摘要
本文介绍的工程项目在于研发一种激光技术来清除大面积海域和其他水面存在的油膜污染物。针对海面严重污染问题,研究了基于喷气发动机的可移动气动CO2激光器(100～250kW)的设计方案及其在清除水面污染时的工程实现。提出的技术方案意在有效弥补传统的海面油膜处理方法只可处理块状油层而无法消除100μm厚油膜的弊病。文中介绍了可移动气动CO2激光器的设计机理,研究了可执行该项工作的不同类型的激光器,证明了选用可移动气动CO2激光器执行该项工作的合理性。考虑了激光器系统的供气方案,选择了高质量的喷气发动机作气动CO2激光器的动力设备并设置了该设备工作时需要的容量。最后,描述了该激光系统气动液压设备的设计方案,给出了相关设备、油箱、和操作控制单元的结构。目前,作者已经完成了用于处理水面油膜的气动CO2激光器的概念设计,并制备了相应的激光系统。另外,研制了气动CO2激光器系统的工作平台,通过用激光束扫描石油膜覆盖的水面,实验验证了利用该系统收集油膜和令油膜有效燃烧的可行性。
The purpose of the project presented in the paper is to develop a laser technology to clean large areas of seas and other water surfaces from oil film contamination. It mainly aims development of technological scheme and engineering design of jet engine based mobile Gas Dynamic Lasers （GDLs） （100 -- 250 kW） intended to solve this important problem of environment protection. This method and laser system proposed are expected to complement other traditional methods, which usually more successfully treat bulk layer oil pollution but do not matchto eliminate up to 100μm oil films. In this paper, the basic design concept of a mobile gas dynamic C02 laser is introduced, and the possibility of using various types of lasers for solution of required tasks is considered and the selection of GDL is justified. Then, the possible schemes of organization of air supply in the laser installation are consid- ered, and the jet engines are selected as the high quality power unit of GDL installation. The necessa ry volume of the selected jet engine adaptation/modification experimental works is presented. Finally, the paper describes the design concept of GDL and the pneumohydraulic schematics, and gives struc- tures of the related equipment, fuel tanks and operation control units. Now, the author has completed the conceptual analysis of GDL installation for disposal of petroleum films from a water surface, the basic capability of development of such installation is shown. The basic characteristics of the system are discussed and the schematic and design solutions of basic installation are presented. Furthermore, the GDL platform has been developed and some demonstration operations with scanning beam over water surface covered with petroleum film are carried out. The experiments confirm the effective gath- ering and burning of oil films on the water surfaces by proposed system.
