Description

Technical Field

[0001] This utility model relates to the field of flue gas dust removal technology, and in particular to an anti-condensation pressure transmission structure and a dust collector. Background Technology

[0002] During the operation of flue gas desulfurization and denitrification equipment, dust collectors are required to remove dust from the flue gas generated by these devices. Existing dust collectors typically use pressure transmitters to measure the pressure difference before and after dust removal, ensuring effective and stable dust collection. In actual operation, the pressure transmitter is usually connected directly from the pressure measurement point inside the dust collector's chamber via a straight pipe. However, due to the high temperature of the flue gas inside the chamber and the significant temperature difference with the outside, condensation frequently occurs in the pipes transmitting the signal to the pressure transmitter. This causes a pressure difference between the two ends of the pipe, resulting in a large error between the actual pressure inside the dust collector chamber and the pressure detected by the pressure transmitter, affecting the accuracy of the measurement. Utility Model Content

[0003] The main purpose of this invention is to propose an anti-condensation pressure transmission structure and a dust collector, which aims to prevent condensate in the pipeline from affecting the detection of the pressure transmitter.

[0004] To achieve the above objectives, the present invention proposes an anti-condensation pressure transmission structure, comprising:

[0005] An input pipe, the input pipe including an axial first end and a second end, the first end being used to communicate with a dust collector;

[0006] The output tube includes an axial third end and a fourth end, the fourth end being used to connect to a pressure transmitter;

[0007] A first connecting pipe, wherein the two ends of the first connecting pipe are respectively connected to the second end and the third end in the axial direction, and at least a portion of the first connecting pipe is higher than the input pipe and the output pipe; and

[0008] The second connecting pipe has its two ends axially connected to the two ends of the first connecting pipe, and also connected to the second end and the third end. The second connecting pipe is lower than the input pipe.

[0009] In one embodiment, the input pipe gradually decreases in the direction away from the dust collector, and the output pipe gradually increases in the direction closer to the pressure transmitter.

[0010] In one embodiment, the first connecting pipe has an inverted U-shaped structure, and the second connecting pipe has a U-shaped structure.

[0011] In one embodiment, the angle formed by the connection between the input tube and the first connecting tube is α, where 30° ≤ α ≤ 60°, and the angle formed by the connection between the output tube and the second connecting tube is β, where 30° ≤ β ≤ 60°.

[0012] In one embodiment, the input tube, the output tube, the first connecting tube, and the second connecting tube are an integral structure.

[0013] In one embodiment, a drain pipe is connected to the bottom of the second connecting pipe, and a control valve is connected to the drain pipe.

[0014] In one embodiment, the first connecting pipe and the second connecting pipe are connected by a quick connector to achieve a detachable connection.

[0015] In one embodiment, the input pipe, the output pipe, and the first connecting pipe are stainless steel pipes, and the second connecting pipe is a transparent flexible tube.

[0016] This utility model also proposes a dust collector, which includes an anti-condensation pressure transmission structure, the anti-condensation pressure transmission structure comprising:

[0017] An input pipe, the input pipe including an axial first end and a second end, the first end being used to communicate with a dust collector;

[0018] The output tube includes an axial third end and a fourth end, the fourth end being used to connect to a pressure transmitter;

[0019] A first connecting pipe, wherein the two ends of the first connecting pipe are respectively connected to the second end and the third end in the axial direction, and at least a portion of the first connecting pipe is higher than the input pipe and the output pipe; and

[0020] The second connecting pipe has its two ends axially connected to the two ends of the first connecting pipe, and also connected to the second end and the third end. The second connecting pipe is lower than the input pipe.

[0021] The technical solution of this utility model is to set a first connecting pipe and a second connecting pipe between the input pipe and the output pipe, and the height of the input pipe, the output pipe and the first connecting pipe is higher than the second connecting pipe. In this way, when condensation water forms inside the anti-condensation pressure transmission structure, the water flows into the second connecting pipe under the action of gravity, while the first connecting pipe above can still ensure the normal flow of gas, so that the pressure in the input pipe and the output pipe is basically the same, thereby ensuring the accuracy of the pressure transmitter's detection results.

[0031] During the operation of flue gas desulfurization and denitrification equipment, dust collectors are required to remove dust from the flue gas generated by these devices. Existing dust collectors typically use pressure transmitters to measure the pressure difference before and after dust removal, ensuring effective and stable dust collection. In actual operation, the pressure transmitter is usually connected directly from the pressure measurement point inside the dust collector's chamber via a straight pipe. However, due to the high temperature of the flue gas inside the chamber and the significant temperature difference with the outside, condensation frequently occurs in the pipes transmitting the signal to the pressure transmitter. This causes a pressure difference between the two ends of the pipe, resulting in a large error between the actual pressure inside the dust collector chamber and the pressure detected by the pressure transmitter, affecting the accuracy of the measurement.

[0032] To solve the above problems, please refer to Figure 1 and Figure 2 This utility model proposes an anti-condensation pressure transmission structure 1000, including an input pipe 1, an output pipe 2, a first connecting pipe 3, and a second connecting pipe 4. The input pipe 1 includes an axial first end 11 and a second end 12, with the first end 11 used to connect to a dust collector. The output pipe 2 includes an axial third end 21 and a fourth end 22, with the fourth end 22 used to connect to a pressure transmitter. The two ends of the first connecting pipe 3 are respectively connected to the second end 12 and the third end 21, and at least part of the structure of the first connecting pipe 3 is higher than the input pipe 1 and the output pipe 2. The two ends of the second connecting pipe 4 are respectively connected to the two ends of the first connecting pipe 3 and respectively connected to the second end 12 and the third end 21, with the second connecting pipe 4 being lower than the input pipe 1.

[0033] The technical solution of this utility model is to set a first connecting pipe 3 and a second connecting pipe 4 between the input pipe 1 and the output pipe 2, and the height of the input pipe 1, the output pipe 2 and the first connecting pipe 3 is higher than that of the second connecting pipe 4. In this way, when condensation water forms inside the anti-condensation pressure transmission structure 1000, the water flows into the second connecting pipe 4 under the action of gravity, while the first connecting pipe 3 above can still ensure the normal flow of gas, so that the pressure in the input pipe 1 and the output pipe 2 is basically the same, thereby ensuring the accuracy of the detection results of the pressure transmitter.

[0034] In an optional embodiment, to facilitate the flow of condensate into the second connecting pipe 4, the input pipe 1 gradually decreases in the direction away from the dust collector, while the output pipe 2 gradually increases in the direction closer to the pressure transmitter. This allows condensate to flow into the second connecting pipe 4 immediately when it appears in the anti-condensation pressure transmission structure 1000, preventing it from affecting the connection between the upper input pipe 1, output pipe 2, and the first connecting pipe 3, and also preventing backflow of condensate, thus ensuring the stability of the anti-condensation pressure transmission structure 1000. Optionally, the input pipe 1 and output pipe 2 can be straight pipes or bends with a certain curvature, depending on actual needs. This design utilizes the principle of gravity, which helps the condensate flow naturally and reduces stagnation in the pipes. This structural optimization not only helps reduce the potential damage of condensate to the pressure transmitter but also reduces pipe blockage and inaccurate pressure signal transmission caused by condensate accumulation. Furthermore, this design simplifies the condensate drainage process, as the condensate can naturally flow to lower areas for centralized treatment and discharge.

[0035] In an optional embodiment, to prevent cooling water from stagnating in the first connecting pipe 3, please refer to... Figure 1 and Figure 2 The first connecting pipe 3 has an inverted U-shape, and the second connecting pipe 4 has a U-shape. This design optimizes the flow path of condensate, allowing it to flow more smoothly from the inlet pipe 1 into the second connecting pipe 4. Even if condensation occurs on the inner walls of the first connecting pipe 3 and the outlet pipe 2 due to temperature differences, it can flow into the lower second pipe immediately, reducing stagnation in the piping system. The combination of the inverted U-shaped first connecting pipe 3 and the U-shaped second connecting pipe 4 forms an effective condensate collection system, helping to reduce pressure differences between the inlet pipe 1 and the outlet pipe 2 caused by condensate accumulation, thereby improving the reliability of pressure detection throughout the dust removal system.

[0036] In an alternative embodiment, please refer to Figure 1 and Figure 2The angle between the connection points of the inlet pipe 1 and the first connecting pipe 3 is 'a', where 30° ≤ a ≤ 60°, and the angle between the connection points of the outlet pipe 2 and the second connecting pipe 4 is 'b', where 30° ≤ b ≤ 60°. This angle design helps balance the flow of condensate and the stability of the pipeline. If the angle is too small, condensate may flow poorly and accumulate at the connection points; if the angle is too large, it may affect the stability and structural strength of the pipeline. Therefore, by controlling the angle between 30° and 60°, it is possible to ensure smooth flow of condensate while maintaining the stability of the pipeline structure, reducing equipment failures that may be caused by condensate accumulation, and improving the reliability and stability of the entire system.

[0037] In an optional embodiment, the input pipe 1, output pipe 2, first connecting pipe 3, and second connecting pipe 4 are integrated into a single unit. This integrated design simplifies the assembly process of the entire system and reduces the risk of leakage that may arise from connecting multiple independent components. Since all pipes and connections are manufactured and installed as a single unit, precise fit between components is ensured, reducing installation errors and improving the system's sealing and durability. Furthermore, the integrated structure helps reduce maintenance work, as no part of the system requires individual disassembly and replacement, reducing maintenance costs and downtime. In practical applications, this design can improve system stability and reliability, reducing the risk of failure due to improper connections or component aging.

[0038] In another alternative embodiment, the first connecting pipe 3 and the second connecting pipe 4 are detachably connected using a quick connector 6. The quick connector 6 provides a fast and easy way to connect and disconnect, making maintenance and component replacement more efficient. The use of the quick connector 6 reduces the time and labor required by traditional fixed connection methods, while also reducing the risk of system damage due to improper maintenance. This detachable connection design allows operators to respond quickly when pipe replacement or repair is needed, reducing system downtime and improving the availability and maintenance efficiency of the entire dust removal system. Furthermore, the detachable design of the second connecting pipe 4 allows for removal of ice if condensation occurs inside the pipe due to low temperatures, ensuring sufficient water storage space within the pipe and guaranteeing the effectiveness and stability of the anti-condensation pressure transmission structure 1000.

[0039] In an optional embodiment, to facilitate the drainage of condensate from the second connecting pipe 4, please refer to... Figure 2The bottom of the second connecting pipe 4 is connected to a drain pipe 5, and a control valve is connected to the drain pipe 5. This design allows the anti-condensation pressure transmission structure 1000 to actively drain accumulated condensate. By adjusting the control valve, the operator can control the drainage speed and time according to the actual situation, which provides the system with greater flexibility and controllability. The design of the drain pipe 5 helps prevent condensate from accumulating in the system, thereby reducing equipment corrosion and pressure signal errors caused by condensate. This active drainage design improves the safety and accuracy of the system, ensuring the accuracy of the pressure transmitter and the efficient operation of the dust collector. Optionally, the control valve can be a manually controlled valve or a solenoid valve, whichever is more suitable for actual needs.

[0040] In an optional embodiment, the input pipe 1, output pipe 2, and first connecting pipe 3 are stainless steel pipes, while the second connecting pipe 4 is a transparent flexible tube. The first connecting pipe 3 needs to circulate the gas after dust removal treatment. This gas may contain small amounts of residual harmful gases or impurities. Stainless steel pipes, due to their corrosion resistance and strength, are suitable for withstanding pressure and chemical media erosion, thus ensuring their service life. The second connecting pipe 4 is mainly used to store and discharge condensate, while the transparent flexible tube facilitates monitoring the state of the condensate within the pipe, allowing for timely detection and handling of potential problems. Furthermore, the cost of the transparent flexible tube is lower than that of stainless steel pipes, and it is easy to disassemble and replace. Optionally, the transparent flexible tube can be a plastic or rubber tube. This combination of materials not only improves the durability and reliability of the system but also enhances its safety, allowing operators to visually observe the flow of condensate through the transparent flexible tube and take timely measures to prevent potential problems.

[0041] This utility model also proposes a dust collector, which includes an anti-condensation pressure transmission structure 1000. The specific structure of the anti-condensation pressure transmission structure 1000 is as described in the above embodiments. By integrating the anti-condensation pressure transmission structure 1000, the reliability and accuracy of the pressure transmitter's pressure detection are ensured. This guarantees the normal operation of the dust collector, enabling it to not only effectively remove dust but also maintain the accuracy of the pressure signal while reducing malfunctions and maintenance problems caused by condensation. Since this dust collector adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0042] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
