Problems solved by technology

[0005] In the current coking production process, for the NOx and SO generated during coke oven heating 2 The coke oven flue gas can be purified by setting up a desulfurization and denitrification system, but the construction and operation of the desulfurization and denitrification system requires coking production enterprises to continuously invest more costs and energy
And for CO in coke oven exhaust gas 2 So far, there are no effective measures to reduce emissions

Embodiment Construction

[0031] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0032] Such as figure 1 , figure 2 As shown, a kind of internal heating type clean coking process of the present invention comprises the following steps:

[0033] 1) In the coke oven heating system 1, pure oxygen is used as the combustion-supporting gas to participate in the heating process of the coke oven; 4 , CO and other hydrocarbon coke oven gas as fuel, in the combustion unit 13 of the coke oven heating system 1, oxygen and coke oven gas are fully combusted, and the generated high-temperature flue gas enters the subsequent high-temperature coal carbonization system 2;

[0034] 2) In the coal high-temperature carbonization system 2, the high-temperature flue gas transfers heat to the coal and generates high-temperature flue gas. The main component of the high-temperature flue gas is CO 2 、H 2 O and a small amount of SO 2 , where CO 2 and...

Abstract

The invention relates to an internal-heating type clean coking process and system. The internal-heating type clean coking system comprises, connected in sequence, a coke oven heating system, a high-temperature retorting system for coal, a coal gas collection and purification system and a system for extracting hydrogen from coal gas. The process and system in the invention can effectively reduce orprevent the generation of atmospheric pollutants including CO2 during coking production, produce clean energy products, improve the utilization efficiency of resources and energy in coking, lower theemission of atmospheric pollutants and greenhouse gas produced in coking, and create a green ecological project in the coking industry.

Description

technical field [0001] The invention relates to the technical field of coal coking, in particular to an internal heating clean coking process and system. Background technique [0002] Coking is the process of converting coal suitable for coking into coke and gas through high-temperature dry distillation. At present, the most widely used coking equipment in the field of coal coking is the mechanized regenerative coke oven, which adopts the form that the carbonization chamber and the combustion chamber are arranged adjacent to each other. In the combustion chamber, the gas used to heat the coke oven (coke oven gas or other types of gas) is mixed with air and undergoes a combustion reaction, releasing a large amount of heat at the same time. The heat generated by combustion is transferred to the coal material in the carbonization chamber through the furnace wall between the combustion chamber and the carbonization chamber. Raw coal gas is formed under the action of high tempe...
