Coke oven and coking process method

Abstract

The invention relates to a coke oven and a coking process method. The coke oven comprises a drying and preheating chamber positioned at the upper part of the coke oven, a burning chamber and a carbonization chamber positioned at the lower part of the coke oven, and a heat exchange chamber positioned below the drying and preheating chamber and on the burning chamber and the carbonization chamber, wherein coal is dried and preheated in the drying and preheating chamber; gas air heats the carbonization chamber by heat generated during burning of the burning chamber, and the coal dried and preheated in the drying and preheating chamber enters the carbonization chamber for dry distillation to obtain coke and generate raw coke oven gas; and gas / air is preheated after the heat exchange with high-temperature gas in the heat exchange chamber. The coking process method is characterized in that coal is dried and preheated in the drying and preheating chamber; the coal dried and preheated in the drying and preheating chamber enters the carbonization chamber for dry distillation to obtain coke and generate raw coke oven gas; gas / air is preheated in the heat exchange chamber, then enters the burning chamber to be burnt and generate high-temperature gas, and the heat part is conveyed into the carbonization chamber for the dry distillation of the coal and then enters the heat exchange chamber for heat exchange with gas / air; and finally the heat enters the drying and preheating chamber for drying and preheating the coal.

Description

technical field [0001] The invention relates to the field of metallurgical coking, in particular to the transformation technology of coke oven structure and coking process. Background technique [0002] The main products of the coking industry - chemical products such as coke, gas and coal tar are important raw materials for metallurgy, machinery, chemical industry, city gas and other industries. China is the largest coke production, consumption and export country in the world today. The coking industry has become a major industry that plays a very important role in my country's national economy. [0003] The coke oven has experienced a history of more than 200 years from the initial honeycomb oven to today's large modern coke oven. The traditional regenerator coke oven consists of three chambers and two areas, namely carbonization chamber, combustion chamber, regenerator, chute area, furnace top area and base part. The uppermost part of the coke oven body is the furnace ...
