Description

Technical Field

[0001] This utility model belongs to the field of energy and power engineering technology, and more specifically, it relates to a novel coal-to-gas burner. Background Technology

[0002] Driven by the profound adjustment of the global energy structure and the "dual carbon" goal, the clean and efficient utilization of coal has become a core issue in the energy field. Traditional coal combustion methods, due to their low efficiency and serious pollution, are unable to meet the requirements of modern industry and environmental protection. As a key device for the clean transformation of coal, the new coal-to-gas burner provides low-carbon solutions for industrial heating, power generation and other fields by converting solid coal into gaseous fuel and achieving efficient combustion. Its working principle runs through the entire process of coal gasification, gas purification, efficient combustion and pollutant control, and its core technology is reflected in the cross-disciplinary application and system integration optimization.

[0003] The existing application number is CN202121266944.5. This utility model belongs to the field of burner technology, and in particular to a pulverized coal and gaseous fuel co-firing burner for rotary kilns. It includes a burner body, inside which a central air channel pipe and a swirl air channel are respectively arranged from the inside out. This utility model uses a corrugated compensator between the burner body and the outer casing pipe. By rotating the adjusting screw, the relative position between the outer casing pipe and the burner body is adjusted, thereby changing the cross-sectional area of ​​the inclined plate in the swirl air channel, thus controlling the amount of pulverized coal and consequently the flame size. The swirl air channel, central air channel pipe, and outer clean air pipe within the burner body assist in the mixed combustion of pulverized coal or gas, making combustion more complete and uniform, and improving combustion efficiency. A first valve and a second valve are installed on the surface of both the pulverized coal / gas inlet pipe and the outer clean air pipe to adjust and control the inflow, facilitating adjustment and control according to the combustion conditions of the rotary kiln.

[0004] Based on the above, to ensure the safety of existing coal-to-gas burners, when starting the burner, the worker generally needs to open the air valve first, and then open the coal-to-gas valve. When shutting down the burner, the worker needs to close the coal-to-gas valve first, and then close the air valve. However, many workers, in order to save time, usually close both the air and coal-to-gas valves at the same time. The sudden interruption of the air supply may result in residual gas in the gas pipeline (especially when the pipeline is long or the pressure is high), causing a small amount of gas to form a high-concentration combustible mixture in the combustion chamber or pipeline. This mixture is prone to smoldering or backfire due to high temperature, posing a certain safety hazard. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a novel coal-to-gas burner. This addresses the issue that existing coal-to-gas burners, when used safely, typically require workers to first open the air valve and then the coal-to-gas valve during startup, and then close the coal-to-gas valve and then the air valve during shutdown. However, many workers, for convenience, often close both the air and coal-to-gas valves simultaneously, causing a sudden interruption of the air supply. This results in residual gas in the gas pipeline (especially when the pipeline is long or the pressure is high), leading to a small amount of gas forming a high-concentration combustible mixture in the combustion chamber or pipeline. This mixture is prone to smoldering or backfire due to high temperatures, posing a safety hazard.

[0006] The purpose and effectiveness of this novel coal-to-gas burner are achieved through the following specific technical means:

[0007] A novel coal-to-gas burner includes a burner body, a combustion chamber, a combustion nozzle, an air inlet filter chamber, a combustion inlet pipe, an operating baffle, a filtering and turbulence-disrupting mechanism, and a safety protection mechanism. The combustion chamber is fixedly connected to the left side of the burner body. The combustion nozzle is fixedly connected to the left side of the combustion chamber via a flange. The air inlet filter chamber is fixedly connected to the lower part of the combustion chamber via a flange. Two sets of combustion inlet pipes are provided, each fixedly connected to the lower part of the air inlet filter chamber. One set of combustion inlet pipes is connected to an air inlet pipeline, and the other set is connected to a coal-to-gas pipeline. A valve structure is provided at the front end of each set of combustion inlet pipes. Two sets of operating baffles are provided, each positioned in front of the valve on the combustion inlet pipe. The filtering and turbulence-disrupting mechanism is located inside and above the air inlet filter chamber. The safety protection mechanism is located outside the operating baffle.

[0008] Furthermore, the filtering and turbulence-disrupting mechanism includes: a turbulence-disrupting plate; multiple sets of turbulence-disrupting plates are provided, and the multiple sets of turbulence-disrupting plates are respectively fixedly connected to the inside of the combustion chamber.

[0009] Furthermore, the filtration and turbulence-disrupting mechanism also includes: an activated carbon adsorbent and a ceramic filter membrane; the activated carbon adsorbent is fixedly connected to the inside of the air intake filtration chamber; the ceramic filter membrane is fixedly connected to the inside of the air intake filtration chamber and is disposed below the activated carbon adsorbent.

[0010] Furthermore, the safety protection mechanism includes: a protective fixing plate and a protective limiting component; the protective fixing plate is fixedly connected to the lower part of the air intake filter chamber; the protective limiting component is fixedly connected to the front end of the protective fixing plate, and two sets of operating shields are slidably connected to the left and right sides inside the protective limiting component respectively.

[0011] Furthermore, the safety protection mechanism also includes: a first connecting spring, a second connecting spring, a protective guide wheel, and a protective transmission rope; the first connecting spring is fixedly connected inside the protective limiting member, and the lower end of the first connecting spring is fixedly connected to a set of operating shields on the right side; the second connecting spring is fixedly connected inside the protective limiting member, and the lower end of the second connecting spring is fixedly connected to a set of operating shields on the left side, and the elastic force of the second connecting spring is less than the elastic force of the first connecting spring; the protective guide wheel is rotatably connected to the upper end of the protective limiting member; the protective transmission rope is wrapped around the outer circumference of the protective guide wheel, and the lower end of the protective transmission rope is fixedly connected to the operating shields respectively.

[0012] Furthermore, the safety protection mechanism also includes: a protective drive component and a protective magnetic block; the protective drive component is fixedly connected to the upper right side inside the protective limiting component, the protective drive component is an electromagnet structure, and the protective drive component is connected in series with the igniter circuit inside the combustion chamber; the protective magnetic block is fixedly connected above a set of operating shields on the right side, and the protective magnetic block is magnetically connected to the protective drive component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the setting of a filter turbulence mechanism, achieves the filtration effect of coal-to-gas through the combined action of activated carbon adsorption and ceramic filter membrane, avoiding combustion nozzle clogging and sulfur corrosion, ensuring combustion stability, and the turbulence plate achieves the turbulence effect of coal-to-gas, allowing the coal-to-gas to burn completely, thus improving the overall performance of the burner.

[0015] This invention, through the inclusion of a safety protection mechanism, allows the worker to activate the igniter. The igniter circuit connects to the circuit of the protective drive component, generating magnetism that attracts a protective magnetic block. This attraction causes the magnetic block to move upwards, which in turn moves a set of operating baffles on the right side upwards. Under the action of the protective guide wheel and the protective transmission rope, the two sets of operating baffles move in opposite directions, blocking the air intake valve. At this point, the worker can open the coal-to-gas valve. When closing the valve, the worker must first close the coal-to-gas valve, then turn off the igniter. After the operating baffles reset, the worker can then close the air intake valve. This standardized operation, prevents workers from improperly closing the valve, reduces the risk of smoldering and backfire, and improves the overall safety of the burner.

[0030] Example 2:

[0031] This utility model provides a novel coal-to-gas burner, based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes a safety protection mechanism, which is located on the outside of the operation shield 6.

[0032] The safety protection mechanism includes a protective fixing plate 601 and a protective limiting member 602.
