Definitions
- the thermal cracking of hydrocarbons usually takes place in Pyrolysis furnaces.
- a conventional pyrolysis oven has a burner-heated one Radiation zone.
- the thermal cracking of the hydrocarbons is described in Canned tubes performed in the radiation zone.
- the splitting of hydrocarbons can be facilitated in that the hydrocarbons before the introduction into the Radiation zone are preheated in a convection zone of the pyrolysis furnace.
- a pyrolysis furnace with a canned arrangement of the type mentioned is in the EP 0 529 441 B1.
- this arrangement of the canned tubes shown as an example.
- the hydrocarbons to be split are made according to the Direction of arrow introduced into the pipes from above.
- the three groups of can are staggered (two 90 ° curves) by three, not shown Cracked gas cooler arranged before entering the radiation zone of the pyrolysis furnace into running.
- the cracked gas coolers are located in the extension of the three outlet pipes (in Arrows pointing in the Z direction).
- the dashed line symbolizes the upper end of the Radiation zone of the pyrolysis furnace.
- Pipe pieces of the canned tubes extend to the lower area of the radiation zone. There two canned tubes are combined to form a tube via a tube collecting piece. The resulting eight canned tubes per group merge into eight elbows four of which each have approximately the same direction of curvature. A certain one Deviation in the direction of curvature is due to the projections of the elbows conditionally.
- the straight pipe sections of the groups lie in the arrangement level of the Can (X / Z plane).
- the eight flowed straight through from bottom to top Pipe pieces in each group are initially made up of two using pipe collectors Canned pipes and combined via a further pipe header to form an outlet pipe.
- the cracked gas coolers (not shown) are located above the three outlet pipes straight extension of the outlet pipes.
- the invention is therefore based on the object of a pyrolysis oven at the outset to indicate the type mentioned, which avoids this disadvantage.
- Characteristic of the pyrolysis furnace according to the invention that each with the help the pipe bend made from a first S-shaped bend leads out of the plane with the straight pipe sections and the pipe collecting sections, then with a semicircular or a flatter semi-elliptical or semi-oval arch slants the plane and finally over a second S-shaped Leads the arch back into the plane.
- the change of direction takes place in a sweeping arc, which is the plane which cuts straight pipe sections at a flat angle.
- the sweeping one Bow allows a particularly low-tension assembly.
- the pipe sections in front of the Reversal of direction and the pipe sections after the reversal take in the Level two adjacent faces one by the faces opposite burners, possibly different, are heated can.
- the S-shaped, semicircular, semi-elliptical or semi-oval arches of one Groups can be geometrically identical. Such an execution the arches enables savings in manufacturing and maintenance costs.
- the semicircular, semi-elliptical or semi-oval arches of a group can cut the plane with the straight pipe sections at the same angle.
- the advantage is that at a small angle, the arches are close together, the Support radiation tubes against each other and thereby also the function of an otherwise with the necessary complex positioning system.
- FIG. 2 schematically shows a side view of the can arrangement Pyrolysis furnace according to the invention.
- the pipe run is just one Canned tube group shown in the lower part of the radiation zone of such a furnace.
- two of sixteen canned tubes 1 are connected to one via a tube collecting piece 2 Tube united.
- the resulting eight pipes each go into an S-shaped bend 3, then in a semi-oval 4, then again in an S-shaped sheet 5 and finally into a pipe section 6, ie a total of eight straight pipe sections.
- the canned tubes are straight, parallel and vertical in the pyrolysis furnace arranged pipe sections and with the pipe collectors in one plane. Overall, at the transition of the canned tubes into the eight straight tube sections the pipe bends reversed direction. In Figure 2 it is not shown that these eight straight pipe sections after leaving the radiation zone to one or several fission gas coolers are performed.
- FIG. 3 a top view of what is shown in FIG demonstrated that two canned tubes 1 are combined, via an S-shaped Lead out bend 3 from level 7 with the straight pipe sections, with a subsequent arc (180 °) cut level 7 and finally with one return another S-shaped arch to level 7.
