AI Technical Summary

Technical Problem

In existing high-temperature, high-oil wastewater flotation devices, the mixing of reagents with oily wastewater is inconvenient, resulting in reduced separation efficiency and making it difficult to improve the separation efficiency of oily wastewater.

Method used

A mixing cylinder is installed on one side of the flotation cylinder and connected to a chemical tank via a delivery pipe. A water pump delivers the chemicals to the mixing cylinder, where they are mixed by stirring blades and microbubbles are generated by an aeration disc. The oil film is separated using a separation pipe and a float structure.

Benefits of technology

It improves the mixing efficiency of the agent and the wastewater, enhances the separation effect of oil and grease, and achieves efficient oil and wastewater separation.

Abstract

This utility model discloses a high-efficiency, high-temperature, and high-oil wastewater flotation system, relating to the field of wastewater treatment technology. The wastewater flotation device includes a flotation cylinder and a mixing cylinder disposed on one side of the outer middle layer of the flotation cylinder, with the mixing cylinder communicating with the interior of the flotation cylinder. A reagent tank is installed above the mixing cylinder and is fixed to the outer side of the flotation cylinder by a fixing bracket. A conveying pipe is connected to the bottom of the reagent tank. Simultaneously, as the oily wastewater enters the mixing cylinder, a water pump synchronously conveys the reagent from the reagent tank to the interior of the mixing cylinder, allowing the reagent to contact the oily wastewater and enter the flotation cylinder together. At the same time, a motor-driven stirring blade is installed at the end of the mixing cylinder, allowing the reagent and oily wastewater to contact the stirring blade and mix together under the rotation of the stirring blade before entering the flotation cylinder.
