Structure Diagram
Working Principle
1. Principle
(1) Water exists in three forms: solid, liquid, and vapor. In the humidification industry, it is trying to use external energy to convert liquid water into vapor water, and then send it to the space that needs to be humidified by external force.
(2) Water does not conduct electricity when it exists in pure water form. The reason why tap water in daily use can conduct electricity is because there are a lot of mineral salts in the water. The working principle of the electrode steam humidifier is to use the conductivity of water.
(3) When the water with mineral salts enters the humidification barrel through the water inlet valve, the electrode sheet on the upper part of the humidification barrel will be immersed in the water as the water level gradually rises. Since the water with mineral salts is a conductor, when the water and the electrodes The contact of the plates will form a path. At this time, we apply a voltage to the electrode plates, and the ions in the water will move at high speed to generate heat energy, so that the water will heat up and generate clean saturated steam, which will then be sent to the air conditioning box or air duct through the steam diffusion device. , so as to achieve the purpose of humidifying the air.
(4) According to the Joule effect, the steam production is proportional to the current, and then proportional to the water level. This current is measured by the current transformer, and the water level is adjusted through the cycle of the water inlet valve and the drain valve. Current and steam production are precisely adjusted.
(5) The water level will drop when evaporating, but the steam cannot take away the mineral salts in the water, so the concentration of mineral salts in the water will increase, so the conductivity will also increase. Once the current reaches the upper limit set by the microprocessor control, The drain valve will discharge high-concentration water, and then replenish new water through the water inlet valve to achieve the purpose of dilution, thereby protecting the humidification barrel. The scale generated by long-term operation will adhere to the electrode plate, which will block the contact between the electrode plate and the ions in the water, thus affecting the humidification capacity, so the humidification barrel should be cleaned and replaced regularly.

Product Features
(1) Precisely controlled by microcomputer, and standard liquid crystal display operator is convenient for operation setting and display.
(2) It can accept controller signal and sensor signal; it can accept switch signal and proportional signal.
(3) The remote monitoring function is optional, and three sets of dry contacts are provided as remote warning functions such as start-stop, humidifier maintenance and fault diagnosis.
(4) It has a fault diagnosis function, and the standardized fault diagnosis program continuously monitors the operating conditions and displays them in codes. In this way, the user can reduce the cost and expense of fault repair and cleaning.
(5) Real-time steam output, operating current, control signal, demand percentage feedback, automatic timing maintenance warning, and humidification cylinder replacement warning.
(6) Variable output control, which can be adjusted down to 20% output.
(7) Good expandability, seven groups can be connected in parallel.
(8) High liquid level alarm and anti-overflow design.
(9) The material of the humidifying barrel is made of special engineering plastics, which is resistant to high temperature and aging, flame-retardant and scale-resistant (optional), and the automatic drainage and cleaning function designed by the system prolongs the service life of the humidifying barrel.
(10) Considering the convenience of installation and maintenance, the front and sides of the body are designed to be disassembled, allowing direct inspection of the core structure and circuits of the body.
Scope of Application
Application industries: hospitals, pharmaceutical factories, circuit boards, liquid crystals, optoelectronics, semiconductors, offshore platforms, ships, nuclear power, aerospace, military and other fields. .
Considerations for choosing an electrode steam humidifier
(1) Isothermal humidification, rapid response and easy control, so it can be precisely controlled.
(2) Complete sterilization, no dirt, no white powder, so hospitals use electrode humidification.
(3) Small size, easy to install on site and save space.
(4) The humidification output is large, the absorption efficiency is high, and a relatively high relative humidity can be achieved.
(5) Since the electrode type steam humidifier uses ions in the water to conduct electricity, there is no current when there is no water, and there is no possibility of dry burning, so it is extremely safe. The reason why all use electrode steam humidifiers.
(6) The use of water quality does not require pure water after water treatment, municipal tap water is sufficient, which saves the cost of water treatment.
