Introduction: Dry steam humidifier is a type of humidifier. It is made of stainless steel and uses a mesh steam-water separator to evaporate twice, allowing water and steam to be completely evaporated. perform separation. The efficiency of dry steam humidification is very high. Under normal circumstances, it can reach a humidification rate of more than 95%. It is made of all stainless steel. It not only looks beautiful, but is also very durable during use. It adopts a unique effect structure to ensure that it is sprayed during spraying. There is no noise during the steaming process, and it can also be manually adjusted to realize self-control and adjustment of the ambient humidity, which is convenient and fast. Introduction to dry steam humidifiers
Dry steam humidifiers have a large humidification capacity and emit pure steam. They must have a steam source. It is divided into: manual adjustment control type; solenoid valve control switch type; electric actuator control proportional type. The dry steam humidifier is made of stainless steel and uses a mesh stainless steel steam-water separator to perform secondary evaporation and vaporization to completely separate steam and water.
Working principle of dry steam humidifier
Saturated steam enters the humidifier from the steam inlet. The steam flows axially in the steam sleeve rod. The latent heat of the steam is used to heat the central spray rod to ensure The central spray boom emits pure dry steam, that is, steam without condensed water. After the saturated steam enters the casing, it enters the steam-water separation chamber. The separation chamber is equipped with baffles to cause the steam to rotate and flow vertically upward after entering the separation chamber, thereby efficiently separating the steam and condensed water; the separated condensed water is discharged from the bottom of the separation chamber through a trap. When humidification is required, open the regulating valve and the dry steam enters the central spray rod and is ejected from the nozzle hole with a muffler device to humidify the air.
Characteristics of dry steam humidifier
It has high humidification efficiency, up to 95% or more. It is made of all stainless steel materials, beautiful and durable, and has its unique double-layer steam casing and silencer structure. , to ensure that there is no water spraying when the steam is ejected, and there is no whistle or noise during the flow and injection process of the steam. At the same time, the electric regulating valve, solenoid valve and manual dry steam humidifier can be organically combined to achieve remote and precise adjustment and control of humidity.
1. Introduce foreign advanced water and steam separation technology to make the separation of steam and water more thorough.
2. The external type adopts a unique double-layer casing and silencer device to ensure that the dry steam emitted will never spray water or whistle.
3. Electric and electromagnetic dry steam are integrated structures, which can realize remote and precise control of humidity.
4. The built-in type can help users solve the problem of limited installation space.
5. It belongs to isothermal clean humidification and has high humidification efficiency, which can reach more than 95%.
6. Made of all stainless steel 304 (1Cr18Ni9Ti) material, with beautiful appearance, easy installation, corrosion resistance and long life. 7. The humidification capacity of a single unit can reach up to 760Kg/h, with reliable performance and easy installation.
Classification of dry steam humidifiers
1. Manual adjustment control type;
2. Solenoid valve control switch type
3. Electric Proportional actuator control
Scope of use of dry steam humidifier
Especially suitable for clean and sterile occasions such as hospital operating rooms, wards, electronic workshops, laboratories, pharmaceutical factories, etc. It can also be matched with central air conditioning and used in machinery, electronics, chemical industry, textile, papermaking, printing, instrumentation and other occasions.
Advantages and Disadvantages of Dry Steam Humidifier
It humidifies quickly and evenly, does not contain water droplets, does not consume electricity, and has low operating costs; it must have a steam source and steam pipeline system, and the equipment structure is relatively Complex and high initial investment.
Dry steam humidifier selection guide
1. The control parameters of dry steam humidifier are spray rod diameter and nozzle hole diameter.
2. The humidification amount of the dry steam humidifier is related to the diameter of the spray rod, steam pressure and nozzle hole diameter.
3. The dry steam humidifier has uniform steam distribution and no local excess. Saturation phenomenon; simple installation, low maintenance costs, accurate remote control of humidity; fast and clean humidification, high humidification efficiency, up to 95% or more.
4. Dry steam humidifiers are divided into manual control type, electromagnetic on-off type, electric two-way type and proportional adjustment type according to the control mode.
5. Determine the dry steam humidifier model based on the humidification volume and steam pressure.
Dry steam humidifier installation instructions
1. The humidifier should be installed within the absorption distance, otherwise a multi-nozzle humidifier should be used, and the nozzles should be in line with the direction of the air flow. .
2. The end of the nozzle should be slightly tilted upward so that the condensed water can flow back into the flash chamber. The nozzle should be installed between the heater and the muffler as much as possible to help eliminate steam injection noise.
3. The nozzle should be installed at least 250mm downstream of the surface cooling. Keep a distance of at least 2m between the humidifier nozzle and the control sensing element. When installing multiple nozzles, the nozzle spacing should be equal.
Precautions for using dry steam humidifier
1. Turn on the air conditioner for 3 to 5 minutes before turning on the humidifier, and turn off the humidifier for 5 to 6 minutes before turning off the air conditioner;
2. When starting up the humidifier, the steam source should be turned on first and then the power. When shutting down, the power should be turned off first and then the steam;
3. The pressure of saturated steam is greater than 0.4MPa. The air source should be turned off in time;
4. When the temperature and humidity of the working environment of the humidifier do not meet the technical requirements, it should not be turned on;
5. When maintaining the humidifier, the power supply should be cut off and turned off. Steam source, and drain the condensed water in the humidification tank;
6. When parking for a long time, cut off the power supply, turn off the steam source, and drain the condensed water in the humidification tank;
7. After long-term parking, check whether all parts of the humidifier are reliable before restarting.
Editor’s summary: The above is an introduction to the relevant knowledge about the installation and use precautions of dry steam humidifiers. I hope it can help friends who have needs in this regard!
