[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, and preferred embodiments described herein are intended to illustrate and explain the present invention, and is not intended to limit the invention.
[0037] See all drawings, a industrial gas low nitrogen energy saver, including:
[0038] Box 1, the internal part is a combustion chamber 11, a mixed chamber 12, a cleaning chamber 13;
[0039] Gas pipeline module 2, placed outside of the box 1, the gas pipeline module 2 in communication with the mixing chamber 12;
[0040] The circulation device 3 is disposed in the combustion chamber 11, the circulating device 3 communicates the combustion chamber 11 and the cleaning chamber 13.
[0041] As an embodiment of the present invention, the casing 1 is fixedly disposed having a windshield 14 and an exhaust gas filter plate 15 for isolating the combustion chamber 11, a mixing chamber 12, and the exhaust gas. The filter plate 15 is used to isolate the mixing chamber 12, the cleaning chamber 13.
[0042] As an embodiment of the present invention, the circulating device 3 includes:
[0043] The circulating fan 31 is fixed in the combustion chamber 11;
[0044] The circulation line 32, the outer wall of the casing 1 is also provided with a circulation line 32, and the circulating line 32 is in communication with the circulating fan 31 and the other end communicates with the cleaning chamber 13.
[0045] As an embodiment of the present invention, the gas pipeline module 2 includes:
[0046] The combustion nozzle 21 is fixed to the windshield 14, and the combustion nozzle 21 is facing the combustion chamber 11;
[0047] Gas pipeline 22, one end is in communication with the external gas source, and the other end is in communication with the combustion nozzle 21;
[0048] Air pipeline 24, one end communicate with external air, and the other end communicates with the combustion nozzle 21;
[0049] The ignition branch 23, one end is in communication with the external gas source, and the other end is in communication with the combustion nozzle 21.
[0050] As an embodiment of the present invention, the gas pipeline 22 is sequentially connected in series along the gas flow direction, and the inlet pressure table 42, a flow meter 43, a first pressure reducing valve 44, a main solenoid valve 45, a secondary solenoid valve. 46, the proportional valve 47, the first button ball valve 48.
[0051] As an embodiment of the present invention, the ignition branch 23 is connected to the gas line 22, and the connection point is located between the flow meter 43 and the pressure relief valve, and the other end of the ignition branch 23 and the combustion. The nozzle 21 is connected to the ignition branch 23, and the second pressure reducing valve 51, the ignition solenoid valve 52, the second button ball valve 53, an inlet ball valve 54, the ignition metal hose 55 are sequentially connected in series.
[0052] As an embodiment of the present invention, there is a proportional motor 61, an air flow regulating valve 62, and a wind pressure switch 63 in series.
[0053] The operation principle of the above technical solution: An industrial gas low nitrogen energy-saver provided by the present invention, placing the combustion module of the gas in the combustion chamber, and placed the combustion nozzle in the combustion chamber, and combing the combustion module by metal pipeline And the combustion nozzle is connected. External gas and external air enters the combustion nozzle through the combustion module, gas and air injective into the combustion chamber 11 into the combustion chamber 11 in the combustion nozzle. The role of the circulating device 3 is to enter the crystal chamber 13 in the circulating line 32 in the drive down of the circulating fan 31 in the driving chamber, and is filtered by the exhaust gas filter plate 15 after filtering the mixing chamber 12 Inside, the gas and heat remaining in the exhaust gas are fully recovered.
[0054] As the gas pipeline 22 and the ignition branch 23, the gas is first entered into the ignition support 23 for ignition, and then combusts by the gas of the gas line 22.
[0055] The beneficial effect of the above technical solution: the burner provided by the present invention, through the circulating flow structure, achieving sufficient combustion of gas, and can also make full use of heat after burning, can greatly reduce the nitrogen-containing amount of combustion exhaust gas, saving Energy, and low nitrogen-containing exhaust gas can extend the life of the burner.
[0056] It will be noted in that it is intended to be the preferred embodiment of the present invention as described above, and is not intended to limit the invention, although the foregoing examples have been described in detail, and those skilled in the art will still It can be made to the embodiments described in the foregoing embodiments modifications, or to some technical features thereof Alternatively, any modification within the spirit and principle of the present invention, made, equivalent substitutions, improvements should be included in the The invention is within the scope of protection of the present invention.
