Patent 1: A ceramic material and its preparation method: The invention, an alumina ceramic material and a preparation method of the ceramic material belong to the field of ceramics and its manufacturing, and ceramic materials are added with a certain amount of CoO, MnO2, and Cr2O3 , SiO2, TiO2, respectively, have different effects on the mechanical properties of the material (see the table below for specific usage properties). This ceramic material has low cost and excellent mechanical properties, which can replace cobalt-based materials and is suitable for petrochemical applications.
Patent 2. A simultaneous desulfurization and denitration activated carbon dry flue gas purification device: the present invention relates to a simultaneous desulfurization and denitration activated carbon dry flue gas purification method and device. The flue gas passes through the activated carbon layer for adsorption reaction and is adsorbed qualified. The flue gas is discharged from the other side of the adsorbent activated carbon and slowly moves downward from the top to adsorb harmful gases. The activated carbon, which has adsorbed harmful gases, is heated to precipitate SO2 rich gas under the protection of nitrogen. The SO2-rich gas is sent to acid production or elemental sulfur. The activated carbon after desorption can be recycled. It can remove SOX and NOX in the flue gas at the same time; at the same time, it can also remove other harmful components (hydrogen halides, heavy metals, etc.) and dust in the flue gas, which is more suitable for practical use.
Patent 3. Portable large-displacement synchronous moving pipeline support: The pipeline support is transformed from a traditional fixed rigid support to a swingable type. Greatly extend the service life of the pipeline. Adjustable threaded devices are installed at the connecting positions of the pendulum brackets, which saves time and effort for on-site installation. The pendulum bracket not only has a wider application range than the rolling bracket, but also reduces the amount of steel used and reduces the manufacturing cost. The portable large-displacement synchronously moving pipeline support developed by our company, on the premise of meeting the rigid support required by the pipeline, solves the damage caused by the additional torque caused by the pipeline's thermal expansion and contraction deformation.
