[0001] The utility model belongs to the technical field of compressed air treatment, and particularly relates to a gas-liquid mixture separation and noise reduction device. Background Art

[0002] In the field of compressed air treatment, as an indispensable device, the cold dryer effectively removes most of the moisture in the compressed air through its efficient cooling and condensation mechanism, providing dry and pure compressed air for subsequent industrial production. However, during the operation of the cold dryer, after the compressed air is cooled, the moisture in it condenses into a liquid state and mixes with oil and impurities to form a gas-liquid mixture.

[0003] When the gas-liquid mixture is discharged outward at high speed through the discharge port of the cold dryer, it will be accompanied by huge noise pollution, which not only affects the environmental quality of the production workshop, but also may pose a threat to the hearing health of employees. In addition, the high-speed discharge of the gas-liquid mixture makes it difficult to recycle and separate, affecting the normal operation and maintenance of surrounding production equipment.

[0004] Therefore, there is an urgent need to design a device that can effectively separate the gas-liquid mixture and reduce noise. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems of difficult separation of the high-speed discharged gas-liquid mixture and the resulting noise pollution in the prior art, and a gas-liquid mixture separation and noise reduction device is proposed. This device can not only effectively separate the gas-liquid mixture to recover the liquid therein, but also significantly reduce the noise generated during the high-speed discharge of the gas-liquid mixture and improve the production environment.

[0006] To achieve the above purpose, the technical solutions adopted are as follows:

[0007] An outer cylinder body, which is connected to a sewage discharge device, and the sewage discharge device can discharge a high-speed gas-liquid mixture;

[0008] And an inner cylinder body, which is used for separating the gas-liquid mixture. The inner cylinder body is fixedly sleeved inside the outer cylinder body, and a plurality of through holes are evenly arranged on the side wall of the inner cylinder body;

[0009] A sound absorption cavity is formed between the outer cylinder body and the inner cylinder body, and the high-speed gas-liquid mixture undergoes a zigzag rebound and sound absorption in the sound absorption cavity.

[0010] According to the gas-liquid mixture separation and noise reduction device of the utility model, further, at least one air inlet hole is arranged on the upper part of the side wall of the outer cylinder body, an exhaust hole is arranged at the top, and a liquid discharge hole is arranged at the bottom.

[0011] According to the gas-liquid mixture separation and silencing device of the present utility model, further, an inclined intake pipe is screwed at the intake hole of the outer cylinder body, and the inclination angle of the intake pipe is 30°-60°.

[0012] According to the gas-liquid mixture separation and silencing device of the present utility model, further, a detection hole is opened at the lower part of the side wall of the outer cylinder body, and a liquid level probe is screwed at the detection hole.

[0013] According to the gas-liquid mixture separation and silencing device of the present utility model, further, a drain valve is screwed at the liquid discharge hole of the outer cylinder body, and the drain valve is connected to a waste liquid tank through a pipeline.

[0014] According to the gas-liquid mixture separation and silencing device of the present utility model, further, the inner cylinder body is a cylinder surrounded by a top plate, side plates and a bottom plate that are fixedly connected to each other in pairs, and a plurality of through holes are opened on the top plate, side plates and bottom plate.

[0015] According to the gas-liquid mixture separation and silencing device of the present utility model, further, the top plate is horizontally fixedly arranged on the inner side wall of the outer cylinder body, and the top plate is located above the intake hole; the distribution range of the through holes on the side plates is below the intake hole.

[0016] According to the gas-liquid mixture separation and silencing device of the present utility model, further, the area surrounded by the top plate, side plates and the inner side wall of the outer cylinder body is a silencing cavity; the high-speed gas-liquid mixture enters the silencing cavity from the intake pipe and undergoes a folded rebound silencing in the silencing cavity.

[0017] According to the gas-liquid mixture separation and silencing device of the present utility model, further, a sound-absorbing cotton is also coated on the outer wall of the outer cylinder body.

[0018] According to the gas-liquid mixture separation and silencing device of the present utility model, further, a mounting plate is fixedly arranged on the outer side wall of the outer cylinder body, and the materials of the outer cylinder body, inner cylinder body and mounting plate are all high-strength anti-corrosion materials.

[0019] Adopting the above technical solution, the beneficial effects obtained are:

[0020] The present utility model is ingeniously designed and has a simple structure. It can effectively separate the gas-liquid mixture and significantly reduce the noise generated by the high-speed discharge of the gas-liquid mixture.

[0021] 1) The high-speed gas-liquid mixture rebounds repeatedly in a folded line in the silencing cavity, thereby reducing the flow rate of the high-speed gas-liquid mixture and the energy it carries, so as to achieve the effect of noise reduction and silencing.

[0022] 2) The intake pipe is arranged obliquely on the outer cylinder body, avoiding the direct impact of the high-speed gas-liquid mixture entering the outer cylinder body from the intake pipe on the inner cylinder body, reducing the impact angle of the high-speed gas-liquid mixture on the inner cylinder body, further improving the sound absorption and noise reduction effect, and at the same time avoiding the direct reflection of the gas-liquid mixture back into the intake pipe due to direct impact and preventing it from smoothly entering the sound absorption cavity.

[0023] 3) Through the repeated rebounding of the high-speed gas-liquid mixture in the sound absorption cavity, the gas-liquid mixture flowing into the bottom of the outer cylinder body tends to a stable state. The gas in the gas-liquid mixture (under the action of buoyancy) gradually floats out of the liquid and enters the inner cylinder body through the through holes on the inner cylinder body, and then is discharged into the atmosphere through the exhaust holes of the outer cylinder body, thereby realizing the effect of gas-liquid separation and facilitating the recovery of waste liquid.

[0031] In the following, the exemplary solutions of the embodiments of the present invention will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present invention. Unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meanings understood by those of ordinary skill in the art.

[0032] Such as Figure 1As shown in the figure, the gas-liquid mixture separation and noise reduction device of this embodiment includes an outer cylinder 1 and an inner cylinder 2. The outer cylinder 1 is connected to a sewage discharge device, which can discharge a high-speed gas-liquid mixture; the inner cylinder 2 is used to separate the gas-liquid mixture. The inner cylinder 2 is fixedly sleeved inside the outer cylinder 1, and a plurality of through holes 204 are evenly opened on the side wall of the inner cylinder 2; a noise reduction cavity 210 is formed between the outer cylinder 1 and the inner cylinder 2, and the gas-liquid mixture undergoes zigzag rebound noise reduction in the noise reduction cavity 210. The combined use of the outer cylinder 1, the inner cylinder 2 and the noise reduction cavity 210 formed therebetween can not only reduce the noise generated by the high-speed discharged gas-liquid mixture, but also effectively separate the gas-liquid mixture.

[0033] Further, the sewage discharge device is a cold dryer, and there are two discharge ports on the cold dryer for discharging the high-speed gas-liquid mixture.

[0034] Further, both the outer cylinder 1 and the inner cylinder 2 are cylindrical.

[0035] As Figure 1 shown, at least one air inlet hole 101 is opened in the upper part of the side wall of the outer cylinder 1, an exhaust hole 103 is opened at the top, and a liquid discharge hole 104 is opened at the bottom.

[0036] Preferably, the number of the air inlet holes 101 is two. The two air inlet holes 101 are sequentially opened on the outer cylinder 1 in the vertical direction, and the two air inlet holes 101 are respectively connected to the two discharge ports of the above-mentioned cold dryer for discharging the gas-liquid mixture through connecting pipes.

[0037] Further, there is also a sewage discharge hole on the above-mentioned cold dryer, and the sewage discharged from this sewage discharge hole also contains a small amount of gas. Therefore, a sewage inlet hole 102 is also opened on the outer cylinder 1, and the sewage inlet hole 102 is used to connect to the sewage discharge hole of the above-mentioned cold dryer in order to separate the sewage and gas mixture discharged from this sewage discharge hole.

[0038] Further, a plurality of air inlet holes 101 and sewage inlet holes 102 can be opened on the side wall of the outer cylinder 1 in order to connect to a plurality of cold dryers.

[0039] As Figure 1 shown, an inclined air inlet pipe 1011 is screwed at the air inlet hole 101 of the outer cylinder 1, and the inclination angle of the air inlet pipe 1011 is 30° - 60°.

[0040] As Figure 1 shown, a detection hole 105 is also opened in the lower part of the side wall of the outer cylinder 1, and the detection hole 105 is located below the air inlet hole 101. A liquid level probe 1051 is screwed at the detection hole 105, and the liquid level probe 1051 is used to detect the height of the liquid in the outer cylinder 1.

[0041] As Figure 1As shown, a drain valve 106 is screwed at the liquid drain hole 104 of the outer cylinder body 1, and the drain valve 106 is connected to an external waste liquid tank through a pipeline.

[0042] Further, the liquid level probe 1051 and the drain valve 106 are both electrically connected to an external controller, and the controller can receive the liquid level signal sent by the liquid level probe 1051 and control the opening and closing of the drain valve 106.

[0043] As Figure 2 shown, the inner cylinder body 2 is a cylinder formed by enclosing a top plate 201 and side plates 203 which are welded to each other in pairs and side plates 203 and a bottom plate 202, and a plurality of through holes 204 are formed in the top plate 201, side plates 203 and bottom plate 202.

[0044] As Figure 2 shown, the top plate 201 is horizontally welded to the inner side wall of the outer cylinder body 1, and the top plate 201 is located above the air inlet hole 201.

[0045] Further, the distribution range of the through holes 204 on the side plates 203 is below the air inlet hole 101.

[0046] As Figure 2 shown, the top plate 201, side plates 203 and the inner side wall of the outer cylinder body 1 enclose a sound absorption cavity 210, and the high-speed gas-liquid mixture enters the sound absorption cavity 210 through the air inlet pipe 1011 and undergoes a folded rebound sound absorption in the rebound cavity 210.

[0047] Specifically, the high-speed gas-liquid mixture entering the sound absorption cavity 210 from the air inlet pipe 1011 will undergo repeated folded rebounds in the sound absorption cavity 210, thereby reducing the flow rate of the high-speed gas-liquid mixture and the energy carried by it, so as to achieve the effect of sound absorption and noise reduction.

[0048] It should be understood that since the air inlet pipe 1011 is inclinedly arranged on the outer cylinder body 1, the high-speed gas-liquid mixture entering the outer cylinder body 1 from the air inlet pipe 1011 is prevented from directly hitting the inner cylinder body 2, the impact angle of the high-speed gas-liquid mixture on the inner cylinder body 2 is reduced, while further improving the sound absorption and noise reduction effect, and the direct reflection of the gas-liquid mixture back into the air inlet pipe due to direct hitting is avoided.

[0049] It should be understood that since the through hole range on the side plates 203 is only below the air inlet hole 101, the high-speed gas-liquid mixture is prevented from directly spraying into the inner cylinder body 2 through the air inlet pipe 1011. To increase the rebound range (and number of times) of the high-speed gas-liquid mixture in the sound absorption cavity 210, so that the flow rate of the gas-liquid mixture and the energy carried by it are fully reduced.

[0050] It should be understood that as Figure 2As shown, the high-speed gas-liquid mixture rebounds repeatedly in the sound-absorbing cavity 210, becomes stable, and gradually flows towards the bottom of the outer cylinder 1. The gas in the gas-liquid mixture at the bottom of the outer cylinder 1 gradually separates from the liquid under the action of buoyancy and enters the inner cylinder 1 through the through holes 204 in the side plate 203 and the bottom plate 202.

[0051] At this time, the separation of the gas-liquid mixture is achieved. The separated gas is discharged through the through holes 204 in the bottom plate 201 and the exhaust holes 103 at the top of the outer cylinder 1, and the liquid is discharged from the liquid discharge hole 104 at the bottom of the outer cylinder 1.

[0052] Furthermore, the outer cylinder 1 is also covered with sound-absorbing cotton, which is used for further sound absorption and noise reduction.

[0053] As Figure 1 shown, the mounting plate 3 is welded to the outside of the side wall of the outer cylinder 1, and the separation and sound-absorbing device is installed on the corresponding surrounding frame through the mounting plate 3.

[0054] Furthermore, the materials of the outer cylinder 1, the inner cylinder 2, and the mounting plate 3 are all corrosion-resistant materials, such as stainless steel.

[0055] The working principle is as follows:

[0056] In the initial state, the drain valve 106 is in the closed state.

[0057] S1. Connect the intake pipe 1011 of the outer cylinder 1 to the gas-liquid mixture discharge port of the cold dryer, and the cold dryer discharges the high-speed gas-liquid mixture intermittently;

[0058] S2. The high-speed gas-liquid mixture enters the sound-absorbing cavity 210 through the intake pipe 1011, and the gas-liquid mixture rebounds repeatedly in a zigzag shape in the sound-absorbing cavity 210, gradually reducing its flow rate and the energy it carries;

[0059] In this way, the sound absorption and noise reduction of the gas-liquid mixture are achieved.

[0060] S3. The gas-liquid mixture flows into the bottom of the outer cylinder 1 and is in a stable state; the gas in the gas-liquid mixture here (under the action of buoyancy) separates from the liquid and enters the inner cylinder 1 through the through holes 204 in the side plate 203 and the bottom plate 202;

[0061] In this way, the separation of the gas-liquid mixture is achieved.

[0062] S4. The separated gas enters the top of the outer cylinder 1 through the through holes 204 in the top plate 201 and is discharged from the exhaust holes 103;

[0063] In S5, the (separated) liquid accumulated at the bottom of the outer cylinder 1 gradually increases. During this process, the liquid level probe 1051 sends the real-time liquid level signal to the controller. When the preset liquid level height is reached, the controller controls the drain valve 106 to open, and the liquid flows into the waste liquid tank through the drain valve 106 for collection.

[0064] It should be noted that when there is a description of an element being "connected", "coupled" or "linked" to another element, it may mean a direct connection, coupling or linkage. However, it should be understood that there may be intermediate elements between the two; that is, it covers the positional relationship of both direct connection and indirect connection.

[0065] It should be noted that the use of words such as "a" or "an" does not necessarily imply a limitation in quantity. Words such as "comprising" or "including" mean that the element or item appearing before this word covers the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0066] It should be noted that terms indicating orientation or positional relationship such as "upper", "lower", "left", "right", etc. are only used to represent the relative positional relationship. This is for the convenience of describing the present utility model, rather than meaning that the device or element must have a specific orientation, be constructed and operated in a specific orientation. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0067] The preferred embodiments for implementing the present utility model have been described in detail above. However, it should be understood that the functions of these embodiments are only for illustration and do not limit the scope, application or construction of the present utility model in any way. The protection scope of the present utility model is defined by the appended claims and their equivalents. Those of ordinary skill in the art can make many changes to the foregoing embodiments under the teaching of the present utility model, and these changes all fall within the protection scope of the present utility model.
