specific Embodiment 1

[0035] The screw compressor based on the direct drive of the steam turbine in this embodiment has a structural schematic diagram as figure 1 shown. The screw compressor based on the direct drive of the steam turbine includes a driving steam turbine 5 and a screw compressor 8; the mechanical output end of the driving steam turbine 5 is connected with the mechanical input end of the screw compressor 8 through a coupling 6; A rotational speed sensor 7 is arranged at the connection part between the mechanical output end and the mechanical input end of the screw compressor 8;

[0036] The steam inlet of the driving steam turbine 5 is provided with a steam inlet valve 2, the steam inlet valve 2 is provided with a servo motor 1 for controlling the opening size of the valve, and the steam inlet is also provided with a steam inlet opening hand wheel 4 and a steam turbine emergency stop device 3;

[0037] The screw compressor 8 is connected to the oil-gas separator 15; the top of the ...

specific Embodiment 2

[0052] The method of the steam turbine directly driving the screw compressor of the present embodiment adopts the following steps to realize:

[0053] Step a, calibration of the relationship between the pressure standard value at the output end of the gas cooler 11 and the speed standard value of the speed sensor 7;

[0054] Step b, the speed sensor 7 collects the actual speed value of the mechanical output end of the driving steam turbine 5, and transmits it to the driving steam turbine PLC17;

[0055] Step c, driving the steam turbine PLC17 to compare the speed standard value of step a with the actual speed value of step b;

[0056] Step d, drive the steam turbine PLC17 to control the servo motor 1, and:

[0057] The actual speed value is greater than the standard speed value, and the steam turbine PLC17 is driven to control the servo motor 1, so that the steam inlet valve 2 reduces the air intake of the steam inlet;

[0058] The actual speed value is equal to the speed st...

Abstract

A screw compressor directly driven by a steam turbine and a driving method thereof belong to the field of mechanical control, and specifically relate to a mechanical device and a control method for a screw compressor directly driven by a steam turbine; the driving steam turbine and the screw compressor are connected through a coupling, and set There is a speed sensor, by monitoring the speed at the mechanical output end of the driving steam turbine and the air pressure at the output end of the screw compressor, and feeding back to the steam inlet of the driving steam turbine, the steam turbine directly drives the screw compressor; the present invention is based on the screw compressor directly driven by the steam turbine and the driving This method can not only save energy, but also reduce costs.

Description

technical field [0001] A screw compressor directly driven by a steam turbine and a driving method thereof belong to the field of mechanical control, and specifically relate to a mechanical device and a control method for a screw compressor directly driven by a steam turbine. Background technique [0002] The traditional motor-driven screw compressor is an indirect drive mode, and a set of power systems is set between the motor and the screw compressor. Because the power system has energy consumption and needs to cooperate with power distribution facilities, it has the disadvantages of wasting energy and high cost. Contents of the invention [0003] In order to solve the above problems, the present invention designs a device in which a steam turbine directly drives a screw compressor, and discloses a control method for a steam turbine directly driving a screw compressor. The present invention can not only save energy, but also reduce costs. [0004] The purpose of the pres...
