Preparation device and preparation method for preparing desulfurizer through deep purification treatment of carbide slag

Abstract

The invention discloses a preparation device and a preparation method for preparing a desulfurizer by deep purification treatment of carbide slag, belongs to the technical field of desulfurizers, and aims to solve the problem that the prepared desulfurizer is poor in quality due to insufficient reaction and dissolution of lime, water and a water solvent after standing. A feeding hopper is fixedly installed on one side of the preparation box, a material box is arranged in the preparation box, a preparation barrel is fixedly installed in the preparation box, a feeding pipe is fixedly installed on the other side of the preparation box, one end of the feeding pipe penetrates through the preparation barrel and is fixedly connected with the preparation barrel, and a discharging pipe is fixedly installed at the bottom end of the preparation barrel. The discharging pipe penetrates through the preparation box and is fixedly connected with the preparation box; the stirring rod is driven to rotate, the stirring rod enables the stirring fan blades to rotate through the connecting sleeve, and the stirring fan blades stir lime, water and a water solvent in the preparation barrel, so that preparation of the desulfurizing agent is conveniently completed, and the quality of the prepared desulfurizing agent is effectively improved.

Description

technical field [0001] The invention relates to the technical field of desulfurizing agents, in particular to a preparation device and method for preparing desulfurizing agents through advanced purification treatment of carbide slag. Background technique [0002] Calcium carbide slag: the waste residue mainly composed of calcium hydroxide after the hydrolysis of calcium carbide to obtain acetylene gas. Acetylene (C2H2) is one of the important raw materials in the basic organic synthesis industry. The process of producing acetylene with calcium carbide (CaC2) as raw material and adding water (wet method) is simple and mature, and currently accounts for a large proportion in my country. Adding water to 1 ton of calcium carbide can generate more than 300 kg of acetylene gas, and at the same time generate 10 tons of industrial waste liquid with a solid content of about 12%, commonly known as calcium carbide slurry. The use of calcium carbide slag can replace limestone to make c...

Problems solved by technology

[0003] 1. At present, when preparing desulfurizers for purifying calcium carbide slag, most of the lumpy limes are directly placed in water and water solvents, and after standing still, the lumpy limes react with water and water solvents and dissolve. The amount of desulfurizer used to purify calcium carbide slag is relatively large, and this method makes the preparation efficiency of desulfurizer relatively low;

[0004] 2. Due to the insufficient reaction and dissolution of lime, water and water solvent after standing still, the quality of the prepared desulfurizer is poor. Therefore, we propose a kind of calcium carbide slag deep purification treatment to prepare desulfurizer The preparation device and preparation method are used to solve the above problems
