The preparation feed liquid flows into a feed liquid flow channel (8) through a feed liquid pipe (7) and flows into a guide cylinder (3) through a liquid outlet, and the preparation feed liquid flows along the upper end of the guide cylinder (3) under the driving of a propeller (6);

The preparation feed liquid flows out from the upper end of the guide cylinder (3) and flows downwards between the guide cylinder (3) and the cylinder baffle (2);

and part of the prepared feed liquid flows back to the guide cylinder (3) from the lower end of the guide cylinder (3) to circularly flow, and triazole sodium particles gradually grow in the circularly flow to obtain triazole sodium crystals with uniform particles.
