Description
Technical field
The utility model is related to metallurgical coking fields.
Background technology
The transverse pipe initial cooler of the mating coke oven gas purification drum cooling system of Taiyuan Iron and Steel Co. coke-oven plant 7.63m coke ovens is in October, 2013
It goes into operation, starts the raised trend of resistance occur in January, 2016, up to more than 4000Pa causes gas-blowing engine suction not
Foot, causes coke-stove gas difficulty of transportation, and coke oven is caused to emit tobacco pollution environment, environmentally friendly accident occurs.Transverse pipe initial cooler is caused to hinder
Power is raised the reason is that 7.63m coke ovens are different from domestic positive pressure gas collecting tube coke oven from Germany's imported technology, and gas collecting tube is
Proven control negative pressure gas collecting tube, due to be negative pressure coke oven thus coal gas entrainment coal dust amount it is big, secondly at present coking coal enterprise be
It is even more to exacerbate coal dust amount in coal gas to improve the rate of recovery and cause more than 30% fineness of as-fired coal mud coal content greatly less than 0.5mm,
And coal dust mixes easily to be deposited in transverse tube coal gas primary cooler with tar in raw coke oven gas and resistance is caused to increase.And transverse pipe initial cooler is former
It is designed as rinsing using hot ammonium hydroxide online and reduces resistance, the shortcomings that such purging method is that ammonium hydroxide is difficult at the beginning of rinsing out transverse tube first
Secondly the tar and the conjugate of coal dust deposited between heat exchanger tube in cooler rinses hot ammonium hydroxide and is mixed into transverse pipe initial cooler flushing liquor, leads
The deterioration of flushing liquor quality, temperature raising are caused, the gas purification ability of transverse pipe initial cooler and heat transfer effect is caused to decline, after primary cooler
Gas temperature is exceeded up to 28 DEG C, and upper process coke oven environmental protection is influenced, and lower process coal gas and the recycling for changing product are also resulted in not
Profit influences.Therefore it is badly in need of optimizing existing transverse pipe initial cooler purging method solving the problems, such as that system resistance is high, keeps away
Exempt from coke oven and emit tobacco pollution environment.
Utility model content
Technical problem to be solved in the utility model is：The influence to flushing liquor quality how is eliminated, solves coal gas system
The problem of transverse tube resistance of uniting is high avoids coke oven from emitting tobacco pollution environment.
Technical solution is used by the utility model：A kind of transverse pipe initial cooler sprays liquid bath（6）Liquid outlet sequence it is logical
Cross the first water pump（3）, the first valve（2）Pipeline is connected to transverse pipe initial cooler（7）Import, transverse pipe initial cooler（7）Outlet it is suitable
Sequence passes through the second valve（4）, filter device（10）Pipeline is connected to sprinkling liquid bath（6）Liquid return hole, transverse pipe initial cooler（7）Go out
Mouth passes through third valve（5）Pipeline is connected to abacus（9）Liquid return hole, abacus（9）Liquid outlet sequence pass through the
Two water pumps（8）, the 4th valve（1）Connect transverse pipe initial cooler（7）Import.
The beneficial effects of the utility model are：The utility model develops a set of bypass flusher, using transporting offline
The transverse pipe initial cooler cut out is rinsed using flushing liquor method in capable rinse-system, effect designs the hot ammonia used than former
Water is obviously improved, and transverse pipe initial cooler resistance drops to 800Pa by 4000Pa, meets coke oven environmental requirement, has been prevented it and has been caused
Emit tobacco phenomenon.It is transformed by moving back liquid pipe to transverse pipe initial cooler flushing liquor, operation is isolated with flushing liquor for flushing liquor, sprayed
It spills liquid temperature to be decreased obviously, transverse pipe initial cooler temperature of exit gas has decreased to 22 ± 1 DEG C, and coal gas band water and impurity significantly subtract
Few, temperature reduces the recycling for improving benzene, daily more 0.5 ton of benzene of recycling, annual benefit 0.5*2500*364=54.6 ten thousand yuan.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in Figure 1, to prevent transverse pipe initial cooler flushing liquor from entering condensation liquid bath by moving back liquid pipe（Spray liquid bath）, so as to
Being mixed into flushing liquor influences its quality, moves back liquid pipe to transverse pipe initial cooler hypomere flushing liquor and is transformed, by flushing liquor and flushing liquor
Keep apart, it is 30m that flushing liquor, which enters newly-built volume,3Tar ship（Abacus）Middle storage recycles, flushing liquor independence shape
Into rinse-system, pollution of the flushing liquor to flushing liquor is avoided.After transformation, the primary cooler method of operation is changed to out by 3 standard-sized sheets
Two for one, and cutting out spare one, individually sprinkling is rinsed, and flushing liquor is not into existing sprinkling liquid bath, before the second valve of transverse tube bottom
Increase new liquid pipe of moving back, increase pipeline and individually lead to tar ship, with steam indirectly heat flushing liquor, control irrigating fluid temperature 75-
90 DEG C, then add flushing pump with new（Second water pump）Heat flush liquid pump is entered to cycle sprinkling in rinsed transverse pipe initial cooler to rinse about
10-15 days, for chemical examination flushing liquor containing naphthalene more than the flushing liquor that 20% postposition renews, old flushing liquor was discharged into the recycling of ammonium hydroxide separating tank.Change
Originally with 3 transverse tubes now only with 2 primary cooler gas treatments after making, technique adjustment is accordingly done, increases and enters 2 gas transverse pipes
Sprinkling flow quantity and pressure, ensure spray effect, hypomere sprinkling liquid pump is opened one for one, adjusted by fountain height maximum, ensured single
Platform fountain height is 150 ~ 160m3/h, pressure 0.45MPa.
