3Working principle

The plasma oil fume purifier uses a pulse high-voltage high-frequency plasma power supply and a toothed plate discharge device to generate high-intensity, high concentration, and high-energy active free radicals. In milliseconds, it instantly undergoes oxidation-reduction reactions on harmful exhaust gas molecules, degrading most pollutants in the exhaust gas into carbon dioxide, water, and easily treatable substances. Plasma purification technology refers to the use of high-energy electrons, ions, free radicals, and neutral particles generated by pulsed corona discharge at a rate of per second300Ten thousand times to3000Repeatedly bombarding odor producing molecules at a speed of tens of thousands of times, deactivating, ionizing, and cracking various components in the exhaust gas, causing a series of complex chemical reactions such as oxidation，Exists within the plasma(OH-、、O-2 H+TheO3)Directly open the molecular bonds between organic gas molecules to decompose harmful gases and ultimately emit themCO2TheH2OWaiting for harmless substances while generating a large amount of negative ions can freshen the air.

7Operation and usage instructions

7.1 Check before powering on

7.1.1 Power Supply Inspection

(1) Confirm that the input power is AC220V50Hz.

(2) Confirm that all power connectors are well connected.

7.1.2 Electric field inspection

(1) The iron sheet above the electric field should have good contact with the spring connecting the output end of the high-voltage package, and there should be sufficient safety distance from the box and other components.

(2) The electric field itself is intact and accurately positioned.

7.2 Power on use

7.2.1 After completing the pre power check, turn on the power and start the purifier.

7.2.2 After power on, the purifier should emit a continuous and steady "wheeze wheeze" sound-”Static discharge sound, the red light on the panel is the power indicator light, and the green light is the work indicator light. The green indicator light is on, indicating that the purifier has entered normal working mode.

If both the red and green indicator lights are not on, it means that the power supply has not been connected. First, check whether the power supply and wiring are working properly.

7.2.4 If the green indicator light does not light up, it indicates that the equipment is not working properly and professional maintenance personnel should be notified for inspection and maintenance.

8Common fault phenomena and troubleshooting methods

9. Maintenance and upkeep:

In order to ensure the purification efficiency of the purifier, the maintenance cycle of industrial oil fume purification equipment is set as30 days (subject to special circumstances)

9.1 Cleaning method:

Method 1: Remove the Oil King（YB-5 room temperature cleaning agent) and water, prepare the required cleaning solution in a ratio of 1:8.

Method 2: Use industrial caustic soda andPrepare the required cleaning solution in a 1:10 ratio for hot water above 70 degrees Celsius.

Method 3: Determine appropriate cleaning agents through experiments based on the properties and characteristics of the purified oil, such as degreasers, thinners, and other organic solvents.

9.2 Cleaning steps:

(1) Work preparation: electric field cleaning water tank, caustic soda, electric field cleaning tools, rubber gloves, brushes, water shoes, protective goggles, screwdriver.

(2) Cut off the power, open the maintenance door, and record the position of the electric field for installation after cleaning is completed (you can take photos with your phone to record).

(3) Touch the positive and negative ends of the electric field with a screwdriver to release residual electricity.

(4) Take out the electric field and filter screen, soak them in the cleaning solution for 10-20 minutes in sequence, focus on cleaning the insulators to their original color, rinse them with clean water, air dry them, install them in their original positions, and test their functions before starting to work.

(5) During the cleaning process, handle with care and prohibit deformation of the electric field electrode plate, which may cause discharge. If deformation or discharge is found, adjust the electrode plate before use.

(6) Close the maintenance door to put the equipment into normal condition.

(7) After cleaning, turn on the fan power for a few minutes before using it for the first time. Wait for the electric field to dry completely before turning on the electric field power for work.

(8) The purifier relies on an electric field to absorb oil fumes. If there is a "popping" electric shock sound when the purifier is first turned on, it is normal. Occasionally, a few sounds do not need to be adjusted. If the frequency is high, you can check whether there are large foreign objects or damaged insulators inside the purifier, and then lower the power and voltage of the purifier appropriately.
