8. A method of air purification in a multi-person ward air purification system as set forth in any one of claims 1 to 7, comprising the steps of:

step 1, collecting dirty air: the first fan sucks the dirty air at the top of the ward into the first air collecting main pipe through the first air collecting branch pipe; the second fan sucks dirty air at the bottom of a ward into the second gas collecting main pipe through the second gas collecting branch pipe, when a filter screen on the second gas collecting branch pipe is blocked, the pressure difference sensor senses that the pressure difference exceeds a set value, the first control module of the anti-blocking mechanism controls the first motor to rotate forwards, the first motor drives the garbage removing cylinder to rotate forwards by 180 degrees through the connecting rod, the garbage removing cylinder scrapes garbage on the filter screen and pours the garbage into the garbage can through the pouring port, then the first control module controls the first motor to rotate reversely, and the first motor drives the garbage removing cylinder to rotate reversely by 180 degrees through the connecting rod to complete resetting; the fourth fan sucks the dirty air in the first gas collecting main pipe and the second gas collecting main pipe into the gas collecting hood;

step 2, disinfecting and dedusting the polluted air: the first water pump pumps out the disinfectant and sprays out through the main spray head and the auxiliary spray head; the main spray head sprays disinfectant to the dirty air in the gas-collecting hood, and the disinfectant adsorbs dust in the dirty air and kills germs in the air; the air sprayed by the main spray nozzle flows out of the gas collecting hood from the gas exhaust port, and the auxiliary spray nozzles spray disinfectant on the air flowing out of the gas exhaust port to perform secondary disinfection and dust removal on dirty air; the fifth fan sucks the air subjected to secondary dust removal into the first air dispersion main pipe and the second air dispersion main pipe, and disinfectant in the air is removed by disinfectant removing mechanisms in the first air dispersion main pipe and the second air dispersion main pipe; when the liquid level of the disinfectant in the first disinfection box is higher than the top end of the first bent pipe, the disinfectant flows out of the first bent pipe; when the liquid level of the disinfectant in the first disinfection box is lower than the bottom end of the gas collecting hood, the floating block and the sliding rod in the liquid level box move downwards, the liquid outlet is in an open state, and the disinfectant in the second disinfection box flows into the liquid level box through the liquid inlet pipe, the fixing pipe and the liquid outlet and flows into the first disinfection box from the liquid level box;

step 3, air humidification: the heater of the humidifying mechanism heats and evaporates water in the heating barrel, water vapor is generated in the heating barrel, and the sixth fan conveys the water vapor to the first main air diffusing pipe through the exhaust pipe; when the liquid level sensor senses that the liquid level in the second bent pipe is lower than a set value, the second control module controls the first electromagnetic valve to be opened, the second water inlet pipe adds water into the heating barrel, and after the first electromagnetic valve is opened for a set time, the second control module controls the first electromagnetic valve to be closed;

and 5, generating an air curtain by air and circulating: the air curtain machine sucks the air in the second air diffusion main pipe and blows the air out of the air outlet, and the air forms an air curtain to isolate the sickbed; air blown out by the air curtain machine enters the return tank from the air inlet and flows into the second gas collecting main pipe; and (5) circulating the processes of the steps 1-5, and continuously purifying the air in the ward.
