Inclined plate settling separating device

Abstract

The invention relates to an inclined plate settling separating device which comprises a tower, an inlet for ammonium sulfate slurry carrying dust, a dust deposition area, an finished product area, a finished product outlet area and a dust deposition discharge port, wherein an inclined plate separating device in the tower comprises an upper upright type inclined plate separator and a lower inclined type inclined plate separator; the upper upright type inclined plate separator is composed of an upper inclined plate component, an inclined plate supporter and an upper support grid plate; and the lower inclined type inclined plate separator is composed of a lower inclined plate component, an inclined plate supporter and a lower support grid plate. By adopting the technical scheme of the invention, the problem that a finished product cannot be separated from dust effectively is solved; the flow field distribution and flow speed of the ammonium sulfate slurry carrying dust in the separating device are reasonable; the separating speed and the de-dusting efficiency are increased; the inclined plate settling separating device is simple in shape and can be conveniently processed and assembled; and aiming at the problem that dust is gathered in a desulfurizing tower and cannot be cleared off and the stable running effect is seriously influenced, the inclined plate settling separating device can be widely applied to a process of a wet flue gas desulfurization de-dusting system and can meet the requirement of 10m<3>-550m<3> ammonium sulfate slurry de-dusting treatment.

Description

technical field [0001] The utility model relates to a wet flue gas desulfurization and dust removal equipment, in particular to an inclined plate sedimentation and separation device in the wet flue gas desulfurization and dust removal equipment. Background technique [0002] In the existing wet desulfurization process, in order to remove the dust in the flue gas, it is necessary to remove the dust before removing the sulfur dioxide gas. However, most of the dust removal equipment before the current desulfurization system adopts the electric dust removal method. To achieve a high dust removal efficiency, it is still difficult to remove extremely fine dust, so that the fine dust will be enriched in the post-process desulfurization system, directly leading to the paralysis of the desulfurization tower, seriously affecting the stability of the desulfurization system and long-term safe operation. Contents of the invention [0003] In view of this, the technical problem to be so...
