Vertical pressure steam sterilizer with safe exhaust function

Abstract

The invention discloses a vertical pressure steam sterilizer with a safe exhaust function, and relates to the technical field of pressure steam sterilizers, in particular to a vertical pressure steamsterilization device with a steam self-generation function and a safe exhaust function. A steam generator is arranged at the bottom in a sterilization cavity; a lower output port of the sterilizationcavity is respectively communicated with an electromagnetic valve A and an electromagnetic valve B through a pipeline and a tee joint A; the electromagnetic valve A and the electromagnetic valve B areconnected with the input end of the filtering cavity through a pipeline and a tee joint B; a filter element is arranged in the filter cavity; the filter element is a PP shell filter element; the output end of the filtering cavity is sequentially connected with an electromagnetic valve C, a condenser B and a cooling box through pipelines; the cooling box is connected with the rear cooling barrel through a pipeline; a condenser A is arranged on a pipeline between the electromagnetic valve A and the tee joint B; a water outlet is formed in the bottom of the sterilization cavity. According to thetechnical scheme, the problems that in the prior art, the equipment maintenance cost is increased, and liquid sterilization cannot be conducted are solved; and the problem that a gas filtering deviceis not provided, so that a gas safe discharging function cannot be realized can be solved.

Description

technical field [0001] The invention relates to a vertical pressure steam sterilizer with safe exhaust, and relates to the technical field of pressure steam sterilizers, in particular to a vertical pressure steam sterilizer with a self-generating safe exhaust function of steam. Background technique [0002] The exhaust safety standard requirements of the sterilizer are as follows: [0003] 1. The sterilizer should be equipped with an external exhaust treatment device, and the external exhaust should be sterile. [0004] 2. If the exhaust gas is sterilized with a high-efficiency filter, the filter should meet the following requirements: [0005] 2.1. The filtering effect of filtering particles with a diameter of 0.2 μm is not more than 99.99%; [0006] 2.2. Made of corrosion-resistant and biodegradable materials, the structure of the filter should protect the filter material to the greatest extent; [0007] 2.3. It can withstand high temperature steam not lower than 140℃, ...

AI Technical Summary

Problems solved by technology

[0005] 2.1. The filtering effect of filtering particles with a diameter of 0.2 μm is not more than 99.99%;

[0015] The existing bottom-exhaust steam self-generating vertical pressure steam sterilizer includes: steam generator, sterilization chamber, solenoid valve A, condenser, and cooling box. Because there is no gas filtering device in the structure, safe gas discharge cannot be realized. Function
