The application discloses a liquor tailing acid substance extraction method in liquor brewing and liquor, and comprises the following steps of pretreatment, selective adsorption, gradient desorption, membrane separation and purification and liquor body blending. The chelation precipitation-microfiltration coupling process is adopted in the pretreatment to remove metal ions and colloidal impurities; the acid substances are specifically adsorbed through a hexanoic acid molecular imprinting polymer adsorbent, and step-by-step elution is realized by combining with gradient pH desorption; high-purity acid concentrated solution is obtained through nanofiltration membrane separation and activated carbon adsorption, and after screening, the high-purity acid concentrated solution is blended with a base liquor body to improve the quality of the liquor.

The utility model discloses a kind of burner structures of high-purity magnesia sintering kiln, it is related to kiln technical field, including mounting ring, the outside of mounting ring is fixedly connected with mounting frame in annular arrangement mode, the side fixedly connected with burner body of mounting frame, the output end of burner body is movably penetrated in the inside of mounting frame.The utility model heats heating groove by burner body, removes residual moisture, carbonate in high-purity magnesia, while electric push rod drives mounting ring and burner body to carry out height reciprocating adjustment, so that heating groove is evenly heated, avoid local overheating or heating insufficient condition, to reduce the cracking, pulverization etc. Loss that high-purity magnesia is generated due to uneven heating, improve raw material utilization rate, simultaneously, uniform high-temperature environment can ensure that residual moisture and carbonate are completely decomposed, avoid impurity residue influence product purity.
