Description

Technical Field

[0001] This application relates to the field of gas experimental apparatus technology, specifically an atmospheric pollution simulation experimental apparatus. Background Technology

[0002] Air pollutants enter the atmosphere from anthropogenic or natural sources (input), participate in the atmospheric cycle, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities, and physical deposition (output). If the output rate is less than the input rate, they will accumulate relatively in the atmosphere, causing an increase in the concentration of certain substances. When the concentration increases to a certain level, it will directly or indirectly cause acute or chronic harm to people, organisms, or materials.

[0003] In order to control air pollution, targeted research is needed to provide environmentally friendly and efficient pollutant treatment solutions for practical industrial applications, reducing energy consumption and environmental pollution. Therefore, simulation experimental devices are needed for testing.

[0004] For example, patent CN110836785 A discloses a simulation device for air pollution control. This patent can precisely control the amount of various pollutants introduced into the experiment. By controlling the amount of pollutants introduced into the inner glass chamber, the purpose of accurate testing can be achieved. The double-layered chamber reduces the impact of changes in the external environment on the internal test environment. Furthermore, the waste gas generated during the test is treated by the polluted gas purification device, which verifies the performance of the air handling equipment and treats the test waste gas in a timely manner, avoiding direct emission and pollution of the surrounding environment.

[0005] In the implementation of the aforementioned patent, by setting up detection components in the test chamber, the changes in gas concentration can be understood in real time. However, for high-precision detection tasks, it is necessary to perform liquid sampling operations in real time and send the samples to a specialized laboratory for measurement. Therefore, it is necessary to provide an atmospheric pollution simulation experimental device with liquid sampling function to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1 As shown, this application provides an atmospheric pollution simulation experimental apparatus, including a mixing mechanism 1, which is used to introduce various simulated gases to be tested in the atmosphere and a liquid absorbent for absorbing pollutant gases, and to mix the gases and the liquid absorbent.

[0029] like Figures 1-2 As shown, the mixing mechanism 1 includes a base 11, on which a tank 12 is fixedly installed. The tank 12 is used for mixing gas and liquid absorbent. A liquid supply mechanism 2 is provided on one side of the tank 12 for introducing liquid absorbent into the tank 12.

[0030] The liquid supply mechanism 2 includes a liquid pump 21 fixedly installed on the base 11. The input end of the liquid pump 21 is connected to a liquid pipe 22, which is connected to the storage tank of the liquid absorbent. At the same time, the output end of the liquid pump 21 is connected to the inside of the tank 12, so that the liquid absorbent can be introduced into the inside of the tank 12 through the liquid pump 21.

[0031] Meanwhile, a gas supply mechanism 3 is provided on one side of the tank 12, which is used to input the gas to be simulated into the tank 12.

[0032] The gas supply mechanism 3 includes a gas tank 31 located on one side of the tank body 12. An air inlet pipe 33 is connected to the outlet of the gas tank 31. A pressure reducing valve 32 is installed on the air inlet pipe 33. A metering pump 34 is also installed on the air inlet pipe 33, so that the gas in the gas tank 31 can be output quantitatively and stably through the metering pump 34.

[0033] Meanwhile, the end of the air inlet pipe 33 away from the gas tank 31 is connected to the inside of the tank body 12, so that the gas in the gas tank 31 can be introduced into the inside of the tank body 12 through the metering pump 34 and come into contact with the liquid absorbent.

[0034] In this application, at least two sets of gas supply mechanisms 3 are provided to accommodate the input of various gaseous substances, thereby simulating the real conditions in the air. The inlet pipes 33 of the multiple sets of gas supply mechanisms 3 are located at different positions in the tank 12. Taking two sets of gas supply mechanisms 3 as an example, the inlet pipes 33 of the two sets of gas supply mechanisms 3 are respectively located at the upper and lower ends of the tank 12, so that one set of inlet pipes 33 is located at the upper end of the liquid surface, while the other set of inlet pipes 33 is located inside the liquid absorbent. This allows gas to be input into the tank 12 from multiple directions, thereby improving the efficiency of the reaction between polluting gas and liquid absorbent.

[0035] To further improve the reaction efficiency between pollutant gases and liquid absorbents, such as... Figures 1-2 As shown, a tank cover 16 is sealed at the upper end of the tank body 12, and a motor 13 is fixedly installed on the tank cover 16. A stirring part 110 is fixedly installed on the output end of the motor 13. The stirring part 110 extends into the interior of the tank body 12, and a stirring blade (not shown in the figure) is fixedly installed at the end of the stirring part 110. Thus, under the drive of the motor 13, the stirring part 110 is adapted to rotate, and drives the stirring blade to rotate synchronously to stir the liquid phase absorbent, thereby improving the reaction efficiency of the pollutant gas and the liquid phase absorbent.

[0036] Meanwhile, an inner tank 17 is provided inside the tank body 12, where both liquid and gas are stored. A containment space is formed between the tank body 12 and the inner tank 17. A heating wire 18 is provided in this containment space. By energizing the heating wire 18, the heating wire 18 can heat the inner tank 17, thereby increasing the internal temperature of the inner tank 17 and improving the reaction efficiency of the pollutant gas and the liquid absorbent.

[0037] In this application, an exhaust pipe 14 is provided on the tank cover 16 to facilitate the discharge of excess gas, and a drain pipe 15 is provided at the bottom of the tank body 12 to discharge the waste liquid after the reaction is completed. It should be noted that a purification device (not shown in the figure) is connected to both the drain pipe 15 and the exhaust pipe 14 to prevent the discharged waste gas and waste liquid from polluting the environment.

[0038] To collect the liquid reacting inside tank 12 for convenient laboratory concentration testing, and thus to determine the absorption efficiency of the pollutant gas in the liquid absorbent, thereby providing a basis for the treatment of the pollutant gas, such as... Figure 2 as well as Figures 4-5 As shown, a liquid intake port 19 is connected to one side of the tank 12. The position of the liquid intake port 19 is lower than the liquid level of the liquid absorbent. At the same time, a liquid intake mechanism 4 is connected to the position of the liquid intake port 19. The liquid intake mechanism 4 is used to collect the liquid reacting in the tank 12 in real time.

[0039] The liquid dispensing mechanism 4 includes a liquid dispensing cylinder 42 fixedly installed at the liquid dispensing port 19. One end of the liquid dispensing cylinder 42 is provided with a front end hole 421, and the other end of the liquid dispensing cylinder 42 is provided with a rear end hole (not shown in the figure). The diameter of the rear end hole is larger than the diameter of the front end hole 421 and communicates with the front end hole 421.

[0040] Meanwhile, a liquid extraction tube 45 is provided at the lower end of the liquid extraction cylinder 42. The liquid extraction tube 45 is connected to the rear end hole, and a flexible tube 46 is connected to the liquid extraction tube 45. The flexible tube 46 is connected to the container holding the liquid, so that the liquid in the tank 12 can be introduced into the container through the liquid extraction tube 45.

[0041] Furthermore, a piston rod 41 is slidably disposed inside the rear end hole. The piston rod 41 is provided with a rear shaft 411 that mates with the rear end hole and a front shaft 413 that mates with the front end hole 421. A sealing ring 47 is sleeved on the front shaft 413 and a sealing ring 48 is sleeved on the rear shaft 411, thereby sealing the front end hole 421 and the rear end hole.

[0042] Meanwhile, a retaining ring 43 is fixedly sleeved on the outer ring of the liquid collection cylinder 42. A spring 44 is installed between the retaining ring 43 and the piston rod 41. Under the action of the spring 44, the front shaft 413 is in the position of the front end hole 421. The front end hole 421 can be sealed by the sealing ring 47 to prevent liquid from overflowing from the front end hole 421.

[0043] When liquid needs to be collected, manually pull the piston rod 41 outward so that the front shaft 413 enters the rear end hole. At this time, because the front end hole 421 loses its seal, the liquid flows out from the front end hole 421 through the liquid collection tube 45 and enters the container, thus completing the liquid collection.

[0044] After the liquid is extracted, release the piston rod 41 so that the front shaft 413 can re-enter the front end hole 421.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
