| titleOfInvention | A kind of treatment system of boron trifluoride tail gas |
| abstract | The utility model discloses a boron trifluoride tail gas processing system, which comprises a lye absorption tower, a calcium fluoride reaction kettle, a lime water preparation tank, a calcium fluoride centrifuge, a calcium metaborate reaction kettle and a calcium metaborate centrifuge , lye circulation tank. The utility model firstly uses the NaOH solution to absorb the lye in the lye absorption tower, then uses Ca(OH) 2 to carry out segmental treatment, firstly reacts in the calcium fluoride reactor to obtain the first by-product calcium fluoride, and then raises the temperature , the second by-product calcium metaborate is obtained by the reaction in the calcium metaborate reactor, so the by-products of calcium fluoride and sodium metaborate can be recovered, so the whole set of treatment system can improve economic benefits and has better practical significance. |
