Malfunctions are a problem.

[0003] Such oil smoke and oil mist also contain dusts such as metal powder, and as a device for separating these impurities from the gas to produce a clean gas, the inertia force due to a sudden change in the flow direction has been conventionally used. Inertial dust collectors such as louver dust collectors used, centrifugal dust collectors such as cyclones using centrifugal force generated by rotational movement, and filters using filter bodies such as woven fabric, filter paper, and fiber packed layer A dust collector is used.

Here, a filter dust collector using a filter such as a woven fabric is a device capable of efficiently separating (dust collecting) impurities contained in a gas, but it is necessary to periodically clean or replace the filter. Is indispensable and has a major problem in terms of maintenance. In addition, inertial dust collectors that use inertial force due to sudden changes in flow direction have a relatively simple structure, many compact objects, and easy maintenance such as cleaning. The re-scattering phenomenon in which the impurities are removed again by the air current is apt to occur, and there is a problem in terms of separation (dust collection) efficiency.
Furthermore, in centrifugal precipitators that use centrifugal force generated by rotational movement, the separation (dust collection) efficiency is higher than that of the above-mentioned inertial precipitators, and many of them are easy to maintain.
There is a problem that the device is generally increased in size.

Can be rotated inside the baffle plate, impurities can be separated from the gas by centrifugal force as well as inertia force, and impurities separated from gas by the action of centrifugal force can be pressed against the wall surface of the baffle plate. It has been found that the separation (dust collection) efficiency is dramatically improved because scattering can be prevented, and the present invention has been completed.

That is, according to the present invention, a wall is disposed with a substantially X-shaped cross section, and a side wall defined by adjacent walls is formed into a curved surface to form a baffle plate member. A plurality of baffle plate members are connected in a staggered manner so that one wall body enters the side wall surface of the adjacent baffle plate member at an appropriate interval to form a baffle plate, and dust and mist are formed on the baffle plate. A separation device for separating / removing impurities from the gas by passing a gas containing impurities such as the above.

According to the separation device of the present invention, since the baffle plate has the special shape described above, a rotational force can be applied to the gas passing through the baffle plate, and centrifugal force such as a cyclone can be generated. Since the used impurities can be separated, a separation device having high separation (dust collection) efficiency can be obtained. In addition, since the structure is similar to that of an inertial dust collector in which a baffle plate is installed in the flow of gas, the advantages of the inertial dust collector, that is, the structure is simple, compact, and cleaning This is a separation device having an advantage that maintenance is easy.

Here, in the present invention, in order to provide a baffle plate capable of imparting a rotational force to a gas that passes through the baffle plate, a top end of each wall of the baffle plate member constituting the baffle plate is provided with: It is preferable to form columnar projections. Also,
When a groove extending in the longitudinal direction is formed on the side wall surface of the baffle plate member, the groove captures impurities in the gas pressed against the side wall surface of the baffle plate member by centrifugal force and guides the impurities downward. In order to achieve the above, it is preferable to provide a device capable of preventing the re-scattering of more separated impurities. Further, the two baffle pieces having the baffle plate members erected alternately are inserted between the baffle plate members erected on one frame piece and the baffle plate members erected on the other frame piece. It is preferable to form the baffle plate by combining the baffle plates in a state in which the baffle plate can be easily manufactured and maintenance such as cleaning can be easily performed. In addition, it is preferable to arrange the baffle plates in a plurality of rows in the gas flow direction, because the separation device has a higher separation (dust collection) efficiency.
