Embodiment Construction

[0043] In the present invention, the "head" of the guide vane refers to the larger end of the guide vane, and the "tail" of the guide vane refers to the smaller end, which also guides the tip of the guide vane.

[0044] The outer surface 22 of the wing-shaped guide vane refers to the side surface close to the inner wall of the channel, and also refers to the side with a larger curvature; the inner surface 23 of the wing-shaped guide vane is the opposite side of the two surfaces of the guide vane. The other surface of the surface also refers to the side with a smaller curvature. Figure 6 The two curves shown are the side where the outer surface is located and the side where the inner surface is located, that is, the "outer side" and "inner side" in the present invention.

[0045] Specific embodiments of the present invention are given below. It should be noted that, in the description of the present invention, unless otherwise specified and limited, terms such as "setting" and...

Abstract

The invention discloses a built-in wing type multi-air-inlet liquid-inlet jet aerator which comprises an aerator shell, flow deflectors and air inlet pipes, wherein the aerator shell is internally provided with an overflowing channel, the overflowing channel sequentially comprises a circular overflowing channel section, a divergent section and a flat overflowing channel section along the water flow direction, and the cross sectional area of the circular overflowing channel section is smaller than that of the flat overflowing channel section; at least one flow deflector set is arranged in the flat overflowing channel section in the direction perpendicular to the water flow direction, each flow deflector set comprises two flow deflectors, the two ends of each flow deflector are connected with the inner wall of the flat overflowing channel section, and the cross section of each flow deflector is in a wing shape; and an air inlet pipe is nested on the outer side surface of each flow deflector, and vent holes are formed in the air inlet pipes. According to the aerator, the turbulence degree of a flow field can be weakened, the aeration and oxygenation efficiency is improved, and meanwhile, unnecessary loss is avoided.

Description

technical field [0001] The invention belongs to the technical field of environmental equipment, and in particular relates to a built-in airfoil type multi-inlet and liquid jet aerator. Background technique [0002] As the water pollution problem continues to be difficult to solve and water resources are increasingly scarce, aeration and oxygenation technology, as an important way to restore water bodies, is widely used in the environment due to its high energy efficiency, low loss, and simple and easy operation. Engineering water treatment. As the core equipment for oxygenation, the aerator can effectively increase the dissolved oxygen content of polluted water, activate the activity of aerobic organisms, prevent sludge settlement, and ensure full contact between air, sludge and sewage, etc. [0003] For narrow and long terrain environments such as rivers, dams, etc., the flow passages of commonly used aerators are mostly circular, and the gas-liquid mixed water flows evenl...
