Marine heat exchange system capable of bi-directionally filtering seawater

The utility model relates to a marine heat exchange system capable of bi-directionally filtering seawater, which comprises control valve banks, a seawater filter, a heat exchanger, a seawater pipeline and a pressure gauge, the control valve banks are arranged on an inlet and an outlet of the heat exchanger, two control valves are connected in series to form a group, and the two control valve banks are respectively connected with the seawater inlet and the seawater outlet of the heat exchanger. Meanwhile, a pressure gauge is arranged on the seawater pipeline; the two seawater filters are respectively arranged on a water inlet and a water outlet of the heat exchanger. By adopting the marine heat exchange system capable of filtering seawater in two directions, the seawater side filter of the marine heat exchanger can be cleaned without shutdown after the valve group is switched once. By adopting the marine heat exchange system capable of filtering seawater in two directions, the work of cleaning the seawater fil
