According to the deodorizing, ventilating and disinfecting method for the livestock-raising shed based on adsorption filtration, the filter screen 26 arranged by the blowing fan 6 or the suction fan 11 is used for deodorizing, the first filtering mechanism 7 is used for absorbing, deodorizing and deodorizing at a gap with the second filtering mechanism 12, and the ultraviolet lamp 17 is used for sterilization treatment, so that harmful germs are prevented from polluting the air of the shed, the problem that the traditional breeding shed pollutes the surrounding environment is solved, the surrounding air quality is improved, and the air quality in the breeding shed is improved; the heat exchange cooling fins 8 and the heat exchange condensing fins 13 are opened, hot air in the shed enters the air outlet cavity 4 from the air exchange inlet 10, is liquefied by the heat exchange condensing fins 13 and then releases heat, the heat is transferred to the heat exchange cooling fins 8, and the heat is blown into the shed through the air inlet cavity 3, so that the heat loss of the shed is reduced, and the shed can be kept at a proper temperature; the water liquefied by the heat exchange condensation sheet 13 is collected by the collection box 14 and is connected with the atomizing nozzle 15 to humidify the air in the air inlet cavity 3, so that a good humidity environment in the shed is maintained, the environment in the breeding shed is kept in a state of relatively constant temperature and humidity, the occurrence of livestock diseases is reduced, the energy is saved, and the breeding cost is saved; through the relation between the air temperature in the restriction cowshed, the air temperature outside the cowshed, the supply-air flow of new trend export 9, further reduce the cowshed heat and scatter and disappear, do benefit to the cowshed and keep suitable temperature.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention; any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
