Abstract

The invention discloses a mineralization kettle external circulation distribution pipeline which comprises a main air inlet pipeline connected with an air inlet of a pressure-bearing fan and a main air outlet pipeline connected with an air outlet of the pressure-bearing fan, first-stage balance branch pipes are connected to the lower portion of the main air inlet pipeline or the main air outlet pipeline, and second-stage balance branch pipes are connected to the two ends of each first-stage balance branch pipe. The two ends of the second-stage balance branch pipe are connected with third-stage balance branch pipes, and the third-stage balance branch pipes are connected to a carbon dioxide diffuser in the mineralization kettle. The carbon dioxide diffusers are arranged in the mineralization kettle, so that the pressure, the flow speed and the flow of carbon dioxide in the multiple carbon dioxide diffusers in the mineralization kettle are equal, and the carbon dioxide uniformly circulates on the surface of the mineral substance at a certain speed in a turbulent flow manner. By arranging the main pipeline, the balance branch pipe and the carbon dioxide diffuser, uniform circulating flow of carbon dioxide in the mineralization kettle is realized, and rapid mass transfer homogenization of mineralization reaction is realized.

Description

Technical Field

[0001] This invention belongs to the field of carbon dioxide circulation technology for mineralization reactors, and particularly relates to an external circulation distribution pipeline for mineralization reactors. Background Technology

[0002] Mineralization requires carbon dioxide to react with minerals at a temperature of 120℃ and a pressure of 1.2 MPa. Carbon dioxide forms homogenized turbulence at the mass transfer surface to improve the mass transfer rate and promote the mineralization reaction. This necessitates that the carbon dioxide circulates uniformly and turbulently at a certain velocity on the mineral surface at 120℃ and 1.2 MPa. However, traditional mineralization reactors have the following shortcomings: 1. Carbon dioxide circulation requires a blower, but a blower cannot be installed inside a double-door mineralization reactor; 2. High-flow centrifugal fans cannot withstand pressure of 1.2 MPa; 3. Carbon dioxide circulates uniformly in a turbulent flow at a certain speed on the surface of minerals, but there is no suitable flow guiding device. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this invention proposes an external circulation distribution pipeline for a mineralization reactor. A pressure fan is installed outside the mineralization reactor to achieve carbon dioxide circulation, realizing a 1.2MPa carbon dioxide external circulation of the mineralization reactor. The circulation of carbon dioxide is achieved by setting up a main pipeline and branch pipes, resulting in uniform circulation flow.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An external circulation distribution pipeline for a mineralization reactor includes a main inlet pipe connected to the air inlet of a pressure blower and a main outlet pipe connected to the air outlet of the pressure blower. The two ends of the main inlet pipe and the main outlet pipe are connected to the mineralization reactor through several balanced branch pipes.

[0005] Furthermore, each of the main air inlet pipe or main air outlet pipe is connected to a primary balancing branch pipe, both ends of the primary balancing branch pipe are connected to secondary balancing branch pipes, both ends of the secondary balancing branch pipes are connected to tertiary balancing branch pipes, and the tertiary balancing branch pipes are connected to the mineralization reactor.

[0006] Furthermore, a carbon dioxide diffuser is installed inside the mineralization reactor, and the three-stage balance branch pipe is connected to the mineralization reactor through the carbon dioxide diffuser.

[0007] Furthermore, the pressure fan is located at the top of the mineralization reactor.

[0008] Furthermore, the three-stage balancing branch pipes connected to the main air inlet pipe and the three-stage balancing branch pipes connected to the main air outlet pipe are arranged in a one-to-one correspondence on both sides of the mineralization reactor.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. An external carbon dioxide circulation system is used, with the pressure fan located outside the mineralization reactor to achieve carbon dioxide circulation; the circulation and uniform flow of carbon dioxide are achieved through main and branch pipes. 2. Since the high-flow centrifugal fan cannot withstand the pressure of 1.2MPa, the centrifugal fan is placed in a container with the same pressure as carbon dioxide, so that the ambient pressure of the centrifugal fan is equal to that of carbon dioxide, thus realizing the external circulation of 1.2MPa carbon dioxide in the mineralization reactor. 3. The end of the balancing branch pipe is connected to a carbon dioxide diffuser installed inside the mineralization reactor. This ensures that the carbon dioxide pressure, flow rate, and flow rate of the multiple carbon dioxide diffusers within the mineralization reactor are equal, achieving a uniform turbulent circulation of carbon dioxide on the mineral surface at a certain speed. By setting up the main pipe, balancing branch pipe, and carbon dioxide diffuser, uniform circulation of carbon dioxide within the mineralization reactor is achieved, enabling rapid and homogenized mass transfer in the mineralization reaction.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] This invention provides an external circulation distribution pipe for a mineralization reactor, such as... Figure 1 As shown, it includes a main air inlet pipe 1 connected to the air inlet of the pressure blower and a main air outlet pipe 2 connected to the air outlet of the pressure blower. The two ends of the main air inlet pipe 1 and the main air outlet pipe 2 are connected to the mineralization reactor 3 through several balanced branch pipes.

[0014] Furthermore, each of the main air inlet duct 1 or the main air outlet duct 2 is connected to a primary balancing branch pipe 11. Both ends of the primary balancing branch pipe 11 are connected to secondary balancing branch pipes 12, and both ends of the secondary balancing branch pipes 12 are connected to tertiary balancing branch pipes 13. The tertiary balancing branch pipes 13 are connected to the mineralization reactor 3. A carbon dioxide diffuser 14 is installed inside the mineralization reactor 3, and the tertiary balancing branch pipes 13 are connected to the carbon dioxide diffuser 14 to access the mineralization reactor 3. The pressure fan is located at the top of the mineralization reactor 3. The tertiary balancing branch pipes connected to the main air inlet duct 1 and the tertiary balancing branch pipes connected to the main air outlet duct are arranged in a one-to-one correspondence on both sides of the mineralization reactor 3.

[0015] Detailed implementation instructions: Because the pressure inside the mineralization reactor reaches 1.2 MPa, the blower also needs to withstand this pressure when circulating air is applied. Since a high-flow-rate centrifugal blower cannot withstand 1.2 MPa, the centrifugal blower is placed inside a container at the same pressure as the carbon dioxide, ensuring that the ambient pressure of the centrifugal blower is equal to that of the carbon dioxide, thus achieving external circulation of 1.2 MPa carbon dioxide from the mineralization reactor. The circulation and uniform flow of carbon dioxide are achieved through the installation of main and branch pipes.

[0016] The end of the balancing branch pipe is connected to a carbon dioxide diffuser installed inside the mineralization reactor. This ensures that the carbon dioxide pressure, flow rate, and flow rate are equal across multiple carbon dioxide diffusers within the reactor, achieving a uniform turbulent circulation of carbon dioxide on the mineral surface at a certain velocity. By configuring the main pipe, balancing branch pipe, and carbon dioxide diffuser, uniform circulation of carbon dioxide within the mineralization reactor is achieved, enabling rapid and homogenized mass transfer in the mineralization reaction.
