The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing, the utility model is further described, the content that embodiment is mentioned not is to restriction of the present utility model.Referring to Fig. 1 to Fig. 4, below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment one.
according to shown in Figure 1, in embodiment one, the heat-exchange system of a kind of waste heat recovery that the utility model provides, the heat exchanger 2 that comprises frame 1 and be arranged at frame 1, pressure fan 3, oven body 5 and exhaust blower 6, one end of described pressure fan 3 is connected with heat exchanger 2, its other end is connected with oven body 5, described exhaust blower 6 is positioned at the outside of frame 1, described oven body 5 is provided with hot-blast spray nozzle 7, this heat-exchange system also includes residual-heat exchanger 8, described residual-heat exchanger 8 is provided with the first air inlet, the second air inlet, the first air outlet and the second air outlet, the first air inlet is communicated with outside, described the second air inlet is connected with the exhaust outlet of oven body 5, described the first air outlet is connected with heat exchanger 2, described the second air outlet is connected with exhaust blower 6.Wherein, be provided with air supply duct 4 between described pressure fan 3 and oven body 5, the two ends of described air supply duct 4 are connected with pressure fan 3, oven body 5 respectively.
In the present embodiment one, described residual-heat exchanger 8 and heat exchanger 2 all are located at the top of frame 1.The heat energy of heat exchanger 2 comes from external combustor, the hot cigarette that combustor produces flows at the inner-walls of duct of heat exchanger 2, during natural airflow over-heat-exchanger 2, natural wind is heated to form hot blast because of heat exchange, hot blast is delivered to oven body 5 inside by pressure fan 3 by ventilation shaft 4, carries out heat treated for the strip 9 that is contained on conveying roller through hot-blast spray nozzle 7.The volatilization because the resin on strip 9 surfaces is heated, hot-air becomes the mist of chemical substances such as containing plasticizer and solvent, and the temperature of this mist is still very high.Mist is introduced residual-heat exchanger 8 as heating source by exhaust blower 6, can carry out preheating to replenishing the natural wind that enters.Make the natural wind by residual-heat exchanger 8 reach certain temperature before arriving heat exchanger 2.Heat exchanger 2 just need not consume the more energy like this, reduces the energy consumption of heat exchanger 2, reaches energy-saving effect.
The hot air temperature that for example enters oven body need to reach 200 ℃, if there is no this residual-heat exchanger 8, heat exchanger 2 need to be heated to 200 ℃ to air from room temperature 25o, and natural wind need heat 175 ℃.When natural wind arrived heat exchanger 2 through residual-heat exchanger 8, temperature may reach 100 ℃, like this 2 need of heat exchanger make natural wind heat 100 ℃ just much of that.
