Change, when spiral plate 55 rotates, the card slot and spiral plate 55 of support plate 7 can be realized close contact, ensure that the steady of support plate 7
It is fixed.
Since No.1 bevel gear 58 is in heeling condition, under the effect of gravity, spiral plate 55 and No.1 bevel gear 58 are easy
It glides, the downslide squeezed to prevent No.1 bevel gear 58 between the upper surface that limited block 8 passes through No.1 gear 53 is protected
It has demonstrate,proved No.1 bevel gear 58 to engage with the normal of No.1 gear 53, has improved the stability of work.
When limited block 8 is rotated with No.1 bevel gear 58, due to the relative rotation between limited block 8 and No.1 gear 53,
Elastic balloon 10 is set to generate compression, the compressed air that elastic balloon 10 generates is sprayed by aeration head 9, accelerates the fortune of absorbing liquid
Dynamic and flue gas disturbance, further improves absorbing liquid to the desulfurization effect of flue gas.
Wind wheel 524 drives shaft 51 to rotate under the drive of wind-force by bevel gear set 525, reduces disappearing for fossil energy
Consumption, reduces costs.
The design of U-typed gas flow 526 and block makes the flue gas in desulfurization chamber 4 need to be through 526 ability of U-typed gas flow
Discharge, the time for retaining the flue gas in desulfurization chamber 4 in desulfurization chamber 4 is longer, extends effective desulfurization of the absorbing liquid to flue gas
Time, desulfurization effect is more preferable, and flabellum 59 is rotated with shaft 51, the convection current of 521 inner air and outer air of fixed cylinder is accelerated, to fixed cylinder
Flue gas in 521 U-typed gas flow 526 plays the effect of cooling.
