Process for simultaneously producing machine coke and molded coke by use of stamp-charging coke oven

Abstract

The invention discloses a process for simultaneously producing machine coke and molded coke by use of a stamp-charging coke oven. The process comprises the following steps: a, tamping the charged mixing molded coal in the vertical direction in a coal charging car by use of a tamping hammer, thereby obtaining a mixing molded coal cake of which the upper surface is of a slope surface shape; b, pushing the mixing molded coal cake of which the upper surface is of the slope surface shape into a coking chamber, forming the structure of a sloping hearth furnace by use of the mixing molded coal cake and the inner wall of the coking chamber, charging the molded coal into the coking chamber from the top of the coking chamber and stacking the molded coal on the mixing molded coal cake; and c, when the coke is mature, opening a coke side furnace door to one side so that the molded coal coke rolls out of the coking chamber under the action of gravity and by use of the gradient of the upper surface of the mixing molded coal cake coke, and after the molded coal coke rolls out completely, pushing out the bottom mixing molded coal cake coke by use of a coke pusher. The process is used for simultaneously producing the machine coke and the molded coke by use of the traditional stamp-charging coke oven without modification; as a result, the product types of a coking plant are increased and a new idea is provided for the modification of the traditional coking plant.

Description

technical field [0001] The invention relates to a molding coal tamping and molding coal coking process, in particular to a molding coal tamping and molding coal mixed filling tamping coke oven coking process. Background technique [0002] In the current relatively mature coke production process, the coke oven generally adopts a vertical inclined bottom furnace. Traditional top-charging coke ovens and rammed coke ovens are generally unable to be used to produce molded coke, because in traditional coke ovens, the placement of molded coal in the carbonization chamber has great disadvantages, and the molded coal is loaded into the carbonization chamber In this case, it is impossible to achieve uniform stacking, which will waste a long time in the coal charging process, and the furnace temperature will drop significantly, so the briquettes are piled up without order when entering the furnace. Like this, molded coal must have a large amount of contacts with carbonization inner wa...

AI Technical Summary

Problems solved by technology

[0004] Nowadays, the coke ovens used by most coking plants in China are tamping coke ovens or top-charging ovens, and the demand for molded coke is increasing, and the production capacity of domestic inclined-bottom furnaces cannot meet the requirements.
