部分回流加压溶气气浮法是加压溶气气浮法的一种。

　　

　　传统的加压溶气气浮法的工作原理：依靠水泵将经气浮处理后的净水的一部分回流加压进入溶气罐，同时通过空压机的压力或水射器或压水泵吸水管上的吸力将空气压入溶气，空气在一定的压力条件下溶入水中，然后通过释放器将溶气水压力恢复到常压，释出的大量微细气泡将和原水中的絮粒粘附，而使絮粒被去除。

　　

　　但使用过该种气浮设备的用户都会遇到溶气水不稳定，去除效果不稳定的现象，这主要原因是回流水（洗涤剂太多）与空气在溶气罐中形不成溶气水，而从溶气罐视镜中只看到泡沫，有时溶气罐压力高达0.4Mpa，而释放出来的溶气水不是大的气泡，是细小的小水珠，有时看起来是乳白色的溶气水，而其实是洗涤剂的泡沫，根本达不到净化目的。

　　

　　而JHDF型高效气浮，引进德国进口新技术，将气和回流水经泵进口一起吸入，再经泵的叶轮交切成细小的溶气水，再经过减压阀释放成乳白色的溶气水，使絮凝颗上浮，从而达到净化目的。

　　

　　这种气浮不会因为回流水的洗涤剂太多而造成形不成溶气水的后果，同时也克服了一般气浮所需回流水泵溶气压力，溶气率低的缺点，这是一种新型高效，值得用户信赖可选的气浮。

Part of the reflux gas pressurized dissolved air flotation is one of the types of gas pressurized dissolved air flotation.

Working principle of the traditional gas pressurized dissolved air flotation, rely on the water pump will bullishness of floating part of treated water backflow pressure into the dissolving tank, at the same time, through the pressure of the air compressor or water ejector or pressure pump suction on the suction pipe to the air pressure into dissolved air, under the condition of constant pressure air into the water, and then through the release of dissolved air water pressure returned to normal pressure, will release a large number of tiny air bubbles and flocculated grain of adhesion in raw water, and make the flocculant has been removed.

But used this kind of air flotation system users will encounter dissolved air water is not stable, and remove the effect of unstable phenomenon, the main reason is that the reflux water too much (detergent) with air in the dissolving tank XingBuCheng dissolved air water, but only seen in the dissolving tank sight glass bubble, sometimes dissolving tank pressure up to 0.4 Mpa, and dissolved air water release is not a big bubble, is the tiny water droplets, sometimes looks milky dissolved air water, and the bubble is detergent, never even purification purposes.

And JHDF type high efficiency air flotation, the introduction of Germany import new technology, the suction with the reflux water through the pump inlet gas, then through the pump impeller pay cut into tiny dissolved air water, through the relief valve to release into the milky dissolved air water, make the flocculation floatation, purification so as to achieve purpose.

This gas floating won't because of the reflux water too much detergent XingBuCheng dissolved air water consequences, but also overcome the general gas floating reflux dissolved air pressure pump, the disadvantage of low dissolved air rate, this is a new type of high efficient, trusted user optional air flotation.
