The invention discloses an ascending
pipe type gas rising cap for removing fine particles in
sintering flue gas towers. The ascending
pipe type gas rising cap comprises a gas rising cap; the gas rising cap comprises a gas inlet, an arc-shaped blocking plate, a gas outlet, a
barrel and a top plate; the gas inlet is formed in the bottom of the
barrel, the arc-shaped blocking plate is arranged at thetop of the side wall of the
barrel, the gas outlet is formed in the side wall of the barrel, the top plate is arranged at the top of the barrel, the gas rising cap is installed on a liquid collectingbottom plate, and the liquid collecting bottom plate is installed on the supporting frame. According to the ascending
pipe type gas rising cap, the stress direction of vertical spraying liquid on thewaterproof blocking plate is changed; the problems of
water leakage and liquid leakage of the gas lifting cap are solved; mixing of
tower body spraying
slurry with
sieve plate layer and
demister layer cleaning liquid can be prevented, the uniform distribution effect of the
flue gas is improved, an effective gas-liquid distribution process can be formed, part of soluble salt and
aerosol in the
flue gas can be further removed, the stability and safety of
system operation are improved, the treatment pressure of wet electric
precipitation is reduced, and finally the ultralow
emission standard isachieved.
