Heat storage device for transversely heating vertical coke exhaust coke oven

Abstract

The invention discloses a heat storage device for transversely heating a vertical coke exhaust coke oven. The heat storage device is distributed at two sides or one side of the coke oven, and comprises a plurality of regenerative chambers arranged in parallel, wherein the internal part of each regenerative chamber is partitioned into a plurality of heat exchange channels up and down; the heat exchange channels are correspondingly connected with a horizontal flame path of a combustion chamber; each heat exchange channel comprises a lean gas/flue gas heat exchange branch channel and an air/flue gas heat exchange branch channel, which are horizontally arranged; and a heat accumulator is arranged inside each heat exchange channel. The heat storage device disclosed by the invention is transversely connected with the combustion chamber, the heat storage device is divided into a plurality of transversely independent heat exchange chambers up and down, and transverse intermittent heat exchange on the heating gas and the discharged flue gas is carried out in the heat exchange chamber, so that the up and down complicated structural relationship of the regenerative chambers of the existing coke oven is simplified, and long and short chutes of a chute area are concealed, the quality of shaped bricks is reduced, a gas flow path is short, small in resistance and convenient to adjust, and quantitative and uniform heating can be achieved. Therefore, investment is reduced, and a production operation is simplified.

Description

technical field [0001] The invention relates to a heat storage device for horizontal reciprocating or alternate heating of a vertical coke discharge type coke oven, which belongs to the technical field of coking in the coking industry of the metallurgical industry. Background technique [0002] The heating system of the existing coke oven is distributed in the upper, middle and lower areas of the coke oven. On the upper part of the furnace body, dozens of carbonization chambers and dozens of combustion chambers are distributed alternately. Each combustion chamber is composed of more than 30 vertical Composed of fire paths, every two vertical fire paths form a pair of double-connected fire paths, one of which goes through the rising combustion airflow, and the other goes through the descending flue gas, and the cycles are alternated. In the middle of the furnace body, there are also dozens of regenerators, which are equipped with regenerators. The regenerators absorb the wast...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that the upper, middle and lower distribution of the existing coke oven heating system is unreasonable. The central heat storage area and the lower heating gas and flue gas entry and exit areas occupy the lower area of ​​the vertical row coke oven for gravity coke discharge. The horizontal coke discharge has to rely on auxiliary coke oven machinery, which has environmental pollution problems; the top of the regenerator is connected to the combustion chamber through long and short ramps, and the flow of heating gas in the vertical flue is adjusted by adjusting bricks. The bottom of the chamber is connected with the horizontal small flue through the grate bricks, and the heating gas and the external flue gas are adjusted through the grate bricks to change the horizontal / vertical or vertical / horizontal direction of the airflow and the diversion or confluence of the airflow. The structure of the furnace body is complex, and the airflow Difficult adjustment operation, high system resistance, high infrastructure investment
