Co., Ltd, Granted publication number is CN1795251, patent is: No. 200610150462.7 patent of invention title is the patent of invention of " burning beam that is used for kiln for lump material ", the technical scheme that is adopted.Mechanical engineering, illumination, heating, weapon, explosion portion, combustion apparatus, combustion method class, the combustion apparatus technical elements is a routine of great value invention, it has effectively solved the even calcining technology problem of lump material.But still have some deficits, it is low that it also is difficult to solve the flame temperature of low heat value industrial gas in combustion process, and it is big to generate exhausted air quantity, the technical problem that the unit product hear rate is high.
The utility model content
The purpose of this utility model provides a kind of raising ignition temperature, reduces stove waste gas growing amount in the combustion process, a kind of oxygen-enriched burner that the unit product hear rate is low.
For achieving the above object; the technical scheme that the utility model adopted is a kind of oxygen-enriched burner; comprise outer layer protection shell, combustion-supporting medium chamber, combustion gas chamber and port; described combustion-supporting medium chamber is positioned at the outer layer protection shell and communicates with port; described combustion gas chamber communicate with port by Gas Pipe and be arranged at the corresponding outer layer protection shell of port in; the excircle of Gas Pipe is provided with spiral helicine deflector, forms flow-guiding channel between the adjacent deflector.
Described outer layer protection shell is provided with the cooling dielectric cavity that the cooling medium is filled.
The beneficial effects of the utility model are: owing to adopted the Gas Pipe that is provided with deflector and flow-guiding channel, the low heat value industrial gas fully mixes at the port place with the oxygen-enriched combustion-supporting agent, carry out oxygen-enriched combusting, the temperature of burning is improved, reduce stove waste gas growing amount in the combustion process, the unit product hear rate reduces.
Description of drawings

Fig. 2 is the enlarged diagram of Gas Pipe outer wall among Fig. 1.
Among the figure, 1, the outer layer protection shell, 2, the combustion gas chamber, 3, the cooling dielectric cavity, 4, port, 5, the combustion-supporting medium chamber, 6, Gas Pipe, 7, deflector, 8, flow-guiding channel.
The specific embodiment
The utility model is a kind of oxygen-enriched burner, it mainly fully mixes industrial gas and oxygen-enriched combustion-supporting agent and carries out oxygen-enriched combusting by mixing guiding gutter, improve stove waste gas growing amount in the ignition temperature reduction combustion process, the purpose that the unit product hear rate reduces to reach.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1; a kind of oxygen-enriched burner; comprise outer layer protection shell 1; combustion-supporting medium chamber 5; combustion gas chamber 2 and port 4; outer layer protection shell 1 adopts the heat-resisting alloy steel processing and manufacturing to become T type structure; laterally run through and be installed in the industrial furnace; outer layer protection shell 1 is provided with cooling dielectric cavity 3; be filled with the cooling medium in the dielectric cavity 3 in cooling and be used for cooling protection outer layer protection shell 1; respectively be provided with a plurality of ports 4 in the both sides of outer containment vessel 1; combustion gas chamber 2 communicate with port 4 by Gas Pipe 6 and be arranged at port 4 corresponding outer layer protection shells 1 in; combustion-supporting medium chamber 5 is positioned at outer layer protection shell 1 and communicates with port 6; the outer wall of Gas Pipe 6 is provided with helical form and twines affixed deflector 7, forms flow-guiding channel 8 between the adjacent deflector 7.
Operation principle of the present utility model is: when industrial furnace to stove in material when calcining, industrial gas injects in the combustion gas chamber 2 and by Gas Pipe 6 and is transported to port 4 places, the flow-guiding channel 8 formation swirling eddies that the oxygen-enriched combustion-supporting medium injects process helical duct shape in the combustion-supporting medium chamber 5 are transported to port 4 places, industrial gas fully mixes with the oxygen-enriched combustion-supporting medium that forms swirling eddy at port 4 places, after the ignition, the flame burning temperature improves, strengthened the penetration power of flame, reduce the oxynitrides growing amount in the combustion process, total stove waste gas growing amount reduces, it is few that waste gas is taken heat out of, the unit product hear rate is low, improve the volumetric efficiency of stove, increased production capacity.
