Ozone Generation System

Introduction and Application Scope of Ozone Generation System:

Anozone generatoris a device used to produce ozone gas (O₃). Ozone (O₃) is a gas with strong oxidizing properties, more chemically active than oxygen. Ozone generators use air or oxygen as raw materials to produce ozone through high-frequency high-voltage discharge. This chemical reaction can be expressed as 3O₂→2O₃. The ozone molecule has one more oxygen atom than the ordinary oxygen molecule, making ozone a strong oxidant capable of rapidly killing bacteria in the air at a certain concentration. This strong oxidizing property makes ozone an efficient disinfectant.

Main Application Scope of Ozone Generators:

● Municipal sewage disinfection
● Municipal water supply
● Decolorization and COD degradation of industrial chemical wastewater
● Swimming pool disinfection
● Aquaculture wastewater treatment
● Space disinfection

Classification and Main Equipment Introduction of Ozone Generation System:

By hourly ozone output: Divided into small ozone generators (10g/h–800g/h) and large ozone generators (1kg/h–100kg/h).
By gas source: Air-source type (uses dry, clean compressed air as raw material) and oxygen-source type (uses industrial oxygen or on-site oxygen generation as raw material).
By installation method of ozone generation units: Vertical (ozone generation units installed vertically) and horizontal (ozone generation units installed horizontally).
The entire ozone generator consists of 1 ozone generation chamber, 1 set of dedicated power supply system, 1 set of operation control system, 1 set of cooling device, and 1 set of instrumentation pipeline valves.

Process Flow of Ozone Generation System:

Main Equipment Features of Ozone Generation System:

Ozone Generation Chamber: Composed of single or multiple ozone generation units. Each unit is the basic component for ozone production, consisting of a dielectric, electrodes separated by the dielectric, and a discharge space. Under high-frequency electric fields, electrodes generate discharges, ionizing oxygen molecules in the air on the ozone tube electrodes into ozone molecules. The ozone molecules are collected after treatment to form the final product.
Power Supply System: Converts input power-frequency AC power into medium-frequency high-voltage AC power, including rectifier circuits, inverter circuits, reactors, high-voltage transformers, and control devices. The rectifier-inverter circuit converts power-frequency AC to medium-frequency AC required for discharge, which is then stepped up by the high-voltage transformer and delivered to the ozone generation chamber to form a high-voltage electric field.
Cooling System: Uses water cooling to effectively dissipate heat generated during discharge through sufficient cooling water of qualified quality. The cooling water system can be configured based on the customer’s on-site water source: self-provided qualified cooling water, closed-circuit circulating cooling water using a plate heat exchanger, or a chiller system.
Instrumentation Pipeline System: Equipped with instruments and valves for detecting and adjusting flow, pressure, temperature, etc., to regulate ozone gas flow. The types of instruments and valves (on-site or online) can be selected to meet user requirements, enabling manual or fully automatic control for convenient monitoring.
