| titleOfInvention | One kind being applied to BF Gas Washing water zero-emission water treatment technology |
| abstract | The invention discloses one kind to be applied to BF Gas Washing water zero-emission water treatment technology, include the following steps: to collect remittance return water chute after BF Gas Washing water washs coal gas by Wen's tower, 0.1mg/L sodium hydroxide is first added in chute inlet, PH is controlled in 8.3-9, then adds 0.001mg/L-0.1mg/L sodium carbonate；The poly-ferric chloride that concentration is 15-25mg/L is added in the middle part of return water chute；Then before washing water enters width sedimentation tank, the polyacrylamide that concentration is 0.5-1.0mg/L is added；Width sedimentation tank supernatant is successively passed through hot well and cold water well, sulfuric acid is added in cold water well, pH value is down to 7.5 or less；The water in cold water well is pumped into blast furnace aditus laryngis finally by water supply pump, the dirt dispersion agent that concentration is 2-4mg/L is added at pump intake.The present invention is sufficiently created dirt dispersion agent applicable elements, is washed away mitigation scale problems by physics, there is scale-inhibiting properties more better than similar scheme by chemically and physically method, science adjustment water quality, at the same solve they it is at high cost, need the problems such as discharging. |
