Component be connected using U-bolt 65 with the supportive grid 64 of tower tray 6, so, orifice plate will not be made inclined when orifice plate expanded by heating
Move, larger thermal stress will not be caused to structure, while also playing good supporting role to tower tray.
Embodiment two
This practical hydrogen chloride drier, using vertical multi-sectional fluid bed, is made up of, tower tray is by spectacle plate ten sections of tower trays
It is spliced, is fixed on grid.Single air compartment positioned at fluidized-bed bottom entirely can provide fluidizing gas by drier.By working as
When hydrogen chloride gas rises through the tower tray being made up of orifice plate, the free zone above the orifice plate is just into the wind of next tower tray
Room.Bed material is delivered to next tower tray by down-comer (each tower tray constituted through abacus) from a tower tray.It is all
Material is all guided to downwards fluid bed lower end by down-comer, but tower tray 3 makes an exception, and it is also equipped with gill type dispenser, can be by material
It is ejected on fluid bed.Baffle plate is distributed on every section of tower tray, the residence time for adjusting pellet.In tower tray 1 and tower tray 3
Bottom is disposed with steam pipe coil, for energy compensating.
This practical hydrogen chloride drying tower proposes new fluidizing agent, using the hydrogen chloride gas of heating, removes material
In moisture, concrete example can apply to be dehydrated magnesium chloride, it is suppressed that the hydrolysis of magnesium chloride, reduce again upper one
The basic magnesium chloride that workshop section's hydrolysis of magnesium chloride is produced.Hydrogen chloride is dried shell and manufactured using the chrome-nickel of various thickness, both
Corrosive fluidizing agent can be utilized, poisonous and hazardous material can also be produced.
The alkali formula for the high content that the aerial hydrolysis of bischofite in the dehydration electrolytic magnesium technique of bischofite is produced
Magnesium chloride so that electrolysis technique can not be used after dewatering bischofite, bischofite magnesium technique can not be realized.This is practical
Hydrogen chloride drier is combined with hydrochloric acid deep analysis technique, and the hydrogen chloride gas of the high concentration gone out using hydrochloric acid deep analysis can
So that by dewatering bischofite to 0.03%, basic magnesium chloride controls 0.2%, anhydrous magnesium chloride is wanted considerably beyond electrolysis
