Lignite catalytic device and lignite treatment system and method thereof

Abstract

According to the lignite catalysis device and the lignite treatment system and method thereof, lignite stored in a temporary storage bin is conveyed into corresponding catalytic reaction kettles through a material distribution spiral device, and then the lignite gathered in the temporary storage bin is divided into multiple parts; the lignite and the lignite catalytic additive are mixed in each catalytic reaction kettle, the contact area of the lignite catalytic additive and the lignite is fully increased, the catalytic effect on the lignite is further improved, and the lignite catalytic additive and lignite particles are different in weight, so that the lignite catalytic additive is easily deposited at the bottom in the catalytic reaction kettle; the blades of the stirring mechanism are close to the inner side of the bottom wall of the catalytic reaction kettle in a reciprocating manner, so that the lignite at the bottom or the top of the catalytic reaction kettle is continuously turned over and is fully mixed with the lignite catalytic additive after being stirred in the vertical direction, the full contact between the lignite and the lignite catalytic additive is further improved, and the catalytic effect on the lignite is ensured.

Description

technical field [0001] The invention relates to the technical field of lignite treatment, in particular to a lignite catalytic device, a lignite treatment system and a treatment method thereof. Background technique [0002] Lignite is a type of coal with a large storage capacity. China's lignite reserves account for about 13% of coal reserves, and lignite in other countries in the world accounts for about 30% of coal mining. The total production and utilization of lignite is huge. At present, the utilization of lignite is a difficult problem in the world. The main problems are that lignite is flammable and difficult to store; lignite should reabsorb water after drying, which will greatly reduce the drying effect; low efficiency. Therefore, it is the most urgent problem to find an effective process to solve the problem of lignite utilization. At present, the main method is direct combustion of lignite to generate electricity, that is, lignite with a water content of about 4...
