The present invention provides an SCR catalyst and a preparation method therefor and a use thereof. The SCR catalyst comprises a flow-through ceramic honeycomb carrier and a first coating layer. The first coating layer is coated on the pore channel surface of the flow-through ceramic honeycomb carrier. The first coating layer comprises a Mn / Cu-SSZ type first molecular sieve, a cerium oxide, an aluminum oxide, and a manganese oxide. The preparation method for the modified SCR catalyst provided by the present invention has a simple process. After being hydrothermally aged at 800°C, the obtained catalyst still has excellent denitration performance in a low temperature range of 150-200°C without losing denitration performance in a medium-high temperature range of 250-500°C. The catalyst can achieve good NOx conversion over a wider operating temperature window.

This utility model discloses a hollow high-strength ceramic tile, relating to the field of ceramic tiles, including an upper surface layer and a lower surface layer; an intermediate support mechanism connecting the upper and lower surface layers, the intermediate support mechanism being configured in a honeycomb shape; a surrounding plate fixed to the outside of the intermediate support mechanism, a connecting block fixedly connected to one side of the surrounding plate, and a connecting groove opened on the other side of the surrounding plate, the connecting block and the connecting groove being positioned correspondingly; the intermediate support mechanism being configured in a honeycomb shape, the intermediate support mechanism being high-alumina ceramic or zirconia toughened ceramic, the honeycomb structure not only reduces the overall weight of the tile, but also provides sufficient strength and stability, while providing space for the filling of lightweight heat insulation material, further improving the heat insulation performance of the tile, and the geometry of the honeycomb structure can effectively disperse stress, providing high strength and good compressive strength.

This invention relates to the field of waste gas treatment equipment technology, and discloses a regenerative thermal incineration waste gas treatment device, including a support frame. Three regenerative chambers are fixedly connected to the top of the support frame, and a common combustion chamber is fixedly connected to the top of the three regenerative chambers. This invention addresses the problem of local overheating and thermal shock cracking of ceramic honeycomb. An auxiliary mechanism and a pressure mechanism are set inside the device. After the waste gas is purified, a hydraulic press pushes a hydraulic push rod upward, which in turn moves the highest fixed frame two upward. As the hydraulic push rod continues to move upward, the six fixed frames two will separate, and the air inlet pipe will generate a negative pressure suction force, forcing the purified high-temperature gas in the common combustion chamber to flow downward and heat the honeycomb ceramic two and honeycomb ceramic one. This causes multiple sets to separate, allowing the oxygen remaining inside the honeycomb ceramic one and honeycomb ceramic two to diffuse outward at once, while reducing the length of the "combustion channel" and effectively reducing the probability of combustion and explosion.

This invention discloses a high-temperature resistant microwave absorbing honeycomb ceramic, its preparation method, and its applications, relating to the field of porous ceramic materials technology.
