[0042] Please refer to Figures 1 to 2 , Figure 1 is a schematic view of the appearance of the emptying device, Figure 2 is a schematic view of the appearance of the sealing member, an embodiment discloses a high-temperature flue gas pipeline emptying device, which comprises a first pipeline member 1, the first pipeline member 1 comprises an air inlet end and an air outlet end in communication with the flue gas pipeline; the connecting member 2 is arranged at the air outlet end position of the first pipeline member 1; the air inlet end position of the second pipeline member 4 is coupled with the air outlet end of the first pipeline member 1 through the connecting member 2, and the side wall of the second pipeline member 4 is provided with a plurality of first through holes; wherein, the first gap is arranged between the air outlet end of the first pipeline member 1 and the air inlet end of the second pipeline member 4, and the sealing member 3 is arranged at the position of the first gap, the sealing member 3 comprises a clamping part 31 and a sealing diaphragm 32 clamped by the clamping part 31.
[0043] Specifically, the venting device in the embodiment includes a first pipe member 1, a connecting member 2, a sealing member 3, and a second pipe member 4; the first pipe member 1 is connected to a main pipe for conveying medium, has an air inlet end and an air outlet end, the air inlet end is used for receiving high-temperature flue gas from the main pipe when the main pipe needs to be vented, and the air outlet end is designed to be in communication with a downstream flue gas pipe or an external environment; the connecting member 2 is arranged at the air outlet end of the first pipe member 1, connects the first pipe member and the second pipe member, and ensures the structural stability therebetween, the connecting member can be a flange, a bolt, or other standard connecting piece, so as to facilitate installation, disassembly, and maintenance, and is not specifically limited in the embodiment; through the fastening action of the connecting member, the first pipe member and the second pipe member can form effective communication when needed.
[0044] There is a first gap between the air outlet end of the first pipe member 1 and the air inlet end of the second pipe member 4, and the sealing member 3 is arranged in the first gap; the sealing member 3 is composed of a clamping part 31 and a sealing diaphragm 32 clamped by the clamping part 31. The clamping part 31 can be a metal or non-metal frame for fixing and supporting the sealing diaphragm 32, so as to ensure that the sealing diaphragm 32 maintains a stable position and form during use; the sealing diaphragm 32 plays a role in blocking the communication between the first pipe member and the second pipe member in a normal state, and high-temperature flue gas cannot leak or be discharged through the second pipe member 4 under normal working conditions; when the pressure in the main pipe abnormally rises due to some reasons (such as equipment failure, operation error, or external factor interference), the sealing diaphragm 32 will bear a huge pressure; in this case, the sealing diaphragm breaks when a certain pressure threshold is reached, forming a safe pressure relief channel; in an embodiment, the pressure value that the sealing diaphragm 32 can bear is between 0.5-1.0 MPa, please refer to Figure 3 , Figure 3 The figure is a schematic view of a broken state of the sealing member; after the sealing diaphragm 32 is broken, the first pipe member and the second pipe member form a communication state, and high-temperature and high-pressure flue gas can be rapidly released to the external environment through the first through holes in the side wall of the second pipe member, so as to reduce the pressure in the pipe; in the embodiment, manual operation on the pressure relief valve is not required, and the safety is higher.
[0045] Please continue to refer to Figure 2In an embodiment, the sealing diaphragm 32 is made of stainless steel and has a circular shape. A "cross" mark is formed on the surface of the sealing diaphragm 32 away from the first pipe member 1. When the pressure in the pipe abnormally rises, the diaphragm breaks at the mark, thereby forming a controlled pressure relief channel. Compared with random breaking, the breaking through the mark is predictable, which ensures that the breaking occurs at a predetermined position and avoids the problems of poor pressure relief or other safety problems caused by uncertain breaking position. When the pressure in the pipe reaches or exceeds the bearing limit of the sealing diaphragm 32, the diaphragm breaks along the "cross" mark, and a communication is formed between the first pipe member 1 and the second pipe member 4. The high-temperature and high-pressure flue gas is then rapidly released to the outside through the first through hole in the side wall of the second pipe member 4, thereby reducing the pressure in the pipe system.
[0046] Please continue to refer to Figure 1 In an embodiment, the connecting member 2 includes two oppositely arranged flange members. One flange member is connected to the first pipe member 1, and the other flange member is connected to the second pipe member 4. The two flange members are detachably connected through a bolt assembly. In the implementation process, when it is necessary to connect the first pipe member 1 and the second pipe member 4, the two flange members are aligned, and then the bolt assembly is used to fasten them together. When it is necessary to disassemble, the bolt assembly is loosened, and the two flange members can be separated. This connection method is relatively simple. One side of the two flange members arranged oppositely is provided with a mounting area for mounting the sealing member 3. When the two flange members are mounted, the clamping portion 31 is clamped to fix the position of the sealing member 3.
[0047] Please refer to Figure 5 and Figure 4 , Figure 4 is a schematic view of the appearance of the second pipe member, Figure 5 is a schematic view of the connection between the second pipe member and the flange member. In an embodiment, the second pipe member 4 includes a pressure relief pipe 41, and the pressure relief pipe 41 is provided with an opening at one end. A plate member 42 is arranged at the opening edge area of the pressure relief pipe 41. One flange member is sleeved on the pressure relief pipe 41, and the surface of one side of the pressure relief pipe 41 contacts the plate member 42. The plate member 42 effectively limits the flange member. When the flange member is sleeved on the pressure relief pipe 41, the other flange member can be fixedly installed on the surface of the first pipe member 1. When the two flange members form a whole, the plate member 42 is extruded, and the two flange members are not displaced or detached due to pressure changes or external environment. When it is necessary to disassemble the pressure relief pipe, the operator can disassemble the bolt to separate the flange members, and then move the flange member sleeved on the pressure relief pipe 41.
[0048] In another embodiment, the top of the pressure relief pipeline 41 is also provided with a first through hole, wherein the top of the pressure relief pipeline 41 is detachably provided with a shielding member 5, and the shielding member 5 at least covers the top of the pressure relief pipeline 41. Specifically, the first through hole in the top can make the main pipeline be emptied more quickly, and the shielding member 5 at least covering the top of the pressure relief pipeline 41 can protect the pressure relief pipeline 41 from the direct influence of the external environment to some extent, such as the invasion of rainwater, dust or other impurities. If these external factors directly enter the pressure relief pipeline, they can affect the properties of the fluid inside the pipeline, and even cause problems such as blockage or corrosion, thereby affecting the normal play of the pressure relief function. At the same time, the detachable design of the shielding member 5 facilitates future maintenance and repair work, so that the staff can easily remove or install the shielding member 5 as needed to perform necessary cleaning, inspection or replacement operations.
[0049] Please refer to Figure 6 , Figure 6 For a structural diagram of the shielding member 5, in another embodiment, the shielding member includes a top plate arranged above the top of the pressure relief pipeline; one end of a plurality of support rods is respectively connected to the edge region of the top plate, and the other end is respectively connected to the outer wall of the pressure relief pipeline; wherein the middle region of the top plate is provided with a mounting through hole, and a filter screen member is detachably connected at the position of the mounting through hole; Figure 6 The position a is the mounting through hole, and the position b is the filter screen member. Further, the filter screen member includes an annular frame, and the outer contour of the annular frame matches the second through hole; the filter screen is arranged in the annular frame, and the second pipeline member further includes a reinforcing rib, a plurality of reinforcing ribs are arranged on the outer wall of the pressure relief pipeline, and each reinforcing rib is arranged in the extension direction of the pressure relief pipeline; wherein the cross-sectional shape of the reinforcing rib is triangular, and one side of the reinforcing rib is connected to the outer wall of the pressure relief pipeline. Specifically, one mounting through hole is arranged in the middle region of the top plate. The pressure relief pipeline can be relieved through the mounting through hole in the pressure relief state, and the mounting through hole provides a mounting area for the filter screen member. The filter screen member is composed of an annular frame and a filter screen, and the outer contour of the annular frame matches the mounting through hole, ensuring that it can be tightly and stably installed at the through hole position. The filter screen is arranged in the annular frame to prevent external impurities (such as dust, small particles, etc.) from entering the pressure relief pipeline through the mounting through hole, thereby maintaining the cleanliness and smoothness of the pipeline. In order to prevent rainwater from entering the pipeline through the mounting through hole, a shielding plate is arranged directly above the mounting through hole. Please continue to refer to Figure 6 The position c is the shielding plate, which is supported by a columnar support.
