Abstract
The utility model discloses a novel waste heat boiler which comprises a gas inlet end, a guard board, a thermal insulating layer, pipe plates, heat exchange pipes, a boiler body, a gas outlet end, water inlets and a steam outlet, wherein the pipe plates are arranged at both ends of the boiler body. The guard board is arranged on the outer side of a left side pipe board, the thermal insulating layer is arranged on the outer wall of the guard board, the left end of the guard board and the left end of the thermal insulating layer are the gas inlet end, multiple steam outlets are arranged at the top of the boiler body, multiple water inlets are arranged on the side edge of the boiler body, multiple heat exchange pipes are arranged in the boiler body in an axial mode, and the gas outlet end is arranged at the right end of the boiler body. A flexible thin pipe plate has good flexibility, so that over-high mechanical stress and differential temperature stress are relieved, and equipment strength and service life are greatly improved.
Description
Technical field
The utility model relates to a kind of boiler, be specifically related to a kind of novel waste heat boiler.
Background technology
Waste heat boiler has obtained more and more widely application as a kind of important energy saving equipment.Waste heat boiler often is under the harsh operating condition works, tube sheet as the waste heat boiler critical component, high-temperature technology gas arrival end tube sheet particularly, because bigger pressure and temperature loading are born in its both sides, tube sheet not only will satisfy the requirement of strength under the pressure effect, also must satisfy the thermal stress that causes because of housing and tube bundle heat differential expansion and the thermal stress requirement of tube sheet self.Therefore, tube sheet and housing connecting portion are the keys of waste heat boiler Intensity Design.Traditional waste heat boiler greatly reduces its intensity and service life because pressure differential and temperature difference that its tube sheet bears are all bigger.
Summary of the invention
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of novel waste heat boiler, its Methodology for Flexible Thin Tube Sheet has good flexible, thereby too high mechanical stress and thermal (temperature difference) stress have been alleviated, and the thermal stress of tube sheet itself also reduces greatly, has improved equipment intensity and service life greatly.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of novel waste heat boiler, comprise gas inlet end, backplate, thermal insulation layer, tube sheet, heat exchanger tube, body of heater, gas outlet end, water inlet and steam (vapor) outlet, the body of heater two ends are provided with tube sheet, left side tube sheet arranged outside has backplate, the backplate outer wall is provided with thermal insulation layer, backplate and thermal insulation layer left end are gas inlet end, the body of heater top is provided with a plurality of steam (vapor) outlets, the body of heater side is provided with a plurality of water inlets, the body of heater inner shaft is to being provided with a plurality of heat exchanger tubes, and the body of heater right-hand member is provided with gas outlet end.
Described tube sheet end is provided with protection tube.
Described tube sheet is the Methodology for Flexible Thin Tube Sheet structure.
Methodology for Flexible Thin Tube Sheet of the present utility model has good flexible, thereby has alleviated too high mechanical stress and thermal (temperature difference) stress, and the thermal stress of tube sheet itself also reduces greatly, has improved equipment intensity and service life greatly.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Coding among the figure is respectively: 1 is gas inlet end, and 2 is backplate, and 3 is thermal insulation layer, and 4 is tube sheet, and 5 is heat exchanger tube, and 6 is body of heater, and 7 is gas outlet end, and 8 is water inlet, and 9 is steam (vapor) outlet.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, this novel waste heat boiler, comprise gas inlet end 1, backplate 2, thermal insulation layer 3, tube sheet 4, heat exchanger tube 5, body of heater 6, gas outlet end 7, water inlet 8 and steam (vapor) outlet 9, body of heater 6 two ends are provided with tube sheet 4, left side tube sheet 4 arranged outside have backplate 2, backplate 2 outer walls are provided with thermal insulation layer 3, backplate 2 and thermal insulation layer 3 left ends are gas inlet end 1, body of heater 6 tops are provided with a plurality of steam (vapor) outlets 9, body of heater 6 sides are provided with a plurality of water inlets 8, body of heater 6 inner shafts are to being provided with a plurality of heat exchanger tubes 5, and body of heater 6 right-hand members are provided with gas outlet end 7.
As shown in Figure 1, described tube sheet 4 ends are provided with protection tube, and for reducing the wall temperature of tube sheet, it is overheated to prevent, has laid thermal insulation layer 3 before tube sheet.
As shown in Figure 1, described tube sheet 4 is the Methodology for Flexible Thin Tube Sheet structure.
The tube sheet of this specific embodiment is compared with general tube sheet, and the cylindrical shell pipe nipple of this tube sheet outer shroud and shell side, tube side is integral, and its periphery has all adopted bigger corner transition with the cylindrical shell pipe nipple, and outer shroud and interior ring adopt level and smooth butt welding.Design not only makes the tube sheet attenuation like this, has reduced the temperature difference of tube sheet both sides, and the periphery that tube sheet is connected with housing has bigger flexibility, has improved the force-bearing situation of tube sheet.So the design's tube sheet not only can bear bigger pressure, can also compensate the thermal (temperature difference) stress between heat-exchanging tube bundle and the housing, and forging ' s block dimension is reduced, weight saving.
The Methodology for Flexible Thin Tube Sheet of this specific embodiment has good flexible, thereby has alleviated too high mechanical stress and thermal (temperature difference) stress, and the thermal stress of tube sheet itself also reduces greatly, has improved equipment intensity and service life greatly.
