Technical field
The utility model relates to a kind of cyclic absorption device (condensation heat exchange device), specifically a kind of fluosilicic acid cyclic absorptions
Device belongs to chemical equipment technical field.
Background technique
Hydrofluoric acid (English: Hydrofluoric Acid) is the aqueous solution of hydrogen fluoride gas.It is produced during Acid of Hydrofluoric Acid Production
Raw fluosilicic acid is entered after circulating slot by absorption tower and goes successively to tail gas absorber cyclic absorption.As application publication number is
A kind of fluosilicic acid Comprehensive recycle technology, the technique disclosed in CN106587073A patent document disclose: clear water is added
In fluorine absorption cycle slot, after the fluoro-gas that cyclic absorption is overflowed, circulation fluid enters to be cooled in low dose fluoride silicic acid storage tank
Enter defluorinate system after precipitating, silica gel defluorination residues are removed after defluorinate filtering, filter residue makees the use of product filler material, and filtrate is largely used
It is used as dilute sulphuric acid, the clear water that pole is spilled over to circulating slot at least partially through feed coefficient and newly supplements carries out absorption cycle again, drop
The clear water circulation fluid that low sulfuric acid consumption injects in fluorine absorption cycle slot for the first time circulation fluid after absorbing is sent to high-order low concentration
Fluosilicic acid storage tank is used as diluting concentrated sulfuric acid, and remainder, which enters in fluorine absorption cycle slot, to be absorbed.
Cooling coil in existing fluosilicic acid circulating slot can not be accomplished fluosilicic acid gas being completely cooled down to liquid, cause
A large amount of fluosilicic acid can be carried in exhaust gas secretly, cause environmental pollution.
Utility model content
The purpose of the utility model is to provide a kind of fluosilicic acid cyclic absorption device, which is reduced in exhaust gas
The entrainment of fluosilicic acid, reduces environmental pollution.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of fluosilicic acid cyclic absorption device, including cooling absorption plant, fluosilicic acid circulating slot and fluosilicic acid absorption tower, institute
It states cooling absorption plant, fluosilicic acid circulating slot and fluosilicic acid absorption tower to be cascaded, in the fluosilicic acid circulating slot and fluorine silicon
Be connected with feeding line on pipeline between acid absorption column, the feeding line is passed through fluosilicic acid, the cooling absorption plant and
It is provided with circulating pump and discharging pipeline on pipeline between fluosilicic acid circulating slot, goes out on the fluosilicic acid absorption tower with exhaust gas
Mouthful.
Preferably, the cooling absorption plant is graphite condenser.The cooling absorption plant and fluosilicic acid circulating slot
Between pipeline on be provided with valve.
In order to measure the liquid level in fluosilicic acid circulating slot, the fluosilicic acid circulating slot is provided with liquidometer.
In order to measure cooling absorption plant, the temperature in fluosilicic acid absorption tower, the cooling absorption plant, fluosilicic acid absorb
Tower is provided with thermo detector.
In order to discharge exhaust gas, sample tap is provided on the discharging pipeline.
The utility model passes through the strong heat transfer effect of graphite condenser, and fluosilicic acid is cooling, is placed in than original cooling coil
Effect is outstanding in slot, on the one hand can will optimize technique, the entrainment of removal fluosilicic acid in the offgas, meet the requirement of environmental protection.
On the other hand reduce the use of refrigerant to a certain extent, reduce energy consumption.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, a kind of fluosilicic acid cyclic absorption device, including graphite condenser 2, fluosilicic acid circulating slot 3 and fluorine silicon
Acid absorption column 4, the fluosilicic acid circulating slot 3 are provided with liquidometer, for measuring the liquid level in fluosilicic acid circulating slot 3, the stone
Black condenser 2, fluosilicic acid absorption tower 4 are provided with thermo detector, for measuring graphite condenser 2, the temperature in fluosilicic acid absorption tower 4
Degree.
The graphite condenser 2, fluosilicic acid circulating slot 3 and fluosilicic acid absorption tower 4 are cascaded, and follow in the fluosilicic acid
It is connected with feeding line 1 on pipeline (liquid phase pipeline) between annular groove 3 and fluosilicic acid absorption tower 4, the feeding line 1 is passed through fluorine
Silicic acid.It is additionally provided with vapor delivery line between the fluosilicic acid circulating slot 3 and fluosilicic acid absorption tower 4, plays balanced action.
It is provided with circulating pump 6 and discharging pipeline 7 on pipeline between the graphite condenser 2 and fluosilicic acid circulating slot 3, is
It is sampled analysis, is provided with sample tap on the discharging pipeline 7.Meanwhile the graphite condenser 2 and fluosilicic acid circulating slot
Valve is provided on pipeline between 3.
In order to discharge exhaust gas, there is waste gas outlet on the fluosilicic acid absorption tower 4.
In use, be first passed through a little clear water in fluosilicic acid circulating slot 3, after fluosilicic acid is put into fluosilicic acid circulating slot 3, fluorine
It opens circulating pump 6 after reaching a certain amount of in silicic acid circulating slot 3 to be recycled, sampling analysis opens circulating pump after reaching a certain concentration
6 get material, this operation is intermittently operated.And the exhaust gas that can not be cooled down then is discharged at the top of fluosilicic acid absorption tower 4.
Graphite condenser 2 guarantees that fluosilicic acid gas is completely cooled down to liquid, reduces the entrainment of fluosilicic acid in exhaust gas, reduces ring
Border pollution.
