Abstract: An environmentally-friendly feed drying and cooling integrated machine, comprising a material drying unit, a material cooling unit and a gas treatment unit, wherein the material drying unit comprises a drying box group (1) and a heating box body module (2); the heating box body module (2) is used for carrying out a drying treatment on materials in the drying box group (1); the material cooling unit is connected to the drying box group (1), receives the materials from the drying box group (1), and carries out a cooling treatment on the materials; two ends of the gas treatment unit are respectively connected to the drying box group (1) and the material cooling unit; the gas treatment unit receives gas discharged from the drying box group (1), carries out a temperature reduction and dehumidification treatment on the gas, and then conveys the gas to the material cooling unit.

Abstract: A material drying and cooling integrated machine, comprising a heating module, a drying module, a dust removal filter module, a temperature-lowering and dehumidifying module, and a cooling module. Dry hot air generated in the heating module can enter the drying module to dry materials; the temperature-lowering and dehumidifying module can conduct temperature lowering and dehumidification on air entering the interior thereof so as to form dry cold air, and the dry cold air can enter the cooling module to cool materials in the cooling module; the dry hot air enters the drying module to dry the materials in the drying module, then damp hot air is formed, and part of the damp hot air can be heated by the heating module again; the other part of the damp hot air can sequentially pass through the dust removal filter module and the temperature-lowering and dehumidifying module, and dry cold air can be formed.

Abstract: An air purification system and air purification method for the dynamic filtering and static sterilization and disinfection of a central air conditioner, the purification system comprising a first sterilization and disinfection purification device (100), a second sterilization and disinfection purification device (200) and an air circulating device. The first sterilization and disinfection purification device (100) and the second sterilization and disinfection purification device (200) respectively control, according to different operation procedures, the opening and closing of valves (101, 201) that are respectively configured. The first sterilization and disinfection purification device (100) and the second sterilization and disinfection purification device (200) each comprise a filtering unit (103), an adsorption barrier unit (104), a static electret unit (107), a sterilization and disinfection unit (105) and an internal air circulating unit (106).
