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

The utility model discloses a vertical pressure steam sterilizer which comprises a sterilizer body and a filter box located on one side of the sterilizer body, clear water is contained in the filter box, the filter box and the sterilizer body are connected with a first filter assembly, and the first filter assembly comprises an S-shaped flow channel fixed in the filter box. According to the novel vertical pressure steam sterilizer, a unique S-shaped flow channel structure is designed through the filter assembly I aiming at the problems of short contact time of gas and water surface and insufficient particulate matter absorption amount in the prior art, after the sterilization operation is completed, steam discharged by the sterilizer body enters the S-shaped flow channel in the filter box through the air inlet pipe, and the steam flows in the S-shaped flow channel in a winding manner; the contact path and time of gas and the water surface are greatly increased, meanwhile, the double-inclined-plane blocks fixed to the top end and the side wall in the S-shaped flow channel enable large-particle impurities in steam to have more sufficient time to make contact with water due to the inertia effect and gradually settle into the water, and the absorption amount of particles is increased.
