[0032] The application discloses an air outlet device for an oil-gas separator. The application discloses an air outlet device for an oil-gas separator. In the embodiment, the air outlet device is used for setting on the oil-gas separator, and the main structure 10 of the air outlet device has a communication cavity 11, an air inlet part 12 and an air outlet part 13, the air inlet part 12 and the air outlet part 13 are communicated with the communication cavity 11, and the air inlet part 12 is communicated with an air outlet 101 of the oil-gas separator. A heat preservation structure 20 is sleeved on the main structure 10, and an air outlet cavity 21 is formed around at least part of an inner wall of the heat preservation structure 20 and an outer peripheral surface of the main structure 10, and the air outlet cavity 21 is communicated with the outside. A heating structure 30 is arranged on the main structure 10 to heat the main structure 10. The main structure 10 further has a vent hole 14, and the communication cavity 11 and the air outlet cavity 21 are communicated with the vent hole 14 to discharge the gas in the communication cavity 11 into the air outlet cavity 21. In this way, the oil-gas separator discharges the separated gas to the outside through the air outlet device, and the main structure 10 is heat preserved by the heat preservation structure 20 in a low-temperature environment, so that the temperature of the gas in the communication cavity 11 is prevented from suddenly dropping.

[0033] In the embodiment, the air outlet device is used for setting on the oil-gas separator.

[0034] As shown in Figure 1 and Figure 3 , the vent hole 14 is a plurality of vent holes, and the plurality of vent holes 14 are arranged at intervals around the central axis of the main structure 10.

At the same time, the above arrangement not only avoids the waste of energy and reduces the operation cost, but also improves the automation degree of the air outlet device and reduces the labor intensity of the workers.

[0036] In the embodiment, the temperature detection structure is a temperature sensor.

[0037] In the embodiment, the control structure 40 is an electronic controller, which is connected with the heating structure 30 through a relay and controls the opening and closing of the relay to control the heating structure 30.

[0038] Specifically, when the detection value of the temperature detection structure is lower than -10℃, the control structure 40 controls the relay to close to supply power to the heating structure 30, and the heating structure 30 opens; when the detection value of the temperature detection structure is higher than -10℃, the control structure 40 controls the relay to open to stop supplying power to the heating structure 30, and the heating structure 30 closes.

[0039] Specifically, the air outlet device further comprises an alarm structure and a camera structure. The alarm structure is used to send an alarm signal, and the alarm signal comprises at least one of a light signal and a sound signal. The camera structure is arranged on the air outlet part 13 to take pictures of the air outlet part 13. The control structure 40 is connected with the camera structure and the alarm structure, and the control structure 40 controls the opening of the alarm structure according to the shooting result of the camera structure.

[0040] In the embodiment, the camera structure is a high-definition camera.

[0041] In the embodiment, the alarm structure is one of a buzzer and a sound-light alarm.

[0042] Specifically, the thickness T of the heat preservation structure 20 satisfies: 4.8mm≤T≤5.2mm. In this way, the above setting makes the heat preservation structure 20 achieve the heat preservation function while reducing its own weight, realizing the lightweight design of the air outlet device.

[0044] In the embodiment, the vent hole 14 is a circular hole, and the diameter D of the vent hole 14 satisfies: 7.8mm≤D≤8.2mm. In this way, the above setting ensures that the gas can be discharged through the air outlet part 13, and also ensures that after the air outlet part 13 is blocked by ice, the gas can be discharged through the vent hole 14, ensuring the stability of the pressure of the crankcase. At the same time, the above setting ensures the air outlet function of the vent hole 14, while avoiding the waste of materials due to the too large diameter, improving the economy of the air outlet device; also avoiding the increase of the processing difficulty of the workers due to the too small diameter, improving the work efficiency of the workers.

[0045] In the embodiment, the diameter D of the vent hole 14 satisfies: D=8mm, so as to ensure that the diameter D of the vent hole 14 is more appropriate.

[0046] As shown in Figure 1 and Figure 2 , the heating structure 30 is arranged on the air outlet part 13, and the heating structure 30 is an electric heater. In this way, the heating structure 30 heats the air outlet part 13 to achieve the heating of the main body structure 10, thereby ensuring the smoothness of the gas discharge. At the same time, the heating structure 30 is arranged on the air outlet part 13 to accurately prevent the icing of the air outlet part 13, which improves the heating reliability of the heating structure 30 while avoiding the waste of energy, improving the economy of the air outlet device. At the same time, compared with the fuel heating method, the electric heater is not limited by the regional environment, improving the universality of the heating structure 30; on the other hand, the heating structure 30 does not need to frequently replace the heating medium, improving the economy and safety of the heating structure.

[0047] In the embodiment, the heat preservation structure 20 has a preset distance L1 between one end close to the air outlet 101 and the air outlet 101, and has a preset distance L2 between one end away from the air outlet 101 and the air outlet end of the air outlet part 13, and the preset distance L1 and the preset distance L2 satisfy: L1≤L2. In this way, the above setting can not only ensure that the gas is smoothly discharged from the air outlet cavity 21 to the outside, but also ensure the heat preservation function of the heat preservation structure 20. At the same time, the above setting can also provide installation space for the heating structure 30, and ensure the installation convenience of the heating structure 30. At the same time, the above setting can also reserve a certain distance between the heat preservation structure 20 and other components, so as to avoid the influence of other structures on the heat preservation structure 20, thereby prolonging the service life of the heat preservation structure 20.

[0048] Specifically, the preset distance L1 satisfies: 20mm≤L1≤50mm, and the preset distance L2 satisfies: 10mm≤L2≤20mm. In this way, the above setting ensures the smoothness of the gas discharged from the air outlet cavity 21 to the outside, and also ensures the heat preservation reliability of the heat preservation structure 20 on the main structure 10. At the same time, the above setting can also realize the installation smoothness of the heating structure 30, and improve the overall safety of the air outlet device. At the same time, the above setting also makes the distance between the heat preservation structure 20 and other components more reasonable, and further prolongs the service life of the heat preservation structure 20.

[0049] Specifically, the heat preservation structure 20 is a foamed rubber piece. In this way, the foamed rubber can not only effectively reduce heat loss and improve the heat preservation effect of the heat preservation structure 20, but also can reduce the weight of the heat preservation structure 20 and ensure the lightweight design of the air outlet device. At the same time, the foamed rubber also has elasticity, which ensures the impact resistance of the heat preservation structure 20, thereby ensuring the impact resistance of the air outlet device.

[0050] In the embodiment, the heat preservation structure 20 is one of a three-element ethylene-propylene foamed rubber and a butyronitrile foamed rubber.
