[0041] Figure 1 This is a schematic diagram of a livestock and poultry manure oxidation reaction system according to an embodiment of the utility model. Figure 1 As shown, the livestock and poultry manure oxidation reaction system includes a first conveying pipeline 1, a second conveying pipeline 2, a third conveying pipeline 3, a feed pipe 4, a discharge pipe 5, an air intake pipe 6, a heating device 7 and a bracket 8.

[0042] The feed port of the second conveying pipeline 2 is connected to the discharge port of the first conveying pipeline 1 through the first connecting pipe 9; the feed port of the third conveying pipeline 3 is connected to the discharge port of the second conveying pipeline 2 through the second connecting pipe 10; the feed pipe 4 is connected to the feed port of the first conveying pipeline 1, and a feed valve is installed on the feed pipe 4; the discharge pipe 5 is connected to the discharge port of the third conveying pipeline 3, and an exhaust port 501 is provided in the discharge pipe 5, and a discharge valve is installed on the discharge pipe 5; the first conveying pipeline 1, the second conveying pipeline 2 and the third conveying pipeline 3 are all connected to the air intake pipe 6, and an air intake valve is installed on each air intake pipe 6; the first conveying pipeline 1, the second conveying pipeline 2 and the third conveying pipeline 3 are all provided with a heating device 7; the first conveying pipeline 1, the second conveying pipeline 2 and the third conveying pipeline 3 are all mounted on the bracket 8.

[0043] When in use, the heating device 7 is started, the feed valve, the discharge valve and each air inlet valve are opened, and the material with a solid content of 3%-10% is transported to the first conveying pipeline 1 through the feed pipe 4. Then the material is transported to the second conveying pipeline 2 and the third conveying pipeline 3 connected thereto through the first conveying pipeline 1. In the process of flowing through each conveying pipeline, the material is heated by each heating device 7, so that the virus and bacteria are killed by high temperature, and at the same time, it is fully mixed with the oxidant entering through each air inlet pipe 6, and an oxidation reaction occurs. The fully reacted material is discharged through the discharge pipe 5, and the generated carbon dioxide and other gases are discharged through the exhaust port 501 on the discharge pipe 5. During the reaction process, by adjusting the operating power of the heating device 7 on each conveying pipeline, the material in each conveying pipeline can be heated to different temperatures to carry out oxidation reactions at different stages. By adjusting the opening of the feed valve, the discharge valve and the air inlet valve, the migration speed of the material in the conveying pipeline and the degree of sufficiency of the material mixing with oxygen to undergo oxidation reaction under high temperature environment can be adjusted.

[0044] By adopting the livestock and poultry manure oxidation reaction system of the utility model, the heating device 7 is used to heat the material, so that the virus and bacteria are eliminated in a high temperature environment. At the same time, the material undergoes an oxidation reaction with the injected oxidant in the high temperature environment to generate harmless gases such as carbon dioxide and water vapor, as well as products that can be used as raw materials for other industries. No harmful substances will be generated to pollute the environment, and the harmless and resource-based treatment of organic solid waste is achieved. The treatment cycle is short, and the material is continuously input to react without occupying a large amount of land.

Figure 1The lowermost one is the first conveying pipeline 1, the middle one is the second conveying pipeline 2, and the uppermost one is the third conveying pipeline 3. The material enters the first conveying pipeline 1 through the feed pipe 4, gradually moves upward and fills the second conveying pipeline 2 and the third conveying pipeline 3. In order to make the oxidation reaction proceed in stages, the operating power of each heating device 7 can be adjusted, so that the power of the heating device 7 on the first conveying pipeline 1 is less than that of the second conveying pipeline 2, and the power of the heating device 7 on the second conveying pipeline 2 is less than that of the third conveying pipeline 3, to ensure that as the material moves, the temperature in each conveying pipeline increases step by step, so that the material temperature in the first conveying pipeline 1 is less than 150°C, the material temperature range in the second conveying pipeline 2 is 150°C-200°C, and the material temperature range in the third conveying pipeline 3 is 200°C-230°C. At the same time, the oxygen content of the oxidant injected into the first conveying pipeline 1, the second conveying pipeline 2 and the third conveying pipeline 3 through each air inlet pipe 6 is 5%-10%, 10%-20%, 10%-20% of the COD value of livestock and poultry manure, respectively, and can be specifically set to 10%, 20%, and 20%, respectively. By matching and adjusting the opening of the feed valve and the discharge valve, the residence reaction time of the material in each conveying pipeline can be controlled, for example, the material is allowed to stay in the conveying pipeline for 10 minutes. The livestock and poultry manure oxidation reaction system of the utility model is a plug flow reaction system, and the short circuit and back mixing of the material are small. According to the actual application situation, the heating device 7 can be any heating structure, as long as it can stably heat each conveying pipeline and make the material in each conveying pipeline reach the set temperature, and the bracket 8 can be any structural form, as long as it can integrate and set up each conveying pipeline to save floor space.

Wall thermometers are respectively arranged on each conveying pipeline, which are respectively used to monitor the temperature of the side walls of the first conveying pipeline 1, the second conveying pipeline 2 and the third conveying pipeline 3. Each material thermometer 11 transmits the material temperature data at each monitored position to the controller respectively, and each wall thermometer transmits the side wall temperature data of each conveying pipeline to the controller respectively. The controller comprehensively judges the heat exchange efficiency in the first conveying pipeline 1 according to the temperature of the material in the first conveying pipeline 1 before heating, the temperature after flowing through the first conveying pipeline 1 and the temperature of the side wall of the first conveying pipeline 1, and then appropriately adjusts the working efficiency of the heating device 7 installed on the first conveying pipeline 1, and at the same time matches and adjusts the opening of the feed valve, the discharge valve and the intake valve to ensure that the material has sufficient residence time in each conveying pipeline under different temperature environments and has sufficient mixing reaction time with oxygen. Similarly, the controller comprehensively judges the heat exchange efficiency in the second conveying pipeline 2 according to the temperature of the material before entering the second conveying pipeline 2, the temperature after flowing through the second conveying pipeline 2 and the temperature of the side wall of the second conveying pipeline 2, and then appropriately adjusts the working efficiency of the heating device 7 installed on the second conveying pipeline 2; comprehensively judges the heat exchange efficiency in the third conveying pipeline 3 according to the temperature of the material before entering the third conveying pipeline 3, the temperature after flowing through the third conveying pipeline 3 and the temperature of the side wall of the third conveying pipeline 3, and then appropriately adjusts the working efficiency of the heating device 7 installed on the third conveying pipeline 3. The controller comprehensively judges and adjusts the working efficiency of the heating device 7 and the control logic of the opening of the feed valve, the discharge valve and the intake valve according to the material temperature at each position and the side wall temperature of each conveying pipeline. It can be realized according to the existing mature algorithm, and its specific working principle will not be repeated here.
