Description

Plasma air purifier

Technical Field

The utility model relates to a plasma generator and air purification field, in particular to plasma air purifier.

Background

An air purifier using a plasma generator is a more advanced air purifying apparatus. The plasma purification technology utilizes high-voltage discharge to ionize air to generate a large amount of electrons and ions, and the energy generated by mutual collision and annihilation of the positive ions and the negative ions can decompose germs in the air to achieve the sterilization effect. Meanwhile, a large amount of free radicals such as OH and O excited in the discharging process can further react with harmful organic molecules such as formaldehyde SO2 and NO2 to decompose pollutants. In addition, the particles with different charges in the air attract each other, and the particles can be changed into larger particles from small particles, so that the particles are converted into dust fall, and the dust removal requirement is met.

In the existing plasma air purification technology, the effective reaction volume of air and a plasma field is the key for determining the purification efficiency of the plasma technology. In the discharge technique provided in the patent (202010713290.X), charged particles can diffuse around under the action of the repulsion force of like charges, the positive and negative ion emitting ends are separated by a certain distance, and the positive and negative ions can fully react with ambient air with the help of the air flow in the direction perpendicular to the connecting line of the bipolar emitting ends. However, in this technique, the resistance created by the air flow, despite the considerable separation between the bipolar emitters, does not completely prevent the positive and negative ions from attracting each other under the influence of the electric field. Therefore for reducing the probability that positive and negative ions will be neutralized and annihilated before meeting with the pollutant, the utility model provides a simple structure can effectively increase air and plasma reaction volume, avoids the plasma air purifier that positive and negative ions are compound in advance.

Meanwhile, suspended particles in the air can be mutually attracted by adsorbing positive and negative ions, and are accumulated and settled, so that the air purification effect is achieved.

The plasma generation module 3 in this embodiment includes a positive ion releaser 3-1 and a negative ion releaser 3-2, and the positive ion releaser 3-1 and the negative ion releaser 3-2 are both installed on the high voltage transformer 4 at the bottom of the plasma generation module 3 and are respectively communicated with the positive pole and the negative pole of the power supply.
