Abstract
A high efficiency and energy saving discharge air device relates to the structure improvement of a discharge air duct. The invention relates to the discharge air device which has high efficiency and energy conservation, and can improve the service life of the blower. The discharge air device comprises a blower and a fire tube. The discharge air device is structurally characterized in that: an air inlet pipe is arranged on the sideward wall of the fire tube; the outlet of the air inlet pipe is arranged on the exhaust direction of the fire tube; a contraction pipe with big inlet and small outlet is arranged above the outlet of the air inlet pipe.
Description
Technical field:
The present invention relates to the improvement of exhaust duct structure.
Background technology:
The flue gas that is produced in the existing plant produced, behind Fig. 3 gas skirt 200, smoke pipe 100, the flue gas after fly-ash separator 300 focuses on is discharged through induced draft fan 400, chimney 500 more usually; Concentrate purifying treatment because a plurality of gas skirts 200 are set, main smoke pipe road is increased, therefore, strengthened the resistance of ducting, increased the loss of the energy; For example: certain electrolytic aluminium factory has 106 electrolytic furnaces, and 106 electrolyzers are set altogether, and used power of fan is 3000KW.In addition, in the smoke evacuation process, the condensation of high-temperature flue gas, containing a large amount of dust in the flue gas all has bigger wearing and tearing to draught fan impeller, has reduced the work-ing life of blower fan.
Summary of the invention:
The present invention is exactly at the problems referred to above, and a kind of efficient, energy-conservation, air exhausting device that can improve fan life is provided.
The present invention adopts following technical scheme: the present invention includes blower fan, smoke pipe, the wall of the side of its structural feature smoke pipe is provided with blast pipe, and the air draft direction of smoke pipe is provided with the outlet of blast pipe; Outlet top be provided with import big, go out young collapsible tube.
Beneficial effect of the present invention:
1, efficient, energy-conservation:
Because the present invention has adopted the wall of the side of smoke pipe to be provided with blast pipe, the air draft direction of smoke pipe is provided with the outlet of blast pipe; Outlet top be provided with import big, go out young collapsible tube; Utilize jet current principle, with less air quantity rapidly, the discharge of big air quantity has not only improved the efficient of air draft greatly, and has saved a large amount of energy in the guiding smoke pipe, (can reduce power of fan 5-8 doubly); For example, concentrate the former 3000KW blower fan of using of electrolytic aluminium factory that purifies, the present invention can replace with the small power blower fan of 400～600KW;
2, improve fan life:
The present invention utilizes jet current principle, by the blast pipe of low power blower fan is set, the flue dust in the smoke pipe is discharged; And the impeller in the different all the time blower fans of flue dust in the smoke pipe contacts, and can not cause the wearing and tearing to draught fan impeller, therefore, compares with the blower fan of air draft in the past, has improved the life-span of blower fan.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is user mode figure of the present invention;
Fig. 3 is existing concentrated dust outlet geometry synoptic diagram.
Embodiment:
The present invention includes blower fan 1, smoke pipe 2, the wall 3 of the side of smoke pipe 2 is provided with blast pipe 4, and the air draft direction of smoke pipe 2 is provided with the outlet 5 of blast pipe 4; Export 5 tops be provided with import big, go out young collapsible tube 6.
The outlet of blast pipe 4 can be small-bore jet pipe; To increase the jet effect of blast pipe 4.
Collapsible tube 6 can be fixed in the smoke pipe 2 by three support plates 7.
Can be provided with secondary collapsible tube 8 on the collapsible tube 6, secondary collapsible tube 8 is made up of collapsible tube 9, trunnion 10, amplifying tube 11 successively from the bottom to top, can further increase the air draft effect.
During use, smoke pipe 2 of the present invention links to each other with gas skirt 14, fly-ash separator 13 with smoke exhaust pipe 12 respectively, and blower fan 1 links to each other with each smoke pipe 2; After collapsible tube 6, the secondary collapsible tube 8 of flue gas in the gas skirt 14 in smoke pipe 2 guided, to fly-ash separator 13, smoke exhaust pipe 12 discharges.
