It is connected between boiler tube ring by pipeline；Each boiler tube ring is communicated with each other by multiple U-shaped boiler tubes and is spliced；
If the radiation chamber bottom center, inner sidewall pass through bracket respectively vertically installs a burner, ring-type vertically
Dry burner, the combustor external are arranged insulating sleeve, specifically include the cylindrical sleeve for being located in the middle both ends open,
And two horn sleeve barrels at both ends are installed on, and smaller close to one end of cylindrical sleeve；
The convection current indoor location convection tube comprising several pipelines in double-helix, two neighboring double-helix pipe
The one end in road communicates with each other；Helical form installs several flow-stopping plates to the inner wall of the convection cell along its length, and two neighboring
Flow-stopping plate is staggered, and direction, on the contrary, one of them is tilted upward, another is diagonally downward.
More preferably, the boiler tube in the anti-coking tubular heater, extraneous air-source and outermost boiler tube ring connects
Logical, toward its interior infusion of air, calcination removes coking.
More preferably, the inner wall of the anti-coking tubular heater, the radiation chamber coats layer of reflective material.
More preferably, the anti-coking tubular heater, the barrel of the insulating sleeve are interior hollow double-layer structure, should
Hollow structure continues to be divided into 3 separate spaces by two pieces of thermal insulation boards, wherein filling with insulation material in intermediate separate space
Grain；Air is filled in other two separate space.
More preferably, the anti-coking tubular heater, the radiation chamber, convection cell inner wall be coated with heat-resisting material
Coating.
The utility model is include at least the following beneficial effects: the utility model is simple and compact for structure, is heated evenly, and avoids
As uneven heating it is even caused by coking, have good anti-coking effect.
The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through
Research and practice to the utility model and be understood by the person skilled in the art.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model anti-coking tubular heater；
Fig. 2 is the top view of all boiler tube rings in the utility model；
Fig. 3 is the structural schematic diagram of single boiler tube ring；
Fig. 4 is the sectional view of the barrel of insulating sleeve.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art referring to explanation
Book text can be implemented accordingly.
The utility model provides a kind of anti-coking tubular heater, as shown in Figure 1-3, from top to bottom successively include chimney 1,
Convection cell 2 and radiation chamber 3；
The radiation chamber 3 is cylindrical shape；The multiple boiler tube rings 4 being arranged inside and outside each other of the circumferential installation of installation in it, adjacent two
It is connected between a boiler tube ring 4 by pipeline；Each boiler tube ring 4 is communicated with each other by multiple U-shaped boiler tubes 5 and is spliced；The radiation
3 bottom center of room, inner sidewall pass through bracket (not illustrating in figure) respectively, and vertically one burner 9 of installation, ring-type are vertical several
Burner is arranged insulating sleeve 6 outside the burner 9, specifically includes the cylindrical sleeve for being located in the middle both ends open
610, and two horn sleeve barrels 620 at both ends are installed on, and smaller close to one end of cylindrical sleeve 610；
Convection tube 7 is installed in the convection cell 2 comprising several pipelines in double-helix, two neighboring double-helix
One end of pipeline communicates with each other；Helical form installs several flow-stopping plates 8 to the inner wall of the convection cell 2 along its length, and adjacent
Two flow-stopping plates 8 are staggered, and direction, on the contrary, one of them is tilted upward, another is diagonally downward.
The heating furnace of the utility model is arranged insulating sleeve 6 outside burner 9, and is set to include being located at centre
Cylindrical sleeve 610, and be installed on two horn sleeve barrels 620 at both ends, can be very good in this way by the heat of burner 9
Amount uniformly distributes, and reduces that different boiler tubes and burner distance are different and bring heats unevenly, such homogeneous heating
Property be greatly improved, also avoid that the same boiler tube is high close to the one side temperature of burner, and separate one side temperature is low,
And then avoid the coking because caused by heating is uneven；And flow-stopping plate 8 is set in convection cell 2, and by convection tube 7
Multiple double-helix pipeline connections are set as, also can be very good to guarantee heating uniformity, and heating effect is more preferable.
In another performance, the anti-coking tubular heater, extraneous air-source and outermost boiler tube ring
Boiler tube connection, toward its interior infusion of air, calcination removing coking, using air calcination, to burn up coking in boiler tube
Dirty matter.
The inner wall of another performance, the anti-coking tubular heater, the radiation chamber coats layer of reflective material.
Another performance, the anti-coking tubular heater, as shown in figure 4, the barrel of the insulating sleeve 6
610 be interior hollow double-layer structure, which continues to be divided into 3 separate spaces by two pieces of thermal insulation boards 12, wherein intermediate
Separate space in filling with insulation material particle 10；Air 11 is filled in other two separate space；In this way, heat-proof quality
More.
Without departing from the general concept defined in the claims and the equivalent scope, the utility model is not limited to specifically
Details and legend shown and described herein.
