Description
Technical field
The present invention relates to field of petrochemical industrial, burn reforming furnace more particularly, to a kind of side.
Background technique
The reforming furnace generallyd use in the catalytic reforming unit of petrochemical industry at present generally includes radiant section and convection current
Section.Wherein the radiating furnace tube in radiant section absorbs heat, provides heat for subsequent reactor, waste heat pot is usually arranged in convection section
Furnace recycles high-temperature flue gas, and the thermic load of radiant section is supplied by heating equipment (i.e. burner) the consumption fuel in burner hearth.It is existing
Reformer usually require multiple reactors, the corresponding heat absorption burner hearth of each reactor collectively forms series devices, wherein
Multiple heat absorption burner hearths integrate the reforming furnace of an All-in-One.
According to the difference of use demand, the existing All-in-One reforming furnace type of furnace is broadly divided into the just U-shaped furnace (figure of All-in-One
1a and Fig. 1 b) and All-in-One inverted U furnace (Fig. 2 a and Fig. 2 b), heat-supplying mode, which is predominantly held, burns heat supply and bottom burning heat supply.
As illustrated in figs. 1A and ib, just U-shaped reformer includes radiation chamber and convection cell 5, and wherein radiation chamber is rectangle furnace
1, rectangle furnace 1 is divided into multiple radiation cells by the internal multiple midfeathers 3 of setting, and multichannel is arranged in each radiation chamber
U-shaped coil pipe 2 in parallel, outlet, entrance and the radiation exhanst gas outlet of U-shaped coil pipe 2 are respectively positioned on radiating top, occupy headspace,
End can only be equipped in the different height at U-shaped 2 middle part of coil pipe and combust burner 4, generate horizontal flame in end, U-shaped coil pipe 2 is carried out
Burn heat supply in end.Its shortcoming is that the horizontal length of pipe row increases accordingly, the burner at both ends when U-shaped 2 number of coil pipe increases
Flame not can guarantee enough cascade units, and uneven heating even property of the pipe row along horizontal length direction increases, every road medium heat absorption
It measures inhomogeneities to increase, the tube wall temperature inhomogeneities that pipe arranges along horizontal length direction increases, therefore the coil pipe road of each burner hearth
Number is limited, and total caloric receptivity is limited, and according to the difference of technical load and coil lengths etc., needs to design the burning of different load
Device, specification and model are various.
As shown in Figure 2 a and 2 b, inverted U reformer includes radiation chamber and convection cell 10, and wherein radiation chamber is rectangle furnace
6, inside is arranged multiple midfeathers 8 and burner hearth is divided into multiple radiation cells, and multi-channel parallel inverted U disk is arranged in radiation chamber
Pipe 7, the outlet of inverted U coil pipe 7, entrance are located at radiation chamber bottom, and radiation exhanst gas outlet is located at radiating top.This structure can be in square
6 bottom cloth bottom set of shape burner hearth combusts burner 9, when being distributed in the centre of multi-channel parallel inverted U coil pipe 7, can form bottom and burn single side spoke
It penetrates, or is distributed in 7 straight pipe two sides of multi-channel parallel inverted U coil pipe, form asymmetrical bottom and burn double-side radiation.Its shortcoming is that
When burning single side radiation the bottom of using, the circumferential heating inhomogeneities of boiler tube can be increased, it is uneven to increase boiler tube circumferential direction tube wall temperature
Property, side towards the fire boiler tube tube wall temperature is much larger than the fiery face of back；When burner, which is distributed in boiler tube two sides, forms bottom burning double-side radiation, by
It is needed in intermediate combustion device while being the heat supply of arranged on left and right sides straight pipe, leading to the thermic load of intermediate combustion device is two sides burner
2 times, thermic load difference causes intermediate combustion device flame height to be about 2 times of two sides burner, forms to boiler tube asymmetric
Double-side radiation, equally also will increase the circumferential heating inhomogeneities of boiler tube, increase boiler tube circumferential direction tube wall temperature inhomogeneities, and
Need to design the burner of different load, specification and model are more；Since straight pipe height is usually higher, bottom combusts burner and is formed
Fire Radiation heat supply concentrate on burner hearth middle and lower part, uneven heat supply is generated along straight pipe short transverse to inverted U boiler tube, is increased
Boiler tube radial direction tube wall temperature inhomogeneities, boiler tube lower half portion tube wall temperature is significantly greater than top half, and increases fire box temperature
Unevenness vertically and degree.
In addition, no matter existing just U-shaped or inverted U reforming furnace, when need two-in-one, three-in-one or four-in-one
When, it is necessary to midfeather is set, each single radiation chamber is completely cut off.The masonry of midfeather is complex, and midfeather exists heated
The risk toppled over.Since the stability of midfeather is poor, it is difficult to keep stability in transit, therefore using integral module
When changing design and batch production manufacture, it is difficult to accomplish that factory builds, site operation masonry can only be remained.
Therefore, it is necessary to develop a kind of heat supply uniformly, boiler tube long service life, easy access and integral moduleization design and
The reforming furnace of batch production manufacture.
The information for being disclosed in background of invention part is merely intended to deepen the reason to general background technique of the invention
Solution, and it is known to those skilled in the art existing to be not construed as recognizing or imply that the information is constituted in any form
Technology.
