Detailed description of the invention
With reference to figure 1, the vehicle furnace drying system in the present embodiment comprises: waste gas combustion furnace 1, drying chamber 2, first heat-exchanger rig 3, temperature sensor 4, control unit 5, valve 6, second heat-exchanger rig 17 and each pipeline.Waste gas combustion furnace 1 has self circulation heat exchange device 7.Drying chamber 2 is tunnel type drying room, and automobile is advanced and is subject to hot air dries from drying chamber.The waste gas that drying chamber 2 is discharged 12 enters the burner hearth entering waste gas combustion furnace after self circulation heat exchange device 7 carries out preheating again and burns by the road.The high-temperature gas that waste gas combustion furnace 1 is discharged is divided into two-way after valve 6 regulates.First via gas 8 enters multiple first heat-exchanger rig 3 by the road, gas in drying chamber 2 10 enters the first heat-exchanger rig 3 by the road, in heat-exchanger rig 3, the first via gas coming from waste gas combustion furnace 1 and the gas coming from drying chamber 2 carry out heat exchange, then 11 are got back to drying chamber 2 by the road by the gas heated in the first heat-exchanger rig 3.As seen from the figure, multiple first heat-exchanger rig 3 arranges along length direction (left and right directions in the figure) block form of drying chamber, and namely each first heat-exchanger rig 3 all has the pipeline 10 and pipeline 11 that are communicated with drying chamber 2 gas.First via gas 13 enters the second heat-exchanger rig 17 after discharging from the first heat-exchanger rig 3 by the road.Second heat-exchanger rig 17 extracts fresh air, the gas coming from pipeline 13 still has certain heat, heat exchange is carried out at the second heat-exchanger rig 17 place and fresh air, then the fresh air after preheating by the road 14, pipeline 15 arrives the two ends of drying chamber 2 respectively, for drying chamber 2 provides air curtain, this takes full advantage of the waste heat of first via gas.First via gas is discharged into ambient air through blast pipe 16 after the second heat-exchanger rig 17 is discharged.The second road gas through valve 69 enters self circulation heat exchange device 7 by the road, and the waste gas of discharging with drying chamber 2 carries out heat exchange, carries out preheating to waste gas.Certainly, the second road gas finally also will be discharged in ambient air through blast pipe 16 after a series of circulation.Temperature sensor 4 is arranged on blast pipe 16 place and apart from ground level 3.5m, invariably plane heat source disturbs.Temperature sensor 4 is connected with control unit 5, valve 6 is also connected with control unit 5, thus the temperature data that control unit 5 can collect according to temperature sensor 4 carrys out the aperture of by-pass valve control 6, the final ratio regulating the amount of the first via gas entering pipeline 8 and the second road gas entering pipeline 9.Adopt temperature sensor obtain temperature value and belong to this area conventional techniques means by control unit by-pass valve control aperture, be not described in detail herein.In the present embodiment, no longer be arranged on valve 6 place due to temperature sensor 4 but be arranged on blast pipe 16 place, therefore gathered temperature is the gas temperature be discharged in ambient air, the aperture of control valve 6 is carried out according to this temperature, control temperature can be set in temperature required scope (such as 180 DEG C), waste gas combustion furnace 1 is therefore, it is possible to carry out quantity of heat given up according to the heat of drying chamber 2 actual consumption, avoid thermal waste, economize energy, and make waste gas combustion furnace service life elongated, avoid long-term high-load operation.
Although the utility model is described in conjunction with above embodiment; but the utility model is not defined to above-described embodiment; those of ordinary skill in the art easily can carry out equivalence to it and replace and modification, but do not leave the protection domain of claim of the present utility model.
