The humidification system of the ethylene oxide sterilization workshop is mainly composed of steam generators, steam pipes, nozzles and control devices. These parts work together to achieve precise control of humidity.
Steam generator: As the "heart" of the humidification system, the steam generator is responsible for generating high-temperature steam. It usually uses a heating element to heat water to evaporate it into steam. The selection of the steam generator should be based on the scale of the sterilization workshop, humidification capacity and steam pressure requirements to ensure a stable supply of steam and a suitable temperature.
Steam pipe: The steam pipe is a bridge connecting the steam generator and the nozzle. It transports high-temperature steam from the generator to the nozzle to ensure that the temperature and pressure of the steam are stable during the transportation process. The steam pipe should be made of high-temperature resistant and corrosion-resistant materials to reduce the risk of heat loss and steam leakage.
Nozzle: The nozzle is the "exit" of the humidification system and is responsible for evenly spraying steam into the sterilization room. The selection of the nozzle should be based on the spatial layout, humidification capacity and steam pressure requirements in the sterilization room. By properly arranging the position and number of nozzles, the uniform distribution of steam in the sterilization chamber can be ensured, thereby achieving precise control of humidity.
Control device: The control device is the "brain" of the humidification system, responsible for monitoring and adjusting the operating parameters of the humidification system. It usually includes humidity sensors, temperature sensors, controllers and actuators. The humidity sensor is used to monitor the humidity level in the sterilization chamber in real time, and the temperature sensor is used to monitor the temperature of the steam. The controller adjusts the steam supply in real time through the actuator according to the data fed back by the sensor to keep the humidity within the optimal range.

During the ethylene oxide sterilization process, the humidification system achieves stable control of the humidity in the sterilization chamber by accurately controlling the steam supply. This process mainly includes the following steps:
Humidity monitoring: The humidity sensor in the control device monitors the humidity level in the sterilization chamber in real time. The sensor usually adopts a capacitive or resistive principle to reflect the humidity level by measuring the water molecule content in the air. The sensor feeds back the monitored data to the controller to provide a basis for subsequent adjustments.
Steam supply regulation: The controller adjusts the output of the steam generator in real time through the actuator according to the data fed back by the humidity sensor. When the humidity is lower than the set value, the controller will increase the output of the steam generator and increase the supply of steam; when the humidity is higher than the set value, the controller will reduce the output of the steam generator and reduce the supply of steam. Through this adjustment process, it can be ensured that the humidity in the sterilization room is always kept within the optimal range.
Uniform distribution of humidity: In order to ensure the uniform distribution of humidity in the sterilization room, the humidification system usually uses multiple nozzles for spraying. The position and number of nozzles should be reasonably arranged according to the spatial layout in the sterilization room. By arranging the nozzles reasonably, it can be ensured that the steam is evenly distributed in the sterilization room, thereby avoiding the problem of excessive or low local humidity.
Humidity range setting: In the ethylene oxide sterilization process, the optimal range of humidity is usually 60%~80%RH. This humidity level can effectively prevent the hydrolysis of ethylene oxide and ensure the smooth progress of the sterilization process. Therefore, in the design and operation of the humidification system, the humidity range should be reasonably set according to the actual situation to ensure the sterilization effect and equipment safety.

The humidification system plays a vital role in the ethylene oxide sterilization workshop. It not only optimizes the sterilization effect by precisely controlling the humidity level, but also protects the normal operation of the sterilization equipment and extends its service life.
Optimize sterilization effect: The appropriate humidity level can improve the penetration and alkylation of ethylene oxide, thereby improving the sterilization efficiency and quality. The humidification system ensures the stability and uniformity of the humidity in the sterilization chamber by precisely controlling the humidity, thereby improving the sterilization effect.
Prevent ethylene oxide hydrolysis: Too low humidity may cause ethylene oxide to undergo hydrolysis reaction and generate by-products such as ethylene glycol. These by-products will not only reduce the sterilization efficiency, but may also cause corrosion to the sterilization equipment. The humidification system effectively prevents the hydrolysis of ethylene oxide and protects the normal operation of the sterilization equipment by maintaining an appropriate humidity level.
Extend the service life of the equipment: The appropriate humidity environment can reduce corrosion and oxidation reactions inside the equipment and reduce the equipment failure rate. The humidification system provides a good operating environment for the sterilization equipment by precisely controlling the humidity, thereby extending its service life.
Improve production efficiency: The humidification system optimizes the sterilization process parameters and shortens the sterilization time by precisely controlling the humidity. This not only improves production efficiency, but also reduces sterilization costs.

In order to ensure the long-term stable operation of the humidification system and the reliability of the sterilization effect, the humidification system needs to be maintained and serviced regularly. This includes the following aspects:
Cleaning the nozzle: Clean the nozzle regularly to prevent the nozzle from clogging or scaling. The clogging of the nozzle will affect the steam injection effect, thereby affecting the uniform distribution of humidity.
Check the steam pipe: Regularly check the joints and seals of the steam pipe to ensure that there is no steam leakage. Steam leakage will lead to insufficient steam supply, thereby affecting the humidity control effect.
Calibrate the sensor: Regularly calibrate the humidity sensor and temperature sensor to ensure the accuracy and reliability of the measurement data. The accuracy of the sensor directly affects the control effect of the humidification system.
Replace wearing parts: Regularly replace wearing parts in the humidification system, such as nozzles, seals, etc. The wear of wearing parts will affect the normal operation and control effect of the humidification system.
