Description

Technical Field

[0001] This application relates to the field of carbon dioxide adsorption technology, and more specifically, to a carbon dioxide adsorption and desorption experimental device. Background Technology

[0002] The exact substance released by the human body that constitutes the core attraction in the behavior mechanism of mosquitoes' preference for biting humans is not yet fully understood. Although many studies have reported that carbon dioxide produced by human metabolism may be one of the key factors, which has been verified in some experiments, the full picture of this attraction mechanism still needs to be explored in depth. Current methods for releasing carbon dioxide on the market have obvious shortcomings: for example, supplying carbon dioxide with high-pressure steel cylinders, although the concentration is stable, is inconvenient to carry and expensive, making it unsuitable for experimental scenarios; producing carbon dioxide through chemical reactions (such as the reaction of sodium bicarbonate with acid) is easily affected by temperature and the ratio of materials used, and cannot release a stable concentration of carbon dioxide.

[0021] See Figures 1 to 4 The carbon dioxide adsorption and desorption experimental apparatus includes: The first air path module is connected to the adsorption module. The first air path module supplies air to the adsorption module. The supplied air must avoid containing too much oil, dust and other impurities. The adsorption module includes a porous resin structure 2, which can be a plate-like structure, sheet-like structure, or block structure formed by porous resin material. The porous resin structure 2 processes the air delivered by the first gas path module and adsorbs carbon dioxide from it. The porous resin structure 2 is the functional core of the adsorption module. Typically, a resin with a high specific surface area and pore size that matches the carbon dioxide molecules (such as amine-functionalized porous resin structure 2) is selected to ensure the adsorption efficiency of carbon dioxide in the air. The partitioned test chamber 7 is connected to the adsorption module and serves as the experimental carrier of the system. The adsorption module provides carbon dioxide to the mosquitoes inside the partitioned test chamber 7. The partitioned test chamber 7 is subsequently partitioned by the movable partition 8, providing basic structural support for the comparative experiment.

[0022] According to a specific embodiment of this application, the carbon dioxide adsorption and desorption test device includes a control module connected to the partition test chamber 7 and a second gas path module connected to the control module. The second gas path module supplies air to the control module. The partition test chamber 7 is located between the adsorption module and the control module. This structure is used to construct a comparative experiment between the carbon dioxide attraction group (adsorption module) and the carbon dioxide-free control group (control module): the air supplied by the second gas path module is not adsorbed by the porous resin structure 2 and is directly introduced into the control side of the partition test chamber 7; after a period of time, by comparing the number of mosquitoes gathered on both sides, the attraction effect of carbon dioxide on mosquitoes can be quantitatively demonstrated. At the same time, the temperature of the control module needs to be synchronized with the temperature of the adsorption module during desorption to eliminate the interference of temperature difference on mosquito behavior. The second gas path module has the same specifications as the first gas path module.

[0023] According to a specific embodiment of this application, the adsorption module includes an adsorption column 1, a porous resin structure 2, and a first temperature sensor 3. The adsorption column 1 is connected to a first gas path module. The porous resin structure 2 is filled inside the adsorption column 1. The first temperature sensor 3 is attached to the middle of the adsorption column 1. The adsorption column 1 is made of a thermally conductive transparent material. The first temperature sensor 3 monitors the temperature inside the column in real time. During adsorption at room temperature, the temperature needs to be stabilized at 25-30℃. During desorption, the temperature needs to be raised to 80-120℃ to provide a basis for starting and stopping the heater.

[0024] According to a specific embodiment of this application, the adsorption module further includes a first heater 14, which is wrapped around the outer wall of the adsorption column 1. The first heater 14 can heat the adsorption column 1 and achieve intermittent heating to simulate the carbon dioxide release frequency of human respiration. When carbon dioxide is needed, the first heater 14 is activated to heat the adsorption column 1. When carbon dioxide is not needed, the first heater 14 is paused, allowing the porous resin structure 2 to adsorb carbon dioxide, forming an "adsorption-desorption" cycle to accurately simulate the carbon dioxide release pattern during human respiration.

[0025] According to a specific embodiment of this application, the adsorption module further includes a first filter screen 4 disposed at both ends of the adsorption column 1. The first filter screen 4 prevents the porous resin structure 2 from slipping out of the adsorption column 1. The first filter screen 4 can also filter dust particles in the air to avoid clogging the resin pores, thereby affecting its carbon dioxide adsorption efficiency and ensuring the stable operation of the device.

[0026] According to a specific embodiment of this application, the adsorption module further includes a flow valve 5 and a carbon dioxide concentration sensor 6. The flow valve 5 is connected to the adsorption column 1, the flow valve 5 is connected to the carbon dioxide concentration sensor 6, and the carbon dioxide concentration sensor 6 is connected to the partition test chamber 7. The flow valve 5 is used to adjust the carbon dioxide concentration. When the carbon dioxide concentration is insufficient, the flow rate is reduced to prolong the contact time between the air and the resin and increase the adsorption capacity. The carbon dioxide concentration sensor 6 is used to monitor the carbon dioxide concentration during desorption.

[0027] According to a specific embodiment of this application, a movable partition 8 is provided at the middle end of the partition test box 7. The movable partition 8 can separate the partition test box. Both the movable partition 8 and the partition test box 7 are made of transparent acrylic material, which is convenient for observing the behavior of mosquitoes. When the movable partition 8 is closed, the partition test box 7 is divided into two independent chambers. The chamber near the adsorption module is the treatment chamber (introduced with carbon dioxide that simulates human respiration), and the chamber near the control module is the control chamber (introduced with normal air). During the experiment, the partition is first opened, mosquitoes that have undergone starvation treatment are placed in, and left to stand for a period of time. Then the movable partition 8 is closed to observe the number of mosquitoes on both sides.

[0028] According to a specific embodiment of this application, an LED light 9 is provided at the top center of the partition test box 7 to simulate the low light environment indoors, so as to avoid strong light stimulating mosquito activity. The LED light 9 is installed in the center to ensure uniform lighting in both chambers and eliminate the influence of light difference on mosquitoes.

[0029] According to a specific embodiment of this application, the first gas path module includes an air pump 21, a drying tube 22, an airflow regulator 23, and a two-position three-way solenoid valve 24. The air pump 21 is connected to the drying tube 22, the drying tube 22 is connected to the airflow regulator 23, the airflow regulator 23 is connected to the two-position three-way solenoid valve 24, and the two-position three-way solenoid valve 24 is connected to the adsorption module. The air pump 21 is a miniature diaphragm pump to avoid noise interference with mosquito behavior. The drying tube 22 is used to remove moisture from the incoming air. The two-position three-way solenoid valve 24 is used to switch the gas path. During the adsorption stage, the dried air is introduced into the adsorption column 1. During the desorption stage, the air input is cut off, and the desorbed carbon dioxide is guided to the partition test chamber 7.

[0030] According to a specific embodiment of this application, the control module includes a control column 10, a second heater 11, and a second temperature sensor 12. The second heater 11 is wrapped around the outer wall of the control column 10, and the second temperature sensor 12 is attached to the middle of the control column 10. A second filter screen 13 is provided at both ends of the control column 10. The control column 10 has the same structure as the adsorption column 1, but the interior is not filled with a porous resin structure 2. The second heater 11 and the first heater 14 start and stop synchronously to keep the temperature of the control column and the adsorption column 1 consistent, thus eliminating the influence of temperature on mosquitoes. The second filter screen 13 and the second temperature sensor 12 have the same structure and specifications as the first filter screen 4 and the first sensor, and their functions are also the same.

[0031] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
