Problems solved by technology
This part of the solid semi-coke is not converted and utilized in the process of coal-to-acetylene, and is directly quenched and discharged from the reactor. Not only is the energy conversion efficiency low, but the high-temperature sensible heat brought out is not utilized in the process through the quenching process, and the energy utilization rate of the system is greatly improved. reduce

Description
technical field [0001] The invention relates to the technical field of acetylene production, in particular to a reactor for thermal plasma cracking coal to produce acetylene. Background technique [0002] In related technologies, the research on thermal plasma cracking coal to acetylene process mainly starts from the perspective of acetylene yield. Acetylene yield and specific energy consumption are important indicators to measure the feasibility of thermal plasma cracking to acetylene, and the reactor structure is It has a significant impact on the yield of acetylene and specific energy consumption. Looking at all plasma coal-to-acetylene reactors, in the process of thermal plasma cracking coal to acetylene, only the volatile matter in the cracked coal is converted into acetylene gas, the yield of acetylene is only 20%-40%, and the conversion rate of raw coal is low, accounting for 50%. More than 100% of the solid semi-coke does not participate in the reaction, and is disc...
