Description
Technical field
The utility model relates to a kind of neat gas burner, is specifically related to a kind of carbon anode roasting furnace neat gas burner.
Background technology
At present, the normal open roasting furnace that adopts produces aluminium cathode material, and wherein the key link is that roasting technique controls.Nowadays, natural gas replaces heavy oil to become a kind of trend, and in actual production, the malcombustion of natural gas can cause non-uniform temperature in quirk, and the quirk temperature difference is comparatively large, affects greatly roaster service life, baked anode quality.According to burning of gas feature, burner outlet flow velocity size, can directly affect the temperature difference in spray penetration, flame intensity and quirk.Meanwhile, in combustion of natural gas process, as air excess, exhaust gas volumn increases, and takes away partial heat, causes fire path temperature to reduce, and the thermal efficiency reduces; Lack of air, burns insufficient, causes waste of fuel.And existing burner nozzle is all integral nozzle, because burner uses for a long time under high-temperature oxidation environment, causes burner nozzle to be deposited and be easily subject to oxide etch, and need often more nozzle, cause use cost higher.
Utility model content
The purpose of this utility model is, provide a kind of carbon anode roasting furnace neat gas burner that can improve combustion of natural gas state, make jet flames long, long service life, easy to operate, use cost is low, to overcome deficiency of the prior art.
The technical solution of the utility model: a kind of carbon anode roasting furnace neat gas burner, comprise the burner lid be connected with roaster, the external side of burner lid is threaded with gas mixing tube, burner lid medial extremity is threaded with burner noz(zle), gas mixing tube is communicated with burner noz(zle), described gas mixing tube lower end be circumferentially provided with airport, gas mixing tube upper end is connected with the threaded one end of tube connector, the tube connector other end is connected with natural gas tube, natural gas nozzle one end is threaded with the round platform in gas mixing tube, the other end extends in burner noz(zle), the gap that natural gas outer nozzle wall and gas and vapor permeation inside pipe wall are formed is greater than the gap that natural gas outer nozzle wall and burner noz(zle) inwall are formed,
Described burner lid offers quirk peep hole;
Described gas mixing tube is provided with the adjustable cap regulating airport air inflow;
Described burner noz(zle) is made up of burner noz(zle) top and burner noz(zle) bottom, and described burner noz(zle) top is connected with burner noz(zle) lower thread;
Described natural gas nozzle is become with natural gas nozzle lower set by natural gas nozzle top, and described natural gas nozzle top is connected with natural gas nozzle lower thread, and the internal diameter on natural gas nozzle top is greater than natural gas nozzle lower inner diameter.
Owing to have employed technique scheme, the utility model has the advantage of: the gap that in the utility model, natural gas outer nozzle wall and gas and vapor permeation inside pipe wall are formed is greater than the gap that natural gas outer nozzle wall and burner noz(zle) inwall are formed, therefore, when natural gas sprays from burner noz(zle), just negative pressure can be produced in gas mixing tube and burner noz(zle), air is inhaled in gas mixing tube and natural gas nozzle because of negative pressure, the air capacity be inhaled into can be realized by the area (being equivalent to change the pore size of airport) regulating adjustable cap to cover airport, for combustion of natural gas provides rational air capacity, make combustion of natural gas in good condition.In addition, the utility model is by extending the length of natural gas nozzle and burner noz(zle), natural gas is not only made to burn in quirk depths, control the temperature difference in quirk, make homogeneous temperature in quirk, and air enter gas mixing tube after can be subject to preheating, therefore can improve the initial temperature of gas after mixing with natural gas, improve combustion efficiency; Meanwhile, entering of air also can play certain cooling-down effect to natural gas nozzle and burner noz(zle), extends its service life.And the utility model burner noz(zle) and natural gas nozzle are all made into split-type structural, its upper and lower two parts are threaded connection, therefore, after burner noz(zle) or natural gas nozzle bottom are due to long-time high temperature oxidation and corrosion, can be for convenience detach, and change new working on, and without the need to changing whole burner noz(zle) or natural gas nozzle, reduce use cost.

Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
See Fig. 1, a kind of carbon anode roasting furnace neat gas burner of the present utility model, comprises the burner lid 11 be connected with roaster, and described burner lid 11 offers quirk peep hole 6, burner lid 11 outboard end is threaded with gas mixing tube 3, burner lid 11 medial extremity is threaded with burner noz(zle), gas mixing tube 3 is communicated with burner noz(zle), described gas mixing tube 3 lower end be circumferentially provided with airport 5, gas mixing tube 3 upper end is connected with the threaded one end of tube connector 2, tube connector 2 other end is connected with natural gas tube 1, natural gas nozzle top 7 is threaded with the round platform in gas mixing tube 3, natural gas nozzle bottom 8 extends in burner noz(zle), described natural gas nozzle top 7 is threaded with natural gas nozzle bottom 8, therefore, when natural gas jets bottom 8 is subject to oxide etch, be convenient to change.The internal diameter on natural gas nozzle top 7 is greater than natural gas nozzle bottom 8 internal diameter, and natural gas nozzle lower tube footpath diminishes, and plays pressurization, therefore, combustion flame can be made to spray into quirk depths to the natural gas of ejection, ensures that fire path temperature is even.The gap that the outer wall on natural gas nozzle top 7 and gas mixing tube 3 inwall are formed is greater than the gap that the outer wall of natural gas nozzle bottom 8 and burner noz(zle) top 9 inwall are formed, and described burner noz(zle) top 9 is threaded with burner noz(zle) bottom 10.Described gas mixing tube 3 is provided with the adjustable cap 4 regulating airport 5 air inflow, the air capacity be inhaled in burner noz(zle) can be equivalent to change airport pore size by the area regulating adjustable cap 4 to cover airport 5 realizes, for combustion of natural gas provides rational air capacity, make combustion of natural gas in good condition.
