Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an improvement of a gas-liquid separation device that separates a mist contained in gas by colliding with a collision plate.

[Prior Art] Conventionally, various types of this type of technology have existed for a long time, and for example, there are technologies disclosed in JP-A-60-34714 and JP-A-60-3970. In all of these, when the collision plate rapidly changes the direction of the gas flow, mist and dust in the gas go straight by inertia and collide with the collision plate to be separated and collected.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technique, although the pressure loss due to the passage of gas is low, the amount of mist once separated is again scattered on the flow of gas. However, there is a problem that the collection efficiency is low.

[Means for Solving Problems] The present invention has been devised in view of the above problems, and includes an air intake pipe for introducing gas containing mist into a cylinder, and an air intake pipe facing the air intake pipe in the cylinder. In a gas-liquid separation device including a deployed collision plate, a collective guide provided on a surface of the collision plate that faces the air inlet pipe, and an exhaust pipe that discharges gas in the cylinder from the back surface side of the collision plate. The above-mentioned problem is solved by a gas-liquid separation device characterized in that the collecting guide has a surface that is substantially orthogonal to the collision plate and is inclined in the direction of gravity.

[Operation] According to the configuration described above, the mist that collides with the collision plate and is separated flows down the collision plate and reaches the collecting guide. Since this collective guide is substantially orthogonal to the collision plate, the mist that has flowed along the collision plate is first received by this collective guide, and subsequently its surface is inclined in the direction of gravity, The flow of each mist merges and collects near the inner wall surface of the cylinder. As a result, each mist aggregates into a mist of large particles and falls from the collection guide by its own weight. Thus, the separated mist does not scatter along with the gas flow, so that the mist collection efficiency can be improved without increasing the pressure loss when the gas passes.

[Embodiment] A preferred embodiment of the gas-liquid separator according to the present invention will be described in detail with reference to the accompanying drawings.

Reference numeral 1 denotes a closed cylindrical body, which is formed in, for example, a cylindrical shape or a rectangular parallelepiped shape. Reference numeral 2 is an air intake pipe for introducing the gas 4 containing the mist 3 into the cylindrical body 1, and is connected to the upper side wall of the cylindrical body 1. Reference numeral 5 denotes a collision plate, which is arranged above the inside of the cylindrical body 1 so as to face the intake pipe 2. On the surface of the collision plate 5 facing the intake pipe 2, a substantially mountain-shaped collecting guide 6 is arranged to collect the mist 3. An exhaust pipe 7 is connected to the back side of the collision plate 5 above the side wall of the cylinder 1 to discharge the gas 4 in the cylinder 1. Further, a valve 8 for discharging the collected mist 3 is connected to the bottom of the cylindrical body 1.

Next, the operation of the above configuration will be described. The gas 4 containing the mist 3 such as oil is introduced into the cylindrical body 1 from the air inlet pipe 2 and is rapidly changed in direction by the collision plate 5. Therefore,
The mist 3 is separated from the gas 4 and drops onto the collecting guide 6. Further, the gas 4 passes under the collision plate 5 and is discharged from the exhaust pipe 7.

As shown in FIG. 3, the mist 3 that has fallen is collected by a gathering guide 6
It collects in the vicinity of the inner wall surface of the cylinder 1 along the top and falls by its own weight. Thus, the mist 3 separated from the gas 4 does not scatter along with the flow of the gas 4.

Further, the mist 3 collected in the cylindrical body 1 is discharged by opening the valve 8.

[Advantages of the Invention] As described in detail above, according to the present invention, since the assembly guide provided on the collision plate has a surface that is substantially orthogonal to the collision plate and is inclined in the direction of gravity, The mist that has flowed along can be received by the gathering guide, and can be merged and collected by the inclined surface of the gathering guide. As a result, each mist aggregates and becomes a mist with large particles that fall by its own weight from the assembly guide, so the mist does not fly along with the flow of gas and increases the pressure loss when gas passes. Without this, it is possible to improve the collection efficiency of mist, and it is suitable for deployment in an exhaust gas treatment device of a vehicle.
