Description

Technical Field

[0001] The utility model relates to the field of carbon dioxide collection, in particular to a collection device for capturing carbon dioxide. Background Art

[0002] Carbon dioxide is a carbon oxide with the chemical formula CO2. It is a colorless and odorless gas at room temperature and pressure. It is also a common greenhouse gas. With the substantial improvement in the living standards of our people, the demand for carbon dioxide in areas such as food preservation and beverages has also greatly increased.

[0003] The current carbon dioxide collection device collects carbon dioxide by capturing it from the air. After absorbing it for a period of time, the carbon dioxide content in the surrounding environment decreases. However, the collection device is still in a working state. At this time, the power consumption is the same, but the amount of carbon dioxide collected is reduced. Therefore, the carbon dioxide capture device needs to be improved to reduce unnecessary work. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a collection device for capturing carbon dioxide, so as to solve the technical problem of low efficiency of the carbon dioxide capture device after a long time.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a collection device for capturing carbon dioxide, comprising a device body, a liquid tank,

[0006] A front draft mechanism, the front draft mechanism comprising a shell, a vertically mounted draft fan is arranged inside the shell, the lower end of the draft fan is fixed to the inner wall of the shell through a mounting frame, a front filter is arranged above the draft fan, and an air intake pipe is installed on the top of the front draft mechanism through a flange;

[0007] A carbon dioxide monitor is installed on the air intake pipe, and the model of the carbon dioxide monitor is sk-600-CO2.

[0008] By adopting the above technical solution, the design of the pre-filter can effectively remove large particle impurities in the air, improve the air quality entering the device, and protect subsequent processing components from contamination and damage. The induced draft fan is installed vertically and firmly fixed to the inner wall of the shell through the mounting frame, ensuring the stable operation of the induced draft fan.

[0009] Furthermore, a collecting assembly is installed inside the main body of the device, and the collecting assembly includes two filter screens arranged in parallel up and down and a carbon dioxide adsorbent located between the two filter screens.

[0010] By adopting the above technical solution, the filter and the carbon dioxide adsorbent form a highly efficient adsorption and collection mechanism. The filter can initially filter out large particles of impurities in the air to ensure that the gas entering the adsorbent is purer, while the carbon dioxide adsorbent can selectively adsorb carbon dioxide molecules, thereby achieving effective collection of the target gas.

[0011] Furthermore, a first connecting pipe is installed on the top of the device body, the first connecting pipe is threadedly connected to the lower end of the front air induction mechanism, and a sealing ring is provided at the connection between the first connecting pipe and the front air induction mechanism.

[0012] By adopting the above technical solution and using a threaded connection method, the connection between the first connecting pipe and the front air induction mechanism is very convenient. When installation or disassembly is required, it can be completed by rotating the corresponding parts without using additional tools or complicated operating steps. This not only improves the efficiency of installation and disassembly, but also helps to reduce the risk of damage caused by improper operation.

[0013] Furthermore, the interior of the liquid tank is injected with chemical absorption liquid, an air outlet pipe is provided on the upper side of one side of the liquid tank, an aeration pipe is installed on the lower part of the interior of the liquid tank, and the aeration pipe is a curved structure.

[0014] By adopting the above technical solution, the chemical absorption liquid injected into the liquid tank can fully contact with the treated gas, thereby achieving efficient absorption of carbon dioxide. The selection of chemical absorption liquid can react chemically with carbon dioxide in a targeted manner, stably fixing it in the liquid, thereby improving the collection efficiency of carbon dioxide.

[0015] Furthermore, an air pump and a second connecting pipe are provided between the device body and the liquid tank. The second connecting pipe runs through the air pump, and a check valve is installed on the second connecting pipe.

[0016] Furthermore, a plurality of pores are provided on the surface of the aeration tube for dividing the treated gas.

[0017] Furthermore, the collection component is detachable from the device body, and the carbon dioxide adsorbent is an amine-functionalized activated carbon material.

[0018] By adopting the above technical solution, the collection component and the main body of the device are disassembled, which means that when a part of the collection component needs to be replaced or repaired, it can be easily removed from the main body of the device without disassembling the entire device. The amine-functionalized activated carbon material has excellent adsorption performance as a carbon dioxide adsorbent. Activated carbon itself is a highly efficient adsorbent, and amine functionalization can enhance its selective adsorption capacity for carbon dioxide. This means that the adsorbent can more effectively capture carbon dioxide from the mixed gas, improving the collection efficiency and purity of the device.

[0019] Furthermore, the pre-filter is detachably connected to the outer shell, and the outer shell is detachably fixedly connected to the air intake pipe via a flange.

[0020] Furthermore, the chemical absorption liquid is any one of an alkali solution and an amine solution.

[0021] By adopting the above technical scheme, alkaline solution and amine solution are both commonly used chemical absorbents with good absorption capacity for carbon dioxide. These chemical absorption liquids can react chemically with carbon dioxide, thereby stably fixing it in the liquid. Compared with the physical adsorption method, chemical absorption can capture and fix carbon dioxide more efficiently, thereby improving the collection efficiency of the device.

[0022] Furthermore, the mounting frame is cross-shaped and made of stainless steel. The mounting frame is fixed to the housing by welding, and the mounting frame and the induced draft fan are fixed and disassembled by bolts.

[0023] By adopting the above technical solution, the mounting frame is designed into a cross shape, which can provide stable support. Especially when it is necessary to support important components such as induced draft fans, the cross structure can effectively disperse and resist external forces from different directions to ensure the stable operation of the device.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] 1. The utility model installs a carbon dioxide monitor on the air intake pipe. When the induced draft fan is started, the air passes through the carbon dioxide monitor, which can monitor the carbon dioxide content in the inhaled air at all times. The staff can determine whether the collection device is working by observing the carbon dioxide content. When the carbon dioxide content is at a low value, the staff can turn off the collection device to reduce the power consumption of the device, and wait for the carbon dioxide content in the air to recover, and then start it again after a period of time, which is conducive to maintaining efficient collection of the device after startup;

[0026] 2. The utility model can pre-filter the incoming air by setting a pre-filter, improve the cleanliness of the air, reduce the replacement frequency of the filter in the collection component, facilitate operation, and also reduce the cleanliness of the induced draft fan blades and reduce dust adsorption;

[0027] 3. The utility model arranges chemical adsorption liquid in the liquid tank and divides the gas after the primary adsorption into a plurality of bubbles through the aeration pipe, so that the gas after the primary adsorption is fully mixed with the chemical adsorption liquid, which is beneficial to cleanly adsorb the residual carbon dioxide in the gas.

The various components in the device, such as the pre-induced draft mechanism, carbon dioxide monitor, etc., can be independently disassembled and replaced, which improves the modularity and maintainability of the device. When a component fails or needs to be replaced, it can be quickly disassembled and replaced, reducing downtime and improving the operating efficiency and service life of the device.

[0039] See also Figure 2 A collecting component 8 is installed inside the device body 1. The collecting component 8 includes two filter screens 81 arranged in parallel up and down and a carbon dioxide adsorbent 82 located between the two filter screens 81. The filter screens 81 and the carbon dioxide adsorbent 82 form an efficient adsorption and collection mechanism. The filter screen 81 can preliminarily filter large particles of impurities in the air to ensure that the gas entering the adsorbent is purer, while the carbon dioxide adsorbent 82 can selectively adsorb carbon dioxide molecules, thereby achieving effective collection of the target gas. The collecting component 8 has certain flexibility and scalability, and the number of filter layers and the type or quantity of adsorbents can be adjusted according to actual needs to meet the collection needs of carbon dioxide with different concentrations and flow rates.

[0040] See also Figure 1 , Figure 2 A first connecting pipe 2 is installed on the top of the device body 1. The first connecting pipe 2 is threadedly connected to the lower end of the front air induction mechanism 3. A sealing ring is provided at the connection between the first connecting pipe 2 and the front air induction mechanism 3. The threaded connection method makes the connection between the first connecting pipe 2 and the front air induction mechanism 3 very convenient. When installation or removal is required, it can be completed by rotating the corresponding parts without using additional tools or complicated operation steps. It not only improves the efficiency of installation and removal, but also helps to reduce the risk of damage caused by improper operation.

[0041] See also Figure 2The liquid tank 6 is filled with chemical absorption liquid 61, an air outlet pipe 62 is arranged on one side of the liquid tank 6, an aeration pipe 63 is arranged on the lower part of the liquid tank 6, and the aeration pipe 63 is a curved structure. The surface of the aeration pipe 63 is provided with a plurality of pores for dividing the treated gas. The chemical absorption liquid 61 injected into the liquid tank 6 can fully contact with the treated gas, thereby realizing efficient absorption of carbon dioxide. The selection of the chemical absorption liquid can react chemically with carbon dioxide in a targeted manner, stably fix it in the liquid, and improve the collection efficiency of carbon dioxide. The aeration pipe 63 with a curved structure can evenly distribute the gas to the bottom of the liquid tank 6, so that the gas is fully mixed with the chemical absorption liquid during the rising process. It is helpful to increase the contact area and time between the gas and the liquid, and promote the mass transfer and reaction process between carbon dioxide and the chemical absorption liquid.

[0042] See also Figure 1 , Figure 2 An air pump 7 and a second connecting pipe 9 are provided between the device body 1 and the liquid tank 6. The second connecting pipe 9 runs through the air pump 7. A check valve 91 is installed on the second connecting pipe 9. The check valve 91 is used to prevent liquid reflux. The air pump 7 can improve the efficiency of air extraction.

[0043] Embodiment 2:

[0044] See also Figure 2 The collecting component 8 is detachable from the main body 1 of the device. The carbon dioxide adsorbent 82 is an amine-functionalized activated carbon material. The collecting component 8 is detachable from the main body 1 of the device. This means that when a part of the collecting component, such as the carbon dioxide adsorbent, needs to be replaced or repaired, it can be easily removed from the main body of the device without disassembling the entire device. The amine-functionalized activated carbon material has excellent adsorption performance as a carbon dioxide adsorbent. Activated carbon itself is a highly efficient adsorbent, and amine functionalization can enhance its selective adsorption capacity for carbon dioxide, which means that the adsorbent can more effectively capture carbon dioxide from the mixed gas, improving the collection efficiency and purity of the device. The amine-functionalized activated carbon material generally has good recyclability and regeneration. When the adsorbent is saturated, its adsorption capacity can be restored through an appropriate regeneration process, thereby realizing the recycling of resources, which not only helps to reduce waste generation, but also reduces operating costs, and meets the requirements of environmental protection and sustainable development.

[0045] See also Figure 2The chemical absorption liquid 61 is any one of an alkali solution and an amine solution. Both alkali solution and amine solution are commonly used chemical absorbents and have good absorption capacity for carbon dioxide. These chemical absorption liquids can react chemically with carbon dioxide, thereby stably fixing it in the liquid. Compared with the physical adsorption method, chemical absorption can capture and fix carbon dioxide more efficiently, thereby improving the collection efficiency of the device. When absorbing carbon dioxide, alkali solution and amine solution have weak absorption capacity for other gases, so they have better selectivity. This helps to reduce the impact of other impurity gases on the carbon dioxide collection process and improve the purity of the collected carbon dioxide.

[0046] See also Figure 2 The mounting frame 32 is cross-shaped and made of stainless steel. The mounting frame 32 is welded and fixed to the housing. The mounting frame 32 and the induced draft fan 31 are fixed and installed by bolts. The mounting frame 32 is designed to be cross-shaped. This structure can provide stable support. Especially when it is necessary to support an important component such as the induced draft fan 31, the cross-shaped structure can effectively disperse and resist external forces from different directions to ensure the stable operation of the device. The mounting frame 32 and the housing are fixed by welding. This method is not only firmly connected, but also can effectively prevent loosening caused by vibration or external force. At the same time, the mounting frame and the induced draft fan 31 are fixed and installed by bolts, making the installation and removal of the induced draft fan simple and quick, and convenient for daily maintenance and replacement.

[0047] The implementation principle of the utility model is as follows: first, the device body 1 and the liquid tank 6 are installed, and then the carbon dioxide monitor 5 and the induced draft fan 31 in the front induced draft mechanism 3 are started, and the induced draft fan 31 absorbs air in the air. When the air passes through the carbon dioxide monitor 5, the carbon dioxide content in the air can be monitored, and the staff can observe the data of the carbon dioxide monitor 5. When the content is high, the induced draft fan 31 is kept working, and the air can be filtered once through the front filter 33 to filter out large particles of impurities in the air;

[0048] After that, the air enters the device body 1, passes through the filter screen 81, and is filtered twice. The carbon dioxide adsorbent 82 can absorb the carbon dioxide in the air. After that, the air passes through the second connecting pipe 9 and enters the liquid tank 6. The liquid tank 6 is injected with a chemical absorption liquid 61. This absorption liquid can react chemically with the carbon dioxide in the gas to further stabilize and adsorb carbon dioxide molecules. At the same time, the gas is divided into a number of bubbles through the aeration pipe 63, so that the gas and the chemical absorption liquid 61 are fully contacted and mixed, which helps to improve the adsorption efficiency of carbon dioxide and ensure that the carbon dioxide in the gas is adsorbed as completely as possible. Finally, the remaining gas is discharged through the outlet pipe 62;

[0049] The staff can observe the data on the carbon dioxide monitor 5 to determine the current carbon dioxide concentration level and decide whether it is necessary to adjust the operating status of the device. When the carbon dioxide content is low, the staff can choose to shut down the device to save energy; when the carbon dioxide content returns to a higher level, restart the device for collection.
