Medical laboratory air purification system

Abstract

The invention discloses a medical laboratory air purification system which comprises a first air purification unit, a second air purification unit and a controller, wherein the first air purificationunit is used for generating oxygen group high-energy ions, and the oxygen group high-energy ions enter a medical laboratory through a first pipeline and an air outlet; the second air purification unitcomprises ferric oxide and manganese dioxide; the controller is used for controlling the first air purification unit and the second air purification unit, controlling the first air purification unitto work when an infrared detector detects that no person exists in the medical laboratory and the time is in a first preset time period , and keeping the medical laboratory at a first oxygen group high-energy ion concentration; the controller is further used for controlling the first air purification unit and the second air purification unit to stop working when no person exists in the medical laboratory and the time is in a second preset time period later than the first preset time period; and when the infrared detector detects that a person exists in the medical laboratory and the time is ina third preset time period except the first preset time period and the second preset time period, the second air purification unit is controlled to work, and the medical laboratory is kept below a second oxygen group high-energy ion concentration and a first formaldehyde concentration.

Description

technical field [0001] The invention belongs to the technical field of air purification, and more specifically relates to a medical laboratory air purification system. Background technique [0002] In medical institutions or medical research institutions, medical laboratories require large quantities of formaldehyde solutions to store specimens. In the process of specimen processing, xylene is frequently used as a transparent agent. Due to the large amount and frequent use of these reagents, the concentration of formaldehyde and xylene in the specimen collection room, staining and embedding room and other rooms of the pathology department often exceeds the standard. [0003] In order to reduce the concentration of formaldehyde and xylene in the specimen collection room, dyeing and embedding room, etc., the traditional method is to set up a fume hood in the specimen collection room, dyeing and embedding room, etc., and set up a sampling table with exhaust function in the spe...

Problems solved by technology

However, its air outlet is set downwards, which affects the effective and uniform diffusion of positive and negative ion clusters in medical laboratories, and with people's higher requirements for the environment and health, the potential of oxygen group high-energy ions in positive and negative ion clusters on the human body Adverse effects are also receiving greater attention
