Description

A flame detector structure with flame shooting function

Technical Field

The invention relates to the technical field of flame detection, in particular to a flame detector structure with a flame shooting function.

Background Art

Flame detectors are used in power generation equipment such as coal-fired boilers and heavy-duty gas turbines to detect whether there is a flame in the combustion chamber. When the combustion chamber fails to ignite or is extinguished, an alarm message needs to be issued and the fuel supply needs to be cut off immediately to prevent the fuel concentration in the combustion chamber from being too high, avoiding explosions and damage to other equipment when ignited next time.

At present, ultraviolet flame detectors are used in heavy-duty gas engines. The principle is that when the fuel is just ignited, it will radiate strong energy ultraviolet light at an extremely fast speed (3-4ms). The ultraviolet flame detector senses the ultraviolet light generated by the flame through the ultraviolet light sensor and converts it into an electrical signal for analysis and processing to determine whether there is a flame. Therefore, the ultraviolet flame detector has the advantages of high sensitivity and fast flame response speed. In addition, common flame detectors include infrared flame detectors and ultraviolet/infrared composite flame detectors.

For gas turbines, since the flame temperature in the combustion chamber is as high as about 2000℃ and the ambient pressure is as high as 2MPa, the flame detection environment is much worse than that of coal-fired boilers. At present, it is still impossible to obtain flame image information in the combustion chamber during normal operation of the gas turbine. Moreover, flame detection uses a single ultraviolet light, which leads to the redundant setting of the flame detector mainly relying on the number of flame detectors installed. In addition, the existing flame detector can only determine whether there is a flame in the combustion chamber, and cannot obtain information such as combustion organization and flame image information.

When in use, the conduit 102 is used to penetrate the flame tube and the cylinder of the gas turbine, so that the flame spectrum signal generated during combustion in the cylinder can be introduced into the conduit 102. The inner diameter of the conduit 102 is preferably 10-50 mm, which can meet the requirements of detection components of different sizes. A quartz glass 103a is installed inside the conduit 102. With reference to FIG. 3, a first sealing ring 103b is fixed between the lower end of the quartz glass 103a and the installation step in the conduit 102.

In addition, a cooling gas ring cavity 103d is provided on the outer side of the conduit 102, and a plurality of air inlet holes 103e are circumferentially spaced apart on the conduit 102 at the lower end of the quartz glass 103a. The air inlet holes 103e and the central axis of the conduit 102 form an angle of 30°-45°. The treated compressed air free of oil and water enters the cooling gas ring cavity 103d along the air inlet pipe 103f, and enters the conduit downward through the air inlet holes 103e. The cooling gas is used to cool the conduit 102 and the quartz glass 103a on the one hand, and is used to isolate the fuel gas from contacting the quartz glass 103a on the other hand, so as to prevent the quartz glass 103a from being contaminated and affecting the accuracy of the detection signal.

The invisible light detection unit 104 includes an infrared light sensor 104a and an ultraviolet light sensor 104d. An annular groove for accommodating the infrared light sensor 104a and the ultraviolet light sensor 104d is provided inside the conduit 102, so that the infrared light sensor 104a and the ultraviolet light sensor 104d are vertically arranged with the visible light detection unit 105; wherein, the output end of the infrared light sensor 104a is connected to the infrared signal processing module 104b, and the infrared signal processing module 104b is connected to the server through the infrared signal line 104c, and the output end of the ultraviolet light sensor 104d is connected to the ultraviolet signal processing module 104e, and the ultraviolet signal processing module 104e is connected to the server through the ultraviolet signal line 104f.

Taking Figure 2 as a reference, the reflective filter lens 105a is fixed inside the conduit 102, and the conduit 102 reflects and filters the ultraviolet light and infrared light generated by the flame, which improves the shooting quality of the flame image on the one hand, and provides the infrared light and ultraviolet light generated by the flame to the infrared light sensor 104a/ultraviolet light sensor 104d on the other hand, to prevent the conduit 102 from having too large an aspect ratio and affecting the signal acquisition of the infrared light sensor 104a/ultraviolet light sensor 104d; the image collector 105b is installed behind the reflective filter lens 105a, and collects the visible light generated by the flame, thereby obtaining flame image information; the image processing module 105c collects the information of the image collector 105b, and stores, detects and outputs the collected visible light signal through the image transmission line 105d, and obtains the flame image information in the combustion chamber in real time.

The main function of the reflective filter lens 105a is to filter and focus light. The reflective filter lens 105a can reflect light of a specific wavelength (infrared light and ultraviolet light in this case).

The reflective filter lens 105a improves the quality of the flame image because it filters out non-visible light that may interfere with image analysis. At the same time, it provides accurate light signals for the infrared light sensor and the ultraviolet light sensor, which helps the sensor detect flames more effectively.

2 and 3 are used as references, the infrared light sensor 104a and the ultraviolet light sensor 104d are installed relative to each other, wherein the infrared light sensor 104a and the ultraviolet light sensor 104d are used to detect the ultraviolet light and infrared light generated by the flame; the infrared signal processing module 104b and the ultraviolet signal processing module 104e are connected to the corresponding sensors for denoising, amplifying and transmitting the ultraviolet light signal and the infrared light signal.

Example 2

Referring to Figs. 3-5, the second embodiment of the present invention is different from the previous embodiment in that it further includes a flow guide assembly 200, which is arranged on the isolation protection assembly 103, and includes a first flow guide ring 201 installed on the conduit 102, the first flow guide ring 201 is used to connect the external cooling gas, and a second flow guide ring 202 driven by the first flow guide ring 201 is provided on one side of the first flow guide ring 201, and the second flow guide ring 202 is used to guide the gas to flow uniformly. The first flow guide ring 201 includes a fixed ring 201a fixed inside the cooling gas ring cavity 103d, and an annular cover plate 201b is sleeved on the outer side of the fixed ring 201a, and the annular cover plate 201b is connected to the air inlet pipe 103f, and the connecting end of the air inlet pipe 103f is at an angle of 20°-60° with the central axis of the annular cover plate 201b. A power ring 201c is provided between the fixed ring 201a and the annular cover plate 201b, the power ring 201c is rotatably connected to the fixed ring 201a, and a plurality of guide blades 201d are fixed to the outside of the power ring 201c. The second flow guide ring body 202 includes a driven ring 202a fixedly connected to the power ring 201c, the driven ring 202a is rotatably connected to the conduit 102, an air cavity 202c is provided on one side of the driven ring 202a facing the power ring 201c, and a plurality of guide holes 202b communicating with the air cavity 202c are provided at intervals on one side of the driven ring 202a away from the air cavity 202c.

As can be seen from Example 1, since there is no mechanism for uniformly guiding the cooling gas inside, the multiple air inlet holes 103e cannot uniformly intake air, causing the conduit 102 to be unevenly cooled, which may affect the structural integrity, long-term durability and signal accuracy.

With reference to FIG. 5 , when the air inlet pipe 103f delivers the cooling gas to the inside of the annular cover plate 201b, since the air delivery end of the air inlet pipe 103f is inclined, and the inclination angle is preferably 45°, the ejected cooling gas has a strong thrust on the guide blade 201d, and the power ring 201c drives the fixedly connected driven ring 202a to rotate continuously, and the power ring 201c drives the fixedly connected driven ring 202a to rotate;

At the same time, the cooling gas will enter the air cavity 202c and be ejected from multiple guide holes 202b connected to the air cavity 202c. When the cooling gas is ejected, it is affected by the rotation of the driven ring 202a, so that the cooling gas ejected from the guide hole 202b has no dead angle and can flow evenly in the conduit 102, so that the cooling is more uniform and the durability of the components is improved.

The cooling gas is sprayed into the conduit 102 evenly through the multiple air inlet holes 103e without dead angles, which can avoid damage caused by local overheating or insufficient cooling. The uniform cooling helps to maintain the integrity and stability of the structure and extend its service life.

The rotating design of the power ring 201c and the driven ring 202a increases the dynamic characteristics of the mechanism, helps the cooling gas to form a stable flow state in the cooling gas ring cavity 103d, thereby avoiding the cooling blind spot of the duct 102. The uniform and effective cooling reduces fatigue damage caused by thermal stress, thereby improving the durability and reliability of the components.

Among them, the annular cover plate 201b is fixedly connected to the fixed ring 201a, so the annular cover plate 201b will not rotate with the power ring 201c, making the air intake pipe 103f and the annular cover plate 201b more stable when fixed; the guide blade 201d is inclined toward the air cavity 202c, and the inclination angle is preferably 30°, which guides the compressed cooling gas and enables the cooling gas to quickly enter the air cavity 202c; the driven ring 202a is rotatably sleeved on the conduit 102 to improve the uniformity of cooling.

Example 3

Referring to Fig. 6-8, the third embodiment of the present invention further provides a flame detector structure with flame shooting function. It includes a driven ring 202a, and a centrifugal force assembly 300 is arranged inside the driven ring 202a for detecting the rotation speed of the driven ring 202a, which includes a plurality of centrifugal grooves 301 opened inside the driven ring 202a, a centrifugal piston block 302 is slidably connected inside the centrifugal groove 301, and a tension spring 303 is fixedly connected between the centrifugal piston block 302 and the centrifugal groove 301, and a plurality of storage grooves 305 corresponding to the centrifugal grooves 301 are arranged on the periphery of the driven ring 202a, and the storage grooves 305 are connected to the centrifugal grooves 301 through a connecting hole 304, and the storage grooves 305 are filled with a magnetic solution. The centrifugal force assembly 300 also includes a detection ring 306 fixed on the outside of the conduit 102, and a magnetic ring 307 is rotatably connected inside the detection ring 306, and paddles 308 are fixed on the periphery of the magnetic ring 307, and a plurality of collision blocks in contact with the paddles 308 are arranged inside the detection ring 306.

With reference to FIG. 7 , S1 and S2 are respectively a fault state and a normal operation state of the centrifugal force assembly 300 .

During long-term use, the inside of the air intake pipe 103f may be clogged by impurities or leak, resulting in a reduction in the air flow of the air intake pipe 103f, thereby affecting the cooling effect.

When the air intake of the air intake pipe 103f is within a preset range, with S2 as a reference, the centrifugal force exerted by the rotation of the driven ring 202a on the centrifugal piston block 302 overcomes the elastic force of the tension spring 303, and the centrifugal piston block 302 slides and draws the magnetic solution in the storage tank 305 into the centrifugal tank 301 for storage through the connecting hole 304, thereby not driving the magnetic ring 307 to rotate by magnetic force, thereby avoiding false triggering.

When the air intake volume of the air intake pipe 103f decreases and is not within the preset range, with S1 as a reference, the centrifugal force exerted by the rotation of the driven ring 202a on the centrifugal piston block 302 is not enough to overcome the elastic force of the tension spring 303, and the centrifugal piston block 302 will slide and recover under the pull of the tension spring 303 and squeeze the magnetic solution. Under the action of pressure, the magnetic solution is transported to the storage tank 305 through the connecting hole 304. When the storage tank 305 is driven to rotate by the driven ring 202a, the magnetic ring 307 is driven to rotate by the magnetic force. When the magnetic ring 307 rotates, it drives the paddle 308 fixed on the outside to rotate. The paddle 308 will collide with the collision block at intervals to produce a prompt sound, so that the staff can inspect the components in time.

By adjusting the weight of the centrifugal piston block 302, the centrifugal piston block 302 can be controlled to be triggered when the centrifugal force is within a preset range.
