Problems solved by technology

However, the carbon black industry is a typical source of air pollution. In the oil furnace carbon black production process, the carbon black tail gas discharged after the cyclone dust collector and bag filter is used to collect the carbon black in the flue gas has a high temperature (180-220 ° C), and it is also Contains carbon black particles and water, carbon monoxide, hydrogen, methane, oxygen, carbon dioxide, nitrogen and traces of hydrogen sulfide, sulfur dioxide, etc., with complex components
Carbon black particles and carbon monoxide, hydrogen and methane are all combustible gases, but the calorific value is low (2900~3500KJ Nm -3 ), and the carbon black particles remaining in the tail gas have a small particle size (20-80nm), high humidity (the relative humidity is greater than 38%), and are easy to scale, block, and corrode equipment on the equipment. Therefore, how to use this part High-temperature carbon black tail gas with a certain calorific value has always been a difficult point of concern for carbon black manufacturers

Abstract

The invention provides a green circular economy technology with coal coking as the main part. The technical scheme of the technology is as follows: a coal coking part, a coal tar processing part, a carbon black part and a part of combined power and thermoelectricity generation by coke oven gas are organically combined to form the relationship of industrial metabolism, symbiosis and coupling; suchmeasures as differentially utilizing tail gas of carbon black, recovering energy of coke drying quenching, reducing, recycling and changing the three wastes into resources, etc., enable resources to be saved, production cost to be reduced and pollution to be lessened; therefore, economic benefits of coal coking enterprises are maximized and the green circular economy technology is realized indeed. The invention also provides an apparatus for realizing the green circular economy technology with coal coking as the main part.

Description

technical field [0001] The present invention relates to a green circular economy process with coal coking as the main body, specifically a process for co-generation of heat and power with the coal coking process as the main body, cooperating with carbon black production, coal tar processing and coke oven gas power generation. Green" circular economy process. Background technique [0002] The theme of green circular economy is "reduction, reuse and resource utilization", which advocates the reduction of source input, the recycling and reuse in the production process, and the valuable recovery of terminal waste. The development of "circular economy" can maximize the effectiveness of resources, protect existing resources, prolong the utilization time of overall resources, reduce the input of resources, fully save and utilize energy, and reduce environmental pollution at the same time. has been focused. [0003] As an important basic energy and raw material for the country, co...
