Description

A device for eliminating sulfur dioxide exhaust gas and dust

technical field

The utility model relates to the technical field of waste gas treatment, in particular to a device for eliminating sulfur dioxide waste gas and dust.

Background technique

At present, the energy supply in most areas still adopts the method of burning coal. When burning coal, a large amount of exhaust gas will be generated. These exhaust gases carry sulfur dioxide and soot particles, and direct discharge will cause serious environmental pollution. Therefore, it is necessary to carry out internal pollutants. Eliminate processing.

When the current elimination devices purify the sulfur dioxide and smoke in the exhaust gas, most of them use the steps of dust removal first and then treatment of sulfur dioxide. The dust removal generally adopts the method of water mist dust reduction, but due to the influence of external air into the equipment, the smoke is in the interior of the device. With a certain flow rate, the flow rate is difficult to control, resulting in the smoke and dust flowing inside the device cannot fully contact the water mist, resulting in a low dust suppression effect, which makes subsequent problems in the treatment of sulfur dioxide, and because the flue gas is distributed in a large area inside the device Potential difference, the water mist first contacts the flue gas at the top after spraying out, and then absorbs the dust particles to drop, which reduces the purification effect on the flue gas at the bottom. Although the water mist will continue to spray, the flue gas will also continue to flow Therefore, it is necessary to keep the water mist spraying out for a long time after the flue gas is introduced, which is a waste of water resources.
