The present application relates to a kind of catalyst for hydrogen chloride oxidation preparation chlorine and its preparation method and application.The preparation method includes: after carrier substrate, metal tantalum powder, binder solution are mixed, extrusion forming is obtained green body, the green body is prepared composite carrier by calcination, the mass fraction of metal tantalum powder in the composite carrier is 5%-30%;Inorganic salt containing catalytically active element is made into solution and is placed in the composite carrier, and after drying, pre-product is obtained, and the pre-product is prepared catalyst by calcination.The preparation method described in the present application prepares high thermal conductivity composite carrier, not only effectively improves the heat conduction efficiency of catalyst, guarantees the effective activity of catalyst, but also guarantees the stability of composite carrier, thereby effectively prolongs the life of catalyst.

A Mylar film bonding mold includes a lower mold with a placement groove on its surface and extension grooves on both sides. A clamping block is disposed within each extension groove. A through hole is provided on the lower mold, and a connecting rod is disposed within the through hole. A limit ring and a pusher are provided on the connecting rod. A cutting blade holder with a cutting head is also provided on the lower mold. The placement groove of the lower mold perfectly matches the dimensions of the sheet metal, allowing for precise fixing of the sheet metal position. The cooperative design of the extension grooves and clamping blocks ensures strict alignment between the adhesive layer of the Mylar film and the edge of the sheet metal through mechanical limiting. The Mylar film and sheet metal are completely aligned and cannot wobble, reducing the occurrence of air bubbles and fuzz on the Mylar film, improving the pass rate, and completely avoiding the offset problem during manual bonding.

The image non-uniformity correction method and device, the infrared image device and the computer readable storage medium provided by the embodiments of the present application, the method comprises: acquiring a same group of in-focus images and out-of-focus images collected for a target scene; respectively decomposing the in-focus images and the out-of-focus images through wavelet transform to obtain corresponding in-focus sub-band images and out-of-focus sub-band images; determining a fixed image noise component contained in a high-frequency component in the out-of-focus sub-band images based on the high-frequency component; determining a corresponding image component estimation value according to a sub-band coefficient of the in-focus sub-band images and the corresponding fixed image noise component; reconstructing the image component estimation value through inverse wavelet transform to obtain a non-uniformity corrected image of the target scene, thus avoiding information loss and redundancy of the image signal in the decomposition process, so that the non-uniformity corrected image of the target scene is obtained more quickly and more clearly.

The present disclosure relates to the technical field of chemical production equipment, and an embodiment of the present disclosure provides a premixing tank for preparing soda from waste sodium sulfate, which comprises a premixing tank, a top cover is fixedly installed at the top end of the premixing tank, and an inclined scraper rod is movably connected to the bottom of the left inner surface of the premixing tank. By arranging the inclined scraper rod, the vertical scraper rod, the horizontal scraper rod, the driven gear and the driving gear, when the first motor is started, the first rotating shaft will drive the driving gear to rotate, because the outer surface of the first rotating shaft is in meshing connection with the outer surface of the driven gear, so under the action of the driving gear, the driven gear will rotate through the round shaft with the horizontal scraper rod, so that the vertical scraper rod and the inclined scraper rod will rotate along the inner wall of the premixing tank with the horizontal scraper rod. In this way, the solid particles adhered to the inner wall of the premixing tank can be cleaned through the cooperation of the inclined scraper rod, the vertical scraper rod and the horizontal scraper rod, thereby solving the technical problem that the solid particles are easily adhered to the inner wall in the prior art.
