Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically, it relates to a gas treatment device for removing carbon dioxide. Background Technology

[0002] Carbon dioxide is a colorless, odorless, and slightly acidic gas at normal temperature and pressure. It is a common greenhouse gas and a component of air. With the acceleration of modernization, carbon dioxide pollution is becoming increasingly serious. For example, greenhouse gases such as carbon dioxide in the atmosphere can radiate even longer wavelengths of radiation back to the ground after strongly absorbing long-wave radiation from the ground, causing the greenhouse effect. The intensifying greenhouse effect of the atmosphere leads to global warming and a series of global climate problems.

[0003] In existing technologies, some factories typically treat exhaust gases when emitting waste gas. There are many methods for removing carbon dioxide, a common one being the reaction of an alkaline solution with carbon dioxide to produce carbonates. However, this approach has some technical limitations, such as the difficulty in real-time monitoring of the alkaline solution's concentration, the inability to quickly disperse the waste gas within the solution, and the difficulty in cleaning up any precipitated crystals.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0005] Therefore, in order to solve the above problems, this utility model provides a gas treatment device for carbon dioxide removal. Utility Model Content

[0027] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0028] Please see Figure 1-3According to an embodiment of the present invention, a gas treatment device for carbon dioxide removal includes a treatment tank 1. A liftable tank cover 2 is installed at the top of the treatment tank 1. Two sets of symmetrically distributed vertical rods 201 are connected to the bottom of the tank cover 2. A base frame 202 is fixedly installed at the bottom of the vertical rods 201, and the base frame 202 can collect the precipitated solids. Two sets of symmetrically distributed lifting mechanisms 3 are installed on the treatment tank 1 to lift the tank cover 2. The lifting mechanisms 3 lift the tank cover 2, and as the tank cover 2 is lifted, the base frame 202 also rises from inside the treatment tank 1 and moves outside, facilitating the cleaning of the precipitated crystals. An agitation mechanism 4 is installed on the tank cover 2 to agitate the liquid inside the treatment tank 1, thereby ensuring that the gas is distributed more evenly in the liquid. A raw material addition box for adding raw materials and replenishing raw materials is installed at the top of the tank cover 2. 5. Potassium carbonate is pre-placed in the raw material addition tank 5. When carbon dioxide needs to be treated, a certain amount of water is injected into the treatment tank 1, allowing potassium carbonate to be injected from the raw material addition tank 5 into the treatment tank 1, dissolving in the water. Then, the gas to be treated is transported into the treatment tank 1, where carbon dioxide reacts with potassium carbonate, effectively separating carbon dioxide from the waste gas, reducing its emission concentration, and meeting environmental protection requirements. The stirring mechanism 4 can stir the solution, facilitating rapid diffusion of the waste gas in the solution when injected into the treatment tank 1, thus increasing the reaction rate. The tank cover 2 is also equipped with a concentration measuring mechanism 6 for detecting the concentration of the liquid in the treatment tank 1. The concentration measuring mechanism 6 can detect the concentration of the solution in the treatment tank 1, facilitating subsequent replenishment and addition of solute and solvent. A controller 9 is fixedly installed on the outer wall of the treatment tank 1.

[0029] like Figure 1 , 2 As shown, an air inlet pipe 101 is installed at the bottom of one side of the treatment box 1, and an exhaust pipe 102 is installed at the top of the other side of the treatment box 1. Both the air inlet pipe 101 and the exhaust pipe 102 are connected to the treatment box 1, and a valve is installed on the air inlet pipe 101. The exhaust gas can be injected into the bottom of the treatment box 1 through the air inlet pipe 101, and then flow from bottom to top. After reacting with the potassium carbonate solution in the treatment box 1, it is discharged through the exhaust pipe 102. The discharged exhaust gas can be input into other external equipment for treatment.

[0030] like Figure 2 As shown, a filter screen 203 is installed on the base frame 202. The filter screen 203 can retain the precipitated crystals on it and will not carry the solution out when the base frame 202 is raised.

[0031] like Figure 1 , 3As shown, the lifting mechanism 3 includes an installation groove 301 on the side wall of the processing box 1. An electric telescopic rod 302 is installed inside the installation groove 301. The output end of the electric telescopic rod 302 is connected to the bottom end of the box cover 2. The box cover 2 can be raised and lowered by the telescopic action of the electric telescopic rod 302, thereby saving manpower and facilitating the subsequent cleaning of the precipitated crystals on the base frame 202.

[0032] like Figure 1 , 2 As shown, the stirring mechanism 4 includes a motor 401 fixedly installed on the top of the tank cover 2. The output end of the motor 401 is connected to a stirring rod 402. Multiple sets of stirring blades 403 are fixedly installed on the stirring rod 402. The motor 401 drives the stirring rod 402 to rotate, and the stirring rod 402 drives the multiple sets of stirring blades 403 to rotate. The multiple sets of stirring blades 403 can stir the solution, so that when the waste gas is injected into the treatment tank 1, it can quickly diffuse in the solution and improve the reaction rate.

[0033] like Figure 1 , 3 As shown, the raw material addition box 5 includes a storage box 501 fixedly installed on the top of the box cover 2. A discharge pipe 502 is installed at the bottom of the storage box 501. An electric control valve 503 is installed on the discharge pipe 502. The outlet end of the discharge pipe 502 is connected to the processing box 1. By opening the electric control valve 503, the potassium carbonate stored in the storage box 501 can flow into the interior of the processing box 1 through the discharge pipe 502, which is convenient for manual operation.

[0034] like Figure 1 , 3 As shown, the concentration measuring mechanism 6 includes an online refractometer 601 fixedly installed on the top of the box cover 2. A signal line 602 is connected below the online refractometer 601. One end of the signal line 602 is connected to an optical probe 603. The concentration value is directly calculated by measuring the refractive index of the solution, utilizing the correspondence between optical refractive index and concentration.

[0035] like Figure 2 As shown, a high water level gauge 7 and a low water level gauge 8 are embedded inside the treatment tank 1. The high water level gauge 7 and the low water level gauge 8 can detect the liquid level of the solution in the treatment tank 1, thereby facilitating the operation of adding small amounts of water.

[0036] like Figure 1 As shown, a water inlet pipe 10 is installed on the top of the cover 2. One end of the water inlet pipe 10 is connected to an external water source, and a valve is installed on the water inlet pipe 10.

[0037] The working principle of this utility model patent for a carbon dioxide removal gas treatment device is as follows: A certain amount of potassium carbonate is pre-added to the treatment tank 1 through the raw material addition box 5, and then a certain amount of water is injected into the treatment tank 1 through the water addition pipe 10 to prepare a potassium carbonate solution. Then, waste gas is injected into the treatment tank 1 through the air inlet pipe 101. The waste gas mixes and reacts with the potassium carbonate solution, thereby removing carbon dioxide from the waste gas. The gas after carbon dioxide removal is discharged through the exhaust pipe 102. During this process, the motor 401 drives the stirring rod 402 to rotate, and the stirring rod 402 drives multiple sets of stirring blades 403 to rotate. The multiple sets of stirring blades 403 can stir the solution, thereby facilitating the rapid diffusion of the waste gas in the solution when it is injected into the treatment tank 1, improving the reaction speed. The reaction is further enhanced by the optical probe 603 and the online refractometer 601. In conjunction with the above, the concentration of potassium carbonate solution can be monitored online in real time. When the detected concentration is low, it transmits a signal to the controller 9. The controller 9 then opens the electrically controlled valve 503, allowing the material in the storage tank 501 to be injected into the treatment tank 1 through the discharge pipe 502. As the treatment tank 1 processes the waste gas, when the liquid level inside drops to the low water level gauge 8, it transmits a signal to the controller 9. The controller 9 then opens the valve on the water inlet pipe 10, allowing water to be injected into the treatment tank 1. When the water level reaches the high water level gauge 7, the valve is closed. When the solution in the treatment tank 1 is saturated and crystals precipitate, the processing of waste gas is stopped. The electric telescopic rod 302 drives the tank cover 2 to rise, thereby moving the base frame 202 to the outside of the treatment tank 1, making it convenient for staff to process the crystals precipitated on the base frame 202.

[0038] It should be noted that the electric telescopic rod 302, motor 401, electric control valve 503, online refractometer 601, signal line 602, optical probe 603, high water level gauge 7, low water level gauge 8 and controller 9 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.

[0039] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
