Description
Technical Field
The utility model relates to a contain sour gas processing apparatus field, concretely relates to high sour gas reciprocating compressor midbody discharging equipment that contains.
Background
The sulfuric acid gas-containing pressurizing station is abroad, the periphery of the station yard is sparse, unattended, and the middle body is discharged into the atmosphere directly. For example, the compressor booster station (H2S: 5.6-6.5%) of Enkana (ENCANA) company, the middle body is directly discharged into the atmosphere, and the station has no supporting facilities such as emergency evacuation broadcasting and the like.
The similar high-sulfur-content gas compressor is not applied at home. The domestic high-sulfur acid gas gathering station is basically an attended station, and along with the reduction of the pressure of a gas well, pressurization and outward transportation are needed in the later period.
The middle body of the conventional reciprocating compressor is directly discharged into the atmosphere at a high point, but in the using process of the acid gas reciprocating compressor, high-sulfur-containing acid gas in a cylinder enters the middle body through sealing, if the high-sulfur-containing acid gas is directly discharged, the concentrations of H2S, CO2, CH4 and the like in the air are increased, toxic, combustible and other gas alarms can be caused at the initial stage, along with the abrasion of the sealing of the compressor, the leakage amount is increased, and the risk of H2S poisoning, explosion and the like easily occurs in the region.
However, the pressure of the station flare pipe network is far greater than the discharge pressure (micro-positive pressure) of the midbody, so that the midbody cannot be connected into the flare pipe network for safe emptying.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a can improve the discharge pressure of reciprocating compressor midbody to reach reciprocating compressor midbody discharge gas and can insert station yard torch pipe network, thereby reach the high sour gas containing of safe emission purpose and discharge device midbody of reciprocating compressor.
In order to realize the purpose, the utility model provides a technical scheme is:
the utility model provides a high sour gas containing reciprocating compressor midbody discharging equipment, includes the reciprocating compressor midbody, and the end of giving vent to anger of the reciprocating compressor midbody passes through pipeline and torch pipe network intercommunication, installs pressure indication controller on the pipeline, and the high pressure input end and the pressurized gas of ejector advance the pipe intercommunication, and the pressurized gas advances to manage and installs the control valve, pressure indication controller and control valve interlocking control, install the check valve on the pipeline, the suction end and the pipeline of ejector pass through the intercommunication pipeline intercommunication, the nozzle and the torch pipe network intercommunication of ejector.
Specifically, station high-pressure purified combustible gas is introduced into the pressurized gas inlet pipe.
Specifically, the station high-pressure purified combustible gas is natural gas.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses, simple structure can improve the discharge pressure of the body among the reciprocating compressor to reach the body exhaust gas and can insert station yard torch pipe network among the reciprocating compressor, thereby reach the safe emission purpose, simultaneously, can reflect the leakage quantity that lets out of filler according to the change of pressure, can in time change the filler.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, the high-sulfur-content acid gas reciprocating compressor middle body discharge device comprises a reciprocating compressor middle body 1, wherein an air outlet end of the reciprocating compressor middle body 1 is communicated with a torch pipe network 8 through a conveying pipeline 2, a pressure indication controller 3 is installed on the conveying pipeline 2, a high-pressure input end of an ejector 6 is communicated with a pressurized air inlet pipe 4, a control valve 5 is installed on the pressurized air inlet pipe 4, the pressure indication controller 3 and the control valve 5 are in interlocking control, a check valve 7 is installed on the conveying pipeline 2, a suction end of the ejector 6 is communicated with the conveying pipeline 2 through a communicating pipeline 9, and a nozzle of the ejector 6 is communicated with the torch pipe network 8.
Station high-pressure purified combustible gas is introduced into the pressurization gas inlet pipe 4, and the station high-pressure purified combustible gas is natural gas.
During the use, when body 1 discharges the atmospheric pressure and is less than torch pipe network 8 pressure in reciprocating compressor, pressure indication controller 3 makes control valve 5 open, and the pressurized gas gets into ejector 6 in and spout at ejector 6 inside nozzle, forms the efflux, produces the entrainment and flows, forms the negative pressure zone, body 1 discharge gas mixes after being inhaled in reciprocating compressor, carries out the momentum exchange, and the speed is gradually balanced in the flow process, discharges into torch pipe network 8 after the pressure risees, and the establishment of check valve 7 ensures that the torch backpressure can not flow backwards in reciprocating compressor body 1.
When the discharge pressure of the body 1 in the reciprocating compressor is higher than the pressure of the flare pipe network 8, the pressure indication controller 3 closes the control valve 5, pressurized gas is cut off, and the discharged gas directly enters the flare pipe network 8 through the check valve 7.
The pressure indication controller 3 monitors the pressure in the conveying pipeline 2, simultaneously feeds back the change of the pressure of the discharge air of the reciprocating compressor middle body 1, and reflects the increase of the leakage amount of the packing when the pressure rise is larger than a set value, and prompts the replacement of the packing seal.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
