Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, provides a kind of burner adding air preheat pipeline.
The technical scheme in the invention for solving the technical problem is: a kind of energy-saving tundish burner, is characterized in that: comprise combustion tube, CO air inlet pipe, air intake duct and economizer bank; The upper end of described combustion tube is provided with an air inlet, and one end of described CO air inlet pipe is inserted in the inner chamber of combustion tube through the air inlet of combustion tube upper end; Be provided with a blender in the inner chamber of described combustion tube, described blender is provided with inner air flue, and the cavity of burner is divided into upper and lower two chambeies by described blender, and described upper plenum is gas mixer chamber; Described economizer bank is annular, and described combustion tube is connected with economizer bank through the centre bore of economizer bank; Described economizer bank is respectively equipped with air inlet and gas outlet, the air inlet of described economizer bank is connected with one end of air intake duct; The sidewall of the gas mixer chamber of described combustion tube is provided with an air inlet, and the gas outlet of described economizer bank is connected with the air inlet on combustion tube sidewall by tube connector; A baffle plate is provided with in described economizer bank.
The diapire of the inner chamber of above-mentioned economizer bank is provided with multiple heating plate.
Hinged with multiple wind wheel in the inner chamber of above-mentioned economizer bank.
Compared with prior art, the utility model has following outstanding beneficial effect:
1, the utility model has set up economizer bank, utilizes the physical thermal of the high-temperature flue gas of discharge to carry out preheating to combustion air, substantially increases the effect of CO gas combustion;
2, in economizer bank of the present utility model, multiple wind wheel is installed, when air enters economizer bank by air intake duct, air driven wind wheel rotates, and wind wheel is in rotation process, again can current downflow in agitation air, make the air heats in economizer bank even.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the structural representation of blender part in the utility model.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1,2 and 3, the utility model comprises combustion tube 1, CO air inlet pipe 3, air intake duct 5 and economizer bank 2.
The upper end of described combustion tube 1 is provided with an air inlet, and one end of described CO air inlet pipe 3 is inserted in the inner chamber of combustion tube 1 through the air inlet of combustion tube 1 upper end, and the other end of CO air inlet pipe 3 is in order to be connected with CO steam line.Be provided with a blender 8 in the inner chamber of described combustion tube 1, described blender 8 is provided with inner air flue, and as shown in Figure 3, described inside air flue can be multiple through hole.The cavity of burner is divided into upper and lower two chambeies by described blender 8, and described upper plenum is gas mixer chamber.
Described economizer bank 2 is annular, and described combustion tube 1 is connected with economizer bank 2 through the centre bore of economizer bank 2.Described economizer bank 2 is respectively equipped with air inlet and gas outlet, and the air inlet of described economizer bank 2 is connected with one end of air intake duct 5, and the other end of described air intake duct 5 is in order to be connected with the escape pipe of air blast.The sidewall of the gas mixer chamber of described combustion tube 1 is provided with an air inlet, and the gas outlet of described economizer bank 2 is connected with the air inlet on combustion tube 1 sidewall by tube connector 4.
Be provided with a baffle plate 9 in described economizer bank 2, the air inlet on economizer bank 2 and gas outlet separate by described baffle plate 9, and such air can only enter in combustion tube 1 after economizer bank 2 flows a circle again, enables air fully carry out preheating.
The diapire of the inner chamber of described economizer bank 2 is provided with multiple heating plate 7, and described heating plate 7 can increase the area of economizer bank 2 and air heat exchange.
Hinged with multiple wind wheel 6 in the inner chamber of described economizer bank 2, when air enters economizer bank 2 cavity by air intake duct 5, air driven wind wheel 6 rotates, and wind wheel 6 is in rotation process, again can current downflow in agitation air, make the air heats in economizer bank 2 even.
Operating process is as follows: when using the utility model, be arranged on by this device on converter, pass into CO and air respectively, then ignition combustion device by CO air inlet pipe 3 and air intake duct 5.In burner combustion process, produce a large amount of flue gases and heat, the flue gas produced and reflect heat are on the wall of the lower end of economizer bank 2, economizer bank 2 is heated, at this moment gas in economizer bank 2 is passed into and economizer bank 2 carries out heat exchange, thus preheating is carried out to the air entered in combustion tube 1, when air enters economizer bank 2 by air intake duct 5, air driven wind wheel 6 rotates, wind wheel 6 is in rotation process, again can current downflow in agitation air, make the air heats in economizer bank 2 even.
It should be noted that; particular of the present utility model has been described in detail the utility model; for a person skilled in the art, the various apparent change carried out it when not deviating from spirit and scope of the present utility model is all within protection domain of the present utility model.
