Embodiment 1

[0028] Adopt the method for disinfection, sterilization and deodorization of the present invention to process the exhaust gas of the central suction system of a certain hospital, the steps are as follows:

[0029] (1) Impurity removal: Use a centrifugal fan to pass the exhaust gas of the hospital center suction system into the impurity removal section. In the impurity removal stage, a static pressure space and a filter layer with a thickness of 100mm are set. The wind speed of the controlled gas is 0.3m / s, and the residence time is 1s, the gas-liquid separation is carried out by means of gravity sedimentation and physical interception, and the impurities and liquid droplets removed by the gas-liquid separation are diverted and discharged to the hospital water treatment device for treatment, and the gas enters the plasma sterilization and disinfection treatment stage;

[0030] (2) Plasma sterilization and disinfection: the discharge form of double dielectric barrier discharge is...

Embodiment 2

[0034] Adopt the method for disinfection, sterilization and deodorization of the present invention to process the exhaust gas of the central suction system of a certain hospital, the steps are as follows:

In the impurity removal stage, set up a static pressure space and a 120mm thick filter layer, control the wind speed of the gas to 0.4m / s, and the residence time to be 0.5s, the gas-liquid separation is carried out by means of gravity sedimentation and physical interception, and the impurities and liquid droplets removed by the gas-liquid separation are diverted and discharged to the hospital water treatment device for treatment, and the gas enters the plasma sterilization and disinfection treatment stage;

[0036] (2) Plasma sterilization and disinfection: the discharge form of double dielectric barrier discharge is adopt...

Embodiment 3

[0040] Adopt the method for disinfection, sterilization and deodorization of the present invention to process the exhaust gas of the central suction system of a certain hospital, the steps are as follows:

[0041](1) Impurity removal: Use a centrifugal fan to pass the exhaust gas from the hospital’s central suction system into the impurity removal section. In the impurity removal stage, set up a static pressure space and a 150mm thick filter layer, control the wind speed of the gas to 0.5m / s, and the residence time to be 0.3s, the gas-liquid separation is carried out by means of gravity sedimentation and physical interception, the impurities and liquid droplets removed by gas-liquid separation are diverted and discharged to the hospital water treatment device for treatment, and the gas enters the plasma sterilization and disinfection treatment stage;

[0042] (2) Plasma sterilization and disinfection: the discharge form of double dielectric barrier discharge is adopted, the dia...

Abstract

The invention relates to the technical field of medical sterilization, and particularly relates to a treatment method for online real-time disinfection, sterilization and deodorization of exhaust gas of a hospital center suction system. The treatment method for online real-time disinfection, sterilization and deodorization of the exhaust gas of the hospital center suction system comprises the following steps that gas-liquid separation is carried out on the exhaust gas of the hospital center suction system in a gravity settling and physical intercepting mode; a double-dielectric barrier discharge mode is adopted, and plasma is used for carrying out online real-time sterilization, disinfection and deodorization on the gas subjected to impurity removal; and inactivated thalli in the gas subjected to plasma sterilization and disinfection are filtered through an efficient filtering material, and then the treatment of the exhaust gas of the hospital center suction system is completed. According to the treatment method for online real-time disinfection, sterilization and deodorization of the exhaust gas of the hospital center suction system, bacteria or viruses in the exhaust gas can be killed online in real time, the sterilization efficiency is high, and meanwhile the problem of peculiar smell of the exhaust gas is solved.

Description

technical field [0001] The invention relates to the technical field of medical sterilization, in particular to a treatment method for online real-time disinfection, sterilization and deodorization of exhaust gas from a suction system in a hospital center. Background technique [0002] The emergence and spread of the new crown epidemic have made people pay more attention to preventing cross-infection, especially the spread of viruses or bacteria that use air as the medium. The hospital central suction system is mainly composed of central suction station, suction pipeline, negative pressure suction terminal and so on. The negative pressure source is the suction of the vacuum pump unit in the central suction station. The suction system pipeline reaches the suction negative pressure value, and suction is generated at the terminal of the operating room, rescue room and each ward for medical use. When the vacuum pump is working, it will exhaust air into the environment. The exhau...
