Overview

Adsorption rotary dehumidifier is recognized as one of the preferred technologies to replace CFC's compression refrigeration dehumidification in the twentieth century due to its significant energy saving and environmental protection advantages. The rotary dehumidifier can quickly, simply and effectively reduce the air humidity, and effectively solve the dehumidification fields such as normal temperature and low humidity, low temperature and low humidity that cannot be achieved by other refrigeration methods, especially the air dew point can reach -70°C after combined treatment The following: and can use industrial waste heat, waste heat, solar energy, natural gas and other low-grade thermal energy as renewable energy, no environmental pollution, low energy consumption.

Widely used in food, medicine, electronics, electrical appliances, chemical industry, national defense, printing and other industries with humidity requirements. In areas with high temperature and high humidity, the adsorption rotary dehumidifier will exert its unique advantages and bring huge economic benefits to enterprises.

The working principle of dehumidifier rotor adsorption and desorption

Dehumidifying Wheel

"Fengxing" dehumidifier adopts a world-class patented high-efficiency runner; the runner adopts a patented technology: with an inorganic binder, the glass fiber is processed into a honeycomb Under high temperature combustion, all organic substances are transferred, and then the runner of the honeycomb matrix is ​​fused with special silica gel (metal silicate) through a polymerization reaction, so it not only has good heat resistance, but also can be applied under any humidity conditions ; Strong dehumidification ability, no dehumidifier loss, non-toxic, non-corrosive, ensuring long-term safe and stable operation; because the runner increases hydrophilic groups and micropores to absorb more water, according to air conditions , the drying capacity is 20% ~ 30% higher than other silica gel runners.

The molecular sieve rotor uses special synthetic zeolite as hygroscopic agent to implant into the glass fiber matrix. Because zeolite has small pores and strong heat resistance, this rotor is suitable for Low dew point conditions, or used to treat air containing volatile organic compounds such as ethylene glycol, acetaldehyde, etc.; regeneration air up to 220°C can be used for runners, and all runners are basically free of polymerization; this rotation The wheel is made of special synthetic zeolite crystallized on glass fiber through a special chemical reaction. According to the air flow conditions, a single wheel can reach -80°C D.P.

Basic structure and working principle of dehumidifier

The core component of the rotary dehumidifier is a honeycomb runner, which is composed of a special ceramic fiber carrier and active silica gel; the two sides of the runner are made of special sealing devices Divided into two areas: treatment area and regeneration area.

When the humid air that needs to be dehumidified passes through the treatment area of ​​the runner, the water vapor of the humid air is adsorbed by the active silica gel of the runner, and the dry air is sent to the treatment area by the treatment fan. The runner that rotates slowly and carries saturated water vapor enters the regeneration area; the high-temperature air blown in the reverse direction in the regeneration area causes the water adsorbed in the runner to be desorbed and discharged to the outside by the fan, thereby The runner restores the ability to absorb moisture to complete the regeneration process.

The wheel rotates continuously, and the above-mentioned dehumidification and regeneration are carried out over and over again, so as to ensure the continuous and stable dehumidification state of the dehumidifier.

VOC organic solvent recovery unit FXV

Fengxing Environment NMP recycling system: The battery has stricter requirements for the dehumidification system, and also puts forward new requirements for the NMP recycling system. NMP-methylpyrrolidone, whose boiling point is 200C, is widely used as an organic solvent in the lithium battery manufacturing industry due to its high flash point and good safety.

The NMP recovery device developed by Fenghang Company combines cooling condensation technology and rotor adsorption technology to realize continuous NMP solvent recovery and air purification. The equipment is compact and reliable in operation; NMP can be recovered by combining common circulating cooling water and chilled water according to different requirements of users; NMP can also be recovered by combining common circulating cooling water and chilled water with recovery runners. The hydrophobic molecular sieve runner selected in the equipment has excellent adsorption performance, which is conducive to the concentration of NMP in the recovery process and improves the recovery efficiency; and is conducive to the humidity control of the drying air of the coating oven.

Fengxing Environmental NMP recovery system has reasonable process and reliable operation, and the concentration discharged into the atmosphere can reach 20 PPM, or even less than 10 PPM.

Fengxing Environment NMP recycling system has four main functions:

1. Recycling the exhaust heat of the coating machine;

2. Recycle and recycle NMP in the exhaust air of the coating machine;

Third, it is beneficial to the humidity control of the drying air of the coating oven.

Fourth, the amount of exhaust gas discharged is small and meets the requirements of environmental protection.

Application scene field: organic solvent NMP waste gas recovery system applied to new energy lithium battery pole piece coating process.

VOC is the English abbreviation of volatile organic compounds (volatile organic compounds). After SO2 and Freon, the pollution of volatile organic compounds (hereinafter referred to as VOC) has become another concern of all countries in the world. One focus, most VOCs are toxic and will cause people to suffer from cumulative respiratory diseases. Under the sudden action of high concentrations, sometimes acute poisoning or even death may occur. Some VOCs can cause cancer.

Most VOCsBoth are flammable and explosive, and are prone to fire or explosion when they are discharged at high concentrations. VOCs have become a worldwide public hazard. Developed countries continue to amend laws and repeatedly reduce the emission concentration of VOCs.

Special reminder to users: 

• Using a microcomputer-controlled dehumidifier, the humidity sensor is a precision instrument. Using it in an environment with strong corrosive gas and large dust will cause the instrument to malfunction.
• Before using the dehumidifier, please read the manual carefully to avoid damage to the dehumidifier caused by improper operation.
• This machine does not have explosion-proof and anti-corrosion functions, and it is strictly prohibited to use it in environments with special requirements such as flammable, explosive gas, dust, chemical products, and biological products.
• The power supply of the machine must be grounded and protected by a circuit breaker with a 220V/50HZ AC power supply (380V/50HZ for CD industrial series dehumidifiers) The power cord must match the power of the machine,
• The rated current of the fuse is set according to the requirements of the user manual.
• The machine should be rested regularly when the machine is running for a long time. The machine should clean the filter screen regularly. If the dehumidifier is not used for a long time, it should be well protected from moisture and dust.
