High-temperature flue gas utilizing system of automobile coating drying chamber and utilizing technology

The invention discloses a high-temperature flue gas utilizing system of an automobile coating drying chamber. The high-temperature flue gas utilizing system comprises the drying chamber, a heat supply system, a fresh air heat exchange system and an air curtain system. The heat supply system comprises a heat supply chamber, a combustor and a heat exchanger. The combustor and the heat exchanger are connected in parallel to be arranged in the heat supply chamber. The fresh air heat exchange system comprises a heat exchange chamber, a heat supply combustor, a heat supply heat exchanger, a flue gas heat exchanger, a heat exchange draught fan and a heat exchange filter. The heat supply combustor and the heat supply heat exchanger are connected in parallel to be arranged in the heat exchange chamber. The air curtain system is arranged on the upper sides of the two ends of the drying chamber and comprises air ports, pressurizing chambers and an air curtain pipeline. The air curtain pipeline is communicated with an air outlet. The pressurizing chambers are arranged at the two ends of the air curtain pipeline, and the air ports are formed in the lower sides of the pressurizing chambers. The high-temperature flue gas utilizing system has the beneficial effects that the energy saving and emission reducing effects are obvious, cost is controlled, and economic benefits are obviously improved.
