Embodiment Construction

[0020] The components of the sulfur-fixing agent are: 55 kg of calcium carbide slag, 15 kg of undersieve after crushing waste dry batteries, 15 kg of sulfur slag, and 15 kg of aluminum ash.

[0021] The steps of the specific preparation method are as follows:

[0022] (1) Carbide slag and sulfur slag are crushed through a 100-mesh sieve, and then mixed evenly with aluminum ash (crushed through a 100-mesh sieve) and waste dry batteries crushed (passed through a 100-mesh sieve) to obtain a sulfur-fixing agent.

[0023] (2) 77.5 kg of raw coal is pulverized.

[0024] (3) Add 2.5 kg of the sulfur-fixing agent prepared above to 77.5 kg of raw coal and mix well.

[0025] (4) Add 10 kg of clay and 10 kg of papermaking waste liquid to the mixture of raw coal and sulfur-fixing agent described in (3), and stir evenly with a mixer.

[0026] (5) Extrude with briquette machinery and equipment, and dry to obtain the finished product.

Abstract

The invention discloses a method for producing a sulfur-fixing agent and sulfur-fixing briquette prepared from the sulfur-fixing agent based on a waste dry battery as a raw material. The sulfur-fixing agent is composed of the waste battery, carbide slag, sulfur ore slag, aluminum ash and other industrial wastes. The finished product is obtained by uniformly mixing the sulfur-fixing agent with coal and adhesive, subjecting the mixture to mechanical extrusion forming and finally drying. The product has the advantages of high desulfurization efficiency, wide source of raw materials, low cost of the produced finished product and environmental protection.

Description

technical field [0001] The invention relates to a method for producing a sulfur-fixing agent by using waste dry batteries and a method for preparing sulfur-fixing briquettes, in particular to a method for producing a high-efficiency sulfur-fixing agent by using industrial waste and a method for preparing sulfur-fixing briquettes. technical background [0002] In the production of coal briquettes, in order to reduce the emission of sulfur dioxide, it is necessary to add a sulfur fixer to the coal, which can not only reduce environmental pollution but also fully utilize the resources of high-sulfur coal. [0003] The production method of the sulfur-fixing briquette is to crush the raw coal, mix it with a binder and a sulfur-fixing agent, extrude it with mechanical equipment, and dry it to obtain a finished industrial sulfur-fixing briquette with a certain strength and shape. [0004] Commonly used sulfur fixatives include calcium metal oxides, metal hydroxides and their salts ...
