The present invention relates to a ceramic filter assembly and a method of assembling the ceramic filter assembly so that the coupling member is not exposed to the outside, in particular, the venturi and the upper cap, so that the external appearance of the ceramic filter assembly is excellent.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceramic filter assembly and a method for assembling the ceramic filter assembly, which facilitate maintenance, maintenance and repair by making the direction of joining the inner fastening member and the outer fastening member different.

The present invention relates to a ceramic filter assembly having an elastic member on an inner fastening member to facilitate assembly and easy assembly.

As the industry develops, hazardous substances such as dust, soot, waste gas, smoke, and volatile organic chemicals (VOC's) generated in each industrial process are increasing. Therefore, in order to prevent the emission of such pollutants, a polymer filter is used in some cases, but in the case of a polymer filter, there is a problem in that it is poor in heat resistance, chemical resistance, abrasion resistance and flame retardancy.

In other words, polyester shrinks at 150 ° C, and PTFE (Teflon), which has excellent heat resistance, has only heat resistance of up to 250 ° C. The atmosphere of the process using industrial filters is dust, various kinds of waste gas, The nonwoven filter of most polymer materials, such as polyester, polypropylene, acrylic, polyamide, polyimide, glass fiber, etc., is a harsh environment that occurs at the same time. When the dust attached to the filter surface is shaken by jet pulse method, As the dust is falling, the surface of the filter is very abrasive due to the dust, which damages the filter and shortens the period of use of the filter. In addition, if the flame is generated during the combustion process of each industry and the filter is attached to the filter, , A hole in the filter, a waste incinerator, a boiler, a coal-fired power plant, a coal gasification complex In the case of power generation, since there is a risk that the exhaust gas is exposed to the atmosphere, there is a problem that it is backed by the environmental regulation to be reinforced.

 Therefore, ceramic filters have been developed to solve these problems. Ceramic filters are superior to polymer filters in heat resistance, chemical resistance, abrasion resistance, etc. In particular, they are excellent in heat resistance, There is an advantage that the installation cost and the maintenance cost can be reduced.
