Abstract
The utility model relates to a flue gas desulphurization damper door in the flue gas pipeline, which comprises a valve body and shutter baffle plates, wherein a pneumatic device is arranged on the lower end of the valve body, valve shafts are connected with the valve body, the shutter baffle plate is connected with the valve shaft, each valve shaft can be connected with the pneumatic device by a connecting rod and a crank, and the pneumatic device on the lower end of the valve body is connected with a plurality of valve shafts; a support baffle plate and a sealing spring plate are connected on the shutter baffle plate to baffle the flue gas leakage. Since the utility model adopts the pneumatic device to drive the shutter baffle plates to fast rotate in 90 degrees simultaneously, so the shutter baffle plates is led to open or close and the operation is reliable; the utility model has long service life, and facilitates the installation, maintenance and repair of the flue gas desulphurization unit.
Description
Technical field the utility model relates to valve, relates in particular to the flue gas desulfurization baffle door in the flue.
Background technology is in today of industrialization high development, and people need a bright day.Yet thermal power generation industry and metallurgy industry have been discharged the gas of a large amount of sulfur-bearings in the flue, and it forms acid rain, causes serious pollution to atmosphere.The flue gas desulfurization unit can be handled the sulfurous gas in the flue, and still, in case after this unit broke down, the flue gas in the flue can not get handling and produces and leak, what discharge is still the toxic gas that pollutes the atmosphere.Though and gas baffle door can block the leakage of flue gas, still still unsatisfactory in use, and existing gas baffle door can not satisfy the requirement of desulfurization unit fully because sealing is relatively poor.
Utility model content the purpose of this utility model is: a kind of flue gas desulfurization baffle door is provided, it is installed in import, outlet, the bypass place of flue gas desulfurization unit, and it is a kind of valve that blocks flue gas or allow the flue gas circulation and have good sealing property and anti-corrosive properties in flue.
A kind of flue gas desulfurization baffle door comprises the blinds baffle plate on valve body, the valve body; It is characterized in that:
A pneumatic means is arranged on the lower end of valve body, valve shaft is connected on the valve body, and the blinds baffle plate is connected on the valve shaft, and each valve shaft links to each other with pneumatic means by connecting rod, crank, the pneumatic means of valve body lower portion links to each other with the some valve shafts in bottom, and support catch, sealing shell fragment are connected on the blinds baffle plate.
Described framework outside is provided with floor and fagging, and material is an explosive clad plate.
The material of described blinds baffle plate is an explosive clad plate, and the two sides is provided with corrosion-inhibiting coating.
Described support catch, sealing shell fragment are made of stainless steel.
Advantage of the present utility model is as follows:
1, make 90 ° of quick rotation simultaneously because the utility model adopts pneumatic means can drive a plurality of blinds baffle plates, make a plurality of blinds baffle plates open or close, it is reliable.
2, because support catch and sealing shell fragment are set on the blinds baffle plate of the present utility model; When the blinds flapper closure, support catch and sealing shell fragment and can guarantee that sealing is tight; But spacer medium reaches not have and leaks.
3, because the utility model is installed in the import of flue gas desulfurization unit, outlet, bypass place, when unit maintenance, can in flue, block flue gas, guarantee that flue gas does not have leakage, make unit maintenance, easy to maintenance.
