Abstract

The invention relates to a fin heat exchanger of an air preheating device. The fin heat exchanger comprises fin sandwich units A and fin sandwich units B, wherein the fin sandwich units A and the fin sandwich units B are laminated alternately and are densely provided with fins for forming heat exchange passages; the fins of the fin sandwich units A and the fin sandwich units B are perpendicular to one another and are sectional fins; a plurality of adjacent sectional fins form a group; the sectioning positions of the fins in each fin group are the same so as to form a plurality of turbulent flow cavities perpendicular to the extension direction of the fins; the turbulent flow cavities in adjacent fin groups are crosswise distributed. The fin sandwich units A and the fin sandwich units B are made of corrosion-resistant cast iron plates. The fin heat exchanger has the beneficial effects that the heat exchanger has high heat exchange efficiency and small pressure drop, the fin sandwich units are manufactured by adopting the corrosion-resistant cast iron plates, the problem of dew point corrosion is effectively solved, and the flue gas exhaust temperature can be further reduced while the service life is guaranteed.

Description

A kind of finned heat exchanger of air preheater
Technical field
The present invention relates to a kind of finned heat exchanger of air preheater.
Background technology
High-temperature flue gas in petroleum chemical heating furnace needs to enter flue gas heat recovery and combustion air preheating by air preheater, the low-temperature zone finned heat exchanger of existing petroleum chemical heating furnace, there is dew point corrosion problem, the temperature of exiting flue gas cannot be reduced further, and comparatively large to the pressure drop of flue gas and combustion air, need to consume the more energy and flow in heat exchanger to drive flue gas and combustion air.
Summary of the invention
Technical problem to be solved by this invention is: the finned heat exchanger providing a kind of air preheater, reduces the pressure drop of heat exchanger, improves corrosion resistance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of finned heat exchanger of air preheater, comprise fin interlayer element A and fin interlayer element B, fin interlayer element A and fin interlayer element B is alternately laminated, fin interlayer element A and fin interlayer element B gathers and forms the fin of heat exchanger channels, fin interlayer element A is mutually vertical with the fin on fin interlayer element B, fin is segmented fin, adjacent multiple segmented fins are one group, the segmentation position of the fin in each fins set is identical, to form multiple flow-disturbing chamber vertical with fin bearing of trend, flow-disturbing chamber in adjacent fins group is interspersed.
For improving corrosion resistance, the material of fin interlayer element A and fin interlayer element B is corrosiron plate.
The invention has the beneficial effects as follows: this heat exchanger heat exchange efficiency is high, and pressure drop is little, by adopting corrosiron plate to make fin interlayer element, efficiently solving dew point corrosion problem, while ensureing service life, flue gas exit temperature can be reduced further.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described;
Fig. 1 is the structural representation of fin interlayer element of the present invention;
Fig. 2 is overall structure schematic diagram of the present invention
Wherein, 1. fin interlayer element A, 2. fin interlayer element B, 3. fin, 4. flow-disturbing chamber.
Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of finned heat exchanger of air preheater, comprise outer cover of heat exchanger and fin interlayer element A1, fin interlayer element B2, fin interlayer element A1 and fin interlayer element B2 is arranged in outer cover of heat exchanger, fin interlayer element A1 and fin interlayer element B2 is alternately laminated, fin interlayer element A1 and fin interlayer element B2 gathers and forms the fin 3 of heat exchanger channels, fin interlayer element A1 is mutually vertical with the fin 3 on fin interlayer element B2, fin 3 is segmented fin, adjacent multiple segmented fins are one group, the segmentation position of the fin 3 in each fins set is identical, to form multiple flow-disturbing chamber 4 vertical with fin 3 bearing of trend, flow-disturbing chamber 4 in adjacent fins group is interspersed.
The material of fin interlayer element A1 and fin interlayer element B2 is corrosiron plate.
