Problems solved by technology

[0006] Purpose of the invention: This patent is to solve the problem that the induced draft fan needs to be driven simultaneously or independently driven by the steam turbine and the asynchronous motor after the combined transformation of the induced draft fan and the desulfurization booster fan in the thermal power plant, and the electrical corrosion that may occur after the unit is put into operation , uneven heating of the rotor and other hidden dangers, and then provides a fully automatic clutch device and application method for the integrated transformation unit of the induction and booster, which is more suitable for the transformation of the induced draft fan and the desulfurization booster fan in thermal power plants. High integration, more complete functions, high load capacity, can be flexibly applied to high-speed, heavy-duty working conditions

Abstract

The invention relates to a full-automatic clutching device for a drawing and pressurizing integration modification unit and an application method. The full-automatic clutching device for the drawing and pressurizing integration modification unit comprises an asynchronous motor adaptor flange, an insulating coupler, a shell, an output connecting shaft, a sixth bearing, a third frame body, a fifth bearing, a position detecting sensor, a synchronous automatic clutch, a transmission shaft, a fourth bearing, an oil outlet, a large gear, a third bearing, a jigger, a second bearing, an input connecting shaft, a second frame body, a small gear, an oil inlet, a first frame body and a first bearing. The unit is applied to an air drawing fan and a turbine unit, the hidden danger problems that after aturbine and an asynchronous motor are used in the unit at the same time, electro-corrosion possibly occurs, a rotor is heated unevenly and bent are prevented and solved, the integration degree is high, the function is more complete, the bearing ability is high, and the device can be flexibly applied to working conditions of high speed and heavy loads and is more applicable to the modification unit integrating the air drawing fan and a desulfuration and pressurization fan of a thermal power plant.

Description

technical field [0001] The invention relates to a combined transformation unit of an induced draft fan and a desulfurization booster fan in a thermal power plant, in particular to a fully automatic clutch device and an application method for the combined transformation unit of an induced draft fan and a desulfurization booster fan. Background technique [0002] According to national environmental protection requirements, new thermal power plants should simultaneously build desulfurization and denitrification devices, and the flue gas will be discharged into the atmosphere after passing through the desulfurization and denitrification devices. A power plant built two 1000MW ultra-supercritical coal-fired units in 2010. The desulfurization and denitrification devices were installed simultaneously in the project, and the induced draft fan and booster fan were installed separately. The pressure head of the booster fan overcomes the resistance of the desulfurization system. [000...
