Dehumidification Principle of Air Treatment
The system utilizes a dehumidification rotor with a honeycomb structure as shown in the diagram, where the drive motor rotates the dehumidification rotor 8 to 18 times per hour, continuously repeating the moisture-absorbing and regenerating action, thus providing dry air.
The rotor is divided into a moisture absorption zone and a regeneration zone. After the moisture in the air is removed in the moisture absorption zone, the blower sends the dried air into the room.
The absorbed moisture rotor moves to the regeneration zone, when the regeneration air (warm air) sent in from the opposite direction will drive out the moisture, so that the rotor continues to work.
The air for regeneration is heated by steam, natural gas, gas, gas, oil, electricity and other devices.
Because of the special performance of American Eco-Fresh CS series full-heat rotor, Jin Cai Sheng series dehumidifier can continuously dehumidify the air at a very large air volume, and it can reach the requirement of very low moisture content. After the matching combination, the humidity content of the treated air can be lower than 0.0007g/kg
If you want the temperature of the dry air to remain stable, you can cool or heat the air at the outlet of the dehumidifier by installing a cooling device or a heater.
Features of air treatment
The troubles caused by moisture on products in the process of product manufacturing bother human beings all the time. Application of solid adsorbent for moisture absorption in the process of simultaneous regeneration and dehydration of the adsorbent after moisture absorption, so that the solid adsorbent recycling, the entire moisture absorption work can be carried out continuously. Overcome the static solid adsorption can not be continuous dehumidification and refrigeration condensation dehumidification in low temperature and low humidity can not help the shortcomings. Can play its low temperature and low humidity conditions can be continuous and stable, large dehumidification characteristics. Jin Cai Sheng company's rotary dehumidifier is the application of this advanced technology developed, with special features that can not be. Rotary dehumidifier, compared with other dehumidification methods, has its own unique characteristics;
Can simply obtain dry air with ultra-low humidity.
Can continuously provide dry air with ultra-low humidity with dew point below 6℃, which cannot be realized by cooling dehumidification method, at low cost.
Simple operation and maintenance.
Operation is very simple because the structure is simple and the drive unit is simple, and dry air can be obtained by operating only the dehumidifying rotor, the heater for regeneration, and the air supply fan. In addition, it is a dry dehumidification type that does not require the replenishment of hygroscopic agent, and it is easy to maintain, and the cost of operation and maintenance is low.
Superior durability performance.
In a clean air environment, the performance of the dehumidifying rotor hardly decreases or deteriorates, and it is capable of continuous operation for many years.
A full range of machines.
From the standard model for general use to the low-humidity model that produces dry air with ultra-low humidity, we have a wide range of machines that can be used in a variety of conditions.
Non-polluting green machine due to the use of the U.S. Eco-Fresh CS series of full-heat rotor molecular sieve hygroscopic agent, so the dehumidifier in the use of the process of safety, environmental protection, clean, non-fugitive dust and non-corrosive effect, but also sterilizers, pharmaceuticals, food, biochemical and other industries is particularly applicable.
1, the manufacture of dehumidification rotor is made of aluminum inorganic fiber substrate with a temperature resistance of more than 300 ℃, through the molding machine made of honeycomb-shaped rotor, and then coated with silica gel in the aluminum and only on the dehumidification rotor will not occur combustion and humidity and other issues. Since the dehumidification function is based on physical action rather than chemical action, it does not produce any harmful chemicals.
2, rotor dehumidifier dehumidification principle is the use of coated silica gel on the rotor will be in the air in the physical way of water adsorption in a porous synthetic silica gel, and then in the regeneration area of the rotor, adsorbed in the silica gel holes in the heating of water vaporization to the entrance to the AC heat exchanger, the formation of high temperature and high humidity of air, and then through the indoor cold and humid air cooling cooling heat exchanger, the dew point difference of condensate, the dew point difference of condensate. Because of the difference in dew point and condensate discharge.
Air dehumidification overview: constant temperature and humidity system such as a combination of units, usually with fresh air cooling and rotor dehumidification section. When the processed air after fresh air filter clean, in the fresh air table cooling section and table cooler surface contact, due to the surface temperature of the new air table cooler is lower than the temperature of the air, so the air is cooled, the temperature is lowered; at the same time, the water in the air into condensate precipitation, and by the condensate pipe exclusion, the temperature of the air and the water content have been lowered; after that, then adsorption dehumidification by the rotor, in order to achieve the requirements of the low humidity; Finally, all the air is then controlled by the rear surface cooler or heater to control the temperature, and the process air with the required temperature and humidity is sent out by the air blower.
2, cooling dehumidification principle:
Because of the air at different temperatures and energy, the air can hold different moisture, the moisture content of the air as the air temperature decreases and decreases. When the outdoor air through the new air table cooler, the air is cooled by the table cooling coil cooling, air with the lowering of the temperature, the water vapor in the air gradually condenses and reaches saturation, when the dew point of the air continues to decrease, the water vapor in the air becomes condensate and precipitation, so that the absolute moisture content of the air is reduced, the air to achieve the dehumidification process.
3, adsorption rotor dehumidification principle:
Dehumidification rotor in the dehumidification section of the internal sealing system is divided into the processing area and regeneration area, dehumidification rotor to 8-10 rpm speed of slow rotation to ensure that the entire dehumidification for a continuous process. When the processed air through the processing area of the rotor, the water vapor is adsorbed by the hygroscopic medium in the rotor, the water vapor phase change occurs at the same time, and the release of latent heat, the rotor is also due to absorb a certain amount of moisture and gradually saturated; at this time, the processed air due to its own water reduction and latent heat release and become dry, hot air. At the same time, in the regeneration area, the other air first through the regeneration heater, into a high-temperature air (generally 100-140 degrees) and through the saturated rotor after the moisture absorption, so that the water adsorbed in the rotor has been evaporated, thus restoring the dehumidification capacity of the rotor; at the same time, regeneration of air due to the evaporation of water into the wet air; after that, through the regeneration of the fan will be discharged to the outdoor wet air.
As a rotor adsorption dehumidifier, its main core component is the dehumidification rotor, the rotor is made of glass fibers and heat-resistant ceramic materials as the rotor's internal support carrier, and a special effect of moisture absorption media materials (such as high-efficiency silica gel) and the synthesis. In this way, the high efficiency moisture absorption agent and the special honeycomb structure of the rotor itself, not only to ensure that the rotor and air contact with a huge surface area, but also to improve the moisture absorption efficiency of the rotor to increase the moisture absorption capacity; the rotor can be cleaned through the gas blowing, in order to remove some mechanical contaminants on the surface of the rotor, such as dust, oil and so on.
4, the advantages of combined dehumidification:
In the summer high temperature and high humidity, the wet load is the largest: at this time, the wet load of two processing sections at the same time, first give full play to the new air table cooler in the high temperature and high humidity conditions of high dehumidification efficiency, dehumidification, remove most of the water in the air, and reduce the temperature of the air; and when the efficiency of the freezing and dehumidification is reduced, and then after the When the efficiency of refrigeration dehumidification drops, then through the rotor dehumidification, so that the air humidity to reach the requirements of low humidity control; thus, the system makes full use of the advantages of the two dehumidification methods. In other seasons, such as spring and fall, due to the wet load drop, at this time, through the refrigeration system of energy regulation, control the air temperature after the front cooling, wet load completely by the dehumidification of the rotor section. The purpose of the system after cooling and heating is to accurately control the temperature of the air supply.
5, the purchase of dehumidifiers need to pay attention to:
Because the combined dehumidifier involves more technical aspects of the selection of the various components and the application of the entire site should have a comprehensive understanding of the design and production of reliable products, and now some manufacturers are only to take orders, the production is based on the lack of appropriate technical personnel, resulting in a large number of flashy products flood the market, some of the so-called old manufacturers because of the order, the production of the main lack of appropriate technical staff, resulting in a large number of products, but not real! Market, some of the so-called old manufacturers due to fierce competition in the market in recent years, by virtue of the original establishment of a good reputation, the use of customers do not understand the product, in do not want to reduce the original profit, at the expense of product quality, and do everything possible to save costs and the use of low-cost unqualified materials, substandard to deceive customers.
So customers should fully understand the technical performance of the rotor dehumidifier before purchasing, product configuration and manufacturer's ability to communicate with professional and technical personnel in order to choose the cost-effective products!
