Wuhan Dongfeng Peugeot Citroen Automobile Plant Waste Heat Recovery coating production line Dongfeng Peugeot Citroen Automobile Co., Ltd., Dongfeng Peugeot Citroen Automobile and automobile production joint venture operating company headquartered in Wuhan. Currently, energy saving has become corporate and social attention. Wuhan Plant is also actively involved in energy saving initiative. The company along with a large amount of heat emission in the paint production process, this part of the heat has not been fully utilized, Shanghai Nanyang heat pipe Boiler Manufacturing Co., Ltd. construction by oven heat recovery project has been successfully put into October 7, 2013 use. Up to now, due to the successful operation of the waste heat recovery equipment, has led to Plant boiler room of normal production time to 20 hours a day, the original opening time is reduced to only open 1-2 hours a day, making the boiler room daily natural gas consumption increased from more than 10,000 reduced to more than 2000 cubic cubic achieved remarkable energy savings. Waste heat recovery project is the use of three high-efficiency heat pipe heat recovery device, the paint shop near the chimney oven to 200 ° C high temperature flue gas heat absorption, it dropped to around 100 ° C emissions, absorption The heat is used to pre-heat treatment, such as degreasing phosphating tank to be heated so that the bath temperature is required to meet the production process conditions, so as to achieve the purpose of recycling waste heat. And originally used to bath heating boiler room in the waste heat recovery device applications, then as a secondary back-up heat source, open in the heat recovery equipment insufficient heating, thus reducing the consumption of natural gas boiler room.
