Ultrasonic Humidifier

Ultrasonic Humidifier



When the air is very dry, our skin will crack. In this case, we need to increase the humidity of the air and maintain a moist environment to improve. The humidifier is the best choice. The ultrasonic humidifier mainly uses high-frequency oscillation, and then the high-frequency vibration of the atomizing piece causes the water in the humidifier to be thrown away from the water surface to produce a floating water mist to achieve the purpose of humidifying the air. Generally, the humidifier has an auxiliary function of softening water humidity display. For the water softener in the humidifier, the water passing through the water softener should not exceed 100 mg/L, and the water humidity is specified in the range of 30%-70%.


Humidification principle

Using high-frequency oscillation (oscillation frequency of 1.7MHz, exceeding the human hearing range), the high-frequency resonance of the atomizing sheet throws water away from the water surface to produce a natural and elegant water mist.


One is the amount of humidification. This is the most important parameter of the humidifier. Some enterprises cater to consumers' pursuit of large humidification, and arbitrarily mark the amount of humidification. Therefore, the standard strictly stipulates that the humidification amount should not be lower than the nominal value of the product's rated humidification amount.


The second is humidification efficiency. Refers to the ratio of the actual humidification amount of the humidifier to the input power, which reflects how much humidification the unit power consumption can produce. It is an important indicator to measure the performance of the humidifier. In order to guide consumers to purchase energy-saving and environmentally-friendly products and to promote the development of more efficient products, the standard is divided into four levels: A, B, C, and D.


The third is noise. Considering that the humidifier may be used in the bedroom, if the noise is too large, it will have a certain impact on the consumer, so the standard imposes strict limits on the noise index.


The fourth is the life of the evaporation core. For direct evaporative humidifiers, the evaporating core is the component that has the greatest impact on performance. As the humidifier continues to be used, the efficiency of the evaporation core will continue to decrease and the amount of humidification will continue to decrease. The standard stipulates that when the humidifier's humidification amount is reduced to 50% of the initial humidification amount, it is regarded as the evaporation core failure. For replaceable evaporation cores, the service life should be no less than 1000 hours.


The fifth is that many humidifiers have auxiliary functions such as softened water and humidity display. In order to prevent certain products from obviously having this function, or this function can not achieve the corresponding effect, the consumers are misled by false propaganda. The standard also puts specific requirements on these auxiliary functions: for water softeners, the standard specifies that the hardness of water should not exceed 100 mg/L after softening by a water softener. Before the water softener fails, the total amount of softened water should not be less than 100L. For the humidity display, it is stipulated that the relative humidity should be within the range of 30% to 70%, and the humidity display error should be within ±10%, so as to avoid the error being too large and misleading to consumers. In addition, the standard also stipulates that since the water level will have a significant impact on the performance of certain humidifiers, the humidifier should have a water level protection function to prevent consumers from ignoring the humidifier for a long period of time with low performance and low efficiency working status.

12. The overall design of the equipment has been tested repeatedly and tested for many years. It has a compact structure and reasonable matching. There is no high-power motor. It is not driven by pure mechanical energy. Therefore, there is no noise during operation and high atomization effect on liquid.


Advantages and disadvantages

The utility model has the advantages of small volume, large humidification intensity, small power consumption, good control performance, small and uniform fog particles, possible bacteria, high unit price and short service life; and certain requirements for water quality.


Selection Guide

1. The ultrasonic humidifier control parameters are humidification capacity, voltage and input power.


2. Features of ultrasonic humidifier:

Compact structure, convenient installation, sensitive control, high efficiency and energy saving, compared with electrode (hot) humidifier, can save energy by 70%~85%.


3. The power consumption of the ultrasonic humidifier is much lower than that of the electrode (hot) humidifier, but the electrode (hot) humidifier is isothermal humidification, and the ultrasonic humidifier is equal humidification. Therefore, the air humidified by the ultrasonic humidifier also needs to be heated and heated. Therefore, if the humidification efficiency of the two is the same, the ultrasonic humidifier saves electricity but does not save energy from the viewpoint of energy consumption.


4. The actual frequency of the ultrasonic humidifier tends to shift, which reduces the humidification capacity. When selecting a humidifier, an additional 10% to 20% safety margin should be considered.


5. As the water temperature increases, the humidifying capacity of the humidifier increases. However, as the water temperature increases, the life of the humidifier will decrease. Generally, the water temperature should not be higher than 35 °C.

Applications

Tobacco leaves are highly hygroscopic materials - that is, they are greatly affected by changes in the humidity of the surrounding air. If the relative humidity of the surrounding environment is low, the air will absorb moisture from the tobacco leaves, causing the leaves to dry and affecting the leaves. quality. According to the standards of the tobacco industry, when the tobacco leaves are stored in the alcoholic storage, the water content is 16%-18%, and the tobacco leaves after the alcoholization are unpacked, decomposed, and the leaves are selected to enter the threshing and re-roiling line for production. In the process of unpacking, unwinding, and selecting leaves, the tobacco leaves are easily broken due to the loss of moisture in the tobacco leaves due to operations such as smoking, handling, and grading. It not only reduces the quality of the tobacco leaves, but also causes economic losses, and increases the dustiness of the workshop, resulting in deterioration of the production environment. The dust floats in the air, and the smell of smoke leaves affects the smell and breathing of the workers in the workshop. Dust is not only a troublesome cleaning and cleaning, but also the most common carrier for many microorganisms. A variety of pollutions such as irritating soot, dust, carbon dioxide in the air, and various microorganisms attached to the dust are inhaled by workers, which can cause and aggravate chronic bronchitis, pneumonia, and affect workers' health.

Higher relative humidity (above 50%) can sink dust in the air. Because the surface of the dust in the air has a positive charge, the surface of the atomized water particles has a negative charge. The contact of positive and negative charges causes the volume of smoke and dust floating in the air to expand and expand, accelerating the precipitation of dust. It can effectively remove various harmful substances such as nicotine, formaldehyde, carbon monoxide and bacteria, as well as various defects such as paint mites, mildew, soot and odor, and make the air fresher. During the process of water atomization, a large amount of negative ions are released. The high concentration of negative ions can effectively improve the efficiency of oxygen absorption and carbon dioxide emission, increase the nutrition of human brain cells, and maintain a good mental state.The increase of relative humidity in the workshop can also reduce the loss of tobacco leaf breakage and greatly improve economic benefits.
