Above-mentioned and/or additional aspect of the present utility model and advantage are from obviously and easily understanding becoming the description of embodiment in conjunction with following accompanying drawing, wherein:
Fig. 1 is the structural representation according to the non-immersed top-blown spray gun of the utility model embodiment;
Fig. 2 is the partial enlarged view of A part among Fig. 1.
The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the utility model, and can not be interpreted as restriction of the present utility model.
Top-blown spray gun with the reduction oxidation furnace that is used for refining phosphorus by hot method is that example is described embodiment of the present utility model below, for example, non-immersed top-blown spray gun sprays natural gas or oxygen, passes through annular gas chamber injection of oxygen by central tube in reduction oxidation furnace, and uses water cooling.But it will be appreciated that, be not limited to such use according to non-immersed top-blown spray gun of the present utility model.
As illustrated in fig. 1 and 2, the central tube 1, intermediate casing 2, outer layer sleeve 3, the isolated tube 4 that comprise the forming sleeves structure according to the non-immersed top-blown spray gun of the utility model embodiment.
The centre bore 11 of central tube 1 is used for spraying into fuel, for example natural gas in reduction oxidation furnace.Need to prove, for refining phosphorus by hot method, at holding stage, the centre bore 11 of central tube 1 sprays into fuel in reduction oxidation furnace, but in the blowing stage, the centre bore 11 of central tube 1 does not spray into fuel in reduction oxidation furnace, alternatively, the centre bore 11 of central tube 1 can with below with annular gas chamber 5 the same oxygen-containing gas, for example air or oxygens of describing of in reduction oxidation furnace, spraying into.
As illustrated in fig. 1 and 2, in one example, fuel nozzle 10 is installed, so that the injection of fuel in reduction oxidation furnace and the burning of fuel in the lower end of central tube 1.
Intermediate sleeve pipe box 2 on central tube 1, thereby between intermediate casing 2 and central tube 1, form annular gas chamber 5, be used in reduction oxidation furnace, spraying into oxygen-containing gas, for example oxygen or air.
In one example, convergent-divergent channel 8 is installed,, makes in the easier melt of sending in the reduction oxidation furnace of oxygen, improve the melting effect to increase the jet velocity and the pressure of oxygen in the lower end of intermediate casing 2.
Isolated tube 4 is inserted into indoor interior annular cooling water chamber 6 and the exterior annular cooling water chamber 7 that communicates with each other that be isolated into the annular cooling water chamber of annular cooling water.In one example, the cooling water of supplying with from cooling water source enters in the interior annular cooling water chamber 6, through after the heat exchange, enter exterior annular cooling water chamber 7 from the lower end, thereby cooling water non-interference before and after the heat exchange and the cooling water travel path in spray gun prolongs, thereby has improved cooling effect.
As shown in Figure 1, in an example of the present utility model, non-immersed top-blown spray gun further comprises fuel inlet pipe 12, oxygen-containing gas inlet tube 13, oral siphon 14 and outlet pipe 15.
