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, which exist 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.

4.6There is no need for high-voltage power lines to connect between the electric field and the power source, which enables power on and power-off when closing the door, making it easy to maintain and clean.
4.7Low resistance, low noise, low energy consumption, high reliability, and high removal rate, Realize low altitude emissions.

5Typical Process Flow Diagram

Note:1.According to the inlet temperature of the exhaust gas, if the temperature is60Condensation cooling measures need to be taken first if the temperature is above.

2.If there is only oil mist in the exhaust gas and no other dust, acidic gases, or soluble pollutants, they can be omittedspray towerAnd dehydrator.

6Installation precautions

6.1Check whether the mating surfaces of the box are sealed properly.

6.2Remove shock-absorbing fillers and other debris during transportation. The electric field body must be placed on the corresponding guide rail.

6.3The positive electric field, load body, and high-voltage input terminal should have good contact.

6.4When positioning the box, attention should be paid to leaving sufficient space for the opening and closing of the electric field compartment door and power box door (this space should be able to ensure the removal of the electric field and power supply), in order to facilitate the installation and maintenance of the electric field.

6.5The grounding bolt of the box should be greater than6mm² Connect the wire to the grounding body to ensure safety.

6.6The purification equipment must work synchronously with the corresponding induced draft fan.

6.7Pay attention to distinguishing the air inlet and outlet of the equipment.

7Operation and usage instructions

7.1Check before powering on

7.1.1Power supply inspection

(1)Confirm that the input power is AC220V50Hz.

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

7.1.2Electric 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 and use

7.2.1 After checking for accuracy before powering on, turn on the power and start the purifier.

7.2.2After being powered on, the purifier should emit a continuous and stable static discharge sound, with the red light on the panel indicating power and the green light indicating operation. The green indicator light is on, indicating that the purifier has entered normal working mode.

7.2.3If both the red and green indicator lights are not on, it means that the power supply is not connected. First, check whether the power supply and wiring are working properly.

7.2.4If 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

9Maintenance and upkeep:

In order to ensure the purification efficiency of the purifier, the maintenance cycle of industrial oil fume purification equipment is set at 30 days (subject to special circumstances)

9.1Cleaning method:

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

Method 2: Prepare the required cleaning solution in a 1:10 ratio using industrial caustic soda and 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.

9.2Cleaning 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.
