Description

Technical Field

[0001] This utility model relates to a novel gas-liquid separator, belonging to the field of gas-liquid separation technology. Background Technology

[0002] Air compressors typically draw in air containing moisture. This moisture significantly increases the pressure dew point after compression. To prevent moisture from precipitating out, the compressed air is usually kept at a relatively high temperature. However, according to national standards, the compressed air must pass through an aftercooler to lower its temperature before exiting the compressor (the requirement is ambient temperature +12 to 15°C). This process causes some moisture to precipitate out of the compressed air. To remove this moisture and minimize the moisture content of the compressed air, an air-water separator is essential.

[0003] The main function of a gas-liquid separator is to remove moisture entrained in gas and improve its dryness. Based on differences in separation mechanisms, gas-liquid separators are mainly classified into the following types: baffle type, cyclone type, and adsorption type. Baffle-type gas-liquid separators use multiple baffles arranged in an alternating pattern, causing the airflow to change direction multiple times internally. Liquid droplets accumulate on the baffle surfaces and fall into the drain outlet. Cyclone-type gas-liquid separators use spiral blades or tangential inlets to create a high-speed rotating airflow, using centrifugal force to throw droplets against the inner wall of the casing and discharge them. Adsorption-type gas-liquid separators have an internal water filter assembly; droplets are adsorbed and separated by the filter assembly.

[0004] All of the above separation methods involve significant energy loss. For air compressors, energy loss means that the compressor must overcome greater resistance to maintain rated pressure, thus increasing compression power consumption. Utility Model Content

[0005] This invention addresses the aforementioned shortcomings of existing technologies by proposing a novel gas-water separator that reduces energy loss during the gas-water separation process, decreases pressure drop, and improves the energy efficiency of the air compressor.

[0006] This utility model relates to a novel gas-water separator, comprising:

[0007] Import segment;

[0008] Export section;

[0009] The water removal section is used to connect the inlet section and the outlet section; the water removal section is U-shaped and has a drain outlet at the bottom of the U-shape;

[0010] The height-to-diameter ratio H / DN of the dewatering section is ≥3.5, which allows for efficient cooling of the compressed air, thereby removing as much water as possible and discharging it from the bottom.

[0011] In some preferred embodiments, the inlet section and the dewatering section are smoothly transitioned by an arc-shaped pipe, and the inlet section has an expansion section; when compressed air passes through the expansion section, a small amount of the water it contains can be separated out.

[0012] In some preferred embodiments, the outlet section and the dewatering section are smoothly transitioned by an arc-shaped pipe, and the outlet section has a contraction section; when compressed air passes through the contraction section, a small amount of its contained moisture can be further separated.

[0013] Compared with the prior art, the present invention has the following technical effects:

[0014] 1. The U-shaped dewatering section with specific parameters enables efficient cooling of high-temperature and high-pressure compressed air as it passes through, removing as much water as possible. The removed water can be discharged from the bottom drain, reducing the water content of the compressed air.

[0015] 2. No baffles, blades, adsorption materials or other gas-liquid separation components are required, which avoids a large loss of gas energy (i.e. pressure drop) during the gas-liquid separation process and improves the energy efficiency of the air compressor. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly defined, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1 As shown, this novel embodiment relates to a novel gas-water separator, comprising:

[0021] Inlet section 100; Inlet section 100 is connected to the exhaust port of the air compressor via a flange;

[0022] Outlet section 200; Outlet section 200 is connected to the gas storage tank via a flange;

[0023] The water removal section 300 is used to connect the inlet section 100 and the outlet section 200; the water removal section 300 is U-shaped and has a drain outlet 400 at the bottom.

[0024] The height-to-diameter ratio (H / DN) of the dewatering section 300 is ≥3.5, which allows for efficient cooling of the high-temperature, high-pressure compressed air, thereby removing as much water as possible and discharging it from the bottom drain outlet 400. For example, the value of H / DN can be 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, etc.

[0025] In some preferred embodiments, the inlet section 100 and the dewatering section 300 are smoothly transitioned by an arc-shaped pipe, and the inlet section 100 has an expansion section 101; more preferably, the expansion section 101 is frustum-shaped; more preferably, the diameter ratio of the expansion section D1 / d1 ≥ 1.3; when compressed air passes through the expansion section 101, a small amount of its contained moisture can be separated out. For example, the value of D1 / d1 can be 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, etc.

[0026] In some preferred embodiments, the outlet section 200 and the dewatering section 300 are smoothly transitioned by an arc-shaped pipe, and the outlet section 200 has a contraction section 201; more preferably, the contraction section 201 is frustum-shaped; more preferably, the diameter ratio of the contraction section D2 / d2 ≥ 1.3; when compressed air passes through the contraction section 201, a small amount of moisture contained therein can be further separated. For example, the value of D2 / d2 can be 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, etc.

[0027] This invention utilizes a U-shaped dewatering section 300 with specific parameters to efficiently cool high-temperature, high-pressure compressed air as it passes through, removing as much moisture as possible. The removed moisture is promptly discharged from the bottom drain port 400, reducing the water content of the compressed air. Furthermore, it eliminates the need for baffles, blades, adsorption materials, or other gas-water separation components, avoiding significant energy loss during gas-water separation and improving the energy efficiency of the air compressor.

[0028] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
