Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separation collectors, in particular to a novel compressed air condensate oil-water separation collector. Background Art

[0002] Compressed air condensate contains different levels of lubricating oil that harms the environment. Environmental protection regulations require that most of the lubricating oil must be removed before the condensate is discharged into the sewer. For this reason, factory air compressor systems are now equipped with oil-water separators.

[0003] At present, the oil-water separators on the market mainly use gravity separation and then secondary filtration through activated carbon bags or polypropylene filter elements before discharge. However, considering the convenience of product sales and installation, the product size is relatively small. Due to the limitation of product size, it is difficult to collect waste oil in actual use. The collected waste oil contains more water, which causes the product to need to be replaced regularly and the cost is relatively high. Utility Model Content

[0004] The utility model aims to solve the shortcomings existing in the prior art, and comprises: a water inlet pipe; a pressure reducing pipe, one end of which is connected to the water inlet pipe, and the other end of which is connected to a liquid storage pipe; an oil-water separation pipe, which is connected to one end of the liquid storage pipe, and the oil-water separation pipe is formed by a five-stage separation channel; a clamping pipe, which is connected to the water outlet end of the oil-water separation pipe; and a waste oil collecting pipe, whose oil inlet end is connected to the oil-water separation pipe.

[0005] As a further description of the above technical solution: an air exhaust pipe is provided at one end of the liquid storage pipe close to the pressure reducing pipe.

[0006] As a further description of the above technical solution: a flow limiting tube is arranged at one end of the liquid storage tube close to the oil-water separation tube, and an overflow tube is arranged on the flow limiting tube.

[0007] As a further description of the above technical solution: a first maintenance drain valve is arranged on the clamp pipe, a condensate drain valve is arranged at the water outlet end of the clamp pipe, and a second maintenance drain valve is arranged at one end of the oil-water separation pipe.

[0008] As a further description of the above technical solution: the clamp tube is connected to one end of the waste oil collection pipe, and a secondary separation drain valve is provided between the clamp tube and the waste oil collection pipe.

[0009] As a further description of the above technical solution: a waste oil discharge valve is arranged below the waste oil collection pipe.

[0010] As a further description of the above technical solution: the oil-water separation pipe, clamp pipe and waste oil collection pipe are made of PVC or PE material.

[0011] The above technical solution has the following advantages or beneficial effects:

[0012] 1. The utility model maximizes the effect of gravity separation by adopting a gravity separation main body design that is several times higher than that of a traditional oil-water separator. There is no filtering device, and the oil-water separation effect is continuous and stable. Compared with traditional oil-water separators, it does not require maintenance and is more reliable.

[0013] 2. Because the liquid area of ​​the oil-water separation body of this oil-water separator is designed to be very small, waste oil is easy to form a thicker oil layer, and it is particularly easy to collect waste oil into the waste oil collection pipe. The waste oil collection pipe also has a secondary oil-water separation function. By operating the drain valve, secondary separation drain valve, waste oil discharge valve and condensate drain valve, waste oil collection, waste oil purification and waste oil recovery can be completed. The operation process is simple and clean.

[0014] 3. The inlet pressure reducing pipe and liquid storage pipe of the oil-water separator can be installed on the upper part of the machine room without occupying the ground space. The large volume can withstand the impact of short-term large flow of condensate without causing leakage of condensate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-2 As shown, a novel compressed air condensate oil-water separation collector of the utility model comprises: a water inlet pipe 1; a pressure reducing pipe 2, one end of the pressure reducing pipe 2 is connected to the water inlet pipe 1, and the other end of the pressure reducing pipe 2 is connected to the liquid storage pipe 4; an oil-water separation pipe 6, the oil-water separation pipe 6 is connected to one end of the liquid storage pipe 4; a clamp pipe 7, the clamp pipe 7 is connected to the water outlet end of the oil-water separation pipe 6; a waste oil collection pipe 8, the oil inlet end of the waste oil collection pipe 8 is connected to the oil-water separation pipe 6, a waste oil discharge valve 11 is arranged below the waste oil collection pipe 8, and an air discharge pipe 3 is arranged at one end of the liquid storage pipe 4 close to the pressure reducing pipe 2.

[0023] In this embodiment, the mixture of compressed air condensed water and compressed air gas enters the pressure reducing pipe 2 through the water inlet pipe 1, the compressed air is discharged through the air discharge pipe 3, and the condensed water enters the liquid storage pipe 4 for storage. After a certain amount of storage, it will enter the oil-water separation pipe 6. The lubricating waste oil in the condensed water will float to the top of the oil-water separation pipe 6, and the water will be discharged according to the pressure reducing pipe 2. Figure 1 The flow direction shown is that after passing through the five-level water pipe, it flows out from the clamp pipe 7, passes through the condensate drain valve 12, and then flows to the municipal sewage pipe or the oil-water filter for more environmentally friendly treatment; the oil layer on the oil-water separation pipe 6 gradually thickens under the continuous oil-water separation work. Because the specific gravity of oil is small, the total height of water and oil also gradually increases. Finally, the oil layer height reaches the waste oil overflow port of each water pipe and enters the waste oil collection pipe 8. When the waste oil collection pipe is full of waste oil, the waste oil discharge valve 11 is opened to discharge it into the waste oil barrel and take it away for hazardous waste treatment.

[0024] By adopting a gravity separation body designed with a height several times that of a traditional oil-water separator, the effect of gravity separation is maximized. There is no filtering device, and the oil-water separation effect is continuous and stable. Compared with traditional oil-water separators, it does not require maintenance and is more reliable. Because the liquid area of ​​the oil-water separation body of the oil-water separator is designed to be very small, waste oil is easy to form a thicker oil layer, and it is particularly easy to collect waste oil into the waste oil collection pipe, and the waste oil collection pipe has a secondary oil-water separation function. Only by operating the drain valve, the secondary separation drain valve 10, the waste oil discharge valve 11 and the condensate drain valve 12 can the waste oil collection, waste oil purification and waste oil recovery be completed, and the operation process is simple and clean. The inlet pressure reducing pipe 2 and the liquid storage pipe 4 of the oil-water separator can be installed on the upper part of the machine room without occupying the ground space. The large volume can withstand the impact of short-term large-flow condensate without causing condensate leakage.

[0025] like Figure 1 and Figure 2 As shown, specifically, a limiting flow tube 41 is provided at one end of the liquid storage tube 4 near the oil-water separation tube 6, and an overflow tube 5 is provided on the limiting flow tube 41; when the condensate in the liquid storage tube 4 passes through the limiting flow tube 41, it will be buffered, and a larger overflow tube 5 is connected in parallel above the limiting flow tube 41. When the condensate increases abnormally, the water in the liquid storage tube 4 will slowly and steadily flow into the oil-water separation tube 6 composed of five water pipes for five-stage gravity separation.

[0026] like Figure 1 and Figure 2 As shown, specifically, a first maintenance drain valve 9 is provided on the clamp tube 7, a condensate drain valve 12 is provided at the water outlet end of the clamp tube 7, and a second maintenance drain valve 13 is provided at one end of the oil-water separation tube 6; the first maintenance drain valve 9 and the second maintenance drain valve 13 are mainly used during maintenance, firstly, the first maintenance drain valve 9 is opened to discharge the water in the oil-water separation tube 6 to a lower liquid level, and then the remaining oil and water are drained through the second maintenance drain valve 13, so as to facilitate maintenance and clean the dirt inside the pipe.

[0027] like Figure 1 and Figure 2 As shown, specifically, the clamp tube 7 is connected to one end of the waste oil collecting tube 8, and a secondary separation drain valve 10 is provided between the clamp tube 7 and the waste oil collecting tube 8; when the amount of waste oil in the oil-water separation tube 6 is small, the liquid level of the oil-water separation tube 6 can be actively raised by closing the condensed water drain valve 12 to actively collect the waste oil in the waste oil collecting tube 8; if the waste oil contains a lot of water, the waste oil in the waste oil collecting tube 8 can be left to stand for a few days to allow the oil and water to be secondary separated, and the water at the bottom is discharged by opening the secondary separation drain valve 10, and what remains in the waste oil collecting tube 8 is pure waste oil, thereby reducing the amount of waste oil generated.

[0028] like Figure 1 and Figure 2As shown, specifically, the oil-water separation pipe 6, the clamping pipe 7 and the waste oil collection pipe 8 are made of PVC or PE material. The use of transparent PVC or PE pipes can observe the liquid level and the quality of the waste oil.

[0029] Working principle: The gravity separation effect is maximized by adopting a gravity separation body designed to be several times higher than that of traditional oil-water separators. There is no filtering device, and the oil-water separation effect is continuous and stable. Compared with traditional oil-water separators, it does not require maintenance and is more reliable. Because the liquid area of ​​the oil-water separation body of this oil-water separator is designed to be very small, waste oil is easy to form a thicker oil layer, and it is particularly easy to collect waste oil into the waste oil collection pipe, and the waste oil collection pipe also has a secondary oil-water separation function. Only by operating the drain valve, the secondary separation drain valve 10, the waste oil discharge valve 11 and the condensate drain valve 12 can the waste oil collection, waste oil purification and waste oil recovery be completed, and the operation process is simple and clean. The inlet pressure reducing pipe 2 and the liquid storage pipe 4 of the oil-water separator can be installed on the upper part of the machine room without occupying the ground space. The large volume can withstand the impact of short-term large-flow condensate without causing condensate leakage.
