Description

Technical Field

[0001] The present invention belongs to the technical field of material sampling inspection equipment, and in particular relates to a detachable three-point monitoring auxiliary device for a boiler and a use method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the actual implementation and operation of boiler furnace flue gas temperature measurement, the long measuring tubes, which make routing difficult and the difficulty in observing the temperature measurement points at different depths, have always been factors that plague furnace temperature measurement and monitoring in power plants. Traditional boiler furnace flue gas temperature measurement, due to the lack of a corresponding length measurement standard line, can easily cause the temperature measurement point to deviate from the actual measurement point, resulting in measurement errors. For example, during routine measurements, the actual temperature measurement point constantly moves around the actual temperature measurement point due to manual insertion of the tube, causing its position to deviate and cause errors. Furthermore, long-term measurements can cause the measuring tube to sag due to its own weight, resulting in bending. This not only introduces greater errors in the next measurement, but also shortens the life of the measuring tube, increasing costs.

[0004] In existing equipment, boiler furnace flue gas temperature measurement usually involves drawing lines on a long duct to determine the distance between each temperature measurement point. However, this old measurement method has certain limitations: the measuring tube is too long, making it difficult to route the lines for each measurement in the narrow measuring duct, and it is difficult to transmit the lines from the entrance to the measurement end. At the same time, a single measuring duct is too long to be easily carried.

[0005] Secondly, when measuring three or more temperature points, adjusting the length of the line not only increases the operation time, but also increases the possibility of operational errors. Summary of the Invention

[0006] To address the above-mentioned issues, the present invention provides a detachable three-point monitoring auxiliary device for boilers and a method for use, which reduces the errors and time consumption caused by multiple measurements, provides guide tubes of different lengths to adapt to the complex spatial structure within the furnace, and reduces errors or risks that may be introduced during operation.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0009] Further, the fixed disk is composed of a first fixed disk, a second fixed disk, and a third fixed disk. The first fixed disk is fixedly arranged at the top of the third upper section conduit and the middle of the first upper section conduit; the second fixed disk is arranged at the bottoms of the third upper section conduit and the first upper section conduit; the fourth fixed disk is arranged at the tops of the first lower section conduit, the second conduit, and the third lower section conduit.

[0011] Further, the first conduit, the second conduit, and the third conduit are all hollow conduits, and the length of the first conduit is greater than the length of the third conduit, and the length of the third conduit is greater than the length of the second conduit.

[0012] Further, the bottom ends of the first upper section conduit, the first lower section conduit, the third upper section conduit, and the third lower section conduit are each provided with an external fitting conduit; the top ends of the first upper section conduit, the first lower section conduit, the third upper section conduit, and the third lower section conduit are each provided with an embedded fitting conduit; the lengths of the first lower section conduit, the third lower section conduit, and the second conduit are equal, and the length of the first upper section conduit is greater than the length of the third upper section conduit.

[0013] Further, the outer side wall of the embedded fitting conduit is provided with an external thread, and the inner side wall of the external fitting conduit is provided with an internal thread, and the parameters of the internal thread and the external thread are the same.

[0014] Further, the diameters of the three through holes on the first fixing disk, the second fixing disk, and the third fixing disk are larger than the diameters of the first conduit, the second conduit, and the third conduit, and friction dampers are provided in all three through holes for fixing the first conduit, the second conduit, and the third conduit to prevent movement between the fixing disks and the conduits.

[0015] Further, temperature monitoring sensors are installed on the inner fitting conduits at the tops of the first conduit, the second conduit, and the third conduit, and signal lines are arranged in the corresponding conduits for connecting to a monitoring terminal to achieve temperature monitoring at different spatial positions.

[0016] Further, alternatively, a breathing valve is installed on the inner fitting conduit at the top of the first conduit, the second conduit, and the third conduit, and an air suction device is connected to the outer fitting conduits at the bottoms of the first conduit, the second conduit, and the third conduit for collecting gas parameters at different spatial positions.

[0017] In a second aspect, the present invention also provides a method for using a detachable three-point monitoring auxiliary device for a boiler, including the following steps:

[0018] S1. According to the actual measurement requirements, using the threaded connection characteristics of the inner fitting conduit and the outer fitting conduit, splice the first upper conduit and the first lower conduit, and splice the third upper conduit and the third lower conduit; insert the upper halves of the first lower conduit, the second conduit, and the third lower conduit into the friction dampers of the through holes of the third fixing disk to achieve fixed connection, insert the upper halves of the first upper conduit and the third upper conduit into the friction dampers of the through holes of the first fixing disk, and insert the lower halves of the first upper conduit and the third upper conduit into the friction dampers of the through holes of the second fixing disk;

[0019] S2. When performing temperature monitoring, install temperature monitoring sensors on the inner fitting conduits at the tops of the first conduit, the second conduit, and the third conduit, and arrange signal lines in the corresponding conduits to connect to the monitoring terminal;

[0020] When performing gas collection, install a breathing valve on the inner fitting conduit at the top of the first conduit, the second conduit, and the third conduit, and connect an air suction device to the outer fitting conduits at the bottoms of the first conduit, the second conduit, and the third conduit; when the air suction device operates, the gas at different spatial positions in the furnace is sucked into the air suction device through the conduits under the action of the breathing valve;

[0021] S3. After all components are installed, smoothly insert the auxiliary device at the wall opening of the furnace water wall until the bottom large disk at the lowermost end fits against the outer wall surface of the wall opening of the water wall; then start the monitoring device to start monitoring the temperature or gas parameters at the corresponding points;

[0022] S4. After the measurement, the entire measuring device is withdrawn for maintenance; if temperature measurement monitoring is carried out, the following steps need to be continued. The three signal lines are withdrawn and separated in the corresponding conduits, and the first upper conduit and the third upper conduit are withdrawn for maintenance in sequence for future use.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0024] The first conduit and the third conduit of the present invention adopt a segmented design, and the lengths of the first conduit, the second conduit, and the third conduit are different. Through one-time installation and measurement, data of multiple key positions in the furnace can be obtained, improving work efficiency and reducing errors and time consumption caused by multiple measurements. At the same time, the conduits of different lengths also adapt to the complex spatial structure in the furnace and can more comprehensively reflect the distribution of physical parameters in the furnace. The addition of a simple installation and disassembly process makes the use of tools more convenient and flexible, reduces operation time, and also reduces errors or risks that may be introduced during the operation. When in need of use, as long as the two corresponding fitting ports are fitted correspondingly, three complete different conduits can be formed to measure the temperature at the corresponding temperature measurement points, and at the same time, maintenance and overhaul are made easier, improving maintenance efficiency and reducing maintenance costs.

[0025] In the present invention, the first conduit, the second conduit, and the third conduit are connected to form a whole through welding discs, making the structure more firm and not easily affected by the movement of other substances in the monitoring space to affect its stability. The fixing discs at three different positions reduce the cantilever beam arm lengths of the two conduits. The structure in which the first conduit, the second conduit, and the third conduit are distributed in an equilateral triangle has good stability and can more reliably protect measuring devices such as thermocouples in the complex high-temperature, high-pressure, vibration and other environments in the boiler furnace. Compared with the old-fashioned single conduit, the practicability and service life have been greatly improved, which has brought great changes to cost reduction and measurement result accuracy improvement.

[0026] The present invention is not only applicable to the temperature measurement of boilers, but also can install corresponding measuring instruments according to needs to measure the oxygen concentration, flue gas flow rate, etc. at the corresponding points, and at the same time provides a new idea for the insertion-type measuring device, with broad application prospects and market value.

[0035] Embodiment 1

[0036] This embodiment provides a detachable three-point monitoring auxiliary device for a boiler, as Figures 1-4 shown, including: the first conduit 1, the second conduit 2, and the third conduit 3 with different lengths, and the fixed disk and the sealing installation disk 7; one end of the first conduit 1, the second conduit 2, and the third conduit 3 is provided with an end embedded fitting conduit 8 for splicing the conduits and installing monitoring sensors, and the other end is provided with an end external fitting conduit 11 for splicing the conduits; both the first conduit 1 and the third conduit 3 are composed of two parts, the first conduit 1 includes a first upper section conduit and a first lower section conduit, the third conduit 3 includes a third upper section conduit and a third lower section conduit, and the sealing installation disk 7 is fixed at the bottom of the first lower section conduit, the second conduit 2, and the third lower section conduit; the upper halves of the first conduit 1, the second conduit 2, and the third conduit 3 are fixedly connected to the fixed disk, and the tops of the first conduit 1, the second conduit 2, and the third conduit 3 are at different heights for measuring the measurement indexes at different positions in the monitoring space.

[0037] The first conduit 1 and the third conduit 3 adopt a segmented design, that is, the first conduit 1 is divided into a first upper conduit and a first lower conduit, and the third conduit 3 is divided into a third upper conduit and a third lower conduit. A middle externally fitted conduit 9 is provided at the bottom ends of the first upper conduit and the third upper conduit, and a middle internally fitted conduit 10 is provided at the top ends of the first lower conduit and the third lower conduit. Each section of the conduit is spliced by the threaded connection of the middle internally fitted conduit 10 and the middle externally fitted conduit 9. This modular structural design makes the device more convenient during transportation and installation, facilitating carrying and operation. At the same time, when maintaining or replacing components, only the corresponding conduit section needs to be disassembled and replaced, without the need for overall replacement, greatly reducing the maintenance cost and time cost.

[0038] Furthermore, the fixing plate is composed of a first fixing plate 4, a second fixing plate 5, and a third fixing plate 6. The first fixing plate 4 is fixedly arranged at the top of the third upper conduit and the middle of the first upper conduit; the second fixing plate 5 is arranged at the bottom of the third upper conduit and the first upper conduit; the fourth fixing plate is arranged at the top of the first lower conduit, the second conduit 2, and the third lower conduit.

[0039] Furthermore, the first fixing plate 4, the second fixing plate 5, and the third fixing plate 6 are all provided with three through holes 12, and the center distances of the three through holes 12 are the same; the sealing mounting plate 7 is also provided with three through holes 12, and the center distances of the three through holes 12 are the same; so that the first conduit 1, the second conduit 2, and the third conduit 3 are inserted into the through holes 12 of the fixing plate in an equilateral triangle distribution.

[0040] Furthermore, the first conduit 1, the second conduit 2, and the third conduit 3 are all hollow conduits, which is convenient for threading signal transmission lines, reducing the wiring difficulty of the entire conduit, and facilitating providing a transmission channel for gas when collecting gas. And the length of the first conduit 1 is greater than the length of the third conduit 3, and the length of the third conduit 3 is greater than the length of the second conduit 2, so that the measurement indexes of three corresponding measurement points can be measured simultaneously; through one installation and measurement, data of multiple key positions in the furnace can be obtained, improving work efficiency and reducing errors and time consumption caused by multiple measurements. At the same time, the conduits of different lengths also adapt to the complex spatial structure in the furnace and can more comprehensively reflect the distribution of physical parameters in the furnace.

[0042] Further, external threads are provided on the outer side walls of the inner inlay conduits, internal threads are provided on the inner side walls of the outer inlay conduits, and the parameters of the internal threads are the same as those of the external threads.

[0043] Further, the diameters of the three through holes 12 in the first fixing plate 4, the second fixing plate 5, and the third fixing plate 6 are greater than the diameters of the first conduit 1, the second conduit 2, and the third conduit 3, and friction dampers 13 are provided in the three through holes 12 for fixing the first conduit 1, the second conduit 2, and the third conduit 3 to prevent movement between the fixing plates and the conduits; the provision of the friction dampers 13 further enhances the connection firmness between the conduits and the fixing plates and reduces measurement deviations caused by external factors.

[0044] Further, temperature monitoring sensors are installed on the inner inlay conduits at the top ends of the first conduit 1, the second conduit 2, and the third conduit 3, and signal lines are arranged in the corresponding conduits for connecting to a monitoring terminal to realize temperature monitoring at different spatial positions. Since the three conduits are all hollow conduits, this structural design has multiple advantages, facilitating the threading of signal transmission lines, enabling the signal lines of the temperature monitoring sensors to be successfully arranged and connected to the monitoring terminal, reducing the wiring difficulty of the entire device, and improving the stability and reliability of signal transmission.

[0045] Further, alternatively, breathing valves are installed on the inner inlay conduits at the top ends of the first conduit 1, the second conduit 2, and the third conduit 3, and suction devices are connected and provided on the outer inlay conduits at the bottom ends of the first conduit 1, the second conduit 2, and the third conduit 3 for collecting gas parameters at different spatial positions. The three conduits are all hollow conduits. When collecting gas, the hollow conduits provide a transmission channel for the gas, enabling the suction devices to successfully collect the gas at different spatial positions in the furnace, providing convenient conditions for the analysis and measurement of gas parameters.

[0049] S2.

According to the analysis results, the operator can evaluate and adjust the operating state of the boiler furnace to ensure the safe and efficient operation of the boiler.

[0051] S3. After all components are installed, smoothly insert this auxiliary device at the wall opening of the furnace water-cooled wall until the bottom large disc at the lowermost end fits against the outer wall surface of the wall opening of the water-cooled wall; then start the monitoring device to begin monitoring the temperature or gas parameters at the corresponding points;

Withdraw and separate the three signal lines in the corresponding conduits, and withdraw and maintain the first upper-section conduit and the third upper-section conduit in sequence for future use.

[0053] Although the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solution of the present invention are still within the protection scope of the present invention.
