AI Technical Summary
In existing small-scale ethylene oxide sterilizers, the supply and return air are concentrated in a small-diameter pipe, resulting in concentrated airflow in the sterilization chamber, which affects vaporization and diffusion efficiency, creates dead air zones, and leads to uneven sterilization effect.
A wind-wall type internal circulation ethylene oxide sterilization device is designed, which adopts a hollow parallel sidewall and through-hole structure, combined with ventilation pipes and circulating fans to form a uniform gas circulation channel, avoid airflow dead zones, and improve gas diffusion efficiency.
It achieves uniform gas distribution within the sterilization chamber, avoids dead zones in airflow, improves sterilization efficiency, simplifies the device structure, reduces the overall volume, and facilitates installation and maintenance.

A wind wall type internal circulation ethylene oxide sterilization apparatus including a sterilization case, characterized by, The sterilization chamber has a set of parallel side walls that are hollow, and the inner wall surface of the set of parallel side walls is evenly distributed with multiple through holes. The set of parallel side walls are connected by ventilation pipes, and there are circulating fans on the ventilation pipes.
2. A wind wall type internal circulation ethylene oxide sterilization apparatus as claimed in claim 1, wherein The hollow sidewall includes a support plate and a wind plate. The wind plate is bent to form a wind box with one open end, and the bent part of the wind box is continuously closed. The open end of the wind box is connected to the support plate in a sealed manner in a one-to-one correspondence to form a wind gap.
3. A wind wall type internal circulation ethylene oxide sterilization apparatus as claimed in claim 2, wherein The sterilization chamber is rectangular in shape, and a set of parallel sidewalls arranged along the length of the sterilization chamber are hollow.
4. The air-wall type internal circulation ethylene oxide sterilization device as described in claim 2, characterized in that, The air plate is rectangular in shape, with its four sides bent at 90° to form four side edges, which are then welded together.
5. A wind wall type internal circulation ethylene oxide sterilization apparatus as claimed in claim 3, wherein It also includes air ducts, which are arranged along the length of the sterilization chamber; The outer circumferential surface of the duct has a first ventilation opening and a plurality of second ventilation openings. The first ventilation opening is located in the middle of the top of the duct and is connected to one end of the duct. The plurality of second ventilation openings are arranged sequentially along the length of the duct and are connected to the duct.
6. A wind wall type internal circulation ethylene oxide sterilization apparatus as claimed in claim 5, wherein The air duct is installed inside the air chamber, and both ends of the air duct along its length are spaced apart from the inner wall of the corresponding air chamber.
7. A wind wall type internal circulation ethylene oxide sterilization apparatus as claimed in claim 5, wherein The air duct is located at the top of the air chamber. Both ends of the air duct are sealed along its length. The top of the air chamber has a notch that runs along the length of the air duct. The lower part of the air duct passes through the notch and is sealed to the air chamber.
