The binary compound that hydrogen fluoride is made up of fluorine element and protium is the gas of colourless irritant smell, is a kind of Weak monoacid.Hydrogen fluoride and the aqueous solution thereof are all toxic, easily make bone, deformity teeth, and hydrofluoric acid can through skin by mucous membrane, respiratory tract and gastrointestinal tract, should emergency processing immediately after poisoning, and deliver to and seek medical advice, and generate fluorine metaantimmonic acid after mixing with antimony pentafluoride.
In hydrogen fluoride production, industrial tail gas is mainly SiF
4, also have HF, SO
2deng, need absorb pay product fluosilicic acid with Water spray, reaction equation is as follows:
①SiF
4+H
2O→H
2SiF
6+SiO
2
②SiO
2+HF→SiF
4
As can be seen from reaction equation, after process tail gas enters water wash system, constantly generate fluosilicic acid through hydrolysis, constantly separate out silica white gum thing again, these SiO simultaneously
2as reacted with the HF in process tail gas not in time, will be attached on the filler in absorption tower, time serious, causing stifled tower, destroy negative pressure and cause safety and environmental protection accident, that is, in process tail gas water-washing process, certain HF being had as rationally consuming supply.
In prior art, pay during AHF produces and produce calcium sulfate, calcium sulfate is gray solid powder, temperature is about 200 DEG C, containing sulfuric acid, HF and water vapour, have a large amount of acid gas and dust in the collection of calcium sulfate and entrucking process, these acid gas and dust, as dealt with improperly, can cause surrounding enviroment and have a strong impact on.At present, adopt slag aspiration receiving apparatus, when slag gas absorbing liquid has arrived finite concentration, waste water processing station is sent to and carry out neutralisation treatment, qualified discharge.So the acid not only wasted in absorbing liquid is mainly HF, but also consumes a large amount of alkali, also needs manpower, equipment and factory building.
Utility model content
The purpose of this utility model is to provide a kind of hydrogen fluoride slag charge waste gas recovering device, and apparatus structure is simple, and easy to operate, power consumption is low, economize energy, reduces tail gas, protection of the environment.
A kind of hydrogen fluoride slag charge waste gas recovering device described in the utility model, comprise reaction converter, reaction converter is connected with cooling stove by pipeline, cooling stove is connected with the top of elevator by slag tracheae, cooling stove is connected with the bottom of elevator by slag charge pipe, and elevator top is connected with feed bin by pipeline, is connected in the middle part of elevator by pipeline with the first water scrubber, first water scrubber is connected with the second water scrubber by pipeline, and the second water scrubber is connected with chimney by pipeline; Second water scrubber is connected with the second rinsing bowl by pipeline, and the second rinsing bowl is connected with the first rinsing bowl by the first pipeline, and the first rinsing bowl is connected with hydrogen fluoride storage tank by pipeline, and hydrogen fluoride storage tank is connected with system recoveries tank by the 3rd pipeline; First water scrubber is connected with the first rinsing bowl by pipeline, and the first rinsing bowl is returned by the second pipeline and links the first water scrubber.
First pipeline, the second pipeline, the 3rd pipeline all arrange pump.
