Tianjin Plate Heat Exchanger - Correct Shutdown Method for Fully Welded Plate Heat Exchanger
2020-07-26
The fully welded plate heat exchanger is a highly efficient heat exchanger made up of a series of metal plates stacked in a specific wavy shape. Thin rectangular channels are formed between the various plates, allowing for heat exchange through the plates. The fully welded plate heat exchanger is an ideal device for heat exchange between liquid-liquid and liquid-vapor.
Fully welded plate heat exchangerIt is a highly efficient heat exchanger made up of a series of metal plates stacked in a certain wavy shape. Thin rectangular channels are formed between the various plates, allowing for heat exchange through the plates.Fully welded plate heat exchangerIt is liquid—liquid, liquid—vapor is an ideal device for heat exchange. It has characteristics such as high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5times higher than that of tubular heat exchangers.The footprint is one-third of that of tubular heat exchangers, and the heat recovery rate can reach above.When using the equipment regularly, to ensure the service life of the device, it is not only important to use the equipment correctly, but also to perform another important task, which is to shut down correctly. Forboth service life and efficiency, correct shutdown is quite important. Let's understand it together.90%1. First, the pump must be stopped, and the power supply cut off;
2. If there is a drain valve installed on the pipeline, it should be opened;Fully welded plate heat exchanger3. During shutdown, the hot medium inlet valve must be slowly closed first, followed by the cold medium inlet valve. Then close the outlet valves of both media;Fully welded plate heat exchanger4. For high-temperature and corrosive media, efforts should be made to empty the system during shutdown to avoid injury to personnel and damage to equipment when opening the device.
The above content is a relevant introduction to the correct shutdown operation ofFully welded plate heat exchangerRegardless of whether it is a shutdown or normal use, correct operation is required. Providing more protection to the equipment will yield greater benefits in return.
二、如果管线上装有放空阀，应打开；
三、Fully welded plate heat exchanger停机，必须先缓慢地关闭热介质进口阀门，再关闭冷介质的进口阀门。之后关闭两介质的出口阀门；
四、对温度较高的介质及腐蚀性介质，应尽量使Fully welded plate heat exchanger停机放空，以免打开设备时伤害人和腐蚀设备。
以上内容就是对于Fully welded plate heat exchanger的正确停机工作的相关介绍。不管是停机也好，正常使用也好，都要求做到正确操作。给设备更多的保护，它才会回馈给我们更多的效益回报。
