Abstract

The utility model discloses a hot-blast exchanging apparatus of fuel heating, which includes a heater hearth, a heat exchanger, a conduct plate, a filter, an insert cycle fan, an outer wall plate, an inner wall plate, a preservation layer, and a replacement gate of the heat exchanger. The heat exchanger consists of an inlet wind channel, a main heat exhaust pipe, a hot blast channel, an associate heat exhaust pipe, and an outlet wind channel. The inlet of the inlet wind channel is communicated with the heater hearth; the outlet of the inlet wind channel is communicated with the inlet of the main heat exhaust pipe, the outlet of which is communicated with the inlet of the hot blast channel, the outlet of which is communicated with the inlet of the associate heat exhaust pipe, the outlet of which is communicated with the outlet wind channel. The hot-blast exchanging apparatus of fuel heating has low production costs but high heat efficiency.

Description

The fuel Heating hot-blast heat exchange device
Technical field
The utility model relates to a kind of heat-exchanger rig that the hot-blast stove of cleaning, high-temperature hot air is provided, especially fuel Heating hot-blast heat exchange device.
Background technology
At present, used hot-blast stove is a kind of thermal hardware that cleaning, high-temperature hot air are provided in the production process of automobile, household electrical appliances application, oil and foodstuffs processing, feed processing, marine product processing, sugar industry and paper-making industry, be characterized in that quick heating, hot-air cleaning is clean, more energy-conservation than electric heating equipment, compare with the boiler drying plant that to have price low, floor space is little, and fitting operation is convenient.The heat exchanger tube that this equipment heat exchanger adopts is the engineering pipe, because the tube wall of engineering pipe is thicker, in order to improve heat exchange efficiency, need the tube wall tension-thining, this will increase production cost, simultaneously owing to high temperature hot gas enters, exports discharge from the heat exchanger tube import of heat exchanger, its stroke is short, heat exchanger time is not long, and is higher from the flue-gas temperature that the heat exchanger tube outlet is discharged, so heat exchange efficiency is low.
The utility model content
The purpose of this utility model is to provide a kind of fuel Heating hot-blast heat exchange device, and this fuel Heating hot-blast heat exchange device production cost is low, thermal efficiency height, and the flue-gas temperature of discharge is low.
Technical solution of the present utility model is: contain the burner burner hearth, heat exchanger, deflector, filter, the plug-in type circulating fan, exterior panel, inside panel, heat-insulation layer, heat exchanger is changed door, heat exchanger is by airintake wind-tunnel, main radiating tube, hot-air channel, secondary radiating tube, outgassing wind-tunnel constitutes, the import of airintake wind-tunnel and burner burner hearth link, the outlet of airintake wind-tunnel and main radiating tube import link, the outlet of main radiating tube and hot-air channel import link, the outlet of hot-air channel and secondary radiating tube import link, and secondary radiating tube outlet links with outgassing wind-tunnel.
Main radiating tube cross section is a quadrangle.
Secondary radiating tube cross section is a rectangle.
Secondary radiating tube cross section is oval.
The beneficial effects of the utility model are, because heat exchanger adopts major and minor radiating tube, prolong the stroke that hot blast passes through, and heat exchanger time is long, thermal efficiency height.Owing to the simple shape of major and minor radiating tube, production process is few again, and production technology is simple, thereby production cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
1. burner burner hearths among the figure, 2. deflector, 3. filter, 4. plug-in type circulating fan, 5. exterior panel, 6. inside panel, 7. heat-insulation layer, 8. heat exchanger is changed door, 9. outgassing wind-tunnel, 10. main radiating tube, 11. secondary radiating tubes, 12. hot-air channels, 13. airintake wind-tunnels.
The specific embodiment
Among Fig. 1 and Fig. 2, the import of airintake wind-tunnel 13 and burner burner hearth 1 link, the import of the outlet of airintake wind-tunnel 13 and main radiating tube 10 links, the import of the outlet of main radiating tube 10 and hot-air channel 12 links, the import of the outlet of hot-air channel 12 and secondary radiating tube 11 links, the outlet and the outgassing wind-tunnel 9 of secondary radiating tube 11 link, one side of burner burner hearth 1 is provided with deflector 2, one side of deflector 2 is provided with filter 3, the wallboard of filter 3 one sides is provided with plug-in type circulating fan 4, wallboard is by exterior panel 5, inside panel 6 and heat-insulation layer 7 constitute, and heat-insulation layer 7 is arranged between inside panel 6 and the exterior panel 5.Among Fig. 2 and Fig. 3, heat exchanger is set on the sidewall paneling of hot-air channel 12 changes door 8.
During work, the high temperature hot gas of burner burner hearth enters in the main radiating tube 10 by airintake wind-tunnel 13, the temperature of main radiating tube 10 is raise, high temperature hot gas enters in the hot-air channel 12 subsequently, then enter in the secondary radiating tube 11, the temperature of secondary radiating tube 11 is raise, entering outgassing wind-tunnel 9 at last discharges, because the stroke that high temperature hot gas is passed through has increased by one times, thereby heat exchanger time is long, because area of dissipation increases, heat exchange is abundant simultaneously, the flue-gas temperature of discharging by outgassing wind-tunnel 9 is low, so thermal efficiency height.Meanwhile, air is entered to contact with secondary radiating tube 11 with main radiating tube 10 by the import of radiator top and carries out heat exchange with it, air themperature raises, the diversed plate 2 of high temperature air stops, thereunder flow through, high temperature air is by after the filtration of filter 3, and the hot-air of cleaning, high temperature is extracted out by plug-in type circulating fan 4 and entered subsequent processing.
