Three-pass dedusting devulcanizer

Abstract

The invention relates to a three-pass dedusting devulcanizer comprising a cyclone barrel, a fluid director and a filter, wherein the top port of the cyclone barrel is connected with the fluid director; the cyclone barrel is provided with a Venturi throat; the outer side of the cyclone barrel is provided with a wind inlet; atomization nozzles are respectively arranged on the inner side of the wind inlet and in an air flue above the Venturi throat; a plurality of inclined guide plates are staggered from top to bottom in the fluid director; and three to five filter layers are successively distributed from bottom to top in the filter. The three-pass dedusting devulcanizer has the beneficial effect that two-time spray dosing is carried out in the dedusting and devulcanizing process to fully blend with gas to react and be subjected to tertiary filtration, thereby obviously improving the devulcanizing effect, and greatly bringing convenience for energy conservation and emission reduction. The three-pass dedusting devulcanizer has the characteristics of small volume, low use cost, small power consumption, small water consumption amount, stronger expansibility and the like, is convenient to maintain, can be widely used for dedusting and devulcanizing air pollution, such as industrial waste gas, blast furnace gas, boiler smoke and the like, and is used for treating other harmful gases.

Description

Technical field [0001] The invention relates to a dust removal and desulfurization device for gases such as flue gas, dust, tail gas, harmful gas and the like generated in an industrial production process, and in particular to a three-pass dust removal and desulfurization device. Background technique [0002] For industrial producing countries, a large amount of industrial exhaust gas is produced every year, causing rapid deterioration of the social environment, and at the same time causing great harm to the ecological environment and living environment, directly or indirectly causing "acid rain" and climate warming in recent years. At present, various countries have continuously strengthened environmental protection, especially the treatment of industrial exhaust gas and dust. Environmental protection enterprises currently use a wide variety of processes to control industrial exhaust gas, but they generally consume large amounts of energy and water. Large, large area, large inve...

AI Technical Summary

Problems solved by technology

At present, environmental protection in various countries, especially the treatment of industrial tail gas and dust, is also continuously strengthened. Environmental protection companies currently use a variety of processes for the treatment of industrial tail gas, but the common problems are large energy consumption and water consumption. Disadvantages such as large size, large floor area, large investment, and low desulfurization efficiency
