The residual gas treatment system in ethylene oxide sterilization equipment is designed to solve the problem of ethylene oxide gas accumulation during the sterilization process and ensure that the gas concentration inside the equipment is always kept within a safe range. This system uses a series of precisely designed processes and technical means to effectively collect, treat and discharge the waste gas generated during the sterilization process, thereby ensuring environmental safety, personnel health and stable operation of the equipment.

Waste gas collection and treatment: During the sterilization process, ethylene oxide gas reacts with microorganisms in the articles to produce waste gas containing ethylene oxide and its reaction products. The residual gas treatment system first collects these waste gases quickly through the built-in exhaust device to prevent them from leaking. Subsequently, the waste gas will undergo pretreatment steps such as dust removal and water removal to remove large particles and moisture, providing a clean waste gas source for subsequent treatment.
Catalytic conversion and harmless treatment: The pretreated waste gas will enter the catalytic conversion unit, which is the core part of the residual gas treatment system. Under the action of the catalyst, ethylene oxide gas reacts with water to produce harmless substances such as ethylene glycol. This process not only reduces the toxicity of the exhaust gas, but also reduces its potential threat to the environment. At the same time, the catalytic conversion unit can effectively remove other harmful substances in the exhaust gas, such as acidic gases, volatile organic compounds, etc., to ensure that the exhaust gas meets environmental standards.
Exhaust gas treatment and emission: After catalytic conversion, the exhaust gas still needs to be further treated to ensure that it is completely harmless. This usually includes removing residual trace harmful substances through adsorption, washing, etc. Finally, the treated exhaust gas will be tested to ensure that it meets the emission standards before it is discharged into the atmosphere through the chimney at high altitude. This process not only ensures environmental safety, but also avoids complaints and fines caused by improper exhaust gas emissions.

An effective residual gas treatment system is not only related to environmental safety and personnel health, but also the key to reducing the risk of equipment failure and explosion. Ethylene oxide gas accumulates inside the equipment, which may cause an explosion due to excessive concentration or changes in temperature, pressure and other conditions. The existence of the residual gas treatment system ensures that the concentration of ethylene oxide gas inside the equipment is always within the safe range by continuously and efficiently removing the waste gas, thereby greatly reducing the risk of explosion.

Prevent gas accumulation: The residual gas treatment system can monitor the gas concentration inside the equipment in real time. Once it detects that the ethylene oxide gas concentration exceeds the safety threshold, it immediately starts the treatment process and quickly discharges the waste gas. This process effectively prevents the accumulation of gas inside the equipment and reduces the risk of explosion.
Protect equipment components: Ethylene oxide gas and its reaction products are corrosive. If they are discharged directly without treatment, they may accelerate the corrosion and aging of equipment components, resulting in frequent equipment failures. An effective residual gas treatment system can remove corrosive substances in the waste gas, protect equipment components from damage, and extend the service life of the equipment.
Improve equipment stability: The stable operation of the residual gas treatment system helps maintain the overall performance of the sterilization equipment. By continuously and efficiently removing the waste gas, the system can ensure that the gas environment inside the equipment is always in the best state, thereby improving the stability of the equipment and the sterilization efficiency.

In order to ensure that the residual gas treatment system in the ethylene oxide sterilization equipment can operate continuously and effectively, regular maintenance and care are essential. This includes checking the working status of key components such as exhaust devices, catalysts, and exhaust treatment devices, replacing aging components and consumables in a timely manner, and regularly cleaning and disinfecting the system.

Regular inspection and maintenance: Operators should regularly inspect the residual gas treatment system, including checking whether the exhaust device is unobstructed, whether the catalyst is ineffective, and whether the exhaust treatment device is blocked. Once an abnormality is found, measures should be taken immediately to repair or replace it.
Replacement of consumables and parts: Consumables such as catalysts and adsorbents in the residual gas treatment system will gradually fail over time. Therefore, operators should regularly replace these consumables to ensure that the system's treatment effect is always maintained in the best condition.
Cleaning and disinfection: In order to prevent bacteria, viruses and other microorganisms from breeding in the residual gas treatment system, operators should regularly clean and disinfect the system. This not only maintains the hygiene of the system, but also extends its service life.

In addition to regular maintenance and care, professional training for operators is also the key to ensuring the continued effective operation of the residual gas treatment system. Through training, operators can understand the operating procedures, maintenance methods, and emergency treatment measures of the equipment, and improve safety awareness and emergency response capabilities.

Operation process training: Operators should be familiar with the operation process of the residual gas treatment system, including starting, stopping, troubleshooting, etc. Through training, they can master these skills to ensure that the system can be quickly started and operate normally when needed.
Maintenance training: Operators should understand the maintenance methods of the residual gas treatment system, including inspection, replacement of consumables, cleaning and disinfection, etc. Through training, they can master these skills to ensure that the system is always in the best condition.
Emergency response training: In an emergency, operators should be able to respond quickly and correctly to ensure the safety of personnel and equipment. Therefore, they should receive emergency response training and understand the response measures and escape routes for various emergencies.
