Abstract

The invention discloses a method for preparing active carbon by white spirit grains. The method comprises the following steps of pre-drying, drying, carbonizing, activating, recovery of pyrolysis products, cooling and refining. The increment of downstream products of the white spirit grains is greater than the investment input and the economic benefit is high, while the requirement on energy conservation and emission reduction can be met and the industry upgrading of the white spirit industry is improved, the method has great significance in developing the circular economy. The invention also discloses a device for preparing the active carbon by the white spirit grains. The device comprises an integrated furnace, an air current dry feeding system, a burning furnace and a gas-fired boiler, wherein the integrated furnace consists of a drying section, a carbonizing section, an activating section, a cooling section and an unloading section which are sequentially arranged from top to bottom; a heat exchange element of the drying section comprises a gas collecting angle boxes and gas discharging angle boxes which are alternately arranged abreast, so that hot smoke gas forms multiple strands of horizontal airflow in the drying section; materials which pass through the drying section are stressed laterally so as not to easily form a bridge; therefore, the integrated furnace can normally work while the white spirit grains are treated.

Description

technical field [0001] The invention relates to the field of organic solid waste recycling, in particular to a method and device for preparing activated carbon from distiller's grains. Background technique [0002] Liquor is a unique Chinese distilled wine made from grains and grains, using Daqu, Xiaoqu or bran koji, and distiller's yeast as saccharification starter, cooking, saccharifying, fermenting, and distilling. Distiller's grains are a by-product of brewing liquor. Most of the starch in the raw materials of liquor is used during the fermentation process, and protein, fat and a small amount of starch remain in the distiller's grains, which are theoretically useful. However, due to the addition of a large amount of Rice husks are used as fermentation fillers, and the process of separating and recovering protein, fat and starch in distiller's grains is difficult, and the benefits are lower than the costs. [0003] According to statistics, the annual output of distiller'...
