Detailed description of the invention
See Fig. 1 and 2, show vertical outer circulation bent tube boiler of the present utility model.
Described vertical outer circulation bent tube boiler comprises cylindric boiler body 10, described boiler body 10 is provided with water inlet and delivery port, the inwall 11 of tubular is provided with in described boiler body 10, lower ending opening is provided with and the smoke chamber 12 of upper end closed in described inwall 11, the lower ending opening of described smoke chamber 12 is the entrance of flue gas, the middle part of described boiler body 10 is outward extended with the smoke box 13 of ring-type, described smoke chamber 12 is by being communicated in smoke box 13 after the through described inwall 11 of a fire hole circle 17, wherein, described fire hole circle 17 runs through the top of smoke box 13, the bottom of described smoke box 13 is communicated to flue 20 to discharge flue gas, many curved water pipes are provided with in described smoke box 13, the two ends of each described curved water pipe are communicated to the space in boiler body 10 inwall 11 from the upper and lower of smoke box 13 respectively, to carry out backwater, thus, after high-temperature flue gas enters smoke chamber 12, by the wall portion of smoke chamber 12, the space in inwall 11 is heated, by the flue gas in smoke box, the water in each curved water pipe is heated simultaneously, add radiation heating-surface and convection heating surface, correspondingly reduce the height of flue and furnace shell, more save space, and, heat absorption fully, exhaust gas temperature is lower, boiler efficiency is higher.
Wherein, in described smoke box 13, be provided with heat-insulation layer 14, improve endothermic effect.
Wherein, described many curved water pipes comprise many excurvation water pipes 15 and interior curved water pipe 16, described excurvation water pipe 15 is positioned at the outside of curved water pipe 16, and described excurvation water pipe 15 and interior curved water pipe 16 are alternately arranged in the smoke box 13 interior (as shown in Figure 2) of annular, this being arranged alternately further increases heating surface, improves efficiency.
Wherein, the middle part of described smoke box 13 is provided with and smoke box 13 is divided into upper and lower two-part insulating course 18, described insulating course 18 is provided with at the opposite side (being preferably 180 degree, interval) of relative fire hole circle 17 and is communicated with the two-part opening 19 of smoke box about 13, described flue 20 is arranged at the same side of fire hole circle 17, thus, in smoke box, smoke box is divided into upper and lower two parts by insulating course, high-temperature flue gas flow to foreign cigarette upper box part from burner hearth through fire hole circle 17, smoke box bottom is entered by the opening of insulating course after circulation 180 DEG C along about boiler jacket, flue is entered after circulation 180 DEG C about flue gas, again through energy-saving appliance, deduster, chimney enters air.
Wherein, the bottom of described smoke box 13 is provided with the shoot door 21 of 90 degree, four intervals arrangement, is beneficial to the deashing operation of smoke box.
Known by said structure, the utility model arranges curved water pipe at boiler exterior, because shell part is also heated, add radiation heating-surface and convection heating surface, correspondingly reduce the height of flue and furnace shell, be furnished with heat-insulation layer, heat absorption is more abundant, and exhaust gas temperature is lower, and boiler efficiency is higher.
Because in biomass fuel, some contains oil, be difficult to remove if be attached to fire tube inwall, time long easy plugging, and bent tube boiler is because flue gas is outside tube wall, convection current space is comparatively large, not easily works the mischief to boiler tube, and cleaning carbon distribution also facilitates.
High-temperature flue gas of the present utility model both heated boiler jacket in flue circulation outside shell, transversal flow makes again curved water pipe fully absorb heat, this just substantially improves heat transfer situation, evaporation capacity and efficiency can significantly improve, add that this boiler heating surface is arranged simple, comparatively multitubular boiler is good for the situations such as snaking ash disposal, and boiler steel consumption is also low than multitubular boiler, operation troubles rate is low, and maintenance and inspection are convenient.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the utility model do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of description and the appended claim fallen into above.
