Description
The utility model belongs to boiler fixture, is specially the heat energy increment device for abatement of smoke and dust that can improve boiler thermal output.
At present the general boiler thermal output of China is generally about 65%, Ma Shi process of cleaning and water film dedusting method are adopted in smoke abatement and dust control more, because of these method effects undesirable, boiler exhaust gas also must lean on tens meters to up to a hundred meters chimney to high altitude discharge, and this high altitude discharge does not fundamentally solve flue dust, lime-ash, SO
2Deng pollution to environment.Combustible in the flue gas does not obtain recycling yet simultaneously.
The utility model adopts the chemical dust arrester of secondary and combustible gas takes place, retracting device, is intended to obtain better smoke medicining dust-removing effect, and improves the thermal efficiency of boiler simultaneously.
Below in conjunction with accompanying drawing the each several part primary structure is described.Fig. 1 is the utility model general assembly schematic diagram.The drawing left side is the spray for dust suppression tower, and bottom, the right is liquefaction smoke elimination tower, and top is gas separator.The spray for dust suppression tower is provided with in vertical direction, mainly constitute by conical dirt pocket (3) and spray chamber (6), be provided with the spiral flue (2) that links to each other with boiler flue gas outlet (1) in the dirt pocket, the dirt pocket bottom is connected with a laying dust chamber (5) by ring flange (4), top is connected with the spray chamber, lining, spray chamber (6) has been horizontally disposed with three layers of dividing plate (7), (8), (9), has circle, rhombus or rectangle sieve aperture on the dividing plate.Be respectively equipped with high-pressure nozzle (11), (12) that communicate with solution line between (7), (8) and (8), (9) dividing plate, this high-pressure nozzle can bear 8k.g/cm
2Pressure, according to boiler tonnage difference, 2 tons, 4 tons, 6 tons, 8 tons boilers adopt No. 1 spiral nozzle (32) as shown in Figure 3, No. 2 leaf wing nozzles (33), No. 3 covering of the fan nozzles (34), No. 4 plum blossom nozzles (35) respectively.Top, spray chamber links to each other with mixed flue gas road (12), and then by air-introduced machine (13), induced duct (14) links to each other with liquefaction smoke elimination tower.Liquefaction smoke elimination tower and the gas separator that is attached thereto be layout in vertical direction also.The liquefaction smoke elimination tower first half is liquefaction smoke elimination chamber (16), and the bottom is No. two laying dust chambers (18) that link to each other by gate (17).The liquefaction smoke elimination is provided with the spiral flue (15) that communicates with induced duct (14) in the chamber, top is connected to running water pipe (21), overflow pipe (20) and solution funnel (22), the indoor middle part of liquefaction smoke elimination hangs is equipped with a hydrogen generator (19), hydrogen generator is mainly combined alternately by aluminium ring and zinc ring, its outside is the semiclosed cover of the tubular of a lower ending opening, and the cover top links by hydrogen delivery tube (24) device separated from the gas (25).See accompanying drawing 2, gas separator is mainly by absorption of hydrogen pipe (30), gas separation chamber (29), baffle plate (31) is formed, absorption of hydrogen pipe chamber inner separated from the gas isolates, it only communicates with gas recovery pipe (27), and gas separation chamber top links to each other with low latitude aiutage (26), and the side also communicates with gas recovery pipe (27).
The utility model is realized smoke abatement and dust control, the course of work that combustible reclaims is summarized as follows: flue gas enters spiral flue (2) from boiler flue gas outlet (1), under the effect of air-introduced machine, flue gas moves in spiral flue high speed, at the bottom of the agency part grit landing tower by centrifugal force and gravity, then enter the spray chamber, part flue dust and high-pressure nozzle (10), (11) Pen Chu vaporific aqueous chemical solution is clashed into mutually grit is dropped to the laying dust chamber, and part of smoke is fully mixed generation semiwater gas and a small amount of cracking hydrogen with the vaporific aqueous vapor of chemical solution, SO
2Deng, under the air-introduced machine effect, this part mist enters mixed flue gas road (12), the spiral flue (15) that enters liquefaction smoke elimination chamber through induced duct (14) forms the high speed swirling eddy fully to be mixed with the chemical solution of adding the smoke elimination chamber (16) of liquefying and produces series of chemical, with the absorption dropping to of the sulfide in flue gas laying dust chamber, and react with hydrogen generator, produce hydrogen partial, enter absorption of hydrogen pipe (seeing (30) in the accompanying drawing 2) in the gas separator by hydrogen delivery tube (24), after other mist enters the gas separation chamber (29) of gas separator through mixed flue gas road (23), under the effect of baffle plate, (see (31) in the accompanying drawing 3) and make that the part fuel gas is by the difference of proportion and be separated, other flue gas enters atmosphere by the aiutage (26) that device separated from the gas top links to each other, isolated fuel gas then enters gas recovery pipe (27), hydrogen in the absorption of hydrogen pipe is isolation with mist in gas separator, after entering gas recovery pipe (27), mix with isolated so gas, under the effect of air blast (28), the input boiler furnace carries out second-time burning.So far finished the recycling of secondary chemistry smoke abatement and dust control and combustible.
The utility model can make the smoke abatement and dust control of boiler reach 0～1 grade of Lin Geman black and white concentration, and the tail gas dustiness drops to 0.19kg/h, dust concentration 63.76mg/m
3, be significantly less than the 200mg/m of national regulation
3, smoke evacuation only needs the low latitude aiutage with several meters high to get final product SO
2Absorptivity reaches 71.36%, compares with general water dust scrubber, Ma Shi deduster, and the utility model can economize on water 85%.In addition, the recovery of combustible and carry out second-time burning, not only itself burn and emit heat energy, the more important thing is and to improve the burner hearth combustion position, play combustion-supporting effect, fuel is burnt more fully, after measured, the utility model can make carbon content in the cinder drop to 4～5% by original 35～40%, makes saving coals from boiler 20～30%.
