[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a high aspect ratio, micro-pressurized pure oxygen continuous gasification furnace device. (Refer to...) Figure 1 and Figure 2 A high aspect ratio micro-pressurized pure oxygen continuous gasification furnace device includes a furnace body 1, an upper jacket 2, a lower jacket 3, and a temperature control component 4. The upper jacket 2 is fixedly fitted onto the upper half of the furnace body 1, and the lower jacket 3 is fixedly fitted onto the lower half of the furnace body 1. The upper jacket 2 and the lower jacket 3 have the same structure. The upper jacket 2 includes multiple cooling pipes 21 and two connecting pipes 22. The multiple cooling pipes 21 are arranged around the furnace body 1 and are all vertically arranged. The cooling pipes 21 are fixed to the outer wall of the furnace body 1. The two connecting pipes 22 are located at both ends of the cooling pipes 21, and each connecting pipe 22 is connected to all the cooling pipes 21. The connecting pipe 22 at the bottom of the cooling pipe 21 is connected to the water inlet pipe 23, which is used to introduce cooling water. The connecting pipe 22 at the top of the cooling pipe 21 is connected to the water outlet pipe 24, which is used to discharge cooling water. The temperature control component 4 is installed on the furnace body 1. The temperature control component 4 is used to measure the temperature values ​​of the middle gasification layer and the bottom ash layer inside the furnace body 1. The temperature control component 4 is used to control the flow rate of cooling water in the upper jacket 2 according to the temperature value of the middle gasification layer, and to control the flow rate of cooling water in the lower jacket 3 according to the temperature value of the bottom ash layer. When the temperature value increases, the temperature control component 4 controls the flow rate of cooling water to increase.

[0029] In use, cooling water is introduced into the connecting pipe 22 through the inlet pipe 23, and then flows into multiple cooling pipes 21 through the connecting pipe 22. The cooling water is discharged from the outlet pipe 24. During the flow, the cooling water cools the furnace body 1. The faster the flow rate of the cooling water, the better the cooling effect. Thus, the temperature control component 4 can adjust the cooling effect on the furnace body 1 by controlling the flow rate of the cooling water. At the same time, since the temperature control component 4 can measure the temperature values ​​of the middle gasification layer and the bottom ash layer inside the furnace body 1, the temperature control component 4 can adjust the flow rate of the cooling water in the upper jacket 2 according to the temperature value of the middle gasification layer, and can adjust the flow rate of the cooling water in the lower jacket 3 according to the temperature value of the bottom ash layer. This allows the cooling effect of the upper and lower parts of the furnace body 1 to be independently controlled, so that the overall cooling effect of the furnace body 1 can be adapted to its internal reaction temperature, which is beneficial to the gasification reaction inside the furnace body 1.

[0030] The distance between two adjacent cooling pipes 21 is 30-45mm. In practical applications, the distance between two adjacent cooling pipes 21 is determined by the gasification layer temperature required for powder combustion.

[0031] Specifically, refer to Figure 1 The temperature control component 4 includes a first temperature sensor 41, a first controller, a first water pump, a second temperature sensor 42, a second controller, and a second water pump. The first controller, the first water pump, the second controller, and the second water pump are not shown in the figure.

[0032] The first temperature sensor 41 is installed inside the furnace body 1 and located in the gasification layer area in the middle of the furnace body 1. The first temperature sensor 41 is used to output the first temperature signal at its location. The first controller is electrically connected to the first temperature sensor 41 and the first water pump respectively. The first water pump is installed on the water inlet pipe 23 of the upper jacket 2. The first controller responds to the first temperature signal and is used to control the pumping speed of the first water pump. When the first temperature signal increases, the pumping speed of the first water pump increases.

[0033] The second temperature sensor 42 is installed inside the furnace body 1 and located in the bottom ash layer area of ​​the furnace body 1. The second temperature sensor 42 is used to output the second temperature signal at its location. The second controller is electrically connected to the second temperature sensor 42 and the second water pump respectively. The second water pump is installed on the water inlet pipe 23 of the lower jacket 3. The second controller responds to the second temperature signal and is used to control the pumping speed of the second water pump. When the second temperature signal increases, the pumping speed of the second water pump increases.

[0034] The first temperature sensor 41 can measure the temperature value of the gasification layer in the middle of the furnace body 1 and output a first temperature signal. The first controller can control the pumping speed of the first water pump according to the first temperature signal. When the first temperature signal increases, the first controller can make the first water pump accelerate the pumping. The second temperature sensor 42 can measure the temperature value of the ash layer at the bottom of the furnace body 1 and output a second temperature signal. The second controller can control the pumping speed of the second water pump according to the second temperature signal. When the second temperature signal increases, the second controller can make the second water pump accelerate the pumping. Thus, the cooling effect of the upper and lower parts of the furnace body 1 can not only be independently controlled, but also dynamically controlled based on temperature changes.

[0035] Furthermore, referring to Figure 1 The first temperature sensor 41 and the second temperature sensor 42 are set in the same way in the furnace body 1. The first temperature sensor 41 is used as an example for detailed explanation.

[0036] The first temperature sensor 41 is provided in three layers, with 2-6 first temperature sensors 41 in each layer, and they are evenly arranged along the circumference of the furnace body 1. The first controller is electrically connected to all the first temperature sensors 41. Each first temperature sensor 41 is fitted with a temperature measuring tube 411. One end of the temperature measuring tube 411 is fixed to the inner wall of the furnace body 1, and the first temperature sensor 41 is located on the other end of the temperature measuring tube 411. The end of the temperature measuring tube 411 near the first temperature sensor 41 is closed and extends 50-100mm into the furnace body 1.

[0037] Reference Figure 1 In order to improve the water gas generation effect in the furnace body 1, the furnace body 1 is cylindrical box-shaped with a length-to-diameter ratio of 3.1-3.6. By setting the length-to-diameter ratio of the furnace body 1 between 3.1 and 3.6, the space for gasification reaction in the furnace body 1 is extended, providing more sufficient reaction time for water gas generation, thereby improving the water gas generation effect in the furnace body 1.

[0038] Reference Figure 1 and Figure 3 In order to facilitate the gasification reaction inside the furnace body 1, a feeder 5 is connected to the top of the furnace body 1. The feeder 5 supplies powder into the furnace body 1. A powder distributor 6 is installed inside the furnace body 1, which is directly opposite the feeder 5. The powder distributor 6 is composed of three or more conical spiral grooves and is fixedly connected to the inner wall of the furnace body 1.

[0039] When the feeder 5 adds powder into the furnace body 1, the powder can first fall onto the powder distributor 6. The overall conical powder distributor 6 can evenly disperse the powder entering the furnace body 1, so that the powder can continuously and evenly fall along the conical spiral groove of the powder distributor 6. Under the dispersing effect of the powder distributor 6, the powder is easy to be evenly added into the furnace body 1, making it easier for the powder to undergo gasification reaction.

[0040] Furthermore, referring to Figure 1 The feeder 5 is connected to the top of the furnace body 1 by a return gas pipe 51. The combustible gas flowing into the feeder 5 can be returned to the furnace body 1 through the return gas pipe 51. On the one hand, the combustible gas is discharged from the feeder 5, which can prevent the combustible gas from burning in the feeder 5. On the other hand, the combustible gas can be burned in the furnace body 1 to supplement the internal temperature of the furnace body 1. The temperature inside the furnace body 1 does not need to be provided by the combustion of powder, which increases the proportion of powder gasification and improves the effective utilization rate of powder.

[0041] Reference Figure 1 In order to make it easy to add powder evenly in the feeder 5, a large distributor 52 is connected to the feeder 5. A strip screen 53 is set at the connection between the large distributor 52 and the feeder 5. Through the strip screen 53, the powder is easily and evenly added to the feeder 5 by the large distributor 52, so that the powder can be evenly distributed in the feeder 5.

[0042] Reference Figure 1 To further facilitate the gasification reaction within the furnace body 1, a grate 7 is connected to the bottom of the furnace body 1. A gasifying agent distributor 8 is installed below the grate 7. The gasifying agent distributor 8 includes an inlet pipe 81 and an exhaust pipe 82. The inlet pipe 81 is used to introduce the gasifying agent and is fixedly connected to the furnace body 1. Multiple exhaust pipes 82 are provided, with one end of each pipe connected together in a divergent manner. The other end of each exhaust pipe 82 faces the grate 7, and the common connection point of the multiple exhaust pipes 82 is connected to the inlet pipe 81.

[0043] When the gasifying agent flows through the inlet pipe 81 to the outlet pipe 82, the multiple outlet pipes 82 arranged in a divergent manner can evenly introduce the gasifying agent into the furnace body 1, thereby enabling the gasifying agent to enter the furnace body 1 evenly.

[0044] Reference Figure 1 In order to facilitate the discharge of ash and slag from the grate 7, the bottom of the furnace body 1 is connected to an ash hopper 9. The top of the ash hopper 9 and the bottom of the furnace body 1 are connected to a pressure relief pipe 91. The gas between the ash hopper 9 and the grate 7 can be discharged through the pressure relief pipe 91, so that the ash and slag on the grate 7 are not difficult to discharge due to gas pressure. At the same time, the pressure relief pipe 91 can allow the gas to be reintroduced into the furnace body 1 for reaction.

[0045] Reference Figure 1To facilitate the gasification reaction within the furnace body 1, a pressurized gas pipe 10 is connected to the middle of the furnace body 1. The pressurized gas pipe 10 is connected to an air pump 101, which introduces air into the furnace body 1 through the pressurized gas pipe 10 to regulate the gas pressure inside the furnace body 1. By regulating the gas pressure inside the furnace body 1, it is possible to maintain a slightly pressurized state inside the furnace body 1, for example, to achieve a gas pressure of 0.19 MPa. Compared with an atmospheric pressure gasifier, the slightly pressurized state inside the furnace body 1 is beneficial to improving the gasification reaction rate and accelerating the production efficiency of water gas.

[0046] Furthermore, referring to Figure 1 A pressure sensor 102 is installed on the inner wall of the furnace body 1. The pressure sensor 102 is used to output the pressure signal inside the furnace body 1. The pressure sensor 102 is electrically connected to a third controller 103. The third controller 103 is fixed to the air pump 101. The third controller 103 is electrically connected to a first electrically controlled valve 104 and a second electrically controlled valve 105. An exhaust pipe 106 is connected to the pressurized air pipe 10. The first electrically controlled valve 104 is installed on the pressurized air pipe 10, and the second electrically controlled valve 105 is installed on the exhaust pipe 106. The third controller 103 responds to the pressure signal and is used to control the opening and closing of the first electrically controlled valve 104 and the second electrically controlled valve 105. When the pressure signal is greater than the preset pressure value, the third controller 103 controls the first electrically controlled valve 104 to close and controls the second electrically controlled valve 105 to open.

[0047] Under the pressurization action of the air pump 101, when the air pressure value inside the furnace body 1 is greater than the preset air pressure value, the third controller 103 can control the first electrically controlled valve 104 to close and the second electrically controlled valve 105 to open based on the air pressure signal, so that the airflow of the air pump is discharged from the exhaust pipe 106 and the pressurization inside the furnace body 1 is stopped. When the air pressure value inside the furnace body 1 is not greater than the preset air pressure value, the third controller 103 can control the first electrically controlled valve 104 to open and the second electrically controlled valve 105 to close based on the air pressure signal, so that the airflow of the air pump flows into the furnace body 1 from the pressurized air pipe 10 to pressurize the furnace body 1, thereby realizing the automatic control of the air pressure inside the furnace body 1.

[0048] The implementation principle of a high aspect ratio micro-pressurized pure oxygen continuous gasification furnace device according to an embodiment of this application is as follows: During use, the first temperature sensor 41 measures the temperature of the gasification layer in the middle of the furnace body 1, the first controller controls the pumping speed of the first water pump according to the first temperature signal, the second temperature sensor 42 measures the temperature of the bottom ash layer in the furnace body 1, and the second controller controls the pumping speed of the second water pump according to the second temperature signal. Under the independent cooling effect of the upper jacket 2 and the lower jacket 3, the overall cooling effect of the furnace body 1 can automatically adapt to the internal reaction temperature, which is conducive to the gasification reaction in the furnace body 1.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
