[0020] A method for manufacturing a device for adsorbing and desorbing carbon dioxide in multiple scenarios, comprising the following steps: S1: According to the requirements of the working scene, select the corresponding form of carbon dioxide adsorbent material 11 to be combined with the breathable grid 8. When the granular carbon dioxide adsorbent material 11 is selected, the granular carbon dioxide adsorbent material 11 is filled into the grid of the breathable grid 8 by vibration filling. The filling density of the granular carbon dioxide adsorbent material 11 in the breathable grid 8 after vibration filling is 90%. When the carbon dioxide adsorbent material 11 in the form of a coating is selected, the carbon dioxide adsorbent material 11 in the form of a coating is coated on the breathable grid 8 with a coating thickness of 1 mm.

[0022] In this embodiment, the present application is a working unit structure. A single working unit can intake air into the vortex structure through the air inlet 2. The vortex structure converts the input gas into a vortex. The vortex contacts the adsorption and desorption unit to improve the contact efficiency between the carbon dioxide adsorption material 11 and the air, and further improve the adsorption capacity. At the same time, the carbon dioxide adsorption and desorption device involved in the present application uses a flexible shell 1. When an external force is applied to the flexible shell 1, the flexible shell 1 produces a non-rebound deformation. When facing an arc-shaped mounting surface or a multi-faceted mounting surface, an external force can be applied to the flexible shell 1 until the flexible shell 1 forms an adaptive shape, so that the present application is not limited by the usage scenario. When facing a scene with a larger space, the number of working units can be increased according to the space size and purpose of the scene to improve the carbon dioxide adsorption and desorption efficiency in the scene.

[0023] like Figure 5As shown, the present application is arranged on the wall, and the flexible shells 1 are connected in pairs through male buckles 4 and female buckles 3, wherein the integrated air inlet pipe 12 and the integrated air outlet pipe 13 are each provided with three branch pipes, an air inlet 2 is communicated with a branch pipe of an integrated air inlet pipe 12, an air outlet 10 is communicated with a branch pipe of an integrated air outlet pipe 13, and a control line 14 is connected to the female buckle 3 at the head end, and a circuit is provided in each flexible shell 1. When the flexible shells 1 are connected in pairs through male buckles 4 and female buckles 3, the circuits between the flexible shells 1 are in a series state, and the workflow of the present application is as follows: Process 1: When the control line 14 outputs a cooling signal and current to the flexible shell 1 at the head end, each flexible semiconductor refrigeration sheet 5 performs cooling to reduce the temperature inside the flexible shell 1. The integrated air inlet pipe 12 inputs gas from the place where carbon dioxide needs to be absorbed to all air inlets 2 through a blower and other devices. The gas enters each air inlet channel 7 which is wide at the top and narrow at the bottom to increase the gas flow rate. The gas then enters the guide groove of the air duct and forms a vortex when flowing in the guide groove. The vortex is in full contact with the air permeable grid 8 with a spring-like spiral structure, and the carbon dioxide adsorption material 11 thereon is also in full contact with the air to adsorb carbon dioxide. At this time, air with a low carbon dioxide concentration enters the integrated air outlet pipe 13 from the air outlet 10 and is discharged into a place where air with a low carbon dioxide concentration is required.

[0024] Process 2: When the control line 14 outputs a heating signal and current to the flexible shell 1 at the head end, each flexible semiconductor refrigeration sheet 5 is heated to increase the temperature inside the flexible shell 1. The integrated air inlet pipe 12 inputs gas to all air inlets 2 through a blower and other devices. The gas enters each air inlet channel 7 which is wide at the top and narrow at the bottom, increasing the gas flow rate. The gas then enters the guide groove of the air duct and forms a vortex when flowing in the guide groove. The vortex is in full contact with the air-permeable grid 8 with a spring-like spiral structure, and the carbon dioxide adsorption material 11 thereon is also in full contact with the air to release carbon dioxide. At this time, air with a high carbon dioxide concentration enters the integrated air outlet pipe 13 from the air outlet 10 and is discharged into a place where air with a high carbon dioxide concentration is required.

[0025] In addition, the present application can also abandon the integrated air inlet pipe 12 and the integrated air outlet pipe 13, and directly place the device in a place where air with a low carbon dioxide concentration is required to adsorb carbon dioxide. After the adsorption is completed, the device can be transferred to a place where air with a high carbon dioxide concentration is required to heat and release carbon dioxide, for example: The carbon dioxide adsorption and desorption characteristics of the present application can be used for air freshening in indoor environments with poor air circulation. For example, in winter, offices often open windows for ventilation less frequently due to the cold outside air, resulting in a high indoor carbon dioxide concentration. The present application can be installed on the indoor wall, and the working units are connected in sequence to increase the carbon dioxide adsorption area in a flat manner. The present application can abandon the integrated air intake pipe 12, and form a multi-point large-area adsorption matrix by installing a fan at the air inlet 2 of each flexible shell 1 to efficiently adsorb indoor carbon dioxide, thereby reducing the indoor carbon dioxide concentration and ensuring the safe operation of the staff. At the same time, the carbon dioxide is transferred through the integrated air outlet pipe 13; The carbon dioxide adsorption and desorption characteristics of the present application can also be used in plant factories. When used in plant factories, the integrated air outlet pipe 13 can be discarded, and each working unit can be placed above or on the surrounding walls of each plant area, and a fan can be installed in each air outlet 10 to form a distributed carbon dioxide release system to improve the efficiency and range of carbon dioxide release. The carbon dioxide adsorbed in other places is then input into each working unit through the integrated air inlet pipe 12 for carbon dioxide desorption. The density of carbon dioxide is greater than the density of air, so the carbon dioxide will sink to the plant area, creating a carbon-rich environment for carbon-rich cultivation of plants; The present application can also be used in open mosquito catching places, such as park scenes. External force can be applied to the present application to cause deformation. After each working unit is connected and stacked, an artistic appearance is formed and then placed in the park, such as an animal appearance (deer, elephant, peacock, etc.) or a plant appearance (bamboo, flowers and trees, etc.) that matches the main body of the park. External force can also be applied to the present application to cause deformation that matches the park sculpture, and then the present application can be fixed on the park sculpture to achieve beauty and artistic sense while increasing the adsorption area and desorption area of ​​carbon dioxide. The present application can abandon the integrated air inlet pipe 12 and the integrated air outlet pipe 13, and adsorb carbon dioxide at the time when mosquitoes are not active (noon and afternoon), and desorb carbon dioxide at the time when mosquitoes are active (evening and early morning) to attract mosquitoes. The multi-point distributed working units increase the mosquito catching area, and with the help of mosquito killing devices such as power grids, mosquitoes can be killed on a large scale, thereby improving the mosquito killing efficiency.
