The invention relates to a turmeric drink and a preparation method thereof. The preparation method comprises the following steps: (1) using an organic solvent to extract the turmeric extract in the fermented turmeric powder to obtain an extract containing the turmeric extract; (2) performing rectification on the extract to obtain the turmeric extract; (3) ) adding turmeric extract, kudzu root powder and syrup into boiling water, and stirring to obtain a gelatinized mixture; (4) cooling the gelatinized mixture, and adding honey and soybean lecithin under aseptic conditions to obtain a turmeric drink. The invention adopts fermented turmeric powder to extract curcumin, which improves the extraction rate. The present invention combines turmeric extract with kudzu root powder, syrup, honey and soybean lecithin powder, and combines a specific production process to solve the problems of low absorption rate of curcumin by the human body, insoluble in water and easy precipitation and stratification, and enhance The anti-alcoholic, liver-protecting, anti-oxidation and anti-mutation effects of turmeric drink have been discovered, and a new way for the utilization of turmeric has been expanded.

The invention relates to a solid powder multi-element composite infiltration agent and a composite infiltration process, and belongs to the technical field of metal surface treatment. The composite infiltration agent is composed of a chromium source, a vanadium source, a boron source, nickel powder, an activating agent, a filling agent, an oxygen scavenger and a rare-earth infiltration enhancer. The composite infiltration agent has the effects of rapid infiltration speed, no pollution, improving the structural density of an infiltration layer, and avoiding the embrittlement of the infiltrationlayer. The composite infiltration process comprises the following steps of carrying out acid pickling activation pretreatment on a base body material, then burying the base body material into the composite infiltration agent, heating and preserving heat in a carbon-containing or nitrogen-containing atmosphere, and then carrying out quenching treatment after furnace cooling. According to the process, the method is simple, no pollution occurs, the infiltration speed is rapid, the infiltration agent is free of hardening, and the surface of an infiltrated workpiece is clean. The prepared composite infiltration layer is fine in the crystalline grains and compact in the structure, has a good gradient structure, has the toughness, the wear resistance, the corrosion resistance, the high-temperature oxidation resistance and the like, and can be applied to parts such as a tool, a mold, a bearing, and a gear.

The invention relates to an in vivo degradable dispersion-strengthened biomedical multi-element magnesium alloy and a preparation method thereof. The weight percentage of its components is: Zn 1.9-2.1%, Ce 0.5-1.4%, Ca 0.9-1.0%, Mn 0.4-0.5%, and the rest is Mg; a finely dispersed second phase is distributed in the magnesium matrix. First, the alloy ingot is melted according to the designed composition, in which Ce promotes the discontinuous distribution of the second phase along the crystal, and then the second phase can be fully dissolved into the matrix phase after solid solution treatment, and then the aging will make the fine second phase in the magnesium matrix phase. Dispersed precipitation in the interior. The obtained magnesium alloy has the advantages of high strength and toughness, corrosion resistance, good biocompatibility, and complete degradation in vivo, and can be used for biological implants such as bone plates, bone nails, and intravascular stents. The invention can significantly improve the microstructural defects of magnesium alloys produced by traditional melting and casting methods. Through the aging precipitation strengthening effect of the fine second phase, while greatly improving its processing performance and mechanical properties, it can solve the excessively fast biological corrosion rate in its clinical application. question. Its process operation and equipment requirements are simple, and it has a good industrial application prospect.

The invention aims to provide a marine exhaust gas SOx removal device for a rotary spraying refluxing bubble tower. The marine exhaust gas SOx removal device comprises a washing tower, a NaOH solution storage cabin, a waste liquid buffer tank and waste liquid centrifugal treatment equipment; the washing tower comprises a washing tower outer layer cylinder; a washing tower inner layer cylinder and a spiral rising washing pipeline are arranged in the washing tower outer layer cylinder; an exhaust gas inlet, an exhaust gas outlet and a washing liquid outlet are respectively formed in the outer wall of the washing tower outer layer cylinder; the exhaust gas inlet is connected with a marine diesel engine exhaust pipe; the exhaust gas outlet is communicated with the atmosphere; the washing liquid outlet is communicated with the waste liquid buffer tank; the waste liquid buffer tank is connected with the waste liquid centrifugal treatment equipment; the waste liquid centrifugal treatment equipment is connected with each of an oil contamination storage cabin and a heavy residue storage cabin. According to the marine exhaust gas SOx removal device, SO2 in exhaust gas is subjected to washing treatment by adopting two technologies, namely a novel rotary spraying washing technology and a novel pneumatic stirring bubbling washing technology; the contact path between the washing liquid and the exhaust gas is increased; the acting time is prolonged; the acting area is increased, so that the exhaust gas is treated sufficiently.

The invention discloses a process for dehydrating hydrocarbon-based gas. The present invention proposes to use a dry stream which is rich in C4 to C10 hydrocarbons as stripping agent for improving theregeneration of the liquid desiccant according to the invention. This dry stream rich in C4 to C10 hydrocarbons is extracted from the gas derived from the dehydration, for example during a step of extraction of NGL located downstream of the gas dehydration unit. The stream of stripping agent recovered at the outlet of the liquid desiccant regeneration unit may be recycled into the process of theinvention or sent to a unit external to the process according to the invention. For example, this stream of stripping agent recovered at the outlet of the regeneration unit is sent to a unit which canreceive wet condensates, such as a three-phase separation unit at the inlet of a crude gas processing plant, a condensate stabilization unit, etc.
