Description

Technical Field

[0001] The utility model relates to the technical field of thermal power generation, in particular to a boiler cold air dynamic field fireworks tracing test device. Background Art

[0002] Coal-fired power plants require cold aerodynamic field tests during the construction period or after major repairs. This test involves fixing fireworks at specific burner nozzles, measuring the wind speeds of the primary and secondary air nozzles and adjusting them to the simulated wind speeds. The fireworks are then ignited and released, and the airflow motion state in the furnace is observed through the trajectory of the spark particles.

[0003] For example, the utility model patent with authorization announcement number CN206074220U discloses a tracer fireworks device for cold air dynamic field testing of boilers. The device includes a cylindrical jacket, tracer fireworks, a wireless remote control device, an ignition wire and a base for fixing the wireless remote control device. The inner wall of the cylindrical jacket is provided with a groove, and a sealing ring for cooperating with the tracer fireworks is provided in the groove. The tracer fireworks are inserted into the jacket to realize the arrangement of the tracer fireworks in the cylindrical jacket. The jacket, wireless remote control device and base are arranged as an integrated whole. The base is a magnet that is adsorbed inside the burner nozzle.

[0004] However, existing burner nozzles are mostly made of high-temperature resistant nickel-containing stainless steel alloys, which are generally non-magnetic metals with weak or no magnetic attraction. Therefore, magnetically securing fireworks within the burner nozzle is impossible. The release of fireworks generates a large amount of heat, which can cause the sealing ring in contact with the tracer fireworks to fail, making it impossible to stably position the tracer fireworks within the cylindrical jacket. Furthermore, the circuit board in the wireless control module and the fireworks themselves are both fixed in the cylindrical jacket. The high temperature generated by the fireworks after ignition may affect the normal operation of electronic components and even shorten the life of the remote control device. Furthermore, the wind speed at the nozzle needs to be measured before the test begins. Testing can only be carried out after the wind speed reaches a specific value. Existing techniques often require manual entry into the furnace to measure wind speed, which poses a safety risk when personnel are exposed to wind and dust. Utility Model Content

[0005] The purpose of the utility model is to provide a boiler cold air dynamic field fireworks tracer test device to solve the problem in the prior art that tracer fireworks and fireworks tracer test devices cannot be reliably fixed.

[0006] To achieve the above objectives, the boiler cold air dynamic field fireworks tracer test device in the present invention adopts the following technical solutions:

[0007] The present application provides a boiler cold aerodynamic field fireworks tracing test device, which includes fireworks, a wireless measurement and control module and a fireworks ignition device. The wireless measurement and control module is electrically connected to the fireworks ignition device, and the fireworks are ignited by controlling the fireworks ignition device. The fireworks are equipped with a fireworks fixing assembly, which includes a fireworks tube clamp and a magnet arranged outside the fireworks tube clamp. The magnet is used to be adsorbed on the water-cooled wall outside the burner.

[0008] Furthermore, a fixing frame for fixing the magnet is fixed outside the firework tube hoop, and the magnet is fixed in the fixing frame.

[0009] Furthermore, the fixing frame includes a fixing rod and a magnet mounting sleeve fixed on the fixing rod, and the magnet is mounted in the magnet mounting sleeve.

[0010] Furthermore, the fixing rod is provided with at least two magnet mounting sleeves, and each magnet mounting sleeve is equipped with a magnet.

[0011] Furthermore, at least two firework tube hoops are arranged along the firework axis.

[0012] Furthermore, the firework pipe hoop is a stainless steel pipe hoop, and the fixing frame is welded to the outside of the stainless steel pipe hoop.

[0013] Furthermore, the fireworks tube hoop is also movably equipped with a tightening bolt for further tightening the fireworks in the fireworks tube hoop. The tightening bolt is a clevis bolt, and each fireworks tube hoop is equipped with at least two clevis bolts in the circumferential direction.

[0014] Furthermore, the fireworks tracer test device also includes a wind speed measuring probe for testing the wind speed out of the burner nozzle. A wind speed probe clamp is provided at the lower end of the wind speed measuring probe, and the wind speed probe clamp is used to clamp and fix on the burner nozzle wall.

[0015] Furthermore, a magnet is provided at the bottom of the wireless measurement and control module. The bottom of the wireless measurement and control module is provided with a magnet for adsorbing on the water-cooled wall outside the burner. The wireless measurement and control module is also electrically connected to a wind speed measuring probe, and the wind speed detected by the wind speed measuring probe is used to control the ignition of fireworks by the fireworks ignition device.

[0016] The beneficial effects of the utility model are as follows: the utility model is an improved invention; the fireworks fixing assembly in the boiler cold air dynamic field fireworks tracing test device is adsorbed on the water-cooled wall outside the burner through the magnet provided at the outer end of the fireworks tube clamp, and the fireworks nozzle faces the burner nozzle. Since the water-cooled wall adopts an iron matrix, the fireworks fixing assembly can be firmly adsorbed on the water-cooled wall. Compared with the traditional arrangement of adsorbing the fireworks fixing assembly on the burner nozzle, the adsorption method is more solid; at the same time, the fireworks fixing assembly is designed to be a fireworks tube clamp structure, and the fireworks are stably adsorbed on the water-cooled wall through the fireworks tube clamp and the magnet outside the fireworks tube clamp, avoiding the prior art of fixing the fireworks in the fireworks fixing device by a sealing ring, and the structure is simple and easy to adjust.

[0020] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0021] The utility model is an improved boiler cold-state aerodynamic field fireworks tracing test device, in which fireworks are stably arranged in the fireworks fixing assembly by means of fastening bolts in the fireworks fixing assembly, and the fireworks are adsorbed on the water-cooled wall outside the burner by means of magnets provided at the outer end of the fireworks fixing assembly, so that the fireworks are stably arranged at the burner nozzle, while avoiding the problem in the prior art of setting fireworks in the fireworks fixing assembly by means of a sealing ring, which causes the sealing ring to fail due to the high temperature generated when the fireworks burn.

[0022] Specific embodiment 1 of a boiler cold air dynamic field fireworks tracer test device provided by the utility model:

[0023] like Figure 1 、 2As shown, the boiler cold air dynamic field fireworks tracer test device includes a firework 3, a firework fixing assembly, a wireless measurement and control module 2, a firework ignition device (not shown in the figure), a wind speed measurement probe 7, and a probe clamp 8. The firework 3 is fixed to the firework fixing assembly, which includes a firework tube hoop 4, a clevis bolt 41, a magnet 42, and a fixing frame for fixing the magnet. In this embodiment, two firework tube hoop 4 are provided and are spaced apart along the firework axis. The magnet 42 is fixed to the firework tube hoop 4 by a fixing frame. In this embodiment, the fixing frame includes a fixing rod 44 and two magnets fixed to the fixing rod 44. A mounting sleeve 43 is provided, and a magnet 42 is mounted within the magnet mounting sleeve 43. In this embodiment, the fireworks collar 4 has two threaded holes, each of which is threaded with a clevis bolt 41. The fireworks 3 are secured within the collar 4 via the two clevis bolts 41 movably mounted on the collar 4. The collar 4 and the fireworks 3 are attracted to the water-cooled wall 1 outside the burner via magnets 42 mounted on the outside of the collar 4, with the nozzle of the fireworks 3 facing the burner nozzle. Since the water-cooled wall 1 is generally made of iron, the fireworks 3 can be stably attracted to the water-cooled wall outside the burner via the fireworks fixing assembly. In this embodiment, the collar 4 is a stainless steel collar, and the fixing rod 44 is a stainless steel rod. The fixing rod is welded to the collar 4. In other embodiments, the collar 4 and the fixing rod may also be made of iron or other high-temperature resistant materials.

[0024] A magnet is also fixed to the outside of the wireless measurement and control module 2, and the wireless measurement and control module 2 is also adsorbed on the water-cooled wall 1 outside the burner through the externally fixed magnet. The wireless measurement and control module 2 is electrically connected to a fireworks ignition device (not marked in the figure) and a wind speed measuring probe 7. The wind speed measuring probe 7 is fixed on the burner nozzle wall. The wireless measurement and control module 2 receives the wind speed detected by the wind speed measuring probe 7 and adjusts the wind speed ejected from the burner nozzle through the control system of the burner nozzle. When the wind speed detected by the wind speed measuring probe 7 reaches the modeled wind speed, the wireless measurement and control module 2 controls the fireworks ignition device to ignite the fireworks 3 according to the feedback value of the wind speed measuring probe 7. The fireworks ignition device is an existing conventional fireworks igniter and will not be described in detail here.

[0025] The burner nozzle includes a primary air burner nozzle 5 and a secondary air burner nozzle 6. In this embodiment, the nozzle of the fireworks 3 is facing the primary air burner nozzle 5, and wind speed probes 7 are fixed in the primary air burner nozzle 5 and the secondary air burner nozzle 6. In this embodiment, the wind speed probes 7 are fixed on the pipe walls of the primary air burner nozzle 5 and the secondary air burner nozzle 6 through a probe clamp 8.

[0026] Example 2 differs from Example 1 in that, whereas in Example 1, the fireworks were secured within the fireworks' collar using two clevis bolts provided on the collar, this embodiment does not require the clevis bolts. Instead, the collar itself can be tightened to secure the fireworks, using a collar that matches the size of the fireworks. In other embodiments, only one or more clevis bolts may be provided, and in other embodiments, other adjustment bolts or other fasteners may be used to secure the fireworks.

[0027] Example 3 is different from Example 1 in that, in Example 1, the magnet provided on the outside of the fireworks tube hoop is fixed to the outside of the fireworks tube hoop by a fixing frame. In this embodiment, no additional fixing frame is required. The fireworks tube hoop is made of an iron tube hoop, and the magnet is directly magnetically attracted to the outside of the fireworks tube hoop, or the fireworks tube hoop has a threaded hole, a threaded blind hole is opened on the magnet, and the magnet is fixed to the fireworks tube hoop by screws.

[0028] In embodiment 1, at least two firework tube hoops are arranged along the firework axis. In other embodiments, one or more firework tube hoops are also provided.

[0029] In Example 1, the wind speed measuring probe is clamped and fixed on the burner nozzle wall by a probe clamp. In other embodiments, the bottom of the wind speed measuring probe can also be fixed to the inner wall of the burner nozzle by gluing.

The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
