Description

Technical Field

[0001] The utility model relates to the technical field of gasifiers, and particularly relates to a water cooling component for a combustion chamber of a gasifier. Background Technique

[0002] A gasifier is a device that converts solid or liquid fuels into combustible gases and generates heat by burning these gases. Gasifiers can be divided into various types, including direct combustion gasifiers and indirect combustion gasifiers. The direct combustion gasifier directly burns the fuel to generate high-temperature gases, while the indirect combustion gasifier burns the fuel in an independent combustion chamber, and the generated high-temperature gases are transferred to the heating device through a heat exchanger. The high-temperature and high-pressure environment in the combustion chamber of the gasifier poses a severe challenge to the furnace body material, and long-term operation is prone to problems such as material fatigue, thermal stress concentration, and structural damage.

[0003] Currently, most gasifiers on the market mainly rely on traditional air cooling or natural heat dissipation methods for cooling the combustion chamber. These methods have problems such as limited cooling effect, high energy consumption, and difficulty in coping with extreme working conditions. Specifically, the traditional air cooling method relies on the air convection inside and outside the combustion chamber for heat exchange. However, in the high-temperature and high-pressure combustion environment, the heat capacity of air is limited, resulting in an insignificant cooling effect and uneven temperature distribution inside the furnace body, which affects the gasification reaction efficiency. The natural heat dissipation method is more dependent on the ambient temperature and the thermal conductivity of the furnace body material, and its cooling effect is more limited and cannot cope with the emergency of rapid temperature rise. Therefore, we need to propose a water cooling component for a combustion chamber of a gasifier. Content of the Utility Model

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a water cooling component for the combustion chamber of a gasifier, including a gasifier body 1, a C-shaped frame 2 is arranged inside the gasifier body 1, spray pipes 3 are fixedly connected to the inner walls on both sides of the C-shaped frame 2, and a plurality of groups of spray nozzles 4 are fixedly communicated with the outer wall of the spray pipe 3, and the plurality of groups of spray nozzles 4 are arranged at equal intervals.

[0023] In a further preferred embodiment, rotating rods 5 are respectively fixedly connected to the two side walls of the C-shaped frame 2, and one ends of the two groups of rotating rods 5 are respectively rotatably installed on the inner walls of the two sides of the gasifier body 1. One end of one group of rotating rods 5 penetrates through the gasifier body 1 and is connected to a driving motor 6.

[0024] Specifically, by setting the C-shaped frame 2, the spray pipe 3, the nozzle 4, the rotating rod 5 and the driving motor 6 to cooperate with each other, the combustion chamber inside the gasifier body 1 can be sprayed with water mist for cooling, and the spraying angle can be flexibly adjusted, which is beneficial to improving the cooling effect. A water-cooled wall 7 is fixedly installed inside the gasifier body 1, and a circulation assembly 8 for quickly reducing the temperature inside the gasifier body 1 is arranged on one side of the water-cooled wall 7.

[0025] In addition, by setting the water-cooled wall 7 and the circulation assembly 8 to cooperate with each other, the coolant continuously circulates inside the water-cooled wall 7, effectively reducing the temperature of the combustion chamber and preventing equipment damage or safety accidents caused by overheating. By simultaneously performing spray cooling and water circulation cooling inside the combustion chamber, it is beneficial to further improve the cooling effect of the combustion chamber, ensure the stable and reliable cooling effect, and improve the operation efficiency and safety of the gasifier;

[0026] In a further preferred embodiment, the circulation assembly 8 includes a circulation pipeline 801 which is fixedly embedded in the side wall of one side of the water-cooled wall 7. Both ends of the circulation pipeline 801 penetrate through the gasifier body 1 and are fixedly communicated with a cooling water tank 802. A circulation pump 803 is fixedly communicated with the side wall of one side of the cooling water tank 802;

[0027] By adopting the above case, by setting the circulation pipeline 801, the cooling water tank 802 and the circulation pump 803 to cooperate with each other, the circulation pipeline 801 ensures that the cooling water can continuously and stably circulate between the water-cooled wall 7 and the cooling water tank 802, thereby improving the heat transfer efficiency. This circulation method enables the cooling water to fully absorb the heat generated by the gasifier combustion chamber and take it away, effectively reducing the temperature of the combustion chamber.

[0028] Among them, the circulation pump 803 provides power for the circulation of the cooling water, ensuring the flow rate and flow volume of the cooling water in the pipeline, and further improving the cooling efficiency. The water-cooled wall 7, as the part directly in contact with the combustion chamber flame, can effectively absorb and take away the heat generated by the flame through the circulation of water, thereby protecting the furnace wall of the gasifier body 1 from high-temperature erosion. This protection method extends the service life of the gasifier body 1 and reduces the furnace wall damage and maintenance costs caused by high temperature;

[0029] Further, the circulation pump 803 is conductively connected to the circulation pipeline 801. A cooling component 9 for cooling the coolant is arranged inside the cooling water tank 802. By arranging the cooling component 9, the coolant inside the cooling water tank 802 can be quickly cooled, thereby improving the cooling effect on the combustion chamber of the gasifier body 1;

[0030] In a further preferred embodiment, the cooling component 9 includes a thermoelectric cooler 901. The thermoelectric cooler 901 is fixedly embedded in one side wall of the cooling water tank 802. A plurality of groups of heat dissipation fins 902 are fixedly connected to one side wall of the thermoelectric cooler 901. The refrigerating end of the thermoelectric cooler 901 is located inside the cooling water tank 802. A plurality of groups of heat dissipation fins 902 are all located outside the cooling water tank 802, and a plurality of groups of heat dissipation fins 902 are arranged at equal intervals;

[0031] The thermoelectric cooler 901 utilizes the Peltier effect and can quickly generate a refrigeration effect after being powered on, transferring heat from one side to the other side to achieve local cooling. This refrigeration method has the advantages of high refrigeration efficiency and fast response speed, and can effectively reduce the water temperature in the cooling water tank 802. The heat dissipation fins 902 can significantly improve the heat exchange efficiency by increasing the heat transfer area and enhancing the convection effect. When the cold generated by the thermoelectric cooler 901 is transferred to the water in the cooling water tank 802, the heat dissipation fins 902 can accelerate the heat exchange between the water and the air, thereby accelerating the water temperature drop rate.

[0032] Among them, the combined use of the thermoelectric cooler 901 and the heat dissipation fins can form an efficient cooling system. In this system, the thermoelectric cooler 901 is responsible for generating cold, while the heat dissipation fins 902 are responsible for quickly transferring the cold to the cooling water and taking away the heat through air convection. This combination method can significantly improve the cooling efficiency and reduce the temperature of the combustion chamber of the gasifier body 1;

[0033] In a further preferred embodiment, a liquid injection pipe 10 is fixedly connected to the top of the cooling water tank 802. The liquid injection pipe 10 is communicated with the inside of the cooling water tank 802. By arranging the liquid injection pipe 10, it is convenient for the staff to add coolant to the inside of the cooling water tank 802;

[0034] The driving motor 6 is fixedly installed on one side wall of the gasifier body 1. One end of the output shaft of the driving motor 6 is fixedly connected to one end of one group of rotating rods 5. The driving motor 6 is set as a forward and reverse stepping motor;

[0035] Specifically, the output shaft of the driving motor 6 can drive the rotating rod 5 to rotate, thereby driving the U-shaped frame 2 to rotate, so as to achieve the effect of swinging the spray pipe 3 and the nozzle 4 within a certain range, thereby adjusting the spraying angle, which is beneficial to improving the cooling effect;

[0036] A liquid inlet pipe 11 is fixedly embedded on one side wall of the gasifier body 1, and a flexible pipe 12 is fixedly connected to the bottom of the spray pipe 3. One end of the liquid inlet pipe 11 passes through the gasifier body 1 and is fixedly connected to one end of the flexible pipe 12. The staff connects the liquid inlet pipe 11 with the external water source in advance, and pumps the water source into the spray pipe 3 through a power pump. When the spray pipe 3 and the nozzle 4 are adjusted, the flexible pipe 12 can be used to keep the liquid inlet pipe 11 and the spray pipe 3 in a connected state.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
