How to deal with anhydrous hydrofluoric acid waste liquid
Thread Content
1. The company plans to use lithium hydroxide solution (the company’s by-product) for absorption. What are the precautions? 2. There is no place to put the neutralizer tank. I plan to put it on the roof of a 14-meter-high building. What should I pay attention to? 3. When exhaust gas is usually discharged, there is always no time to react, and the HF gas flows into the air. The manufacturer of anhydrous hydrofluoric acid recommends installing a sprinkler head, but I checked the information and found that the flow rate is too small due to the small spray hole. It is enough when spraying exhaust gas at ordinary times, but in an emergency, the waste liquid must be discharged quickly, and more than 10 sprinkler heads are needed based on the flow rate. Do we need to have 2 channels, 1 for exhaust and 1 for drainage?
Design according to the specifications of the absorption tower, local methods will not work
