Abstract
The utility model relates to a waste heat recovery and utilization device, in particular to a flue gas waste heat recovery device, and solves the problem of the conventional flue gas waste heat recovery device that the waste heat recovering efficiency is lower. The flue gas waste heat recover device provided by the utility model comprises a flue gas collecting box; a flue gas inlet, a flue gas outlet, an inlet for a medium to be heated, and an outlet for the medium are formed on the flue gas collecting box; partition boards are fixed on the flue gas inlet and the flue gas outlet of the flue gas collecting box; a plurality of rows of radiating pipes are fixed between the two partition boards; and radiating fins are fixed on the radiating pipes in a radial or helicoidal manner. As the radiating fins are additionally arranged on the radiating pipe, the utility model has the advantages that the heat exchange area of the radiating pipe is enlarged, and heat exchange between the radiating pipes and the medium to be heated is improved, thereby improving the waste heat recovering efficiency of the flue gas waste heat recover device. Compared with the conventional similar products, the waste heat recovering efficiency of the flue gas waste heat recover device is greatly improved, so that the flue gas waste heat recover device is suitable for recovering and utilizing waste heat of various flue gases and tail gases, and particularly suitable for recovering and utilizing waste heat of the flue gas of a gas generating set.
Description
Technical field
The utility model relates to the heat recovery device, is specially a kind of flue gas waste heat recovery apparatus.
Background technology
Existing flue gas waste heat recovery apparatus comprises the collection smoke box, and the collection smoke box is provided with flue gas import and export and heated medium import and export, is fixed with dividing plate on the flue gas import and export of collection smoke box, is fixed with many row's radiating tubes between two dividing plates.Flue gas enters from gas approach, discharges to exhanst gas outlet through the radiating tube inner chamber; Heated medium (air, other gas or water etc.) enters from the heated medium import, fully contacts with each radiating tube surface and realizes exporting discharge from heated medium after the exchange heat, thereby realized the recycling of fume afterheat.Existing flue gas waste heat recovery apparatus is owing to structural defective, and waste heat recovery efficient is lower.
Summary of the invention
The utility model provides a kind of waste heat recovery efficient high flue gas waste heat recovery apparatus in order to solve the existing lower problem of flue gas waste heat recovery apparatus waste heat recovery efficient.
The utility model is to adopt following technical scheme to realize: flue gas waste heat recovery apparatus, comprise the collection smoke box, the collection smoke box is provided with flue gas import and export and heated medium import and export, is fixed with dividing plate on the flue gas import and export of collection smoke box, is fixed with many row's radiating tubes between two dividing plates; Be fixed with radiating fin on the radiating tube.Set up radiating fin on the radiating tube, increased the heat exchange area of radiating tube, improved the heat-exchange capacity between radiating tube and heated medium, thereby improved the waste heat recovery efficient of flue gas waste heat recovery apparatus.
Flue gas waste heat recovery apparatus described in the utility model is compared with existing like product, and under the identical situation of heat exchange efficiency, it is little that device has a volume, and compact conformation is not fragile, the characteristics that heat exchange property is good; The reducing of volume providing bigger space to the user aspect apparatus arrangement and the installation; Under the identical situation of volume, heat exchange efficiency is greatly improved (about 8 times), and the afterheat utilization rate reaches 80-90%.Flue gas waste heat recovery apparatus described in the utility model is applicable to the heat recovery of various flue gases, tail gas, be particularly useful for the recycling of the fume afterheat of gas electricity unit, be installed on the smoke exhaust pipe of gas electricity unit during use and fix with steelframe firmly.This installs all parts all is that welding combines, and does not have the rapid wear accessory, uses reliably, is convenient to maintenance.
Description of drawings
Fig. 1 is the structural representation of flue gas waste heat recovery apparatus described in the utility model;
Fig. 2 is a kind of concrete structure schematic diagram of the radiating tube that has radiating fin in the flue gas waste heat recovery apparatus described in the utility model;
Among the figure: 1-collection smoke box, 2-gas approach, 3-exhanst gas outlet, the import of 4-heated medium, the outlet of 5-heated medium, 6-dividing plate, 7-radiating tube, 8-radiating fin.
The specific embodiment
Flue gas waste heat recovery apparatus comprises collection smoke box 1, and collection smoke box 1 is provided with flue gas import and export 2,3 and heated medium import and export 4,5, is fixed with on the flue gas import and export 2,3 of collection smoke box 1 and is fixed with many row's radiating tubes 7 between dividing plate 6, two dividing plates; Be fixed with radiating fin 8 on the radiating tube 7.During concrete the manufacturing, described radiating fin 8 is radial and is fixed in (as shown in Figure 2) on the radiating tube 7, and this kind structure is applicable to that heated medium is liquid (as a water), can reduce the resistance of liquid flow; Perhaps described radiating fin 8 shape in the shape of a spiral is fixed on the radiating tube 7, and this kind structure is applicable to that heated medium is gas (as an air), helps reducing the flow resistance of air.Further, adjacent two row's radiating tubes are staggered to be arranged, and promptly each radiating tube of row further improves heat exchange effect with this between two adjacent radiating tubes of last row's radiating tube down.
