Abstract

The invention relates to the technical field of agricultural soilless cultivation, and in particular relates to a plant factory nutrient solution ultraviolet disinfection device. The plant factory nutrient solution ultraviolet disinfection device mainly comprises an outer cylinder, a quartz cylinder and an ultraviolet lamp tube, wherein a baffle plate is arranged between the outer cylinder and the quartz cylinder, and can be used for ensuring that a nutrient solution forms an eddy viscosity turbulent flow in the outer cylinder so as to increase the streaming length and time of the nutrient solution, thus implementing full sterilization and disinfection, improving the ultraviolet disinfection efficiency, and achieving good disinfection effects; the quartz cylinder is arranged in the outer cylinder; a through hole is formed in one end of the outer cylinder, and a clamping groove is formed in the other end of the outer cylinder; one end of the quartz cylinder is positioned in the clamping groove, and the other end of the quartz cylinder is positioned in the through hole, so that the structure is convenient for assembly, disassembly and cleaning of the quartz cylinder; moreover, the disinfection device is simple in structure and convenient in use.

Description

technical field [0001] The invention relates to the technical field of agricultural soilless cultivation, in particular to an ultraviolet disinfection device for plant factory nutrient solution. Background technique [0002] At present, as a modern agricultural high-tech, soilless cultivation has the advantages of greatly expanding the space of agricultural production and facilitating the modernization of agricultural production. Among them, the recycling of nutrient solution has become one of the key technologies for the development of modern soilless cultivation and intelligent plant factories. However, since the nutrient solution will be polluted by various sources of infection during the recycling process, the pathogens of some diseased plants will spread throughout the nutrient solution circulation system, and in severe cases, the entire cultivation system will be paralyzed. It is very important to disinfect the liquid. [0003] Generally, disinfection methods can be ...
