Description

Technical Field [0001] The present invention relates to a ceramic filter with a dust-collecting function,

The present invention relates to a ceramic filter, and more particularly, to a dust collectable ceramic filter capable of improving the filtering efficiency by increasing the life of the ceramic filter by performing the function of the ceramic filter before the dust collecting function.

Generally, harmful substances such as dusts, soot, waste gas, smoke, and volatile organic compounds generated in each industrial process are increasingly in serious condition.

Therefore, in order to prevent the emission of pollutants, polymer filters, industrial filters, and nonwoven filters are used. However, since each of the filters has a problem, recently, a ceramic filter is used.

Such a ceramic filter is manufactured by vacuum molding or compression molding of a tube shape using a ceramic fiber and is limited by the size of the ceramic filter that can be manufactured according to the size limitation of the vacuum chamber, There is a problem that a large filter can not be manufactured because it has a size limitation of the filter.

In order to overcome this problem, the conventional ceramic filter manufacturing method is a method of manufacturing a ceramic filter by placing a carrier made of a network or porous structure inside a hollow cylindrical or hollow prismatic frame structure as disclosed in Patent Document 10-1359017, The slurry containing the ceramic powder is injected into the inside of the carrier in a rotated state so as not to be limited in size.

However, in the conventional ceramic filter, there is a problem that the filtering efficiency is lowered due to the foreign substance of the solid matter contained in the filtering object.

In order to solve this problem, a dust collecting device is separately installed before the ceramic filter. However, since dust collecting filtering is required for the entire filtering target object, the inlet space of the dust collecting device is separately required, And the like.

Accordingly, there is an urgent need to develop a technique that not only improves the filtering efficiency but also reduces cost and installation space, as the dust collecting function is performed before passing through the ceramic filter.
