In addition, the inside is composed of small cells (12), the cells 12 are in a straight pipe structure, the cell surroundings is a heat accumulator (13). And since the thermal conductivity is 1 ~ 3W / m ℃, it is 30 ~ 100 times larger than the thermal conductivity of air, and has a large specific surface area of 800 ~ 1000m2 / m3.
또한 상기 세라믹필터(8)는 상기 도3에 도시된 바와 같이, 지지대(9) 상부에 내장되며, 세라믹층(4)과 일정 간격으로 이격되게 설치하고, 콘덕트의 저면과 일정 간격으로 이격되어 설치되도록 구성한다. 이 때 상기 세라믹필터는 상기 도3에 도시된 바와 같이 지지대(9) 상부 전체에 장착되며(세라믹필터의 일부분만을 도시하였음) 지지대(9)는 격자 모양으로 구성되어 상부에 세라믹필터(8)를 적재하며, 세라믹필터(8)를 용이하게 교체나 세척이 가능하도록 지지대(9)에 맨홀(10)이 더 형성되도록 구성된다.In addition, as shown in FIG. 3, the ceramic filter 8 is embedded in the upper portion of the support 9, and is spaced apart from the ceramic layer 4 at regular intervals, and spaced apart from the bottom of the conductor at regular intervals. Configure it to install. At this time, the ceramic filter is mounted on the entire support 9 as shown in FIG. 3 (only a part of the ceramic filter is shown), and the support 9 is formed in a lattice shape to form the ceramic filter 8 on the top. And the manhole 10 is further formed on the support 9 so that the ceramic filter 8 can be easily replaced or cleaned.
상기 세라믹필터(8)의 착탈은 맨홀(10)을 열고 아래로 내려 맨홀(10) 상부에 있는 일부 세라믹필터(8)를 탈착하고, 지지대(9) 상부에 남아있는 세라믹필터(8)는 맨홀(10)을 통해 탈착한다. 세라믹필터(8) 장착은 맨홀(10)을 통해 지지대(9) 상부에 세라믹필터(8)를 장착하고, 분리된 맨홀(10) 상부에 세라믹필터(8)를 장착한 다음 맨홀(10)을 지지대(9)에 체결 함으로서 세라믹필터(8) 장착이 완료된다.The detachment of the ceramic filter 8 opens and lowers the manhole 10 to detach some ceramic filters 8 on the upper part of the manhole 10, and the ceramic filter 8 remaining on the support 9 is manhole. Detach through (10). To install the ceramic filter 8, the ceramic filter 8 is mounted on the support 9 through the manhole 10, the ceramic filter 8 is mounted on the separated manhole 10, and then the manhole 10 is mounted. Mounting the ceramic filter 8 is completed by fastening to the support (9).
상기와 같이 구성된 본 고안의 축열시소각로의 동작 및 작용을 설명하면, 먼저 연소실에서 정화된 고온가스는 세라믹(11)의 B' 에서 B 방향으로 셀(12)내부를 흐르면서 축열부(13)에 열을 축열한다.Referring to the operation and operation of the heat storage incinerator according to the present invention configured as described above, first, the hot gas purified in the combustion chamber flows inside the cell 12 in the direction B to B of the ceramic 11 to the heat storage unit 13. Heat storage
일정시간 후 세라믹(11)의 A 에서 A' 방향으로 저온의 폐가스를 셀(12)내부로 보내면 저온의 폐가스는 축열된 세라믹에 의해 예열된다. 이 때 폐가스 중에 점착성 물질이 함유되어 있으면 셀(12) 내부면에 점착하게 된다.After a certain time, when the low temperature waste gas is sent into the cell 12 in the direction A to A 'of the ceramic 11, the low temperature waste gas is preheated by the regenerated ceramic. At this time, if the adhesive gas is contained in the waste gas, it adheres to the inner surface of the cell 12.
이와 같이 연속운전 시 셀(12) 막힘 현상이 일어날 수 있으나 유입되는 가스온도가 높으면 점착성 물질이 점착성을 상실하게 되어 막힘이 현저히 저하된다.As such, clogging may occur in the continuous operation of the cell 12. However, when the gas temperature is high, the sticky material loses the stickiness and the blockage is significantly reduced.
