[0034] The following will describe a drainage and ventilation system for medical facilities of the present utility model in conjunction with Figures 1 - 3 The drainage and ventilation system for medical facilities includes: a drainage riser 1, an exhaust riser 2, a roof vent pipe 3, and a first air disinfector 4.

[0035] Among them, the drainage riser 1 is connected to each drainage branch pipe 13; the exhaust riser 2 is connected to the drainage riser 1 from beginning to end, and one end where the exhaust riser 2 is connected to the drainage riser 1 is connected to an outdoor inspection well 15; the roof vent pipe 3 is connected to the other end where the exhaust riser 2 is connected to the drainage riser 1, and the roof vent pipe 3 can be switched between a connected state and a disconnected state; the first air disinfector 4 is arranged at one end of the exhaust riser 2 close to the roof vent pipe 3.

[0036] Specifically, the drainage riser 1 collects drainage through the drainage branch pipes 13 arranged on each floor of the building. The gas existing in the water is discharged to the exhaust riser 2. By arranging an auxiliary vent pipe between the drainage riser 1 and the exhaust riser 2, the gas can be discharged to the exhaust riser 2, and the liquid remains in the drainage riser 1.

[0037] During the drainage process, the drainage moves to the outdoor inspection well 15 at the bottom through the drainage riser 1 due to gravity and is discharged from the drainage riser 1. According to the connected state or disconnected state of the roof vent pipe 3, the present utility model has two optional working modes:

[0038] The first working mode is that when the roof vent pipe 3 is in the disconnected state, the exhaust air circulates automatically in the exhaust riser 2 and the drainage riser 1. And during the self-circulation process, it is disinfected by the first air disinfector 4, and the pathogens that may be contained in the exhaust gas are repeatedly killed and eliminated, achieving the effect of not discharging the exhaust gas outside and removing the pathogens in the exhaust riser 2, and finally being discharged to the outdoor inspection well 15. This mode is the self-circulation ventilation mode during the epidemic.

[0039] The second working mode: when the roof vent pipe 3 is in the connected state, the exhaust gas passes through the exhaust riser 2, is disinfected by the first air disinfector 4, and then discharged into the roof vent pipe 3. This mode is the roof venting mode after the epidemic.

[0040] A drainage and ventilation system for medical facilities provided by the present utility model includes: a drainage riser 1, an exhaust riser 2, a roof vent pipe 3, and a first air disinfector 4; the drainage riser 1 is connected to each drainage branch pipe 13; the exhaust riser 2 is connected to the drainage riser 1 from start to end, and one end where the exhaust riser 2 is connected to the drainage riser 1 is connected to the outdoor inspection well 15; the roof vent pipe 3 is connected to the other end where the exhaust riser 2 is connected to the drainage riser 1, and the roof vent pipe 3 can be switched between the connected state and the disconnected state; the first air disinfector 4 is arranged at one end of the exhaust riser 2 close to the roof vent pipe 3. The drainage and ventilation system for medical facilities provided by the present utility model can be switched between the self-circulation ventilation mode during the epidemic and the roof venting mode after the epidemic through the connected state or the disconnected state of the roof vent pipe 3. In the self-circulation ventilation mode, the exhaust gas can be repeatedly disinfected by the first air disinfector 4, with a high pathogen removal rate, reducing the risk of air pollution and epidemic spread; moreover, a first air disinfector 4 is arranged on one side of the exhaust riser 2, which can disinfect the exhaust gas to replace the high-efficiency filter that may cause pressure fluctuations in the pipeline in the prior art.

Specifically, as Figures 1 to 3 shown, the connected state or the disconnected state of the roof vent pipe 3 can be realized by setting a pipe plug 5 or a ventilation cap 6 on the roof vent pipe 3. When in the connected state, the ventilation cap 6 is set to realize the roof venting mode after the epidemic; when in the disconnected state, the pipe plug 5 is set to realize the self-circulation ventilation mode during the epidemic.

[0042] In one embodiment of the present utility model, the drainage and ventilation system for medical facilities further includes: a switch valve 7, and the switch valve 7 is arranged on the roof vent pipe 3.

After the replacement is completed, the first maintenance valves 8 are opened again.

[0044] In one embodiment of the present utility model, the drainage and ventilation system for medical facilities further includes: a second air disinfector 9, which is provided at one end of the drainage riser 1 close to the roof vent pipe 3. As Figure 2 shown, by arranging the second air disinfector 9 on the drainage riser 1, in the first working mode, that is, the self-circulation ventilation mode during the epidemic, the self-circulation gas is disinfected by the first air disinfector 4 and the second air disinfector 9, thereby improving the removal rate of pathogens.

After the replacement is completed, the second maintenance valves 10 are opened again.
