Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The present embodiment relates to a honeycomb ceramic carrier, which is shown in fig. 1 and 2 in combination with fig. 3 to 8, and includes a housing 1 having an exhaust gas inlet 101 and an exhaust gas outlet 102, and a core provided in the housing 1 to separate the exhaust gas inlet 101 and the exhaust gas outlet 102. Structurally, in the present embodiment, the housing 1 is a hollow cylinder structure with an open top, the detachable end cover 2 is disposed on the top of the housing 1, the end cover 2 forms the open plug, the exhaust outlet 102 is formed on the bottom wall of the housing 1 and disposed on the same center line as the housing 1, the exhaust inlet 101 is formed on the end cover 2, and the exhaust inlet 101 is located outside the second annular partition plate 4 on the outermost layer described below and located inside the side wall of the housing 1 and disposed annularly, so as to prevent the exhaust from being directly discharged from the exhaust outlet 102, in the present embodiment, the end cover 2 is disposed along with the housing 1, and can be screwed to the housing 1 through bolts.

The core body in this embodiment includes a plurality of annular partition plates arranged in series at intervals in the radial direction of the casing 1, the annular partition plates being arranged concentrically with the casing 1 and made of ceramic, and each of the annular partition plates is formed with at least one intake gap, while being coated with a catalyst, and the annular partition plates are formed with honeycomb holes, not shown in the drawings. In this embodiment, the annular partition plate includes the first annular partition plate 3 that links firmly on the casing 1 diapire to and link firmly the second annular partition plate 4 on the end cover 2, because of the casing 1 is located to the end cover 2 lid, this second annular partition plate 4 alternates in the interval that two adjacent first annular partition plates 3 formed.
