Supply ZLB series low humidity dehumidification unit rotary dehumidifier industrial dehumidifier

The working principle of the rotary dehumidifier
:
: The dehumidification rotor is made of ceramic fiber paper with a temperature resistance of
: ℃ or above, which is formed into a honeycomb-shaped rotor through a molding machine. It is obtained by coating silica gel between ceramic fibers, so the dehumidification wheel will not cause problems such as burning and deliquescence. Since its dehumidification function uses physical effects rather than chemical effects, it does not produce any harmful chemicals.

:
: The dehumidification principle of the rotary dehumidifier is to use silica gel coated on the rotary wheel to physically adsorb the moisture in the air to the porous synthetic silica gel. , and then in the runner regeneration area, the water vapor adsorbed in the silica gel holes is heated and vaporized, and reaches the entrance of the AC heat exchanger to form high-temperature and high-humidity air, and then passes through the heat exchanger that has been cooled by the indoor cold and humid air. When the dew point difference occurs, condensate is discharged.

: Overview of air dehumidification: If the constant temperature and humidity system is a combined unit, it usually has a fresh air cooling and a rotor dehumidification section. When the processed air is cleaned by the fresh air filter, it contacts the surface of the surface cooler in the fresh air surface cooling section. Since the surface temperature of the fresh air surface cooler is lower than the temperature of the air, the air is cooled and the temperature decreases. At the same time, the moisture in the air It turns into condensed water and is discharged through the condensate pipe. After the temperature and moisture content of the air are reduced, the runner performs adsorption and dehumidification to meet the low humidity requirements. Finally, all the air is passed through the rear surface cooler or heater. The temperature is controlled, and the process air with temperature and humidity that meets the requirements is sent out by the air blower.

: Principle of cooling and dehumidification:

: Because the air can hold different amounts of moisture at different temperatures and energies. , the moisture content in the air decreases as the air temperature decreases. When the outdoor air passes through the fresh air surface cooler, the air is cooled by the surface cooling coil. As the temperature of the air decreases, the water vapor in the air gradually condenses and reaches a saturated state. When the dew point of the air continues to decrease, the center of the air The water vapor becomes condensed water and precipitates, so that the absolute moisture content in the air is reduced, and the air realizes the dehumidification process.

: The dehumidification principle of the adsorption wheel:

: The dehumidification wheel is divided into a processing area and a regeneration area by a sealing system inside the dehumidification section. The wheel rotates slowly at a speed of

: turn
/
: hours to ensure that the entire dehumidification is a continuous process. When the treatment air passes through the treatment area of the runner, the water vapor in it is adsorbed by the hygroscopic medium in the runner. The water vapor undergoes phase change at the same time and releases latent heat. The runner also gradually tends to absorb a certain amount of moisture. At this time, the treatment air becomes dry and hot air due to the reduction of its own moisture and the release of latent heat. At the same time, in the regeneration area, the other air passes through the regeneration heater first, becomes high-temperature air (usually
: degrees) and passes through the saturated runner after absorbing moisture, causing the adsorbed moisture in the runner to evaporate , thereby restoring the dehumidification ability of the runner. At the same time, after the regeneration air becomes humid air due to the evaporation of water, the humid air is discharged to the outdoors through the regeneration fan.

: As a rotary adsorption dehumidifier, its most important core component is the dehumidification rotor. The rotor is made of glass fiber and heat-resistant ceramic materials as the internal support carrier of the rotor. It is specially designed It is synthesized from high-efficiency hygroscopic media materials (such as high-efficiency silica gel). In this way, the high-efficiency hygroscopic agent and the special honeycomb structure of the runner itself not only ensure the huge surface area of the runner in contact with the air, but also improve the moisture absorption efficiency of the runner and increase the moisture absorption capacity. The runner can be cleaned by gas purging to remove the runner's moisture. Some mechanical pollutants on the wheel surface, such as dust, oil, etc.

: Advantages of combined dehumidification
::

: In the case of high temperature and high humidity in summer, the humidity load is the largest: at this time, the humidity The load is carried by two processing sections at the same time. First, the fresh air surface cooler takes full advantage of its high dehumidification efficiency and large dehumidification capacity under high temperature and high humidity conditions to remove most of the moisture in the air and reduce the temperature of the air. When the refrigeration dehumidification efficiency decreases, the air humidity is then dehumidified through the rotor to make the air humidity meet the low humidity control requirements: In this way, the system makes full use of the advantages of the two dehumidification methods. In other seasons, such as spring and autumn, due to the decrease in moisture load, at this time, the energy adjustment of the refrigeration system is used to control the air temperature after front cooling, and the moisture load is completely borne by the dehumidification runner section. The purpose of system post-cooling and heating is to accurately control the supply air temperature.

: Things to note when purchasing a dehumidifier:

: Since combined dehumidifiers involve many technical aspects, the selection of each component and the overall Only by having a comprehensive understanding of on-site applications can we design and produce reliable products. Nowadays, some manufacturers only focus on order production and lack corresponding technical personnel, resulting in a large number of flashy products flooding the market. Some so-called Due to the fierce market competition in recent years, old manufacturers have relied on their good reputation and customers' lack of understanding of their products to sacrifice product quality and do everything possible to save costs by using low-cost substandard materials and substandard products without reducing their original profits. Haolai deceives customers. Supply B series low humidity dehumidification unit rotary dehumidifier industrial dehumidifier

: Therefore, customers must fully understand the technical performance, product configuration and manufacturer's capabilities of the rotary dehumidifier before purchasing, and contact professional technical personnel Only by communicating can you choose a cost-effective product! ! !
