A kind of industrial by-product treatment device

摘要

The present invention relates to an industrial by-product processing apparatus, including a degassing vessel, the bottom of the degassing vessel is connected to the liquid recovery vessel through a straight pipe, the side of the degassing vessel is also connected to one end of the mixing tube, Is connected to the outlet of the waste acid transport pipe, the mixing pipe is also connected to a sodium sulfide (Na ₂ S) pump, the top of the degasser is connected to the scrubber via a Z-shaped pipe, and Mr. is installed, and the top of the demister is connected to the sealed vacuum pump and the steam trap through the transport pipe. In this industrial by-product treatment system, NaHS generated from alkali washing is reacted with waste acid generated during the weaving process in a mixing tube through Na ₂ S pump to obtain H ₂ S, NaSO ₄ , H ₂ O, etc. Up through the mixing tube into the degassing chamber, the primary separated gas enters the scrubber tower, lowering the temperature and further removing H ₂ O; Subongsik rear sent from the vacuum pump to a steam trap to remove the more H ₂ O, into the liquid divides the system is a high concentration of sulfuric acid is generated, so good recovery and treatment of the base effects, such as a H ₂ S containing the S and the resulting by-product The market outlook for high concentration sulfuric acid is better.
