Abstract
The invention discloses a variable-diameter connecting tube with a flue gas flow guiding device. The flue gas flow guiding device is arranged inside the variable-diameter connecting tube, and structurally comprises a front-end flow stirring plate assembly and a tail-end flow stabilizing plate which are sequentially arranged at two ends of the variable-diameter connecting tube in the flow direction of flue gas, wherein the front-end flow stirring plate assembly has the structure as follows: a plurality of retainer rings are arranged inside the variable-diameter connecting tube; an installing base is arranged inside the innermost retainer ring; turbulence zones are formed between adjacent retainer rings, between the outmost retainer ring and the tube wall of the variable-diameter connecting tube, and between the installing base and the innermost retainer ring respectively; a plurality of flow stirring plates with the same inclining direction are arranged inside ach turbulence zone; the inclining directions of the flow stirring plates in the adjacent turbulence zones are opposite; and the tail-end flow stabilizing plate is a grid-type plate. The variable-diameter connecting tube with the flue gas flow guiding device has the advantages that high-temperature flue gas has a uniform flow distribution; and the heat efficiency of a flue gas heating device can be effectively improved.
Description
Technical field
The present invention relates to field of boilers, relate in particular to chimney intake in the heat transmission equipment that utilizes waste gas heating in the field of boilers pipeline configuration between exporting with the boiler high temperature exhaust emissions.
Background technology
Be accompanied by the implementation energetically of energy-saving and emission-reduction policy, boiler industry is more and more paid attention to the utilization of high-temperature tail gas, can install the device of exhaust boiler or other waste gas heat exchange usually additional, improves the overall thermal efficient of boiler, reduces energy resource consumption and carbon emission.
In actual the use, the chimney intake caliber on exhaust boiler or other waste gas heat-exchanger rig is different with the outlet caliber of boiler high temperature exhaust emissions, uses taper reducing tube connector to connect between the two usually.Import department's bore of taper reducing tube connector is little; The exit bore is big; Make the flue gas flow in centre position, reducing tube connector exit concentrate, the few and dispersion of outside flow, so the flow of flue gas in reducing tube connector exit is inhomogeneous; Thereby cause the heat exchange of the heat-transfer surface in exhaust boiler or other waste gas heat-exchanger rig uneven easily, adverse consequences such as thermal efficiency decline even localized heat transfer deterioration.
Summary of the invention
The objective of the invention is: a kind of reducing tube connector that can discharge the band flue gas guiding device of even, the stable flue gas that flows is provided.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: the reducing tube connector of band flue gas guiding device; In the reducing tube connector, be provided with the flue gas guiding device; The structure of described flue gas guiding device comprises: the front end spoiler assembly and the terminal stabilier that are successively set on reducing tube connector two ends along the flow of flue gas direction; The structure of described front end spoiler assembly is: in the reducing tube connector, be provided with some roads back-up ring, be provided with mount pad in the road back-up ring in, between the described adjacent back-up ring, between the tube wall of outermost back-up ring and reducing tube connector and mount pad and form turbulent flow area respectively between the back-up ring of inboard; Evenly be provided with the consistent spoiler of some incline directions in described each turbulent flow area, and the incline direction of the spoiler in the adjacent turbulent flow area is opposite; Described terminal stabilier is a flase floor.
Advantage of the present invention is: the reducing tube connector that has used band flue gas guiding device of the present invention; The high-temperature flue gas that gets in the reducing tube connector produces turbulent flow uniformly through front end spoiler assembly earlier; Pass through flase floor again; Then flow distribution is even for the high-temperature flue gas that comes out from the reducing tube connector like this, can effectively improve the heat exchange efficiency of waste gas heat-exchanger rig.
Description of drawings
Fig. 1 is the structural representation of the reducing tube connector of band flue gas guiding device of the present invention.
Fig. 2 is the front end guiding subassembly structural representation among Fig. 1.
Fig. 3 is the structural representation of the terminal stabilier among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the present invention is done further detailed description.
Like Fig. 1, Fig. 2, shown in Figure 3; The reducing tube connector of band flue gas guiding device; In reducing tube connector 1, be provided with the flue gas guiding device; The structure of described flue gas guiding device comprises: the front end spoiler assembly 2 and terminal stabilier 3 that are successively set on reducing tube connector 1 two ends along the flow of flue gas direction; The structure of described front end spoiler assembly 2 is: in reducing tube connector 1, be provided with the twice back-up ring, by outside to inside being first back-up ring 4 and second back-up ring 5 successively, the quantity of described back-up ring can be confirmed according to the caliber size of reducing tube connector 1.Be provided with mount pad 6 in second back-up ring 5; Form three road turbulent flow areas 7 between described first back-up ring 4 and second back-up ring 5, between first back-up ring 4 and reducing tube connector 1 tube wall and between the mount pad 6 and second back-up ring 5; Evenly be provided with the consistent spoiler 8 of some incline directions in described each turbulent flow area 7, and the incline direction of the spoiler 8 in the adjacent turbulent flow area 7 is opposite; As shown in Figure 3, described terminal stabilier is a flase floor 9.
During work; High-temperature flue gas enters in the reducing tube connector 1 because the front end of reducing tube connector 1 is provided with front end spoiler assembly 2, high-temperature flue gas in the three road turbulent flow areas 7 through and by the spoiler 8 in each turbulent flow area 7 respectively flow-disturbing form uniform turbulent flow; Turbulent flow is through terminal flase floor 9 uniformly; Form the equally distributed high-temperature flue gas of flow, the equally distributed high-temperature flue gas of flow enters into the waste gas heat-exchanger rig and carries out heat exchange, can effectively improve the heat exchange efficiency of waste gas heat-exchanger rig.
