Specific embodiment
With reference to the accompanying drawing and the utility model is described in detail in specific embodiment.
The utility model provides a kind of purification-recovery system for damaged tire cracking oil gas, as shown in Fig. 2, including splitting
Gas wash tower 1 is solved, cracks and is followed successively by light oil washing section and heavy oil washing section in gas wash tower 1 up and down, cracks the weight of gas wash tower 1
Oil wash section has been sequentially communicated heavy oil cycling element and heavy oil cooler 2 by pipeline, cracks the light oil washing section of gas wash tower 1
It is communicated with light oil cycling element by pipeline, the top of cracking gas wash tower 1 has been sequentially communicated purified gas aftercooler 3 by pipeline
With knockout drum 4.Wherein, heavy oil cycling element includes the weight for cracking the heavy oil washing pars infrasegmentalis of gas wash tower 1 and being sequentially communicated
Oil circulating pump 5 and heavy oil recirculation cooler 6, the other end of heavy oil recirculation cooler 6 pass through pipeline respectively and are connected to cracking air purge
Wash heavy oil washing section top and the heavy oil cooler 2 of tower 1.Light oil cycling element includes the light oil washing section for cracking gas wash tower 1
The other end of the light oil circulating pump 7 and light oil recirculation cooler 8 that lower part is sequentially communicated, light oil recirculation cooler 8 is connected by pipeline
Pass to the light oil washing section top of cracking gas wash tower 1.
When work, the cracking gas come from upper workshop section is sent into cracking 1 lower part of gas wash tower, cracking gas into after tower by efficient
