Formed coke clean production method and equipment

Abstract

The invention discloses a preparation method for formed coke and a piece of equipment, in particular to a method of using coke powder or anthracite, mill coal as primary material, adding powder normal temperature adhesive and coal tar powder, fully mixing, cold molding and performing, putting the coke adobe into a tunnel carbonization stove, giving a low temperature oxidation treatment to the coke adobe, to produce formed coke with a high quality. The forming equipment is over 24 times more efficient than the existing equipment by using multicavity composite mold and automatic feeding-ejection apparatus; the material needs no processing of drying and heat plasticizing; the elementary composition of the body can be adjusted freely; the formed coke has low sulfur content, low ash content, high fixed carbon content, no smoke in the combustion, high iron-coke ratio and good watertightness in the long time preservation. The investment scale with the same production capacity is only one twentieth of the heat seal - carbonization method; the working procedures of material drying, heat kneading, high temperature carbonization are saved, not only the production control becomes easy, but also the production process is more energy-saving; the tunnel type oxidation (or carbonization) stove realizes a continuous operation, has a large yield, and improves the productivity.

Description

technical field [0001] The invention relates to a short-flow production method and equipment for casting mold coke, in particular to a clean mold coke production method and equipment. Background technique [0002] At present, the existing production methods for producing molded coke usually adopt "heat-bonding-carbonization method" and cold-setting method, which have many production steps, long process flow, high investment scale of production line, low output, high ash content and difficult technical control, etc. However, the "heat-bonding-carbonization method" has disadvantages such as high production energy consumption and raw materials need to be dried; while the "cold-setting method" has high ash content, low fixed carbon content, smoke and low strength, fear of water, and raw materials need to be processed. Drying treatment does not have the disadvantages of large-scale professional carbonization equipment. Contents of the invention [0003] The object of the prese...
