Description

Technical Field

[0001] This utility model belongs to the technical field of spherical tank inspection accessories, specifically referring to a flange-type special exhaust noise reduction device for spherical tank inspection. Background Technology

[0002] According to the inspection requirements for special equipment such as pressure vessels, spherical tanks have an unspecified number of scheduled inspection tasks each year. During inspection, each spherical tank needs to undergo multiple nitrogen purgings and pressure tests on the tank welds using air and water. Previously, this process involved direct venting via a conveyor belt connected to a pipeline vent. However, due to the large volume and high pressure of the compressed gas vented from the spherical tank, the sometimes water-containing vent, the small vent size, and the long periods of open-air venting, the noise was significant, severely impacting the inspection progress and production. Furthermore, because the venting was temporary, the vent installation was often crude, frequently leading to leaks and other unexpected problems, generating considerable noise and posing risks of ground pollution and failure to meet environmental noise standards. Therefore, a flange-type dedicated venting noise reduction device for spherical tank inspection is urgently needed to solve these problems. Utility Model Content

[0003] To solve the aforementioned problems, this utility model provides a flange-type special exhaust noise reducer for spherical tank inspection that requires only on-site installation, meets the exhaust requirements of spherical tank inspection, greatly shortens the exhaust time, significantly improves work efficiency, reduces emission decibels, and meets environmental protection requirements.

[0014] The technical aspects of the present invention will now be described in conjunction with the accompanying drawings of the embodiments thereof.

[0015] The present invention has been clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] As shown in Figures 1 to 3, the flange-type exhaust noise reduction device for spherical tank inspection proposed in this solution includes a cylindrical outer shell 1, a noise reduction inner liner 2, an air inlet pipe 3, and an air outlet pipe 4. The noise reduction inner liner 2 is fixed inside the cylindrical outer shell 1. The air inlet pipe 3 and the air outlet pipe 4 are symmetrically arranged at both ends of the cylindrical outer shell 1. The air inlet pipe 3 passes through the side wall of the cylindrical outer shell 1 and connects to the noise reduction inner liner 2. The air outlet pipe passes through the side wall of the cylindrical outer shell 1 and connects to the noise reduction inner liner 2. The noise reduction inner liner 2 is provided with a noise reduction component 5. The side wall of the noise reduction inner liner 2 is provided with multiple sound-absorbing holes 6. Sound-absorbing material 7 is provided between the noise reduction inner liner 2 and the cylindrical outer shell 1.

[0017] As shown in Figure 3, the noise reduction component 5 includes an air intake support plate 8, an air outlet support plate 9, a silencer plate 10, and a silencer pipe 11. The air intake support plate 8 and the air outlet support plate 9 are symmetrically arranged at both ends of the noise reduction inner liner 2. One end of the air intake pipe 3 passes through the air intake support plate 8, and one end of the air outlet pipe 4 passes through the air outlet support plate 9. The silencer plate 10 is fixed inside the noise reduction inner liner 2 and is located between the air intake support plate 8 and the air outlet support plate 9. The silencer pipe 11 is located inside the noise reduction inner liner 2 and passes through the silencer plate 10.

[0018] The noise-reducing inner liner 2 is provided with an electric heating wire 12 and an electric heating wire 13 at both ends. The electric heating wire 12 is wound around the outside of the air inlet pipe 3, and the electric heating wire 13 is wound around the outside of the air outlet pipe 4. An installation flange 14 is fixed at one end of the air inlet pipe 3 and the air outlet pipe 4. The installation flange 14 is located on the outside of the cylindrical outer shell 1.

[0019] In practical use, the mounting flange 14 of the inlet pipe 3 is connected to the pipeline flange of the spherical tank, and the outlet pipe 4 is connected to a pipeline to discharge to the atmosphere. Direct on-site installation is highly efficient. When the spherical tank exhausts gas, the gas enters the noise-reducing inner liner 2 from the inlet pipe 3. The sound waves impact the silencer plate 10 and lose energy. Some sound waves pass through the silencer holes 6. At this time, the sound-absorbing material 7 between the cylindrical outer shell 1 and the noise-reducing inner liner 2 will absorb the sound wave energy, thereby reducing the exhaust volume.

[0020] The noise level during the process is significantly reduced, the emission time is greatly shortened, the emission decibels are reduced, and environmental protection requirements are met.

[0021] The gas flows along the silencer pipe 11 to the side of the silencer plate 10 near the exhaust pipe 4, and then flows out of the noise-reducing inner liner 2 along the exhaust pipe 4. At the same time, electric heating wire 12 increases the temperature of the intake pipe 3, and electric heating wire 13 increases the temperature of the exhaust pipe 4, accelerating the evaporation of moisture in the gas. This allows the water vapor to be discharged with the gas from the cylindrical outer shell 1, preventing water vapor from condensing inside the noise-reducing inner liner 2. The overall design is compact, efficient, convenient, and environmentally friendly.
