An energy-saving device for aeration of desulfurization wastewater

Abstract

This utility model discloses an energy-saving aeration device for desulfurization wastewater, belonging to the field of desulfurization wastewater treatment. It includes an instrument air storage tank, a wastewater buffer tank, and an air supply assembly connecting the two. The air supply assembly includes an outlet pipe, a connecting pipe, and an annular branch pipe arranged sequentially along the outlet direction. The outlet pipe is installed on the instrument air storage tank and is equipped with a shut-off valve. One end of the connecting pipe is detachably connected to the outlet pipe, and the other end extends into the wastewater buffer tank. The annular branch pipe is installed inside the wastewater buffer tank and is a closed annular pipe with multiple aeration holes, each equipped with a one-way valve. This energy-saving aeration device for desulfurization wastewater utilizes the instrument air storage tank to aerate the wastewater in the wastewater buffer tank, thereby replacing the traditional Roots blower and preventing high-frequency failures such as impeller wear, oil leakage, and vibration from the source.
