Converter gas dehydrater

Abstract

The invention belongs to the field of steel and iron gas dust removal and relates to a converter gas dehydrater. The converter gas dehydrater comprises a shell and a folded plate layer arranged in theshell. The shell is provided with a smoke inlet and a smoke outlet which are separated by the folded plate layer. The shell is additionally provided with a gas flow equalizing device, and by means ofa plurality of venturi nozzles, particle collision and coagulation of the gas are enhanced; the folded plate layer is additionally arranged, a hexagonal through hole is formed as a fluid channel, sothat the gas flow direction is further changed, collision between water mist in the gas with the folded plate layer is enhanced, little water drops are coagulated into large water drops, and the dehydration effect of a cyclone is improved. The converter gas dehydrater can further improve the gas dehydration effect and lowers the water content of the gas, the dust content of the converter gas is further lowered, and ultra-clean emission is achieved.

Description

technical field [0001] The invention belongs to the field of iron and steel gas dedusting, and relates to a converter gas dehydrator. Background technique [0002] During the purification and recovery process of the primary flue gas of the converter, after the flue gas is cooled and washed by the spray tower, it must carry dust-laden mechanical water, and the water and dust content is ≥50mg / l. Therefore, it must be dehydrated before being sent to the user for use or discharged. At present, the dehydrators widely used in the primary dedusting system of converters are mostly inertial cyclone dehydrators and wire mesh dehydrators. Their dehydration efficiency is poor, which makes the flue gas carry a high amount of dusty water, and the chimney has a "rain" phenomenon. occur. At the same time, due to the increase in the amount of dusty water, the dust content of the flue gas is indirectly increased, which weakens the benefits of fine dust removal, and is not suitable for dehyd...

Problems solved by technology

At present, the dehydrators widely used in the primary dedusting system of converters are mostly inertial cyclone dehydrators and wire mesh dehydrators, and their dehydration efficiency is poor, which makes the flue gas carry a high amount of dusty water, and the chimney has a "rain" phenomenon occur

At the same time, due to the increase of the dusty water content, the dust content of the flue gas is indirectly increased, which weakens the benefits of fine dust removal, and is not suitable for dehydration after fine dust removal.
