Abstract

The invention provides a method for dragging a cement production line rotating machine by adopting a steam turbine. The method comprises the steps: A, a driving part of the rotating machine adopts the steam turbine; B, a steam boiler produces steam and fees the steam into the steam turbine through a pipe; C, the steam turbine drives the rotating machine to rotate; D, dead steam produced by the steam turbine in working is discharged into a coagulator; E, water coagulated by the coagulator is fed into a deaerator; F, deoxidized water in the deaerator is fed into a deoxidizing water tank; G, water in the deoxidizing water tank is fed into the steam boiler; H water in the steam boiler is heated to form steam and the steam is fed into the steam turbine. A high-power high-voltage electric motor is replaced by the steam turbine, the output rotation speed and power of the steam turbine can be adjusted by adjusting the steam quantity of the boiler, the power requirement of the rotating machine is met, stepless speed regulation is achieved, energy consumption is reduced, and throttle and low-efficiency loss caused by process parameter adjustment in the cement production process are reduced.

Description

technical field [0001] The invention belongs to the technical field of cement production, and in particular relates to a method in which a rotating machine of a cement production line is driven by a steam turbine. Background technique [0002] With the development of our country's economy and the progress of society, energy saving and consumption reduction have increasingly become the further goals pursued by most enterprises. Reducing product costs is also the main means to improve the competitiveness of enterprises. [0003] At present, high-voltage motors are used as the only driving method for large-scale rotating machinery on the cement production line of dry precalcined rotary kiln, and the large amount of power consumed has become an important cost factor in cement production. Contents of the invention [0004] The purpose of the present invention is to provide a method of replacing the driving motor of the cement production line with a steam turbine to reduce the e...
