Low-density fluid generater

The utility model relates to a low density liquid generator, characterized in that the primary air distribution pipe and the liquid inlet pipe are connected to the inlet connection short joint. The primary stirring shell is connected to the inlet connection short joint and the secondary stirring. The inner part of the secondary stirring shell is axially equipped with a nozzle, the air inlet net pipe is arranged on the outlet of the nozzle. The secondary air distribution pipe is connected to the secondary stirring shell. The secondary stirring shell and the outlet connection short joint are connected to the third stage stirring shell, a plurality of spiral stirring block with flow channel are coupled on the connection screw and are fixed on the inner part of the third stage stirring shell, the liquid and the air separately flows into the primary stirring shell through the liquid inlet pipe and the air distribution pipe. The mixture of air and liquid flows into the inner part of the secondary stirring shell through the nozzle after the primary stirring, which is mixed and stirred again with the air flowing through the secondary air distribution pipe, then the mixture of air and liquid flows into the third stage stirring shell, which forms even and stable low density liquid after cutting and mixing of the spiral stirring block and is discharged from the outlet connection short joint.
