Abstract
Description
Technical Field
[0001] This utility model relates to the field of gasification furnace technology, specifically to a rapidly cooling burner. Background Technology
[0002] A gasifier is a device that converts solid or liquid fuels into combustible gases through high-temperature thermochemical reactions. Its core principle is to convert carbonaceous materials such as biomass, coal, and waste into syngas, primarily composed of carbon monoxide, hydrogen, and methane, using reactions such as pyrolysis, oxidation, and reduction under oxygen-deficient or oxygen-limited conditions. The gasifier burner is a crucial component, used to control the mixing and injection of fuel and gasifying agents (such as air, oxygen, and steam) to ensure efficient and stable gasification. Since burners are typically made of metal or ceramic materials, prolonged exposure to the high temperatures of the flame or the gasification reaction environment can lead to material softening, deformation, or oxidation corrosion. Cooling can extend the burner's lifespan, and excessively high burner temperatures can cause premature fuel combustion, disrupting the distribution of the reaction zone within the gasifier, affecting gasification efficiency, or producing unstable flames. Existing burners mostly use internal water channels to circulate water and remove excess heat, thus lowering the burner's temperature. However, relying solely on internal water circulation to remove heat is inefficient, and the temperature of the outer surface is difficult to lower. Therefore, a burner with rapid cooling is designed to solve these problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5This utility model provides a technical solution: a rapidly cooling burner, comprising: a cooling circulation mechanism 1 and a burner mechanism 2. The cooling circulation mechanism 1 includes a circulating water tank 11, a heat exchanger 12, a gas-liquid separator 13, and a steam buffer tank 14. The outlet of the circulating water tank 11 and the heat exchanger 12 are connected by a pipe. The inlet of the heat exchanger 12 and the outlet of the gas-liquid separator 13 are connected by a pipe. A water pump is connected to the pipe connecting the heat exchanger 12 and the gas-liquid separator 13. The outlet of the gas-liquid separator 13 is connected to the interior of the steam buffer tank 14 by a pipe. An air pump is connected to the pipe connecting the gas-liquid separator 13 and the steam buffer tank 14. An air pump is fixedly connected to the outlet at the upper end of the steam buffer tank 14. The burner mechanism 2 includes a burner body 21, an outer heat dissipation layer 22, and a surface heat dissipation layer 23. The outer heat dissipation layer 22 is sleeved on the outside of the burner body 21, and the surface heat dissipation layer 23 is sleeved on the lower outer side of the outer heat dissipation layer 22. A heat dissipation pipe 24 is installed inside the outer heat dissipation layer 22. The surface heat dissipation layer 23 is hollow inside and has nozzles 25 arranged in an array inside. The upper outer side of the surface heat dissipation layer 23 is fixedly connected to the gasifier. The upper air outlet of the steam buffer tank 14 is connected to the upper air inlet of the surface heat dissipation layer 23 through a pipe. The water outlet of the circulating water tank 11 is connected to the water inlet of the heat dissipation pipe 24 inside the outer heat dissipation layer 22 through a pipe. The water outlet of the heat dissipation pipe 24 is connected to the water inlet at the front end of the gas-liquid separator 13 through a pipe.
[0025] In use, the circulating water tank 11 uses a water pump to transfer water to the inlet on the outside of the outer heat dissipation layer 22 and into the heat dissipation pipe 24. After circulating once, the water is discharged through the drain outlet of the heat dissipation pipe 24 and enters the gas-liquid separator 13. Inside the gas-liquid separator 13, high-temperature steam is discharged through the steam outlet, while excess water is sent into the heat exchanger 12 through the pipe on the right and the water pump. After cooling, the water is discharged back into the circulating water tank 11. The gas discharged from the gas-liquid separator 13 is sent into the steam buffer tank 14 through the air pump. Excess gas is discharged through the pressure relief valve of the steam buffer tank 14. When the surface also needs to be cooled, the air pump on the steam buffer tank 14 is started, and the gas is discharged through the pipe to the cavity inside the surface heat dissipation layer 23 and then sprayed out through the nozzle 25 onto the surface of the outer heat dissipation layer 22, so that the surface cools down quickly. Combined with the internal heat dissipation pipe 24 to cool the interior, the overall temperature drops rapidly.
[0026] like Figure 1-3 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a pressure sensor 31 is installed in the pipe connecting the steam buffer tank 14 and the surface heat dissipation layer 23. The pressure sensor 31 is electrically connected to the control terminal.
[0027] Analysis of the above structure shows that the speed of the air pump is controlled by the data from the air pressure sensor 31 to prevent the air pressure from being too high or too low during delivery.
[0028] like Figure 1-3 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a heating swirl tube 32 is installed at the lower end of the gas-liquid separator 13, and the heating swirl tube 32 is electrically connected to the control terminal.
[0029] Analysis of the above structure shows that when the steam volume is insufficient, the heating swirl tube 32 can be activated to heat the water inside the gas-liquid separator 13, thereby increasing the steam volume.
[0030] like Figure 1-5 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a temperature sensor is fixedly connected to the lower inner side of the burner body 21, and the temperature sensor is electrically connected to the control terminal.
[0031] Analysis of the above structure shows that when the temperature of the burner body 21 is too high, the power of the water pump inside the circulating water tank 11 and the steam pump on the steam buffer tank 14 will be increased to help the burner body 21 quickly reduce its temperature.
[0032] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the nozzle 25 is arranged in a spiral array inside the surface heat dissipation layer 23 and is generally conical.
[0033] Analysis of the above structure shows that the spiral array of nozzles 25 can make the spraying range more uniform, while the overall conical shape of nozzles 25 can reduce the pressure when spraying, making the spray pressure more uniform and reducing clogging.
[0034] like Figure 1-5 As shown, this utility model embodiment provides an implementation method in which the opening angle of the nozzle 25 is tangent to the outer side of the outer heat dissipation layer 22.
[0035] Analysis of the above structure shows that the opening angle of the nozzle 25 is tangent to the outer side of the outer heat dissipation layer 22, which causes the steam to form a vortex on the surface of the outer heat dissipation layer 22, making the cooling more uniform and increasing the probability of adhering to the surface.
[0036] like Figure 1-5 As shown in the figure, this utility model embodiment provides an implementation method in which the cooling circulation mechanism 1 contains ultrapure water.
[0037] Analysis of the above structure shows that the cooling circulation mechanism 1 contains ultrapure water, which can greatly reduce the situation of scale clogging the nozzle 25.
