This invention relates to the field of
ammonia separation technology and discloses an automatic
air separation device, comprising: a separation tank, a low-temperature coil vertically arranged inside the separation tank, and multiple sets of
ammonia droplet limiting mechanisms spaced axially along the upper part of the low-temperature coil, which divide the upper part of the low-temperature coil into multiple independent condensation chambers; the
ammonia droplet limiting mechanism includes an ammonia droplet
elimination disc, a turbulence tree, and an ammonia bead shaking
assembly, the ammonia droplet
elimination disc being composed of two parallel braided discs, both of which are made of stainless steel fine tubes woven in a warp and weft pattern to form a grid structure, and the two braided discs are connected to the interior of the low-temperature coil to form a low-temperature medium circulation channel; this invention, by setting a combination structure of turbulence tree and braided disc, achieves two ammonia droplet captures during the rising process of the
mixed gas: "condensation on the surface of turbulence tree branches" and "condensation on the braided disc grid," significantly improving the capture efficiency of tiny ammonia droplets and preventing droplets from being carried out by the
airflow.
