Plasma air purification equipment
Plasma air purification mechanism:
Asymmetric plasma structure is adopted to make the plasma field produce corona discharge or streamer discharge stably under certain high voltage, ionize the harmful gas molecules entering the plasma field, replace or break its basic chemical structure, completely eliminate the gas molecules, and disinfection and sterilization and decompose the bacteria and organic substances in the air

Application in Environmental Engineering:
The application of low-temperature plasma technology in exhaust gas treatment With the development of industrial economy, volatile organic waste gases generated by industries such as petroleum, pharmaceuticals, paints, printing, and coatings are also increasing. These waste gases not only stay in the atmosphere for a long time, but also spread and drift to distant places, causing serious pollution to the environment. When these waste gases are inhaled into the human body, they directly pose great harm to human health; In addition, the uncontrolled emission of industrial flue gas has led to the deterioration of the global atmospheric environment, and the harm of acid rain (mainly from industrial emissions of sulfur oxides and nitrogen oxides) has attracted the attention of various countries. Due to the pollution and acidification of the atmosphere, the ecological environment has been damaged, major disasters have occurred frequently, and enormous losses have been caused to humanity. Therefore, it is imperative to choose an economical and feasible processing method. The traditional treatment methods for degrading volatile organic pollutants (VOCs), such as absorption, adsorption, condensation, and combustion, are difficult to achieve for low concentrations of VOCs. However, photocatalytic degradation of VOCs also has the problem of catalyst deactivation. The use of low-temperature plasma treatment for VOCs is not limited by the above conditions and has potential advantages. However, plasma is an interdisciplinary field that includes fundamental disciplines such as discharge physics, discharge chemistry, chemical reaction engineering, and vacuum technology. Therefore, currently there are very few units that can maturely master this technology. Most of the promotions about using low-temperature plasma technology to treat exhaust gas are not true low-temperature plasma exhaust gas treatment technology.
The principle of low-temperature plasma technology for treating pollutants is: under the action of an external electric field, a large number of energy carrying electrons generated by dielectric discharge bombard pollutant molecules, causing ionization, dissociation, and excitation, and then triggering a series of complex physical and chemical reactions, transforming complex large molecule pollutants into simple small molecule safe substances, or transforming toxic and harmful substances into non-toxic and harmless or low toxicity and low harm substances, thereby degrading and removing pollutants. Due to the average energy of electrons generated after ionization being 10 eV, controlling the reaction conditions appropriately can make chemical reactions that are generally difficult to achieve or slow in speed very fast. As a high-tech with strong potential advantages in the field of environmental pollution treatment, plasma has received high attention from relevant disciplines both domestically and internationally.

Development and Application of High Energy Ion Technology:
The high-energy ion deodorization and purification system is a deodorization equipment designed by our company based on foreign high-tech. It can effectively treat harmful substances such as bacteria, inhalable particulate matter, sulfur compounds, VOC, etc. in exhaust gas. Its core device is the high-energy ion system, which works by emitting high-energy positive and negative ions from the ion generation device placed inside the equipment. It can come into contact with organic volatile gas molecules (VOCs) in the air, open the chemical bonds of VOC molecules, and decompose into carbon dioxide and water; It also has a decomposing effect on hydrogen sulfide and ammonia; The ion generation device emits ions that collide with dust ions and solid particles in the air, causing the particles to aggregate and form larger particles that settle down by their own gravity, achieving the purpose of purification. The emitted ions can also interact with static electricity, odors, etc. in the exhaust gas, effectively destroying the environment for bacteria to survive in the air, reducing the concentration of bacteria in the exhaust gas, and completely eliminating them.
Deodorizing equipment has filtering function: a precision filtering device installed in the suction channel separates soil particles from the air; Photoelectric detoxification function: After further photoelectric oxidation, the air solidifies the photoelectric oxidation effect;
High energy ion regulation function: By using a specialized ionization tube to increase the active oxygen content of indoor air, this process regulates and aggregates natural and healthy air ions, continuously disinfects indoor air and appliance surfaces, and effectively removes odors.
High energy ion deodorization mainly consists of gas collection system, air filter, ion generation device, fan, and exhaust gas discharge device.

High energy ion deodorization technology is mature and reliable. The deodorization system can inhibit bacterial and viral activity, eliminate odors, eliminate static electricity, reduce inhalable particulate matter in the air, increase indoor air ion concentration, and enhance air freshness. And ensure that the provided ion deodorization system does not produce ozone, has no adverse effects on human body and air, and will not cause secondary pollution.
