Description
Technical field
The utility model is related to a kind of wash mill, more particularly to a kind of absorption tower entrance silicon fluoride gas cleaning unit.
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 is escaped, and in this decomposable process, up to 30%-50%, gas fluorinated volume reaches 15-25g/m 3 to the effusion rate of fluorine, this
More serious injury can be caused to surrounding environment and staff.Therefore, in actual production process, generally by generation
Fluoro-gas carries out absorption treatment, can both play a part of environmental protection, while also the fluorine of absorption can be made into fluorine-containing product.
At present to the absorption treatment of fluoro-gas, generally by the way of hollow-spraying-tower washing absorption, but in this absorption pattern,
Easily occur situation about blocking during practical operation for the shower nozzle for spraying, the absorptivity of fluoro-gas is reduced, while frequently
Cleaning work, has been greatly reduced the operating efficiency of the absorption pattern.
Utility model content
The purpose of this utility model is, there is provided a kind of absorption tower entrance silicon fluoride gas cleaning unit.The absorption tower
Entrance silicon fluoride gas cleaning unit has the characteristics of absorption efficiency is high, and shower nozzle is not easily blocked.
The technical solution of the utility model：A kind of absorption tower entrance silicon fluoride gas cleaning unit, including fluorine gas pretreatment
Device, fluorine gas pretreatment unit is arranged on absorption tower, and the port of export of fluorine gas pretreatment unit is arranged in absorption tower, and fluorine gas is pre-
The arrival end of processing unit is connected with wireway, and fluorine gas pretreatment unit side wall is provided with to be surveyed in liquid injection pipe, liquid injection pipe and is provided with
Separating tube, is provided with nozzle on separating tube, liquid injection pipe is connected by pipeline with hydrops pond, and hydrops pond is circulated by pipeline with cooling
Pump is connected.
Foregoing absorption tower entrance silicon fluoride gas cleaning unit, the folder between the fluorine gas pretreatment unit and absorption tower
Angle is 15-45 °.
Foregoing absorption tower entrance silicon fluoride gas cleaning unit, the nozzle is distributed in the both sides up and down of separating tube.
The beneficial effects of the utility model：The utility model is by the wireway set on fluorine gas pretreatment unit and setting
In the nozzle of the upper and lower both sides of separating tube, easily occur situation about blocking which solves shower nozzle, improve the absorption of fluorine gas
Rate, reduces the working time of cleaning, improves the operating efficiency for absorbing fluorine gas.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Mark in accompanying drawing for：1- fluorine gas pretreatment units, 11- liquid injection pipes, 12- separating tubes, 13- nozzles, 2- wireways,
3- hydrops pond, 4- coolant circulation pumps, 5- absorption towers.
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 absorption tower entrance silicon fluoride gas cleaning unit, is constituted as shown in figure 1, including fluorine gas pretreatment unit 1, fluorine
Gas pretreatment unit 1 is arranged on absorption tower 5, and the port of export of fluorine gas pretreatment unit 1 is arranged in absorption tower 5, and fluorine gas is located in advance
The arrival end for managing device 1 is connected with wireway 2, and the side wall of fluorine gas pretreatment unit 1 is provided with to be surveyed in liquid injection pipe 11, liquid injection pipe 11 and sets
Separating tube 12 is equipped with, nozzle 13 is provided with separating tube 12, liquid injection pipe 11 is connected by pipeline with hydrops pond 3, and hydrops pond 3 passes through
Pipeline is connected with coolant circulation pump 4.
Angle between the fluorine gas pretreatment unit 1 and absorption tower 5 is 15-45 °.
The nozzle 13 is distributed in the both sides up and down of separating tube 12.
Operation principle of the present utility model is：Production production phosphoric acid, peroxophosphoric acid hydrogen calcium, double superhosphate or double superphosphate
The gas that generates in post synthesis of raw material enter in wireway 2, then absorption tower 5 is entered by the treatment of fluorine gas pretreatment unit 1
Interior, the port of export of fluorine gas pretreatment unit 1 is arranged in absorption tower 5, and is 15-45 ° with the angle between absorption tower 5, is prevented
Absorbing liquid is poured in down a chimney in wireway 2, and the arrival end of fluorine gas pretreatment unit 1 is connected with wireway 2, the side of fluorine gas pretreatment unit 1
, by parenteral solution by the flow nozzle 13 of wireway 2, in the presence of pump, positioned at separating tube, about 12 both sides for liquid injection pipe 11 on wall
Nozzle 13 sprays parenteral solution, with fluorine gas hybrid reaction, so as to reach the purpose of fluorine removal, reduces air pollution.Hydrops pond 3 is by cold
But the constant temperature parenteral solution needed for the effect of circulating pump 4 is supplied to liquid injection pipe 11.Easily occur what is blocked which solves shower nozzle
Situation, improves the absorptivity of fluorine gas, reduces the working time of cleaning, improves the operating efficiency for absorbing fluorine gas.
