A second channel outlet of the heat exchanger communicates with the heat pump assembly, the heat exchanger provides a cold water source for the heat pump assembly, and the heat pump assembly supplies a generated high-temperature heat source to the heat exchanger; a water vapor outlet in the top of the evaporation tower is communicated with an inlet in the bottom end of the condensation tower. The low-temperature normal-pressure evaporation technology and the heat pump technology are combined, waste heat and waste heat are used for supplementing heat for the low-temperature normal-pressure evaporation technology, and low-energy-consumption operation of power plant salt-containing wastewater treatment is completed.

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.

The pressure reducing assembly comprises a pressure reducing valve assembly body and a split type output end cover, the pressure reducing valve assembly body is fixedly connected with the gas cylinder, a gas outlet channel is formed in the pressure reducing valve assembly body, and a jacking structure is arranged on the inner surface of the split type output end cover. When the split type output end cover and the pressure reducing valve assembly are installed in a matched mode, the jacking structure triggers and activates the pressure reducing valve assembly, and an air outlet channel in the pressure reducing valve assembly is made to be communicated. The pressure reducing valve assembly and the output end cover are designed to be of a split structure, air path conduction is achieved through the jacking structure arranged in the output end cover, the strong sealing requirement does not exist in the process that the pressure reducing valve assembly and the output end cover are matched to trigger conduction, and a user does not need to conduct strong screwing for high-pressure sealing of a port; the problems that when a common user assembles the high-pressure gas cylinder and the pressure reducing valve, high-pressure sealing is needed, and leakage is prone to being caused by misoperation, sealing piece aging and the like can be effectively solved, terminal user operation is simplified, and using convenience and safety are improved.

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.
