Technical specification for disposal of fluorine - containing waste gas

1 Scope

This standard specifies the main components of fluorine-containing waste gas, treatment and disposal methods and environmental protection requirements. This standard applies to wet phosphoric acid and phosphate fertilizer produced in the process of production of fluorine.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. GB 7744 Industrial hydrofluoric acid GB 7746 Industrial anhydrous hydrogen fluoride Emission standard for odorous pollutants GB 14554 GB 16297 Integrated Emission Standard for Air Pollutants HG/T 4692 Industrial ammonium fluorosilicate

3 fluorine containing the main components of waste gas

The main components of fluorine-containing waste gas are silicon tetrafluoride (SiF4) gas and hydrogen fluoride (HF) gas.

4 Dispose of disposal methods

4.1 Production of ammonium fluorosilicate 4.1.1 Principle Ammonium fluoride solution is used to absorb the fluorine-containing waste gas to obtain the ammonium fluorosilicate solution, crystallized by cooling, centrifuged and dried to obtain the finished product. Its reaction The equation is as follows. SiF4 2NH4F → (NH4) 2SiF6 The ammonium dilute ammonium silicate reacts with ammonia to give a lower concentration of ammonium fluoride solution, which can be used to absorb fluorine-containing waste gas The reaction equation is as follows. (NH4) 2SiF6 4NH3 2H2O → 6NH4F SiO2 Ammonium fluoride solution can also be used to absorb fluorine-containing waste gas to obtain ammonium fluoride solution, without cooling crystallization and direct access to ammonia, can be concentrated High ammonium fluoride solution, ammonium fluoride solution can be used for the preparation of such as ammonium fluoride, ammonium hydrogen fluoride, aluminum fluoride and other inorganic fluoride. At the same time can be added Water diluted part of the higher concentration of ammonium fluoride solution, diluted for the absorption of fluorine-containing waste gas. 4.1.2 Process flow A tower and two towers with a concentration of 15% to 25% of the ammonium fluoride solution as the absorption medium, the three towers of water as the absorption medium, A tower and two towers absorb the formation of ammonium fluorosilicate, at this time the basic absorption of fluoride exhaust gas is completely complete, and the absorption of a tower with three towers and two towers are not completely absorbed The amount of fluorine-containing waste gas, while a tower and the two tower ammonium fluoride solution volatile ammonium fluoride, ammonium fluorosilicate and free ammonia for washing absorption. A tower of suction ......
