Wet-type flue gas dust removal device

Abstract

The invention discloses a wet-type flue gas dust removal device, comprising a barrel, wherein a water inlet is formed at the upper part of the barrel, while a drain outlet is formed at the lower part. A flue gas inlet pipe is arranged at the bottom of the barrel, while an exit pipe is arranged on the upper part of the barrel. A layer of screen is horizontally arranged in the barrel from bottom upwards; a stirrer is suspended in the barrel; the stirring shaft of the stirrer is arranged vertically and a stirring paddle is arranged at the end portion of the stirring shaft, and the stirring paddle is located at the upper part of the screen; or a plurality of layers of screens are horizontally arranged in the barrel from bottom upwards, a stirrer is suspended in the barrel, the stirring shaft of the stirrer is arranged vertically, a plurality of stirring paddles with the number same as the number of the layers of screens are arranged at the end portion of the stirring shaft, and each stirring paddle is correspondingly located at the upper part of each screen. Furthermore, a sprayer is arranged at the internal top of the barrel. The wet-type flue gas dust removal device is simple in structure, low in cost, multilayer, varied in comprehensive dust removal ways and good in flue gas dust removal effect.

Description

technical field [0001] The invention relates to a flue gas dust removal device, in particular to a dust removal device which adopts wet dust removal for flue gas containing particles. Background technique [0002] At present, flue gas dust removal, especially flue gas dust removal containing particles, has a high dust content and high humidity, and cloth bag dust removal is used. The dust removal effect will cause damage to the device, and other wet dust collectors such as spray are also used, but the dust removal effect is poor and the efficiency is low. Such as CN200420045021.7 utility model, a kind of comprehensive network water dust removal filter, main body, air inlet, air outlet, front filter screen block, rear filter screen block, inclined filter screen group, water inlet, water outlet, adopt multi-stage filtration , purification method, can carry out sufficient air dust removal for a long time and without interruption, effectively eliminate various harmful substanc...

Problems solved by technology

However, the contact area between flue gas and water in this utility model is limited, and the flue gas containing a large amount of particulate matter is discharged without being fully mixed and contacted with water, so the dust removal effect is not good, and the particulate matter in the flue gas is also easy to cause mesh holes clogging, which makes the dust collection effect worse
