The main disinfection and purification machine 6 is used for carrying out final disinfection and purification treatment on the air of the whole system and then sending the air into the inspection room through the air supply outlet 4. The air conditioning system is very easy to generate bacteria, and the air conditioner 15 can adsorb dust and dirt in the air in the operation process, and the dust and the dirt enter the interior of the air conditioner 15, slowly precipitate and breed bacteria. In addition, the air conditioner 15 may generate some condensed water, which reacts with the dirt, and thus legionella may be easily bred. The bacteria in the interior of the air conditioner 15 are legionella, also known as legionella, an opportunistic pathogen that is widely found in nature. At present, the favorite growing environment of the legionella is known to be moist and warm, the temperature which is most suitable for the growth and the propagation of the legionella is 22-25 ℃, and the temperature is just the temperature range regulated by the air conditioner 15, which undoubtedly creates an excellent growing and propagating place for the legionella. The air conditioning system has filter screen, surface cooler and wind pipe for producing bacteria.
The auxiliary disinfection purifier is used for disinfecting and purifying return air and fresh air. The return air is sent to the equipment room 9 by a pipeline in the inspection room, so that a large amount of germs are in the return air; the fresh air is air which is sent in by outdoor air through a pipeline, and dust in the outdoor air is more. Based on the characteristics, the return air and the fresh air are disinfected and purified. The air after the disinfection and purification treatment is sent to an air conditioning system. Therefore, the formation of dust blockage of an air conditioner filter screen and a surface cooler is reduced, the maintenance period is prolonged, and the refrigeration and heating efficiency is improved, so that the system is more energy-saving in operation. In addition, the air quality of the equipment room 9 is also an important guarantee for the good operation of the magnetic resonance system.
If only the main disinfection and purification machine is provided, the air quality between the facilities is poor. Therefore, the filter screen of the air conditioning system is easy to block, and the surface air cooler is easy to be dirty, thereby shortening the maintenance period and reducing the efficiency of the air conditioner. Secondly, the air quality between the devices is poor, so that dust is easily formed on the magnetic resonance device, and the heat dissipation is poor. Electrical equipment can cause various faults due to heat generation, and the heat generation faults become a main reason for preventing the normal operation of the current electrical equipment. Therefore, the air quality between the equipment rooms is very important, and the air quality is the function of the secondary disinfection and purification machine.
If the main disinfection purifier is not arranged, the air conditioning system cannot be disinfected and purified. Because the air supply and return air of the air conditioning system are not perfectly matched, and the equipment room 9 is not a completely sealed room, the door slot and the window slot can also receive part of air, and the disinfection and purification of the part of air are completed by the main disinfection and purification machine.
The working principle of the invention is as follows: the nuclear magnetic resonance chamber consists of a checking chamber and an equipment room 9, air (return air) of the checking chamber in the nuclear magnetic resonance chamber enters the air mixing box 11 through the return air inlet 5 and the return air pipe 7, namely enters the large cavity 25, part of the air enters the small cavity 24 from the air guide throat 31, then the detection device 36 in the small cavity 24 detects the air, whether carbon dioxide in the air in the checking chamber exceeds the standard or not is judged (the requirement on the content of the carbon dioxide in the air in the checking chamber is met as the standard), the detected air is discharged from the detection gas outlet 37, the air in the large cavity 25 enters the lower cavity 22 through the flow guide hole 26 and then is discharged from the air outlet 28. If the carbon dioxide in the air in the inspection chamber does not exceed the standard, the fresh air valve 39 does not need to be opened, if the carbon dioxide exceeds the standard, the fresh air valve 39 and the fresh air inlet one-way valve 33 are opened, and fresh air is supplemented into the lower cavity 22 by using the fresh air pipe 10, the dehumidifier 18 and the fresh air inlet 27, so that the carbon dioxide content in the air discharged from the air outlet 28 is reduced. In the actual working process, if the subsequent equipment of the air outlet 28 stops working, the air outlet 28 cannot discharge air, and at the moment, air in the inspection room still enters from the return air inlet 29, and due to the effect of the indoor air one-way valve 32, the fresh air valve 39 or the fresh air inlet 33, the incoming air cannot exit from the indoor air inlet 34, the air outlet 28 and the fresh air inlet 27, and then the air can be discharged through the overflow port 30 and the overflow port one-way valve 35, so that the circulation of the air in the inspection room is ensured. Because the air flow discharged from the air outlet 28 basically conforms to the air flow of the return air inlet 29 and the fresh air inlet 27, when the fresh air valve 39 is closed, the indoor air one-way valve 34 at the indoor air inlet 32 is automatically opened to perform secondary disinfection and purification treatment on the air in the equipment room 9. The air from the air outlet 28 is sent to the auxiliary disinfection and purification machine 13 through the connecting pipe 12, and is discharged to the equipment room 9 through the exhaust pipe 14 after being disinfected and purified by the auxiliary disinfection and purification machine 13. The air conditioner 15 sucks air in the equipment room 9 and sends the air into the inspection room through the air outlet 4 by the air conditioner air supply duct 1. If the main disinfection and purification machine 6 does not need to work, the joint of the air conditioning air supply pipeline 1 and the first pipeline 2 is shown in figure 5, if the main disinfection and purification machine 6 needs to work, the driving device (which can be a handle or a motor drive and the like) is used for driving the rotating shaft 16 to rotate 90 degrees, then as shown in figure 4, air enters the first pipeline 2 under the action of the guide plate 40 and the small guide plate 41, and then enters the inspection chamber through the second pipeline 19 and the air supply opening 4 after being treated by the main disinfection and purification machine 6. Because the guide plate 40 and the small guide plate 41 have certain radians, dead angles and places where vortex can be formed do not exist when the air turns, so that the flowability of the air is not influenced, and larger noise is not generated.
The invention has the advantages that: the intelligent disinfection and purification system can intelligently start a disinfection and purification function and a fresh air compensation function according to the environmental air parameters of the nuclear magnetic resonance room, realize the full purification of air supply, fresh air and return air of an air conditioner under the condition of not damaging the magnetic field of the scanning room, and realize the dynamic disinfection of the scanning room in a special place under the condition of human existence. The service time of the air conditioner filter screen is prolonged, and the energy consumption of the air conditioner is reduced. The clean air is beneficial to the good work of nuclear magnetic resonance equipment, reduces the equipment failure rate and prolongs the service life. Avoid the virus cross infection risk between patients and medical staff.
