As shown in fig. 1 and 3, some embodiments of the present invention provide an anti-surge apparatus, which is mainly applied to avoid a surge phenomenon of a compressor. The apparatus comprises a pipe 100, a pressure equalizer 200 and at least one flow conduit 300.
It is understood that the number of flow conduits 300 may be any number, one, two, or more than two.
Wherein the flow guide pipe 300 is arranged on the outer wall of the pipeline 100, and both ends of the flow guide pipe 300 are communicated with the pipeline 100. Specifically, one end of the flow guide tube 300 is close to the air inlet 110 of the pipeline 100, one end of the flow guide tube 300 close to the air inlet 110 of the pipeline 100 is communicated with the pressure equalizing pipe 200, and the other end of the flow guide tube 300 is close to the air outlet 120 of the pipeline 100.
One side of each of the flow guide pipes 300 is provided with a check valve 400, and the check valve 400 is arranged at one side of the flow guide pipe 300 close to the air inlet 110. It should be noted that the check valve 400 prevents the airflow entering the duct 100 from flowing to the air outlet 120 through the flow guide tube 300, so that the airflow from the air outlet 120 can flow into the flow guide tube 300 through the end of the flow guide tube 300 close to the air outlet 120 of the duct 100 and be discharged from the end of the flow guide tube 300 close to the air inlet 110 of the duct 100.
Specifically, when the pressure at the inlet 110 of the duct 100 is lower than the pressure at the outlet 120 of the duct 100, a reverse thrust is generated. It is understood that, at this time, the airflow in the duct 100 at the air outlet 120 thereof flows in the opposite direction, i.e., toward the air inlet 110, by installing the flow guide tube 300 at the outer side of the duct 100.
Since the guide tube 300 is provided with the check valve 400, the flow of air in the pipe 100 is prevented by the check valve 400 from entering the guide tube 300 through the end of the guide tube 300 near the air inlet 110 of the pipe 100. Therefore, the airflow flowing from the inlet 110 to the outlet 120 cannot pass through the flow guide tube 300, and it can be understood that, after the flow guide tube 300 is added, the pressure in the pipeline 100 is equal to that when the flow guide tube 300 is not added in the process that the airflow in the pipeline 100 normally flows from the inlet 110 to the outlet 120.
In addition, the air flow in the duct 100 can flow into the flow guide tube 300 through the end of the flow guide tube 300 near the air outlet 120 of the duct 100, and flow through the check valve 400 to be discharged from the end of the flow guide tube 300 near the air inlet 110 of the duct 100.
It can be understood that, when the pressure at the inlet 110 of the pipeline 100 is lower than the pressure at the outlet 120 of the pipeline 100, the airflow at the outlet 120 is guided to the inlet 110 through the flow guide pipe 300 to reduce the pressure at the outlet 120 of the pipeline 100, and at the same time, the pressure at the inlet 110 of the pipeline 100 is increased to reduce the pressure difference between the inlet 110 and the outlet 120 of the pipeline 100, so that the airflow resistance at the outlet 120 of the pipeline 100 is converted into the airflow power at the inlet 110 of the pipeline 100, thereby eliminating the occurrence of surge during low-load operation of the centrifugal impeller and ensuring the safe operation of the centrifugal impeller.
The check valve 400 is a valve in which the opening and closing member is a circular flap and operates by its own weight and the pressure of the medium to block the reverse flow of the medium. The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards.
In addition, the pressure equalizing pipe 200 is disposed on an inner wall of the pipe 100 and is close to the air inlet 110.
In this embodiment, the pressure equalizing pipe 200 is an annular pipe, and the pressure equalizing pipe 200 is communicated with one end of the flow guiding pipe 300 close to the air inlet 110.
Meanwhile, a plurality of spaced exhaust holes are formed in the pressure equalizing pipe 200, so that when gas flowing into the pressure equalizing pipe 200 is exhausted through the exhaust holes, the pressure of the gas flow at the exhaust holes is increased.
By directing each of the exhaust holes toward the outlet 120, the direction of the airflow discharged from the exhaust holes is the same as the direction of the airflow flowing from the inlet 110 to the outlet 120 in the duct 100, i.e., the pressure of the inlet 110 is increased.
The number of the exhaust holes can be two or more than two arbitrary numbers, and can be specifically set according to actual conditions.
In this embodiment, the pressure equalizing pipe 200 is a ring pipe, the exhaust holes are arranged at intervals on one side of the pressure equalizing pipe 200 facing the air outlet 120, and the distances between the centers of any two adjacent exhaust holes are equal. The plurality of exhaust holes are uniformly arranged to improve the uniformity of the pressure at the inlet 110 of the pipeline 100.
In some embodiments of the present invention, as shown in fig. 1, a regulating valve 500 is disposed at one side of each of the flow guide pipes 300.
The regulating valve 500 is disposed between an end of the draft tube 300 near the air outlet 120 and the check valve 400 to regulate the pressure in the draft tube 300 by the regulating valve 500.
It should be noted that when the pressure at the air inlet 110 in the pipeline 100 is not less than the pressure at the air outlet 120 in the pipeline 100, no air flows in the flow guide pipe 300.
When the pressure at the inlet 110 of the pipeline 100 is lower than the pressure at the outlet 120 of the pipeline 100, the air flow at the outlet 120 flows into the flow guide tube 300 under the action of the pressure, and then flows through the regulating valve 500 and the check valve 400 in sequence, and flows into the pipeline 100 from the end of the flow guide tube 300 close to the inlet 110 of the pipeline 100.
It should be noted that, at this time, the pressure in the flow guide pipe 300 can be adjusted by controlling the opening degree of the adjusting valve 500, so as to adjust the pressure of the air flowing from the flow guide pipe 300 to the air inlet 110, and thus adjust the pressure at the air inlet 110.
As shown in fig. 1 to 5, in some embodiments of the present invention, the flow guide tube 300 is multiple, and the flow guide tube 300 is disposed at intervals around the circumference of the duct 100.
In this embodiment, the number of the flow guide tubes 300 is four, the distance between the axes of any two adjacent flow guide tubes 300 is equal, and the distance from the axis of each flow guide tube 300 to the axis of the pipeline 100 is equal, so that the uniformity of pressure adjustment at the air inlet 110 of the pipeline 100 through the flow guide tubes 300 is improved by uniformly distributing the flow guide tubes 300 in the circumferential direction of the pipeline 100, and the stability of the air flow in the pipeline 100 is improved.
By increasing the number of the flow guide pipes 300, the efficiency of adjusting the pressure at the air inlet 110 and the air outlet 120 is improved.
In addition, the number of the draft tubes 300 communicating with the pipeline 100 can be controlled by controlling the opening degree of the regulating valve 500, and it can be understood that no air flows through the draft tubes 300 when the regulating valve 500 is closed.
It should be noted that the regulating valve 500 can regulate the flow passage area and the pressure gradient according to different models.
As shown in fig. 1, fig. 2 and fig. 5, in some embodiments of the present invention, the inner wall of the pipe 100 is further provided with a guide vane 600, the guide vane 600 is rotatably disposed with the inner wall of the pipe 100, and it should be noted that an axis of a rotating shaft of the guide vane 600 is perpendicular to an axis of the pipe 100.
The guide vane 600 is located between the air inlet 110 and the pressure equalizing pipe 200.
In this embodiment, the guide vanes 600 are plural, and the plural guide vanes 600 are disposed on the inner wall of the duct 100 at intervals, wherein the number of the guide vanes 600 can be specifically set according to actual conditions.
The guide vanes 600 form an annular linkage guide vane type valve on the inner wall of the pipeline 100, and it should be noted that the rotation direction and the rotation angle of each guide vane 600 are the same, that is, each guide vane 600 rotates synchronously.
It should be noted that the pressure at the air inlet 110 is adjusted by adjusting the opening degree of the guide vane 600.
Specifically, when the pressure at the inlet 110 is greater than the pressure at the outlet 120 of the duct 100, the opening of the guide vane 600 may be increased to increase the airflow rate in the duct 100.
When the pressure at the inlet 110 is equal to the pressure at the outlet 120 of the duct 100, the opening of the guide vane 600 may be decreased to increase the pressure at the inlet 110, so as to prevent the airflow in the duct 100 from flowing reversely.
When the pressure at the inlet 110 is lower than the pressure at the outlet 120 of the pipeline 100, the opening of the guide vane 600 may be decreased to increase the pressure at the inlet 110, and at the same time, the opening of the control valve 500 may be controlled to adjust the pressure of the airflow flowing through the flow guide pipe 300, and the pressure of the airflow discharged from the end of the flow guide pipe 300 close to the inlet 110 of the pipeline 100 may be adjusted to increase the pressure at the inlet 110 of the pipeline 100.
The opening of the guide vane 600 is reduced to adjust the flow area of the air inlet 110, increase the dynamic pressure of the air inlet 110 of the pipeline 100, and reduce the dynamic pressure of the reverse airflow in the pipeline 100, thereby improving the stability of the airflow in the pipeline 100.
As shown in fig. 2 and 3, in some embodiments of the present invention, a nozzle 700 is disposed on one side of the pressure equalizing tube 200, each nozzle 700 is respectively communicated with one of the exhaust holes, and the outlet of each nozzle 700 faces the air outlet 120, so as to adjust the pressure at the air inlet 110 of the pipeline 100 through the nozzle 700.
It should be noted that, the number of the nozzles 700 is equal to the number of the exhaust holes, and by arranging a plurality of spaced nozzles 700 on the circumference of the side of the pressure equalizing pipe 200 facing the air outlet 120 of the pipeline 100, the outflow direction of the nozzles 700 is along the direction of the positive working air flow in the pipeline 100, so as to ensure that the pressure and the range of each nozzle 700 on the circumference of the pressure equalizing pipe 200 are the same, improve the uniformity of pressure adjustment at the air inlet 110 of the pipeline 100, and improve the stability of pressure adjustment at the air inlet 110 of the pipeline 100.
The direction of the positive working air flow in the duct 100 refers to a direction in which the air in the duct 100 flows from the inlet 110 of the duct 100 to the outlet 120 of the duct 100.
Some embodiments of the present invention further provide a compressor including the anti-surge apparatus of any one of the above embodiments, wherein the air inlet 110 is disposed on a pressure expansion chamber at a rear end of a centrifugal impeller of the compressor, and the air outlet 120 is connected to a condenser of the compressor to guide a medium compressed by the compressor to flow to the condenser through a pipe 100.
It should be noted that the guide vanes 600 are located at the outlet of the centrifugal impeller, and the opening degree of each guide vane 600 is synchronously controlled by the guide vane switch at the inlet of the centrifugal impeller.
The outlet of the centrifugal compressor is communicated with the air inlet 110, the unidirectional circumferential forward airflow nozzle 700 is arranged at the air inlet 110, the outflow direction of the nozzle 700 is along the forward working airflow direction, when the centrifugal compressor works under low load, high-pressure media at the air outlet 120 flows through the pressure equalizing pipe 200 through the flow guide pipe 300 and is sprayed out from the nozzle 700, power is provided for the airflow at the air inlet 110, and therefore the working medium at the outlet of the centrifugal impeller is prevented from flowing backwards, and surging of the compressor can be avoided.
Wherein the centrifugal impeller is arranged at the outlet of the centrifugal compressor.
Through the dynamic and static pressure conversion mechanism, when the pressure at the air outlet 120 is higher than the pressure at the air inlet 110, the nozzle 700 is located behind the guide vane 600 and in the vortex negative pressure area, so that the high-pressure gas at the air outlet 120 is guided to the low-pressure area through the reverse guide pipe 300 by utilizing the pressure gradients of the two sections, namely the high-pressure gas at the air outlet 120 is guided to the air inlet 110 through the guide pipe 300, and resistance is changed into power, so that the surge of the compressor is eliminated.
