[0002] In modern hospitals, the medical central suction system is an essential equipment. It is generally connected to a vacuum tank through a vacuum pump. The suction of the vacuum pump creates negative pressure in the suction system pipeline, thereby generating suction at the terminals of the operating room, emergency room, treatment room and each ward for medical use.

[0004] However, the existing steam-water separator has a simple structure and low separation efficiency. When the water content in the gas is high, the separation effect of the steam-water separator is poor, which affects the work efficiency and reduces the performance of the machine. Utility Model Content

[0007] The dehumidifier shell has a plurality of connection blocks arranged on its upper surface and an air outlet opened on its upper surface.

[0008] Preferably, the diameter of the upper end of the air inlet pipe is larger than the diameter of the lower end, and a third baffle is provided at the lower end of the air inlet pipe. There is a gap between the lower end of the air inlet pipe and the third baffle. The third baffle is a square plate structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model proposes a steam-water separator for a central suction system, in which gas flows in through an air inlet pipe and enters a gradually narrowing internal pipe. As the channel becomes narrower, the gas flow rate increases and sprays downward to impact the third baffle and the second baffle. During the gas flow, water vapor is separated from the gas due to inertia, adheres to the third baffle and the second baffle and condenses into water droplets, and is finally discharged through the water outlet pipe. The gas enters the next chamber through the opening above the second baffle, passes through the porous structure on the water vapor capture plate, removes most of the water vapor and condenses into water droplets, and is finally discharged through the water outlet pipe. Subsequently, the gas enters the connecting pipe through the air inlet on the partition, and is discharged into the dehydrator shell from the air outlet. The motor drives the rotating shaft and the fan to rotate, and the fan rotates the gas. The water vapor adheres to the inner wall of the dehydrator shell and the first baffle with the action of centrifugal force and condenses into water droplets, which are finally discharged through the water outlet pipe.
