Ozone Test Chamber

It is suitable for a series of tests on color fastness and color fastness to airborne contaminants, such as knitted fabrics, woven fabrics, synthetic fiber fabrics, natural fiber fabrics, etc. It can also be used for the ozone color fastness test of fabrics such as nylon carpet.

Application

Ozone testing laboratories have wide applications in various fields, including but not limited to:

Material aging testing: Used to evaluate the aging resistance of non-metallic materials and rubber products under ozone conditions.

VOCs degradation research: Used to study the oxidative degradation effect of ozone on volatile organic compounds (VOCs).

Laboratory disinfection: Used to disinfect laboratory equipment and environments, ensuring safety and hygiene.

Food processing: Used for disinfection and treatment in food processing workshops, ensuring food safety.

Medical and health: Used for disinfection and treatment in the medical and health field, ensuring safety and hygiene.

Parameter

Accessoriess

Ozone laboratory accessories can be categorized into four main types based on experimental needs: core equipment, supporting devices, safety protection equipment, and auxiliary accessories. The details are as follows:

I. Core Equipment

Ozone Generator

Function: Generates ozone gas; the core equipment for the experiment.

Ozone Detector

Function: Monitors ozone concentration in real time, ensuring experimental safety and data accuracy.

II. Supporting Devices

Ozone Reactor

Function: Provides the contact environment between ozone and reactants (such as liquids and gases).

Ozone Exhaust Gas Destroyer

Function: Treats unreacted ozone, preventing its release into the environment.

Gas/Liquid Flow Meter

Function: Precisely controls the flow rate of ozone, oxygen, or reaction liquid.

Water Tank and Pump

Function: Stores and transports reaction liquids (such as water samples), maintaining experimental continuity.

III. Safety Protection Equipment

Ventilation System

Function: Maintains air circulation in the laboratory, preventing ozone accumulation.

Ozone Leakage Alarm

Function: Real-time monitoring of ozone concentration in the environment; automatic alarm when ozone levels exceed the limit.

IV. Auxiliary Accessories

Pipelines and Valves

Function: Connects various devices and controls gas/liquid flow.

Circuit Control System

Function: Integrates control of the start/stop and parameter adjustment of ozone generator, detector, water pump, and other equipment.

V. Optional Expansion Accessories

Oxygen Generator: Provides a high-purity oxygen source for the ozone generator, increasing ozone production and concentration.

Data Acquisition System: Records parameters such as ozone concentration, flow rate, and temperature during the experiment for data analysis.

Temperature Control Device: Maintains stable temperature inside the reactor (e.g., heating or cooling module).

Test Procedures

To improve the safety and effectiveness of ozone generators during daily use, the following procedures should be followed:

1. Start-up Procedure

1.1. Open the generator cooling water valve to supply cooling water to the generator. Keep the outlet open until normal water flow is achieved.

1.2. Start the air compressor, open the air outlet valve, and simultaneously open the cooler inlet valve. Adjust the air compressor outlet pressure to 0.5-0.7 MPa.

1.3. Close the air switch in the control cabinet. The display screen on the control cabinet door will show "System Normal, Standby". Touch the start button on the touch panel. A countdown air purging will then begin. The dryer solenoid valve will automatically open. The pressure gauge on the dryer should show a pressure of approximately 0.6 MPa. Simultaneously adjust the pressure reducing valve to 0.04-0.08 MPa as needed (the dryer cylinder should be switched every 5 minutes). Also, open the ozone valve at the oxidation tower inlet. Check the ozone gas distribution at the oxidation tower sight glass.

1.4 After the air purging time is over, press the start button. The generator will operate at high voltage. Press the start/up button to increase the voltage to 8KV. After running for 10 minutes, adjust the voltage to 10KV and observe the values on the display screen. For detailed operation of the control cabinet, please refer to the "Power Control System User Manual".

1.5 After normal operation, observe the emission of light from the generator and the counts of each instrument, and record the results.

1.6 As needed, open the drain valves of the cooler and gas storage tank periodically to drain the gas, generally every 30-60 minutes.

2. Shutdown Procedure

2.1 First, stop the water supply to the oxidation tower, then close the water inlet valves of the generator and cooler.

2.2 Press the drain button on the panel to reduce the voltage to zero, then press the stop drain button. The generator high voltage will stop operating, and a countdown will begin to purge the residual ozone gas inside the generator.

2.3 After the countdown purging is complete, shut down the air compressor, close the ozone inlet valve of the oxidation tower, and press the stop/exhaust button to disconnect the air switch in the control cabinet; otherwise, the warranty will be void.

2.4 In winter, after closing the water inlet valves of the generator and cooler, to prevent damage to the internal components of the generator from freezing, the drain valve below the generator must be opened to drain any remaining water from the generator and cooler; otherwise, the warranty will be void.
