The condensed water that separates will flow to the outlet of blower obliquely along the curved wall of air blast hood, and the water by breach flows into discharge chamber during this period, as mentioned above, and the opposite direction of this breach directed towards air stream.
Remove from blower in order to ensure the condensed water that obtains by discharge chamber, can place perforated plate along a zone of extending from discharge chamber, this perforated plate is at the blower export that extends upward or recline on the blower curved outer wall, and above-mentioned perforated plate defines a discharge passage that enters discharge chamber with outer wall.
Under the interference of the air-flow that passes through, be not discharged the condensed water that the chamber obtains as yet and enter discharge passage, after this in the discharge chamber below this passage of action of gravity lower edge flows into downwards by the hole on the perforated plate.
In order to prevent to produce rightabout air-flow in discharge passage, this air-flow is understood the gravity of influence on condensed water, and preferred design flow resistance device on discharge passage, this device can be the silk screen that is inserted in this passage as an example.
In addition, between two discharge passages, can be provided with a dividing plate, discharge chamber is divided into first portion and second portion, flows through first portion from the condensed water of the rightabout breach of directed towards air stream direction, the condensed water that does not flow out by breach that points to flow direction flows out from second portion.Flow out corresponding discharge chamber by the condensed water that makes separation by their outlet, this rightabout condensation flow can be separated in discharge chamber effectively, and air-flow can not have a negative impact to the gravity that acts on the condensed water.
Obviously, turbo charging installation of the present invention can be removed the water of condensation effectively from the scavenging of supercharging and cooling, and these scavengings are on the two-stroke diesel engine that is fed in the work as an example.
In addition, when between the outlet of centrifugal blower inlet and intercooler, inserting an independent separator, can obtain added security, can prevent that the condensed water with scavenging from entering the cylinder of corresponding motor.
