The detachable flow guide mechanism is arranged, flow guide can be more effectively carried out through the lower ring type design, particularly, the lower flow guide cylinder ring can better cope with silicon splashing and other conditions, the control and capture effect on crystal growth is improved, when damaged, the lower flow guide cylinder ring can be conveniently and independently replaced, and the lower flow guide cylinder ring is convenient to replace. The maintenance cost is reduced, the resource waste condition is reduced, and the problems that after local damage, the overall replacement cost is high, and crystal growth bract falling is caused by inaccurate outer guide lower edge silicon sputtering reflective crystal growth capture are solved.
