Built-in detachable filter for plate heat exchanger

The invention relates to a built-in detachable filter for a plate heat exchanger, which comprises a front built-in filter, a rear built-in filter and a detachable blind plate, and the front built-in filter and the rear built-in filter are mounted in a seawater inlet channel of the plate heat exchanger and are sealed by a seawater pipeline and the detachable blind plate. The built-in detachable filter for the plate heat exchanger is adopted, so that the seawater side of the marine plate heat exchanger can realize a filtering function; by adopting the filter for the built-in detachable plate heat exchanger, the space of the seawater filter can be saved, the optimization is completed in the equipment, and the size is reduced. 本发明涉及一种可内置拆装的板式换热器用滤器，包括前内置滤器、后内置滤器、拆装盲板，所述前内置滤器、后内置滤器安装于板式换热器海水进口通道内，并由海水管道及拆装盲板密封。采用可内置拆装的板式换热器用滤器可让船用板式换热器海水侧实现过滤的功能；采用可内置拆装的板式换热器用滤器可将海水滤器空间节省，优化在设备内部完成，减少尺寸。
