Technical Field
The invention relates to the technical field of environmental protection, in particular to a dandelion-like self-falling type filtering device for purifying heavily polluted waste gas.
Background
The waste gas purification mainly refers to the treatment of industrial waste gas generated in industrial places, such as dust particles, smoke and dust, peculiar smell gas and toxic and harmful gas. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas peculiar smell purification, acid-base waste gas purification, chemical waste gas purification and the like.
The treatment of the exhaust gases should be carried out from two sides: firstly, the waste gas dust removal aiming at suspended granular pollutants; secondly, the control of purifying the gaseous pollutants by the waste gas of the gaseous pollutants is mainly to separate the pollutants from the waste gas by utilizing the differences of physicochemical properties such as solubility, adsorption saturation, dew point, selective chemical reaction and the like; or to convert the contaminants into harmless or easily disposable substances. Basic methods for purifying exhaust gas include absorption, adsorption, condensation, catalytic conversion, and combustion.
