Coke oven capable of horizontally heating continuously and vertically extracting coke

Abstract

A coke oven capable of horizontally heating continuously and vertically extracting coke comprises coking chambers, combustion chambers, and heat exchange chambers arranged on the two sides of each of the combustion chambers, wherein an automatic oven door is arranged at the bottom of the coking chamber, a coke processing chamber internally provided with a conveyor is arranged below the coking chamber and the combustion chamber, a dry quenching furnace is arranged at the tail end of the conveyor, the combustion chamber is divided into a left cavity and a right cavity, each cavity is vertically divided into even number of horizontal flame paths, airflow holes are left close to a central partition between the first layer of the flame path and the second layer of the flame path, airflow holes are left close to an external wall between the second layer of the flame path and the third layer of the flame path, and so on; a smoke outlet is arranged at the outer end of the highest layer of the flame path, a main combustor is arranged at the outer end of the lowest layer of the flame path, and the heat exchange chambers are arranged on the two sides of each of the combustion chambers respectively to be connected with the main combustor and the smoke outlet. The coke oven automatically extract, convey and quench the coke in a closed environment and utilizes the nitrogen gas to cool in a circulating manner and remove dust, therefore, the problems of environmental protection and energy saving are solved fundamentally, meanwhile, the structure of an oven body is greatly simplified, a large-scale auxiliary coke oven machinery is cancelled, and then the cost of the coke oven is lowered, and the operation cost is saved.

Description

technical field [0001] The invention relates to a horizontal continuous heating and vertical coking discharge type coke oven, which belongs to the conventional coking technical field in the coking industry of the metallurgical industry. Background technique [0002] Existing large-scale conventional mechanical coke ovens are all composed of a coal material carbonization system and a gas heating system. In the upper part of the furnace body, dozens of carbonization chambers and dozens of combustion chambers are distributed alternately. In the combustion chamber, the heating gas is burned, and the heat is transferred to the carbonization chamber through the furnace wall. In the carbonization chamber, the coal material is heated and carbonized; in the furnace body In the middle part, there are dozens of heat exchange chambers, which are used to continuously recover the waste heat of the flue gas and preheat the heating gas; Flue, branch flue, exhaust gas tray, etc., are used t...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a horizontal continuous heating, vertical coke discharge type coke oven, which is used to change the existing coke oven vertical heating intermittent heating operation and its complex furnace structure, and change the unreasonable horizontal coke discharge. Process flow, reduce supporting coke oven auxiliary machinery, avoid pollution and high energy consumption in the open environment, simplify production operations, and reduce investment
