Description

Technical Field

[0001] The invention relates to a corrugated steam-water separation and noise reduction and silencing integrated device, belonging to the technical field of fluid machinery and noise control. Background Art

[0002] In the industrial field, steam ejectors are widely used in various systems. Their working principle is to introduce high-pressure steam to push or compress low-pressure steam or other gases. However, the gas discharged from the steam ejector usually contains a large number of droplets and forms a steam cloud at the outlet. In order to reduce the size of the steam cloud formed at the flue gas outlet, it is necessary to reduce the water droplet content discharged with the flue gas and control the liquefaction and diffusion of the discharged flue gas. In addition, during the operation of the steam ejector, due to the high-speed passage of the airflow and the turbulence effect, significant noise will be generated. This noise not only affects the working environment of the operator, but also causes noise pollution to the surrounding environment. Therefore, it is necessary to design an adaptive steam-water separator and noise reduction muffler in the steam ejector system.

[0003] In the prior art, the steam-water separator and the noise reduction silencer are usually installed independently, and this separate design has many defects. First, the installation of two independent devices requires more space and pipe connections, which increases the complexity and space occupied by the system. Secondly, the independent maintenance and cleaning process is relatively cumbersome, which increases the workload of operators and the maintenance cost of the system. In addition, traditional silencers usually adopt a simple pipeline structure, which has limited noise reduction effect and is prone to resonance at high flow rates, further increasing the noise. The noise reduction effect is limited and cannot fully meet the requirements in high noise environments. Therefore, the development of a device that integrates steam-water separation and noise reduction and silencer functions, which can not only effectively separate droplets but also significantly reduce noise, has become a problem that needs to be urgently solved in the current technical field. Summary of the invention

[0004] (I) Technical Problems to be Solved by the Present Invention

[0005] Integrating steam-water separation and noise reduction functions into one device simplifies system structure, reduces space occupation and installation complexity.

[0006] (II) Technical solution of the present invention

[0007] To achieve the above-mentioned purpose, the present invention provides a corrugated steam-water separation muffler, a combined device of steam-water separation and noise reduction and muffler.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0009] A corrugated steam-water separation muffler, the device comprises a corrugated plate 1, a sound-absorbing perforated plate 6, a water leakage perforated plate 3, and a water collecting box 4;

[0010] The corrugated plate 1, whose bending angle is set to 120°, is a three-sided default structure design, and is combined with the sound-absorbing perforated plates 6 on the front and rear sides and the water leakage perforated plate 3 at the bottom to form a corrugated bent pipe, which has a sealing effect on four sides;

[0011] The water collecting box 4 is provided with a leak hole support plate 4b at the top and a drain pipe 5 at the bottom. Wing plates 4a are provided on the outer sides of the water collecting box 4. The two side wing plates 4a and the water tank support plate 7 on the corrugated plate are combined into a drawer-type structure. The corrugated bent pipe is connected to the water collecting box 4 in a drawer-type combination to form the corrugated bent pipe.

[0012] Connecting flanges 2 are arranged at both ends of the corrugated plate 1, a water tank support plate 7 is arranged inside the connecting flanges 2, and a sound-absorbing perforated plate supporting beam 8 is connected between the connecting flanges; the bending angle of the sound-absorbing perforated plate supporting beam 8 is set to 120° to cooperate with supporting the sound-absorbing perforated plate.

[0013] Furthermore, the sound-absorbing perforated plate 6 uses a micro-perforated plate as a panel, and the hollow part is filled with a metal porous material.

[0014] Furthermore, the length of the corrugated bending pipe is 1200 mm, and the corrugated plate 1 is arranged in a wave shape to achieve steam-water separation.

[0015] Furthermore, the butt joint angle of different sound-absorbing perforated panels is 120°.

[0016] Furthermore, the corrugated steam-water separation muffler has a higher noise reduction effect on noise with a frequency higher than 1000 Hz.

[0017] Furthermore, a plurality of the corrugated steam-water separation silencer devices are connected in series via a connecting flange to achieve better steam-water separation and noise reduction and silencer effects.

[0018] Furthermore, the gas discharged from the steam ejector enters the corrugated bent pipe, and the separated droplets flow down along the inner wall of the pipe, gather into the water collecting tank 4 through the small holes of the leaking orifice plate 3 at the bottom of the corrugated bent pipe, and finally discharge from the system through the drain pipe 5, ensuring the timely discharge of the liquid in the device and avoiding the influence of the accumulated liquid on the system performance.

[0019] Compared with the existing steam-water separators and noise reduction mufflers, the design of the integrated corrugated steam-water separator muffler can perform steam-water separation and noise reduction at the same time, which speeds up the efficiency of droplet separation, reduces the size of the steam cloud formed at the flue gas outlet and significantly reduces noise. It also reduces the number of independent components, simplifies maintenance, improves the system's operational reliability, saves space in the overall structure, and reduces overall use costs.

[0023] (3) Reduce secondary noise;

[0024] (4) Reduce maintenance costs and improve economic efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] (Attached figure identification: 1 corrugated plate; 2 connecting flange; 3 leaking orifice plate; 4 water collecting tank: 4a wing plate, 4b leaking orifice plate support; 5 drainage pipe; 6 sound-absorbing orifice plate; 7 water tank support plate; 8 sound-absorbing orifice plate support beam) DETAILED DESCRIPTION

[0031] The specific structure and technical effects of the present invention are described below in conjunction with the accompanying drawings:

[0032] like Figure 1-Figure 4 As shown, the present invention provides a corrugated steam-water separation muffler, comprising: a corrugated plate 1, a sound-absorbing perforated plate 6, a water leakage perforated plate 3, and a water collecting box 4;

[0033] The corrugated plate 1 has a bending angle of 120° and is a three-sided default structure design. It is combined with the sound-absorbing perforated plates 6 on the front and rear sides and the water leakage perforated plate 3 at the bottom to form a corrugated bent pipe, which has a four-sided sealing effect. The length of the corrugated bent pipe is 1200mm. The corrugated plate 1 is set in a wave shape to achieve steam-water separation.

[0034] The sound-absorbing perforated plate 6 uses a micro-perforated plate as a panel, and the hollow part is filled with a metal porous material. The use of metal porous materials here has obvious advantages because the metal porous materials can still maintain the effect of noise reduction and sound absorption in a soda-water environment, achieving resistive sound absorption. In addition, the metal porous material itself has a capillary effect, which can effectively absorb droplets in the soda-water separation process and improve the separation efficiency. This design allows the sound waves in the airflow to be fully absorbed and reduces noise. In addition, the design of installing sound-absorbing perforated plates on both sides effectively saves the cost of the muffler, and is easier to adjust and replace than a cylindrical muffler, with significant technical and economic advantages.

[0035] Connecting flanges 2 are provided at both ends of the corrugated plate 1, and a plurality of the corrugated steam-water separation silencers are connected in series through the connecting flanges to achieve better steam-water separation and noise reduction and silencer effects.

[0036] like Figure 2 As shown, the water collecting box 4 is provided with a leak hole support plate 4b on the upper part, a drain pipe 5 on the lower part, and wing plates 4a on the outer sides of the water collecting box 4. The wing plates 4a on both sides and the water tank support plate 7 on the corrugated plate are combined into a drawer-type structure, and the corrugated bent pipe is connected with the water collecting box 4 in a drawer-type combination mode to form the corrugated bent pipe; it is easy to assemble and disassemble, easy to replace parts, and maximizes space utilization.

[0037] like Figure 3 As shown, a water tank support plate 7 is arranged inside the flange 2, and a sound-absorbing perforated plate supporting beam 8 is connected between the muffler flanges. The bending angle of the sound-absorbing perforated plate supporting beam 8 is set to 120° to cooperate with supporting the muffler perforated plate and the porous sound-absorbing material.

[0038] like Figure 4 As shown, during the specific implementation, the gas discharged from the steam ejector enters the corrugated bending pipe, which improves the efficiency of steam-water separation. The separated droplets flow down along the inner wall of the pipe, and converge into the water collecting box 4 through the small holes of the leaky orifice plate 3 at the bottom of the pipe, and finally discharge the system through the drain pipe 5, ensuring the timely discharge of the liquid in the device and avoiding the influence of accumulating liquid on the system performance. The leaky orifice plate designed here not only has the function of collecting droplets, but also forms a cavity with the water collector at the bottom. By changing the aperture size of the leaky orifice plate, it can achieve the absorption of sound waves of different frequencies, further enhancing the noise reduction effect. While separating steam and water, hollow sound-absorbing orifice plates 6 are installed on the front and back sides of the corrugated bending pipe. The micro-perforated plate on its surface and the foam metal material filled in the internal cavity fully absorb the sound waves in the airflow to achieve the purpose of reducing noise.

[0039] The gas discharged from the steam ejector enters the flow channel, and the middle of the flow channel is set to be wavy to achieve steam-water separation, where the bending angle of the corrugated pipe is set to 120° and the length is 1200mm. Compared with the straight muffler, the corrugated steam-water separation muffler has a higher noise reduction for noise with a frequency higher than 1000Hz, and the corrugated steam-water separation muffler has a better maximum noise reduction.

[0040] In summary, the present invention provides an integrated steam-water separation and noise reduction muffler, which significantly simplifies the system structure, reduces the occupied space and installation complexity by combining the steam-water separation and noise reduction functions into one. The device uses corrugated bent pipes and micro-perforated plates as panels, and the hollow part is filled with sound-absorbing foam metal materials to achieve efficient droplet separation and noise control, and the steam-water separation effectively improves the operating efficiency of the system. The corrugated plate and the water collection tank are connected in a drawer-type combination, which makes it easy to replace parts of the system, improves maintenance convenience, and significantly reduces costs.
