7. The energy-saving environment-friendly industrial flue gas desulfurization and dust removal device according to any one of claims 1 to 6, characterized in that: the water curtain water spraying nozzle drops in a liquid drop mode.
8. A treatment method of an energy-saving environment-friendly industrial flue gas desulfurization and dust removal device is characterized by comprising the following steps: the energy-saving environment-friendly industrial flue gas desulfurization and dust removal device applied to any one of claims 1 to 7, wherein the treatment method comprises the following steps:
s1, starting an induced draft motor, sucking gas from an air inlet, filtering the gas by primary particles through a first filter screen, and then filtering and dedusting the gas by a plurality of dedusting filter screens;
s2, enabling the filtered gas to flow into a desulfurization and dehumidification chamber, enabling sulfur oxides in the gas to react with sodium hydroxide water mist sprayed by an atomizing nozzle to generate sulfate and water, enabling the gas to flow into the lower part of a partition plate from a connecting port, removing the residual sulfur oxides in the gas after water drops of a plurality of groups of water curtain water spray nozzles are purified, enabling the partition plate I to adsorb the water mist, and enabling liquid drops to flow back into a sodium hydroxide solution tank from the connecting port to be recycled;
s3, the gas flows into the lower part of the first condensation plate from the left side of the partition plate, then flows into the lower part of the second condensation plate from the right side of the first condensation plate, then flows into the upper part of the second condensation plate from the left side of the second condensation plate, and finally flows out of the gas outlet pipe, wherein the residual water mist in the gas can be removed by the first condensation plate and the second condensation plate, and the purification is completed.
