[0020] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and examples. It should be understood that the examples described herein are only used to explain the present application and do not limit the present application.

[0021] The present application provides a light quantum absolute oxygen flameless combustion kiln, the furnace body diameter of the light quantum absolute oxygen flameless combustion kiln is φ800mm, and the length is 14000mm. The furnace body is composed of a furnace tube, a feeding device 1 and a cooling device 5. The length of the furnace tube is 10m, wherein the lengths of the absolute oxygen dry distillation chamber 2, the alkane cracking chamber 3 and the reduction chamber 4 are 3m, 3m and 4m respectively. The lengths of the feeding device 1 and the cooling device 5 are both 2m. The furnace tube is made of 310S stainless steel, while the feeding device 1 and the cooling device 5 are made of 309S stainless steel.

[0022] The feeding device 1 is composed of a feeding screw conveyor, a hopper, a poking machine and a screw feeder. The poking machine is located below the hopper and above the furnace tube. The material falls on the screw feeder through the poking machine and is then pushed into the furnace tube. The cooling device 5 is composed of a cooling water tank, a cooling water pump and nozzles. The cooling water tank is used to store cooling water. The cooling water pump is used to pump the cooling water in the cooling water tank to the nozzles. The nozzles uniformly spray cooling water to cool the gas and the slag, so that the temperature is reduced to 200℃.

[0023] The three functional chambers in the furnace body perform different chemical reactions. The anaerobic dry distillation chamber 2 dry distills the material into slag and synthesis gas; the alkane cracking chamber 3 uses 200 trillion / s light quanta to excite C5-C19 alkanes in the synthesis gas, so that they are cracked into single C and H2; the reduction chamber 4 uses 160 trillion / s light quanta to excite C atoms, so that 2 electrons in the 2s orbital change from the ground state to the excited state, and one of them jumps into the 2p empty orbital, so that the C atom generates sp3 hybrid orbital and 2 H2 to synthesize CH4.

[0024] The furnace tube is heated by electricity. The temperature of the anaerobic dry distillation chamber 2 is controlled at 600-700℃, the temperature of the alkane cracking chamber 3 is controlled at 900-1000℃, and the temperature of the reduction chamber 4 is controlled at 700-750℃. The electric heating method in the furnace tube ensures accurate control of the reaction temperature, thereby improving the reaction efficiency and the purity of the product.

[0025] The cooling device 5 is provided with a discharge end, and the discharge end is provided with a purification system 6. The purification system 6 is composed of a slag collection barrel, a heat exchanger, a bubbling dust removal tower, a muddy water pressure filter, a gas filter cartridge, a paper filter cartridge, a vortex air pump induced draft fan, a gas storage tank, a residual gas combustion machine and an exhaust cylinder. The slag collection barrel is made of stainless steel and is detachable, and is used to collect slag; the bubbling dust removal tower has a diameter of φ400mm and a height of 1200mm, and two are connected in series, and is used to further purify the dust in the synthesis gas. The muddy water pressure filter has a pressure of 0.3MPa. The water is clear and is sent to the bubbling dust removal tower for circulation. The impurities in the water are filtered in the filter bag. The vortex air pump induced draft fan pumps the synthesis gas into the gas storage tank. The gas storage tank has two outlets. Part of the gas is sent to a methanol conversion and synthesis device through one outlet. The remaining gas is sent to a residual gas combustion machine through the other outlet. The combustion exhaust gas is discharged through the exhaust cylinder.

[0026] The methanol conversion and synthesis device adjusts the carbon-hydrogen ratio of CO and H2 in the synthesis gas to 1:2, removes CO2, and finally synthesizes methanol.

[0027] Example one (treatment of cow dung organic matter):

[0028] In this embodiment, cow dung is chosen as a representative of organic waste for treatment. Cow dung contains abundant organic matter, including cellulose, protein, fat, etc., and is a common type of agricultural waste.

[0029] First, the cow dung is pretreated to remove solid impurities and moisture, then it is fed into the furnace tube through the feeding screw conveyor. In the furnace tube, the cow dung is first dry-distilled in the anaerobic dry distillation chamber, decomposing into slag and synthesis gas. Subsequently, the synthesis gas enters the alkane cracking chamber, where C5-C19 alkanes are cracked into single C and H2 under the excitation of light quanta. Finally, the light quantum excitation in the reduction chamber makes the C atoms generate sp3 hybrid orbitals and synthesize CH4 with H2.

[0030] Under the electric heating mode in the furnace tube, the temperatures of the three functional chambers are precisely controlled within their respective optimal reaction temperature ranges. The temperature of the anaerobic dry distillation chamber is controlled at 600-700℃, the temperature of the alkane cracking chamber is controlled at 900-1000℃, and the temperature of the reduction chamber is controlled at 700-750℃. This temperature control ensures efficient reaction and improves the purity of the products.

[0031] After cooling by the cooling device, the temperature of the synthesis gas is reduced to below 200℃, then it enters the purification system. The slag collection barrel in the purification system collects the slag, and the bubble dust removal tower further purifies the dust in the synthesis gas. The water pressure filter press pressurizes the water to 0.3MPa, the effluent is clear and recycled, and the impurities are filtered in the filter bag. The vortex air pump blower sends the synthesis gas into the gas storage tank, and the two outlets of the gas storage tank send the gas into the methanol shift and synthesis device and the waste gas combustion machine, respectively. After the waste gas combustion machine burns the waste gas, it is discharged through the exhaust cylinder.

[0032] The methanol shift and synthesis device adjusts the carbon-hydrogen ratio of CO and H2 in the synthesis gas to 1:2 and removes CO2, finally synthesizing methanol. Through this series of processes, the organic matter in the cow dung is efficiently converted, not only reducing environmental pollution, but also producing high-value methanol products.

[0033] The first embodiment of the present invention demonstrates the application potential of the light quantum anaerobic flameless combustion kiln in treating agricultural waste. Through this technology, organic waste such as cow dung can be efficiently converted, not only solving the problem of waste disposal, but also providing a new way for the production of clean energy.

[0034] Example Two (Treatment of Organic Matter in Domestic Waste):

[0035] In this embodiment, domestic waste is chosen as a representative of organic waste for treatment. Domestic waste usually contains various organic matter, such as food residue, paper, plastic, etc., and is a common type of urban waste.

[0036] First, the household garbage is sorted to remove inorganic substances and recyclable items, then sent into the furnace tube through the feeding screw conveyor. In the furnace tube, the household garbage is first dry-distilled in the anaerobic dry-distillation chamber, decomposing into slag and synthesis gas. Subsequently, the synthesis gas enters the alkane cracking chamber, where C5-C19 alkanes are cracked into single C and H2 under the excitation of light quanta. Finally, the light quantum excitation in the reduction chamber makes C atoms generate sp3 hybrid orbitals and synthesize CH4 with H2.

[0037] Under the electric heating mode in the furnace tube, the temperatures of the three functional chambers are precisely controlled within their respective optimal reaction temperature ranges. The temperature of the anaerobic dry-distillation chamber is controlled at 600-700℃, the temperature of the alkane cracking chamber is controlled at 900-1000℃, and the temperature of the reduction chamber is controlled at 700-750℃. This temperature control ensures efficient reaction and improves the purity of the products.

[0038] After cooling by the cooling device, the temperature of the synthesis gas is reduced to below 200℃, and then it enters the purification system. The slag collection barrel in the purification system collects the slag, and the bubble dust removal tower further purifies the dust in the synthesis gas. The water pressure filter press pressurizes the water to 0.3MPa, the effluent is clear and recycled, and the impurities are filtered in the filter bag. The vortex air pump blower sends the synthesis gas into the gas storage tank, and the two outlets of the gas storage tank send the gas into the methanol shift and synthesis device and the waste gas combustion machine, respectively. After the waste gas combustion machine burns the waste gas, it is discharged through the exhaust cylinder.

[0039] The methanol shift and synthesis device adjusts the carbon-hydrogen ratio of CO and H2 in the synthesis gas to 1:2 and removes CO2, finally synthesizing methanol. Through this series of processes, the organic matter in household garbage is efficiently converted, not only reducing environmental pollution, but also producing high-value methanol products.

[0040] Example two of the present invention demonstrates the application potential of the light quantum anaerobic flameless combustion kiln in the treatment of municipal household garbage. Through this technology, organic waste such as household garbage is efficiently converted, not only solving the problem of waste disposal, but also providing a new way for the production of clean energy.

[0041] The present invention not only improves the conversion rate of organic waste and the yield of methanol, but also realizes the efficient utilization of waste, converting it into high-value methanol, while reducing the dependence on fossil fuels. In addition, the light quantum anaerobic flameless combustion technology of the present invention avoids the harmful gases and secondary pollution generated in the traditional combustion process, significantly reduces the energy consumption and greenhouse gas emissions in the production process, and meets the modern environmental protection concept, bringing green production advantages to enterprises.
