Description
Technical field
The present invention relates to a kind of mechanization tar ammonia dreg scraping trough, belong to Coking and Gas equipment technical field.
Background technology
From 80 °C of raw coke oven gas of coke oven, with tar and ammoniacal liquor along suction gas piping to gas-liquid separator, after gas-liquid separation
Raw coke oven gas is drawn by top, and coal gas is cooled into 21 °C into transverse pipe initial cooler.The coal gas discharged by transverse pipe initial cooler bottom, enters
Enter electrical tar precipitator, remove the tar carried secretly in coal gas, then sulphur ammonium unit is delivered to by gas-blowing engine.
The tar ammonia mixed liquor that gas-liquid separator is separated enters mechanization tar ammonia dreg scraping trough, utilizes mechanization tar
Ammoniacal liquor dreg scraping trough continuously scrapes tar slag therein to tar slag case, and coal blending facility is periodically sent to fork truck, is blended into coking coal.
The tar ammonia come out from mechanization tar ammonia dreg scraping trough enters tar ammonia water separator, using difference in specific gravity, carry out ammoniacal liquor and
The separation of tar.The ammoniacal liquor that tar ammonia water separator top is separated flows into bottom cyclic ammonia water medial launder, then by cyclic ammonia water pump
Extract out, be sent to coke oven collecting main sprinkling cooling coal gas；Tar in upper taper groove, tar medial launder is flowed into through overflow bottle, by
Tar pumped, delivers to oil depot unit.From cyclic ammonia water medial launder top, gravity flow enters remained ammonia groove to remained ammonia, by residue
Ammoniacal liquor pumped is sent to ammonia still process unit after filter, jet air float tar remover remove tar removing.
Mechanization tar ammonia dreg scraping trough is coke-oven plant's separating tar, ammoniacal liquor, the key equipment of tar slag.Equipment runs shape
The quality of condition, the separation to tar, ammoniacal liquor and tar slag is most important.With the use of high pressure aqua ammonia Anthracite coal technique, band
Enter coal dust in tar ammonia mixed liquor, coke powder and tar slag more and more.
The mechanization tar ammonia dreg scraping trough of prior art generally uses ship type mechanization tar ammonia defecator, once divides
Tar, ammoniacal liquor, tar slag are separated out, its volume is big, floor space is big, and separating effect is bad, particularly substantial amounts of tar slag enters
Into the pipeline and storage tank of postorder, often result in pipeline or storage tank is blocked, be forced cleaning of stopping work.It is too frequent due to clearing up, make just
The normal production order is frequently subjected to destruction.
The content of the invention
It is an object of the present invention to provide a kind of mechanization tar ammonia dreg scraping trough, the tar in tar ammonia can be efficiently separated
Slag, shortens disengaging time, improves product quality and disposal ability, solves problem present in background technology.
The technical scheme is that：

With Rolling motor drive connection.
The filter drum that the tar slag discharging opening is located in the top of cell body, filter is located at the middle part in cell body,
Overfall on cell body is close to one end of filter drum.
The screen cloth is provided with screen cloth brush, and the screen cloth brush is fixed on one end of screen cloth brush holder support, screen cloth brush holder support it is another
One end is connected by screen cloth brush holder support fixed pin shaft with screen cloth brush holder support fixed plate, and screen cloth brush holder support fixed plate fixes branch by screen cloth brush holder support
Frame is fixed on housing.
Tangential direction arrangement of the screen cloth brush holder support along filter drum.
The screen cloth is connected between including three sections, adjacent two sections by flange.
Tar slag conveying device is provided with the cell body, the tar slag conveying device includes drive sprocket, scraper plate sprocket wheel
Reductor, board motor, flight chain and driven sprocket are scraped, drive sprocket is fixed on the housing on cell body top, and driven sprocket is solid
On the housing for being scheduled on cell body bottom, drive sprocket is by scraper plate sprocket wheel reductor and scrapes board motor drive connection, drive sprocket and
Driven sprocket is connected by flight chain, and flight chain is provided with scraper plate.
Tar slag discharging opening of the drive sprocket on cell body.
Using the present invention, charging aperture of the tar, ammoniacal liquor and tar slag mixed liquor produced after coal gas cooling on cell body enters
Enter in cell body, the tar ammonia in mixed liquor is entered in filter drum by the screen cloth in filter, through the overflow on cell body
Tar slag in mouth outflow cell body, mixed liquor passes through cell body bottom of the gravitational settling outside filter drum, which part tar slag
It is attached on the screen cloth of filter drum, the tar slag being bonded on the screen cloth of filter drum is removed in time by screen cloth brush,
Screen cloth occlusive effects are avoided to filter.The tar slag of cell body bottom is transported to tar by the flight chain in tar slag conveying device
Slag discharging opening, and send out outside cell body.
The present invention only isolates tar slag and tar ammonia mixture, and tar ammonia mixture then is sent into next procedure
Separated again.
The beneficial effects of the invention are as follows：It can effectively prevent from realizing that solid-state is burnt very well due to the impact of feeding liquid
It is mutually mixed between the dregs of fat, light component ammoniacal liquor and the layering of heavy constituent tar, medium.By increasing filter, can effectively it filter
Bulky grain tar slag, it is not necessary to stratification, the tar slag solid particle in liquid phase just can be removed very well.And Jiao isolated
Oily ammonia water mixture enter after tar and ammonia water separation hopper can stratification, good separating effect is stifled without any pipeline and storage tank
The situation of plug occurs.The small volume compared with existing ship type mechanization tar ammonia defecator, saves floor space；Separating effect
Good, the tar slag content in tar ammonia is low, and feed liquid time of repose is short, and disposal ability is big.
