Through the arrangement of the liquid outlet interface 7, the external liquid outlet pipeline can be connected to recover the condensed liquid.

[0031] Working principle:

[0032] In use, the hot exhaust air from the exhaust air pipeline of the machine table of the glue coating and developing machine enters the space A 001 in the box 1 through the air inlet of the box 1, passes through the air passing holes 201 on the partition plate 2 and enters the space B 002, and then is discharged to the main exhaust air pipeline of the factory from the air outlet of the box 1; when the hot exhaust air passes through the air passing holes 201 with small diameters, the pressure changes, and in addition, the temperature of the partition plate 2 is effectively reduced by the cooling liquid through the pipe 3, so that when the hot exhaust air passes through the partition plate 2, the simultaneous changes of the temperature difference and the pressure difference of the gas accelerate the condensation of the liquid molecules carried in the hot exhaust air, so that the liquid molecules are first dropped to the bottom surface of the inner cavity of the box 1 and discharged through the liquid discharge port, thereby effectively avoiding the condensation of a large amount of liquid molecules in the main exhaust air pipeline of the factory, and avoiding the problem that the condensed liquid flows back to the rear end of the machine table and accumulates at the rear end of the machine table.
