Abstract
The utility model relates to a tank car dust-conveying device for dry dust removal of blast furnace gas, which comprises a large dust bin, a feeder, a dust-conveying gun, a hose, a quick joint, a tank car, a uniform pressure and fluidization pipe for nitrogen gas, and a detection system. The utility model is characterized in that the gas dust in the large dust bin uniformly baited, the dust is pumped and conveyed to the dust tank car through the dust-conveying gun, and the dust-conveying process sometimes needs nitrogen gas to equalize pressure of the dust bin and conveys dust through the nitrogen gas. The dust-conveying device is provided with a matched dust level meter and signals for empty material or full material of the tank car, the utility model changes the previous open conveying mode for humidification and dust discharge, and becomes a totally-enclosed dry dust conveying system. The utility model has the advantages of simple operation, total obturation without dust and gas leakage, fire resistance, explosion resistance, and assurance for safe production.
Description
Technical field
The utility model belongs in the Iron And Steel Industry coal gas ash e Foerderanlage in the blast furnace gas dry dusting technology, equally also is applicable to the discharging and the transportation of other dedusting dry ash.
Technical background
Blast furnace gas is since adopting dry method dust, and the discharging of coal gas dry ash is the problem that everybody pays close attention to carrying facility all the time.Because it has a lot of characteristics, just determined the diversity of processing unit.
Coal gas dry ash row, defeated main employing is that worm conveyor or buried scraper conveyor are joined chapelet at present, and ash is risen to high-order grey storehouse, and it is moistening by the spiral humidifier ash to be added water then, entrucks and carries away.
Also have plenty of cancellation high-order grey storehouse and bucket elevator, dry ash directly or concentrate and fall into the compartment after delivering to spiral humidifier humidification.
No matter be any configuration, all belong to open system, the coal gas ash directly falls into automobile.These configuration shortcomings are the spaces that all have airborne dust, have pollution.This external equipment is many, and failure rate is also high.
The utility model is to adopt the defeated ash of pneumatic conveying method fully.Use and air conveying ash is delivered to high-order grey storehouse, utilize pneumatic conveying method to pump to special-purpose grey tank car from the grey storehouse of a high position again.
Air conveying to the existing patent of high-order grey storehouse technology, the utility model is that the ash in high-order grey storehouse is with air conveying new device to grey tank car.
Summary of the invention
The purpose of this utility model is defective and the deficiency that overcomes prior art, provides a kind of configuration simple, easy to operate, reliable, totally-enclosed free of contamination blast furnace gas dry dusting tank car ash conveying device.
The utility model solves the technical scheme that this technical problem is taked: below the grey storehouse of a high position revolving plow reclaimer is installed, by pipe connecting, ash transportation gun, flexible pipe, link to each other with grey tank car, ash in the high-order grey storehouse is by the even blanking of revolving plow reclaimer, be drawn in the tank car through ash transportation gun, flexible pipe, nitrogen pressurising and nitrogen ash handing pipeline are installed on the grey storehouse of a high position.
Ash transportation gun is equipped with the ball valve of regulating flow, and the ash transportation gun inwall has wear-resistant liner.
The tapering in high-order grey storehouse is equipped with hopper wall vibrator.
The ash in high-order grey storehouse is through the even blanking of revolving plow reclaimer, and material pumps to bulk cement truck by ash transportation gun, flexible pipe negative pressure.All processes is airtight process, does not have any gas, dust leaks, and has kept the cleaning of production environment.
Because the ash of each casing of bag-type dust is imported high-order grey storehouse with high pressure gas or nitrogen, if adopting coal gas carries, the band ash enters big grey storehouse and also will purify recovery to coal gas, ash storehouse atmosphere generally is coal gas or nitrogen, do not wish to have air admission, so carry in big grey storehouse or pressurized gas nitrogen preferably when tank car is pumped defeated ash.
The part dry ash is met the characteristic of air spontaneous combustion in addition, and must not or fail ash this moment with the air ftercompction.All be connected with nitrogen tube in grey storehouse cone and ash transportation gun end for this reason.
Have only definite dry ash not have pyrophoricity and defeated ash does not adopt coal gas to transport just can to consider the air pressurising.But have, no pyrophoricity often changes with the furnace charge variety variations, so the mineral never spontaneous combustion strong pyrophoricity that may become suddenly of coal gas ash that changes is still safer with nitrogen pressurising and defeated ash.
Complete assembly also is provided with corresponding off-set facility as revolving plow reclaimer, hopper wall vibrator, pipeline, valve etc.Also be provided with high and low level gage in grey storehouse and tank car sky, full signal, so that grasp operation.Has wear-resistant liner in the ash transportation gun pipe in addition.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a device synoptic diagram of the present utility model.
1. high-order grey storehouse 2. revolving plow reclaimer 3. ash transportation guns, 4. flexible pipes and rapid-acting coupling 5. grey tank car 6. nitrogen tube 7. hopper wall vibrators 8. ball valves among the figure
Embodiment
Ash in Fig. 1 in the high-order grey storehouse 1,, is drawn into dry ash in the tank car by flexible pipe and rapid-acting coupling 4 through tank car 5 suction functions to ash transportation gun 3 through revolving plow reclaimer 2 even feedings.Pneumatic ash conveying is carried out to the logical nitrogen of ash transportation gun simultaneously by nitrogen pipeline 6 inflated with nitrogen ftercompctions in the defeated big grey storehouse of grey process.The ash transportation gun front end has ball valve 8, can carry out Flow-rate adjustment, and ash transportation gun inner liner abrasive resistant material is to improve work-ing life.For ash is smooth and easy down, high-order grey storehouse is provided with hopper wall vibrator 7.
Because the ash amount is usually very big in the grey storehouse, and the tank car capacity is less, so tank car is provided with the full signal of the empty material of material, when send signal near full load, high-order grey storehouse stops blanking.
