Description
Technical field
The utility model relates to a kind of heat recovery device, especially a kind of be used for radiant tube at a heat recovery device.
Background technology
At present, in the quantity-produced process, the annealing of metal is usually carried out in the tunnel type continuous annealing furnace, and combustible commonly used (as natural gas) burning comes to provide heat energy for the tunnel type continuous annealing furnace.Because the special atmosphere of annealing furnace domestic demand, so burning can not directly be carried out in stove, the general employing burnt in radiant tube, and its heat energy is radiated in the stove by the radiant tube tube wall again;
The flue-gas temperature very high (more than 1000 ℃) that radiant tube is discharged, if directly drain, energy waste is just very big.
How to reclaim the waste heat of this flue gas, existing is to adorn two accumulators at the exhaust opening of radiant tube, flue gas carries out heat exchange during by accumulator, heat energy is stored away,, stop accumulation of energy through the regular hour, in accumulator, feed the medium that needs heat energy again, carry out heat exchange, thereby the heat energy that makes in the accumulator to be held discharges, two accumulators are used alternatingly.Shortcoming is that control is complicated, and investment is high, poor reliability.Have plenty of centralized collection, be distributed to each point again and be used.Shortcoming is that pipeline is long, weak effect, and investment is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of radiant tube heat recovery device is provided, and in a recovery, in a utilization, need not control reduced investment.
The technical scheme that provides according to the utility model, described radiant tube heat recovery device comprises: mutually nested interior pipe and outer tube, and the air inlet of interior pipe protrudes an end of outer tube, and the gas outlet of interior pipe is positioned at the outer tube other end, the outer tube closed at both ends leaves a gas outlet; The blind end of pipe and outer tube inserts the gas outlet of radiant tube in described, and the air inlet of interior pipe and outer tube gas outlet are positioned at outside the radiant tube; Outer tube outer wall and radiant tube gas outlet seal by case, and described case is provided with flue gas discharge opening; The outer tube gas outlet is connected to the radiant tube air inlet by pipeline.
Can adopt flange bolt to connect between described case and the radiant tube gas outlet.
The utility model has the advantages that: simple in structure, easy to assembly, many radiant tubes produce waste heat at multiple spot, and the each point that produces waste heat can utilize again simultaneously, can carry out the saving utilization of the energy very efficiently.

Fig. 2 is the left view of Fig. 1.
Fig. 3 is the utility model user mode figure.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, 2: background radiation pipe heat recovery device comprises mutually nested interior pipe 1 and outer tube 2, and the air inlet 3 of interior pipe 1 protrudes an end of outer tube 2, and the gas outlet 4 of interior pipe 1 is positioned at outer tube 2 other ends, and outer tube 2 closed at both ends leave a gas outlet 5; The blind end of pipe 1 and outer tube 2 inserts the gas outlet of radiant tube 8 in described, and the air inlet 3 of interior pipe 1 and outer tube 2 gas outlets 5 are positioned at outside the radiant tube 8; Outer tube 2 outer walls and radiant tube 8 gas outlets are by case 6 sealings, and described case 6 is provided with flue gas discharge opening 7; Outer tube 2 gas outlets 5 are connected to radiant tube 8 air inlets by pipeline.
As shown in Figure 3, this device is contained in the flue gas outlet side of heat radiation tube 8.Adopt flange bolt to connect sealing between described case 6 and radiant tube 8 gas outlets.During burning, the high-temperature flue gas that radiant tube 8 is discharged carries out heat exchange with the air that enters in this device outside outer tube 2, flue gas after the exchange is discharged by flue gas discharge opening 7, and cold air burns to outer tube 2 becomes hot-air enters heat radiation tube 8 from outer tube 2 gas outlets 5 the other end and combustible (as natural gas) mixes through heating up after through interior pipe 1 in this device, thereby reaches in a purpose of recycling high-temperature flue gas heat energy.
The present invention is applied to the continuous annealing furnace of our company's galvanizing steel band and orientation silicon steel production line.Its actual heat energy recycle effect estimation is as follows:
Known:
1. the convective heat-transfer coefficient of flue gas is got α cigarette=30 (kcal/m2.h. ℃)
2. the convective heat-transfer coefficient of air is got α air=25 (kcal/m2.h. ℃)
3. stainless heat transfer coefficient is got k stainless steel=15 (kcal/m2.h. ℃)
4. the air year-round average temperature is 20 ℃
5. flue-gas temperature is 1000 ℃
6. every is 0.324m2 at a heat exchange area of heat recovery device, thickness of pipe wall 6mm.
7. our company is existing uses 96 of heat recovery devices, and system was produced in 300 days in annual 24 hours.
Ask:
1. every at the annual energy H who recycles of some heat recovery device
2. Wuxi China smart new material Co., Ltd is total to the total energy W that recycles thus the whole year
If: every energy recovery speed (kcal/h) of Q-at a heat recovery device
Separate:
1.Q=(1000-20)/[(1/0.324 * α cigarette)+(0.006/0.324 * k stainless steel)+(1/0.324 * α air)]
＝(1000-20)/[(1/0.324×30)+(0.006/0.324×15)+(1/0.324×25)]
＝980/[(1/0.324×30)+(0.006/0.324×15)+(1/0.324×25)]
＝980/[1/9.72+0.006/4.86+1/8.1]
＝4306(kcal/h)
(2.H=4306 kcal/h. only) * 24h/ days * 300 days
=31003200 (kcal/ only)
=4429 (kg mark coal/only)
3.W=4429 (kg mark coal/only) * 95
=420755 (kg marks coal)
=420.755 (ton mark coals)
From as can be seen last, energy-saving effect of the present invention is more considerable.
