Description

Technical Field

[0001] This utility model belongs to the technical field of gas emission, and relates to a gas emission silencing device, specifically a high-pressure, high-flow safety silencing device. Background Technology

[0002] Industrial gases have a wide range of applications, including chemical industry, medical and health care, metallurgy, mining, and semiconductor industry. During gas emission, significant noise is generated due to friction between the gas and the exhaust pipe walls during flow, as well as gas impact. Therefore, silencers are needed to reduce noise and make the gas emission process quieter. However, in practical use, they still have the following drawbacks:

[0003] 1. During the silencing process, the gas is directly discharged into the silencer and the silencer components are used for silencing. During the high-pressure and high-flow gas transportation process, when the pressure in the gas decreases, the oil and water in it are easy to condense. After condensation, they remain in the silencer and affect the silencing effect of the silencer.

[0004] 2. The silencer directly uses a silencer to reduce noise. During the silencer process, the air is discharged directly upwards. The pressure is still relatively high when it is discharged. When the pressure is high, the noise emitted from the outlet is relatively high, which has a relatively large impact on the environment. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a high-pressure, high-flow-rate safety silencing device. By incorporating a pressure-reducing tank, an inner filter disc, and a top cylinder, it solves the problem of condensate retention affecting the silencing effect, achieves gas-liquid separation, and improves the silencing effect during exhaust.

[0006] The technical solution of this utility model is as follows:

[0007] A high-pressure, high-flow-rate safety silencing device includes a pressure reducing tank, an inner filter disc II, and a top cylinder. The inner filter disc II is fixed to the lower part of the internal cavity of the pressure reducing tank. The inner filter disc II has a structure with both the top and bottom being disc-shaped, and the two disc-shaped discs are separated by a fixing plate. The fixing plate has evenly arranged vent holes. A delivery pipe connects to the lower part of the internal cavity of the pressure reducing tank from the side wall, with the delivery pipe facing the side of the fixing plate of the inner filter disc II. A bottom pipe for draining liquid is connected to the lower part of the pressure reducing tank, and the top cylinder is connected to the upper part of the pressure reducing tank. The top cylinder includes an outer cylinder and an inner cylinder coaxially mounted. The inner cylinder is an exhaust cylinder with an exhaust hole structure, and the outer cylinder is a closed cylinder structure with an exhaust port on the side.

[0008] Furthermore, the inner filter plate is also equipped with a partition plate, which is horizontally positioned at the location of the delivery pipe corresponding to the pressure reducing tank.

[0009] Furthermore, the upper part of the internal cavity of the pressure reducing tank is provided with an inner filter plate 1, which is fixed above an inner filter plate 2. The inner filter plate 1 is a filter structure.

[0010] Furthermore, the bottom disc of the second inner filter disc is a rigid filter disc, which is a filter screen structure, and the top disc of the second inner filter disc is a microporous structure with a conical surface.

[0011] Furthermore, an electrically controlled valve is installed at the bottom pipe to control the opening and closing of the bottom pipe.

[0012] Furthermore, a support ring is fixed on the outer circumference of the middle part of the pressure-reducing tank.

[0013] Furthermore, a sound-absorbing material is placed inside the pressure-reducing tank on the side of the partition plate away from the delivery pipe. The sound-absorbing material can be almost anything, and its function is to make the chambers on both sides of the partition plate 203 unequal, thereby improving the sound-absorbing effect.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model solves the problem of condensate retention in the silencer affecting the silencer effect by setting up a pressure-reducing tank, an inner filter plate II, and a top cylinder. The delivery pipe delivers high-pressure gas to the pressure-reducing tank. The gas is delivered between the fixed plate below the partition plate and the inner wall of the pressure-reducing tank. After the gas and droplets are depressurized, they are homogenized and delivered to the pressure-reducing tank between the inner filter plate II and the hard filter plate. After the pressure is reduced, the droplets are filtered by the inner filter plate I, the gas rises, and the droplets fall onto the hard filter plate. After being filtered by the hard filter plate, they fall to the bottom of the pressure-reducing tank. The gas rises by the inner filter plate II and is then delivered to the inner filter plate I at the top of the pressure-reducing tank for further filtration before being delivered to the connecting pipe. After a certain amount of oil-water mixture is deposited in the pressure-reducing tank, the electric control valve is opened, allowing the liquid in the pressure-reducing tank to be output through the bottom pipe. This allows for good liquid separation in the gas, minimizing the impact on the working effect.

[0016] 2. This utility model solves the problem of insufficient noise reduction effect when the silencer is venting by setting a pressure reducing tank and a top cylinder. The gas is delivered to the space between the top cylinder and the exhaust cylinder through the exhaust holes on the side of the exhaust cylinder, and then discharged through the exhaust port. When the gas is working, the pressure is reduced when the gas passes through the exhaust holes on the side of the exhaust cylinder, reducing the vibration during output. Finally, the gas is discharged through the exhaust port, resulting in a better noise reduction effect when the silencer is venting. Attached Figure Description

The inner filter disc 2 is fixed to the lower part of the internal cavity of the pressure reducing tank 1. The inner filter disc 2 has a structure with both the top and bottom being discs. The two discs are separated by a fixing plate 201. The fixing plate 201 has evenly arranged vent holes 202. A conveying pipe 106 connects to the lower part of the internal cavity of the pressure reducing tank 1 from the side wall. The conveying pipe 106 faces the side of the fixing plate 201 of the inner filter disc 2. A bottom pipe 107 for draining liquid is connected to the lower part of the pressure reducing tank 1, and the top cylinder 3 is connected to the upper part of the pressure reducing tank 1.

[0036] Example 2:

[0037] Please see Figure 1-5This utility model is a high-pressure, high-flow safety silencing device, including a pressure reducing tank 1, an inner filter disc 2, and a top cylinder 3. The inner filter disc 2 is fixed to the lower part of the inner wall of the pressure reducing tank 1. When the pressure reducing tank 1 is working, high-pressure gas passes through it, thereby reducing the delivery pressure of the high-pressure gas. A fixing plate 201 is fixed to the bottom end of the inner filter disc 2, which further reduces the pressure of the gas entering the pressure reducing tank 1. A partition plate 203 is fixed to the upper part of the side of the fixing plate 201 away from the center of the inner filter disc 2, which separates the gas between the fixing plate 201 and the delivery pipe 106 on the pressure reducing tank 1. The partition plate 203 is fixed to the inner wall of the pressure reducing tank 1. The top cylinder 3 is set above the pressure reducing tank 1, which discharges excess pressurized gas and reduces the pressure. An exhaust pipe 302 is fixed to the center of the top and bottom of the inner wall of the top cylinder 3, which discharges the gas into the space between the top cylinder 3 and the exhaust pipe 302.

[0038] Specifically, a support ring 105 is fixed on the outer circumferential surface of the middle part of the pressure reducing tank 1, and a delivery pipe 106 is fixedly connected to the outer circumferential surface of the pressure reducing tank 1 below the support ring 105. The central axis of the delivery pipe 106 is perpendicular to the side of the fixed plate 201. The pressure reducing tank 1 is provided with the support ring 105 to support the installation of the external support structure, and the high-pressure gas is delivered to the pressure reducing tank 1 through the delivery pipe 106.

[0039] An inner filter plate 104 is fixed on the inner wall of the pressure reducing tank 1 above the inner filter plate 2. A bottom pipe 107 is fixedly connected to the bottom end of the pressure reducing tank 1. An electric control valve 108 is fixed on the periphery of the bottom pipe 107. The pressure reducing tank 1 further filters the liquid droplets in the high-pressure gas through the inner filter plate 104 and then delivers them to the connecting pipe 101. The opening and closing of the bottom pipe 107 is controlled by the electric control valve 108. When the electric control valve 108 is opened, the oil-water mixture in the pressure reducing tank 1 is output through the bottom pipe 107.

[0040] The top of the pressure-reducing tank 1 and the bottom of the top cylinder 3 are both fixedly connected to a connecting pipe 101. The two connecting pipes 101 are fixed with mounting rings 102 on their periphery at the ends that are close to each other. The two mounting rings 102 abut against each other. The two mounting rings 102 are arranged in a ring array and are connected to a fastening component 103. The pressure-reducing tank 1 is connected to the connecting pipe 101 on the top cylinder 3 through the connecting pipe 101. The two connecting pipes 101 are connected to the fastening component 103 through the mounting rings 102. After the fastening component 103 is tightened, the pressure-reducing tank 1 and the top cylinder 3 are fixed together.

[0041] The fixed plate 201 below the partition 203 has a uniformly perforated air hole 202 on one side. A rigid filter plate 204 is fixed to the bottom of the fixed plate 201. The rigid filter plate 204 is fixed to the inner wall of the pressure reducing tank 1. The partition 203 will allow air to pass through the air hole 202. After the liquid droplets collected in the gas are filtered by the rigid filter plate 204, they fall to the bottom of the pressure reducing tank 1.

[0042] The operation process of this embodiment is as follows: During operation, high-pressure gas is delivered to the pressure reducing tank 1 through the delivery pipe 106. The gas is delivered between the fixed plate 201 below the partition plate 203 and the inner wall of the pressure reducing tank 1. After the gas and liquid droplets are depressurized, they are homogenized and delivered to the pressure reducing tank 1 between the inner filter plate 2 and the hard filter plate 204. After the pressure is reduced, the liquid droplets are filtered by the inner filter plate 104. The gas rises and the liquid droplets fall onto the hard filter plate 204. After being filtered by the hard filter plate 204, they fall to the bottom of the pressure reducing tank 1. After the gas rises on the inner filter plate 2, it is delivered to the inner filter plate 104 at the top of the pressure reducing tank 1. After further filtration, it is delivered to the connecting pipe 101. After a certain amount of oil-water mixture is deposited in the pressure reducing tank 1, the electric control valve 108 is opened, so that the liquid in the pressure reducing tank 1 is output through the bottom pipe 107.

[0043] Example 3:

[0044] Please see Figure 1 , 2 4. Based on the specific embodiment one, the top cylinder 3 has an exhaust port 301 symmetrically fixedly connected to the center of its periphery, and the exhaust cylinder 302 has an exhaust hole 303 uniformly opened through its periphery. The top cylinder 3 discharges the gas that enters it through the exhaust port 301, and the high-pressure gas that enters the exhaust cylinder 302 is discharged through the exhaust hole 303.

[0045] The operation process of this embodiment is as follows: after the gas is filtered and transported to the connecting pipe 101, it rises and is transported to the exhaust pipe 302 inside the top cylinder 3. It is then transported to the space between the top cylinder 3 and the exhaust pipe 302 through the exhaust holes 303 on the periphery of the exhaust pipe 302, and then discharged through the exhaust port 301. This reduces the pressure and vibration during output when the gas passes through the exhaust holes 303 on the periphery of the exhaust pipe 302 during operation, and finally discharges through the exhaust port 301.
