| titleOfInvention | A kind of internal defoaming lead paste ammonium bicarbonate desulfurization method and device |
| abstract | The invention discloses a method and a device for desulfurization of lead paste ammonium bicarbonate with internal defoaming. In the defoaming area in the upper part of the desulfurization tank, 2 to 4 defoaming buckets are arranged, and the shearing action of the defoaming stirrer is used to lift the The converging and growing air bubbles are re-dispersed into small air bubbles, thereby effectively reducing the rise of the liquid level. The lead paste is prepared into a slurry with a solid content of 30-70% in the desulfurization tank. The total amount of the desulfurizer ammonium bicarbonate is 2.02 to 2.10 times the amount of lead sulfate in the lead paste, and is added to the desulfurization tank in batches. The speed of the agitator is kept at 70~120r/min, the foam layer reaches the defoaming area and the defoaming agitator is turned on, and the speed is kept at 100~200r/min, and the mass concentration of ammonium bicarbonate in the desulfurization tank is controlled to be no more than 5% in the whole process. It greatly reduces the rise of the liquid level in the desulfurization tank, solves the problem of volume expansion caused by a large amount of foaming, and greatly improves the desulfurization rate; the operation is stable, the operation is simple, and the environmental benefits are good. |
