Electrodeless ultraviolet sterilization apparatus used for sewage treatment plant

Abstract

The invention relates to the field of microwave application, and solves the problem that in the prior art, sterilization cannot be carried out conveniently in a sewage treatment plant. The invention provides electrodeless ultraviolet sterilization apparatus used for a sewage treatment plant, and the apparatus comprises an electrodeless ultraviolet sterilization device and an automatic control device; the electrodeless ultraviolet sterilization device comprises a microwave generation device and electrodeless ultraviolet lamp tubes, wherein the microwave generation device is coupled and connected with the electrodeless ultraviolet lamp tubes through a waveguide system; the wide wall of the waveguide system is provided with aperture structures and resonant cavities; and each electrodeless ultraviolet lamp tube penetrates through one aperture structure through one resonant cavity. According to invention, multiple defects that in a use process of an ultraviolet sterilization system for a sewage treatment plant, treatment of cleaning, sealing, heat dissipation and the like needs to be carried out on quartz tubes, damage occurs easily, and repairing and maintaining are difficult; heat dissipation of the lamp tubes is good, and utilization efficiency of ultraviolet light is improved; the lamp tubes are easier to replace and clean; expandability is high; and sterilization efficiency isadjusted through setting the relation between intensity of the ultraviolet light and the power of magnetrons by using the automatic control device.

Description

technical field [0001] The invention relates to the microwave application field, in particular to an infinite ultraviolet sterilizing device used in a sewage treatment plant. Background technique [0002] There are water purification problems in production and life, and infinite ultraviolet sterilization is already one of the more commonly used sterilization methods; [0003] The sewage treatment of life and production is also closely related to our life. [0004] Various electrodeless ultraviolet lamps and electrodeless ultraviolet sterilizing devices are produced accordingly. Traditional microwave electrodeless ultraviolet lamps usually place all the lamp tubes in a microwave energy resonant cavity with ventilation meshes, and the waveguide transmits electromagnetic waves to excite the lamp tubes. The light tube, although the microwave energy radiates very little in this cavity, can provide sufficient electromagnetic energy for the electrodeless tube. However, the design...
