Problems solved by technology

The device used to control the opening and closing of the baffle door in the prior art has a complex structure, and the opening and closing of the baffle door needs to be realized through a large torque. In order to provide a large torque, the device used to provide torque in the prior art The driving mechanism usually includes a driving shaft on which a reversing baffle is fixed, and the driving shaft realizes torque transmission under the action of external power. There are problems with this integral driving structure: one is that it is inconvenient to install on the shell In the body, it is troublesome to disassemble and assemble, and the other is that the subsequent transfer and maintenance are more cumbersome

Abstract

The invention belongs to the technical field of gas turbine power station units, and relates to a flue gas damper, in particular to a flue gas damper driving mechanism. The flue gas damper driving mechanism comprises a front support seat arranged at the front end of a three-way shell and a rear support seat arranged at the rear end of the three-way shell, the front support seat and the rear support seat are arranged coaxially, a front shaft is rotationally connected on the front support seat, a rear shaft is rotationally connected on the rear support seat, connection ends of the front shaft and the rear shaft both extend into the three-way shell, two ends of a torque tube are fixed on the rear shaft and the front shaft respectively, and reversing baffles are welded on the torque tube. The flue gas damper driving mechanism is simple and reasonable in structure, is technically improved focusing on the problems of flue gas damper driving devices in the prior art, and is effectively suitable for controlling opening and closing of the flue gas damper.

Description

technical field [0001] The invention belongs to the technical field of gas turbine power plant units, and relates to a smoke baffle door, in particular to a smoke baffle door driving mechanism. Background technique [0002] The core component in the waste heat utilization system is the three-way flue gas baffle door, which can lead the flue gas into the waste heat boiler or the bypass chimney, that is, the boiler side baffle is closed, and the flue gas is introduced into the bypass chimney; or the chimney side baffle Closed, the flue gas is introduced into the waste heat boiler, but at least one of the two outlets must be open. Precise control of the two outlets is required so that one is always on and the other off. The device used to control the opening and closing of the baffle door in the prior art has a complex structure, and the opening and closing of the baffle door needs to be realized through a large torque. In order to provide a large torque, the device used to pr...
