Embodiment
Below by specific embodiment the utility model is further specified.
As depicted in figs. 1 and 2, this splitting decomposition electric furnace special for ultraluminescence sulphur determination device from inside to outside comprises burner hearth, heat-insulation layer 2 and as the air-cooled wall 1 of shell, described burner hearth is made up of combustion chamber 4 and combustion chamber overcoat 3 successively.As shown in Figure 3, described combustion chamber 3 outside surfaces have helical groove, twine electric furnace heating wire 5 in the described helical groove.As depicted in figs. 1 and 2, air-cooled wall 1 has wind path ring cavity 9, and as shown in Figure 4, the outer wall of this air-cooled wall 1 has 4 the tunnel and is the notch 8 that all shapes of ring are arranged.As shown in Figure 1, air-cooled wall 1 is outside equipped with electric connection 6, and described electric furnace heating wire 5 connects electric connection 6, and electric connection 6 is a porcelain connector.Have thermometric jack 7 on the described air-cooled wall 1, lay the thermopair that obtains temperature signal in this thermometric jack 7.
In conjunction with Fig. 1～4, further specify as follows:
Combustion chamber overcoat 3 is a thick cylinder, and long 340mm opens the notch of a wide 8mm along its length, to make things convenient for combustion chamber 4 to insert and the derivation of electric furnace heating wire 5 two ends.
