摘要 柴油发电机是一种把燃油的化学能转化为电能的机电一体化设备。在现代化程度日益提高的今天，特别是随着计算机网络以及通讯事业的蓬勃发展，设备对于电力供应可靠性的要求也日益增强，这样就使得柴油发电机有了广阔的发展空间。但是柴油发电机在为人们提供便利的同时，也因为机组自身存在的噪声、排放等问题影响着我们的生存环境人们的工作和生活。随着人们对环境要求的逐渐提高，如何解决并克服上述问题就成为柴油发电机应用和发展的关键对发电机排出的尾气黑烟，目前的常规做法是采用旋流板水洗喷淋法’s chemical energy into electric energy. In the increasingly modern today, especially with the vigorous development of computer’s network and communication career, the reliability of the electric power accommodation for the equipment needed to be improved. It will come into a truth that diesel generator will win an extensive application in the market. Meanwhile, the generator’s exhaust gas and noise destroy our environment and bother our life and work. With the high demand of the environment, how to solve the problems has become the key for the diesel generator’s application and development. This paper is mostly designed for the diesel generator’s room aeration、noise control、flue gas’ purification and recycle of the remnant heat. Combining the present projects, the conventional mean of the generator exhaust gas’ purification is cyclonic spray scrubber. And this project has improved the conventional cyclonic spray techniques, including the optimization of the tower plate’s arrangement and spiral angle. And it introduces the non-plugging spray nozzle instead of the atomization nozzle, which is specially designed for the project. These improvements solve the key technical problems such as easy blocking and great loss of spiral flow plate resistance. Besides, this project presents a new point, which is recycling the exhaust gas heat by using the heat exchanger.
