Problems solved by technology
[0002] In the wet vacuum distillation process, there are problems of water recycling and sewage. Generally, water recycling is not considered, and sewage and water pollutants are treated in a centralized manner; this kind of centralized treatment of various sewage and sewage substances has a high degree of intensification. High efficiency, high utilization rate of equipment, but high facility cost, difficult to classify pollutants

The invention discloses an oil-water separation circulating system for processing polycyclic aromatic hydrocarbon oil by adopting a wet vacuum distillation process. The system comprises a sewage feeding tube, wherein the oil-water separation circulating system also comprises a first stage of oil separation tank and a second stage of oil separation tank; a first stage of water distribution chamber and a first stage of oil distribution chamber are arranged on the first stage of oil separation tank; a second stage of water distribution chamber and a second stage of oil distribution chamber are arranged in the second stage of oil separation tank; the sewage feeding tube is connected with the first stage of water distribution chamber; the first stage of water distribution chamber is connected with the second stage of water distribution chamber through a pipeline; the first stage of oil distribution chamber and the second stage of oil distribution chamber are connected with an oil outlet pipeline; the second stage of water distribution chamber is connected with a water circulating system through the pipeline. The water processed by the oil-water separation circulating system completely can achieve the steam water requirements, the wastewater throughput is reduced to the maximal extent, and meanwhile, the separated oil enters a raw material system, so that the yield of the product is effectively improved.
Description
technical field [0001] The invention relates to the technical field of heavy oil treatment in petrochemical industry, in particular to an oil-water separation and circulation system for processing condensed-ring aromatic hydrocarbon oil by a wet vacuum distillation process. Background technique [0002] In the wet vacuum distillation process, there are problems of water recycling and sewage. Generally, water recycling is not considered, and sewage and water pollutants are treated in a centralized manner; the centralized treatment of such various sewage and sewage is highly intensive. High efficiency and high equipment utilization, but high facility cost and difficult pollutant treatment and classification. SUMMARY OF THE INVENTION [0003] The object of the present invention is to overcome the shortcomings and prejudices of the above-mentioned prior art, and provide an oil-water separation and circulation system for processing fused-ring aromatic hydrocarbon oil by a wet v...
