This will not only affect the normal operation of the separator, but may also cause damage to the equipment and even cause safety accidents.
[0004] Therefore, it is urgent to propose a new type of separator to deal with the situation where the liquid content of the upstream gas is unstable. Utility Model Content

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0031] like Figure 1 As shown, the utility model provides a compressor inlet pre-separator, including: a separation cylinder 10 and a horizontal filter 20, the horizontal filter 20 is arranged in the middle of the separation cylinder 10, a first air inlet 21, a first liquid discharge port 22 and a first air outlet 23 are provided on the horizontal filter 20, the horizontal filter 20 is connected with the separation cylinder 10 through the first air outlet 23, and a filter element 27 is arranged inside the horizontal filter 20; the horizontal filter 20 is used to perform a first-stage gas-liquid separation on the upstream air, and the separation cylinder 10 is used to perform a second-stage gas-liquid separation on the upstream air. When the utility model is in use, the upstream air enters the horizontal filter 20 from the first air inlet 21, and after the first-stage gas-liquid separation is performed by the filter element 27, the upstream air enters the separation cylinder 10 through the first air outlet 23, and the separated liquid is discharged from the horizontal filter 20 through the first liquid discharge port 22. After the upstream air enters the separation cylinder 10, the second-stage gas-liquid separation is performed by gravity collision. The utility model solves the problem of unstable liquid content in upstream gas. When the liquid content is large, the water can be automatically drained, and when the liquid content is small, the air can be automatically exhausted. The separation efficiency and separation accuracy are very high, and the gas-liquid two phases can be separated and then pressurized and mixed again.
[0032] As an optimization solution of the utility model, Figure 2 and Figure 3 As shown, the horizontal filter 20 is a cylindrical structure, the first air inlet 21 is arranged at the top of the horizontal filter 20, the first liquid discharge port 22 is arranged at the bottom of the horizontal filter 20, and a ring plate 24 is arranged at one end of the horizontal filter 20, and a plurality of first air outlets 23 are opened on the ring plate 24 and communicated with the separation cylinder 10. Preferably, the first liquid discharge port 22 can be designed as a structure that is bent and extended to the side by an elbow and a reinforcing pipe, so as to facilitate the laying of pipelines during use. Preferably, three first air outlets 23 can be opened on the ring plate 24, and the gas filtered by the filter element 27 enters the separation cylinder 10 from the first air outlet 23.
[0033] As an optimization solution of the utility model, Figure 2 and Figure 3As shown, the other end of the horizontal filter 20 is a flange structure 25, and a liquid spray pipe 26 is also arranged in the horizontal filter 20. One end of the liquid spray pipe 26 passes through the center of the flange structure 25, and the other end of the liquid spray pipe 26 passes through the center of the ring plate 24. Multiple rows of through holes 261 are evenly spaced on the liquid spray pipe 26, and the liquid spray pipe 26 is used to spray liquid during backwashing. Preferably, one end of the liquid spray pipe 26 that passes through the center of the flange structure 25 is a backwash liquid inlet. During backwashing, water is injected into the horizontal filter 20 from the backwash liquid inlet to backwash the filter element 27. Preferably, the center of the ring plate 24 has a fixed hole that matches the liquid spray pipe 26, and the other end of the liquid spray pipe 26 is fixed through the fixed hole. It should be noted that the gas enters the horizontal filter 20 from the first air inlet 21 at the top, and the gas passes through the filter element 27 from the outside of the filter element 27 to perform gas-liquid separation, so the dirt is embedded from the outside to the inside. Therefore, water is injected into the spray pipe 26, and the backwash liquid is flushed from the inner side of the filter element 27 through the multiple rows of through holes 261 evenly spaced on the spray pipe 26, which can effectively flush away the dirt from the inside to the outside. The backwash liquid after flushing is discharged through the first drain port 22 or enters the separation cylinder 10 and then discharged.
[0034] As an optimization solution of the utility model, Figure 2 As shown, the filter element 27 is a cylindrical ring net structure, and the filter element 27 is clamped and arranged on the flange structure 25 and the clamping groove 271 of the ring plate 24. Preferably, the filter element 27 can be a glass fiber filter element, a polyester fiber filter element, a ceramic filter element, a stainless steel filter element or a polyamide filter element. Preferably, by disassembling the flange structure 25, the filter element 27 can be replaced regularly and the inside of the horizontal filter 20 can be cleaned.
[0035] As an optimization solution of the utility model, Figure 1 As shown, the bottom of the separation cylinder 10 is provided with a second liquid discharge port 11 and a sewage discharge port 12. Preferably, the second liquid discharge port 11 and the sewage discharge port 12 can also be designed as a structure that is bent and extended to the side by an elbow and a reinforcing pipe, so that it is convenient to lay the pipeline during use. Preferably, the second liquid discharge port 11 can discharge the separated liquid in the separation cylinder 10 in time, and the sewage discharge port 12 is used to regularly discharge the dirt and impurities in the separation cylinder 10.
[0036] As an optimization solution of the utility model, Figure 1 As shown, the outer wall of the separation cylinder 10 is provided with a first liquid level gauge port 13 and a second liquid level gauge port 14 at intervals, and the first liquid level gauge port 13 and the second liquid level gauge port 14 are used to measure the liquid level height of the separation cylinder 10. Through the synergistic effect of the first liquid level gauge port 13 and the second liquid level gauge port 14, it can be ensured that the liquid level gauge in the vertical separator can accurately reflect the liquid level height and maintain the stability of the measurement during the measurement process. This is of great significance for ensuring the smooth progress of the industrial production process and the quality of the product.
[0037] As an optimization solution of the utility model, Figure 1 As shown, a second gas outlet 15 is also provided on the outer wall of the separation cylinder 10 and is in height opposite to the first liquid level gauge port 13. Preferably, the second gas outlet 15 is used to output gas with relatively low gas quality, which can be applied to different customer needs.
[0038] As an optimization solution of the utility model, Figure 1 As shown, two mutually opposing water baffles can also be designed under the second gas outlet 15, and the water baffles can effectively block liquid droplets or liquid mist in the gas to prevent them from directly entering the gas phase space or the gas outlet. In the gas-liquid separation process, due to the different densities of liquid and gas, the liquid tends to flow downward under the action of gravity. The presence of the water baffle can ensure that these liquids are blocked during the flow process and flow into the liquid phase collection area, thereby improving the efficiency of gas-liquid separation. The water baffle can also help stabilize the liquid level in the vertical separator. In the gas-liquid separation process, the fluctuation of the liquid level may affect the separation effect. The water baffle can limit the flow rate of the liquid, reduce the fluctuation of the liquid level, and keep the liquid level within a relatively stable range, thereby ensuring the stability and reliability of the separation process. In the gas-liquid separation process, the gas may entrain some fine droplets or liquid mist. If these droplets or liquid mist flow out of the separator with the gas, it may have an adverse effect on subsequent equipment or processes. The presence of the water baffle can effectively block these droplets or liquid mist to prevent them from flowing out with the gas, thereby ensuring the purity and quality of the gas.
[0039] As an optimization solution of the utility model, Figure 1 As shown, a third gas outlet 16 is provided at the top of the separation cylinder 10, and a wire mesh demister 17 is also provided between the third gas outlet 16 and the second gas outlet 15 in the separation cylinder 10, and the wire mesh demister 17 is used to perform a third-level gas-liquid separation on the upstream gas. Preferably, the wire mesh demister 17 uses its special wire mesh structure to allow the liquid droplets therein to be captured on the wire mesh due to inertia when the gas passes through. Since the wire mesh demister 17 has a high surface area and a small pore size, it can capture and remove liquid droplets with a diameter greater than 3-5 microns, and its capture efficiency can reach 98%-99.8%. In the utility model, the wire mesh demister 17 is installed between the third gas outlet 16 and the second gas outlet 15, so that the third gas outlet 16 can output gas with relatively high gas quality, which can be applied to different customer needs.
[0040] At the same time, the wire mesh demister 17 can ensure that the gas can fully carry out gas-liquid separation before leaving the separator. In this way, the wire mesh demister 17 can effectively prevent the droplets in the gas from corroding and blocking the equipment and pipelines, and also help to improve the operating efficiency and safety of the equipment.
[0041] As an optimization solution of the utility model, Figure 1 As shown, a liquid level switch port 18 is also provided on the outer wall of the separation cylinder 10 and is highly opposite to the first liquid level gauge port 13. Preferably, when the first liquid level gauge port 13 and the second liquid level gauge port 14 detect that there is too much liquid stored in the separation cylinder 10, emergency pressure relief and drainage can be performed through the liquid level switch port 18 to prevent equipment damage.
[0042] As an optimization solution of the utility model, Figure 1 As shown, a second air inlet 19 is provided at the lower part of the separation cylinder 10. Preferably, the utility model can be applied to different customer needs. When the liquid content of the upstream gas is stable, the upstream gas can also be directly introduced into the separation cylinder 10 through the second air inlet 19 for gas-liquid separation.
[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
