Or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot understand
For the limitation to the invention.In addition, term " first ", " second " etc. are used for description purposes only, and should not be understood as indicating
Or it implies relative importance or implicitly indicates the quantity of indicated technical characteristic." first ", " second " etc. are defined as a result,
Feature can explicitly or implicitly include one or more of the features.In the description of the invention, unless separately
It is described, the meaning of " plurality " is two or more.
In the description of the invention, it should be noted that unless otherwise clearly defined and limited, term " peace

It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
Below with reference to embodiment come the present invention will be described in detail create.
A kind of anticlogging industrial furnace day flare pipe, as shown in Figure 1, including material jet pipe, which includes extremely
A few material channel；The material outside of the nozzle is equipped with water jacket 1, is equipped with heat generating member 2 at material jet pipe spout end；The fever
Refractory material 3 is filled between part and water jacket.Cooling water set is set in outside of the nozzle, spray is protected using the principle of dross
Pipe, it is ensured that the operation steady in a long-term of jet pipe.
As shown in Fig. 2, above-mentioned material jet pipe includes the peripheral tube 4 in central tube 10 and its outside, one is formed in central tube
Center material channel 5 forms several other peripheral material channels 6 in peripheral tube.
Certainly, above-mentioned material jet pipe can also be including central tube and several layers of peripheral tube being sleeved on the outside of central tube, such as
Shown in Fig. 3, a center material channel is formed in central tube, between most inner side peripheral tube and central tube and each peripheral tube
Between to form cross section be cricoid peripheral material channel.It may be constructed peripheral material channel between adjacent peripheral pipe, outside most inner side
Bustle pipe and central tube also collectively form peripheral material channel.When using the case where peripheral tube forms several peripheral material channels
Under, water jacket is sleeved on the outside of outermost peripheral tube.
Above-mentioned heat generating member uses tubular structure, and internal diameter is greater than material jet pipe spout end diameter.In addition, heat generating member can also be with
Using upper and lower corresponding two heat block.In general, above-mentioned heat generating member uses thermo electric material, temperature range is after heating power
1200-1600 DEG C, Re≤1700 DEG C Nai.Lanthanum Chromite, zirconium oxide or molybdenum silicide can be selected in thermo electric material.
Water inlet 7, water outlet 8 are set in the different location of water jacket, by the continuous circulation of cooling water, guaranteed to jet pipe
Water-cooled effect is stablized.
For selecting 36 volts and safe voltage below to the voltage that heat generating member is powered, electrode and thermo electric material are bridged.It is powered
Conducting wire 9 can by water jacket pass through (using water proof type conducting wire or having set up the structures such as water string), be mentioned using cooling jacket
The low temperature environment of confession, to protrude into the power supply of the heat generating member in furnace.It is of course also possible to use other line arrangement modes, for example, logical
Electric lead can be passed through from the vacant peripheral material channel close to water jacket, but in this case, it needs to improve outside conducting wire
The temperature classification of table insulating materials.
It is heat-insulated using being filled with certain thickness refractory material for the gap between heat generating member and water jacket.It needs
It is emphasised that: the refractory material poor thermal conductivity of the filling, i.e. thermal-insulating type refractory material can be indefinite form, can also
Be it is prefabricated, in use, which can be formed together dross protective layer with slag, play heat-insulated and firm electric heating material
The effect of material.
The working principle of heat generating member of the present invention are as follows: the operating current for adjusting thermo electric material is allowed to temperature and is in certain
One temperature makes it higher than the average fusing point of the material of spout addition, the surface of heater is kept to be in " wet " state always,
So, solid glue would not be formed in the exit of spout, jet pipe would not block up.It certainly, is reduction energy consumption, electric heating material
Material does not need to remain powered on state constantly yet, for example opens at a fixed time interval, and nozzle is made not yet to form membranaceous package
Glue fusing.If the spout of spray head seldom will appear stopping state in actual production, which then may be used
As a kind of spare troubleshooting means, be powered enabling again when spout blocking.
It should be pointed out that under certain conditions, it may not be necessary to be powered, but go to heat using the temperature of melt
The heat generating member is also able to achieve " wet " of material surface, and spout is kept not block up.In this case, the range of choice of material is more
It is wide in range.As an example, not a limit, for example, selecting silicon carbide fibre complex silicon carbide.As long as material high temperature resistant has intensity.
The invention structure is simple, and maintenance and operation element amount are few, and use cost is low, efficiently solves jet pipe heat resistance
Problem extends the service life of jet pipe, while also effectively avoiding the clogging that outside nozzle is likely to occur, work
It is reliable and stable.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
