Abstract

The invention relates to a vertical multi-drive series connection blade shutter type desulfuration baffle door which comprises a frame, rotating shafts, blades and an electric executing mechanism, andis characterized in that each rotating shaft comprises a lower part shaft, an upper part shaft and an intermediate junction sleeve shaft, wherein the upper part shaft is installed at the upper part of the frame, the lower part shaft is arranged at the lower part of the frame, the intermediate junction sleeve shaft is positioned in the middle of the frame, and the upper part shaft, the lower partshaft and the intermediate junction sleeve shaft are installed on the same axis; and the blades are respectively arranged between the upper part shaft and the intermediate junction sleeve shaft as well as between the intermediate junction sleeve shaft and the lower part shaft which are arranged on the same axis. The door can ensure the installation space of a plurality of driving mechanisms, leadsthe opening of the blades at the upper part and the lower part of the baffle door not to be interfered by each other, and solves the problem of torque transmission caused by the overlong blades.

Description

technical field [0001] The invention relates to a vertical multi-drive serial blade louver type desulfurization baffle door, specifically a desulfurization baffle door suitable for large-scale thermal power plant units such as 600MW and 1000MW ultra-high vertically installed in a horizontal flue, belonging to thermal power generation Plant desulfurization system equipment. Background technique [0002] In the prior art, large-scale thermal power plant units such as 600MW and 1000MW are installed vertically in the desulfurization baffle of the horizontal flue, usually using a series three-axis seat double-blade louver type desulfurization baffle door, a series three-axis seat The double-blade louver type desulfurization baffle door includes blades, rotating shafts, driving actuators, frames, etc. The blades are double-leaf tandem type placed horizontally and horizontally. This kind of door is suitable for horizontal flue. The baffle door is installed vertically and the drivi...
