Abstract
The utility model discloses a diameter-reducing connecting pipe with a smoke air guiding device. The diameter-reducing connecting pipe is internally provided with the smoke air guiding device; and the structure of the smoke air guiding device comprises a front end intercepter assembly and a tail end steady flow plate which are sequentially arranged at the two ends of the diameter-reducing connecting pipe along a smoke flow direction; the structure of the front end intercepter assembly is as follows: the diameter-reducing connecting pipe is internally provided with a plurality of check rings, and the most inner check ring is internally provided with an installing base; turbulent flow regions are respectively formed between the adjacent check rings, between the most outer side check ring and the pipe wall of the diameter-reducing connecting pipe and between the installing base and the most inner side check ring; and each turbulent flow region is internally uniformly provided with a plurality of turbulent flow plates which have the same vergence direction, the vergence directions of the turbulent flow plates in the adjacent turbulent flow regions are opposite, and the tail end steady flow plate is a grid plate. The diameter-reducing connecting pipe provided by the utility model has the advantages that the high temperature smoke flow is uniformly distributed, and the heat efficiency of a waste gas heating device is effectively improved.
Description
Technical field
The utility model relates to field of boilers, relates 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.
The utility model content
The purpose of the utility model 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 utility model 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.
The utility model has the advantages that: the reducing tube connector that has used the described band flue gas of the utility model guiding device; 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 the described band flue gas of the utility model guiding device.
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 utility model is done further to specify.
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 3 is a flase floor.
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 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.
