Technical field
The utility model relates to the some partner who lights iron and steel enterprise's diffusing tower emission coal gas and burns device, refers in particular to a kind of coal gas that diffuses that can directly use and combusts gas and can and accompany direct-fired some partner's burner of burning function integration with igniting as igniting and companion.
Background technology
At present, the high altitude igniter of iron and steel enterprise's diffusing tower all need use the various fuel gas of outer confession, and these outer fuel gas that supply are carried by ad hoc pipeline, are provided with manually-operated gate and by-pass valve control in pipeline loop.Present two parts that comprise commonly used: the one, high altitude igniter is transmitted pipeline and is combined by electric arcing electrode, gas nozzle, air mixing chamber, flame; The 2nd, companion's burner is combined by fuel gas pipeline, combustion head, hurricane globe; Both independent settings, during igniting, external circuit is supplied with the electric arcing electrode high-tension electricity in high altitude igniter, produce electric arc between two arcing electrodes, light the mist of air and combustion gas and jet out flames from the high altitude igniter top, the combustion gas of the companion's burner of igniting combustion head ejection produces larger flame and refires the coal gas that diffusing tower diffuses out.Except these fuel gas need expensive cost, inevitably with under some water and Impurity deposition, cause obstruction in conveyance conduit, make operating cost high maintenance amount large; Especially cold area also needs conveyance conduit is accompanied heat and insulation in the sky, has strengthened operating cost.
Summary of the invention
The purpose of this utility model is for the defective that exists in background technology and problem improvement and bring new ideas in addition, a kind of technique is provided and install simple, igniting and the integrated direct-fired some partner's burner of companion's burner.
The technical solution of the utility model is a kind of direct-fired some partner's burner that is arranged on diffusing tower emission coal gas mouth of structure, comprise opening up poly-flame shell, be arranged on the catalytic reactor in poly-flame shell, be arranged in poly-flame shell the premix chamber that is connected with the catalytic reactor bottom, be arranged on the negative electrode in the premix chamber and be connected to coal gas guide wire, the air delivery tube in premix chamber, and being arranged on the outside and end of poly-flame shell and stretching into arcing electrode in the premix chamber; Wherein coal gas guide wire and air delivery tube carry respectively emission coal gas and air to premix chamber to be mixed and fed into catalytic reactor, the arcing electrode lights that in the premix chamber, mixed gas produces low flame, and in the catalytic reactor that synchronously ignites, mixed gas produces high flame and forms the diffusing tower emission coal gas companion source of making a fire.
Advantage of the present utility model and beneficial effect:
The utility model utilizes guide wire that the coal gas that diffuses is introduced direct-fired some partner's burner, fuel that need not be other, save the fuel gas pipeline, that igniting and companion's burner are formed integrated structural shape, simple in structure being convenient to installed, can directly light blast furnace and coal gas of converter diffusing tower, for iron and steel enterprise's diffusing tower is saved operating cost.
The utility model can directly use the act as a fuel direct-fired high altitude ignition co-burning machine of gas of the coal gas that diffuses, and does not need ad hoc fuel gas pipeline and by-pass valve control, technique and install simple, without the expense of using fuel gas, substantially need not safeguard.
