AI Technical Summary

Problems solved by technology

[0048] Based on the structure of the CN102260003A scheme, the electrodeless ultraviolet lamp is placed in the lumen of the quartz tube. In order to ensure the normal luminous work of the electrodeless ultraviolet lamp, the inner wall of the quartz tube must be kept clean to maintain the permeability to ultraviolet light. Moreover, based on similar light permeability requirements, the outer side of the lamp wall of the electrodeless ultraviolet lamp involved must also be kept clean; however, the structure of the CN102260003A scheme is difficult to avoid the problem of water inrush in the lumen area of ​​the quartz tube The so-called water inrush in this case refers to the unwelcome water in the reactor protruding into the lumen area of ​​the quartz tube; there are generally two reasons for the water inrush: one is the quartz tube The thermal expansion and contraction of the air in the cavity area leads to underpressure in the lumen area of ​​the quartz tube, and the second is that the air in the lumen area of ​​the quartz tube escapes and causes underpressure in the lumen area of ​​the quartz tube. In this way, driven by the relative positive pressure of the surrounding water body, The water in the reactor gradually breaks into the lumen area of ​​the quartz tube, forming a water inrush situation; when the air pump is powered off and the outer surface of the quartz tube is partially or mostly submerged in water, the outburst is especially prone to occur. Water conditions; specifically, the most likely period for this water inrush problem is the following two periods, the first period is when the wastewater to be treated is filled into the reactor and the air pump has not been started, and the second period is After the air pump is turned off and the water extraction procedure has not been completed; when the water inrush situation occurs, the water mixed with many inorganic impurities protruding into the lumen of the quartz tube can easily contaminate the inner wall of the lumen of the quartz tube and the electrodeless ultraviolet lamp The outer surface of its own lamp wall leads to a significant decrease in the ultraviolet light transmittance of the relevant light-transmitting structural parts, which in turn affects the overall wastewater photodegradation treatment efficiency of the relevant wastewater degradation reactor. Therefore, the problem of water inrush should not be avoided. This is Question sixteen
