The invention relates to the field of a Maotai-flavor liquor brewing process, in particular to a Maotai-flavor liquor stacking saccharification method which can reduce the weight of heap core fermented grains, further increase the air contact surface of the bottom area of a saccharification heap, further enable the saccharification heap to be in better contact with air and improve the saccharification effect. Comprising the following steps: a, conveying fermented grains to a stacking fermentation process after the fermented grains are subjected to a cooking and gelatinizing process, a steaming and steaming process, a spreading and airing process and a koji adding process; b, during stacking, the temperature of the saccharification pile is in a range of 23-32 DEG C; c, when the accumulation is completed, the accumulation temperature of the saccharification pile is in a range of 28-55 DEG C; and d, then, after the fermented grains are spread and dried and the yeast is added, conveying the fermented grains from the spreading and drying machine into a saccharifying hopper of a stacking saccharifying device, and then transferring the fermented grains to a three-dimensional support frame of the stacking saccharifying device. The method is especially suitable for the accumulation saccharification process of Maotai-flavor liquor.

This invention discloses a leather processing waste gas adsorption and purification device, belonging to the field of industrial waste gas treatment technology. The device includes a purification chamber, an exhaust fan, an inlet pipe, an outlet pipe, a clamping assembly, an activated carbon group, a receiving cavity, an outlet branch pipe, an inlet branch pipe, and an exhaust branch pipe. Because the diameter of the outlet pipe is smaller than that of the inlet pipe, the waste gas entering through the inlet pipe cannot be completely discharged through the outlet pipe. As a result, the air enters the interior of the outlet branch pipe through the receiving cavity, then enters the interior of the inlet branch pipe and contacts the activated carbon group again for purification and adsorption. Subsequently, it enters the interior of the outlet pipe through the exhaust branch pipe and is discharged outward. The waste gas discharged directly through the outlet pipe can undergo two adsorptions and purifications by the activated carbon groups on both sides, thereby increasing the residence time of the waste gas. Furthermore, waste gases from different paths can undergo two adsorptions and purifications by the activated carbon groups, resulting in better adsorption and purification effects.

The invention relates to the technical field of coal mine return airways, in particular to a coal mine return airway spraying curtain control device which comprises a base plate, two sliding plates are mounted on one side of the base plate, sliding assemblies sleeve the two sliding plates, a water inlet groove is formed in the bottom of the base plate, and a water blocking assembly is arranged at the top of one end of the water inlet groove. A rotating assembly is arranged in the middle of one side of the base plate, a water diversion assembly is arranged at the top of the base plate, connecting assemblies are arranged on the sides, away from each other, of the base plate and the sliding assembly correspondingly, and supporting assemblies are arranged at one ends of the connecting assemblies and one end of the base plate correspondingly. When people go in and out, the side rod is pushed to drive the movable fence to move rightwards, and people can go in and out conveniently.
