Description

Technical Field

[0001] The invention relates to the technical field of carbon sequestration, and in particular to a carbon sequestration reaction experimental device. Background Art

[0002] Carbon sequestration is a technology aimed at reducing the concentration of carbon dioxide in the atmosphere. It is increasingly used in energy and power production, industrial production, oil and gas extraction, and sustainable development. The carbon sequestration reaction experiment simulates the effect of the chemical reaction between underground rock and carbon dioxide on the concentration of carbon dioxide by injecting carbon dioxide into a container filled with limestone. When conducting a carbon sequestration reaction experiment, corresponding equipment is required for specific operations.

[0003] Existing carbon sequestration reaction experimental devices are usually composed of a carbon dioxide production and capture device, a carbon dioxide transportation device and a carbon dioxide sequestration device. During the experiment, the carbon dioxide required for the experiment is generated by the reaction of hydrochloric acid and calcium carbonate, and the carbon dioxide is transported to the storage site under the action of the transportation device. However, the existing devices usually do not have the function of stirring the hydrochloric acid and calcium carbonate when reacting. At this time, if the calcium carbonate particles are large or unevenly distributed, it will affect the reaction rate, and the calcium carbonate precipitate produced by the reaction is also easy to accumulate at the bottom of the reactor, which may also hinder the reaction. In addition, the transportation location of the carbon dioxide by the transportation device is fixed, and it is impossible to detect the carbon dioxide sequestration effect under dynamic conditions.

[0004] Therefore, it is necessary to design a carbon sequestration reaction experimental device. Summary of the invention

[0022] Reference Figure 1-Figure 11 A carbon storage reaction experimental device includes a reaction tank 2 fixedly mounted on a storage box 1. The storage box 1 is used to store carbon dioxide, so it needs to be filled with some substances for storing carbon dioxide, such as limestone, coal seam, salt rock layer, etc. The reaction tank 2 is used for the reaction of dilute hydrochloric acid and calcium carbonate, and generally a glass container can be used. It also includes: The self-stirring part is used to automatically stir the reactants in the reaction tank 2. The self-stirring part includes a rotating rod 10 which is sealed and rotatably installed on the reaction tank 2, and a plurality of stirring blades 11 are fixedly installed on one end of the rotating rod 10 located in the reaction tank 2. When the rotating rod 10 rotates, the dilute hydrochloric acid and calcium carbonate located therein can be stirred by the rotation of the plurality of stirring blades 11 thereon in the reaction tank 2, so that the calcium carbonate is evenly distributed and fully mixed with the dilute hydrochloric acid, thereby ensuring the reaction rate. At the same time, the problem of calcium carbonate precipitate accumulating at the bottom of the reaction tank 2 to hinder the reaction can be avoided.

[0023] An addition port 3 is fixedly installed on the upper end of the reaction tank 2, and a sealing plug is threadedly connected to the addition port 3. The design of the addition port 3 is used to add the required dilute hydrochloric acid and calcium carbonate into the reaction tank 2 in corresponding proportions before the reaction.

[0024] A through slot is provided on the front side wall of the sealing box 1, and a sealing door 8 is hingedly connected to the through slot. A handle 9 is fixedly installed at the front end of the sealing door 8. Through the design of the sealing door 8, the corresponding sealing material can be filled in the sealing box 1 as needed.

[0025] A thread groove 12 is provided on the side wall of one end of the rotating rod 10 located outside the reaction tank 2, and a positioning block 14 is fixedly installed on the top of the rotating rod 10, a heat-conducting sleeve 17 is fixedly installed on the side wall of the reaction tank 2, and a fixing ring 16 is installed on the heat-conducting sleeve 17 through a pushing assembly, and a driving assembly is installed between the fixing ring 16 and the rotating rod 10, and the driving assembly includes a threaded sleeve 13 and two L-shaped rods 15, and the two L-shaped rods 15 are fixedly installed on the upper end of the fixing ring 16, the threaded sleeve 13 is fixedly installed between the two L-shaped rods 15, and the threaded sleeve 13 is threadedly connected with the thread groove 12, when the fixing ring 16 is relative to the reaction tank 2 When moving up and down, the design of the two L-shaped rods 15 thereon can drive the threaded sleeve 13 to move up and down at the same time. At this time, with the cooperation of the threaded sleeve 13 and the threaded groove 12, since the rotational connection between the rotating rod 10 and the reaction tank 2 limits the up and down position of the rotating rod 10, the movement of the threaded sleeve 13 can cause the rotating rod 10 to rotate through the threaded groove 12, thereby driving the stirring blade 11 to stir the reactants in the reaction tank 2. The design of the positioning block 14 can limit the moving distance of the threaded sleeve 13 relative to the rotating rod 10, ensuring that the threaded sleeve 13 and the threaded groove 12 are always in an effective threaded connection state.

[0026] The pushing assembly includes a piston ring 18 and a plurality of fixed rods 20. The piston ring 18 is sealingly and slidably installed in the heat-conducting sleeve 17. The plurality of fixed rods 20 are fixedly installed between the piston ring 18 and the fixed ring 16, and the plurality of fixed rods 20 are slidably matched with the heat-conducting sleeve 17. The heat-conducting sleeve 17 is filled with alcohol at the lower end of the piston ring 18. The alcohol here can also be replaced by other liquids with low boiling points. Since dilute hydrochloric acid and calcium carbonate are exothermic reactions, during the reaction process, the alcohol at the lower end of the heat-conducting sleeve 17 will be heated and quickly vaporized. At this time, the pressure in the space at the lower end of the piston ring 18 will change. Under the action of pressure, the piston ring 18 moves up in the heat-conducting sleeve 17, and the fixed ring 16 is pushed up by the fixed rod 20 to drive the rotation of the rotating rod 10. Since the drive is carried out by the heat released during the reaction process, there is no need for manual control, and no additional energy consumption. The degree of automation is high, and the alcohol vaporization absorbs heat, which can also reduce the overall temperature of the reaction tank 2 to avoid scalding of the staff.

[0027] A plurality of springs 19 are installed between the top of the piston ring 18 and the heat-conducting sleeve 17, and each spring 19 is respectively sleeved with the corresponding fixing rod 20. Under the elastic force of the spring 19, when the reaction is completed, the vaporized alcohol is liquefied again due to the reduction of heat. At this time, the elastic force of the spring 19 will apply a downward thrust to the piston ring 18, causing it to automatically move down and reset to prepare for subsequent reactions.

[0028] The input part is used to input carbon dioxide into the storage box 1. The input part includes an air duct 4 fixedly connected between the storage box 1 and the reaction tank 2. A flow meter 5 is fixedly installed on the air duct 4. The carbon dioxide generated in the reaction tank 2 will enter the storage box 1 through the air duct 4 and enter the sealed material therein. The flow meter 5 is used to detect the concentration of carbon dioxide entering the storage box 1 and record it.

[0029] The output detection unit is used to detect the carbon dioxide content discharged from the storage box 1. The output detection unit includes a discharge pipe 6 fixedly connected to the side wall of the storage box 1, and a flow meter 2 7 is fixedly installed on the discharge pipe 6. The end of the discharge pipe 6 connected to the storage box 1 is located above the bottom of the air guide pipe 4. The carbon dioxide entering the storage box 1 may still partially overflow after entering the sealed material. At this time, the overflowed carbon dioxide will be discharged through the discharge pipe 6. The carbon dioxide discharged through the discharge pipe 6 can be introduced into the corresponding reaction solution for reaction, thereby avoiding direct discharge into the atmosphere. The flow meter 2 7 can detect the concentration of carbon dioxide discharged from the discharge pipe 6. After that, the experimenter can obtain data on the carbon dioxide storage effect by comparing the data of the flow meter 1 5 and the flow meter 2 7.

[0030] Flow meter 1 5 and flow meter 2 7 are both existing products, so their working principles and specific structures are not elaborated in detail here.

[0031] One end of the air guide tube 4 located in the storage box 1 is sealed and slidably connected to the connecting tube 21, and two pulling components are installed between the connecting tube 21 and the fixed ring 16. The pulling components include a connecting rod 23 and a docking rod 24. The connecting rod 23 is fixedly installed on the upper end of the connecting tube 21, and the connecting rod 23 is slidably and sealingly connected to the storage box 1. The docking rod 24 is fixedly installed on the upper end of the fixed ring 16, and a socket mechanism is installed between the connecting rod 23 and the docking rod 24.

[0032] The socket mechanism includes a docking sleeve 25, which is slidably mounted on the connecting rod 23, and one end of the docking sleeve 25 close to the docking rod 24 is also slidably matched with the docking rod 24. When the docking sleeve 25 is connected to the connecting rod 23 and the docking rod 24 at the same time, the two can be connected as a whole. At this time, when the fixed ring 16 moves up, the connecting pipe 21 can be pulled up in the sealing box 1 through the cooperation of the connecting rod 23 and the docking rod 24, so that the depth of the input pipe 22 inserted into the sealed material can be adjusted. By continuously moving the position, the sealing effect of carbon dioxide under a dynamic input environment can be detected, thereby improving the comparison range of experimental data and improving the accuracy of experimental results.

[0033] A docking block 27 is fixedly installed in the docking sleeve 25, and a docking groove 26 is provided on the side wall at one end close to the connecting rod 23 and the docking rod 24, and the two docking grooves 26 are engaged with the docking block 27. The length of the docking sleeve 25 is greater than the distance between the connecting rod 23 and the docking rod 24, and the length of the docking block 27 is less than the distance between the connecting rod 23 and the docking rod 24. Through the cooperation between the docking block 27 and the docking groove 26, when the docking sleeve 25 is connected to the connecting rod 23 and the docking rod 24, the angle between the three can be guaranteed to be stable, thereby preventing the docking sleeve 25 from rotating or sliding and affecting the connection effect between the connecting rod 23 and the docking rod 24.

[0034] When there is no need to conduct a carbon dioxide sealing effect experiment in a dynamic environment, the docking sleeve 25 is moved to separate it from the docking rod 24. At this time, the movement of the fixing ring 16 cannot drive the connecting tube 21 to move in the sealing box 1, thereby ensuring that the position of the input tube 22 in the sealed material remains unchanged, and the sealing effect under static conditions is tested, which effectively increases the experimental detection range, and the switching operation between the two states is simple and will not increase the overall experimental difficulty.

[0035] In the present invention, the working principle of a carbon sequestration reaction experimental device includes the following steps: Generation of carbon dioxide: Add the reaction raw materials dilute hydrochloric acid and calcium carbonate into the reaction tank 2 in a certain proportion through the addition port 3, and then the two react chemically to generate carbon dioxide; Stirring during the reaction: Since the reaction of dilute hydrochloric acid and calcium carbonate to generate carbon dioxide is an exothermic reaction, the temperature increase of the reaction tank 2 will heat the heat-conducting sleeve 17. At this time, the alcohol in the heat-conducting sleeve 17 located at the lower end of the piston ring 18 will quickly depressurize to increase the pressure there; Under the action of air pressure, the piston ring 18 moves upward and drives the fixing ring 16 to move upward through the fixing rod 20, so that the rotating rod 10 rotates under the cooperation of the L-shaped rod 15 and the threaded sleeve 13, and then the multiple stirring blades 11 rotate in the reaction tank 2 to mix the dilute hydrochloric acid and calcium carbonate evenly, and avoid the accumulation of calcium carbonate precipitates at the bottom of the reaction tank 2, effectively ensuring the reaction rate; Input of carbon dioxide: The carbon dioxide generated in the reaction tank 2 will enter the sealed material inside the sealing box 1 through the air duct 4, and the sealed material will be used to seal the carbon dioxide; Dynamic sealing of carbon dioxide: ensure that both ends of the docking sleeve 25 are connected to the connecting rod 23 and the docking rod 24 respectively. At this time, due to the upward movement of the fixing ring 16, the connecting rod 23 and the docking rod 24 will pull the connecting pipe 21 to move upward in the sealing box 1, so the depth of the input pipe 22 in the sealed material will change dynamically, and the input depth of carbon dioxide in the sealed material will change at the same time, thereby completing the dynamic sealing of carbon dioxide; Static sealing of carbon dioxide: the docking sleeve 25 is moved to separate one end of it from the docking rod 24. At this time, the fixing ring 16 moves upward and cannot drive the connecting rod 23 to move through the docking rod 24. Therefore, the position of the connecting pipe 21 in the sealing box 1 remains unchanged, and the depth of the input pipe 22 in the sealed material does not change. At this time, the input depth of carbon dioxide in the sealed material also remains unchanged, thereby completing the static sealing of carbon dioxide; Detection of sealing effect: The concentration of carbon dioxide input into the sealing box 1 will be recorded when passing through flow meter 1 5. After sealing, some of the unsealed carbon dioxide will be discharged through the discharge pipe 6. At this time, flow meter 2 7 will record the concentration of the discharged carbon dioxide. The sealing effect of carbon dioxide can be obtained by comparing the two sets of data.

[0036] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
