AI Technical Summary

Technical Problem

In existing wastewater treatment devices, aeration discs have low ozone utilization rates and high operating costs, while high-efficiency dissolved air devices have high power water requirements and high energy consumption.

Method used

An ozone dosing device comprising an outer cylinder, an inner cylinder, a mixing nozzle, and a secondary mixing device is employed. This device utilizes the turbulent diffusion effect of the jet to improve the mixing efficiency of ozone and water, and prevents water backflow by using a backflow preventer, thereby reducing the demand for dissolved air water.

Benefits of technology

It improves ozone utilization, reduces dissolved air water demand, reduces electricity consumption and residual ozone emissions, and achieves energy conservation, emission reduction, and lower operating costs.

Abstract

This utility model discloses an ozone dosing device for advanced wastewater oxidation processes, relating to the field of environmental protection equipment technology. The utility model includes an outer cylinder and a pressurized water inlet. An air inlet is fixedly connected to the top of the outer cylinder. An inner cylinder is located inside the outer cylinder. One end of the pressurized water inlet passes through the outer cylinder and is fixedly connected to the inner cylinder. Several high-efficiency mixing nozzles are fixedly connected to the outer ring of the inner cylinder near the top. Several secondary mixing devices are fixedly connected to the outer ring of the outer cylinder, with the high-efficiency mixing nozzles and secondary mixing devices coaxial. Both the high-efficiency mixing nozzles and secondary mixing devices have a conical structure. There is an airflow space between the inner and outer cylinders. This utility model can improve mass transfer efficiency, increase ozone utilization efficiency, and reduce dissolved air water demand, thereby reducing ozone dosage, reducing power consumption, and reducing residual ozone emissions, achieving the goals of energy conservation, emission reduction, and lower operating costs.
