Introduction

In-depth interpretation of the technical specification for the treatment and disposal of fluorine-containing waste gas

1. Scope and applicability of the standard

This standard applies to fluorine-containing waste gas generated in the production of wet phosphoric acid and phosphate fertilizers, mainly targeting two gas components: silicon tetrafluoride (SiF4) and hydrogen fluoride (HF).

Treatment method	Principle	Main equipment	Product quality requirements
Production of ammonium fluorosilicate	Use ammonium fluoride solution to absorb fluorine-containing waste gas to generate ammonium fluorosilicate solution, and obtain the finished product through cooling crystallization, centrifugal separation and drying.	Spray absorption tower, cooling crystallization tank, centrifuge, ammoniator, etc.	Meet HG/T4692 standard.
Production of anhydrous hydrogen fluoride	Fluorine-containing waste gas is absorbed to produce dilute fluorosilicic acid, which reacts with concentrated sulfuric acid to produce hydrogen fluoride and silicon tetrafluoride, and anhydrous hydrogen fluoride is obtained through distillation, condensation and rectification.	Reactor, distillation tower, condenser, rectification tower, etc.	Meet GB7746 standard.
Production of hydrofluoric acid	Anhydrous hydrogen fluoride is absorbed by desalted water or pure water to produce hydrofluoric acid.	Hydrogen fluoride absorber, hydrofluoric acid storage tank, vacuum pump, etc.	Meet GB7744 standard.

2. Background of Standard Formulation and Technological Evolution

The treatment of fluorine-containing waste gas is an important part of environmental protection, especially the fluorine-containing waste gas generated in the production process of wet phosphoric acid, which has serious harm to the environment and human health. This standard is formulated based on relevant domestic research and technical accumulation, aiming to standardize the treatment and disposal methods of fluorine-containing waste gas and ensure that the emission meets national standards.

3. Implementation Suggestions

Process Optimization:Enterprises should select appropriate treatment methods according to their own production scale and the characteristics of fluorine-containing waste gas, and continuously optimize the process flow.
Equipment Selection:Give priority to corrosion-resistant, efficient and stable equipment to ensure absorption efficiency and product quality.
Monitoring and Maintenance:Establish a complete monitoring system, regularly check the operating status of the equipment, and ensure the long-term stable operation of the treatment system.
Training and management: Provide professional training to operators to ensure that standard requirements are implemented
