Device for removing riverway floating oil through solar energy photolysis

Abstract

The invention discloses a device for removing riverway floating oil through solar energy photolysis. The device comprises a support, a body, a solar cell panel and a storage battery. The body is erected on the support and movably connected with the support, the solar cell panel is arranged above the body, and the storage battery is electrically connected with the solar cell panel. The body comprises a hollow barrel, a sealing cover and multiple blades. Ultraviolet tubes electrically connected with a positive electrode and a negative electrode of the solar cell panel and a positive electrode and a negative electrode of the storage battery are arranged in the hollow barrel. The outer surface, covered with an oleophilic layer, of the hollow barrel is provided with axial grooves with through holes formed in the bottoms, the through holes stretch inwards in the radial direction to form hollow conical barrels with holes formed in the tops, the bottoms of the hollow conical barrels are arranged on the inner wall of the hollow barrel and provided with open holes right opposite to the corresponding through holes, and the side wall faces, irradiated by the ultraviolet tubes, of the hollow conical barrels are covered with photocatalytic materials. At least one openable sealing cover covers the two ends of the hollow barrel. The blades protrude outwards in the radial direction from the outer surface of the hollow barrel. No power device is needed, and the device is high in oil removal efficiency, simple in structure, low in price, convenient to use and low in maintenance cost.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a device for removing slick oil from rivers by using solar photolysis. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. Urban and rural rivers are severely degraded due to pollution and ecosystems. The water quality of the rivers is basically at the V or inferior V level. Most of the rivers are seriously polluted, eutrophic, lack of oxygen, black and smelly, resulting in a severe environmental and ecological situation. In addition, due to river shipping leakage or illegal discharge by coastal enterprises, more and more oil pollution is floating on the surface of the river. In recent years, oil pollution has always been a major problem in river treatment and management due to its difficulty in cl...

Problems solved by technology

In principle, there is nothing wrong with this collection method. The only thing that is difficult to guarantee is that the draft of the bell mouth cannot match the flow rate of the pump. If the draft is too shallow, the center of the bell mouth will form a vortex to suck in air and damage the pump; if If the draft is too deep, there will be more water and less oil in the oily sewage, which will lose the meaning of collecting oil slicks. Therefore, the use of this collection device has certain limitations. When the flow rate of the water pump is determined, the draft of the bell mouth is relatively determined. For still water, it is more convenient to use, but for more volatile water, the situation is completely different

Moreover, the water pump needs a motor for power, which has the problem of energy consumption, and the equipment is relatively heavy, so it is not suitable for long-term maintenance of large-area river water surfaces.
