Abstract
The utility model discloses a back wall flue of a hearth of a biomass energy boiler. The back wall flue comprises a flue, wherein one side of the upper part of the flue is provided with an elbow, one side of the bottom part of the flue is provided with a bulge of which the section is in a triangular shape, the bulge protrudes out of the side wall of the flue, the upper edge of the bulge is connected with the side wall of the flue, the lower edge of the bulge is connected to the bottom surface of the flue obliquely, an oblique plate is obliquely arranged at the bulge in the flue, one end of the oblique plate is connected to the bottom surface of the flue, and the other end of the oblique plate is connected to the connecting part between the bulge and the side wall of the flue. The back wall flue provided by the utility model can effectively avoid secondary combustion of ash, the ash is prevented from accumulating in the corner of the flue, thus avoiding the secondary combustion, the flue cannot be blocked easily, the operation cycle of the flue is prolonged, and the maintenance problem caused by blocking is reduced.
Description
Technical field
The utility model relates to field of boilers, especially relates to the rear wall flue of boiler.
Background technology
The rear wall flue of existing boiler, generally be provided with bend pipe in upper left-hand, and flue comprises flue bottom surface and sidewall.It is leg-of-mutton projection that flue bottom one side is provided with cross sectional shape.During work, the remaining particle that burns can be discharged from flue, but because the existence of projection, ash particles can be piled up high spot, and because the temperature of flue is very high, ashes can produce second-time burning, cause the flue-gas temperature of discharging too high.
The utility model content
The purpose of this utility model is to provide a kind of biomass energy boiler Novel hearth rear wall flue, prevents that flue-gas temperature is too high.
The technical solution of the utility model is:
Biomass energy boiler Novel hearth rear wall flue, comprise flue, described flue top one side is provided with bend pipe, it is leg-of-mutton projection that described flue bottom one side is provided with cross sectional shape, the sidewall of the outwardly flue of described projection, and the upper edge of projection is connected on the sidewall of flue, the lower edge of projection tilts to be connected on the flue bottom surface, described high spot tilts to be provided with swash plate in flue, and described swash plate one end connects the flue bottom surface, and the other end is connected to the junction of projection and flue sidewall.
Described swash plate and flue bottom surface have angle, and described corner dimension is 30 ° ~ 40 °.
Described corner dimension is 30 °.
The utility model has effectively been avoided the second-time burning of ashes, prevents that it is deposited in the turning of flue, thereby has avoided second-time burning, makes flue be difficult for stopping up, and has extended the cycle of operation of flue, reduces the maintenance problem that brings due to obstruction.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises flue 1, and flue 1 upper left-hand is provided with bend pipe 2, and it is leg-of-mutton protruding 3 that flue 1 bottom one side is provided with cross sectional shape.Flue 1 comprises flue bottom surface 7 and sidewall 8.
The sidewall 8 of projection 3 outwardly flues 1, the upper edge 4 of projection 3 connects the left side sidewall 8 of flue 1, the lower edge 5 of projection tilts to be connected on the flue bottom surface 7 of flue 1, lower edge 5 is 12 ° with the angle of flue bottom surface 7, at flue internal projection place, tilt to be provided with swash plate 6, swash plate 6 lower ends connect on flue bottom surface 7, and upper end is connected to the junction of projection 3 and flue sidewall 8.
Swash plate 6 has angle with flue bottom surface 7, and corner dimension is 30 ° ~ 40 °, corner dimension be 30 ° better, ashes can be slipped on flue bottom surface 7 along swash plate 6, and can not continue to be deposited in projection 3.The angle of inclination of swash plate 6 is larger, and ashes are not easy to be deposited on swash plate 6, even there is certain accumulation also can under Action of Gravity Field, slide, and no longer forms and piles up.
