Environment-friendly dust removal device for blast furnace tail gas

The utility model belongs to the technical field of environment-friendly dust removal devices, and particularly relates to an environment-friendly dust removal device for blast furnace tail gas, which is characterized in that a spraying dust removal cavity, a heating dehumidification cavity and an electrostatic adsorption cavity which are communicated with one another are sequentially arranged in a dust removal box from left to right according to the airflow direction; the air inlet and the drain outlet are located below the spraying dust removal cavity, the exhaust port is located above the electrostatic adsorption cavity, the channel between the spraying dust removal cavity and the heating and dehumidifying cavity is located above the partition plate, and the channel between the heating and dehumidifying cavity and the electrostatic adsorption cavity is located below the partition plate. Therefore, blast furnace tail gas entering from the air inlet can enter the heating and dehumidifying cavity from bottom
