Transverse alternate heating and vertical coke discharging type tamping coke furnace

Abstract

The invention discloses a transverse alternate heating and vertical coke discharging type tamping coke furnace, which comprises a coke furnace main body consisting of coking chambers and combustion chambers, a tamping coal charging vehicle on one side of the coke furnace main body and heat storage chambers on the other side of the coke furnace main body, wherein automatic furnace doors and coke treatment chambers are arranged at the bottoms of the coking chambers; the coke treatment chambers are provided with coke conveyors and dry quenching furnaces; and the combustion chambers are provided with a plurality of duplex horizontal flame paths which are connected with the corresponding heat storage chambers respectively. According to the tamping coke furnace, the lateral coal charging dust can be reduced; the overflow of flue gas and energy loss are avoided; the problems of environmental protection and energy conservation are radically solved; a furnace door on one side of the coke furnace, a smoke guide vehicle, a coke discharging machine, a coke barrier vehicle, a coke quenching vehicle and a ground dust removal device can be eliminated, so that the structure of a conventional coke furnace is simplified, quantitative heating can be realized, a gas circulation path is short, the system resistance is low, and heated gas is convenient to adjust and uniform in heating; complex long and short chutes in a chute area and equipment such as a waste gas disk and a switch can be eliminated, and the number of irregularly-shaped bricks can be reduced, so that investment in the coke furnace is greatly reduced, the running cost is reduced, production operation is simplified, the environment is protected, and energy is saved.

Description

technical field [0001] The invention relates to a horizontal alternate heating and vertical coke discharge type tamping coke oven, which belongs to the technical field of tamping coking in the coking industry of the metallurgical industry. Background technique [0002] Existing tamping coke ovens all adopt the technical process of vertical double fire channel heating, horizontal coal charging, and horizontal coke discharge. In the carbonization system, in order to ensure horizontal coal loading and coke discharge, there are auxiliary equipment such as furnace doors on both sides of the carbonization chamber, tamping and coal loading vehicles, coke pushing vehicles, coke blocking vehicles, coke quenching vehicles, etc. In order to clean production, save energy and protect the environment, and avoid coal charging and coke discharge smoke and dust emissions, a coal charging hole on the furnace top and a smoke guiding vehicle, a large-scale negative pressure dust removal device ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the horizontal coal charging and horizontal coke discharge process of the existing tamping coke oven carbonization system is unreasonable, there are many auxiliary machines, the coke oven machinery investment is huge, the production operation is complicated, coal charging, coke discharge pollution, and heat loss are serious; The upper, middle and lower distribution of the system is unreasonable, and the exhausted flue gas or heating gas is divided or merged horizontally / vertically or vertically / horizontally for many times, the structure is complex, the operation is difficult, and the system resistance is large
