The problem of cooperation heat transfer accumulation of energy sand carries out cold and hot exchange, reduces traditional heat exchangers intermediate heat transfer media fluid interchange inefficiency,
Shorten heat transfer process and lower heat waste, improves heat exchange efficiency.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes sealing heat exchange box, exhaust gas connection
Plate, S-shaped flue gas leading, offgas outlet, S-shaped air inlet pipe, heat transfer filling sand, insulation board, filtered air inlet, gas outlet；Described is close
The intermediate upper end of envelope heat exchange box is provided with exhaust gas connecting plate, and the lower end of exhaust gas connecting plate is connected with several S-shaped flue gas leadings side by side, and
The tail portion of S-shaped flue gas leading is connect with the offgas outlet of the upper end-face edge of sealing heat exchange box；In the interval trough of the S-shaped flue gas leading
Be interspersed with the S-shaped air inlet pipe successively folded, the both ends of the S-shaped air inlet pipe respectively with sealing heat exchange box front-rear side walls
Filtered air inlet is connected with gas outlet；And it is husky filled with heat transfer filling between S-shaped flue gas leading and S-shaped air inlet pipe, in addition, sealing is changed
The inner wall of hot tank is provided with insulation board.
Preferably, at left and right sides of the described sealing heat exchange box structure among exhaust gas connecting plate for symmetrical structure.
Preferably, the S-shaped flue gas leading and S-shaped air inlet pipe are all made of the sheet-metal duct of identical bore.
Preferably, the intake velocity of the S-shaped air inlet pipe is 1.5-2 times of S-shaped flue gas leading speed.
After adopting the above structure, the utility model has the beneficial effect that the novel exhaust gas of one kind described in the utility model changes
The interlaced of hot device, the heat pipe of its heat exchanger and cold pipe interts together, and heat transfer accumulation of energy sand is cooperated to carry out cold and hot exchange, subtracts
The problem of few traditional heat exchangers intermediate heat transfer media fluid interchange inefficiency, shortens heat transfer process, improves heat exchange efficiency.This
The advantages that utility model has structure simple, and setting is reasonable, low manufacture cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the inside top figure of the utility model.
Description of symbols:
Seal heat exchange box 1, exhaust gas connecting plate 2, S-shaped flue gas leading 3, offgas outlet 4, S-shaped air inlet pipe 5, heat transfer filling sand 6,
Insulation board 7, filtered air inlet 8, gas outlet 9
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1 and Figure 2, present embodiment adopt the following technical scheme that it include sealing heat exchange box 1, it is useless
Gas connecting plate 2, offgas outlet 4, S-shaped air inlet pipe 5, heat transfer filling sand 6, insulation board 7, filtered air inlet 8, goes out S-shaped flue gas leading 3
Port 9；The intermediate upper end of the sealing heat exchange box 1 is provided with exhaust gas connecting plate 2, and the lower end of exhaust gas connecting plate 2 connects side by side
There are several S-shaped flue gas leadings 3, and the tail portion of S-shaped flue gas leading 3 is connect with the offgas outlet 4 of the upper end-face edge of sealing heat exchange box 1；Institute
The S-shaped air inlet pipe 5 successively folded, the both ends of the S-shaped air inlet pipe 5 are interspersed in the interval trough for the S-shaped flue gas leading 3 stated
It is connect respectively with the filtered air inlet 8 of sealing 1 front-rear side walls of heat exchange box and gas outlet 9；And S-shaped flue gas leading 3 and S-shaped air inlet pipe 5
Between filled with heat transfer filling sand 6, in addition, sealing heat exchange box 1 inner wall be provided with insulation board 7.
Wherein, 1 left and right sides structure of sealing heat exchange box among exhaust gas connecting plate 2 for symmetrical structure；The S
Shape flue gas leading 3 and S-shaped air inlet pipe 5 are all made of the sheet-metal duct of identical bore；Conveniently regulating and controlling passes in and out the synchronously control of the rate of gas,
And heat transfer efficiency is greatly improved using thin-wall construction；The intake velocity of the S-shaped air inlet pipe 5 is 3 speed of S-shaped flue gas leading
1.5-2 again；Since S-shaped flue gas leading 3 is several short stroke pipes side by side, S-shaped air inlet pipe 5 is single long stroke pipe；Due to pipeline
The different regulations by intake velocity of stroke realize most efficient heat transfer efficiency, reduce heat loss.
The working principle of this specific embodiment:: the burning waste gas that annealing furnace generates is by being connected to exhaust gas connection after filtering
On plate 2 and importing in each S-shaped flue gas leading 3, heat is spread out on heat transfer filling sand 6 by hot waste gas through S-shaped flue gas leading 3,
Cold and hot exchange is realized to the transmitting of S-shaped air inlet pipe 5 from heat transfer filling sand 6 again.
After adopting the above structure, present embodiment has the beneficial effect that the heat pipe of its heat exchanger and the mutual friendship of cold pipe
Mistake is interspersed together, and heat transfer accumulation of energy sand is cooperated to carry out cold and hot exchange, reduces the fluid interchange of traditional heat exchangers intermediate heat transfer media
The problem of inefficiency, shortens heat transfer process, improves heat exchange efficiency.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
