Description
Technical field
The utility model relates to agglomerating plant, relates in particular to the ignition furnace burner that can prevent pipe backfire.
Background technology
Igniting is important link in the sintering process flow process.In modern sintering process process, ignition furnace is used to provide hot strip flame to mix surface, make solid fuel wherein fire burns, and make top layer compound sintering under ignition furnace high-temperature flue gas and solid fuel ignition exothermic effects, the heat that provides sufficient oxygen amount that the top layer is put aside by the air exhauster exhausting is passed to down one deck compound simultaneously, makes sintering process carry out rapidly downwards thereby impel the solid fuel that descends one deck to burn away.Ignition furnace on the market generally is energy medium with coal gas at present, coal gas then is divided into three kinds of coke-stove gas, blast furnace gas and burnt high mixed gases, different calorifics value of gas is different, needed empty coal has nothing in common with each other than also during burning, and empty coal than the size ordering is: coke-stove gas＞mixed gas＞blast furnace gas.Coal gas is connected by pipeline with air and enters into burner inside, and in the inner share split of burner, mixing produces thermal-flame in the combustion of burner stomion then.When the daily production of ignition furnace, because all extraneous factors, the situation that the pressure of combustion-supporting coal gas before the burner or combustion air suddenly reduces appears sometimes.In this case, if the site operation personnel does not in time make a response, then very likely cause just entering lower air or the gas piping of pressure that links to each other with burner before the burner, thereby cause a series of serious accidents such as pipe explosion, coal gas leak in the burned flame tempering.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of ignition furnace burner that can effectively prevent tempering phenomenon in the ordinary production, raising safety coefficient, guarantee operator safety, improve prevented from the pipe backfire of ignition furnace operating efficiency is provided.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of ignition furnace burner that prevents pipe backfire comprises burner body, and described burner body is provided with the burning gases mouthpiece, is equiped with the check-valves that prevents gas backstreaming on the described burning gases mouthpiece.
Described check-valves comprises valve plate, seal locating part and be the valve body of square tube shape, and described valve plate one side is articulated in the valve body, and described sealing locating part is fixed in the valve body, when described valve plate upwards turn to and contacts with described sealing locating part with the valve body complete closed.
Described check-valves also comprises the gap locating part, and described gap locating part is fixed on valve plate or the valve body, described valve plate turn to downwards described gap locating part when being supported between valve plate and the valve body valve body open fully.
Described valve body vertically arranges and is provided with flange in two ends up and down in valve body, and described valve body is tightly connected by flange and bolt fastener and burning gases mouthpiece.
Described burning gases mouthpiece comprises coal gas mouthpiece and air interface pipe.
Compared with prior art, advantage of the present utility model is:
The ignition furnace burner of pipe backfire that prevents of the present utility model is equiped with the check-valves that prevents gas backstreaming on the burning gases mouthpiece, when the ignition furnace ordinary production, if the situation that pressure falls suddenly occurs in certain burning gases mouthpiece, flame will return in the burner pipeline lower toward pressure and scurry, this moment, check-valves will cut out the very first time, prevent that the interior gas backstreaming of burner is in the combustion-supporting gas mouthpiece, be limited in burner inside with returning the flame of scurrying, thereby breaking off source of the gas simultaneously extinguishes it, avoided flame to return and scurried to trunk line, explosion caused accident can effectively prevent tempering phenomenon in the ordinary production, improve safety coefficient, ensure operator safety, improve the ignition furnace operating efficiency.Check-valves in the utility model is made of valve plate, the valve body that seals locating part and be the square tube shape, it is simple and practical, be convenient to fabrication and installation, valve plate upwards turn to when sealing locating part and contact the valve body complete closed, can avoid the valve plate upset excessively and cause sealing to lose efficacy.Valve plate turn to valve body downwards when opening fully, and the gap locating part is supported between valve plate and the valve body, makes between valve plate and the valve body to keep certain interval, forms the higher-pressure region when making gas backstreaming in this gap, thereby with valve plate jack-up, automatic-closing valve.When tempering stops, pressure reduce after valve plate can be returned to the position of opening fully under the effect at self gravitation again, continue ordinary production.
