Technical Field

Background

The ethylene oxide sterilizer is equipment for performing low-temperature fumigation sterilization on articles sealed in a sterilization chamber by using ethylene oxide gas with certain concentration under the conditions of certain temperature, pressure and humidity, is important equipment used in the sterilization process of medical equipment production, and is widely applied to the medical equipment production.

Ethylene oxide vaporizers are an important component of ethylene oxide sterilizers. The sterilizing medium of the ethylene oxide sterilizer, ethylene oxide, is a high-efficiency low-temperature sterilizing agent. Ethylene oxide is a highly toxic, flammable and explosive chemical substance, is a colorless transparent liquid at low temperature, has a vaporization temperature of 10.7 ℃, is slightly heavier than air after vaporization, and is easily polymerized when heated. Commercial ethylene oxide is supplied as a bottled, sealed liquid. The ethylene oxide sterilizer is used for sterilizing the packaged medical instruments by requiring the input ethylene oxide to be in a complete vaporized state so that the ethylene oxide can penetrate through the package. The liquid bottle has certain pressure, and quantitative completely vaporized ethylene oxide gas is introduced into the sealed sterilization chamber in a negative pressure state through a pipeline for sterilization. Since the ethylene oxide is in liquid state in the bottle and must be changed into gas when reaching the sterilization chamber, the short distance from the bottle to the sterilization chamber cannot be completely vaporized, and the ethylene oxide is in gas-liquid mixed state. Therefore, a vaporizer is required to be added between the liquid bottle and the sterilization chamber to meet the requirement of complete vaporization of the ethylene oxide.

Because ethylene oxide is easy to polymerize in a vaporized state, the polymer has higher hardness and is firmly combined with the pipe wall, the cleaning is difficult, the polymer is accumulated too much and can block the gas pipe, the conveying of the ethylene oxide is influenced, and the vent pipe is in a disc shape, the mechanical cleaning cannot be carried out, the pipeline is blocked too much, and the vaporizer is scrapped. The main problem with coiled tube vaporizers is the difficulty in cleaning the ethylene oxide polymer and early rejection.
