Introduction to the principle of a common household air purifier

With the concern of more and more people about indoor air pollution, household air purifiers have begun to be recognized by more and more families, so the air purifier really works? The following small series talk about air purifiers The principle.

A typical air purifier consists of a high voltage circuit, a negative ion generator, a micro fan, an air filter, and the like. Mainly adopts infrared remote control, gap operation, and other control methods. The filter forms are a mechanical, electrostatic and mechanical electrostatic hybrid.

There are two forms of high voltage generating circuits: one is 220V mains direct boost, double voltage rectification. The other is that the mains is stepped down and rectified by the transformer to form a low-voltage direct current, and then self-excited, boosted, rectified, and filtered to form a DC high voltage. Both forms of circuit generate high voltages between kilovolts and tens of thousands of volts. The charged dust is sucked onto the positively charged electrode plate repair network by discharging the needle electrode. The air filter adsorbs odor with activated carbon or fluorenone, and filters out harmful substances in the air. The negative ion discharge electrode is a set of needle-shaped metal bodies. After the power is turned on, the DC high voltage generated by the high voltage circuit continuously ionizes the air, generating a large amount of positive and negative ions. Since the needle-shaped emitter has negative high pressure, it absorbs positive ions, and a large number of negative ions are repelled by the negative high pressure and are blown out by the micro fan to form a negative ion wind, thereby purifying the air.

Olansi is a professional enterprise specializing in indoor air treatment. The company recommends that the owners do not blindly choose the top 10 home air purifiers after the renovation of the new house. You should find a professional testing company to test the indoors. If the test results show indoors after the test is completed, If the formaldehyde exceeds the standard, then the staff of Olansi will be asked to carry out indoor pollution control. Olansi has a professional management team. After the treatment, the indoor air can reach the standard of human health breathing, and at the same time, it can achieve one-time treatment without adding pollution sources. , for the benefit of life.
