Novel energy dissipation and pressure reduction device of MBR plate-type membrane cleaning system

The utility model discloses a novel energy dissipation and pressure reduction device of an MBR plate type membrane cleaning system. The device comprises an inner cavity and an outer cavity, a water inlet is formed in the side surface of the outer cavity; a water outlet is formed in the bottom surface of the outer cavity; the water inlet is connected with an energy dissipation device arranged in the outer cavity, the energy dissipation device comprises an inner cavity formed in the outer cavity, the water inlet is communicated with the inner space of the inner cavity, the diameter of the innercavity is larger than that of the water inlet, the inner space of the inner cavity is communicated with an air vent formed in the top of the outer cavity, and a plurality of overflowing holes are formed in the inner cavity. The energy dissipation device has a simple structure, is convenient to use, can effectively dissipate energy of liquid for cleaning the MBR plate-type membrane, reduces the damage risk of the MBR plate
