Description
Technical field
The utility model relates to chemical technology field, is a kind of for reclaiming the hydrofluoric hydrofluoric acid retracting device of fluoridizing raffinate specifically.
Background technology
The waste liquid (fluoridizing raffinate) producing after large-scale fluoride reaction, wherein comprises a large amount of hydrogen fluoride and H
2o, sodium salt and some organic matters.Fluoridize the unprocessed direct discharge of raffinate and can cause serious environmental pollution.
Fluoridize at present raffinate and process the employing concentrated sulfuric acid conventionally, recycling physicochemical property reclaims hydrogen fluoride, yet this method can produce a large amount of sulfuric acid and waste material is difficult for processing, and must cause environmental pollution.
Utility model content
In order to overcome the defect of above-mentioned prior art, technical problem to be solved in the utility model is to provide and a kind ofly without sulfuric acid, directly reclaims and fluoridize the hydrofluoric hydrofluoric acid retracting device in raffinate.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of hydrofluoric acid retracting device, comprise vaporizer, sprayer, heater, condensing unit and discharge device, the top of described vaporizer is provided with charging aperture and gas outlet, the bottom of described vaporizer is provided with discharge gate, described sprayer is arranged on described charging aperture place down, described heater is arranged on the sidewall of vaporizer, and described condensing unit is connected with described gas outlet pipeline, and described discharge device is arranged on described discharge gate place.
Wherein, described discharge device is conveying worm.
Wherein, the bottom of described vaporizer is tapered, and described discharge gate is arranged on bottom and the sidewall junction of vaporizer.
Wherein, also comprise emptying negative pressure pump, described emptying negative pressure pump is connected with condensing unit pipeline.
The utility model compared with prior art, there is following beneficial effect: adopt hydrofluoric acid retracting device of the present utility model, thoroughly stopped the existing problem of environmental pollution of concentrated sulfuric acid processing method, and simple to operation, cost recovery is cheap, removal process can not introduced other impurity and pollutant, can not produce exhaust emission etc., there is good economic benefit and environmental benefit.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the utility model embodiment.
Label declaration:

5, condensing unit; 6, vaporizer; 7, emptying negative pressure pump.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1, the hydrofluoric acid retracting device of present embodiment, comprise vaporizer 6, sprayer 1, heater 2, condensing unit 5 and discharge device 4, the top of described vaporizer 6 is provided with charging aperture and gas outlet, the bottom of described vaporizer 6 is provided with discharge gate 3, and described sprayer 1 is arranged on described charging aperture place down, and described heater 2 is arranged on the sidewall of vaporizer 6, described condensing unit 5 is connected with described gas outlet pipeline, and described discharge device 4 is arranged on described discharge gate 3 places.
In the above-described embodiments, described discharge device 4 is preferably conveying worm.The bottom of described vaporizer 6 is preferably tapered, and described discharge gate 3 is arranged on bottom and the sidewall junction of vaporizer 6, to facilitate material to discharge smoothly emptying, avoids material to be deposited on the bottom of vaporizer 6.
In the above-described embodiments, also comprise emptying negative pressure pump 7, described emptying negative pressure pump 7 is connected with condensing unit 5 pipelines, for by the exhaust gas evacuation obtaining after condensation.
Operation principle of the present utility model is as follows: fluoridize raffinate and by sprayer 1, enter the interior droplet that forms of vaporizer 6 by pipeline, after the heating of heater 2 (heating-up temperature is advisable at 200-800 ℃), hydrogen fluoride in droplet and water upwards enter in condensing unit 5 by the gas outlet at vaporizer 6 tops with vapor form, through forming liquified hydrogen fluoric acid after condensing unit 5 cooling and reclaiming, the waste gas obtaining after condensation does not contain hazardous substance substantially, therefore can be directly emptying or emptying by emptying negative pressure pump 7, sodium salt in droplet and organic matter at high temperature form solid state powder, discharge gate 3 through vaporizer 6 bottoms enters in discharge device 4, again via the unified collection and treatment of discharge device 4.
Seen from the above description, adopt hydrofluoric acid retracting device of the present utility model, thoroughly stopped the existing problem of environmental pollution of concentrated sulfuric acid processing method, and simple to operation, cost recovery is cheap, removal process can not introduced other impurity and pollutant, can not produce exhaust emission etc., there is good economic benefit and environmental benefit.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
