Described wash cycle pipe is also communicated with puts acid tube.
Under described circulation fluid, on liquid pipe, be also connected with discharging tube.
Described scrubbing tower middle and upper part is provided with water inlet.
Between described each wash cycle pipe by valve control.
The beneficial effects of the utility model are:
Compared with prior art, the utility model adopts Venturi scrubber and scrubbing tower to combine, by increase wire mesh demister, sieve plate and annular washing nozzle in tower, after adopting twice washing, remove liquid phase part through wire mesh demister, detersive efficiency is high, the tail gas fluorinated volume of discharging after washing is lower, little to environmental disruption, has good social benefit; After processing, directly fluorinated tail gas is converted into fluosilicic acid simultaneously, can be used as the raw material of other products, there is good economic benefit; Adopt industry water to wash, washing cost is low.The utility model is simple in structure, and cost of investment is few, and floor space is little, and operating cost is low.Can be in fluorinated tail gas technical field wide popularization and application.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: the fluorine-containing gas phase pipe of 1-, 2-Venturi scrubber, 3-wash cycle pipe, 4-cleaning circulation pump, 5-air door, 6-air-introduced machine, 7-wire mesh demister, 8-water inlet, 9-annular washing nozzle, 10-sieve plate, 11-scrubbing tower, 12-is put acid tube, 13-discharging tube, liquid pipe under 14-circulation fluid.
Detailed description of the invention
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of fluorinated tail gas wash mill described in the utility model, comprise fluorine-containing gas phase pipe 1, Venturi scrubber 2, wash cycle pipe 3, cleaning circulation pump 4 and scrubbing tower 11, described Venturi scrubber 2 upper ends are communicated with fluorinated tail gas pipe 1, throat is communicated with wash cycle pipe 3, bottom is communicated with scrubbing tower 11 along scrubbing tower 11 tangential directions, and the outlet of described cleaning circulation pump 4 is communicated with wash cycle pipe 3, and import is connected with the bottom of scrubbing tower 11 by liquid pipe 14 under circulation fluid.
Described scrubbing tower 11 inside are separately installed with sieve plate 10, annular washing nozzle 9 and wire mesh demister 7 from bottom to up.
On the top gas phase pipe of described scrubbing tower 11, be connected with air door 5, be connected with air-introduced machine 6 in the outlet of air door 5.Adopt the technical program, wash mill is in running, and the air quantity of fluoro-gas can regulate by air door 5, and is undertaken emptying by air-introduced machine 6.
Described wash cycle pipe 3 is divided into two, and one is connected with Venturi scrubber 2, and another root is connected with the circulation cleaning shower nozzle 9 of scrubbing tower 11 middle and upper parts.
