21 open, and compressed air discharges, 161 blowdown apparatus of driven sealed ball float, 161 negative pressure in the drain outlet 16 on tube head 1
It opens, water, oil, the solid particle filtered out by filter core 5 enters pipe shaft 2 by 161 blowdown apparatus 161 of driven sealed ball float, and
It is discharged by the filter sewage draining exit 21 on pipe shaft 2 with the liquid water, oil, solid particle filtered out by gas and water separator 4.This
Device becomes one gas and water separator 4 and high efficiency particulate air filter, and the machines such as centrifugation, gravity, inertia and collision both may be used
Reason is used for removing large quantity of moisture in compressed air, and can be separated using the physical barrier technology of filter core 5 solid in compressed air
The aerosols class impurity such as body particle, water droplet and mist of oil drives it floating from dynamic sealing by the time opening of filter sewage draining exit 21
161 blowdown apparatus of ball, 161 common blowdown, achievees the purpose that water removal, oil removing, dedusting, have occupy little space, parts are few, collection
The advantages that degree is high, and simple in structure and cost is relatively low at changing.
The above, only better embodiment of the invention, but the present invention is not limited to above-described embodiments, as long as
It reaches the technique effect of the present invention with any same or similar means, should all belong to the scope of protection of the present invention.
