AI Technical Summary

Technical Problem

Existing vertical pressure steam sterilizers release trace amounts of harmful substances into the exhaust gas, which are not properly treated, affecting equipment lifespan and air quality. Furthermore, poorly fixed filters result in ineffective particulate matter absorption.

Method used

A gas treatment structure was designed, which includes an S-shaped flow channel, filter component one, and filter component two. The S-shaped flow channel increases the contact time and path between the gas and water, and the inertial sedimentation and Bernoulli effect are used to accelerate the sedimentation of impurities. The liquid level adjustment component enables the automatic positioning and rapid replacement of the filter screen.

Benefits of technology

It effectively increases the absorption of particulate matter in the gas, ensures stable equipment operation, reduces the emission of harmful substances, improves air quality, and simplifies the replacement and maintenance process of the filter.

Abstract

This utility model discloses a vertical pressure steam sterilizer, including a body and a filter box located on one side of the body. The filter box contains clean water, and a filter assembly is connected to the body. The filter assembly includes an S-shaped flow channel fixed inside the filter box. Addressing the problems of short gas-water surface contact time and insufficient particulate matter absorption in existing technologies, this novel vertical pressure steam sterilizer features a unique S-shaped flow channel structure. After sterilization, the steam discharged from the body enters the S-shaped flow channel inside the filter box through the inlet pipe. The steam meanders within the S-shaped flow channel, significantly increasing the contact path and time between the gas and the water surface. Simultaneously, the double-sloped blocks fixed to the top and side walls of the S-shaped flow channel allow larger particulate impurities in the steam more time to contact the water due to inertia and gradually settle into the water, thus increasing the absorption of particulate matter.
