Description

Technical Field

[0001] This utility model relates to the field of energy and power engineering, specifically to a gas generator with preheating function. Background Technology

[0002] A gasifier is a reactor used to produce coal gas, water gas, and semi-water gas. The furnace body is cylindrical, with an outer shell made of steel plates or bricks, an inner lining of refractory bricks, and is equipped with feeding equipment, blast pipes, and gas pipes.

[0003] A Chinese patent with publication number CN101240195A discloses a gasifier with a two-stage combustion gasification function. This invention relates to a combustion furnace and a gasifier using solid fuel. It has a two-stage combustion gasification function. During the first combustion gasification, the fuel is dried, dehydrated, preheated, and then combusted and gasified. During the second combustion gasification, the volatiles, tar, and harmful gases released during the first combustion gasification are decomposed and gasified. Therefore, it can adapt to the combustion gasification of mineral or biomass fuels with high water content, varying sizes, irregular shapes, and low calorific value. It is also suitable for the mixed combustion gasification of mineral fuels and biomass fuels, and is particularly suitable for the incineration and utilization of municipal solid waste.

[0004] The aforementioned scheme, lacking preheating treatment before fuel combustion, results in lower fuel temperatures upon entering the furnace, slower coal temperature rise, and difficulty in releasing volatile components. This reduces the calorific value and yield of the gas. Furthermore, unpreheated coal undergoes incomplete gasification, leading to uneven gas composition, low combustion efficiency, and increased losses from incomplete combustion. Therefore, existing gasifiers lack suitable auxiliary mechanisms for fuel preheating.

[0005] The aforementioned solutions and existing technologies lack the necessary structural features, requiring improvement and optimization. Therefore, this invention proposes a gas generator with a preheating device to address the aforementioned problems. Utility Model Content

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figures 1 to 10 This utility model provides two technical solutions:

[0028] Example 1: A gas generator with preheating function includes a furnace body 1, a feed inlet 2, a base 3, a gas pipe 4, a blower pipe 5, an air inlet 6, an air outlet 7, and a grate 8. The feed inlet 2 is fixedly installed at the upper end of the furnace body 1, and the base 3 is fixedly installed at the lower end of the furnace body 1. The blower pipe 5 is fixedly installed on one side of the upper end of the furnace body 1, and the air inlet 6 and the air outlet 7 are fixedly installed on one side of the lower end of the furnace body 1. The grate 8 is fixedly installed at the upper end of the base 3. The grate 8 can support materials and also has a ventilation effect. The gas pipe 4 is fixedly installed on one side wall of the feed inlet 2, and the preheating auxiliary mechanism is fixedly connected to the top of the feed inlet 2. The preheating auxiliary mechanism includes a feed pipe 901, a coaxial double spiral pipe 902, a feeding port 903, an air inlet pipe 904, an exhaust pipe 905, and an air intake fan mechanism. One end of the feed pipe 901 is fixedly welded to the feeding port 2 for transporting fuel into the furnace body 1. The other end of the feed pipe 901 is fixedly welded to one end of the inner tube of the coaxial double spiral pipe 902, allowing fuel to enter the furnace body 1 from the inner tube of the coaxial double spiral pipe 902. The other end of the inner tube of the coaxial double spiral pipe 902 is fixedly welded to the bottom end of the feeding port 903. The upper opening of the feeding port 903 is larger than the lower opening, improving fuel input efficiency. The outer pipe of the coaxial double spiral pipe 902 is closed at both ends, with openings on both sides of its bottom end. These two openings are respectively connected to the air inlet pipe 904 and the exhaust pipe 905. One end of the air inlet pipe 904 is fixedly connected to the air intake fan mechanism, and one end of the exhaust pipe 905 is fixedly connected to the air outlet 7.

[0029] In actual use, fuel enters the coaxial double helix pipe 902 from the feed port 903, flows through the inner pipe to the feed pipe 901, and then enters the feed port 2 to reach the furnace body 1 for combustion. Because the fuel falls from a height and is impacted, it breaks up, increasing the contact area between coal and oxygen, thus promoting complete combustion and reducing harmful substances produced by incomplete combustion. The high-temperature environment in the furnace body 1 allows heated air to be drawn into the intake pipe 904 by the intake fan mechanism, passes through the outer pipe of the coaxial double helix pipe 902, and returns to the furnace body 1 through the exhaust pipe 905 for further heating, achieving circulation. The heated air moves upwards, while the fuel falls downwards, improving the utilization rate of the heated air. Simultaneously, the helical structure increases the time that heated air and fuel remain in the coaxial double helix pipe, increasing the fuel preheating time and improving the efficiency of the preheating process.

[0030] Example 2: Based on Example 1, the intake fan mechanism includes a magnesium alloy fan blade 906, a ceramic generator 907, a cylindrical shell 908, and a chassis 909. One end of the cylindrical shell 908 is open and fixedly connected to the intake pipe 904. One end of the chassis 909 is welded and fixedly connected to the intake port 6. The end face of the chassis 909 has three air intake holes 910, and the magnesium alloy fan blade 906 and the ceramic generator 907 are respectively arranged on both sides of the end face. A rotating shaft is provided on the ceramic generator 907, which passes through the chassis 909 and is connected to the magnesium alloy fan blade 906.

[0031] In actual use, within the high-temperature environment of the furnace body 1, the ceramic generator 907 utilizes the thermoelectric effect to directly convert heat energy into electrical energy. This electrical energy drives the rotating shaft to rotate the magnesium alloy fan blades 906, facilitating the rapid entry of heated air into the intake pipe 904. Simultaneously, the magnesium alloy material in the magnesium alloy fan blades 906 possesses high-temperature resistance, preventing damage to the fan blades from high temperatures.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
