Description

Technical Field

[0001] The present invention relates to the technical field of thermometers, and in particular to an integrated coke cake thermometer and a method for using the same. Background Art

[0002] The coke cake center temperature is a key indicator of the uniform maturity of the coke. It is the combined result of the coke oven's horizontal and vertical heating processes. Its uniformity is a crucial indicator for evaluating the integrity of the coke oven's structure and heating system. By mapping the coke cake surface temperature curve to the horizontal rows of vertical flue holes, the coke cake surface temperature data can be used to determine which pairs of holes have low or high temperatures. This can be used to directly guide vertical flue temperature adjustments and simulate horizontal wall temperatures based on the coke cake surface temperature.

[0003] Therefore, it is very important to measure the surface temperature of coke cakes. The current methods for measuring the surface temperature of coke cakes are:

[0004] 1. During the coking process, use a handheld infrared thermometer to measure the coke cake temperature;

[0005] 2. At the initial stage of coal loading, a steel pipe is driven into the coal loading hole and a thermocouple is inserted into the steel pipe for measurement.

[0006] Location plan of temperature measurement points:

[0007] 2.1. Insert a pipe longitudinally at the coal loading port for measurement;

[0008] 2.2. Insert the pipe horizontally from the furnace door side.

[0009] The measured temperature points are the center temperatures of the coke cakes just below the coal loading ports on the machine and coke sides.

[0010] Open 50mm holes (or smaller holes depending on actual conditions) at the top, middle, and bottom of the furnace doors on the machine and coke sides. Select three seamless steel pipes with a diameter of approximately 30mm (smaller than the furnace door opening diameter) and a length of 3000mm (the pipe length is determined based on the center position of the coal loading port on the machine and coke sides). One end is open and the other end is closed. After the coke pushing operation in the carbonization chamber to be measured is completed, install the furnace door with the holes opened. After the coal loading operation is completed, insert the seamless steel pipes. After the coke cake is mature, insert a thermocouple into the seamless steel pipe to measure the center temperature of the coke cake.

[0011] 3. The temperature of the coke cake center is replaced by measuring the surface temperature of the coke cake side close to the furnace wall.

[0012] Methods 1 and 2 have drawbacks such as high labor intensity, harsh operating environment, poor representativeness, and difficulty in direct online measurement. Method 3 enables online automatic measurement of the coke cake center temperature. The side surface temperature of the coke cake near the furnace wall is 20-40°C higher than the center surface temperature, allowing the coke cake center temperature to be estimated in a timely manner.

[0013] The core component of the existing coke cake temperature measurement system is a split infrared fiber optic thermometer, which consists of three parts: an optical system, a high-temperature resistant quartz fiber, and a signal processing system. The optical system collects infrared light radiation (representing temperature) from the coke cake surface and transmits it to the instrument through optical fiber. The instrument system then converts the light radiation intensity into a temperature signal.

[0014] The existing split-type infrared fiber optic thermometer has the following disadvantages:

[0015] 1. The split structure of optical lens + optical fiber + signal processing is complex and inconvenient to install and maintain;

[0016] 2. Optical fiber is used to transmit optical signals to the signal processing device. Optical fiber is brittle and easy to break during installation;

[0017] 3. The temperature meter is installed on the focus guide grid of the focus intercepting vehicle. The focus guide grid needs to be extended and retracted during the focus guiding process, and the optical fiber is constantly bent and can easily break.

[0018] 4. The optical fiber transmission coefficients at different bending radii are different and cannot be calibrated and compensated, which affects the measurement accuracy;

[0019] 5. Optical fiber is a customized product that needs to be commissioned, which has a long cycle and high cost. Once damaged, production cannot be quickly restored;

[0020] 6. The split structure follows the vertical fire channel split temperature measurement solution, but the installation location of the optical part is not subject to long-term high temperature. It makes little sense to use the split structure to place the signal processing device far away. Summary of the Invention

[0030] Preferably, a method for using the integrated coke cake thermometer as described in any one of the above items comprises the following steps:

[0031] Step 1: Install one end of the peep tube on the inner side of the focus guide grid, with the end of the peep tube flush with the inner wall of the focus guide grid, and weld the other end of the peep tube to the outer wall of the focus guide grid;

[0032] Step 2: Connect the peep tube on the outer wall of the focus guide grid to one side of the photoelectric thermometer chamber;

[0033] Step 3: Install the photoelectric thermometer in the photoelectric thermometer compartment, and connect the photoelectric thermometer to the interior of the photoelectric thermometer compartment;

[0034] Step 4: Input purge air into the photoelectric thermometer chamber. The purge air passes through the photoelectric thermometer, along the photoelectric thermometer chamber and into the peep tube, blowing out the coke particles that fall into the peep tube.

[0035] Compared with the prior art, the advantages of the present invention are:

[0036] (1) The present invention discloses an integrated coke cake thermometer. Unlike the existing split coke cake thermometers on the market, the present invention has no optical fiber components, is easy to install, use, and maintain, solves various problems existing in split thermometers, can effectively reduce installation and use costs, and has accurate measurement;

[0037] (2) The present invention connects the peep tube, the photoelectric thermometer and the photoelectric thermometer chamber into one body, and sets the photoelectric thermometer inside the photoelectric thermometer chamber to form a double-layer structure. After the purge air enters the photoelectric thermometer chamber, it first enters the chamber and contacts the photoelectric thermometer. Since the ambient temperature on site is high or low, the purge air of normal temperature can ensure that the photoelectric thermometer is always within a normal operating temperature range. The purge air rotates tangentially along the outer circle of the photoelectric thermometer from one side of the inner wall of the cast aluminum box and then enters the connecting pipe, thereby staying in the chamber for a longer time to fully realize heat exchange. The photoelectric thermometer and the positioning shaft are matched with a small gap, so that most of the purge air enters the annular gap between the outer tube and the inner tube along the radial hole, and the purge air is finally blown out from the peep tube to blow out the coke particles that fall into the peep tube;

[0038] (3) A sealing groove is machined on the outer wall of the positioning shaft of the present invention, into which an O-ring can be inserted. When the photoelectric thermometer is inserted into the positioning shaft, the interior of the photoelectric thermometer is connected to the inner hole of the inner tube. In this way, when the purge air enters the annular gap between the outer tube and the inner tube along the radial hole, the air blown out from the annular gap forms a micro vacuum in the inner area of ​​the inner tube, which can take out the dust and other impurities in the inner tube and prevent the moisture and impurities contained in the purge air from adhering to the lens of the photoelectric thermometer.

[0039] (4) A downward opening is left between the protective tube and the peep plate of the present invention, and the purge gas eventually flows into the atmosphere from here. This structure of the peep tube prevents rainwater from entering the peep tube when it rains. In addition, the optical path is isolated from the external high dust environment to the greatest extent. Even if the purge gas is temporarily cut off, the normal operation of the photoelectric thermometer can be guaranteed.

[0040] (5) The focusing plate in the peep tube of the present invention is provided with an inward tapered opening to prevent particles entering this position from getting stuck. The length of the protective tube is greater than or equal to the wall thickness of the focusing grid. During installation, the protective tube can be cut and welded to the peep tube flange to ensure a firm connection between the peep tube and the focusing grid. The peep tube of the present invention and the photoelectric thermometer chamber can be disassembled at the flange. After long-term use, the photoelectric thermometer chamber can be disassembled for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Example 1

[0058] like Figures 1 and 2 As shown, the present invention discloses an integrated coke cake thermometer, including a peep tube 1, a photoelectric thermometer 2 and a photoelectric thermometer chamber 3, one end of the peep tube 1 passes through the focus guide grid and is vertically installed on the inner side of the focus guide grid, and the end of the peep tube 1 is flush with the inner wall of the focus guide grid, and the other end of the peep tube 1 is welded to the outer wall of the focus guide grid, and one end of the peep tube 1 arranged on the outer wall of the focus guide grid is connected to the photoelectric thermometer chamber 3, wherein the photoelectric thermometer 2 is arranged inside the photoelectric thermometer chamber 3, and the photoelectric thermometer chamber 3 is provided with an air inlet pipe seat 3-9, and the air inlet pipe seat 3-9 is connected to the purge pipeline, and the purge air enters the photoelectric thermometer chamber 3 from the purge pipeline, passes through the photoelectric thermometer 2, and then enters the peep tube 1 from the photoelectric thermometer chamber 3 to blow out the coke particles that fall into the peep tube 1.

[0059] The photoelectric thermometer chamber 3 and the peep tube 1 are connected by a flange, which can be achieved by other methods.

[0060] Example 2

[0061] like Figure 2As shown, preferably, the peep tube 1 is composed of a peep tube plate 1-1, a protective tube 1-2 and a peep tube flange 1-3 connected in sequence, wherein the peep tube plate 1-1 passes through the focus guide grid and is vertically installed on the inner side of the focus guide grid, and the end face of the peep tube plate 1-1 is flush with the inner wall of the focus guide grid, the peep tube flange 1-3 is welded to the outer wall of the focus guide grid, and the length of the protective tube 1-2 is greater than or equal to the wall thickness of the focus guide grid.

[0062] The peep tube flange 1-3 is a separate accessory and is welded on site. The welding position is the outer wall of the focus guide grid. The length of the protective tube 1-2 is long enough. The protective tube 1-2 is cut on site according to the wall thickness of the focus guide grid, and then the peep tube 1 is welded to the focus guide grid as a whole.

[0063] like Figure 2 As shown, preferably, the focusing plate 1-1 is provided with a tapered hole 1-1-1 along the axial direction, and the diameter of the tapered hole 1-1-1 gradually increases as it approaches the protective tube 1-2.

[0064] The focusing peek plate 1-1 has a conical hole 1-1-1, which is made of wear-resistant material. It is installed on the inner side of the focus guide grid and is flush with the inner wall of the focus guide grid. During operation, the coke slides along the inner wall of the focus guide grid. Therefore, the energy emitted by this conical hole 1-1-1 when the coke passes through is related to the coke temperature.

[0065] like Figure 2 As shown, preferably, an opening 1-2-1 is provided at the junction of the protective tube 1-2 and the focusing plate 1-1, wherein the opening 1-2-1 is opened vertically downward.

[0066] The protective tubes 1-2 can be cancelled or replaced by tubes of other shapes.

[0067] The direction of coke movement is perpendicular to the center of the peep tube 1, but it is inevitable that some small particles will overflow from the tapered hole 1-1-1 toward the protective tube 1-2 under the action of the extrusion pressure. The tapered hole 1-1-1 has a larger aperture facing the protective tube 1-2, so that the overflowing coke particles will not be stuck, but fall downward under the action of gravity. An opening 1-2-1 is left in the downward direction at the junction of the protective tube 1-2 and the peep plate 1-1, so that the overflowing coke particles will fall from this opening to the outside of the peep tube 1, thereby ensuring the smooth flow of the measurement path.

[0068] The size of the opening 1-2-1 can be designed to be different according to conditions.

[0069] The purge air enters from the mouth of the protective tube 1-2 at one end of the peep tube flange 1-3, blows forward along the protective tube 1-2 and blows downward from the opening 1-2-1, and brings the smoke and dust overflowing from the tapered hole 1-1-1 out of the temperature measurement space through the opening 1-2-1.

One end of the outer tube 3-3 is coaxially sleeved in the positioning shaft 3-8 close to the chamber flange 3-1 with a small gap. The inner diameter of the outer tube 3-3 is larger than the outer diameter of the inner tube 3-2. The distance between the end of the outer tube 3-3 away from the connecting tube 3-5 and the chamber flange 3-1 is greater than the distance between the end of the inner tube 3-2 away from the connecting tube 3-5 and the chamber flange 3-1. The side of the inner tube 3-2 away from the positioning shaft 3-8 is coaxially sleeved in the outer tube 3-3, and the side of the outer tube 3-3 away from the positioning shaft 3-8 is coaxially sleeved in the protective tube 1-2.

[0072] During operation, the purge air enters the cast aluminum box 3-7 from the air inlet pipe seat 3-9 and moves to the left along the gap between the connecting pipe 3-5 and the photoelectric thermometer 2. The positioning shaft 3-8 is provided with radial holes 3-8-1 along the circumferential direction. The purge air enters the annular gap between the inner tube 3-2 and the outer tube 3-3 along the circumferential radial holes 3-8-1 and is finally blown out to the left.

[0073] Example 4

[0075] The cast aluminum box 3-7 is divided into two parts. The cast aluminum box body 3-7-1 and the cast aluminum box cover 3-7-2 are equipped with hinges on one side. When maintaining, the four screws on the cast aluminum box cover 3-7-2 are disengaged from the cast aluminum box body 3-7-1, and the cast aluminum box cover 3-7-2 can be rotated to one side. The four screws are fixed screws and are always connected to the cast aluminum box cover 3-7-2. In this way, no parts will be lost or dropped during high-altitude operation.

[0076] When the photoelectric thermometer 2 needs to be repaired, the cast aluminum box cover 3-7-2 of the cast aluminum box 3-7 can be opened, and the photoelectric thermometer 2 can be directly pulled out for easy maintenance.

[0077] An elastic part can be provided between the photoelectric thermometer 2 and the cast aluminum box cover 3-7-2 of the cast aluminum box 3-7, so that when the photoelectric thermometer 2 is inserted into the positioning shaft 3-8, the cast aluminum box cover 3-7-2 is closed and the screws are tightened, the photoelectric thermometer 2 will be firmly positioned and will not be affected by external vibrations.

[0078] The air intake pipe seat 3-9 on the cast aluminum box 3-7 is located at the lower left position of the cast aluminum box 3-7, and air can be taken in from other parts as needed.

[0079] The cast aluminum boxes 3-7 are square, and can also be of other shapes, and can be made of other materials.

[0080] There is one or two air inlet pipe seats 3-9 to form two paths of purge air, one path for cooling the photoelectric thermometer and the other path for purge air.

[0081] like Figure 4 As shown, preferably, the positioning shaft 3-8 is a variable diameter hollow shaft, the inner diameter and outer diameter on one side of the positioning shaft 3-8 are small, the inner tube 3-2 is coaxially mounted in the small inner diameter of the positioning shaft 3-8 with a small gap, the inner diameter and outer diameter on the other side of the positioning shaft 3-8 are large, one end of the outer tube 3-3 is coaxially mounted in the large inner diameter of the positioning shaft 3-8 with a small gap, the outer wall of the large outer diameter of the positioning shaft 3-8 is mounted in the chamber flange 3-1 with a small gap, a radial hole 3-8-1 is radially opened at the place where the inner and outer diameters of the positioning shaft 3-8 change, and a sealing groove 3-8-2 is opened on the outer wall of the small outer diameter of the positioning shaft 3-8, and an O-ring is provided in the sealing groove 3-8-2 for sealing connection with the photoelectric thermometer 2.

[0084] like Figure 2As shown, preferably, the photoelectric thermometer 2 is arranged in a cast aluminum box 3-7, and the photoelectric thermometer 2 includes a lens barrel 2-1, an electronic box 2-2 and an aviation plug 2-3, wherein the lens barrel 2-1 is connected to the left side of the electronic box 2-2, and the aviation plug 2-3 is connected to the lower side of the electronic box 2-2, and the lens barrel 2-1 is coaxially sleeved in the connecting tube 3-5, the outer diameter of the lens barrel 2-1 is smaller than the inner diameter of the connecting tube 3-5, and the end of the lens barrel 2-1 is matched with the positioning shaft 3-8 with a small gap, and the end of the lens barrel 2-1 and the positioning shaft 3-8 are sealed by an O-ring, and the lower end of the aviation plug 2-3 is plugged into the cable connector 3-10.

[0085] Because of the presence of the O-ring seal, the purge wind will not enter the inner tube 3-2, preventing the wind from blowing towards the lens.

[0086] The photoelectric thermometer 2 itself has an aviation plug 2-3, and the cable extends from a cable connector 3-10 installed on the cast aluminum box 3-7. The cable connector 3-10 can firmly clamp the cable to achieve waterproof and dustproof effects.

[0089] The photoelectric thermometer lens and the temperature measuring point are directly connected, so air can flow. A glass window can also be installed between the temperature measuring point and the lens to completely isolate the thermometer from the external space.

[0090] Preferably, the photoelectric thermometer 2 is connected to the positioning shaft 3-8 of the photoelectric thermometer chamber 3 by plugging. When the box cover is tightened with the box through 4 screws, the elastic pad bonded to the inside of the box cover presses the photoelectric thermometer to prevent shaking.

[0091] Preferably, the photoelectric thermometer is arranged on one side of the compartment box 3-7 so that the aviation plug can be easily plugged in and out.

[0092] Preferably, the cable at the rear of the aviation plug is clamped on the compartment 3 through a cable connector, which is dustproof and waterproof.

[0093] Example 6

[0094] Preferably, a method for using the integrated coke cake thermometer as described in any one of the above items comprises the following steps:

[0095] Step 1: Install one end of the peep tube 1 on the inner side of the focus guide grid, and make the end of the peep tube 1 flush with the inner wall of the focus guide grid, and weld the other end of the peep tube 1 to the outer wall of the focus guide grid;

[0096] Step 2: Connect the peep tube 1 on the outer wall of the focus guide grid to one side of the photoelectric thermometer chamber 3;

[0097] Step 3: Install the photoelectric thermometer 2 in the photoelectric thermometer chamber 3, and connect the photoelectric thermometer 2 to the inside of the photoelectric thermometer chamber 3;

[0098] Step 4: Input purge air into the photoelectric thermometer chamber 3. The purge air passes through the photoelectric thermometer 2 and enters the peep tube 1 along the photoelectric thermometer chamber 3 to blow out the coke particles that fall into the peep tube 1.

[0099] The working principle of the present invention is as follows:

[0100] According to the integrated design concept, the present invention installs the peep tube 1 on one side of the focus plate 1-1 through the focus guide grid vertically on the inner side of the focus guide grid, and the end face of the peep tube 1-1 is flush with the inner wall of the focus guide grid, and the peep tube flange 1-3 is welded to the outer wall of the focus guide grid. During operation, the coke slides through the inner wall of the focus guide grid, so the energy emitted by this tapered hole 1-1-1 when the coke passes through is related to the coke temperature. The other end of the peep tube flange 1-3 is connected to the chamber flange 3-1, so that the outer tube 3-3 is coaxially sleeved in the protective tube 1-2, and the inner tube 3-2 is coaxially sleeved in the outer tube 3-3. The other end of the inner tube 3-2 is connected to the photoelectric thermometer 2, and the energy emitted by the coke cake is directly converted into the coke cake temperature through the photoelectric thermometer 2. The photoelectric thermometer 2 is connected to the outside through a cable, and the purge air is input through the air inlet pipe seat 3-9, and the purge air enters the photoelectric thermometer. After entering the chamber 2, it first enters the chamber and contacts the photoelectric thermometer 2 to ensure that the photoelectric thermometer 2 is always within a normal operating temperature range. The purge air rotates tangentially along the outer circle of the photoelectric thermometer 2 from one side of the inner wall of the cast aluminum box 3-7 and then enters the connecting pipe 3-5, thereby staying in the chamber for a longer time to fully realize heat exchange. The photoelectric thermometer 2 and the positioning shaft 3-8 are matched with a small gap, so that most of the purge air enters the annular gap between the outer tube 3-3 and the inner tube 3-2 along the radial hole 3-8-1, which will form a slight negative pressure in the inner tube 3-2 to prevent the moisture and impurities contained in the purge air from adhering to the photoelectric thermometer lens. Then the purge air enters the protective tube 1-2 along the inner wall of the outer tube 3-3, and brings the smoke and dust overflowing from the tapered hole 1-1-1 to the outside of the temperature measuring space from the opening 1-2-1.

[0101] The present invention discloses an integrated coke cake thermometer. Unlike the existing split coke cake thermometers on the market, the present invention has no optical fiber components, is easy to install and use, and is convenient to maintain. It solves various problems existing in split thermometers, can effectively reduce installation and use costs, and has accurate measurement.

[0102] The present invention connects a peep tube, a photoelectric thermometer and a photoelectric thermometer chamber into one body, and arranges the photoelectric thermometer inside the photoelectric thermometer chamber to form a double-layer structure. After the purge air enters the photoelectric thermometer chamber, it first enters the chamber and contacts the photoelectric thermometer. Since the ambient temperature on site is high or low, the purge air of normal temperature can ensure that the photoelectric thermometer is always within a normal operating temperature range. The purge air rotates tangentially along the outer circle of the photoelectric thermometer from one side of the inner wall of the cast aluminum box and then enters the connecting pipe, thereby staying in the chamber for a longer time to fully realize heat exchange. The photoelectric thermometer and the positioning shaft are matched with a small gap, so that most of the purge air enters the annular gap between the outer tube and the inner tube along the radial hole, and the purge air is finally blown out from the peep tube to blow out the coke particles that fall into the peep tube.

[0103] The outer wall of the positioning shaft of the present invention is processed with a sealing groove, which can be installed with an O-ring. When the photoelectric thermometer is inserted into the positioning shaft, the interior of the photoelectric thermometer is connected to the inner hole of the inner tube. In this way, when the purge air enters the annular gap between the outer tube and the inner tube along the radial hole, the air blown out from the annular gap forms a micro vacuum in the internal area of ​​the inner tube, which can bring out dust and the like inside the inner tube, and at the same time prevent moisture and impurities contained in the purge air from adhering to the photoelectric thermometer lens.

[0104] A downward opening is left between the protective tube and the peep tube plate of the present invention, and the purge gas eventually flows into the atmosphere from here. This structure of the peep tube prevents rainwater from entering the inside of the peep tube when it rains. In addition, the optical path is isolated from the external high-dust environment to the greatest extent. Even if the purge gas is cut off for a short time, the normal operation of the photoelectric thermometer can be guaranteed.

[0105] The focusing plate in the peep tube of the present invention is provided with an inward tapered opening to prevent particles entering this position from getting stuck. The length of the protective tube is greater than or equal to the wall thickness of the focusing guide grid. During installation, the protective tube can be cut and welded to the peep tube flange as a whole, thereby ensuring that the peep tube and the focusing guide grid are firmly connected. The peep tube and the photoelectric thermometer chamber of the present invention can be disassembled at the flange. After long-term use, the photoelectric thermometer chamber can be disassembled for cleaning. The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present invention.

[0106] Many other changes and modifications can be made without departing from the spirit and scope of the present invention. It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
