An aeration and oxygenation device for river course

Abstract

The invention discloses an aeration oxygen filling device for a river channel. The aeration oxygen filling device comprises a vertical hollow pipe, wherein the upper segment of the vertical hollow pipe is positioned above the water surface of the river channel, and the lower segment of the vertical hollow pipe is positioned below the water surface; the lower segment of the vertical hollow pipe is fixedly provided with a blade, and the upper segment of the vertical hollow pipe is coaxially connected with a conical cylinder through a bearing; the upper end of the conical cylinder is a small end, and the lower end of the conical cylinder is a large end; the surface of the outer side of the conical cylinder is provided with continuous steps from the small end to the large end; one end of a bent hollow pipe is bent to stretch into the vertical hollow pipe from the top of the vertical hollow pipe and is fixedly connected to the inside of the vertical hollow pipe, the bent hollow pipe which protrudes out of the vertical hollow pipe is downwards bent at certain angle and positioned above the conical cylinder, and an opening formed in the upper end of the vertical hollow pipe is sealed; and the outer edge of the large end of the conical cylinder is fixedly connected with the upper end of a support frame, and the lower end of the support frame downwards stretches into the bottom of the river channel and is fixed at the bottom of the river channel. The aeration oxygen filling device disclosed by the invention can achieve the purpose of oxygen filling by only depending on the flow of river water without needing electrodynamic force in an integral aeration process and can be used for uniformly filling the river water positioned on an integral cross section with oxygen.

Description

technical field [0001] The invention relates to an aeration and oxygenation device, in particular to an aeration and oxygenation device used in river courses, and belongs to the technical field of sewage treatment in environmental protection. Background technique [0002] At present, urban and rural rivers are seriously degraded due to pollution and ecosystems, and water environment problems are becoming more and more serious. Most rivers are seriously polluted and eutrophic, resulting in a severe environmental and ecological situation. [0003] Aeration refers to artificially introducing air into the biochemical aeration tank through appropriate equipment, which not only makes the liquid in the aeration tank contact with the air to oxygenate, but also accelerates the transfer of oxygen in the air to the liquid due to the agitation of the liquid, thereby completing the process of oxygenation. Purpose; In addition, aeration also has the purpose of preventing the suspension of...

AI Technical Summary

Problems solved by technology

The quality of the aeration device not only affects the effect of sewage biochemical treatment, but also directly affects the area of ​​the treatment plant, investment and operating costs

[0005] At present, there is no suitable aeration and oxygenation device for the river, because the water volume of the river is large, if the current electric aeration device for the aeration tank is used for aeration, if the aeration is continued 24 hours a day, the aeration cost will be reduced. Power costs will be very high
