Working Principle Of Plasma Air Disinfection Machine

The plasma air disinfection machine is an air purifier composed of antibacterial and anti-mildew filter, circulating fan, plasma electrostatic field, photoelectric catalytic technology, photocatalyst, negative ion generator and intelligent controller. What is the working principle of the plasma air disinfection machine?

1. Working principle of plasma air pre-charged dust collection:

Using an extremely uneven electric field or forming a corona discharge to generate plasma, the large number of electrons and positive and negative ions contained in the electric field will collide with the particulate pollutants in the air inelastically under the action of the electric field gradient, thereby attaching to it, making it a The charged ions are collected by the dust collector under the action of the applied electric field force.

The treatment process is divided into three stages: 1) e+M (pollutant molecules)-M-; 2) M- + SP (solid particles)-(SPM) -; 3) (SPM)--SPM ( Deposited on the dust collector). Electrostatic dust collection is a physical process. In this process, the total suspended particles (TSP) suspended in the air with a diameter of less than 100μm and the inhalable particles (PM10) with a diameter of less than μm have a high removal efficiency.

2. Working principle of plasma chemical reaction:

Through the high-frequency high-voltage pulse corona streamer discharge with steep front and narrow pulse width (nanosecond level), non-thermal plasma is obtained under normal temperature and pressure, and a large number of active particles in the plasma are used to pollute toxic, harmful and difficult-to-degrade pollution Substances are directly decomposed and removed.

It can be achieved through two ways: one is to open the chemical bonds of some harmful gas molecules under the instantaneous high energy of high-energy electrons, and make them directly decompose into elemental atoms or harmless molecules; the other is to open a large number of high-energy electrons, ions, and excited states. Particles and oxygen free radicals, hydroxyl free radicals (free genes with unpaired electrons have strong activity), etc., oxidize and decompose into harmless products.

3. Working principle of plasma air disinfection machine:

The plasma air disinfection and purification system uses a specific voltage to convert the electrons in the particulate atoms in the air into charged ions. Millions of positive ions and negative ions are formed by electric ions in the air. These ions are accurately calculated and measured, which can simulate the air environment of the natural mountainous area. In addition to making people feel fresher indoors, they can also be simulated. In addition to the natural mountainous air environment, it can also effectively solve various indoor air pollution problems. Lideng uses this independent plasma disinfection system to produce air disinfection machines that can effectively kill dust particles and pollen in the air through ionic bonds. These charged particles quickly condense into particles! Increase their size and are easily removed by the filter, reducing breathing Area of bacteria. In addition, it can quickly neutralize odors and organic pollutants that are oxidized by active oxygen molecules and are quickly eliminated. The plasma air disinfection machine can also obtain a certain amount of energy through the balanced positive and negative ion air electron pulse discharge. When the electrons collide with bacteria and mold spores, the energy transferred is the same or similar to the bond energy of the chemical bonds, breaking these bonds. As a result, bacteria and mold can no longer multiply. The plasma air disinfection machine developed by Lideng not only sterilizes bacteria, but also kills viruses and bacteria in the air more effectively. It can also remove air formaldehyde, vocal and other gases. Our common furniture and paint volatilize organic compounds, which act as ions. It is generated by collision with these volatiles to produce organic compounds, which act as activation or degradation, and jointly promote the degradation of tvoc to generate carbon dioxide and water.
