Problems solved by technology

(2) Comprehensive ventilation: In most cases, the work station moves and the workpiece does not move, and the smoke and dust generation point changes constantly, so it is impossible to collect the smoke with a partial exhaust hood
This method can discharge part of the smoke and dust to the outside, but the actual smoke exhaust effect is not obvious. The smoke and dust concentration in most of the workers' operating areas far exceeds the allowable value. In addition, the smoke and dust discharged without purification treatment will also affect the workshop and the environment. Air pollution around the factory area

Abstract

The invention discloses a composite purification device and process suitable for dusty gas, and a purification device. The purification device comprises: a dust hood for collecting dusty flue gas; aninduced draft fan used for providing power for conveying the dusty flue gas; and a purification tower, wherein a flow guide device, a first spraying layer, a liquid holding turbulator, a filler layerand a second spraying layer are sequentially arranged in the purification tower from bottom to top, a flue gas inlet of the purification tower is positioned below the first spraying layer and is communicated with the dust hood through the induced draft fan, and the flow guide device is a half-tube type flow guide device. Due to the fact that the dust removal device of the process system adopts thecomposite purification tower, clean emission of gas can be achieved, and pollution to the surrounding environment is reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization and dust removal, in particular to a composite purification device and a purification process suitable for dust-containing gas. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Arc welding is the most commonly used welding method at present. When welding, under the condition of high-temperature arc, the end of the electrode and its base metal are melted correspondingly, and the surface of the molten liquid is violently sprayed with high temperature and high pressure generated by the coating and the welding core. The steam spreads around. As the vapor enters the surrounding air,...
