Abstract

The invention discloses a method for recycling calcium carbide. The method comprises the following steps: dust removal step S1: crushing calcium carbide to obtain calcium carbide dust; collecting the calcium carbide dust through a first bag filter; conveying step S2: transport the calcium carbide dust to the calcium carbide dust storage bin; processing step S3: transport the calcium carbide dust in the calcium carbide dust storage bin into a briquetting machine to obtain calcium carbide granules; The processable calcium carbide dust is transported back to the calcium carbide dust storage bin; reaction step S4: transporting the calcium carbide granules into a calcium carbide generator to generate acetylene gas. The present invention realizes all recycling of calcium carbide dust through centralized closed recovery and reuse of calcium carbide dust, and uses it as raw material for polyvinyl chloride production after processing, which solves the potential safety hazard and raw material waste of calcium carbide dust generated in the process of calcium carbide crushing The problem.

Description

technical field [0001] The invention relates to the technical field of calcium carbide dust treatment, in particular to a method for recycling calcium carbide. Background technique [0002] Calcium carbide is the main chemical raw material for the production of polyvinyl chloride by the acetylene method. In the process of generating acetylene from calcium carbide, because the acetylene generator has requirements on the particle size of calcium carbide, the dry acetylene process generally requires the calcium carbide particle size to be 3mm (less than 1mm), and the wet acetylene process generally requires the calcium carbide particle size to be 30mm-50mm , and the calcium carbide produced is generally about 1000mm, so calcium carbide crushing is the primary process, and calcium carbide fine particles and calcium carbide dust will inevitably be produced during the crushing process of calcium carbide. On the one hand, calcium carbide dust reacts with moisture in the air to rel...
