Description
Technical Field

The natural gas long-distance pipeline needs to establish a booster station along the way, and realizes the long-distance transportation of the natural gas through the multistage compression of the compressor. The compressor is the heart transported by the natural gas pipeline, the safety and the reliability of the operation of the compressor are related to whether the unit can stably work for a long period, and once the unit breaks down due to sealing, the downstream gas supply is directly influenced. In order to prevent or inhibit natural gas from leaking into the atmosphere along the rotary shaft end of the compressor and maintain the normal operation of a compressor main machine, a sealing device is arranged at the shaft end of the compressor in the prior art, so that the consumption of materials and energy can be effectively reduced, the environmental pollution is prevented, and the safety of equipment is protected.
The dry gas sealing system at the shaft end of the compressor is one of important technologies, but solid or liquid impurities in a long-distance natural gas transmission pipeline can cause damage to a dynamic ring and a static ring of a dry gas seal if entering the dry gas sealing system of the centrifugal compressor, so that a dry gas sealing filter element of a compressor unit of a gas station of the gas transmission pipeline is frequently replaced, the service life of the dry gas sealing filter element is shortened, the leakage rate of natural gas is increased, the compressor is stopped, the safe operation of the compressor unit is seriously influenced, and the damage is caused to precision equipment such as a downstream pressure regulator, a downstream flowmeter and the like. Therefore, if the natural gas quality cannot meet the air inlet requirement of the dry gas sealing system of the compressor, the dry gas sealing system cannot ensure the safe operation of the compressor unit.
In order to ensure the normal operation of the dry gas sealing system of the natural gas long-distance pipeline station compressor, a gravity separator or a cyclone separator is usually arranged in front of a filtering separator of the station compressor dry gas sealing gas source pretreatment system, so that the burden of the filtering separator is favorably reduced, and the service life of the dry gas sealing travel is prolonged.
The existing dry gas sealing gas source has the characteristics of low flow rate and high pressure, and the pressure loss of natural gas caused by a dry gas sealing system of a compressor is required to be small in order to reduce energy loss in the conveying process.
The existing direct-flow cyclone dust collector utilizes the rotation of air flow to enable impurities in the air flow to be centrifuged to the periphery, the air in the central part is taken and conveyed to the next process, the impurities in the peripheral part are discharged together with the air, so a large amount of target air loss is caused, the discharged impurity-containing air needs additional cost for secondary purification, the pressure loss is large, and due to the limitation of the pipe length of the direct-flow cyclone dust collector, some impurities moving close to the axis in the traditional direct-flow cyclone dust collector are not separated under the action of centrifugal force in time, the air directly enters the exhaust pipe of the direct-flow cyclone dust collector, and the dust removal efficiency of the direct-flow cyclone dust collector is low.
