BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector, and more particularly, to a dust collector for removing moisture contained in fine dust together with fine dust.

Generally, a dust collector is used in order to prevent environmental pollution caused by exhaust gas, fine dust, and industrial waste discharged during manufacturing or processing in a manufacturing factory such as cement, textile, have.

On the other hand, when cutting a metal material, a water-soluble cutting oil diluted with water and a stable emulsion form is used as a stock solution in which a base oil and a surfactant are combined to impart lubricity and coolability.

In this way, when fine dust is removed by a dust collector using a water-soluble cutting oil in the field, the fine dust is removed by a filter provided inside the dust collector, but the moisture introduced into the dust collector together with the fine dust is completely removed by the filter Do not.

As a result, as moisture is sprayed through the outlet of the dust collector in the form of mist, an anxiety about the filtering efficiency of the dust collector may occur.

In addition, since moisture adheres to the filter by aggregating the fine dust in the course of filtration by the filter, the filtration performance is lowered and the filter life is shortened.

In order to solve such a problem, Patent Document 1 and Patent Document 2 described below disclose a technique for removing moisture introduced into a dust collector.

Patent Document 1 discloses a case having a dust suction inlet through which dust is sucked and a dust discharge port connected to the suction port of the filter dust collector; A partition member that divides the inside of the case into a suction chamber communicated with the dust suction port, a discharge chamber communicated with the dust discharge port, and a cooling chamber between the suction chamber and the discharge chamber; A communicating means for forming at least one conveyance passage in the cooling chamber for communicating the suction chamber and the discharge chamber; And a cooling gas supplying means for supplying a cooling gas to the cooling chamber to condense the steam introduced into the transfer passage together with the dust.

Patent Document 2 discloses a dust collecting apparatus comprising: a housing having an inlet formed at one side thereof for supplying high-temperature dust and steam, an outlet formed at the other side for discharging dust to the dust collector; A cooling plate installed inside the housing to cool the steam; And a condensation filter installed inside the housing to further cool and condense the steam passing through the cooling plate and to increase the flow velocity.
