Abstract

The invention discloses a desulphurized flue gas damper. The desulphurized flue gas damper is characterized in that the damper comprises a valve body and pulling plates; the pulling plates are evenly arranged on the valve body; bearings are arranged on the valve body; the pulling plates are connected to the bearings; an electric actuating mechanism is arranged on the left side of the top end of the valve body; a proximity switch is arranged on the side, connected with the electric actuating mechanism, of the valve body; a rotor is arranged at the bottom end of the electric actuating mechanism; the rotor is connected with rotary shafts; the bearings are arranged on the rotary shafts; the electric actuating mechanism is connected with the valve body through connection of the rotor and the rotary shafts; and pulling rods are connected with the rotary shafts. According to the desulphurized flue gas damper provided by the invention, the desulphurized flue gas dampers are mounted at an inlet, an outlet and bypasses of a desulphurized flue gas unit, flue gas can be effectively intercepted or can circulate in a flue gas pipeline, and the good airtightness and corrosion resistance are achieved.

Description

technical field

[0001] The invention relates to a baffle door, in particular to a flue gas desulfurization baffle door in a flue gas pipeline. Background technique

[0002] In today's highly industrialized world, people need a clear sky. However, the thermal power generation industry and the metallurgical industry discharge a large amount of sulfur-containing gas from the flue, which forms acid rain and causes serious pollution to the atmosphere. The flue gas desulfurization unit can process the sulfur-containing gas in the flue. However, once the unit fails, the flue gas in the flue will not be treated and will leak, and the toxic gas that pollutes the atmosphere will still be discharged. Although the flue gas baffle door can cut off the leakage of flue gas, it is still unsatisfactory when it is in use. However, the existing flue gas baffle door has poor sealing performance, poor anti-corrosion performance, unstable operation, single control mode, and The post-maintenance...
