Description
Technical Field
[0001] This invention relates to the field of furnace temperature detection technology, specifically to an intelligent sensor for detecting furnace temperature. Background Technology
[0002] Furnace temperature monitoring is one of the core monitoring links for the operation of industrial furnaces, boilers, incinerators and other equipment. Its core purpose is to ensure equipment safety, optimize combustion efficiency and control process quality.
[0003] Intelligent sensors for detecting furnace temperature mainly include thermocouple sensors, resistance temperature detectors (RTDs), infrared temperature sensors, and acoustic temperature sensors. When using an infrared temperature sensor to detect the internal temperature of the furnace, the built-in infrared detector receives the infrared radiation from the target inside the furnace, converts the radiation energy into an electrical signal, and calculates the temperature value using an algorithm. During the detection process, the combustion temperature inside the furnace can reach 800-1800℃. Ash (such as SiO2 and Al2O3) and unburned carbon particles in fuels such as coal and biomass are in a molten or semi-molten state at high temperatures. When they flow with the flue gas, if they come into contact with the relatively low-temperature sensor front end (lens, protective window), they will cool and solidify rapidly, forming an initial coke layer, which affects the normal use of the subsequent infrared detector. Therefore, we propose an intelligent sensor for detecting furnace temperature. Summary of the Invention

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0019] Please see Figures 1-11 The figure shows an intelligent sensor for detecting furnace temperature, including a temperature sensor for intelligently measuring the temperature inside the furnace by infrared sensing. The temperature sensor includes a mounting sleeve 101, which has a front end and a rear end. The front and rear ends of the mounting sleeve 101 are respectively provided with quartz glass 103 for auxiliary heat insulation and infrared sensor 102 for auxiliary detection. It should be noted here that: the infrared sensor 102 is used to detect the internal temperature of the furnace. High-temperature targets such as flames and furnace walls inside the furnace will emit infrared radiation energy outward according to the Stefan-Boltzmann law. The optical lens at the front end of the infrared sensor 102 focuses the infrared radiation of the target. After penetrating the protective window of the quartz glass 103, it is captured by the infrared sensor 102, which converts the radiation energy into a weak electrical signal. After the electrical signal is amplified, filtered, and converted from analog to digital, the microprocessor, combined with emissivity compensation and environmental compensation algorithms, converts it into a precise temperature value, thereby realizing intelligent detection of the internal temperature of the furnace. In addition, the infrared sensor 102 is used as a conventional technical means in this application, and its working principle and operation method will not be described in detail here.
[0020] Also includes: A descaling component is installed at the front end of the mounting sleeve 101 for descaling protection during the testing process. A water-cooling component is installed inside the mounting sleeve 101 for water cooling during the testing process. The purging assembly is located at the front end of the mounting sleeve 101 and is used to purge the coke residue on the decoking assembly and the quartz glass 103 after detection. The mounting sleeve 101 is equipped with a scraping assembly for assisting in scraping the residue. And, a drive assembly located on the outside of the furnace body for driving the mounting sleeve 101; It should be noted that when using an infrared temperature sensor to detect the temperature inside the furnace, the configuration of components such as the descaling assembly, the purging assembly, and the scraping assembly can reduce the probability of flue gas directly contacting the quartz glass 103 and forming a slag layer on the quartz glass 103. It can also facilitate the subsequent cleaning and slag removal of the quartz glass 103, making it easier to perform efficient and stable furnace temperature detection operations.
[0021] Preferably, the decoking assembly includes a mounting cylinder 201 fixed to the front end of the mounting sleeve 101, a decoking tube 202 fixed to the front end of the mounting cylinder 201, and a decoking tube 203 rotatably connected inside the mounting cylinder 201 and the decoking tube 202 via a rotating assembly. It should be noted that, due to the installation of the front mounting cylinder 201 and the coke removal tube 202 on the quartz glass 103, the flue gas entering the coke removal tube 202, under the influence of the coke attachment cylinder 203 inside the coke removal tube 202 and the setting of the length of the coke attachment cylinder 203 itself, allows the flue gas to cool and solidify rapidly on the inner wall of the coke attachment cylinder 203 after entering the coke attachment cylinder 203, forming an initial coke layer. This reduces the probability of the flue gas directly contacting the quartz glass 103 and forming a coke layer on the quartz glass 103, thus facilitating the use of the quartz glass 103.
[0022] Preferably, the purging assembly includes an air blowing pipe 501 that is connected to the mounting cylinder 201. One end of the air blowing pipe 501 is connected to an external high-pressure air blowing device. A retaining ring 502 is fixed on the outside of the coking cylinder 203. The space between the coking cylinder 203 and the mounting cylinder 201 is a mounting cavity of a different shape. The mounting cavity is divided by the retaining ring 502 to form a first chamber and a second chamber. The air blowing pipe 501 is connected to the inside of the second chamber. The inside of the second chamber is fixed with multiple sets of inclined plates 503 in a ring array. The inclined plates 503 are fixed on the outside of the coking cylinder 203. It should be noted here that: through the driving action of the external high-pressure blowing equipment and the connection action of the blowing pipe 501, high-pressure gas enters the interior of the mounting cavity. After entering, part of the gas passes through the surface of the quartz glass 103 and the inner side of the coking cylinder 203 and is discharged outward. In addition, the high-pressure air blowing equipment is a conventional technical component in this application. Its working principle and the way it is installed and connected with the air blowing pipe 501 are well-known technologies and will not be described in detail here.
[0023] Preferably, the scraping assembly includes a mounting plate 601 disposed inside the coking cylinder 203, a connecting assembly for auxiliary connection is disposed between the mounting plate 601 and the inner wall of the coking cylinder 203, a mounting block 602 is disposed on one side of the mounting plate 601, an L-shaped scraper 603 is fixed on the mounting block 602, an elastic assembly for auxiliary elastic pushing is disposed between the mounting plate 601 and the mounting block 602, and one side of the L-shaped scraper 603 is abutted against the outer side of the quartz glass 103 under the elastic force of the elastic assembly; It should be noted that during the entry of high-pressure gas, the interaction between the high-pressure gas and each set of inclined plates 503 drives the coking cylinder 203 to move under force. During the movement of the coking cylinder 203, the rotation of the rotating component causes the coking cylinder 203 to rotate inside the mounting cylinder 201. The rotation of the coking cylinder 203 facilitates the separation of the coke residue attached to it. During the rotation of the coking cylinder 203, the L-shaped scraper 603 rotates synchronously through the connection of the connecting component, the guiding component, and the elastic component. Since the L-shaped scraper 603 abuts against the surface of the quartz glass 103, the rotation of the L-shaped scraper 603 scrapes and cleans the coke residue on the surface of the quartz glass 103.
[0024] Preferably, the elastic component includes multiple sets of sleeves 701 fixed on the mounting plate 601, a slide rod 702 slidably connected on the sleeve 701, one end of the slide rod 702 being fixed to the mounting block 602, and a first spring 703 being sleeved on the outside of the sleeve 701, with both ends of the first spring 703 abutting against the mounting plate 601 and the mounting block 602 respectively. It should be noted that: the multiple sets of sleeves 701 and slide rods 702 facilitate the telescopic guidance between the mounting plate 601 and the mounting block 602, and the first spring 703 facilitates the elastic pushing of the L-shaped scraper 603 on the mounting block 602.
[0025] Preferably, the connecting assembly includes a mounting frame 801 fixed inside the coking cylinder 203, a sliding plate 802 connected to the mounting frame 801 via a guide assembly, a connecting rod 803 fixed between the sliding plate 802 and the mounting plate 601, and the connecting rod 803 slidably connected to the mounting frame 801. It should be noted here that the mounting frame 801, the sliding plate 802, and the connecting rod 803 facilitate auxiliary connection.
[0026] Preferably, the guide assembly includes multiple sets of guide rods 901 slidably connected to the slide plate 802, the guide rods 901 are fixed to the mounting frame 801, and a second spring 902 is sleeved on the outer side of the guide rods 901; It should be noted that: multiple sets of guide rods 901 facilitate the movement guidance of the sliding plate 802, and multiple sets of second springs 902 facilitate the reset of the sliding plate 802 after movement.
[0027] Preferably, the rotating assembly includes an annular groove 401 formed on the inner wall of the mounting cylinder 201, an annular bar 402 slidably connected to the annular groove 401, the annular bar 402 being fixed to the coking cylinder 203, and the mounting cylinder 201, the annular groove 401, the annular bar 402 and the coking cylinder 203 being concentrically arranged. It should be noted here that the annular groove 401 and the annular bar 402 facilitate the rotation of the coke cylinder 203 after being subjected to force.
[0028] Preferably, the water-cooling assembly includes a water-cooling pipe 301 disposed inside the first chamber. The water-cooling pipe 301 is arranged in a spiral shape. The coking cylinder 203 has multiple sets of slots 302 for auxiliary communication. The two ends of the water-cooling pipe 301 are located outside the mounting cylinder 201 and are respectively fixed with an inlet pipe 303 and an outlet pipe 304. It should be noted here that during the temperature detection process, the water inlet pipe 303 and water outlet pipe 304 on the water-cooling component are respectively connected to the water inlet and water outlet of the external water-cooling circulation equipment. Through the driving action of the water-cooling circulation equipment, the coolant flows through the water-cooling pipe 301. During the flow, the generated cold air enters the interior of the mounting cylinder 201 through each set of slots 302 to cool down the quartz glass 103 during the temperature measurement process, so as to avoid the high temperature inside the furnace body from affecting the quartz glass 103 and causing it to deform. In addition, the water-cooled circulation equipment is a conventional technical component in this application. Its working principle and the connection method with the inlet pipe 303 and the outlet pipe 304 are known technologies in this application and will not be described in detail here.
[0029] Preferably, the drive assembly includes a mounting base 1001, an annular mounting platform 1002 fixed on the mounting base 1001, a mounting sleeve 101 detachably mounted on the annular mounting platform 1002 by means of threads, a mounting base plate 1003 mounted on the outside of the furnace body by means of threads, a drive frame 1004 fixed on the mounting base plate 1003, a threaded sleeve 1005 fixed on the mounting base 1001, a lead screw 1006 rotatably connected to the drive frame 1004, the threaded sleeve 1005 and the lead screw 1006 being meshed with each other, a drive motor 1007 for driving the lead screw 1006 being mounted on the outside of the drive frame 1004, a plurality of mounting rods 1008 slidably connected on the mounting base 1001, the mounting rods 1008 being fixed on the drive frame 1004, a wind hood 1009 for communicating with the inside of the furnace body being provided on the mounting base plate 1003, and a coke removal pipe 202 being slidably connected to the wind hood 1009; It should be noted that: the drive motor 1007 drives the lead screw 1006 to rotate. During the rotation of the lead screw 1006, the mutual meshing transmission between the lead screw 1006 and the threaded sleeve 1005 and the sliding guidance of multiple sets of mounting rods 1008 cause the mounting seat 1001 to move under force. The movement of the mounting seat 1001 drives the mounting sleeve 101 installed on the annular mounting platform 1002 to move synchronously. The movement of the mounting sleeve 101 facilitates the control of the decoking pipe 202 extending into or sliding out of the furnace body.
[0030] In this solution: a smart sensor for detecting furnace temperature includes the following steps: When using an infrared temperature sensor to detect the internal temperature of the furnace, the mounting sleeve 101 is threaded onto the annular mounting platform 1002 of the mounting base 1001. During installation, the descaling tube 202 on the front mounting cylinder 201 of the mounting sleeve 101 is positioned in front of the quartz glass 103. The mounting base plate 1003 is then threaded onto the outside of the furnace body. After installation, the rotation of the lead screw 1006 drives the mounting base 1001 and the mounting sleeve 101 mounted on it to move towards the furnace body. During this movement, the descaling tube 202 on the front of the mounting sleeve 101 is propelled by air... The shroud 1009 passes through and extends into the interior of the furnace body. After the drive is completed, the infrared sensor 102 is used to detect the temperature inside the furnace. High-temperature targets such as flames and furnace walls inside the furnace will emit infrared radiation energy outward according to the Stefan-Boltzmann law. The optical lens at the front end of the infrared sensor 102 focuses the infrared radiation of the target. After penetrating the protective window of the quartz glass 103, it is captured by the infrared sensor 102, which converts the radiation energy into a weak electrical signal. After the electrical signal is amplified, filtered, and converted from analog to digital, the microprocessor, combined with emissivity compensation and environmental compensation algorithms, converts it into a precise temperature value, thereby realizing intelligent detection of the temperature inside the furnace body. During temperature detection, the inlet pipe 303 and outlet pipe 304 of the water-cooling assembly are connected to the inlet and outlet of the external water-cooling circulation equipment, respectively. Driven by the water-cooling circulation equipment, the coolant flows through the water-cooling pipe 301. During this flow, the generated cold air passes through the slots 302 and enters the interior of the mounting cylinder 201, cooling the quartz glass 103 during temperature measurement. This prevents the high temperature inside the furnace from affecting the quartz glass 103 and causing deformation, ensuring stable temperature detection. Furthermore, during temperature detection, the combustion temperature inside the furnace can reach 800-1800℃, and coal-fired... Ash and unburned carbon particles in fuels such as biomass are in a molten or semi-molten state at high temperatures and flow with the flue gas. During the flow, due to the installation of the cylinder 201 and the coke removal tube 202 on the front side of the quartz glass 103, the flue gas entering the coke removal tube 202 is rapidly cooled and solidified on the inner wall of the coke removal tube 203 by the action of the coke attachment tube 203 inside the coke removal tube 202 and the setting of the length of the coke attachment tube 203 itself, so that the flue gas enters the coke attachment tube 203 and is rapidly cooled and solidified on the inner wall of the coke attachment tube 203 to form an initial coke slag layer. This reduces the probability of the flue gas directly contacting the quartz glass 103 and forming a coke slag layer on the quartz glass 103, and facilitates the use of the quartz glass 103. As the testing process progresses, when it becomes necessary to remove the coke residue layer adhering to the inner wall of the coke attachment cylinder 203 and the surface of the quartz glass 103, the decoking pipe 202 is moved outward from the hood 1009 via a drive assembly. After movement, high-pressure gas is introduced into the mounting cavity by the drive of an external high-pressure blowing device and the connection of the blowing pipe 501. Part of the gas then passes through the surface of the quartz glass 103, through the inner side of the coke attachment cylinder 203, and is discharged outward (see...). Figure 11During the high-pressure gas flow, the coke residue adhering to the surface of the coke attachment cylinder 203 and the quartz glass 103 is carried away, achieving a cleaning effect. Additionally, during the entry of high-pressure gas, the interaction between the high-pressure gas and each set of inclined plates 503 drives the coke attachment cylinder 203 to move under force. During this movement, the rotation of the rotating assembly causes the coke attachment cylinder 203 to rotate inside the mounting cylinder 201. This rotation facilitates the separation of the coke residue adhering to the coke attachment cylinder 203. During the rotation of the coke attachment cylinder 203, the L-shaped scraper 603 rotates synchronously through the connection of the connecting assembly, guiding assembly, and elastic assembly. Because the L-shaped scraper 603 abuts against the surface of the quartz glass 103, its rotation cleans the quartz glass. The coke residue on the surface of the quartz glass 103 is scraped off and cleaned. In addition, with the rotation of the coke attachment cylinder 203, the slide plate 802, connecting rod 803 and mounting plate 601 move radially along the quartz glass 103 through the action of centrifugal force. During the movement, the L-shaped scraper 603 is driven to move radially while adhering to the surface of the quartz glass 103 through the connection of the elastic component. The radial movement and the rotation of the L-shaped scraper 603 facilitate the scraping and removal of residue from different positions on the quartz glass 103, ensuring the effect of residue removal. After cleaning, the L-shaped scraper 603 is radially reset under the elastic force of the second spring 902 on the guide component. The radial reset of the L-shaped scraper 603 avoids the L-shaped scraper 603 from obstructing the quartz glass 103, ensuring the effective temperature detection in the subsequent process.
