[0023] In this embodiment, mounting seats 81 are provided at the top and bottom ends of the condenser 8, and a plurality of condensing tubes 82 are fixedly connected in a circular array between the two mounting seats 81. Air vents 83 are provided between two adjacent condensing tubes 82. An air supply pipe 84 is fixedly connected to one end of the bottom mounting seat 81 relative to the gas collecting bucket 7, and the water vapor is cooled by the condensing tube 82 to be converted into condensed water for recycling.

[0024] In this embodiment, the bottom mounting seat 81 is connected to the top pipeline of the gas collecting hopper 7 through the gas pipe 84, which facilitates the transportation of the rising water vapor to the condenser 8 through the gas pipe 84 to produce condensed water. An air intake check valve is fixedly installed at the connecting end of the gas collecting hopper 7 and the gas pipe 84 to prevent water vapor backflow.

[0025] In this embodiment, a liquid injection pipe 4 is fixedly connected to one end of the side wall of the tank body 1, and a liquid injection bucket 41 is fixedly connected to the end of the liquid injection pipe 4 away from the tank body 1, which is convenient for the discharge of electroplating wastewater.

The water vapor evaporated by the heating of the electroplating wastewater rises and is collected by the gas collecting bucket 7 and transported to the condenser 8 through the gas pipe 84. The water vapor passes through the activated carbon filter plate 9 to filter harmful particles. The purified water vapor passes through a plurality of condensing tubes 82 to produce condensed water, which is discharged from the vent 83 and falls from the water drop port 10 into the water collecting chamber 11 for collection by inertia, thereby realizing water recycling.
