Technical Field

[0001] The utility model relates to the technical field of boiler burners, in particular to a high-efficiency thermal power generation boiler burner structure. Background Art

[0002] A burner is a general term for devices that spray fuel and air in a certain manner for mixed combustion. Burners are categorized by type and application into industrial burners, combustion machines, civil burners, and special burners. Burners, also called combustion machines, can be divided into oil burners and gas burners based on the fuel used; kiln burners and boiler burners based on the intended use; and industrial burners, civil burners, and special burners based on the application. Oil burners are categorized into light oil (such as diesel) and heavy oil burners (such as waste oil), while gas burners are categorized into natural gas burners, liquefied gas burners, city gas burners, and biogas burners. The burners we usually refer to are boiler burners.

[0003] The combustion effect of the existing boiler burner is poor, and it cannot burn efficiently for thermal power generation. The combustion is insufficient and does not have the function of automatically delivering and blocking gas delivery. Therefore, it is necessary to provide a high-efficiency thermal power generation boiler burner structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-efficiency thermal power generation boiler burner structure, which can effectively solve the problems of poor combustion effect of existing boiler burners in the background technology, inability to burn efficiently for thermal power generation, insufficient combustion, and lack of automatic delivery and blocking gas delivery functions.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a high-efficiency thermal power generation boiler burner structure, comprising a main body unit, and a pipe unit fixedly connected to the bottom of the main body unit, and further comprising an opening and closing unit arranged inside the pipe unit and a combustion unit arranged inside the main body unit;

[0006] The opening and closing unit includes a fixed cylinder arranged inside the pipeline unit, and a blocking valve movably arranged just below the bottom of the fixed cylinder for gas transmission and blocking;

[0007] The combustion unit comprises a combustion tube fixedly connected to the center of the main body unit, and a combustion ring tube arranged on the inner wall of the main body unit for sufficient combustion.

[0008] Preferably, the main unit includes a burner body, an air inlet pipe fixedly connected to one side of the burner body, and a plurality of air outlets distributed in a ring array on the inner wall surface of the top end of the burner body.

[0009] Preferably, the pipeline unit includes a connecting pipe fixedly connected to the bottom of the burner body, and a supporting block fixedly connected to the inner wall surface of the connecting pipe.

[0010] Preferably, the opening and closing unit also includes two fixed rods fixedly connected to the inner wall of the connecting tube, a movable rod movably arranged inside the bottom end of the fixed cylinder, a limit plate fixedly connected to the top of the movable rod, and a return spring fixedly connected to the top of the limit plate.

[0011] Preferably, the combustion unit further comprises a diverter pipe fixedly connected to the outer surface of the combustion tube, a combustion port opened on the top of the combustion ring tube, and an ignition valve arranged on one side of the combustion tube.

[0012] Preferably, the two sides of the fixed cylinder are fixedly connected to one end of the two movable rods respectively, the limit plate is movably arranged inside the fixed cylinder, the bottom end of the movable rod is fixedly connected to the top center of the blocking valve, and the reset spring is connected between the top of the limit plate and the inner top wall of the fixed cylinder.

[0013] Preferably, the interior of the combustion tube is connected to the interior of the connecting tube, there are four diverter tubes, the four diverter tubes are distributed in a ring array, and the top ends of the four diverter tubes are connected to the bottom of the combustion ring tube, and there are several combustion ports, which are distributed in a ring array on the top of the combustion ring tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the utility model, through the connection between the connecting pipe and the gas pipeline, when the gas is transported, the circulating air pressure of the gas is applied to the blocking valve, and the blocking valve is forced to move upward and separate from the supporting block, so that the supporting block pushes the movable rod to move toward the inside of the fixed cylinder, and the movement of the movable rod pushes the limit plate to move, and the movement of the limit plate compresses the return spring. At this time, the blocking valve is separated to allow the gas to enter the inside of the connecting pipe, thereby facilitating the gas to enter the combustion pipe for combustion. On the contrary, when the gas is closed, the return spring loses its extrusion force and elastically recovers to push the limit plate down, and the blocking valve is pushed down by the movable rod to form a blockage. This structure can have the functions of autonomously transporting gas and blocking gas, thereby improving the practicality of the burner body.

[0016] 2. In the present invention, the gas enters the interior of the combustion tube through the connecting pipe, the gas circulates inside the combustion tube, and then enters the interior of the four diversion tubes. The gas enters the interior of the combustion ring tube through the four diversion tubes, and then by opening the ignition valve, the gas is ignited through the combustion port to burn and generate electricity. The gas diversion through the four diversion tubes can increase the combustion range of the gas, and burn through the several combustion ports set at the top of the combustion ring tube. With the cooperation of the air inlet pipe and the air outlet, the burner body can burn more fully, and can burn efficiently to generate thermal power. BRIEF DESCRIPTION OF THE DRAWINGS
