A high-temperature negative pressure ventilation disinfection machine and its disinfection method

Abstract

The invention proposes a high-temperature negative pressure ventilation disinfection machine and its disinfection method. The bottom of the waterproof casing of the disinfection machine is provided with an air inlet, and an inlet filter is installed at the air inlet. The valve is divided into two paths, one path is connected to the negative pressure fan through pipeline B, and the other path is connected to the air outlet through pipeline A. There are several heating rods and temperature sensors in pipeline A, and pipeline A bends on the upper part of the waterproof casing. For setting, heat insulating material is arranged on the outside of the zigzag part, and a butterfly valve and an outlet filter screen are arranged in sequence along the air outlet direction at the air outlet. It solves the problem that the virus excreted by the infected person is mixed in the aerosol, which is easy to cause the infection of the personnel in close contact. The invention heats the polluted air through multiple high-temperature zones, and finally the virus is killed in the pipeline, so that the clean air is discharged into the external environment, and a negative pressure fan is used to form a certain negative pressure in the house to complete indoor ventilation and kill viruses Fast, high antivirus efficiency.

Description

technical field [0001] The invention relates to a high-temperature negative pressure ventilation disinfection machine and a disinfection method thereof, belonging to the technical field of disinfection equipment. Background technique [0002] The transmission characteristics of epidemic viruses are highly contagious and highly concealed, and the main transmission route is aerosol transmission. Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gaseous medium. Solid and liquid particles in the atmosphere do Brownian motion, do not settle due to gravity, and can be suspended in the atmosphere for several months. The virus expelled by the infected person through breathing is mixed in the aerosol, which can easily cause infection in close contacts. Contents of the invention [0003] The present invention proposes a high temperature negative pressure ventilation disinfection machine in order to solve the problem mentioned in the...
