About the technical classification of purification equipment (2)?

1. Multi-layer filtration. It is mainly a composite purifier with good filtering effect and can significantly reduce the solid dust in the air, but the price is relatively high, and its filtering device needs to be replaced after a period of use, and it cannot be regenerated, and it has basically no effect on harmful gases. There are many consumables and high cost of use. The replaced filter element involves the difficulty of harmless disposal.

2. Catalysis and decomposition. It is mainly a photocatalyst purifier, which can decompose some harmful gases. The price is relatively low. The ultraviolet lamp is easily damaged and replaced frequently. At the same time, ultraviolet rays are harmful to the human body and plastic.
3. Filter adsorption. The hydrophobic crystalline silica molecular sieve is mainly used as the filter medium. The effect is obvious. It can completely remove benzene, xylene, chloroform and other harmful gases. It does not adsorb water and air. It can effectively adsorb a variety of harmful gases. The adsorption capacity is large. One regeneration can be used for one and a half years. The filter material can be desorbed and reused in a simple way, and no new pollution source will be generated. The life of the material is as long as ten years, so the maintenance cost is very low. It has little effect on reducing the solid dust in the air, and the cost is higher than other products.
4. NICOLER sterilization technology NICOLER originated from Greek, originally meaning "victorious people". Now it refers to a disinfection method of simultaneous operation of humans and machines on the same field: for air disinfection, people do not need to leave the disinfection place, while disinfection and sterilization Without any harm to the human body, this kind of disinfection method is called "dynamic disinfection"; because it is a successful practice of mankind to defeat natural organisms through science and technology, it is also called "NICOLER sterilization technology".
NICOLER sterilization technology is based on the actual characteristics of high humidity, high temperature and high peculiar smell in the production workshop, and adopts the latest NICOLER three-level two-way plasma electrostatic field working principle. The sterilization process is: the plasma electrostatic field is generated by high-voltage direct current pulses to produce a reverse electrical effect. Generate a large amount of plasma. Under the action of the negative pressure fan, the negatively charged bacteria are killed and decomposed when the polluted air passes through the plasma electrostatic field, so that the controlled environment is maintained at the "sterile and dust-free" standard. Since people can work in the workshop at the same time when disinfecting the workshop, this kind of disinfection machine is called "NICOLER dynamic disinfection machine". This machine is an advanced disinfection equipment that does no harm to the human body. It is mainly used for simultaneous dynamic disinfection and disinfection when people are working; it can kill and decompose more than 300 gaseous pollutants in the room, such as formaldehyde, radon, ammonia, benzene Series and other radioactive objects and inhalable particles, as well as various bacteria and viruses. Eliminate all kinds of strange smells and dust in the air caused by decoration, including cigarette smoke. No harm to the human body.
