The Hua Tanei cold whirlwind of mixed gas radial impact, and being mixed with the cold whirlwind so that material gas obtain secondary cooling and
Sublimate, more than 99% material gas is become solid phase powder, and particle size uniformity is higher；Wherein, including once, secondary cooling,
So that the speed of sublimating of material pneumatic.
Relative to prior art, what the present invention had has the technical effect that：（1）When the device of sublimating of the present invention works, compression
Gas carries material gas and enters each mixed gas entrance, and into the moment refrigeration sublimated in tower, obtains material gas
Once cool down and play a part of uniform pre- cold material gas, and can obtain a small amount of thing of sublimating；（2）In the present invention, the threeway
Second entrance axial line it is vertical with the axial line of first entrance, the first entrance of the threeway and corresponding mixed gas entrance
It is coaxially disposed, material gas is sucked to form mixed airflow by compressed gas while mixed gas entrance is rapidly entered.Together
When, the mixed gas sublimated in tower is entered from each mixed gas entrance and is mixed with the cold whirlwind from spiral case so that material gas
Obtain secondary cooling and realize secondary sublimate；Wherein, because each mixed gas entrance is radially uniform relative to cold whirlwind so that
Mixed gas is radially impacted to the eddy flow of cold whirlwind, further such that material gas fully, uniformly mixes with cold whirlwind, and
So that the particle size uniformity for generation of sublimating is preferable；In this way, relative to prior art, the material gas of the present embodiment is sublimated
Rate up to more than 99%, and speed of sublimating add it is fast again.（3）Cold whirlwind in the present invention rotates from top to bottom along inner wall of tower of sublimating,
It can prevent material from gluing wall.（4）The present invention realizes sprayed feed using threeway, and can be big by adjusting the pressure of compressed gas respectively
Small, material gas throughput, the particle diameter for material of sublimating is controlled, so as to obtain the particle of required particle diameter.（5）The present invention is implemented
When, according to thermal balance, required cold wind air quantity, and the wind speed 0.1-0.2m/s that control is sublimated in tower can be accurately calculated, to extend
Sublimate the residence time of material of tower, on the one hand fully sublimated beneficial to material, on the other hand, relatively low wind speed is beneficial to material sedimentation,
