Because the density difference of gas-liquid, on the liquid drop in the air was got rid of the pipe wall of defogging pipe at the spiral in-process, liquid discharge mechanism through the pipe wall discharged defogging pipe, made liquid flow outside defogging pipe to discharge rapidly through the liquid outlet in the defogging unit box, fundamentally avoided the liquid to flow the sputtering that leads to in defogging pipe and the secondary that arouses because of the sputtering to smuggle the problem secretly.

The elongated liquid discharge gaps are uniformly distributed at the air outlet end of the demisting pipe, so that the collected liquid can be rapidly and uniformly discharged.

Also can distribute liquid discharge gap is crisscross for the projected area of liquid discharge gap on the defogging pipe bottom surface is big, and liquid discharge effect is better, and when the axis direction of liquid discharge gap and defogging pipe was perpendicular, the projected area of liquid discharge gap on the defogging pipe bottom surface was the biggest, and the flowing back effect is best.

For the gas with larger humidity, the collected liquid can be more, the liquid discharge mechanism can be designed into a round hole or a square hole, and the round hole or the square hole has larger hole ratio, so that the liquid can be discharged in time under the condition of more liquid.

In order to improve defogging efficiency, can install a plurality of defogging pipes in the defogging unit box, consider that the qualification rate of defogging unit box processing is high, manufacturing cost reduces, and defogging pipe quantity is 2, 4 or 6 for the optimum. In order to further improve the demisting efficiency, a plurality of demisting unit boxes can be arranged on the liquid collecting pipe.

Considering later convenient dismantlement, defogging unit backup pad and defogging unit box can pass through bolted connection.
