AI Technical Summary
In existing hydrogen peroxide sterilization equipment, the direct heating and evaporation method causes water and hydrogen peroxide to evaporate together, affecting the purity of the steam, making it difficult to control the temperature accurately, and the heating process may cause hydrogen peroxide to decompose or evaporate incompletely, reducing sterilization efficiency.
The system employs a secondary heating and secondary evaporation method. After initial heating and evaporation in the heating chamber, water and hydrogen peroxide are separated using a condenser. The condenser rod performs condensation, and the high-temperature evaporator performs secondary heating, allowing the hydrogen peroxide to diffuse rapidly into the sterilization chamber. Combined with negative pressure control and temperature/pressure monitoring, purification and efficient evaporation are achieved.
It significantly improves the vaporization efficiency and sterilization effect of hydrogen peroxide, ensures steam purity, avoids the risk of decomposition caused by improper temperature, and improves sterilization efficiency.
