Background technology
At present, tube furnace occupies an important position in the system of processing of some enterprise, also is the major equipment of energy consumption.Tube furnace is controlled the output of different process component in the coal tar distillation process accurately by the control furnace temperature.Restructuring in the coal tar divides bitumen, the heavy dregs composition that contains trace, general viscosity is very high, and in heat-processed, form knot carbon in the boiler tube tube wall easily, affect flow and the heating efficiency of material, when situation is serious, in addition can producer the blockage phenomenon, so coal tar in tube furnace thermally equivalent and not tie carbon very difficult.
And traditional tube furnace is subjected to thermal effect in order to improve, and most finned tubes that adopt to be increasing heating surface area, but this structure is in operational process, forms knot carbon at the heating tube wall easilier, affects flow and the heating efficiency of material, and effect is run counter to desire.
Prior art generally is to recover the boiler tube use properties by the method for regular shut-down cleaning, but not only workload is large for this method, and must stop work in advance during cleaning, and production is had a negative impact.
The utility model content
Technical problem to be solved in the utility model provides a kind of tar gas pipe type furnace, and it effectively avoids boiler tube knot carbon phenomenon, thereby eliminates defective in the above-mentioned background technology.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of tar gas pipe type furnace comprises body of heater, and the bottom of described body of heater is radiation chamber, and top is convection chamber, and the inside of described radiation chamber and convection chamber is interconnected, and the bosom of described radiation chamber is equipped with burner;
Also comprise at least one boiler tube, described boiler tube is light pipe, and stretch into from described radiation chamber, stretched out by described convection chamber, the radiation section that described every boiler tube is positioned at described radiation chamber becomes the spiral raised shape around described burner, and the convection zone that described boiler tube is positioned at described convection chamber is the Zigzag type shape of level.
As a kind of improvement, described boiler tube is one.
As a kind of improvement, described boiler tube is provided with opening for feed at an end that stretches into described radiation chamber, is provided with discharge port at an end that stretches out described convection chamber.
As a kind of improvement, the radiation section that described boiler tube is positioned at described radiation chamber is identical with the bore of the convection zone that is positioned at described convection chamber.
As the design of routine, the utility model can optionally be equipped with chimney at the top of convection chamber, thereby realizes the drainage of flue gas.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
Boiler tube of the present utility model is light pipe, has improved the problem that traditional finned tube is tied carbon laydown easily, has improved boiler tube work-ing life; The radiation section that every boiler tube is positioned at described radiation chamber becomes the spiral raised shape around described burner, the convection zone that described boiler tube is positioned at described convection chamber is the Zigzag type shape of level, take full advantage of fume afterheat, improve the tube furnace efficiency of energy utilization, effectively increase thermo-efficiency, improve the heating quality to coal tar.
Boiler tube of the present utility model is provided with opening for feed at an end that stretches into described radiation chamber, be provided with discharge port at an end that stretches out described convection chamber, namely adopted the mode of material bottom in and top out, even if mass flow increases, flow velocity strengthens, still can guarantee the residence time of material in boiler tube, it is more abundant to make it to be heated, and has increased the thermo-efficiency of tube furnace.
Convection zone of the present utility model is identical with the radiant coil bore, and resistance to flow reduces, and can reduce knot carbon phenomenon simultaneously, improves boiler tube work-ing life.
