Description

Technical Field

[0001] This utility model relates to the field of gas-liquid filtration equipment technology, and in particular to an integrated gas-liquid separation filter. Background Technology

[0002] In the compressed air purification industry, traditional gas-liquid separators and compressed air precision filters are supplied separately. Traditional compressed air precision filters use filter elements to filter water, oil, and solid particles from compressed air. Both products are connected to the gas delivery pipeline via pipes, increasing the difficulty and cost of pipeline construction, as well as increasing pipeline pressure loss.

[0003] Therefore, there is an urgent need for an integrated gas-liquid separator filter that integrates a gas-liquid separator with a filter, effectively reducing pipeline connections and installation space, while also reducing external installation costs. Utility Model Content

[0004] The purpose of this invention is to provide an integrated gas-liquid separation filter that solves the technical problems of increased pipeline construction difficulty and cost, and increased pipeline pressure loss in existing technologies. The various technical effects of the preferred technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an integrated gas-liquid separation filter, comprising:

[0007] Lower housing;

[0008] A separator cylinder is installed on the inner top of the lower housing, and the separator cylinder is in communication with compressed air between itself and the inner wall of the lower housing.

[0009] An upper housing, which is mounted above the lower housing;

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] refer to Figure 1-4 A specific embodiment of this utility model provides an integrated gas-liquid separation filter, comprising:

[0036] Lower housing 2;

[0037] The separator 4 is installed on the top inner side of the lower housing 2, and the separator 4 is in communication with the inner wall of the lower housing 2 and compressed air.

[0038] Upper housing 1, which is mounted on top of lower housing 2;

[0039] Filter element 8 is installed inside the upper housing 1, and the air inlet side of filter element 8 is connected to the separator cylinder 4.

[0040] Traditional compressed air precision filters use filter elements to filter water, oil, and solid particles from compressed air. These two products are connected to the gas delivery pipeline via pipes, increasing the difficulty and cost of pipeline construction, as well as increasing pipeline pressure loss. In this application, the lower housing 2 and the separator 4 form a gas-liquid separator 14 for separating gas and liquid, and the upper housing 1 and the filter element 8 form a filter 15. The filter 15 is installed above the gas-liquid separator 14. Compressed air passes sequentially through the gas-liquid separator 14 and the filter 15, moving from bottom to top before being discharged. Overall, this application integrates the gas-liquid separator 14 and the filter 15, effectively reducing pipeline connections and installation space, while also reducing external installation costs.

[0041] Further optimizations to the plan include:

[0042] The second channel 7 is disposed inside the upper housing 1 and is connected between the air inlet side of the filter element 8 and the top of the separator cylinder 4. The second channel 7 is separated from the cavity where the filter element 8 is located.

[0043] Wire mesh 6 is installed at the connection between the second channel 7 and the separator cylinder 4.

[0044] After the compressed air passes through the separator 4, it undergoes initial gas-liquid separation. A small amount of residual condensate is filtered out by the wire mesh 6, dripping to the bottom of the lower housing 2. The compressed air then enters the second channel 7, and is subsequently filtered by the filter element 8 before being discharged. The wire mesh 6 performs a secondary interception of water mist and air bubbles in the air.

[0045] Further optimizations to the plan include:

[0046] The air inlet 5 is located on the outer side wall of the lower housing 2 and is connected to the bottom of the partition cylinder 4. The air intake direction of the air inlet 5 is set along the tangential direction of the lower housing 2.

[0047] Compressed air enters the lower housing 2 through the air inlet 5, flowing tangentially and rapidly forming a cyclone separator along the periphery of the separator 4. Due to gravity, the gas enters from the bottom of the separator 4 and rises upwards. The separated liquid condensate falls along the inner wall of the lower housing 2 to the bottom of the lower housing 2 and is discharged through an automatic drain. The air inlet 5 employs a variable diameter structure to alter the gas flow rate, ensuring the compressed air enters the lower housing 2 tangentially, which facilitates rapid cyclone separation.

[0048] Further optimizations to the plan include:

[0049] The first channel 13 is formed between the separator cylinder 4 and the inner wall of the lower housing 2, and the first channel 13 is connected to the air inlet 5.

[0050] Compressed air enters the lower housing 2 through the air inlet 5, that is, it directly enters the first channel 13. The compressed air quickly forms a cyclone separation effect in the first channel 13.

[0051] Further optimizations to the plan include:

[0052] Water collection shell 3 is installed at the bottom of the lower shell 2 and is connected to the interior of the lower shell 2.

[0053] The separated liquid condensate falls into the water collection shell 3 and is discharged uniformly.

[0054] Further optimizations to the plan include:

[0055] The umbrella-shaped plate 10 is located at the bottom of the lower housing 2 and is installed on the water collection shell 3. A gap is provided between the edge of the umbrella-shaped plate 10 and the water collection shell 3.

[0056] The umbrella-shaped plate 10 mainly serves a separating function; when the liquid condensate flows into the water collection shell 3, the liquid surface is not affected by the gas separated by the cyclone, and the mist is carried into the upper filter 15 by the compressed gas, which greatly improves the gas-liquid separation efficiency.

[0057] Further optimizations to the plan include:

[0058] The first sewage outlet 11 is located at the bottom of the water collection shell 3;

[0059] The second drain outlet 12 is located on the side wall of the lower housing 2 and is connected to the drain outlet at the bottom of the filter element 8.

[0060] The condensate filtered by filter element 8 drips continuously and is discharged from the second drain port 12. The condensate in the water collection shell 3 is discharged through the first drain port 11.

[0061] Further optimizations to the plan include:

[0062] Exhaust port 9 is located on the side wall of the upper housing 1 and is connected to the filter side of the filter element 8.

[0063] Compressed air that has passed through the cyclone separation of the separator 4, the wire mesh 6, and the filter element 8 is discharged from the exhaust port 9.
