Abstract
The utility model provides a short flow recovery system of air supporting tar ware separation light tar, including the light burnt oil pipe of groove in the middle of the tar and connection mechanized settling tank and air supporting tar ware, add a valve on light burnt oil pipe, connect an accumulator on the light burnt oil pipe between valve and the air supporting tar ware, the accumulator other end inserts in the middle of the tar groove top spare hole, other steam that connects cleans the branch pipe on the accumulator. The utility model can recycle the light tar separated by the air-float tar device, and directly improve the tar yield; the separation phenomenon of tar and ammonia water in the storage process of the crude tar is slowed down, and the tar loss caused by the water discharge operation after the crude tar is layered is avoided; the treatment load of subsequent equipment such as a mechanical clarifying tank, an air-float tar device and the like is reduced, and the blockage phenomena of an ammonia distillation tower plate, an ammonia distillation wastewater heat exchanger and an ammonia distillation wastewater pipeline are reduced.
Description
Technical field
The utility model belongs to coking chemical technical field, is specifically related to a kind of short route recovery system for air blast region air supporting tar device separation of lighter tar.
Background technology
Air blast region, gas purification working district, coking portion is provided with 4 air supporting tar devices, for removing tar light oil contained in remained ammonia, but isolated tar light oil returns again mechanical settling tank and again processes, both the processing load of mechanical settling tank had been increased the weight of, tar light oil too much turn increases mechanical settling tank tar and ammoniacal liquor fractional dose, is unfavorable for Tar production.If tar light oil enters ammonia still, ammonia still column plate, distilled ammonia wastewater interchanger and distilled ammonia wastewater pipeline can be blocked, the normal operation that serious restriction ammonia still process is produced.
Summary of the invention
The utility model aims to provide one can alleviate tar-processing system production load, reduces ammonia steaming system and ammonia spray system jams, improves the air supporting tar device separation of lighter tar short route recovery system of tar yield.
For this reason, the technical solution that the utility model is taked is:
A kind of air supporting tar device separation of lighter tar short route recovery system, comprise the tar light oil pipe of tar medial launder and connection mechanical settling tank and air supporting tar device, tar light oil pipe is set up a valve, tar light oil pipe between valve with air supporting tar device is connected a recovery tube, recovery tube the other end access hole for subsequent use, tar medial launder top, in recovery tube, side connects a steam soaking arm.
Described recovery tube diameter is 280 ~ 320mm.
The beneficial effects of the utility model are:
The tar light oil that 1, air supporting tar device can be separated is recycled, and directly improves tar yield.
2, tar light oil can slow down the coal-tar middle oil ammoniacal liquor separation phenomenon of crude tar oil storage process, and discharge water after avoiding crude tar oil layering the tar loss operating and cause.
3, the processing load of the follow-up equipment such as mechanical settling tank, air supporting tar device can be alleviated, reduce the latch up phenomenon of ammonia still column plate, distilled ammonia wastewater interchanger and distilled ammonia wastewater pipeline.
Accompanying drawing explanation
Fig. 1 is air supporting tar device separation of lighter tar short route recovery system structured flowchart.
In figure: mechanical settling tank 1, valve 2, air supporting tar device 3, tar light oil pipe 4, recovery tube 5, steam soaking arm 6, tar medial launder 7.
Embodiment
Can be by by Fig. 1, the utility model air supporting tar device separation of lighter tar short route recovery system, with on the basis of the tar light oil pipe 4 of air supporting tar device 3 at original mechanical settling tank 1, air supporting tar device 3, tar medial launder 7 and connection mechanical settling tank 1, tar light oil pipe 4 has been set up a valve 2, and valve 2 is in normally off.Tar light oil pipe 4 again between valve 2 with air supporting tar device 3 is connected the recovery tube 5 that a diameter is 300mm, above the hole for subsequent use, top of the other end access tar medial launder 7 of recovery tube 5.Meanwhile, also in recovery tube 5, side has connect a steam soaking arm 6, for daily pipeline cleaning and dredging.
Claims (2)
1. an air supporting tar device separation of lighter tar short route recovery system, comprise the tar light oil pipe of tar medial launder and connection mechanical settling tank and air supporting tar device, it is characterized in that, tar light oil pipe is set up a valve, tar light oil pipe between valve with air supporting tar device is connected a recovery tube, recovery tube the other end access hole for subsequent use, tar medial launder top, in recovery tube, side connects a steam soaking arm.
2. air supporting tar device separation of lighter tar short route recovery system according to claim 1, it is characterized in that, described recovery tube diameter is 280 ~ 320mm.
