U型式翅片换热器

U-shaped fin type heat exchanger

Abstract

一种U型式翅片换热器,包括多根翅片管、U型连管、进水接管和出汽接管;除了第一根翅片管的首端和最后一根翅片管的尾端,各根翅片管通过U型连管依次首尾连接,第一根翅片管的首端连接进水接管,最后一根翅片管的尾端连接出汽接管。本换热器采用了U型翅片管,其在顺酐生产中,放于反应生成的高温气体前端冷却部分,高温气体冷却器内部采用本换热器,对于水气换热防止结露累计、设备的腐蚀都有很好的控制;整个的设备寿命也延长3-5年;翅片管换热器的特点,造价低,材料非特殊材料,易采购,对于压力高的要求下,其制作成本明显降低很多,安装方便,可以进行拆装,是在气体换热段起到明显换热和防腐蚀的产品。
The utility model relates to a U-shaped fin type heat exchanger, which comprises a plurality of finned tubes, a U-shaped connecting pipe, a water inlet pipe and a steam outlet pipe; the finned tubes are sequentially connected with one another from the head to the tail by the U-shaped connecting pipe except the head end of the first finned tube and the tail end of the last finned tube, the head end of the first finned tube is connected with the water inlet pipe, and the tail end of the last finned tube is connected with the steam outlet pipe. The heat exchanger adopts the U-shaped finned tubes; the heat exchanger is placed at the cooling part at the front end of the high temperature gas generated in reaction during the production of maleic anhydride; and the heat exchanger is utilized in a high temperature gas cooler and has good control of preventing the accumulation of moisture condensation and the corrosion of equipment owing to heat exchange of water and steam, and the service life of the whole equipment can be prolonged 3 to 5 years. The heat exchanger with the finned tubes has the characteristics that the manufacturing cost is low, no special materials are needed, the materials are easy to purchase, the manufacturing cost is obviously reduced based on the requirement of high pressure, the installation is convenient, and the heat exchanger can be disassembled and assembled, therefore, the heat exchanger is the product which can realize heat exchange and corrosion prevention in the gas heat exchange phase.
