Description

Technical Field

[0001] The invention relates to the technical field of ferric chloride production, in particular to ferric chloride production equipment. Background Art

[0002] Ferric chloride is a covalent inorganic compound that is a black-brown crystal. It is easily soluble in water and has strong water absorption. It can absorb moisture in the air and deliquesce. It is a very important iron salt. Currently, in the production process of ferric chloride, liquid chlorine is first vaporized to form chlorine gas, and then the chlorine gas is sent to a reaction tank to react with ferrous chloride to form ferric chloride. The excess chlorine in the reaction tank will be pumped into a recovery tank for recycling.

[0003] When the chlorine in the reaction tank is pumped into the recovery tank for recovery, the chlorine that has not fully reacted in the reaction tank will react when passing through the recovery pipe, thereby forming ferric chloride crystals that remain in the recovery pipe. Over a long period of time, excessive ferric chloride crystals will remain in the recovery pipe. Excessive ferric chloride crystals can easily cause blockage in the recovery pipe, affecting the speed of subsequent chlorine recovery. Moreover, if the ferric chloride crystals accumulate in the recovery pipe and are not cleaned and recycled, it will cause waste. Therefore, the ferric chloride crystals in the recovery pipe need to be cleaned and recycled.
