摘要
复合型蒸发式空冷器是近几年研发的新型高效冷换设备,具有结构紧凑、投资低、防垢防"白雾"、传热效率高等诸多优点。复合空冷的设备及管道布置除要满足空冷器的一般规定外,有其自身特点。通过与普通空冷对比,从占地面积角度介绍其平面布置,提出了"背靠背、面靠面"的设备布置形式;从两相流管道布置、入口管道支撑及管道应力计算方面介绍其管道布置,提出了复合空冷管嘴处不存在附加位移,可通过自然补偿来降低管嘴受力,为复合型蒸发式空冷器的设备及管道布置提供参考。
Compound evaporative air cooler is a new kind of effective heat exchange equipment developed in recent years. It has many advantages, such as compact construction, low investment, scale prevention, ‘white mist' prevention and high heat transfer efficiency. The equipment layout and piping arrangement of compound evaporative air cooler has its own requirements apart from meeting the general provisions of air cooler. Compared to ordinary air cooler, and with the respect of occupying area, the equipment layout of ‘back to back, side by side' was proposed. The piping arrangement was then introduced from respects of the two-phase flow, support of inlet pipe and pipe stress calculation. It was conclude that there is no additional displacement existed in the nozzles in compound evaporative air cooler, and the nozzle stress can be reduced from self-compensation of pipe. What presented herein can be referenced in equipment layout and piping arrangement for compound evaporative air cooler.
