Heat exchange chamber of coke oven and coke oven

Abstract

The invention discloses a heat exchange chamber of a coke oven. The heat exchange chamber of the coke oven comprises a chamber body, the interior of the chamber body is of a multi-layer structure, anair channel and a flue gas channel are arranged in each layer of the multi-layer structure in a penetrating mode, the layers of the multi-layer structure are sequentially communicated, the air channelis used for being communicated with the external environment, and the flue gas channel is used for being communicated with the external environment. And the flue gas channel is used for communicatingwith a vertical flame path of a combustion chamber in the coke oven. The invention also provides the coke oven adopting the heat exchange chamber. The heat exchange chamber is simple in structure, and the heat exchange efficiency of the coke oven can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of coking, and in particular relates to a heat exchange chamber and a coke oven including the heat exchange chamber. Background technique [0002] In the coking industry, when coking ovens are used for coking, the heat generated by raw coal gas and air combustion is usually used to heat the carbonization chamber to achieve carbonization of coal materials. [0003] Conventional regenerative coke ovens are currently equipped with a regenerator under the combustion chamber. The regenerator is used to preheat the combustion-supporting gas and raw coal gas at the same time, and then they are mixed in the combustion chamber for combustion. This regenerator The structure is complex, the heat exchange effect is poor, and the resistance to gas is large, the pressure drop is large, and gas leakage is prone to occur. At the same time, since the temperature of the combustion chamber can reach 1280°C-1400°C, the damage ...

AI Technical Summary

Problems solved by technology

For the bedroom coke oven, due to the large floor space and high investment cost of the horizontal coke oven, the width of the coal cake is 3-4m, the too wide carbonization chamber seriously affects the heat transfer effect, the coking time is too long, and, Direct heating is often used, and 1.5-4% of coal and coke will be burned to supplement the heat required for coal dry distillation, resulting in a reduction in production capacity; for vertical coke ovens, due to the existing vertical (heat recovery) coke oven When the volatile content of coal is low, the heat required for coal carbonization cannot be self-sufficient, and additional gas is required for supplementary combustion, which makes the heating efficiency low. Moreover, due to the different coking periods of different carbonization chambers, the amount of raw gas produced Different, resulting in uneven heating of the coke oven and long coking time
