Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a gas-liquid separator. Background Technology

[0002] In the current field of waste gas treatment, to achieve the best separation efficiency, the design of the wire mesh demister inside the tank-type gas-liquid separator usually requires maintaining a face velocity of 2.5~3m / s, thereby determining the demister area and deriving a reasonable equipment diameter based on the processing air volume. However, in specific scenarios where space is limited, transportation conditions are harsh, or overall material costs need to be optimized, it is necessary to meet the above-mentioned wind velocity requirements while minimizing the equipment diameter. This constitutes an irreconcilable contradiction in traditional design concepts—efficient separation inevitably depends on sufficient flow area, while space constraints require a reduction in equipment size. To address this core pain point, this utility model proposes a gas-liquid separator that aims to break through the trade-off dilemma in traditional design and achieve a synergistic improvement in separation efficiency and space adaptability. Utility Model Content

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0021] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0022] Please see Figures 1 to 6This utility model provides a gas-liquid separator, including a feeding chamber 2 located on the lower side of a separation tank 1, a filter chamber 3 located inside the separation tank 1 above the feeding chamber 2, an air outlet 4 located on the upper side of the filter chamber 3, and a liquid outlet 5 located on the bottom side of the filter chamber 3. Gas filtered through the filter chamber 3 is discharged through the air outlet 4, while the filtered liquid is collected and discharged through the liquid outlet 5. Two sets of demister meshes are arranged vertically inside the filter chamber 3, including an upper demister mesh 6 and a lower demister mesh 7. The lower demister 7, upper demister 6, and lower demister 7 are arranged in a staggered manner. Compared with traditional single-layer wire mesh demisters, the staggered arrangement of the upper demister 6 and lower demister 7 results in a higher effective interception area for the same diameter separation tank 1. Furthermore, a sealing plate 8 is installed in the staggered space between the upper demister 6 and lower demister 7. The sealing plate 8 guides the gas-liquid mixture, allowing the mixed gas to more stably contact the entire area of ​​the upper demister 6, thus avoiding waste of filtration area.

[0023] The bottom of the diversion chamber 9 is threaded to the upper side of the feed chamber 2. The threaded connection ensures the airtightness of the feed chamber 2 and facilitates the subsequent disassembly of the diversion chamber 9. The upper side of the diversion chamber 9 extends into the filter chamber 3. Furthermore, a diversion air hole 10 is provided on the side wall of the diversion chamber 9 extending into the filter chamber 3. The diversion air hole 10 is used to deliver the gas in the diversion chamber 9 to the filter chamber 3 more evenly, thereby avoiding the gas from concentrating and impacting the upper demister 6 or the lower demister 7 in a localized area, and avoiding the problem of insufficient filtration of the mixed gas.

[0024] A primary filter 11 is installed inside the diversion chamber 9. The primary filter 11 is arranged along the inner wall of the diversion chamber 9. The primary filter 11 can filter out large particles of impurities. Multiple sets of waste liquid outlets 12 are provided at the bottom of the diversion chamber 9, which can conveniently discharge the waste liquid filtered by the primary filter 11 in a timely manner and avoid accumulation in the diversion chamber 9.

[0025] The top of the diversion chamber 9 is provided with a conical guide shroud 13, which can guide the falling liquid. The opening end of the guide shroud 13 faces downward, and the bottom edge of the guide shroud 13 extends out of the side wall of the diversion chamber 9 to prevent the liquid filtered on the upper demisting net 6 and the lower demisting net 7 from falling into the diversion chamber 9.

[0026] The side wall of the filter chamber 3 is provided with a demisting mesh installation hole 14, which facilitates the installation of the upper demisting mesh 6 and the lower demisting mesh 7. The ends of the upper demisting mesh 6 and the lower demisting mesh 7 on the side away from the demisting mesh installation hole are spaced apart from the inner wall of the filter chamber 3, which can avoid the gas accumulation caused by the upper demisting mesh 6 and the lower demisting mesh 7 filtering the gas in the full coverage state, and provide a slow flow space for the gas in the filter chamber 3.

[0027] The sealing plate 8 is located between the ends of the upper demister 6 and the lower demister 7 on the side away from the demister mounting hole. The sealing plate 8 is inclined at a 45° angle to prevent gas from accumulating at the angle between the sealing plate 8 and the upper and lower demister 6 and the lower demister 7, thus ensuring the effectiveness of the upper and lower demister 6 in filtering the gas.

[0028] A return pipe 15 is installed on the side wall of the filter chamber 3 below the lower demisting net 7. The return pipe 15 is connected to the feed chamber 2. When the raw material intake air volume at the feed chamber 2 is too large, the return pipe 15 is used to return the gas that cannot be filtered in time to the feed chamber 2 to avoid gas accumulation and affect the filtration effect.

[0029] A manhole 16 is provided on the separation tank 1 above the upper demisting net 6 to observe the demisting status inside the separation tank 1. During routine inspections, workers can observe the status of the wire mesh demister through the maintenance platform and the manhole 16.

[0030] The diversion vents 10 are evenly distributed on the side wall of the diversion chamber 9 to ensure the uniformity of gas flow when it exits the diversion chamber 9.

[0031] The upper demisting mesh 6 and lower demisting mesh 7 of this utility model, arranged in a layered and staggered manner, have a higher effective interception area under the same diameter separation tank 1 compared to traditional single-layer wire mesh demisters. Furthermore, a sealing plate 8 is provided in the staggered space between the upper demisting mesh 6 and the lower demisting mesh 7. The sealing plate 8 guides the gas-liquid mixture, allowing the mixed gas to more stably contact the entire area of ​​the upper demisting mesh 6, thus avoiding waste of filtration area. The gas diversion holes 10 are used to more evenly deliver the gas in the diversion chamber 9 to the filter chamber 3, thereby preventing the gas from concentrating and impacting local positions of the upper demisting mesh 6 or the lower demisting mesh 7, and avoiding the problem of insufficient filtration of the mixed gas.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
