specific Embodiment approach 1

[0018] Specific embodiment one: what this embodiment records is a kind of automatic control air-conditioning pipeline ultraviolet ray disinfecting method, described method steps are as follows:

[0019] Step 1: Online collection of indoor viruses, judging the type and concentration of the virus, judging the places where the pollutants are not easy to discharge through the airflow organization, and considering the areas where the virus is more likely to spread in the room, so as to arrange the aerosol sampling points reasonably;

[0020] Epidemiology shows that the transmission of most microorganisms indoors is caused by droplet transmission or the spread of microbial aerosols. Respiratory diseases such as coronavirus, influenza virus, respiratory syncytial virus, human adenovirus, rhinovirus, etc. When an infected person sneezes, coughs and talks, the pathogenic bacteria attach to the large number of tiny droplets produced by the droplets, and the likelihood of transmission dep...

specific Embodiment approach 2

[0023] Embodiment 2: An automatically controlled ultraviolet ray disinfecting method for air-conditioning ducts described in Embodiment 1, the first step is specifically: the virus detection equipment adopts the Raman virus identification principle, and adopts vertically arranged filter pores with differences High-efficiency carbon nanotube forests are used as samplers to capture different viruses, and in-situ Raman spectroscopy analysis is performed on the captured viruses. Bio-intelligent chips are configured in the detection equipment to maintain virus viability and purify it for use in the respiratory tract Rapid enrichment and optical identification of viruses; through the principle of multi-virus capture components combined with surface-enhanced Raman spectroscopy, real-time enrichment and identification of different emerging strains (or unknown viruses), and time-consuming, virus capture and detection Takes only minutes and enriches 70-fold; as low as 10 2 EID 50 Detectio...

specific Embodiment approach 3

[0024] Embodiment 3: In Embodiment 1, an automatically controlled ultraviolet ray disinfecting method for air-conditioning pipelines, the carbon nanotube forest is an elongated carbon nanotube array prepared by a water-assisted chemical vapor deposition method. Tube diameter is 0.25 ~ 25nm, about 1 cm long. It has a hydrophilic layer on the top surface and a super-hydrophobic layer on the bottom, so that water molecules are trapped inside the nanotubes.

[0025] The present invention proposes a portable microfluidic platform including carbon nanotube arrays with differential filtering porosity for rapid enrichment and optical identification of viruses. Different emerging strains (or unknown viruses) can be enriched and identified in real-time by combining surface-enhanced Raman spectroscopy with multivirus capture components. More importantly, after virus capture and detection on the chip, the virus remains viable and purified from the microdevice, allowing subsequent in-depth...

Abstract

The invention discloses an automatically-controlled air conditioner pipeline ultraviolet disinfection and sterilization method and system, and belongs to the technical field of central air conditionerpipeline ultraviolet disinfection and sterilization. Aiming at the problems of the non-ideal disinfection effect and the low disinfection speed of an existing disinfection device, the method comprises the steps that indoor viruses are collected on line, the types and concentrations of the viruses are judged, places where pollutants are not easy to discharge are judged through air distribution, and aerosol sampling points are arranged at the places; time and attenuation constants are introduced into a formula according to the virus types through a program, and irradiation intensity is calculated; the irradiation intensity of each point of a pipeline is calculated by using a computer through the formula, comparing is conducted to obtain a minimum value, the minimum value is compared with the obtained irradiation intensity, and the on-off state of an ultraviolet lamp is adjusted so as to kill the viruses. Computer program control is adopted, the intensity of the ultraviolet lamp meetingthe maximum bacterium killing concentration is worked out, automatic recognition and conversion are achieved through a multi-line time control switch, the sterilization effect is guaranteed, and meanwhile the energy can be saved to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet disinfection of central air-conditioning pipelines, and in particular relates to an automatically controlled ultraviolet disinfection method and system for air-conditioning pipelines. Background technique [0002] At present, the existing disinfection technologies mainly include the following types: 1. Circulating wind type ultraviolet disinfection machine, which can meet the requirements of disinfection of indoor air environment when there are people or pets in the room, and has good light shielding and high radiation intensity, but Its disinfection speed is slow and its application area is narrow, so it is not suitable for central air-conditioning system disinfection. 2. The ozone air disinfection machine produces a large amount of ozone and can only be used under unmanned conditions. At the same time, ozone is destructive to various items. However, ozone disinfection has the advantages of ...
