Description
Technical field:
The utility model relates to oil field injection boiler, in particular to a kind of injection boiler convection section.
Background technique:
In injection boiler convection section, what convection bank was all made of is the combining form of light pipe and finned tube, wherein fin
Pipe is made of the fin of light pipe and welding thereon as extended surface, can reduce the overall dimensions of convection section.But due to
The fuel of injection boiler is mainly heavy oil or residual oil, and the ash content contained is larger, is easy to form dust stratification on finned tube, increases biography
Thermal resistance, heat transfer property are deteriorated, and exhaust gas temperature increases, and heat loss increases, and the thermal efficiency reduces.
Utility model content:
The technical problem to be solved by the present invention is to provide a kind of injection boiler convection sections, and the arrangement achieves reductions pair
Section dust stratification is flowed, frequency of soot blowing is reduced, heat loss due to exhaust gas is reduced, improves the thermal efficiency of injection boiler, it is energy-saving.It overcomes existing
The easy dust stratification of injection boiler convection section, heat transfer resistance is big, and heat transfer property is poor, and high fume temperature, heat loss is big, and the thermal efficiency is low not
Foot.
Technical solution adopted in the utility model is: a kind of injection boiler convection section, including convection section cabinet and setting
In the convection bank of convection section box house；Chimney is arranged in convection section upper end, and changeover portion is arranged in convection section lower end, and flue gas is according to mistake
It crosses section, convection section, chimney to pass sequentially through, convection bank water supply flow direction is contrary with flow of flue gas；
Convection bank is made of light pipe tube bank and studded tube tube bank, and light pipe tube bank is located at below convection section cabinet, studded tube
It restrains and is located at light pipe tube bank top, light pipe tube bank is arranged 2-10 and arranges, and studded tube tube bank setting 10-24 is arranged, and studded tube is restrained every
2-4 row is that soot blowing space is arranged between one group, every group；Studded tube tube bank is made of base tube and ailhead, uniformly distributed on base tube outer surface
Ailhead.
Convection section preferably uses vertical structure.
Convection section preferably uses horizontal type structure.
Convection section cabinet design is one of square box, triangle cabinet, trapezoidal cabinet.
Ailhead outer diameter is 6-12mm, and ailhead length is 20-50mm.
The beneficial effects of the utility model are: the utility model, which realizes, reduces convection section dust stratification, frequency of soot blowing, drop are reduced
Low heat loss due to exhaust gas improves the thermal efficiency of injection boiler, energy-saving.
Detailed description of the invention:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the arrangement schematic diagram of the utility model.
Fig. 2 is the schematic diagram that convection section uses horizontal type structure.
Fig. 3 is the structural schematic diagram of the utility model.
Fig. 4 is the structural schematic diagram of studded tube tube bank.
Fig. 5 is that studded tube restrains cross-sectional view.
Specific embodiment:
As shown in Fig. 1, Fig. 3, Fig. 4, Fig. 5, a kind of injection boiler convection section, including convection section cabinet 1 and setting are in convection current
Convection bank inside section cabinet 1；Chimney 6 is arranged in convection section upper end, and changeover portion 7 is arranged in convection section lower end, and flue gas is according to transition
Section 7, convection section, chimney 6 pass sequentially through, and convection bank water supply flow direction is contrary with flow of flue gas；
Convection bank is made of light pipe tube bank 3 and studded tube tube bank 2, and light pipe tube bank 3 is located at 1 lower section of convection section cabinet, nail
Head tube tube bank 2 is located at 3 top of light pipe tube bank, and light pipe tube bank 3 avoids following closely for reducing the flue-gas temperature for entering studded tube tube bank 2
First 5 high temperature damage.Studded tube tube bank 2 can reduce the overall dimensions of convection section as extended surface, while reduce because of combustion
Dust stratification caused by burning heavy oil, residual oil, and flue gas heat is further absorbed, reduce exhaust gas temperature.3 setting 2-10 of light pipe tube bank
Row, studded tube are restrained 2 setting 10-24 and are arranged, and every 2-4 row of studded tube tube bank 2 is that soot blowing space is arranged between one group, every group；Nail
Head tube tube bank 2 is made of base tube 4 and ailhead 5, uniformly distributed ailhead 5 on 4 outer surface of base tube.
Convection section can use vertical structure.
As shown in Fig. 2, convection section can use horizontal type structure.
Convection section cabinet 1 is designed as one of square box, triangle cabinet, trapezoidal cabinet.
5 outer diameter of ailhead is 6-12mm, and 5 length of ailhead is 20-50mm.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
