Method and system of producing molded coal by coking organic castoff and weakly caking coal

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,...

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 equipment system for producing coking briquettes. This method also uses waste slag from coking plants as a binder to mix coking coal with coking coal. Coking waste slag is only mixed once, so it is very easy to cause uneven mixing of waste slag and coal, affecting the quality of briquette coal, and then affecting the quality of coke; in addition, the patent does not mention the use of weakly caking coal as raw material for processing briquette coal, and has not achieved reduction Target of coking cost

In this patent method, the use of light oil as the binder increases the cost, and the binder needs to be pretreated at 200°C-220°C, which is prone to environmental pollution
