DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0029] Reference Figure 1 The preferred embodiment of the utility model provides a gas turbine oil mist separator, comprising: an outer shell 10 with a cavity, a traction fan 20 connected to the outer shell 10, and a manual pressure regulating assembly 30. A filter element assembly and a partition 40 are also provided in the outer shell 10 to separate the cavity into an air intake chamber 101, a filter chamber and an exhaust chamber 104, and the air intake chamber 101 and the filter chamber are connected through the filter element assembly located therebetween, and the filter chamber and the exhaust chamber 104 are connected through the traction fan 20. A pressure regulating port is provided on the partition 40 that penetrates the plate surface, and the exhaust chamber 104 is connected with the air intake chamber 101 through the pressure regulating port provided on the partition 40 located therebetween. The manual pressure regulating assembly 30 is rotatably provided in the exhaust chamber 104, so as to adjust the area of ​​the pressure regulating port blocked by the manual pressure regulating assembly 30 during the rotation process, and then adjust the opening of the pressure regulating port to adjust the pressure of the air intake chamber 101.

[0030] When the gas turbine oil mist separator of the utility model is working, the oil mist to be treated first enters the air inlet chamber 101 from the oil tank under the action of the traction fan 20, enters the filter chamber after being filtered by the filter component, and then enters the exhaust chamber 104 from the filter chamber through the traction fan 20. The oil mist is separated after being acted upon by the filter component, and the separated oil is located in the filter component and finally flows back to the oil tank, while the filtered air is discharged into the atmosphere from the exhaust chamber 104.

[0031] In the gas turbine oil mist separator of the utility model, a pressure regulating port penetrating the plate surface is provided on the partition plate 40, and a manual pressure regulating assembly 30 is provided in the exhaust chamber 104. The manual pressure regulating assembly 30 can adjust the area of ​​the pressure regulating port blocked by the manual pressure regulating assembly 30 during rotation, and then adjust the opening of the pressure regulating port to adjust the pressure of the intake chamber 101, and finally adjust the pressure in the oil tank to be suitable for lubricating oil systems with different pressure requirements, and the manual pressure regulating assembly 30 has simple adjustment operation, high adjustment accuracy and reliability; and by adjusting the opening of the pressure regulating port, the pressure difference between the intake chamber 101 and the exhaust chamber 104 is controlled to ensure the negative pressure inside the oil tank. During normal operation, the opening of the pressure regulating port is adjusted to ensure that the negative pressure in the oil tank is within the design range. The manual pressure regulating assembly 30 of the device has a wide pressure regulation range and is suitable for lubricating oil systems with different negative pressure requirements of the oil tank.

[0032] Alternatively, if Figure 1 and Figure 4 As shown, the manual pressure regulating assembly 30 includes a mounting seat 31 fixed on the first side plate 11 of the exhaust chamber 104, an adjusting rod group 32 threadedly penetrated in the mounting seat 31, and a pressure regulating valve 33 used to cover the pressure regulating port to adjust its opening. The first end of the adjusting rod group 32 is located outside the exhaust chamber 104, and the second end thereof is axially extended into the exhaust chamber 104 and penetrates the partition 40 before extending into the air inlet chamber 101. The pressure regulating valve 33 is located in the exhaust chamber 104 and is fixed on the outer circle of the adjusting rod group 32, so as to be close to the partition 40 and located on the first side wall of the exhaust chamber 104, thereby adjusting the area covered by the pressure regulating port during the rotation process to adjust the opening of the pressure regulating port. When the manual pressure regulating assembly 30 is operated to regulate the pressure, first hold the first end of the regulating rod group 32 to rotate the regulating rod group 32. When the regulating rod group 32 rotates, the pressure regulating valve 33 is driven to rotate synchronously. The pressure regulating valve 33 is also pressed against the first side wall of the partition 40 under the action of the regulating rod group 32. When the pressure regulating valve 33 rotates, the area of ​​the pressure regulating port blocked by it can be adjusted, and then the opening of the pressure regulating port can be adjusted to adjust the pressure of the air inlet chamber 101.

[0033] In this alternative, combined with Figure 5As shown, there are multiple pressure regulating ports, which are arranged at intervals along the circumference, and each pressure regulating port is arranged in a fan shape. The pressure regulating valve 33 includes a mounting frame 331 fixed on the outer circle of the adjusting rod group 32, and a pressure regulating plate 332 fixed on the side end of the mounting frame 331. The pressure regulating plate 332 is provided with multiple connecting ports 3320 corresponding to the multiple pressure regulating ports. When the adjusting rod group 32 rotates, the pressure regulating plate 332 is driven to rotate synchronously. When the connecting ports 3320 on it correspond to the pressure regulating ports one by one, the opening of the pressure regulating port is the largest. As the pressure regulating plate 332 rotates, its plate surface will gradually cover the pressure regulating port, so that the opening of the pressure regulating port can be adjusted, and finally the pressure in the air inlet chamber 101 can be adjusted.

[0034] In this option, if Figure 4 As shown, the first side plate 11 is also provided with a mounting hole that penetrates the plate surface, the mounting seat 31 is sealed and installed in the mounting hole, and an internal threaded through hole is provided in the mounting seat 31. The adjusting rod group 32 includes a mounting rod 321 that penetrates the internal threaded through hole, a nut 322 that is fixed on the outer circle of the mounting rod 321 and threadedly connected to the internal threaded through hole, a driving handle 323 that is fixed to the first end of the mounting rod 321, and a limiting member 324 that is provided at the second end of the mounting rod 321. The pressure regulating valve 33 is fixed on the outer circle of the mounting rod 321. The limiting member 324 is located in the air inlet cavity 101, and is used to limit the second side of the partition plate 40 located at the air inlet cavity 101.

[0035] In a specific embodiment of this optional solution, Figure 4 As shown, the limiting member 324 includes a baffle 3241, a flat washer 3242 and an elastic circlip 3243 which are sequentially mounted on the outer circle of the second end of the mounting rod 321, and the elastic circlip 3243 is fixed by a groove provided on the mounting rod 321. The baffle 3241 presses against the second side surface of the partition 40 under the action of the elastic circlip 3243, and the flat washer 3242 is clamped between the baffle 3241 and the elastic circlip 3243. The limiting member 324 is used to prevent the mounting rod 321 from falling off the partition 40, thereby improving the reliability of the manual pressure regulating assembly 30.

[0036] Preferably, if Figure 4 As shown, the manual pressure regulating assembly 30 further includes a force spring 34, which is located in the exhaust cavity 104 and mounted on the outer circle of the regulating rod group 32, and the two ends of the force spring 34 are respectively connected to the mounting seat 31 and the pressure regulating valve 33. The force spring 34 is used to keep the pressure regulating valve 33 close to the partition 40, thereby improving the stability and reliability of the manual pressure regulating assembly 30.

[0037] Optionally, not shown in the figure, the partition 40 is also provided with a mounting port that penetrates the plate surface. The gas turbine oil mist separator also includes an automatic pressure regulating assembly for automatically adjusting the pressure of the air inlet chamber 101, and the automatic pressure regulating assembly includes: an automatic flap that is sealed and installed in the mounting port, and a hinge for hingedly connecting the automatic flap to the partition 40. The hinge is connected to the first side surface of the partition 40 and is connected to the automatic flap, so that the automatic flap is close to the sealed mounting port when the oil mist separator is in normal working state, and when the filter element assembly is blocked and the pressure of the air inlet chamber 101 increases, the automatic flap is turned toward the exhaust chamber 104 to release the pressure. In this optional scheme, the opening pressure of the automatic flap can be controlled by selecting hinges of different angles, and the automatic pressure regulating assembly also includes a limiter connected to the first side surface of the partition 40, and the limiter is used to abut against the automatic flap, thereby adjusting the maximum opening of the automatic flap. During normal operation, the pressure in the air intake chamber 101 is lower than the pressure in the exhaust chamber 104, and the automatic flap is closed. When the filter element assembly is blocked or abnormal, causing the pressure in the air intake chamber 101 to be higher than the exhaust chamber 104, the automatic flap opens to prevent the pressure in the fuel tank from being too high, and the opening pressure of the automatic flap is lower than the high alarm value of the pressure in the fuel tank.

[0038] Alternatively, if Figure 2 and Figure 3 As shown, the filter assembly includes a primary filter assembly 60 and a secondary filter assembly 70. The filter chamber includes a primary filter chamber 102 and a secondary filter chamber 103 separated by the primary filter assembly 60 and the secondary filter assembly 70, and the air inlet chamber 101 and the primary filter chamber 102 are connected through the primary filter assembly 60 located therebetween, and the primary filter chamber 102 and the secondary filter chamber 103 are connected through the secondary filter assembly 70 located therebetween, and the secondary filter chamber 103 is located above the primary filter chamber 102. The secondary filter chamber 103 is also connected to the exhaust chamber 104 through the traction fan 20. In this optional solution, by adopting a primary filter component 60 and a secondary filter component 70 which are arranged in sequence along the flow direction of the oil mist, that is, by two-stage filtration, the filtration efficiency is improved, and the oil and gas in the exhausted air are greatly reduced. The filter element of the primary filter component 60 is inexpensive, which can increase the service life of the fine filter element. The separated oil returns to the oil tank, and the gas is discharged into the atmosphere, thereby reducing the consumption of lubricating oil and avoiding environmental pollution. Moreover, since the gas contains almost no oil and gas, it can be applied to offshore platforms and petrochemical industry projects, thereby improving applicability.

[0039] In this option, if Figure 2As shown, a mounting frame is also provided in the primary filter chamber 102, and an inlet and outlet for the primary filter assembly 60 to pass through and communicate with the mounting frame are provided on the second side plate 12 of the primary filter chamber 102. The primary filter assembly 60 is slidably mounted on the mounting frame by the inlet and outlet, and the outer end is sealed and connected to the inlet and outlet. In this optional solution, the primary filter assembly 60 adopts a demister, and the drawer-type installation method of the demister is convenient for timely replacement.

[0040] In this option, if Figure 3 As shown, a mounting base plate 80 is further provided between the primary filter chamber 102 and the secondary filter chamber 103, and a plurality of air inlets penetrating the plate surface are provided on the mounting base plate 80. The secondary filter assembly 70 includes a plurality of secondary filter elements 71, each of which is vertically supported on the mounting base plate 80 and detachably fixed to the mounting base plate 80 by a fixing assembly 90 connected to the mounting base plate 80.

[0041] In a specific embodiment of this optional solution, Figure 3 As shown, the fixing assembly 90 includes a limit plate 91 fixed on the lower surface of the mounting base plate 80 and arranged corresponding to the air inlet, a stud 92 vertically inserted into the air inlet, a limit block 93 fixed to the bottom end of the stud 92, a cover plate 94 connected to the upper end of the stud 92, and a butterfly nut 95. The secondary filter element 71 is vertically mounted on the correspondingly arranged stud 92. The cover plate 94 is located above the secondary filter element 71, and the butterfly nut 95 is used to pull the stud 92 axially upward during the rotation process, so that the limit block 93 presses against the limit plate 91 to limit the position, and presses the cover plate 94 to the top of the secondary filter element 71. In this specific embodiment, when replacing the secondary filter element 71, the cover plate 94 above the secondary filter cavity 103 is removed, and the butterfly nut 95 is loosened to replace the filter element. The filter element is simple to install, easy to replace, and convenient to maintain. Single and multiple filter elements can be replaced.

[0042] Alternatively, if Figure 1-3As shown, the gas turbine oil mist separator also includes an exhaust pipe 110 arranged on the outer shell 10 and connected to the exhaust chamber 104, and a flame arrester 120 arranged at the end of the exhaust pipe 110. The flame arrester 120 is used to reduce the oil and gas content in the oil mist and prevent external sparks from entering the oil mist separator, thereby making the new device suitable for offshore platforms and petrochemical industry projects. Optionally, a differential pressure transmitter is also installed between the primary filter chamber 102 and the secondary filter chamber 103 to determine whether the fine filtration filter element is blocked; a through hole connected to the air inlet of the traction fan 20 is opened on the third side panel of the secondary filter chamber 103, and the gas turbine oil mist separator also includes a guide baffle, which is arranged on the inner side surface of the third side panel to form a guide channel for collecting the oil mist with the third side panel, and the guide channel is connected to the through hole; the traction fan 20 sucks the filtered air in the secondary filter chamber 103 into the exhaust chamber 104, and the oil mist in the secondary filter chamber 103 is collected to the guide baffle under the suction force of the traction fan 20, and the air in the exhaust chamber 104 is discharged into the air through the exhaust pipe 110.
