Description
Technical field
The utility model is related to a kind of absorption tower, more particularly to a kind of fluorine gas absorption tower.
Background technology
In Chemical Manufacture, especially in the process of production phosphoric acid, peroxophosphoric acid hydrogen calcium, double superhosphate or double superphosphate
In, it is needed by sulfuric acid or decomposing phosphorite by using nitric acid, so that a part of fluorine (F) in phosphorus ore is with ocratation (SiF4)
Form effusion, in this decomposable process, up to 30% -50%, gas fluorinated volume reaches 15-25g/m to the effusion rate of fluorine
3, this can cause more serious injury to surrounding environment and staff.Therefore, in actual production process, generally will
The fluoro-gas of generation carries out absorption treatment, can both play a part of environmental protection, while can also be made the fluorine of absorption containing
Fluorine product.At present to the absorption treatment of fluoro-gas, generally by the way of hollow-spraying-tower washing absorption, but this absorption side
In formula, easily there is situation about blocking for the shower nozzle and separating tube that spray in practical operation, and spray insufficient and purification
Not exclusively, the absorptivity of fluoro-gas is reduced, while frequently cleaning work, has been greatly reduced the work of the absorption pattern
Efficiency.
The content of the invention
The purpose of this utility model is, there is provided a kind of fluorine gas absorption tower, the fluorine gas absorption tower have spray fully, it is net
Change complete, the absorptivity of enhancing fluorine gas.
The technical solution of the utility model：A kind of fluorine gas absorption tower, including fluorine gas pretreatment unit, fluorine gas pretreatment unit
Arrival end be connected with wireway, the port of export is arranged in absorption tower, and the exhaust outlet on absorption tower is filled by discharge duct with purification
The arrival end connection put, is provided with blower fan in discharge duct.
Foregoing fluorine gas absorption tower, the absorption tower is internally provided with collecting tank, spiral board, demisting plate and filter.
Foregoing fluorine gas absorption tower, the demisting plate and filter are provided with atomizer.
Flow-stopping plate has been shifted to install up and down in foregoing fluorine gas absorption tower, the purifier.
Foregoing fluorine gas absorption tower, the fluorine gas pretreatment unit side wall is provided with liquid injection pipe, liquid injection pipe and annular point liquid
Pipe is connected, and nozzle is provided with the madial wall of annular separating tube, and guiding gutter is provided with the bottom inside wall of annular separating tube.
The beneficial effects of the utility model：The utility model is by fluorine gas pretreatment unit and the rotation being arranged in absorption tower
Stream plate, demisting plate, atomizer and filter, improve the absorptivity and purifying rate of fluorine gas；Dislocation sets up and down in purifier
Be equipped with flow-stopping plate, more further improve the purifying rate of fluorine gas, on fluorine gas pretreatment unit set blast pipe and annular point
The nozzle set on the madial wall of liquid pipe, guiding gutter is provided with annular separating tube bottom inside wall.Which solves spray
Easily there is situation about blocking in head and separating tube, and improve the absorptivity of fluorine gas, reduce the working time of cleaning, improve and absorb
The operating efficiency of fluorine gas.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
A kind of fluorine gas absorption tower, is constituted as depicted in figs. 1 and 2, including fluorine gas pretreatment unit 1, fluorine gas pretreatment unit 1
Arrival end be connected with wireway 2, the port of export is arranged in absorption tower 3, the exhaust outlet on absorption tower 3 by discharge duct 4 with it is net
6 arrival end connection is put in makeup, and blower fan 5 is provided with discharge duct 4.
The absorption tower 3 is internally provided with collecting tank 31, spiral board 32, demisting plate 33 and filter 35.
The demisting plate 33 and filter 35 are provided with atomizer 34.
Flow-stopping plate 7 has been shifted to install up and down in the purifier 6.
The side wall of the fluorine gas pretreatment unit 1 is provided with liquid injection pipe 11, and liquid injection pipe 11 is connected with annular separating tube 12, annular
Nozzle 13 is provided with the madial wall of separating tube 12, guiding gutter 14 is provided with the bottom inside wall of annular separating tube 12.
Operation principle of the present utility model is：The sidepiece liquid injection pipe 11 of fluorine gas pretreatment unit 1 arranges parenteral solution by annular
The flow nozzle 13 of tracheae 2, parenteral solution is sufficiently mixed reaction, ring by atomizer 13 to the fluorine gas in fluorine gas pretreatment unit 1
The guiding gutter 14 set on the bottom inside wall of shape separating tube 12 flows into reaction solution and compounding substances in collecting tank 31, after reaction
Fluoro-gas pass sequentially through spiral board 32 in absorption tower, demisting plate 33 and filter 35 pass through discharge duct 4 again after filtering
Entered in air after into purifier 6, so as to reach fluorine removal and reduce the purpose of air pollution.Shower nozzle is solved easily to occur
The situation of blocking, improves the absorptivity of fluorine gas, reduces the working time of cleaning, improves the operating efficiency for absorbing fluorine gas.
