electric or pneumatic Desulfurization baffle door Anti-corrosion
Overview of desulfurization baffle door products
Desulfurization double louver damper baffle the introduction of
foreign advanced technology production, the desulfurization
absorption tower damper used in flue gas desulfurization system on
the import and export or bypass flue, or used for flue gas
denitration and flue gas dust removal system, the damper usually
adopts the louver double panel structure, shut off when the double
pass into the sealing between baffle, the effect of isolation shut
off the gas.
Desulfurization baffle door performance characteristics
1. A single shaft is used to drive the double-louver baffle
structure, and a sealing chamber is designed in the middle of the
double-layer blades to import sealed air, which is higher than the
flue gas pressure of 500Pa, into the baffle to form a sealed air
isolation layer between the double-layer baffles and block the
passage of smoke flow.
2. The opening and closing time of the damper is less than 60S (it
can be selected according to user requirements).
3. The external design is provided with a linkage mechanism to make
several blades open or close synchronously.
4. Double louver baffle door design structure is reasonable, blade
rigidity is good, stable and reliable operation, louver baffle
blade seal type: elastic seal and gas seal.
5. The double baffle is designed and installed with sealed air
inlet valve. After entering the sealed air, the sealing efficiency
of the baffle door is 100%.
6. Driving mode: pneumatic or electric.
7. The driving device is usually connected with the damper.
8. The electric device adopts mechatronics, has torque protection
and limit device, and can be operated remotely. The electric device
also has hand and electric switching functions for installation,
debugging and maintenance.
9. Connection mode of damper and pipeline: flange seal welding
connection or flange bolt connection.
10. The sealed fan and electric heater of the sealed air system can
be provided by us in complete sets after selection.

desulphurization baffle door description
1. The damper is easy to be corroded due to sulfur dioxide
contained in the air duct, so it is designed and manufactured with
Q235 outsourcing 316L material, which has the characteristics of
temperature resistance, corrosion resistance and long service life.
2. In order to prevent the damper door plate from deforming at high
temperature, reinforcing bars are arranged between the double-layer
plates. The thickness of the single-layer plate is 5mm, and the
total thickness of the damper is 600mm.Damper shaft head, bearing
bush, bearing sleeve and shaft are made of different materials that
are resistant to high temperature, abrasion and corrosion.
3. The electric device is connected to the damper shaft with no
clearance, and the air leakage rate after closing is less than
4. There is a multi-function limit device on the electric device,
and the switch is in place accurately.
5. The distribution cabinet is equipped with DCS interface to
achieve automatic operation effect.
6, with common adjustment, isolation, flexible adjustment,
isolation performance is good.
7, flexible switch, no jam phenomenon, no internal leakage, leakage
phenomenon, good shaft seal.
8. High degree of full automation, with remote, close range and
manual operation functions.
9. The production process conforms to relevant industry standards.
