The specific embodiment
Below in conjunction with Figure of description the present invention is described in detail, but should be noted that enforcement of the present invention is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of integrated apparatus that carries out multiple purifying to containing the stickum dust such as tar, comprise adsorption cleaning unit 1, terminal purifying unit 2, air inlet concetrated pipe 3, all press just segregation section 9, the concetrated pipe 12 of giving vent to anger, ash-pit 14, discharging and discharge system, be provided with between adsorption cleaning unit 1 and the terminal purifying unit 2 and all press just segregation section 9, adsorption cleaning unit 1 opposite side is provided with air inlet concetrated pipe 3, terminal purifying unit 2 opposite sides are provided with the concetrated pipe 12 of giving vent to anger, 1 inside, adsorption cleaning unit is provided with cloth system, 1 bottom, adsorption cleaning unit is connected with discharging and discharge system, and 2 bottoms, terminal purifying unit are provided with ash-pit 14; Described adsorption cleaning unit 1 comprises exhaust gases passes 6, pure qi (oxygen) passage 7, coke adsorbent 4, exhaust gases passes 6 is alternately arranged with pure qi (oxygen) passage 7, the centre is separated by coke adsorbent 4, described exhaust gases passes 6 end part seals, described pure qi (oxygen) passage 7 lower seal, flue gas enter all first segregation section 9 of pressure by pure qi (oxygen) passage 7 ends after passing the coke adsorbent.Coke adsorbent 4 integral body are rectangular structure, are surrounded filling coke between screen, end part seal by the bilateral screen; Coke adsorbent 4 bottoms are connected with the electronic grid type discharge valve 8 of super large load, and top is connected with coke storage tank 10.
Described all pressures just segregation section 9 are the baffle maze structure, are made of the multiple row baffle plate, and adjacent baffle plate is not in same plane, and the baffle plate that each row baffle plate two ends is adjacent is occlusion structure and leaves the slit that flue gas passes through; All pressing just, the segregation section entrance communicates with the pure qi (oxygen) passage of adsorption cleaning unit.In the process of flue dust through segregation section 9 at the beginning of all pressing, larger particles dust in the flue gas is because reduction of speed is weightless and impact in baffle maze, revolution have more dust and drop in the bottom ash-pit 14, flue gas obtains the secondary gravity sedimentation, so far only contain than fine dust in the flue dust, the flue gas after the processing enters clean unit 2.
Flue gas terminal purifying unit 2 adopts Bag filter, and entrance is provided with and all presses just segregation section 9.Described cloth system is positioned at 1 top, adsorption cleaning unit, is comprised of flat coke installation 5, coke storage tank 10, is provided with flat coke installation 5 in the coke storage tank 10, and coke storage tank 10 bottoms are connected with coke adsorbent 4 tops.Discharging and discharge system are comprised of the electronic grid type discharge valve 8 of super large load, coke discharging storage tank 11, electronic grid type discharge valve 13, the electronic grid type discharge valve of super large load 8 upper ends are connected with coke adsorbent 4 bottoms, the lower end is provided with coke discharging storage tank 11, and coke discharging storage tank 11 bottoms are provided with electronic grid type discharge valve 13.
The course of work of this device is: the flue dust that contains the stickum such as tar that produces during by top dress or tamping coke oven coal-charging is because the negative pressure that blower fan produces is sucked up to air inlet concetrated pipe 3 by smoke inlet 15, evenly enter exhaust gases passes 6 after the distribution by air inlet concetrated pipe 3 by inlet valve, the dust that some particles are larger in exhaust gases passes 6 is because gravitational settling of the weightless generation of reduction of speed drops down onto bottom coke discharging storage tank 11; Because exhaust gases passes 6 end part seals, flue dust can only reach by coke adsorbent 4 and all press just segregation section 9 ability incoming terminal clean units 2, in the process of flue dust through coke adsorbent 4, the stickums such as tar are effectively adsorbed, in the process through segregation section 9 at the beginning of all pressing, larger particles dust in the flue gas is because reduction of speed is weightless and impact in baffle maze, revolution have more dust and drop in the bottom ash-pit 14, and flue gas obtains the secondary gravity sedimentation; So far only contain than fine dust in the flue dust, final flue gas enters will be than the fine dust detention at the filter bag outer surface by filter bag with very uniform speed behind the casing in the terminal purifying unit 2, and pure qi (oxygen) is discharged by pure qi (oxygen) outlet 16.
When coke up to specification is carried to coke storage tank 10, start flat coke installation 5, can make coke storage tank 10 increase reserves, guarantee that the renewal of coke is smooth, realize that flue dust does not escape.Finishing by compressed air system of flat coke installation 5 flat burnt processes controlled.
After coke adsorbent 4 two ends pressure reduction increased, the electronic grid type discharge valve 8 of super large load of coke adsorbent 4 and coke discharging storage tank 11 bottoms, electronic grid type discharge valve 13 were opened and are realized coke discharging, upgrade coke adsorbent 4, guarantee the efficient adsorption rate.The coke of discharging is transported outward by automobile.
After resistance of the filter bag rises, by row filter bag is carried out jetting deashing with compressed air, dust is shaken off, and is down to voluntarily in the bottom ash-pit 14, effluxes after treatment.
The integrated purifying apparatus structure that coke absorption+gravitational settling of the present invention+bag-type dusting multiple purifying is processed is reasonable, remarkably productive, easy to maintenance, can make flue dust obtain absorption, cooling, purification without escape ground.Stratum granulosum material convenient sources can guarantee thoroughly to solve coke oven coal-charging smoke to the bonding difficult problem of cleaner, and the processing of special flue dust is obtained multiple efficacies.
