To the inside for putting acid tube 31, the inside of receiving flask 35 is eventually flowed under gravity, prevents excessive germanium tetrachloride from spraying
The inside of leaching tower is hydrolyzed into germanium dioxide, has reached anticlogging purpose, opens water pump, water pump can be in spray tower bottom alkali pond
Lye pump to solution distribution grid 20, then the top of hold-down grid 19 is sprayed onto by nozzle, lye is flowed to along through-hole 15
The inside of packing layer 18, exhaust gas enter the inside of level-one spray column 1 from offgas duct 24, and the alkaline reaction in packing layer 18, instead
The lye that should be crossed flows back into the top of liquid collecting plate 6, and the alkali pond of 1 bottom of level-one spray column is returned to eventually by the inside of collector tube 9
Interior, the exhaust gas being cleaned enters the inside of two level spray column 2 by double purification by connecting tube 5, is discharged to eventually by exhaust pipe 3
In outside atmosphere, because 18 elder generation of packing layer of 1 bottom of level-one spray column and exhaust gas contact, 1 bottom of level-one spray column are filled out
The bed of material 18 can the phenomenon that first blocking, and when the 1 inside blocking of level-one spray column, user should rotatory sealing cap 29 be simultaneously immediately
It is made to be disconnected with screwed pipe 27, firmly pull draw ring 28 and drive safety pole 26 make its from right to left successively with barrier board
23rd, right side circular hole, middle part circular hole and left side circular hole are detached from grafting, and it is downward in the inside of sliding slot 7 under gravity to connect liquid plate 6
It slides, left side is filled plate 13 and is rotated counterclockwise for axis with cross bar 17, and right side filling plate 14 is rotated clockwise with cross bar 17 for axis, from
And the packing layer 18 of blocking is made to fall to the top for connecing liquid plate 6, reach the packing layer 18 that exhaust gas passes through 1 top of level-one spray column
Two level spray column 2 is simultaneously absorbed, safe and fast under the premise of manufacturing schedule is not influenced to dispose asking for spray column blocking
Topic terminates to carry out cleaning level-one spray column 1 by the tower body of maintenance window 4 or directly cutting level-one spray column 1 again until producing,
Achieve the purpose that having spray column blocks emergency measure.
In conclusion the germanium tetrachloride purification antifouling type can emergency operation lye spray column, by setting demisting
Plate 30 can liquefy germanium tetrachloride gaseous in exhaust gas and gaseous hydrochloric acid, reduce germanium tetrachloride and hydrochloric acid enters spray column,
The probability that spray column is blocked is reduced, the service life of lye inside spray column is increased, has reached anticlogging purpose, finally
Acid tube 31, ball valve 32, bellows 33, adapting pipe 34 and receiving flask 35 are put by setting, can be recycled liquefied by demisting plate 30
Germanium tetrachloride and hydrochloric acid have reached anticlogging purpose.
Also, by setting sliding slot 7, it can make to connect liquid plate 6 under gravity in the inside slide downward of sliding slot 7,
Again by setting supporting rod 16, cross bar 17, casing 11, force rod 12 and supporting rack 10, can make connecing 6 slide downward of liquid plate
Left side filling plate 13 is made to be rotated counterclockwise for axis with cross bar 17 simultaneously, right side filling plate 14 is rotated clockwise with cross bar 17 for axis,
The top of liquid plate 6 is connect so as to which the packing layer 18 for making blocking is fallen to, arrives the packing layer 18 that exhaust gas passes through 1 top of level-one spray column
Up to two level spray column 2 and absorbed, achieved the purpose that have spray column and blocked emergency measure, finally by setting jack 25,
Safety pole 26 and draw ring 28 can quickly make the packing layer 18 of 1 bottom of level-one spray column fall to the top for connecing liquid plate 6, reach
Has the purpose that spray column blocks emergency measure.
