Description
Technical field
The present invention relates to a kind of control system, more particularly, to one kind production CO Bypass Control Systems.
Background technology
Existing CO Bypass Control Systems are generally two-stage reciprocating compressor control system；The compressor is mainly used in
Craft in Chemical Industrial Area SLIC chemical plant will be delivered to after the gas compression of 99%CO；Will be from technical process CO gas (pressure
0.5MPaG) enter after carbon monoxide compressor 2-1702CM01 and 2-1702CM02 compresses through two sections as supply source of the gas and boost
To 1.6MPaG.In order to ensure outlet pressure stabilization, compressor designs a manually-operated gate pressure regulation, when outlet pressure PT02 is high
When 1.6MPaG, PV01 valves are adjusted manually, part CO returns to suction port of compressor by compressor outlet.The design defect is：1.
The change of pressure process can not be followed and changed.2. have certain delayed by hand valve regulation, cause outlet pressure pulsations compared with
Greatly.3. waste of manpower resource.
The content of the invention
The purpose of the present invention be exactly provided for the defect for overcoming above-mentioned prior art to exist it is a kind of ensure entrance and
The pressure in exit, the production CO Bypass Control Systems for reducing pressure oscillation.
The purpose of the present invention can be achieved through the following technical solutions：
One kind production CO Bypass Control Systems, control the pressure of carbon monoxide compressor, including pneumatic control valve, PID
Controller and value selector high,
The two ends of described pneumatic control valve are connected with admission line and outlet pipe respectively,
Described PID controller is provided with two, is separately positioned on admission line and outlet pipe, monitors and admission line
And the pressure of carbon monoxide compressor that outlet pipe is connected,
Described high level selector signal connection PID controller and pneumatic control valve, obtains according to PID controller monitoring
Pressure control pneumatic regulating valve.
Described carbon monoxide compressor is provided with two, is connected with admission line and outlet pipe respectively, two one oxidations
Connecting pipe is provided between carbon compressor.
The CO gases that admission line is imported are led after carrying out two-part compression through two carbon monoxide compressors by outlet pipe
Go out.
The inlet pressure of carbon monoxide compressor is less than 0.5MPaG, PID of the pneumatic control valve through being connected at admission line
Controller controls pressure regulation.
The outlet pressure of carbon monoxide compressor is higher than 1.6MPaG, PID of the pneumatic control valve through being connected at outlet pipe
Controller controls pressure regulation.
Compared with prior art, present invention can ensure that the pressure in entrance and exit, and it is swift in response, it is delayed
It is small, it is not only able to save manpower, the fluctuation of outlet pressure can also be reduced.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure, 1 is carbon monoxide compressor, 2 is admission line, 3 is outlet pipe, 4 is PID controller, 5 is pneumatic tune
Section valve, 6 are value selector high.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.

And outlet pipe 3 is connected, connecting pipe is provided between two carbon monoxide compressors 1.The two ends of pneumatic control valve 5 respectively with enter
Feed channel 2 and outlet pipe 3 are connected, and PID controller 4 is provided with two, are separately positioned on admission line 2 and outlet pipe 3, prison
The pressure of the carbon monoxide compressor 1 that survey is connected with admission line 2 and outlet pipe 3, the signal of value selector high 6 connection PID
Controller 4 and pneumatic control valve 5, the pressure control pneumatic regulating valve 5 for obtaining is monitored according to PID controller 1.
The present invention when in use, under any circumstance, after compressor stops, bypass valve by with 2% speed from current
Aperture open to 100% rapidly.After carbon monoxide compressor 1 starts, stable process conditions are waited, click on DCS pictures LOAD
After Compressor buttons, bypass valve is closed to inlet pressure control (PT01) and gone out with 1% speed from 100% aperture
The maximum of mouth Stress control (PT02).
The CO gases that admission line is imported are led after carrying out two-part compression through two carbon monoxide compressors by outlet pipe
Go out, when normally controlling, the inlet pressure of carbon monoxide compressor 1 is less than 0.5MPaG, and pneumatic control valve 5 is through being connected to air inlet pipe
The control pressure regulation of PID controller 4 at road 2.The outlet pressure of carbon monoxide compressor 1 is higher than 1.6MPaG, and pneumatic control valve 5 is passed through
It is connected to the control pressure regulation of PID controller 4 at outlet pipe 3.
