Abstract
Description
Technical Field
[0001] This invention relates to the field of chemical equipment technology, specifically to a supercritical carbonization production equipment for solid materials. Background Technology
[0002] In chemical production, the treatment of solid materials using supercritical fluid technology requires a high-temperature, high-pressure environment; for example, supercritical carbon dioxide fluid is used to treat steel slag. Currently, batch reactors are used to process solid materials using supercritical fluid technology.
[0003] However, during operation, the entire reactor body is under a closed, high-pressure state. Its inherent drawback is that each feeding and discharging operation requires depressurizing, opening, and resealing the entire reactor before pressurizing it back to operating conditions. This process not only leads to complete production interruption, significantly reducing efficiency, but the repeated pressurization and depressurization cycles also consume a large amount of energy, making it difficult to meet the demands of large-scale industrial continuous production.
[0004] Therefore, how to improve the production efficiency of solid materials and reduce production energy consumption has become an urgent technical problem to be solved. Summary of the Invention

Attached Figure Description
[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0018] Figure 1 This is a schematic diagram of the structure of a supercritical carbonization production equipment for solid materials provided in an embodiment of the present invention. Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0020] Figure 1 This is a schematic diagram of the structure of a supercritical carbonization production equipment for solid materials provided in an embodiment of the present invention. Figure 1As shown, this supercritical carbonization production equipment for solid materials includes: a material transfer system 11, a first fluid system 12, a second fluid system 13, and a control system (…). Figure 1 (Not shown in the image).
[0021] The material transfer system 11 is a physical carrier that transports solid materials from an atmospheric pressure environment to a high-pressure reaction environment and then back to an atmospheric pressure environment. In this embodiment, the material transfer system 11 includes a series of containers connected in series and a switching device disposed therebetween. Specifically, the material transfer system 11 may include, in sequence along the material processing path, a feeding hopper 104, a pressurized transition hopper 101, a reaction hopper 102, a depressurized transition hopper 103, and a discharge hopper 105.
[0022] The feed hopper 104 is used to fill the pressurized transition hopper with the solid material to be reacted. The pressurized transition hopper 101 is used to fill the reaction hopper 102 with the solid material stored inside when its internal pressure reaches and is maintained at a target pressure matching the internal pressure of the reaction hopper 102. The reaction hopper 102 is used to react the solid material with the reaction medium; the reaction medium can be carbon dioxide, and the carbon dioxide in the reaction hopper 102 is in a supercritical state. The depressurization transition hopper 103 is used to receive the reaction product from the reaction hopper 102 when its internal pressure reaches and is maintained at a target pressure. The discharge hopper 105 is used to collect the reaction product discharged from the depressurization transition hopper. It is understood that the feed hopper 104 and the discharge hopper 105 are atmospheric pressure vessels.
[0023] Furthermore, a first switching device is installed between the feed hopper 104 and the corresponding pressurized transition hopper 101; a second switching device is installed between the pressurized transition hopper 101 and the reaction hopper 102; a third switching device is installed between the reaction hopper 102 and the depressurization transition hopper 103; a fourth switching device is installed between the depressurization transition hopper 103 and the corresponding discharge hopper 105; and a fifth switching device is installed at the discharge port of the discharge hopper 105. The default state of each switching device is closed. The opening and closing actions of each switching device determine the transfer of materials between adjacent hoppers.
[0024] The control system is configured to: control the first fluid system 12 to continuously supply the reaction medium into the reaction chamber 102 and maintain the temperature and pressure within the reaction chamber 102 to meet preset temperature and pressure requirements (i.e., the temperature meets the preset temperature requirement, and the pressure meets the preset pressure requirement); and control the second fluid system 13 to supply high-pressure fluid into the pressurization transition chamber 101 and the depressurization transition chamber 103 to achieve pressurization within them.
[0025] The embodiments of the present invention adopt the above-mentioned technical solution. By setting up a pressurization transition chamber and a depressurization transition chamber, the solid material can be continuously fed and discharged intermittently while maintaining the high temperature and high pressure reaction conditions in the reaction chamber without interruption. This avoids repeated pressurization and depressurization operations in the reaction chamber, thereby greatly improving the overall production efficiency. Furthermore, since the reaction chamber does not need to be repeatedly depressurized and pressurized, the huge heat loss and compression power consumption caused by this are avoided, enabling the present invention to reduce production energy consumption.
[0026] In this embodiment of the invention, the number of the feeding hopper 104, the pressurizing transition hopper 101, the depressurizing transition hopper 103, and the discharging hopper 105 is at least one. Figure 1 (The example given is a quantity of 2).
[0027] The number of feed hoppers 104 and pressurized transition hoppers 101 are equal, and they are connected in a one-to-one correspondence.
[0028] The number of pressure relief transition chambers 103 and discharge chambers 105 are equal, and they are connected in a one-to-one correspondence.
[0029] In this embodiment of the invention, the first switching device, the second switching device, the third switching device, the fourth switching device, and the fifth switching device can all be electric switching devices.
[0030] The control system can also be configured as follows: (1) When it is determined that the solid material in the target feed hopper needs to be reacted, the corresponding first switch device is opened so that the solid material in the target feed hopper flows into the corresponding pressurized transition hopper.
[0031] Specifically, when it is determined that a reaction needs to be carried out on the solid material in the target feed hopper, the amount of solid material in the target feed hopper is pre-measured. That is, the amount of solid material flowing into the corresponding pressurized transition hopper is pre-measured.
[0032] The control system can determine whether a reaction is needed on the solid material in the target feed hopper based on relevant instructions sent by the user, or it can use other methods to determine whether a reaction is needed on the solid material in the target feed hopper.
[0033] (2) After confirming that all solid material in the target feed hopper has flowed into the corresponding pressurized transition hopper, the corresponding first switch device is closed, creating a sealed space for pressurization within the corresponding pressurized transition hopper. Simultaneously, the corresponding depressurization transition hopper also becomes a sealed space for pressurization. Then, the second fluid system is controlled to supply high-pressure fluid (i.e., reaction medium fluid) to both the corresponding pressurized and depressurized transition hoppers, so that the internal pressures of both hoppers reach and maintain the target pressure.
[0034] Specifically, a first pressure sensor can be installed in both the pressurization transition chamber and the depressurization transition chamber. The first pressure sensor is connected to the control system to detect the pressure data in the corresponding chamber in real time and send this pressure data to the control system. The control system determines the pressure in the corresponding chamber based on this pressure data, and closes the relevant pipeline valves in the second fluid system when the pressure reaches the target pressure. In this way, the internal pressure of the corresponding pressurization transition chamber and the corresponding depressurization transition chamber reaches and maintains the target pressure.
[0035] (3) When it is determined that the internal pressure of the corresponding pressurized transition chamber and the corresponding depressurized transition chamber has reached and maintained the target pressure, and there is no reaction in the reaction chamber, the corresponding second switch device is opened so that the solid material in the corresponding pressurized transition chamber flows into the reaction chamber.
[0036] It should be noted that throughout the entire production process, the control system controls the first fluid system 13 to run continuously in order to maintain a constant reaction environment in the reaction chamber 102 where the temperature and pressure meet the preset temperature and pressure requirements.
[0037] A second pressure sensor can be installed inside the reaction chamber. This second pressure sensor is used to detect the pressure data inside the reaction chamber in real time and send this pressure data to the control system. The control system controls the operating parameters of the first fluid system 13 based on this pressure data to maintain the pressure inside the reaction chamber 102 at the preset pressure requirement.
[0038] (4) After confirming that all solid materials in the pressurized transition chamber have flowed into the reaction chamber, control the corresponding second switch device to close.
[0039] (5) After the reaction in the reaction chamber is completed, control the corresponding third switch device to open so that the reaction material in the reaction chamber flows into the corresponding depressurization transition chamber.
[0040] Specifically, the control system can determine whether the reaction in the reaction chamber is complete based on the reaction time. For example, it can determine that the reaction in the reaction chamber is complete after the reaction time reaches 30 minutes.
[0041] (6) After determining that all the reaction material in the reaction chamber has flowed into the corresponding depressurization transition chamber, control the corresponding third switch to close and control the corresponding fourth switch to open so that the reaction material in the depressurization transition chamber flows into the corresponding discharge chamber.
[0042] (7) After determining that all the reaction material in the depressurization transition chamber has flowed into the corresponding discharge chamber, control the corresponding fourth switch to close and control the corresponding fifth switch to open, so that the reaction material in the discharge chamber flows into the preset material collection device.
[0043] (8) After determining that all the reaction material in the discharge hopper has flowed into the preset material collection device, control the corresponding fifth switch device to close.
[0044] It is understandable that during the execution of steps (5) to (8) above, a new batch of materials can simultaneously complete steps (1) and (2). Once the reaction chamber is emptied of the previous batch of products and the corresponding third switch device is closed, steps (3) to (8) can be executed again. This achieves seamless intermittent continuous production. The entire cycle repeats itself, ensuring that the core reaction chamber is always in optimal working condition, greatly improving production efficiency and energy utilization.
[0045] Furthermore, in this embodiment of the invention, the first switch device, the second switch device, the third switch device, the fourth switch device, and the fifth switch device may all be manual switch devices.
[0046] In this embodiment of the invention, the first fluid system may include a first pressurization device, a heating device, and a temperature sensor.
[0047] The first pressurizing device is used to pressurize the reaction medium fluid from the cooling device so that the pressure of the reaction medium fluid meets the preset pressure requirements.
[0048] The heating device is used to heat the pressurized reaction medium fluid.
[0049] A temperature sensor detects the temperature of the heated reaction medium fluid and sends this data to the control system. The control system then uses this temperature data to adjust the parameters of the heating device, causing the reaction medium fluid to transition to a supercritical state. Specifically, the control system can use a PID control algorithm to control the parameters of the heating device.
[0050] The heating device can be electric heating or hot water heating, etc. Its function is to heat the high-pressure liquid reaction medium to exceed its critical point. For example, when the reaction medium is carbon dioxide, the carbon dioxide is heated to exceed its critical point (31.1℃, 7.38 MPa) to transform it into supercritical carbon dioxide fluid.
[0051] The supercritical reaction medium, which meets the preset pressure requirements, flows into the reaction chamber under the drive of the first pressurization device, so that the temperature and pressure in the reaction chamber meet the preset temperature and pressure requirements.
[0052] In this embodiment of the invention, the first pressurization device includes a first pressurization pump and a pressurization tank.
[0053] The first booster pump is used to pressurize the reaction medium fluid from the cooling unit.
[0054] The pressurized reaction medium is temporarily stored in the pressurized fluid to replenish it in the reaction chamber as needed, ensuring that the temperature and pressure within the chamber consistently meet the preset requirements. It should be noted that the reaction medium in the pressurized tank flows into the reaction chamber after passing through a heating device.
[0055] In this embodiment of the invention, the second fluid system includes a second booster pump.
[0056] The second booster pump is used to pressurize the reaction medium fluid from the cooling device so that the pressure of the reaction medium fluid meets the preset pressure requirements.
[0057] The reaction medium fluid that meets the preset pressure requirements flows into the pressurization transition chamber and the depressurization transition chamber under the drive of the second booster pump, so that the internal pressure of the pressurization transition chamber and the depressurization transition chamber reaches and maintains the target pressure.
[0058] In this embodiment of the invention, the supercritical carbonization production equipment for solid materials may further include a cooling device 14.
[0059] The cooling device is used to cool the reaction medium flowing out of the reaction medium storage device to ensure that the reaction medium is in a fluid state when it enters the first fluid system or the second fluid system.
[0060] In a specific example, the cooling device 14 may include an evaporator, a refrigerator, and a condenser. The condenser cools the reaction medium flowing out of the reaction medium storage device to ensure that the reaction medium is in a fluid state when it enters the first or second fluid system. The refrigerator and evaporator work together to maintain a low temperature in the condenser.
