汽化过氧化氢除残设备的研发与设计

Design and Development of Vaporized Hydrogen Peroxide Residue Removal Equipment

过氧化氢灭菌运用广泛,在实际灭菌完成后,处理残留的过氧化氢仍需要花费大量时间。现有除残设备虽然可以利用风机将被灭菌空间的残留物输送到含有催化器的设备进行分解,但依然存在分解效率低、耗时长等问题。设计了一种汽化过氧化氢除残设备,该除残设备能喷射还原剂在灭菌空间内与过氧化氢反应,且其喷口可以调整喷射方向,通过AnsysFluent软件对流场进行仿真,得到在不同空间内汽化过氧化氢的分布。调整喷口喷射角度,可极大地减少除残时间,大大降低灭菌周期。

Hydrogen peroxide sterilization is widely used.After the actual sterilization,it still takes a lot of time to dispose of the residual hydrogen peroxide.Although the existing decontamination equipment can use a fan to transport the residues in the sterilized space to the equipment containing the catalyst for decomposition,there are still some problems such as low decomposition efficiency and long time-consuming.A vaporized hydrogen peroxide residue removal equipment was designed,which could spray reducing agent to react with hydrogen peroxide in the sterilization space,and its nozzle could adjust the spray direction.The distribution of vaporized hydrogen peroxide in different spaces was obtained by simulating the flow field with AnsysFluent software.The adjustment of the spray angle of the nozzle could greatly reduce both the residue removal time and the sterilization cycle.
