Nowadays, there are more and more new humidifiers. It is no longer a rigid, monotonous "box-shaped" or "drum-shaped" Humidifier that dominated the world a few years ago. Various new models, plus a variety of brands, like The cartoon bear shape, the "small doctor" shape, the duckbill shape of the small mouth, the letter shape, the electric iron shape and so on are dazzling and dazzling. Drying not only causes harmful static electricity in electronics and printing shops, but also is the enemy of human health. It causes a lot of water loss in the human body, causing tight skin, dry mouth, cleft lip, and getting angry. It can also cause respiratory diseases such as flu and pharyngitis. Indoor air drying can also cause damage to furniture, floors, home appliances, etc., and shorten the service life. Even in the south, in the rainy weather or after using the air conditioner, the indoor air humidity in autumn and winter is only 40% RH or less, which is obviously lower than the normal humidity of the room by 40%~70% RH, and a humidifier is added to enjoy the warm and humid Autumn and winter.
The working principle and usage of various types of humidifiers can be summarized as follows:
Household humidifiers and industrial humidifiers are commonly used in three types, namely ultrasonic humidifiers, electric heating humidifiers, wet film evaporative humidifiers, and pure humidifiers.
Ultrasonic humidifier has been on the market for many years. It uses the principle of ultrasonic high-frequency oscillation to atomize water into ultra-fine particles of 1~5μm. The water mist is diffused into the air through the air moving device to achieve uniform humidification air. The ultrasonic humidifier has high humidification intensity, uniform humidification, high humidification efficiency, and has the advantages of power saving and long service life, and has been very popular. However, the shortcomings of the ultrasonic humidifier are also obvious, that is, there are certain requirements for water quality. The new generation of ultrasonic humidifiers uses humidity control to automatically adjust the amount of humidification with humidity changes. The dynamic balance principle is used to control the relative humidity of the environment between 45% and 65% RH. When the indoor relative humidity is higher than the set upper limit H, the humidifier will automatically stop humidification, so that the environment is always in a constant humidity state, and the workshop can also cool down and humidify. In addition to daily humidified air, this humidifier can also be used as a cosmetic bath.
The electric heating type humidifier is a simple humidification method of the technology, and the heating element is used to heat the water to the boiling point, and the water vapor is released into the air. There is no requirement for water quality, but the disadvantage is that the energy consumption is large, the dry burning is not possible, the safety factor is low, and the heater is prone to scale.
The pure humidifier is a new technology just adopted in the humidification field. It removes calcium and magnesium ions from the water through molecular sieve evaporation technology and completely solves the "" problem caused by poor water quality. The air is washed by the water curtain, the air is humidified, the air is purified, and the humid air is sent to the room through the air moving device, thereby improving the environmental humidity. The humidifier can also filter the air and kill the bacteria, not only make the humidification more pure, but also wash the air with clean water, effectively eliminate the pollution in the air, promote the indoor air circulation, ensure the human health to a greater extent, and lower the respiratory tract. The probability of infection.
The high-pressure spray humidifier is used to install the filter, pump unit, water tank and control box of the humidifier in the workshop or machine room, and the spray system (nozzle, pipe) and the like are installed in the top of the workshop. The humidification method is that the tap water is pressurized by the humidifier main body and filtered by ultrafine filtration, and is sprayed at a high speed by a special nozzle atomization to form a water mist particle of 5 to 10 μm, which is exchanged with the flowing air to absorb air. The heat in the body, vaporization and evaporation, increase the humidity of the air, achieve the humidification treatment of the air, and at the same time play the role of cooling the dust.
The working principle of the wet film evaporating humidifier for the central air conditioner is very simple. The water flows uniformly from the top of the wet film through the steam trap along the corrugated surface of the wet film, so that the wet film is evenly wetted from top to bottom, when the heat is dry. When air flows through the surface of the wet film, it exchanges heat with the moisture in the wet film. The water is evaporated by heat and turns into water vapor, which increases the humidity of the air, so that the dry hot air becomes clean and humid air.
Wet film material (also known as "Sideke") is the core of the wet film humidifier. It is based on plant fiber and treated with special component resin to form a corrugated plate-like overlapping polymer compound. The water absorption and shortcomings are poor self-cleaning ability and easy mold growth.
