Regular visit is carried out to equipment simultaneously, the regular visit report of equipment is recorded, and for plan repair to crude benzol
Yield impact result and make report
2) different types of coal are made to carry out de- benzene using the prior art, so that the crude benzol generated to different types of coal detects,
Understand influence of the different types of coal to crude benzol yield, and the data influenced on different types of coal on crude benzol yield count, and
And the reason of different types of coal influence crude benzol yield is found out, to adjust Coal Blending Schemes in the case where guaranteeing coke quality, so
Coal Blending Schemes are implemented afterwards
3) during Coal Blending Schemes are implemented, it is ensured that whole cooler sprays tar light oil, and fills into crude benzol and newly wash
It is stringent when oily to be carried out according to standard operation, and picture monitoring is carried out per hour to circulating washing oil temperature and flow, and will
The circulating washing oil temperature that monitors every time and traffic income to data concluded and arranged
4) and increase a filter press, it will be in vacuum pump when carrying out de- benzene operation to increase the flow of big mother liquor pump
Vacuum stablize in -55~60kpa, and technical staff is allowed to debug by gas chromatograph, until debugging equipment tune
It tries successfully, so that the yield to crude benzol is promoted.
(3) beneficial effect
Compared with prior art, the present invention provides crude benzol recovery rate method for improving, have it is following the utility model has the advantages that
The crude benzol recovery rate method for improving is overhauled by paying close attention to all kinds of big property, reinforces equipment routing inspection, for planned
Maintenance and the crude benzol yield influenced can provide report, can the influence of effective solution coke oven fettling discharge of the coke, the large-scale of crude benzol is overhauled, greatly
The problem of unplanned property of type equipment is overhauled, and crude benzol yield can be directly or indirectly influenced carries out inspection to equipment, can be effective
Avoid equipment from situation occur, lead to the variation of crude benzol recovery rate, while after being overhauled to equipment, the variation inside equipment can pair
Crude benzol recovery rate impacts, and by making different types of coal carry out de- benzene using the prior art, understands coal to crude benzol yield
It influences, adjusts Coal Blending Schemes in the case where guaranteeing coke quality, the quality difference between coal, the adjustment of Coal Blending Schemes can be solved
Influence gas volume influences crude benzol yield indirectly, and by adhering to that whole cooler tar light oil sprays, new washing oil fills into the specification of system etc.
Operation sends out picture per hour and monitors circulating washing oil temperature and flow etc., can solve to wash benzene column absorption temperature height, it is straight to wash benzene low efficiency
The problem of influencing crude benzol yield is connect, by stable benzene -55~60kpa of vacuum, tracking Ji steel technical staff closely carries gas phase
Chromatograph is marched into the arena and is debugged, and improving produces plant process level of security and running quality, to promote tar yield, sulphur cream produces
Rate and ammonium sulfate yield, to promote the condition that crude benzol yield provides.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical solution in the embodiment of the present invention is clearly and completely retouched
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Crude benzol recovery rate method for improving, comprising the following steps:
