Abstract

The invention belongs to a composite high-efficiency wet dust collector and its dust removal process; it includes an induced draft fan connected to a boiler flue gas discharge pipe, and the induced draft fan is connected to the lower gas inlet of the wet dust collector through the first inlet of the Venturi. The dust collector includes a wet dust collector cylinder, the top of the wet dust collector cylinder is provided with a chimney, the inner middle of the wet dust collector cylinder is provided with several layers of spray pipes, and the lower parts of several layers of spray pipes are sequentially provided with gas distributors and A cover plate, a flue gas pipe is arranged between the gas distributor and the cover plate, and two vortex dust removal plates are installed on the lower part of the cover plate corresponding to the lower gas inlet of the wet dust collector; there are investment costs Low cost, reasonable design, simple structure, strong applicability, and the advantages of integrated dust removal and desulfurization.

Description

technical field [0001] The invention belongs to the technical field of flue gas dust removal, and in particular relates to a composite high-efficiency wet dust collector and a dust removal process thereof. Background technique [0002] With the rapid development of industry, the emission of a large amount of smoke and dust has caused serious pollution to the environment and affected the survival and health of human beings. The existing wet dust collector utilizes the inertial collision and mixing of water droplets and smoke to make the smoke particles be carried away by the water flow. So as to achieve the purpose of dust removal. Due to the problems of insufficient gas-liquid contact mixing and short contact time in the existing wet dust collector, the dust removal efficiency of the dust collector is low and the effect of improving the environment is not significant. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies ...
