Description

Technical Field

[0001] The present invention relates to the technical field of carbonization reaction devices, and in particular to a gas distribution system for carbonization equipment. Background Art

[0002] Carbonized cementitious materials, rich in calcium silicate, magnesium silicate, calcium hydroxide, and magnesium hydroxide, can form high-strength carbonized products under carbon dioxide curing. This technology is energy-efficient and environmentally friendly. Carbonized cementitious materials, rich in calcium silicate and magnesium, are often sourced from industrial solid waste, including steel slag, magnesium slag, furnace slag, carbide slag, fly ash, and construction waste. This technology also saves energy and reduces emissions. During the curing process, each ton of carbonized cementitious materials absorbs 0.1 to 0.2 tons of carbon dioxide.

[0003] The specific mechanism of the reaction between steel slag and carbon dioxide is as follows: first, the water molecules in the product diffuse in the capillary pores of the steel slag preform; then the carbon dioxide diffuses and calcium ions precipitate, the carbon dioxide reacts with water to form carbonic acid, and then ionizes into carbonate ions; the carbonate ions and calcium ions combine to form calcium carbonate, thus forming a high-strength carbonized product.

[0004] It can be seen that the more calcium carbonate is produced, the stronger the product. However, in traditional carbonization curing equipment, the air inlets are often located at both ends and in the middle of the device. Moreover, to achieve industrial production of carbonized products, the width of the carbonization equipment is designed to be too long, resulting in uneven distribution of carbon dioxide gas within the equipment. Carbonized products have different degrees and depths of carbonization, which reduces the product qualification rate.

[0005] Therefore, how to make the gas distribution system of the carbonization equipment distribute gas evenly and stably to improve the qualified rate of the product is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0051] The core of the present invention is to provide a gas distribution system for carbonization equipment, so as to make the gas distribution uniform and stable, thereby improving the qualified rate of products.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] like Figure 1 As shown (the specific schematic diagram takes a vertical carbonization reaction tank as an example), an embodiment of the present invention discloses a gas distribution system for a carbonization device, including a carbonization device 100 and a carbon source separator 300.

[0054] Among them, the carbonization equipment 100 is used to carbonize the carbonization preform 600. It should be noted that the carbonization preform 600 refers to the material that needs to be carbonized. The carbonization equipment 100 has a hollow cavity. Specifically, the carbonization equipment 100 can be a carbonization reaction tank, a carbonization reaction box, a carbonization reaction kettle, a carbonization reactor or a carbonization reaction chamber 700, etc. The specific type is not limited here. A gas pipeline 200 is provided in the hollow cavity, and a plurality of gas outlets are provided on the gas pipeline 200, and the gas outlets are small gas outlets. The carbonization equipment 100 has an air inlet 110 and an exhaust port 120. The air inlet 110 is connected to the gas cylinder containing carbon dioxide, and the gas pipeline 200 is used to transport gas containing carbon dioxide. The gas will be pretreated before entering the gas pipeline 200, mainly including parameters such as gas temperature, humidity and pressure. Specifically, the gas pipeline 200 can be a gas hose. The gas pipeline 200 can be set on the side wall of the carbonization equipment 100, or on the bottom of the carbonization equipment 100, or on the top or inside the hollow cavity of the carbonization equipment 100. The specific setting position is not limited, and those skilled in the art can set it according to actual conditions.

[0055] The carbon source separator 300 is disposed within the hollow cavity of the carbonization apparatus 100. A plurality of gas outlet holes 310 are evenly distributed on the carbon source separator 300. Specifically, the gas outlet holes 310 provided on the carbon source separator 300 can be circular, square, triangular, or the like. The specific shape is not limited and can be determined by those skilled in the art based on actual conditions.

[0056] like Figure 14 and Figure 15 As shown, the layout of the outlet holes 310 on the carbon source separator 300 can be a circular layout or a square layout, which is not limited here and can be specifically configured by those skilled in the art according to actual circumstances. The sizes of the multiple outlet holes 310 can be set to the same size or a combination of holes of different sizes. The aperture size of the outlet holes 310 can be specifically set according to the type of carbonized preform 600. In a specific embodiment of the present invention, the aperture size of the outlet holes 310 can be set to a width of 0.5 cm-10 cm.

[0057] On the gas distribution path from the gas inlet 110 to the gas outlet 120 , the gas delivery pipeline 200 is located upstream of the carbon source separator 300 , and the carbonized preform 600 is located downstream of the carbon source separator 300 . When the carbonization preform 600 is to be carbonized, the carbonization preform 600 is placed inside the hollow cavity of the carbonization apparatus 100. The exhaust port 120 is closed, the air inlet 110 is connected to a gas cylinder containing carbon dioxide, and carbon dioxide gas is introduced into the carbonization apparatus 100. The exhaust port 120 is opened to exhaust the air in the carbonization apparatus 100. After the air is exhausted, the exhaust port 120 is closed. The carbon dioxide gas is transported to the interior of the carbonization apparatus 100 through the gas pipeline 200, flows out through the small gas outlet provided on the gas pipeline 200, then flows out through the carbon source separator 300 and out through the multiple gas outlet holes 310 uniformly provided on the carbon source separator 300, and carbonization and curing of the carbonization preform 600 is performed. After the carbonization and curing is completed, the exhaust port 120 is opened to exhaust the carbon dioxide gas, and the carbonized product is removed. The carbon dioxide gas flows out through the multiple gas outlet holes 310 provided on the carbon source separator 300, so that the gas is evenly distributed.

[0058] The gas distribution system for carbonization equipment provided by the present invention includes a carbonization device 100 and a carbon source separator 300. The carbonization device 100 is used to carbonize a carbonization preform 600. The carbonization device 100 has a hollow cavity, and a gas pipeline 200 is provided in the hollow cavity. The gas pipeline 200 is used to transport a gas containing carbon dioxide, and a plurality of small gas outlets are provided on the gas pipeline 200. The carbonization device 100 has an air inlet 110 and an exhaust port 120. The air inlet 110 is connected to the gas pipeline 200, and the exhaust port 120 is connected to the hollow cavity. The carbon source separator 300 is provided in the hollow cavity, and a plurality of gas outlet holes 310 are evenly provided on the carbon source separator 300. On the gas distribution path from the air inlet 110 to the exhaust port 120, the gas pipeline 200 is located upstream of the carbon source separator 300, and the carbonization preform 600 is located downstream of the carbon source separator 300. When carbon dioxide-containing gas is introduced, it enters the carbonization apparatus 100 through the gas pipeline 200, flows through the gas outlet on the gas pipeline 200, and then flows out through the multiple gas outlet holes 310 uniformly arranged on the carbon source separator 300, carbonizing the carbonized preform 600. The provision of multiple gas outlet holes 310 ensures uniform and stable airflow distribution, which helps improve the carbonization effect of the carbonized product and increases the product qualification rate.

[0059] like Figure 5As shown, the gas distribution system for carbonization equipment disclosed in an embodiment of the present invention has a variety of specific settings for the carbon source partition 300 and the gas pipeline 200. Specifically, the gas pipeline 200 can be set on one side of the carbon source partition 300, and the carbonized preform 600 is set on the other side of the carbon source partition 300. The carbon dioxide gas is transported to the interior of the carbonization equipment 100 through the gas pipeline 200, and is blown toward the carbonized preform 600 through a plurality of gas outlets 310 set on the carbon source partition 300.

[0060] like Figure 10 As shown, in a specific embodiment of the present invention, the carbon source separator 300 forms a separator cavity with an internal accommodation space, the gas pipeline 200 is arranged inside the separator cavity, and the carbonization preform 600 is arranged outside the separator cavity. The carbon dioxide-containing gas is transported to the carbonization equipment 100 through the gas pipeline 200, and then flows out through the multiple gas outlets 310 evenly arranged on the carbon source separator 300 wrapped around the outside of the gas pipeline 200, carbonizing the carbonization preform 600. Alternatively, as Figure 1 As shown, the carbon source separator 300 forms a separator cavity with an internal accommodation space, the gas pipeline 200 is disposed outside the separator cavity, and the carbonization preform 600 is disposed inside the separator cavity. Gas containing carbon dioxide flows through the gas pipeline 200 into the accommodation space enclosed within the carbon source separator 300 to carbonize and cure the carbonization preform 600. It will be appreciated by those skilled in the art that the specific configuration can be determined based on actual conditions.

[0061] like Figure 8 and Figure 9 As shown, in order to make the gas outflow more uniform, in a specific embodiment of the present invention, the carbon source separator 300 is surrounded by a separator cavity with an internal accommodation space, and one of the gas pipeline 200 and the carbonized preform 600 is arranged inside the separator cavity, and the other of the gas pipeline 200 and the carbonized preform 600 is arranged outside the separator cavity; the carbon source separator 300 is rotatably arranged in the hollow cavity. Specifically, two carbon source separators 300 can be spliced ​​together to form a cylindrical hollow cavity, and the carbon source separator 300 can be driven to rotate by a driving motor or other driving equipment. The carbon source separator 300 can rotate in the horizontal direction or in the vertical direction, depending on the specific situation. When the carbonized preform 600 moves forward in the carbonization equipment 100, a carbon source separator 300 rotating in the horizontal direction can be used, and the carbonization effect is better at this time; when the carbonized preform 600 is arranged at a higher height in the carbonization equipment 100, a carbon source separator 300 rotating in the vertical direction can be used, and the carbonization effect is better at this time.

[0062] like Figure 11As shown, to achieve uniform gas distribution, in one embodiment of the present invention, a fan 320 is provided on the gas outlet 310. When the fan 320 rotates, it pushes the carbon dioxide-containing gas toward the carbonized preform 600, thereby creating a negative pressure in that area. The pressure in the area between the carbon source separator 300 and the gas pipeline 200 continues to increase, causing the pressure in the gas pipeline 200 area to be greater than the pressure in the carbonized preform 600 area. The carbon dioxide-containing gas flows from the high-pressure area to the low-pressure area. The continuous rotation of the fan 320 blades continuously draws the carbon dioxide-containing gas inward, thereby achieving uniform gas distribution.

[0063] like Figure 12 As shown, to facilitate the control of the opening and closing of the gas outlets 310 at different locations, in a specific embodiment of the present invention, the carbon source separator 300 includes a plurality of detachable carbon source separator pore strips 330. Specifically, the carbon source separator pore strips 330 can be connected to the carbon source separator 300 by plugging and unplugging. When a carbonization preform 600 at the same height needs to be carbonized, the corresponding carbon source separator pore strip 330 can be installed on the carbon source separator 300. When there is no carbonization preform 600 at the corresponding height, the carbon source separator pore strip 330 at the corresponding height can be removed. If the spacing between the placement heights of the carbonization preform 600 and the spacing between the carbon source separator pore strips 330 are different, the distance between the corresponding carbon source separator pore strips 330 can also be adjusted to ensure that the gas outlets 310 correspond to the placement heights of the carbonization preform 600, shortening the distance between the carbonization gas and the carbonization preform 600, and ensuring a more uniform distribution of the carbon dioxide-containing gas within the carbonization apparatus 100. During the maintenance of carbonized products, the carbonization degree and depth of the carbonized products are greatly improved, and the product qualification rate and mechanical properties are also significantly improved. The carbon source separator pore strips 330 in the figure can be removed horizontally. Those skilled in the art will understand that the carbon source separator pore strips 330 can also be removed vertically, depending on the specific situation.

[0064] like Figure 13 As shown, to facilitate control over the opening and closing of the gas outlet 310, in one embodiment of the present invention, a movable shielding plate 340 is provided on the gas outlet 310 to control the opening and closing of the gas outlet 310. When the gas outlet 310 disposed at a certain height on the carbon source separator 300 corresponds to the absence of the carbonized preform 600 or the carbonization reaction is complete, the gas outlet 310 can be closed by moving the shielding plate 340 downward. The shielding plate 340 shown in the figure can move vertically, but those skilled in the art will appreciate that the shielding plate 340 can also be configured to move horizontally.

[0065] In a specific embodiment of the present invention, the carbonization equipment 100 includes an equipment chamber 130 and an equipment chamber door 140. The specific type of the carbonization equipment 100 can be a carbonization reaction tank, a carbonization reaction kettle, or a carbonization reactor. Figure 1 The carbonization reaction tank is used as an example for explanation. Specifically, the equipment chamber 130 has a cylindrical hollow cavity. Figure 1 The carbonization reaction tank is open on one side, meaning only one side is open, with an equipment door 140, and the bottom is sealed. The air inlet 110 and exhaust port 120 are respectively provided on the equipment door 140, which is also equipped with a monitoring instrument 150. Specifically, the number of air inlets 110 can be set to two. Those skilled in the art will appreciate that the number of air inlets 110 is not limited to two and can be set according to actual circumstances.

[0066] like Figure 1 and Figure 2 As shown, the air inlet 110 is connected to the gas pipeline 200, which is arranged on the side wall of the equipment room 130. Specifically, the gas pipeline 200 includes a first gas pipeline 210 and a second gas pipeline 220. One of the air inlets 110 is connected to the first gas pipeline 210. The first gas pipeline 210 extends vertically downward to the bottom of the equipment room 130, then horizontally to the right to the right side wall of the right equipment room 130, and then upward to be fixed at the opening of the equipment room 130. The other air inlet 110 is connected to the second gas pipeline 220. The second gas pipeline 220 extends to the bottom of the equipment room 130, then to the front side wall of the equipment room 130, and then extends upward out of the equipment room 130. The first gas pipeline 210 and the second gas pipeline 220 are arranged vertically. Those skilled in the art will understand that the figure only shows one embodiment of the specific distribution of the gas pipeline 200. There are many ways to arrange the gas pipeline 200 in the equipment room 130. The gas pipeline 200 can be arranged at any angle of the equipment room 130. The gas pipeline 200 can be distributed in a spiral downward from the air inlet 110, or spiral upward from the bottom of the equipment room 130. The specific arrangement can be selected according to the location and type of the carbonized preform 600.

[0067] like Figure 1 and Figure 3 As shown, a carbon source separator 300 is positioned between the gas pipeline 200 and the hollow cavity. The separator 300 forms a chamber with a storage space within, and the carbonized preform 600 is placed within the chamber. Specifically, the separator 300 is arranged in a rectangular configuration and is provided with evenly spaced gas outlet holes 310. The left and right sides of the separator 300 are connected to form a cylindrical, enclosed chamber, and the carbonized preform 600 is placed within the chamber.

[0068] When carbonizing the carbonization preform 600, the pressed carbonization preform 600 is placed in the partition cavity, and the equipment chamber door 140 is buckled on the equipment chamber 130. In order to ensure the good airtightness of the carbonization equipment 100, a fastener 400 is provided between the equipment chamber door 140 and the equipment chamber 130. After the equipment chamber door 140 is buckled on the equipment chamber 130, the carbonization equipment 100 maintains good sealing through the fastener 400. Specifically, the fastener 400 can be a fastening nut. Close the exhaust port 120, connect the air inlet 110 and the gas cylinder containing carbon dioxide, introduce carbon dioxide-containing gas into the carbonization equipment 100, adjust the pressure to a suitable level through the indication of the monitoring instrument 150, open the exhaust port 120, exhaust the air in the carbonization equipment 100, and after the air is exhausted, close the exhaust port 120 and start carbonization maintenance of the carbonization preform 600. After the curing is completed, the exhaust port 120 is opened to exhaust the gas, the fastener 400 is loosened, the carbonization device 100 is opened, the carbonized product is taken out, and the water generated by the reaction in the carbonization device 100 is cleaned.

[0069] like Figure 4 As shown, based on the above embodiment, a carbonized preform 600 is placed on a product carbonization rack 500, which is located within the partition cavity. A breathable filter is installed around the inner walls and bottom of the product carbonization rack 500. Specifically, the product carbonization rack 500 can be cylindrical or cubic in shape. To facilitate the entry of carbon dioxide-containing gas, a breathable filter is installed around the inner walls and bottom of the product carbonization rack 500. The carbonized preform 600 can be placed on the bottom filter.

[0070] In order to carbonize multiple carbonization preforms 600 simultaneously, multiple product carbonization racks 500 can be stacked together. The figure shows three product carbonization racks 500 stacked together. The bottom metal frame of the product carbonization rack 500 extends downward a certain distance to maintain a certain distance between each product carbonization rack 500. The carbonized products placed on each layer as shown in the figure are carbonized bricks or plates, carbonized blocks, carbonized columns, and carbonized aggregates. The filter screen on the side wall of the product carbonization rack 500 and the air outlet 310 in the carbon source partition 300 are kept at the same height in the horizontal position, so that the carbonized gas flows out of the air outlet 310 and directly enters the interior of the product carbonization rack 500, thereby achieving a better carbonization effect. It should be noted that if the carbonization equipment 100 is a carbonization reaction box with a single-side opening, the same layout as the carbonization reaction tank can be adopted.

[0071] like Figure 5-Figure 7As shown, in a specific embodiment of the present invention, the carbonization equipment 100 is a carbonization reaction chamber 700. The gas pipeline 200 is disposed on the side wall of the carbonization reaction chamber 700, and the gas pipeline 200 is disposed on one side of the carbon source separator 300. The carbonization reaction chamber 700 is provided with a transport track 720, and the transport track 720 is disposed on the other side of the carbon source separator 300. Specifically, the transport track 720 is disposed at the bottom of the carbonization reaction chamber 700. The carbonized preform 600 is placed on the carbonized product transport equipment and enters the carbonization reaction chamber 700 through the transport track 720. Specifically, the carbonization reaction chamber 700 is provided with a chamber door 710 at both the front and rear of the carbonization reaction chamber 700. The chamber door 710 is used to control the opening and closing of the carbonization reaction chamber 700. The gas pipeline 200 can be disposed on the side wall of the carbonization reaction chamber 700 or on the top of the carbonization reaction chamber 700. The specific location is not limited here. Figure 5 The gas pipeline 200 is provided on the side wall of the carbonization reaction chamber 700. The gas pipeline 200 can be provided on only one side wall of the carbonization reaction chamber 700, or on two opposite side walls (e.g., Figure 6 As shown), at this time, the transport track 720 laid at the bottom of the carbonization reaction chamber 700 is set in the middle position of the carbonization reaction chamber 700, and the gas pipelines 200 on both sides can carbonize the carbonized preform 600 through the carbon source partition 300.

[0072] Specifically, the gas pipeline 200 is provided with a number of gas outlets. A carbon source separator 300 is located on one side of the gas pipeline 200. Gas outlet holes 310 are evenly distributed on the carbon source separator 300. The gas outlet holes 310 shown in the figure are circular in shape. A transport track 720 is laid at the bottom of the carbonization reaction chamber 700. The transport track 720 is arranged on the other side of the carbon source separator 300 opposite the gas pipeline 200. Carbonized product transport equipment can be placed on the transport track 720. A carbonization rack 800 is placed on the carbonized product transport equipment. Multiple carbonization racks 800 can be stacked and placed on the carbonized product transport equipment. To ensure that each carbonization rack 800 has a flow of carbon dioxide-containing gas, pillars are provided on the carbonization racks 800 as partitions.

[0073] It should be noted that the carbonization reaction chamber 700 can be used in two modes: dynamic use and static use. During static use, after the carbonized preform 600 is placed on the carbonization rack 800, the cart is pushed into the carbonization reaction chamber 700, the front and rear doors 710 of the carbonization reaction chamber 700 are closed, and carbonization is carried out by introducing gas containing carbon dioxide. During dynamic use, the doors 710 of the carbonization reaction chamber 700 at both ends are kept open, and the operating speed of the carbonization product transport equipment is set according to the required carbonization time and the length of the carbonization reaction chamber 700. When the carbonization product transport equipment slowly passes through the air outlet 310, carbonization occurs while the carbonization product is moving. After carbonization is completed, the product is pushed out from the door 710 of the carbonization reaction chamber 700 at the rear end. It will be understood by those skilled in the art that when the carbonization equipment 100 is a tunnel-type carbonization reactor with openings on both sides, the same arrangement can also be used.

[0074] like Figure 10 As shown in the figure, it is a schematic structural diagram of a revolving lantern-style carbon source partition 300. The gas pipeline 200 is arranged inside the cavity of the carbonization reaction chamber 700. The carbon source partitions 300 are connected end to end to form a partition cavity with a accommodating space. The gas pipeline 200 is located inside the partition cavity, and the air outlet holes 310 are evenly distributed on the carbon source partition 300. A plurality of carbon source partitions 300 are arranged at intervals in the middle position of the carbonization reaction chamber 700. Transport tracks 720 are respectively provided on both sides of the carbon source partition 300, and the carbon source partition 300 can rotate in the horizontal direction. When in use, after the carbonization rack 800 is placed on the transport track 720, the carbon dioxide gas flows out through the air outlet 310. As the carbon source partition 300 rotates, the carbon dioxide gas gushes to the surroundings, thereby making the gas distribution effect more uniform.

[0075] To extend the service life of the carbonization apparatus 100, the gas distribution system for carbonization equipment disclosed in the embodiment of the present invention is provided with an anti-corrosion coating and / or a waterproof coating on the inner wall of the carbonization apparatus 100. Furthermore, the gas distribution system for carbonization equipment disclosed in the embodiment of the present invention also includes a control module for setting and monitoring carbonization conditions and adjusting carbonization parameters in a timely manner.
