Embodiment Construction
[0022] In the first aspect of the embodiments of the present invention, a compressor system with a steam-electric dual drive is proposed, figure 1 It shows a schematic structural diagram of a steam-electric dual-drive compressor system according to an embodiment of the present invention. Such as figure 1 The compressor system shown includes: a compressor body 10; a variable frequency motor 20, which is connected to the compressor body 10 through a first coupling 30, and the variable frequency motor 20 is used to drive the compressor body 10 to start at no-load; a steam turbine 40 and the overrunning clutch 50. The steam turbine 40 is connected to the compressor body 10 through the overrunning clutch 50. The steam turbine 40 uses surplus steam to work. The overrunning clutch 50 engages when the working speed of the steam turbine 40 is greater than or equal to the working speed of the compressor body 10, and When the speed of the steam turbine 40 is lower than the working speed of...

The present invention provides a compressor system and a control method of a steam-electric dual-drive. The compressor system includes: a compressor body; a variable frequency motor connected to the compressor body through a first coupling; The steam turbine is connected to the main body of the compressor, and the steam turbine uses the surplus steam to work. The overrunning clutch is engaged when the working speed of the steam turbine is greater than or equal to the working speed of the compressor body, and disengaged when the speed of the steam turbine is lower than the working speed of the compressor body, so that the steam turbine and the frequency conversion The motor cooperates to drive the compressor body; the CCS controller of the comprehensive control system of the turbine compressor is connected with the compressor body, the steam turbine and the frequency conversion motor respectively. The invention adopts the CCS controller to control the frequency conversion motor and the steam turbine to cooperate to drive the compressor system to work, and the steam turbine uses surplus steam to work, which reduces the consumption of electric energy and saves the use cost.
Description
Technical field [0001] The invention relates to the field of compressor control, and in particular to a compressor system and a control method of a steam-electric dual drive. Background technique [0002] In recent years, with the increasing depletion of energy and global warming, energy conservation and emission reduction have become an urgent task for all countries. [0003] The driving method of the compressor currently used mainly relies on electric drive. Regarding compressor power consumption and high cost, it has always been one of the biggest production burdens of compressor users. Although, with the continuous development and innovation of science and technology, the industry has tried to save power through frequency conversion technology, but due to the limitations of different working conditions, the effect of frequency conversion technology on the actual power saving of users is difficult to achieve the expected effect. Therefore, how to achieve real and effective pow...
