Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail, but it 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 to carrying out multiple purifying containing stickum dust such as tar, comprise adsorption cleaning unit 1, terminal purifying unit 2, air inlet concetrated pipe 3, all pressure just segregation section 9, to give vent to anger concetrated pipe 12, ash-pit 14, discharging and discharge system, be provided with between adsorption cleaning unit 1 and 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 side is provided with concetrated pipe 12 of giving vent to anger, adsorption cleaning unit 1 inside is provided with cloth system, adsorption cleaning unit 1 bottom is connected with discharging and discharge system, terminal purifying unit 2 bottom is 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 and pure qi (oxygen) passage 7 are alternately arranged, centre is separated by coke adsorbent 4, described exhaust gases passes 6 end part seal, described pure qi (oxygen) passage 7 lower seal, flue gas enters all pressure just segregation section 9 through after coke adsorbent by pure qi (oxygen) passage 7 end.Coke adsorbent 4 entirety is rectangular structure, is surrounded, filling coke between screen, end part seal by bilateral screen; Coke adsorbent 4 bottom is 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 baffle maze structure, are made up of 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 gap that flue gas passes through; All the first segregation section entrance of pressure communicates with the pure qi (oxygen) passage of adsorption cleaning unit.At flue dust in the process of all pressing just segregation section 9, larger particles dust in flue gas is because reduction of speed is weightless and impact in baffle maze, revolution have more dust and drop in bottom ash-pit 14, flue gas obtains secondary gravity sedimentation, so far only contain comparatively fine dust in flue dust, the flue gas after process enters clean unit 2.
Flue gas terminal purifying unit 2 adopts Bag filter, and entrance is provided with all pressure just segregation section 9.Described cloth system is positioned at adsorption cleaning unit 1 top, is made up of flat coke installation 5, coke storage tank 10, is provided with flat coke installation 5 in coke storage tank 10, and coke storage tank 10 bottom is connected with coke adsorbent 4 top.Discharging and discharge system are made up of the electronic grid type discharge valve of super large load 8, coke discharging storage tank 11, electronic grid type discharge valve 13, super large load electronic grid type discharge valve 8 upper end is connected with coke adsorbent 4 bottom, lower end is provided with coke discharging storage tank 11, is provided with electronic grid type discharge valve 13 bottom coke discharging storage tank 11.
The course of work of this device is: the negative pressure produced due to blower fan by the flue dust containing stickums such as tar produced when top dress or tamping coke oven coal-charging is sucked up to air inlet concetrated pipe 3 by smoke inlet 15, enter exhaust gases passes 6 after being uniformly distributed by inlet valve by air inlet concetrated pipe 3, the dust that some particles are larger in exhaust gases passes 6 drops down onto bottom coke discharging storage tank 11 because reduction of speed weightlessness produces a gravitational settling; Due to exhaust gases passes 6 end part seal, flue dust by coke adsorbent 4 and can only all press just segregation section 9 ability incoming terminal clean unit 2, at flue dust in the process of coke adsorbent 4, the stickums such as tar are effectively adsorbed, in the process through all pressing just segregation section 9, larger particles dust in flue gas is because reduction of speed is weightless and impact in baffle maze, revolution have more dust and drop in bottom ash-pit 14, and flue gas obtains secondary gravity sedimentation; So far in flue dust only containing comparatively fine dust, final flue gas to enter in terminal purifying unit 2 after casing with very uniform speed by filter bag will comparatively fine dust detention be at filter bag outer surface, and pure qi (oxygen) exports 16 by pure qi (oxygen) and discharges.
When coke up to specification is carried to coke storage tank 10, start flat coke installation 5, coke storage tank 10 can be made to increase reserves, ensure that the renewal of coke is smooth, realize flue dust and do not escape.Flat the completing of burnt process of flat coke installation 5 is controlled by compressed air system.
After coke adsorbent 4 two ends pressure reduction increases, the electronic grid type discharge valve of super large load 8 of coke adsorbent 4 and coke discharging storage tank 11 bottom, electronic grid type discharge valve 13 are opened and are realized coke discharging, upgrade coke adsorbent 4, ensure efficient adsorption rate.The coke of discharging is transported outward by automobile.
After resistance of the filter bag rises, carry out jetting deashing to filter bag by row with compressed air, dust is shaken off, and is down in bottom ash-pit 14 voluntarily, after treatment outer row.
The integrated purifying apparatus structure of coke absorption+gravitational settling of the present invention+bag-type dusting multiple purifying process is reasonable, remarkably productive, easy to maintenance, and flue dust can be made to obtain absorption, cooling, purification without escape.Stratum granulosum material convenient sources, can guarantee thoroughly to solve the bonding difficult problem of coke oven coal-charging smoke to cleaner, obtain multiple efficacies to the process of special flue dust.
