firstly, after the elemental mercury and the chlorine gas are combusted, the reacted mercuric chloride needs to be output to the next processing procedure through a guide pipe, but since the reaction retort is too far away from the next processing procedure, the vaporized mercuric chloride is often condensed on the guide pipe, and the conveying efficiency is low.

Secondly, when the reaction is carried out by using a guide pipe, the condensed mercury chloride flows back to the reaction retort again, so that the reacted mercury chloride cannot be rapidly carried out, and the reaction rate in the reaction retort is influenced.

Thirdly, when the duct is used for conveying, the airflow power source is used for providing power for the vaporized mercury chloride, so that the time for the mercury chloride to be in the duct is increased, more mercury chloride is condensed on the inner wall of the duct, and the production efficiency is low;

from the above, it is obvious that the prior art has inconvenience and disadvantages in practical use, so that improvement is needed.
