The invention is an improved surface aeration impeller for use in a liquid filled tank which particularly increases the surface turbulence and the entrainment of gas into the liquid surface. The impeller is an axial flow impeller and may be either a pitched blade turbine (PBT) or have airfoil shaped blades. In either case, the impeller has a portion which extends radially along an edge thereof which projects above the surface of the liquid being mixed in a vertical direction. The blades of the impeller are modified to include a top horizontal plate to lower the spray height of the liquid and an optional endcap, both of which can enhance and increase the standard aeration efficiency. Preferably, the impeller is rotated in an up-pumping direction and propels the liquid being aerated in a radially upward and outward direction. A sufficient upward surge of liquid is produced so that the liquid is observed to splash back onto the surface a plurality of times in the course of operation of the impeller. Such multiple splashing action enhances the contact between the air and the liquid itself to improve the oxygen transfer efficiency of the aeration impeller.

The invention includes a spraying device (10) for producing a precise degree of liquid droplet generation on a repeatable basis by combining a specified rate of regulated flow of liquid material with a regulated flow of high-pressure air. The spraying device (10) includes an electric or engine driven direct drive compressor (12). Coupled to the compressor (12) is an air storage tank (14) providing air pulsation reduction to the regulated air and serves as a reservoir for excess airflow generation. A Venturi nozzle (18) is connected to the compressor (12). A liquid supply tube (24) uses a fixed or variable restriction to regulate the liquid flow to the nozzle (18). The vacuum in the liquid supply line (24) draws this liquid flow and mixes the liquid externally with the regulated air in exacting proportions forming specified liquid droplet sizes. The device (10) uses air and liquid regulation combined with a Venturi nozzle (18) and is able to generate extremely consistent liquid droplet sizes.

Since the inner diameter of a flow-contracting portion continuously decreases toward a cylindrical swirl chamber, the velocity of flow of washing water flowing in the flow-contracting portion continuously rises. Since the inner diameter of the flow-contracting portion continuously decreases toward a spray hole, the velocity of flow of the washing water flowing in the flow-contracting portion continuously rises. Washing water supplied to one of flow paths in a two-flow path pipe is supplied to a flow path merger through a one-flow path pipe. The washing water supplied to the other flow path in the two-flow path pipe is supplied to the flow path merger after passing through a space between the one-flow path pipe and a nozzle cover. Washing water sprayed from a nozzle cleaning hole flows out of an opening at a front end of a nozzle cleaning cylinder along an outer peripheral surface of a piston while being spirally swirled in a space between an inner wall of the nozzle cleaning cylinder and the outer peripheral surface of the piston. A position fixing member having a curved shape along an inner surface at a front end of the nozzle cover is formed at a front end of the flow path merger. While a posterior nozzle moves from a forward position to a backward position, dispersed spiral flow and linear flow are alternately sprayed.
