The utility model relates to the technical field of gas turbine power generation, in particular to gas turbine combined cycle power generation low-noise emission equipment which comprises a sound absorption box body, a box door is hinged to one side of the sound absorption box body, and through holes are formed in the two faces of the sound absorption box body respectively. The silencing box body is arranged in the sound absorption box body, an air inlet is formed in one side of the silencing box body, an air outlet is formed in the other side of the silencing box body, and the air inlet and the air outlet are matched with the through holes in the two faces of the sound absorption box body respectively. Compared with the prior art, by arranging the silencing box body, the multistage serially-connected silencing cavities and the complex airflow path, stage-by-stage attenuation, disturbance and dissipation of sound waves are effectively achieved, linear propagation and high-frequency impact of noise are avoided, the noise reduction efficiency is improved, and the noise pollution risk of the system is reduced.

This invention belongs to the field of metal casting equipment technology and discloses an extra-large centrifugal casting mold, including a base assembly; the lower end of a mold assembly is fixedly connected to the base assembly; the upper cover assembly is connected to the upper end of the mold assembly, and the two together form the forming cavity of the casting; the upper cover assembly has a pouring hole; it also includes a rigid constraint frame, which includes multiple longitudinal load-bearing members evenly distributed along the circumference, the lower end of each longitudinal load-bearing member is fixedly connected to the base assembly, and the inner sides of each longitudinal load-bearing member surround and are fixed to the outer circumferential surface of the mold assembly; it also includes multiple sets of thermally actuated clamping mechanisms, which are correspondingly installed on the upper part of each longitudinal load-bearing member; each thermally actuated clamping mechanism includes a driving member arranged radially along the mold and a pressure member connected to the inner end of the driving member; this invention has good rigidity, can effectively adapt to thermal deformation, and has accurate positioning, reliable sealing, and the core vulnerable parts can be quickly replaced.

This invention discloses a highly stable, high-brightness, fast-dissolving, dust-free natural blue composition granules, its preparation method, and its applications, belonging to the field of pigment extraction technology. This natural blue composition uses gardenia blue, butterfly pea flower extract, and phycocyanin extract as the ternary coloring components, compounded with buffers (phosphates) and antioxidants (vitamin C and tea polyphenols), and employs an embedding wall material (β-cyclodextrin and sodium caseinate) for emulsification and embedding. Finally, it is produced into composite granules through spray drying and dry granulation processes. The composition granules exhibit a bright and vibrant color, excellent light and heat resistance, rapid dissolution in water without dust generation, and are environmentally friendly. This invention also provides a method for preparing the composition granules and their application as a colorant in food, pharmaceuticals, and cosmetics, offering a safe, stable, and efficient comprehensive solution to replace petroleum-based synthetic blue pigments.
