In the description of the utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only a simplified description for the convenience of describing the utility model, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0037] Figure 1 This is a schematic diagram of an organic solid waste wet oxidation reactor according to an embodiment of the utility model. Figure 1 As shown, the organic solid waste wet oxidation reactor includes a support 1, a cylinder 2, a partition 3, a feed pipe 4 and a heating device 5.

[0038] The cylinder 2 is mounted on the bracket 1, and a accommodating chamber is arranged in the cylinder 2; the partition 3 is arranged in the accommodating chamber, and is fixedly connected to the inner wall of the cylinder 2, so as to divide the accommodating chamber into a connected heating chamber 21 and a retention chamber 22; the cylinder 2 is provided with a feed port, a discharge port and an exhaust port on one side of the retention chamber 22, and an air inlet and a sewage outlet are provided in the heating chamber 21 and the retention chamber 22; the discharge port is provided with a discharge valve 6, the air inlet port is provided with an air inlet valve 7, the exhaust port is provided with an exhaust valve 8, and the sewage outlet is provided with a sewage valve 9; the feed pipe 4 passes through the feed port and extends to the heating chamber 21, and a feed valve 10 is installed on the feed pipe 4; the heating device 5 is arranged in the heating chamber 21.

[0039] When in use, the material is transported into the heating chamber 21 through the feed pipe 4. With the continuous input of the material, the liquid level in the heating chamber 21 continues to rise. When the material is injected to the same height as the partition 3, it begins to cross the partition 3 and overflow to the retention chamber 22. When the material in the retention chamber 22 is injected to a certain height, the air inlet valve 7 is opened, and oxygen is injected into the cylinder 2 through the air inlet valve 7. At the same time, the heating device 5 is started to heat the material in the heating chamber 21. The material in the heating chamber 21 undergoes a preliminary oxidation reaction under the combined action of high temperature and oxygen. With the continuous injection of the material, the material that has undergone the preliminary oxidation reaction overflows through the partition 3 to the retention chamber 22 for further oxidation reaction. The product after the reaction is finally discharged from the cylinder 2 through the discharge valve 6. During the reaction, when too much gas is generated in the cylinder 2 and the air pressure in the cylinder 2 is too high, the exhaust valve 8 is opened to discharge the gas. When the gas is discharged and the air pressure in the cylinder 2 is restored to normal, the exhaust valve 8 is closed. After the oxidation reaction is completely completed, the waste valve 9 is opened to discharge the waste remaining in the cylinder 2.

[0040] By adopting the organic solid waste wet oxidation reactor of the utility model, viruses and bacteria in the organic solid waste are killed at high temperature, and the organic solid waste undergoes a wet oxidation reaction with oxygen in a high-temperature liquid phase environment to generate carbon dioxide, water, small-molecule organic acids, soluble salts, trace NH3 and other substances, while releasing heat. The reaction process does not require the occupation of a large amount of land, does not produce harmful substances to pollute the environment, has a short treatment cycle, and the final reaction product can also be used as a raw material for other industries, thereby realizing the harmless and resourceful treatment of organic solid waste.

[0041] like Figure 1 As shown, in this embodiment, the cylinder 2 is horizontally fixed on the bracket 1, and the partition 3 is fixedly connected to the bottom wall and the side wall of the inner wall of the cylinder 2, and maintains a certain distance from the inner wall of the top of the cylinder 2 to ensure that the material can overflow into the retention chamber 22 through the partition 3. Figure 1The right side of the middle partition 3 is a heating chamber 21, and the left side is a retention chamber 22. The length of the heating chamber 21 is about 2 / 5 of the total length of the cylinder 2, and the length of the retention chamber 22 is about 3 / 5 of the total length of the cylinder 2. The feed port is opened on the left side wall of the cylinder 2, and the feed pipe 4 extends into the retention chamber 22, including a serpentine pipe section and a straight pipe section. The straight pipe section penetrates the partition 3 and extends into the heating chamber 21, so that the material is injected into the heating chamber 21 through the feed pipe 4, and then overflows into the retention chamber 22 through the partition 3. By adjusting the opening of the feed valve 10, the flow rate of the material entering the accommodating chamber can be adjusted. The feed pipe 4 is set to pass through the retention chamber 22 first and then enter the heating chamber 21, so that the material in the feed pipe 4 can be preliminarily heated by the temperature of the material in the retention chamber 22 during the process of the material flowing through the retention chamber 22. The discharge port is provided at the bottom wall of the cylinder 2 near the feed port. By adjusting the opening of the discharge valve 6, the flow rate of the reacted material discharged from the accommodating chamber can be adjusted to ensure the residence time of the material in the cylinder 2, for example, the material is allowed to stay in the oxidation reactor for 20 minutes to 60 minutes. A plurality of air inlets are arranged at intervals along the length direction of the cylinder 2, and are arranged in both the heating chamber 21 and the residence chamber 22. By adjusting the opening of the air inlet valve 7, the amount of oxygen entering the accommodating chamber to participate in the oxidation reaction can be adjusted. The heating chamber 21 and the residence chamber 22 are also provided with a sewage outlet respectively, both of which are provided at the bottom wall of the cylinder 2. During the reaction, the sewage valve 9 is closed. After the reaction is completed, the sewage valve 9 is opened to discharge waste and clean the cylinder 2. According to the actual application, the specific structural form of the bracket 1, the specific shape and size of the cylinder 2 and the specific form of the feed pipe 4 can be adjusted, as long as the cylinder 2 can be stably supported and the material can be smoothly transported to the heating chamber 21 and overflow to the retention chamber 22. In order to smoothly carry out the oxidation reaction, the height of the partition 3 can be adjusted between 1 / 2-3 / 4 of the height of the cylinder 2, and the volume of the heating chamber 21 can be adjusted between 1 / 3-1 / 2 of the total volume of the accommodating chamber. The heating device 5 can be any heating structure, as long as it can stably heat the material in the cylinder 2. Through the heating device 5, the temperature of the material in the heating chamber 21 can reach 180℃-350℃, and at the same time, high-pressure air or oxygen-enriched air is introduced from the air inlet to maintain the pressure in the cylinder 2, so that oxygen has a higher solubility in the liquid phase, ensuring the smooth progress of the oxidation reaction.

[0042] The oxidation reaction between organic solid waste and oxygen in the liquid phase of the reactor is as follows:

[0043] Organic matter + O2 → CO2 + H2O + RCOOH;

[0044] Organic Cl+O2→Cl -1 +CO2+RCOOH;

[0045] Organic N+O2→NH3+CO2+RCOOH;

[0046] Sulfide + O2 → SO4 -2 ;

[0047] Phosphide + O2 → H 1-2 PO4 (-2)-(-1) ;

[0048] Organic B+O2→BO2 -1 +CO2+RCOOH.

[0049] Optionally, the organic solid waste wet oxidation reactor further includes a first liquid level gauge (not shown), a second liquid level gauge (not shown) and a controller. The first liquid level gauge is arranged in the heating chamber 21, and is used to monitor the fluid level in the heating chamber 21; the second liquid level gauge is arranged in the retention chamber 22, and is used to monitor the fluid level in the retention chamber 22; the input end of the controller is communicatively connected with the output ends of the first liquid level gauge and the second liquid level gauge, and the output end of the controller is communicatively connected with the control ends of the heating device 5, the feed valve 10, the discharge valve 6 and the air inlet valve 7. With this arrangement, the controller can judge the material injection situation through the liquid level height in the heating chamber 21 monitored by the first liquid level gauge and the liquid level height in the retention chamber 22 monitored by the second liquid level gauge, and then control the automatic start timing of the heating device 5 and the air inlet valve 7, and adjust the opening of the feed valve 10 and the discharge valve 6.

[0050] like Figure 1As shown, in this embodiment, the side walls of the cylinder 2 corresponding to the heating chamber 21 and the retention chamber 22 are respectively hinged with a delivery window 19, and the first liquid level gauge and the second liquid level gauge are respectively placed in the cylinder 2 through the delivery window 19. The first liquid level gauge monitors the liquid level in the heating chamber 21 in real time, and the second liquid level gauge monitors the liquid level in the retention chamber 22 in real time. The two transmit the monitoring results to the controller respectively. When the liquid level monitored by the first liquid level gauge is equal to the height of the partition 3, and the liquid level monitored by the second liquid level gauge reaches the first preset height, the controller controls the heating device 5 and the air inlet valve 7 to open, so that the material undergoes an oxidation reaction under the action of high temperature and oxygen. When the liquid level in the retention chamber 22 monitored by the second liquid level gauge reaches the second preset height (the second preset height is greater than the first preset height), it indicates that there is too much material in the retention chamber 22 at this time, and the controller can control to appropriately reduce the opening of the feed valve 10 and increase the opening of the discharge valve 6. During the normal operation of the reactor, materials are continuously input through the feed pipe 4. When the liquid level height in the heating chamber 21 monitored by the first liquid level meter is less than the third preset height (the third preset height is less than the height of the partition 3), it indicates that the operating power of the heating device 5 in the heating chamber 21 is too large, resulting in excessive evaporation of the material in the heating chamber 21, or there is a leak in the cylinder 2, or other faults occur. At this time, the controller controls the shutdown of the heating device 5, closes the feed valve 10 and the air inlet valve 7, and repairs the reactor. The controller controls the start and stop of the heating device 5 and the control logic of the opening of the feed valve 10, the discharge valve 6 and the air inlet valve 7 according to the liquid level height data monitored by the liquid level meter. It can be realized according to the existing mature algorithm, and its specific working principle will not be repeated here. According to the actual application situation, the liquid level meter can be selected from any specifications and models that can monitor the liquid level height.

[0051] Optionally, the organic solid waste wet oxidation reactor further includes a first thermometer 11 and a second thermometer 12. The first thermometer 11 is disposed in the heating chamber 21 to monitor the temperature of the fluid in the heating chamber 21; the second thermometer 12 is disposed in the retention chamber 22 to monitor the temperature of the fluid in the retention chamber 22; the output ends of the first thermometer 11 and the second thermometer 12 are respectively connected to the input end of the controller for communication. In this configuration, the controller can automatically adjust the operating power of the heating device 5 according to the temperature data monitored by the thermometer to ensure stable reaction.

[0052] like Figure 1As shown, in this embodiment, the first thermometer 11 extends into the material in the heating chamber 21 to monitor the temperature of the material in the heating chamber 21, and the second thermometer 12 extends into the material in the retention chamber 22 to monitor the temperature of the material in the retention chamber 22. The two respectively transmit the monitored temperature data to the controller in real time. The controller adjusts the operating power of the heating device 5 according to the temperature of the materials in the heating chamber 21 and the retention chamber 22, so that the material temperature is maintained within the temperature range required for the normal oxidation reaction. The oxidation reaction process is accompanied by an exothermic process. When the heat released by the oxidation reaction and the material temperature monitored by the thermometer are combined, and it is judged that the heat released by the reaction can make the oxidation reaction of the organic solid waste self-sustaining, the controller controls the heating device 5 to stop running. The control logic of the controller adjusting the operating power of the heating device 5 according to the temperature data can be realized according to the existing mature algorithm, and its specific working principle will not be repeated here. According to the actual application, the thermometer can be selected from any specifications and models that meet the monitoring material temperature.

[0053] Optionally, the organic solid waste wet oxidation reactor further includes a manometer 13, which is disposed in the containing chamber and is used to monitor the gas pressure in the containing chamber, and the output end of the manometer 13 is communicatively connected to the input end of the controller, and the output end of the controller is communicatively connected to the control end of the exhaust valve 8. With this arrangement, the controller can automatically control the opening and closing of the exhaust valve 8 according to the change in the gas pressure in the cylinder 2.

[0054] like Figure 1 As shown, in the present embodiment, the manometer 13 is installed at approximately the center position of the upper end of the cylinder 2. The manometer 13 monitors the gas pressure in the cylinder 2 in real time and transmits the air pressure data to the controller. When the air pressure data is greater than the first preset air pressure, the controller controls the exhaust valve 8 to open and discharge the gas in the cylinder 2. When the air pressure data drops below the first preset air pressure, the controller controls the exhaust valve 8 to close to ensure the high-pressure environment required for the oxidation reaction in the cylinder 2. The control logic of the controller controlling the opening and closing of the exhaust valve 8 according to the air pressure data can be realized according to the existing mature algorithm, and its specific working principle will not be repeated here. According to the actual application situation, the manometer 13 can be selected from any specifications and models that meet the requirements of monitoring the air pressure data in the cylinder 2.

[0055] Optionally, the cylinder 2 is provided with a pressure relief port, and a pressure relief valve 14 is installed at the pressure relief port, and the control end of the pressure relief valve 14 is communicatively connected with the output end of the controller. With this arrangement, when the exhaust valve 8 fails and cannot exhaust normally, resulting in excessive air pressure in the cylinder 2, the pressure relief valve 14 can be controlled to open for exhaust and pressure relief, thereby preventing the excessive pressure in the cylinder 2 from affecting the normal oxidation reaction.

[0056] like Figure 1As shown, in this embodiment, the cylinder 2 is provided with pressure relief ports on the upper side walls corresponding to the heating chamber 21 and the retention chamber 22, and a pressure relief valve 14 is installed in the pressure relief port. When the air pressure data in the cylinder 2 monitored by the pressure gauge 13 is greater than the second preset air pressure (the second preset air pressure is greater than the first preset air pressure), it indicates that the gas in the cylinder 2 cannot be normally discharged through the exhaust valve 8. At this time, the controller controls the pressure relief valve 14 to open, and the gas in the cylinder 2 is discharged through the pressure relief valve 14.

[0057] Optionally, the cylinder 2 is provided with a manual pressure relief port, and the manual pressure relief port is equipped with a manual pressure relief valve 15. With this arrangement, when the pressure relief valve 14 controlled to open and close by the controller fails, the timing of pressure relief can be manually controlled.

[0058] like Figure 1 As shown, in this embodiment, the manual pressure relief valve 15 is arranged on the side wall of the cylinder 2 corresponding to the top of the heating chamber 21 .

[0059] Optionally, the organic solid waste wet oxidation reactor further includes a stirring device 16, which includes a driving member 161, a stirring shaft 162, and a plurality of stirring blades 163. The driving member 161 is fixedly connected to the barrel 2; the stirring shaft 162 is drivingly connected to the output shaft of the driving member 161 and extends into the accommodating cavity; and the plurality of stirring blades 163 are fixedly connected to the circumference of the stirring shaft 162. The stirring device 16 is provided to stir the material in the barrel 2, and the stirring action makes the organic material evenly dispersed and evenly heated, thereby facilitating the oxidation reaction.

[0060] like Figure 1 As shown, in this embodiment, two groups of stirring devices 16 are arranged in the heating chamber 21 and the retention chamber 22 at intervals. The driving member 161 of the stirring device 16 can be a driving structure such as a motor, and is fixed to the outside of the cylinder 2. The output shaft of the driving member 161 is connected to the stirring shaft 162 to drive the stirring shaft 162 to rotate. The stirring shaft 162 extends into the heating chamber 21 and the retention chamber 22, and a plurality of stirring blades 163 are fixed circumferentially within the range below the material liquid level. When the material in the heating chamber 21 is at the same height as the partition 3, and the material in the retention chamber 22 reaches the first preset height, the controller controls the heating device 5 and the air inlet valve 7 to open, and controls the driving member 161 to start at the same time. The output shaft of the driving member 161 rotates to drive the stirring shaft 162 and the stirring blades 163 fixed to the stirring shaft 162 to rotate, thereby stirring the liquid phase material in the cylinder 2, so that the material is heated more fully and mixed more evenly with oxygen. According to actual application, the stirring blades 163 can be arranged in multiple layers in the extension direction of the stirring shaft 162, and the shape and size can also be adjusted. The stirring device 16 can also adopt other structural forms as long as it can fully stir the material in the barrel 2.

[0061] Optionally, the heating device 5 includes an electric heating tube 51 and a microwave generator 52. The electric heating tube 51 penetrates the cylinder 2 and extends into the heating cavity 21. The electric heating tube 51 is circumferentially sleeved with a sleeve; the microwave generator 52 is fixed to the inner wall of the heating cavity 21. The heating method combining the electric heating tube 51 and the microwave generator 52 can quickly make the material in the heating cavity 21 reach the temperature range required for the reaction at the initial stage of the reaction.

[0062] like Figure 1 As shown, the electric heating tube 51 is arranged horizontally in the heating chamber 21, and multiple tubes are arranged at intervals in the vertical direction, inserted from the right end of the cylinder 2, and each electric heating tube 51 is sleeved with a sleeve, and quartz sand and other materials are filled between the sleeve and the electric heating tube 51 to fix the electric heating tube 51 and conduct efficient heat conduction. During heating, the heat generated by the electric heating tube 51 is transferred to the material through the material in the sleeve and the sleeve. The setting of the sleeve avoids local overheating during heating, which causes coking and scaling on the surface of the electric heating tube 51. The material in the sleeve can be air, quartz sand or other heat-conducting materials. In order to ensure that the material in the heating chamber 21 completely immerses all the sleeves, the height of the top of the partition 3 is not less than 20 cm higher than the top of the uppermost sleeve, for example, it is set to 25 cm. There are two microwave generators 52, which are respectively fixed to the inner wall of the cylinder 2 above the heating chamber 21. In the initial stage of the reaction, in order to rapidly heat up the material in the heating chamber 21 , the electric heating tube 51 and the microwave generator 52 are turned on at the same time. When the material temperature rises to a preset temperature, only the electric heating tube 51 or only the microwave generator 52 can be turned on.

[0063] Optionally, the organic solid waste wet oxidation reactor further includes a backflush valve 17, which is connected to the exhaust valve 8. With this arrangement, when the exhaust valve 8 is blocked, air can be sent into the exhaust valve 8 through the backflush valve 17 to blow away the blockages such as dust in the exhaust valve 8 and keep the exhaust valve 8 unobstructed. The cooperation between the backflush valve 17 and the exhaust valve 8 is a mature prior art, and its specific internal structure will not be repeated here.

[0064] Optionally, an inspection door 18 is opened and closed on the side wall of the cylinder 2. The inspection door 18 is provided to facilitate maintenance personnel to enter the cylinder 2 for maintenance and inspection.

[0065] like Figure 1 As shown, in this embodiment, the inspection door 18 is arranged on the side wall of the cylinder 2 where the retention chamber 22 is located, and is hingedly connected to the cylinder 2. In normal state, the inspection door 18 is closed, and the inspection door 18 is opened when inspection and maintenance are required.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
