How to use static electricity to purify the air, how to remove static electricity from the air

Electrostatic adsorption (electronic) air purifier principle.

The main component of the electrostatic adsorption (electronic) air purifier is the electrostatic adsorption device.

The core component of an electrostatic adsorption air purifier is an electrostatic adsorption device (also known as a high-voltage electrostatic field). The electrostatic adsorption device is composed of a discharge wire and a negative plate. Under the action of the high-voltage generator, the electrostatic adsorption device can generate a DC high-voltage voltage of 4kv-8kv, and form a strong electrostatic field inside the electrostatic adsorption device.

When indoor air passes through an electrostatic adsorption device, airborne particulate matter, including microorganisms, is forced to take on a positive charge and adsorb onto the negative plate. At the test check-in, the electrostatic adsorption device is able to capture particles with a diameter of . Electrostatic adsorption air purifier is one of the most common air purifiers in China.

There are two main types of electrostatic adsorption devices commonly used at home and abroad, namely two-stage precipitator and beehived electrostatic dust collector.

The two-stage electrostatic adsorption device is the most commonly used excellent electrostatic adsorption device in the world, and its advantage is that it not only improves the efficiency of sterilization and dust collection, but also is easy to clean. At present, the two-stage electrostatic adsorption device is favored by domestic air purifier manufacturers.

Honeycomb electrostatic adsorption device is the most commonly used electrostatic adsorption device for domestic air purifier manufacturers. It is characterized by a relatively simple process and the use of a "honeycomb" to increase the area of the negative plate. The biggest disadvantages of honeycomb electrostatic adsorption devices are poor dust collection efficiency, difficult cleaning and large amounts of ozone.

An electrostatic adsorption device is actually a type of electrical filter. The advantages (PROS) of electrostatic adsorption devices are (1) relatively low resistance (2) and can be used repeatedly after cleaning. The disadvantages (cons) of electrostatic adsorption devices are (1) they must be cleaned regularly, otherwise their dust collection efficiency will be significantly reduced.

2) Electrostatic adsorption devices use high-voltage discharge, which undoubtedly produces ozone.

Most of the dust in the air is colloidal and has an electric charge, and the electrostatic precipitator can release an electric charge opposite to the charge carried by the colloid, neutralize the electrical properties of the colloid, make it settle, no longer float in the air, and easy to clean.

The principle of opposite-sex attraction of electric charges.

Let the charged material particles rush to and adsorb to the field source under the action of the electric field force.

Method: When the relative humidity of the air is lower than 35%, it is easy to rub and generate static electricity, at this time, if the relative humidity of the room rises to 45%, it is difficult to generate static electricity. Therefore, when the weather is particularly dry, sprinkle some water at home, place a basin or two of clean water, or use a humidifier to reduce static electricity.

Ways to reduce the harm of static electricity to people:

1. When the TV is working, electrostatic particles will be generated around the screen, and these particles will absorb a large amount of floating dust in the air, and these charged floating dust will have a negative impact on the human body. Therefore, the TV should not be placed in the bedroom, the window should be opened when watching TV, and it should be 2 to 3 meters away from the screen, and you should wash your hands and face after watching the TV in the hall.

2. Bathing and changing clothes frequently can effectively eliminate the electric charge and charged dust accumulated on the surface of the human body.

3. Barefoot is conducive to the release of static electricity gathered on the surface of the body, so don't let go of all opportunities to be barefoot when resting. If you don't have the opportunity or can't hide your feet, you can nail a staple-shaped copper wire to the slippers and thread them straight through the soles of your shoes, so that when you walk, you can release the static electricity that has accumulated in your body.

Ways to release static electricity:

1. Pay attention to body moisturization. In winter, the temperature and humidity are low, and it becomes dry, and it is easy to generate static electricity after friction. You can strengthen moisturizing, moisturizing** by applying body lotion and hand cream in a timely manner every day to prevent static electricity from accumulating.

2. Increase indoor humidity, you can place a humidifier, one or two basins of water or anti-static spray in the room, so that the dry air becomes moist, reduces the possibility of static electricity, and can also keep the humidity in the state.

3. "Discharge" in advance. In order to prevent being electrified, you can first grasp the wider metal key head or other small metal devices with your hands, and then use the key tip to touch the metal doors and windows, and "let go" the electricity on your body in advance, so that you can rest assured that you can open the door and window with your hands. When you touch things and people with your fingertips, you will have a noticeable tingling sensation at the moment when static electricity is generated, and this is because the contact area is small, so the pain is more obvious.

In this regard, the contact area can be increased, such as extending the entire palm of the hand to touch, so that the discomfort will be reduced.

4. Choose clothing fabrics that are not easy to generate static electricity. When the climate is dry, chemical fiber clothes and sweaters will produce static electricity due to friction when putting on and taking off, and chemical fiber materials may also cause itching. Common chemical fiber materials include polyester fiber, polyester, acrylic fiber, etc.

Therefore, winter clothes (especially underwear), household items, etc., try to choose pure cotton, linen, silk or other anti-static materials, and it is best to be loose and gentle.

5. Use fabric softener. You can also add some fabric softener when washing clothes, which not only makes the clothes soft and smooth, but also reduces static electricity.

6. Do not use plastic combs. Plastic combs are easy to rub against the hair to produce static electricity, and in winter, you can use a wide-toothed wooden comb, corner comb, etc., or sprinkle some water directly on the comb and hair, which can reduce the static electricity and knots in the hair.

There are many ways to remove static electricity from clothing, because static electricity tends to occur in a relatively dry environment, and if you can make the air around your clothes moister, it can naturally eliminate static electricity. Here are a few simple ways to do this.

1. If you have more time, you can wash the clothes, so that the static electricity on the clothes can be removed with water.

2. In the case of time urgency, you can use a clean wet towel to gently wipe your clothes.

3. Put your clothes near the humidifier for a while.

In addition, hanging the garment on metal that is in contact with the earth can also eliminate static electricity on the garment, because the static electricity on the garment can be introduced to the ground through the metal.
