Background technology
Its principle of air supporting machine is to manage to make a large amount of microbubble of generation in the water; To form water, gas and to be removed the three-phase mixtinite of material; Under the acting in conjunction of multiple power such as IT, bubble rising buoyancy and hydrostaticpressure difference; After promoting that micro bubble sticks on the removed tiny oil droplets, because of adherend density less than floating to the water surface on the water, thereby make separated removals such as suspended substance in the water, elaioleucite.
Air-float technology produces the bubble mode by it and mainly can be divided into: the air supporting of gas distribution method comprises the broken gas method of rotor, micropore gas distribution method, impeller dispersed-air flotation etc.; The electrolytic gas float glass process; Dissolved air air supporting comprises vacuum air supporting method, the full air-dissolved of pressure air supporting method, part air-dissolved and partial reflux air-dissolved.
Conventional pressure dissolved air flotation technology mainly is made up of three parts, i.e. pressure air-dissolving system, molten gas release system and dissolved air flotation system.
The pressure air-dissolving system.
Comprise water pump, air compressor machine, pressure air-dissolving tank and other auxiliary facility.Wherein pressure air-dissolving tank is the key equipment that the gas effect is dissolved in influence.The air dissolving system that adopts the air compressor machine plenum system is a present most widely used pressure air-dissolving system.Air supporting method required air quantity is less, and is optional with the little air compressor machine of power, and takes the intermittent operation mode.
Dissolve the gas release system.
Generally form by reliever or perforated pipe, reducing valve and dissolved air water pipeline.The function of dissolved air release be with pressure air-dissolving water through energy dissipating, decompression, the gas that dissolves in the water is discharged with the form of microbubble, and can be quickly and evenly with water in impurity adhere to mutually.
The dissolved air flotation system.
Generally can be divided into three types is flat flow, vertical-flow and composite type.Its function is to guarantee the certain volume and the surface-area in pond, makes flocs unit thorough mixing in microbubble crowd and the water, contacts, adhesion, separates with clear water to guarantee band gas flocs unit.
Summary of the invention
