Description
Technical field
This utility model is related to a kind of off-gas recovery technology, and in particular to more than the flue gas of a kind of boiler or similar burner
Heat reclamation device.
Background technology
Traditional device for recovering waste heat of high-temperature flue volume is larger, and investment is big, is not suitable for being used on miniature boiler, existing
The miniature boiler unreasonable structure of technology, heat exchange efficiency is not enough, high fume temperature, and energy waste is big, and this utility model is provided
One volume compact, high-temperature flue gas recovering effect is good, invests little utility unit.
The content of the invention
For above-mentioned the deficiencies in the prior art, a kind of flue gas waste heat recovery apparatus are devised, solve small boiler and ask
Topic.
A kind of device for recovering waste heat of high-temperature flue, including box housing, are provided with flue, its feature in the box housing
It is to be provided with horizontal baffle in described box housing space in housing is divided into at least two flue layers, described each flue
Vertical partition plate being provided with layer, each flue layer is divided into at least two independent short flues, order head and the tail between each short flue
Connection, adjacent flue interlayer is provided with the heat-exchange finned tube parallel with flue by the short flue connection of head and the tail in described flue,
Fin is fixed with the heat-exchange finned tube.
Described device for recovering waste heat of high-temperature flue, is characterized in that being 90 degree of right angles between each adjacent fins in described fin
It is fixedly connected.
Described device for recovering waste heat of high-temperature flue, is characterized in that described flue layer for double-decker, each flue layer
The short flue of four order head and the tail connections is provided with, two flue interlayers are by the short flue connection of head/tail.
Device for recovering waste heat of high-temperature flue of the present utility model, by by flue layering, the short circuit in heat exchanger, reducing
Boiler floor space, heat-exchange finned tube is placed in flue, improves heat exchange efficiency, and according to on-the-spot test, exhaust gas temperature is close to big
Temperature degree.

Specific embodiment
With reference to embodiments and accompanying drawing elaborates to this utility model, high-temperature flue gas waste heat of the present utility model is returned
Receiving apparatus, including a box housing 1 made by steel plate, a horizontal baffle 7 are provided with box housing and are classified as
Upper and lower two flue layers, by three vertical partition plates 3 are classified as four parallel short flue layers, respectively respectively in each flue layer
Short flue interlayer order head and the tail are connected, and upper and lower two flue interlayers are also through the short flue connection of head and the tail.Along cigarette in box housing
Road trend is provided with parallel the heat-exchange finned tube 4 of copper or aluminium profile, some fins 2 is fixed with the heat-exchange finned tube, respectively
Arranged and fixed by 90 degree of right angles between adjacent fins, and be mutually linked between adjacent fins.Above-mentioned flue layer can arrange three layers
Or multilamellar, each short flue also can be arranged less than or greater than four, and depend on actual need flexible design.
When using, high-temperature flue gas are entered from the gas approach 9 of bottom, through by bottom and vertical partition plate 3, horizontal baffle 7
The return flue of lower floor three of composition, enters flat partition board 7 upper with what the vertical dividing plate 3 in upper strata was constituted through the exhanst gas outlet 11 of horizontal baffle
Three return flue of layer, flue gas is finally discharged from air vent 8；When the relatively low heating installation backwater of temperature enters heat exchange fin from return pipe 5
Pipe 4 exchanges heat with the heat exchange fin 2 for assembling on finned tube and the fin tube assembly being tightly cased with heat-exchange finned tube with high-temperature flue gas, this
Individual heat-exchange finned tube then goes to the backhaul of lower floor three along the backhaul of flue upper strata three, finally enters with boiler from the outlet 6 of return pipe
The mouth of a river connects, and high-temperature flue gas are absorbed through 6 backhauls and heat-exchange finned tube heat absorption heat exchange, substantial amounts of flue gas heat, smoke evacuation temperature
Degree is reduced, and return water temperature is raised, and realizes the purpose of energy-conservation.
