Problems solved by technology

[0003] Domestic coking plants such as Benxi Iron and Steel Co., Ltd. and Handan Iron and Steel Co., Ltd. have developed the process of producing briquettes by using coking waste slag, but the waste slag is put into the mixing tank and mixed manually, and the formed briquettes are transported to the belt of the coke oven coal tower for distribution The production process is simple, the equipment is simple, and the manual operation is intensive, which can achieve the purpose of waste disposal, but the degree of mechanization is not high, which will easily affect the production and the health of the operators.
[0004] Chinese patent 200310114624.8 provides a new method and e

Embodiment Construction

[0023] The present invention relates to a method for producing coking briquettes by using coking organic waste and weakly caking coal as raw materials. The implementation steps include: (1) first mixing and pretreating the coking organic waste collected from the coking plant; 2) pretreating the weakly caking coal used for coking; (3) quantitatively and uniformly mixing the pretreated coking organic waste and weakly caking coal; (4) molding the uniformly mixed materials to produce (5) Mix the molded coal with coking coal according to a certain ratio and enter the coke oven for coking. After pretreatment of weakly caking coal and coking organic waste, all weakly caking coal and coking organic waste are mixed to make briquettes, and the briquettes are mixed with ordinary coking coal blending and then enter the coke oven for coking. The coking organic waste mainly includes any organic waste such as tar residue, acid tar, biochemical sludge and coal tar pitch produced in a coking p...

Abstract

The invention provides the method for producing molded coal with coking organic waste and baking coal. The method uses coking organic waste as binding agent, and then it is mixed with baking coal. The molded coal can be used as coking material. The method comprises baking coal breaker, coal dashpot, coking organic waste stirring device, coking organic waste dashpot, preliminary hybrid arrangement, homogeneous hybrid arrangement, and forming machine. The invention has the advantages of intimate mixing, high forming, solving environmental pollution, improving coke quality, save cost.

Description

Technical field [0001] The invention belongs to the field of coking organic solid waste pollution control and coking briquette processing, and in particular relates to a method and an equipment system for producing coking briquette by using coking organic waste and weak caking coal as raw materials. Background technique [0002] The coking plant produces organic solid waste, which accounts for about 0.1%-0.2% of the coke output of the coking plant, including tar residue, acid tar and biochemical sludge. Among them, the output of tar residue accounts for about 0.07%-0.1% of the coke output of the coking plant, and the output of acid tar accounts for about 0.05%-0.08% of the coke output of the coking plant, and its composition is mostly toxic and harmful organic matter. These coking organic wastes are likely to cause serious environmental pollution due to various reasons. How to realize their resource utilization and harmless treatment is a serious problem. On the other hand,...
