A filtration-type gas-liquid separator

Abstract

This utility model discloses a filter-type gas-liquid separator, including a separator cylinder. An air jet guiding mechanism is fixedly installed inside the separator cylinder, and an air jet deflector mechanism is installed below the air jet guiding mechanism. The air jet deflector mechanism includes a fixed seat fixedly connected to the inner wall of the separator cylinder, and an outer deflector plate is screwed to the end of the fixed seat. An inner deflector plate is fixedly installed inside the outer deflector plate. An air inlet pipe is installed directly above the air jet deflector mechanism, and a filter mechanism is fixedly installed on the upper inside of the separator cylinder. This filter-type gas-liquid separator, through the pre-separation design achieved by the air jet guiding mechanism and the air jet deflector mechanism, can separate a large number of liquid droplets before the air jet enters the filter mechanism for final filtration. This effectively prevents the droplets from quickly filling the pores of the filter medium, thereby significantly extending the service life of the filter medium in the filter mechanism and reducing maintenance costs and downtime associated with frequent filter medium replacement or cleaning.

Description

Technical Field

[0001] This utility model relates to the field of separators, specifically a filter-type gas-liquid separator. Background Technology

[0002] Filter-type gas-liquid separators are core devices in industrial fluid handling used to separate gases and liquids (or tiny droplets). Their core principle is to force liquid particles in the gas-liquid mixture to be captured through a combination of "filter media interception" and "auxiliary separation mechanisms," ultimately achieving efficient separation of the two phases. When the gas-liquid mixture passes through a porous filter media (such as metal mesh, fiber felt, or ceramic filter element), liquid particles are trapped because their size is larger than the pores of the filter media or because they are "adsorbed onto the media surface," while the gas flows out through the pores. The core function of the filtration mechanism is to intercept tiny droplets (typically 1-50 μm), and its carrying capacity (the amount of liquid that can be retained per unit time) has a design upper limit. If the gas stream is not pre-separated (skipping gravity, centrifugation, or other pretreatment stages), a large number of medium to large droplets (50-200 μm or even millimeter-sized) will directly flow into the filter media.

[0003] When a filter-type gas-liquid separator is in use, the gas jet containing liquid impacts the filtration mechanism all at once. The gas jet does not undergo preliminary gas-liquid separation and relies entirely on the filtration mechanism for filtration. Medium and large liquid droplets will quickly fill the pores of the filter medium (such as the fiber gaps of fiber felt or the mesh of metal mesh), forming a "liquid film blockage". Subsequent airflow will have difficulty penetrating, and even tiny droplets cannot be effectively intercepted, resulting in "excessive liquid content" in the outlet gas. The separation efficiency will plummet to below 50% or even fail completely. Utility Model Content

[0004] The purpose of this invention is to provide a filter-type gas-liquid separator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a filter-type gas-liquid separator is provided, comprising a separator cylinder. An air jet guiding mechanism is fixedly installed inside the separator cylinder, and an air jet deflector mechanism is installed on the lower side of the air jet guiding mechanism. The air jet deflector mechanism includes a fixed seat fixedly connected to the inner wall of the separator cylinder, and an outer deflector plate is screwed to the end of the fixed seat. Meanwhile, an inner deflector plate is fixedly installed on the inner side of the outer deflector plate. An air inlet pipe is installed directly above the air jet deflector mechanism, and a filter mechanism is fixedly installed on the upper side of the inside of the separator cylinder.

[0006] Furthermore, a gas release hopper is fixedly provided at the upper end of the separator cylinder, and a liquid collection hopper is fixedly provided at the lower end of the separator cylinder. Both the liquid collection hopper and the gas release hopper are conical.

[0007] Furthermore, the air jet guiding mechanism includes an air inlet pipe, an air tank, an overflow plate, an overflow pipe, and a support base. Three sets of support bases are equidistantly installed at the bottom of the overflow plate, and the ends of the three sets of support bases are all fixed to the inner circumferential wall of the separator cylinder.

[0008] Furthermore, the overflow plate is equipped with an outer exhaust channel and an inner exhaust channel, with the bottom of the outer exhaust channel facing the outer deflector plate and the bottom of the inner exhaust channel facing the inner deflector plate.

[0009] Furthermore, both the outer and inner exhaust channels are composed of multiple sets of overflow pipes that are equidistantly distributed, with the upper end face of the overflow pipe passing through the overflow plate.

[0010] Furthermore, the overflow plate is fixedly installed at the bottom of the gas tank, and an air inlet pipe is fixedly installed at the upper end of the gas tank, and the air inlet pipe is "L" shaped.

[0011] Furthermore, the cross-sections of both the outer and inner baffle plates are V-shaped, and a V-shaped flow channel is formed between the outer and inner baffle plates. At the same time, a drain hole is provided at the bottom of the V-shaped flow channel.

[0012] Furthermore, the gas beam guiding mechanism and the gas beam deflector are distributed in parallel, and the gas beam guiding mechanism and the gas beam deflector are combined together to form a gas-liquid pre-separation mechanism for the gas beam.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This solution allows the airflow to uniformly collide with the outer and inner baffles on the surface of the air jet baffle mechanism. The heavier components in the air jet remain on the air jet baffle mechanism and enter the liquid collection hopper for collection through the leaks on the air jet baffle mechanism. At the same time, the lighter components move upward and are filtered by the filtration mechanism before being discharged from the gas release hopper. Before the air jet is separated into gas and liquid by the filtration mechanism, it can be pre-separated by the air jet guide mechanism and the air jet baffle mechanism to prevent droplets from quickly filling the pores of the filter medium, thereby improving the filtration efficiency and effect of the filtration mechanism.

[0015] 2. This solution employs a pre-separation design through the cooperation of an air jet guiding mechanism and an air jet deflector mechanism. This design can separate a large number of droplets before the air jet enters the filtration mechanism for final filtration, effectively preventing droplets from quickly filling the pores of the filter medium. This significantly extends the service life of the filter medium in the filtration mechanism and reduces maintenance costs and downtime associated with frequent replacement or cleaning of the filter medium. The outer and inner deflector plates with the "V"-shaped structure increase the contact area with the airflow, allowing for more complete and uniform separation of heavy components and improving the overall gas-liquid separation efficiency.

Detailed Implementation

[0022] Please see Figure 1-5 This utility model provides a filter-type gas-liquid separator, including a separator cylinder 1. A gas flow guiding mechanism 2 is fixedly installed inside the separator cylinder 1, and a gas flow deflection mechanism 3 is installed on the lower side of the gas flow guiding mechanism 2. The gas flow deflection mechanism 3 includes a fixed seat 33 fixedly connected to the inner wall of the separator cylinder 1, and an outer deflection plate 31 is screwed to the end of the fixed seat 33. At the same time, an inner deflection plate 32 is fixedly installed on the inner side of the outer deflection plate 31. An air inlet pipe 21 is installed directly above the gas flow deflection mechanism 3, and a filter mechanism 12 is fixedly installed on the upper side of the inside of the separator cylinder 1.

[0023] Working principle: In actual use, the liquid-containing gas jet enters the air inlet pipe 21 and impacts the gas tank 22. As the air pressure inside the gas tank 22 increases, the airflow inside the gas tank 22 overflows and impacts the surface of the gas jet deflector 3, allowing the airflow to evenly collide with the outer deflector plate 31 and the inner deflector plate 32 on the surface of the gas jet deflector 3. The cross-sections of the outer deflector plate 31 and the inner deflector plate 32 are both "V" shaped. Due to inertia, the heavier components in the gas jet remain on the gas jet deflector 3 and pass through... The gas enters the liquid collection hopper 11 through the leakage hole on the gas beam deflector 3 for collection. At this time, a blind plate can be installed at the collection port at the bottom of the liquid collection hopper 11 to prevent the gas from leaking from the bottom opening of the liquid collection hopper 11. At the same time, the light component gas moves upward, is filtered by the filter mechanism 12, and is discharged from the gas release hopper 13. The gas beam can be pre-separated between the filtered gas and liquid by the gas beam guide mechanism 2 and the gas beam deflector 3 to prevent the droplets from quickly filling the pores of the filter medium and improve the filtration efficiency and effect of the filter mechanism 12.

[0024] In a preferred embodiment, a gas release hopper 13 is fixedly provided at the upper end of the separator cylinder 1, and a liquid collection hopper 11 is fixedly provided at the lower end of the separator cylinder 1. Both the liquid collection hopper 11 and the gas release hopper 13 are conical.

[0025] The air jet guiding mechanism 2 includes an air inlet pipe 21, an air tank 22, an overflow plate 23, an overflow pipe 24, and a support base 25. Three sets of support bases 25 are installed at equal intervals at the bottom of the overflow plate 23, and the ends of the three sets of support bases 25 are all fixed to the inner circumference of the separator cylinder 1.

[0026] An outer exhaust channel and an inner exhaust channel are installed on the overflow plate 23. The bottom of the outer exhaust channel is opposite to the outer baffle plate 31, and the bottom of the inner exhaust channel is opposite to the inner baffle plate 32.

[0027] Both the outer and inner exhaust channels are composed of multiple sets of overflow pipes 24 that are equidistantly distributed, with the upper end face of the overflow pipe 24 passing through the overflow plate 23.

[0028] like Figure 1 and Figure 4As shown: The outer and inner exhaust channels on the overflow plate 23 are respectively positioned opposite the outer baffle plate 31 and the inner baffle plate 32, allowing the airflow in the gas tank 22 to be accurately guided to the corresponding baffle plates through the corresponding channels. This ensures sufficient collision between the airflow and the outer and inner baffle plates 31 and 32, improving gas-liquid separation efficiency. Both the outer and inner exhaust channels are composed of multiple sets of overflow pipes 24 distributed at equal intervals, with the upper end face of the overflow pipes 24 passing through the overflow plate 23. This structure allows the airflow to be evenly distributed to each overflow pipe 24. The airflow impacts the baffle plate at a stable velocity, avoiding excessively strong or weak local airflow that could affect the separation effect. At the same time, the design of multiple overflow pipes 24 increases the exhaust area, which can effectively balance the air pressure in the air tank 22 and prevent airflow turbulence caused by excessive air pressure. In addition, the equidistantly distributed overflow pipes 24 can make the airflow more evenly distributed on the surface of the baffle plate, so that the heavy components in the air bundle can more fully adhere to the outer baffle plate 31 and the inner baffle plate 32 due to inertia, further improving the pre-separation effect, reducing the burden on the subsequent filtration mechanism 12, and extending its service life.

[0029] An overflow plate 23 is fixedly installed at the bottom of the gas tank 22, and an air inlet pipe 21 is fixedly installed at the upper end of the gas tank 22, and the air inlet pipe 21 is "L" shaped.

[0030] As a preferred embodiment, the cross-sections of the outer baffle plate 31 and the inner baffle plate 32 are both "V" shaped, and a "V" shaped flow channel is formed between the outer baffle plate 31 and the inner baffle plate 32. At the same time, a drain hole is provided at the bottom of the "V" shaped flow channel.

[0031] The air beam guiding mechanism 2 and the air beam deflector mechanism 3 are distributed in parallel. The air beam guiding mechanism 2 and the air beam deflector mechanism 3 are combined together to form the gas-liquid pre-separation mechanism of the air beam.

[0032] like Figure 1-5As shown: The air jet containing liquid is guided into the inlet pipe 21 by the air jet guide mechanism 2 and impacts the air tank 22. The increased air pressure inside the air tank 22 causes the airflow to overflow and impact the air jet deflector mechanism 3. With the help of the structural features of the outer deflector plate 31 and the inner deflector plate 32 with a "V" shaped cross section, combined with inertia, the heavy components in the air jet are efficiently attached and enter the liquid collection hopper 11 through the leakage hole for collection, while the light components of the gas rise smoothly. The pre-separation design achieved by the air jet guide mechanism 2 and the air jet deflector mechanism 3 can separate a large number of droplets before the air jet enters the filter mechanism 12 for final filtration, effectively preventing the droplets from quickly filling the pores of the filter medium, thereby significantly extending the filtration time of the filter medium in the filter mechanism 12. The pre-separation process extends the service life of the filter media, reducing maintenance costs and downtime associated with frequent replacement or cleaning. Simultaneously, the pre-separation process pre-purifies the gas stream, significantly reducing the filtration burden on the subsequent filtration mechanism 12. This allows for more efficient and precise filtration of lighter gas components, ensuring the purity and quality of the gas discharged from the gas release hopper 13. Furthermore, the "V"-shaped outer baffle plate 31 and inner baffle plate 32 increase the contact area with the airflow, allowing for more thorough and uniform separation of heavier components, thus improving overall gas-liquid separation efficiency. The liquid collection hopper 11 ensures the orderly collection of separated liquids, facilitating subsequent processing or recycling and preventing equipment contamination or waste caused by uncontrolled liquid flow.
