Description

Technical Field

[0001] This utility model relates to the field of combustion chamber structure technology, and more specifically, to an explosion-proof combustion chamber structure. Background Technology

[0002] The burner head is the key core component of the entire burner. Its function is to mix the fuel gas and combustion air and organize combustion to release heat for practical needs. The structure of this component determines the reliability and stability of the combustion process, as well as the velocity and temperature distribution throughout the combustion zone, all of which are key factors affecting flue gas emissions.

[0003] Among them, the patent with announcement number CN218442286U discloses an adjustable premixed burner premixed chamber structure, including an intake cone, a mixing disc, a gas butterfly valve adapter, a mixing disc adjusting screw, a mixing chamber, an annular hole in the intake cone, and a flame tube. The inner cavity of the intake cone is coaxially provided with an adjusting rod flow stabilizer. The inner cavity of the adjusting rod flow stabilizer has a threaded hole and the mixing disc adjusting screw is threadedly connected to the inner cavity of the threaded hole. The inner end of the mixing disc adjusting screw is connected to the mixing disc. One end of the gas butterfly valve adapter is welded to the mixing chamber and the other end is connected to the natural gas butterfly valve interface flange.

[0004] When in use, this structure can control the mixing ratio to make the combustion temperature lower than the theoretical combustion temperature, and also lower or slightly higher than the starting temperature of thermal nitrogen oxides formation. This can reduce the amount of nitrogen oxides generated. Compared with traditional diffusion combustion, the combustion conditions are better, the oxygen-air coefficient is better controlled, and the waste of gas heat energy is reduced while reducing the generation of nitrogen oxides and carbon dioxide. However, it is not easy to control the intake air volume within a certain range to achieve temperature control, and the direct emission of flue gas also pollutes the environment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an explosion-proof combustion chamber structure, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: an explosion-proof combustion chamber structure, including a combustion chamber cylinder for guiding airflow, wherein an air intake control assembly is provided on the combustion chamber cylinder;

[0007] The air intake control assembly includes two flow divider fans disposed inside the combustion chamber for flow splitting, and a valve for controlling the flow rate is disposed between the two flow divider fans. Both the flow divider fans and the valve are provided with a horizontal shaft for support.

[0008] An ignition controller for power supply is provided at one end of the inner cavity of the combustion chamber, and a temperature sensor for temperature detection is provided at one end of the horizontal shaft. The air intake control assembly also includes a support frame disposed inside the combustion chamber. The support frame is detachably connected to the combustion chamber, and a number of guide fans are disposed on the outer side of the support frame, each located on one side of a corresponding split fan cylinder.

[0009] As can be seen, in the above technical solution, the temperature sensor feedback controls the flow guide fan to be fully open, allowing airflow to enter the combustion chamber. The valve is closed to block the middle of the combustion chamber, while the valve is open to connect the two ends of the combustion chamber, enabling segmented control of the combustion chamber. Furthermore, the temperature sensor senses the temperature inside the combustion chamber and then works with the flow guide fan to deliver airflow into the combustion chamber, thereby regulating the oxygen content inside the combustion chamber and preventing deflagration.

[0010] Optionally, in a possible implementation, a protective tube is fitted around the outside of the combustion chamber. Two protective sleeves are provided on the protective tube, and each of the two protective sleeves is provided with an external leakage filter screen. Each external leakage filter screen is located on the side of a corresponding guide fan. Hollow discs are provided at both ends of the protective tube, and each hollow disc is installed on the protective tube through a butt joint. The two hollow discs are connected through a flue gas pipeline, and a filter is embedded in one of the hollow discs.

[0011] As can be seen, in the above technical solution, the exhaust pipe connects the two ends of the combustion chamber, making it easier for the flue gas to be filtered by the filter and discharged into the atmosphere, thus reducing pollution.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up the intake control assembly, the ignition controller delivers the combustion medium to the combustion chamber for combustion. The temperature sensor feedback controls the flow guide fan to open fully, allowing airflow to enter the combustion chamber. The valve closes, sealing the middle of the combustion chamber. The exhaust pipe connects the two ends of the combustion chamber, facilitating the filtration of flue gas before it is discharged into the atmosphere, reducing pollution.

[0014] The valve opening connects the two ends of the combustion chamber, enabling segmented control of the combustion chamber. The temperature sensor detects the temperature inside the combustion chamber and, in conjunction with the airflow guide fan, delivers airflow into the combustion chamber, thereby regulating the oxygen content and preventing deflagration.

[0022] As attached Figures 1-4 The anti-deflagration combustion chamber structure shown uses a control air intake component on the upper combustion chamber cylinder 1. When valve 4 is opened, the two ends of the inner cavity of the combustion chamber cylinder 1 are connected, realizing the function of segmented control of the combustion chamber of the combustion chamber cylinder 1. The temperature sensor 6 senses the temperature inside the combustion chamber cylinder 1 and then works with the guide fan 8 to deliver airflow into the combustion chamber cylinder 1, thereby regulating the oxygen content inside the combustion chamber cylinder 1 and preventing deflagration. The specific structural settings of the components are as follows.

[0023] The intake control assembly includes two flow divider fans 2 disposed inside the combustion chamber 1 for flow splitting, and a valve 4 for flow control is disposed between the two flow divider fans 2. Both the flow divider fans 2 and the valve 4 are provided with a horizontal shaft 3 for support.

[0024] An ignition controller 5 for power supply is provided at one end of the inner cavity of the combustion chamber 1, and a temperature sensor 6 for temperature detection is provided at one end of the horizontal shaft 3.

[0025] The intake control assembly also includes a support frame 7 disposed inside the combustion chamber 1. The support frame 7 is detachably connected to the combustion chamber 1, and a number of guide fans 8 are disposed on the outside of the support frame 7, which are respectively located on one side of the corresponding split fan cylinder 2.

[0026] The outer side of the combustion chamber 1 is fitted with a protective tube 15, and two protective sleeves 9 are provided on the protective tube 15. Each of the two protective sleeves 9 is provided with an external leakage filter 10, and each external leakage filter 10 is located on one side of the corresponding guide fan 8. Hollow discs 14 are provided at both ends of the protective tube 15, and each hollow disc 14 is installed on the protective tube 15 through a connector 13. The two hollow discs 14 are connected through the exhaust pipe 12, and a filter 11 is embedded in one of the hollow discs 14.

[0027] The specific working principle is as follows: the ignition controller 5 delivers the combustion medium to the combustion chamber 1 for combustion. The temperature sensor 6 controls the flow guide fan 8 to be fully open, allowing airflow to enter the combustion chamber 1. The valve 4 is closed to block the middle of the combustion chamber 1. The valve 4 is opened to connect the two ends of the inner cavity of the combustion chamber 1, realizing the function of segmented control of the combustion chamber of the combustion chamber 1. The temperature sensor 6 senses the temperature inside the combustion chamber 1 and then works with the flow guide fan 8 to deliver airflow to the combustion chamber 1, thereby regulating the oxygen content inside the combustion chamber 1 and preventing deflagration.

[0028] Furthermore, by using temperature sensor 6 to provide feedback on the opening of valve 4 and the airflow delivered by guide fan 8, the intake volume is controlled within a certain range, thereby achieving temperature control.

[0029] Furthermore, the exhaust pipe 12 connects the two ends of the combustion chamber 1, making it easier for the flue gas to be filtered by the filter 11 and discharged into the atmosphere, thus reducing pollution.
