Dry steam humidifier

1、 Overview and Explanation Saturated steam enters from the steam inlet and flows axially in the steam sleeve rod. The latent heat of steam is used to preheat the central spray rod, ensuring that the steam sprayed from the central spray rod is pure dry steam, that is, steam without condensed water. After saturated steam enters the casing, it enters the steam water separation chamber. A baffle is installed inside the separation chamber to allow steam to rotate and flow vertically upward after entering the separation chamber, thereby efficiently separating 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 dry steam enters the central spray bar and is sprayed out from the spray hole with a soundproofing device to achieve humidification of the air. As shown in the figure below: Determine the left-right type of dry steam humidifier based on the form or installation requirements of the air conditioning unit. Generally, air conditioning units are right-hand type and should be equipped with right-hand type dry steam humidifiers; On the contrary, a left type dry steam humidifier should be installed. Only in this way can we ensure that the sprayed dry steam flows in the opposite direction of air flow. The left and right judgment rules for dry steam humidifiers: When viewed from the direction of the spray rod towards the evaporator, if the steam sprayed from the spray rod is to the left, then the dry steam humidifier is a left type; On the contrary, the dry steam humidifier is of the right-hand type.

IICharacteristics of dry steam humidifier 1. Adopting advanced foreign technology and structure for steam water separation, it achieves thorough separation without any water spraying phenomenon. 2. It belongs to isothermal humidification with high humidification efficiency, reaching over 96%. 3. The unique double-layer steam sleeve ensures that the sprayed steam does not carry any condensed water. 4. Made of all stainless steel construction, it is beautiful and durable. 、 5. Unique noise reduction structure ensures that there are no whistling or noise during the flow and spraying of steam. 6. The integration of electric or electromagnetic dry steam enables remote and precise adjustment and control of humidity. When the humidification capacity is relatively large or the cross-sectional size of the air conditioning unit is large, a multi spray bar structure or multiple parallel units should be used. 8. The left and right types of dry steam humidifiers can be interchanged.

5Electric dry steam humidifier（SMDSeries)

The actuator of the electric dry steam humidifier uses steam electric regulating valves and electric actuators, which comply with international IEC standards. It can receive control signals provided by control instruments and convert them into corresponding linear displacements, thereby automatically adjusting steam flow and achieving remote and precise humidity control.

Performance parameters of electric actuators

The actuator of the electric basic type dry steam humidifier adopts a steam regulating valve and a basic type actuator (VA7150). Connect AC+24V, the actuator motor rotates forward, and the regulating valve opens; Connect to AC 24V, reverse the actuator motor, and close the regulating valve. The opening and closing of the regulating valve is achieved through the forward/reverse rotation of the motor, completing the adjustment and control of the humidification amount.

The actuator of the electronic positioning type dry steam humidifier adopts a steam regulating valve and an electronic positioning type calculator. The actuator can accept analog electrical signals of DC 0-10V, linearly adjust the valve opening degree, achieve linear proportional adjustment of steam output, and achieve precise control of the humidifier. This system is suitable for humidification applications with high requirements for processability or control accuracy.

Our company can select steam electric control valves and electric actuators from companies such as Siemens and Honeywell according to customer requirements.

Our company can produce electric dry steam humidifiers that must automatically stop humidifying during sudden power outages according to customer requirements.

The first type is an electric dry steam humidifier that combines a steam electric regulating valve and a steam solenoid valve.

Second option: Install an electric actuator with spring reset function (such as Siemens SKD32.50)
The third method: using standard configuration (Johnson electric actuator)+external power-off reset device.
