Abstract

The utility model discloses an efficient aerator, which comprises a bracket and a jet aerator arranged on the bracket; an air inlet end of the jet aerator is communicated with a blower through an air tube; a water inflow end of the jet aerator is communicated with a jet-flow circulating pump through a pipeline; jet pipes are arranged on the two sides of the jet aerator; and each jet pipe has an inclination angle of 45 degrees with the horizontal plane. The aerator has the advantages of simple structure, no need for maintenance and sealing, and high oxygen transfer efficiency.

Description

A kind of high-efficiency aerator
Technical field
The utility model relates to a kind of waste disposal plant, particularly a kind of high efficient aeration device.
Background technology
Percolate is acknowledged as in the water treatment field one of the most unmanageable waste water always, percolate ammonia nitrogen concentration height, biochemical treatment A/O technology is carried out denitrogenation exactly, and in nitrifying process water being carried out high efficiency oxygenation is the key of handling, and higher dissolved oxygen can improve nitration reaction speed.Use deep water air pressing type aerating apparatus now mostly, this device is that a blower unit is installed on ground, be connected by the inlet pipe in the floating drum center on inlet pipe and the water surface, inlet pipe is connected with the wind box shell, and lower part outlet is connected with gas skirt, adorns a submersible machine in the inlet plenum, its dispersion wheel stretches in the gas skirt with holes, reach the effect of aeration, but its physical construction more complicated, the maintenance of underwater operation part is trouble.
The utility model content
Goal of the invention: at the deficiencies in the prior art, the utility model has designed a kind of simple in structure, the high efficient aeration device of being convenient to safeguard.
Technical scheme: the utility model discloses a kind of high-efficiency aerator, comprise support, be arranged on the ejector on the support, the inlet end of ejector is communicated with by tracheae and gas blower, and the feed-water end of ejector is communicated with by pipeline and jet recycle pump; The ejector both sides are provided with jet pipe, and jet pipe and horizontal plane are 45 ° of inclinations.
During use, air water mixes in ejector, is penetrated by jet pipe, plays the aeration effect.
Described ejector is an one-block apparatus, does not have the active part, and material is PP, and is corrosion-resistant, non-maintaining, exemption from inspection.Ejector need not sealing, and when aerator was out of service, water can enter tracheae, and aerator and airing system are not had negative impact, because when restarting, injector can form negative pressure in tracheae one side, extracts endotracheal water out aerating apparatus.Ejector designs according to the rheological properties of active sludge, has reached a suitable air water ratio.
High biochemical oxygen demand (BOD) based on high concentration organic sewage, and in height growing of modern sewage biochemical treatment facility, with mechanical means the pressure of air is brought up to the hydrostatic of ejector installation site in advance, and be transported to air-breathing junction, it is more effective to say so from energetics, simultaneously, vapour-liquid ratio also improves.The dynamic medium jet has become air many trickle bubbles under low power, this air-water mixture is ejected into the bottom, aeration tank intensely, has guaranteed the thorough mixing of the inclusion in fine oxygen transfer and the aeration tank.Even under the very high situation of the dried solid matter content in sewage, also can keep flow velocity, prevent that solid matter from sinking to the bottom.
Beneficial effect: the disclosed high-efficiency aerator of the utility model, simple in structure, need not maintenance, need not sealing, the oxygen transfer efficiency height.
Description of drawings
Accompanying drawing 1 is the structural representation of high-efficiency aerator.
Embodiment
The utility model is further explained below in conjunction with accompanying drawing.
The utility model discloses a kind of high-efficiency aerator, comprise support 1, be arranged on the ejector 2 on the support 1, the inlet end of ejector 2 is communicated with by tracheae and gas blower 3, and the feed-water end of ejector 2 is communicated with by pipeline and jet recycle pump 4; Ejector 2 both sides are provided with jet pipe 5, and jet pipe 5 and horizontal plane are 45 ° of inclinations.
Sewage and air enter ejector by jet recycle pump and gas blower respectively, and air acutely mixes with sewage, and air is ground into extremely small bubble; Subsequently, through the ejector diffusion time, micro bubble further is compressed, and forms dissolved air water, from the ejection of the jet mouth of pipe, produces violent turbulences effect in the aeration tank, and a large amount of oxygen in water, are finished the efficient transfer of oxygen with trickle gas bubble.
The utility model provides a kind of thinking and method of high-efficiency aerator; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, and all available prior art of each integral part not clear and definite in the present embodiment is realized.
