Description
Technical field
The utility model relates to compression separation equipment, particularly oil and gas separating system.
Background technique
The single-screw air compressor oil and gas separating system used in colliery is primarily of PLC control section and Oil-gas Separation part composition.Oil-gas Separation part comprises deaerator, safety valve, compressor, suction tude, steam outlet pipe, pressure gauge with electric contact, pressure gauge, safety valve; The effect of deaerator is separated by the oil gas entered, and is provided with suction port and air outlet simultaneously, for air inlet with give vent to anger; Compressor is connected with suction port by suction tude, and the effect of compressor is the oil gas that compression needs to be separated, the effect of suction tude be by compression after oil-gas transportation to deaerator inside; Steam outlet pipe is connected with air outlet, and the effect of steam outlet pipe is discharged by the gas after being separated; Pressure gauge with electric contact is arranged on deaerator inside and is connected with PLC control section, and pressure gauge with electric contact can detect the air pressure of deaerator and pressure signal is passed to PLC system; Safety valve is arranged on deaerator top, and its effect discharges a part of oil gas when deaerator air pressure inside is too high, ensures that deaerator is in substitute pressure; Pressure gauge is arranged on steam outlet pipe, for detecting air pressure of giving vent to anger.PLC control section can gather the signal of Oil-gas Separation partial interior and control the air compressor, deaerator, safety valve etc. of Oil-gas Separation partial interior, such as, gather the pressure gauge with electric contact superpressure Continuity signal in deaerator and control safety valve.
Because the pressure gauge in steam outlet pipe can only test pressure value, some electrical signal can not be transmitted as pressure gauge with electric contact in deaerator, in addition, safety valve relies on contained spring and carries out superpressure action, when the frequent superpressure action of deaerator, may occur that contained spring lost efficacy, spring is once weakness, safety valve also can lose efficacy, exceed standard even if air pressure tested by pressure gauge, stop oil gas portions to go forward side by side pedestrian's pressure release if not timely by PLC control section, will the blast of deaerator be caused.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of oil and gas separating system, and when safety valve lost efficacy, during deaerator inner overpressure, oil and gas separating system can stop automatically, avoids causing the situation of the blast of deaerator because safety valve lost efficacy.
For solving the problem, the technical solution adopted in the utility model is: oil and gas separating system, comprise PLC control section and Oil-gas Separation part, Oil-gas Separation part comprises deaerator, safety valve, compressor, suction tude, steam outlet pipe, first pressure gauge with electric contact, deaerator is provided with suction port and air outlet, compressor is connected with suction port by suction tude, steam outlet pipe is connected with air outlet, first pressure gauge with electric contact is arranged on deaerator inside and is connected with PLC control section, safety valve is arranged on deaerator top, also comprise the second pressure gauge with electric contact, described second pressure gauge with electric contact is arranged in steam outlet pipe and is also connected with PLC control section.
The beneficial effects of the utility model are: change general purpose pressure gauge in original steam outlet pipe into pressure gauge with electric contact, when steam outlet pipe pressure superpressure, pressure gauge with electric contact can in time by signal transmission to PLC control section, and then PLC control section performs stopping in time, avoid the danger of deaerator blast.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model Oil-gas Separation part.
Number in figure: 1 is deaerator, and 2 is safety valve, and 3 is compressor, and 4 is suction tude, and 5 is steam outlet pipe, and P1 is the first pressure gauge with electric contact, and P2 is the second pressure gauge with electric contact.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The pressure gauge being positioned at steam outlet pipe in traditional oils gas separating system can only test pressure, when there is superpressure, PLC control section can not be made to perform some emergency action (as stopped Oil-gas Separation part).For solving foregoing problems, the utility model changes the pressure gauge being positioned at steam outlet pipe into pressure gauge with electric contact, as Fig. 1, the utility model comprises PLC control section and Oil-gas Separation part, Oil-gas Separation part comprises deaerator 1, safety valve 2, compressor 3, suction tude 4, steam outlet pipe 5, first pressure gauge with electric contact P1, second pressure gauge with electric contact P2, on deaerator, 1 is provided with suction port and air outlet, compressor 3 is connected with suction port by suction tude 4, steam outlet pipe 5 is connected with air outlet, first pressure gauge with electric contact P1 is arranged on deaerator 1 inside and is connected with PLC control section, safety valve 2 is arranged on deaerator 1 top, second pressure gauge with electric contact P2 is arranged in steam outlet pipe 5 and is also connected with PLC control section.Specific practice is: the second pressure gauge with electric contact P2 is often driven auxiliary contact and access in PLC control; when deaerator 1 internal pressure exceedes setting value, the second pressure gauge with electric contact P2 conducting, by signal to PLC; PLC performs and shuts down and report to the police, and plays the object of overpressure protection action.
Oil and gas separating system working principle is as follows: oil gas to be separated compresses by compressor 3, oil gas after compression is delivered into the suction port of deaerator by suction tude 4, and then oil gas is separated in deaerator 1 inside, period first pressure gauge with electric contact P1 can monitor the air pressure of deaerator 1 inside, when the air pressure of deaerator 1 inside exceedes setting value, first pressure gauge with electric contact P1 conducting, by signal to PLC, PLC performs and starts safety valve 2, and then deaerator 1 pressure release in time, gas after separation is discharged eventually through air outlet and steam outlet pipe 5.Second pressure gauge with electric contact P2 can monitor the pressure in steam outlet pipe 5, and when the setting value of air pressure in steam outlet pipe 5 more than the second pressure gauge with electric contact P2, signal, by conducting, performs to PLC, PLC and shuts down and report to the police by the second pressure gauge with electric contact P2 in time.
