Process and system suitable for preparing ceramsite from high-calorific-value coal gangue
The invention discloses a process and system suitable for preparing ceramsite from high-calorific-value coal gangue, and the process comprises the following steps: 1, feeding a high-calorific-value coal gangue raw material into a granulation system, and granulating to obtain a coal gangue ceramsite raw material ball; 2, feeding the coal gangue ceramsite raw material pellets into a drying machine for drying, and controlling the water content after drying to be less than or equal to 2%; 3, feeding the dried coal gangue ceramsite raw material balls into belt type firing equipment, and removing volatile organic compounds and burning off the volatile organic compounds; 4, feeding the gangue raw material balls from which the volatile organic compounds are removed into a rotary short kiln for high-temperature calcination to obtain gangue ceramsite clinker balls; and 5, cooling the coal gangue ceramsite clinker balls through a grate cooler to obtain a coal gangue ceramsite product. The belt type firing equipment and the energy-saving rotary short kiln are connected in series, volatile organic compounds in the coal gangue are effectively volatilized and burnt out before entering the rotary short kiln, the total amount of the volatile organic compounds in the coal gangue ceramsite is reduced, and good social benefits and environmental benefits are achieved.
本发明公开了一种适应于高热值煤矸石制备陶粒的工艺及系统，包括如下步骤：一、将高热值煤矸石生料送入造粒系统进行造粒，得到煤矸石陶粒生料球；二、将煤矸石陶粒生料球送入烘干机进行烘干，控制烘干后的水分≤2％；三、将烘干后的煤矸石陶粒生料球送入带式烧成设备，进行脱除挥发性有机物并烧掉；四、将脱除挥发性有机物后的煤矸石生料球送入回转式短窑进行高温煅烧，得到煤矸石陶粒熟料球；五、将煤矸石陶粒熟料球经篦冷机冷却后，获得煤矸石陶粒产品。本发明将带式烧成设备和节能回转式短窑串联在一起，有效将煤矸石中挥发性有机物在进入回转式短窑之前挥发出来并烧掉，降低煤矸石陶粒中挥发性有机物总量，具有较好社会效益和环境效益。
