[0036] An embodiment of the present application, as Figures 1-7 shown, a temperature and humidity controlled adsorption and desorption reaction device for laboratory use includes an outer shell 1. The outer wall of the outer shell 1 is provided with a water inlet 101 and a water outlet 102. The water inlet 101 is arranged at the lower part of the outer shell 1, and the water outlet 102 is arranged at the upper part of the outer shell 1; the top of the outer shell 1 is provided with an air inlet 103, a humidification port 104, and a water filling port 105. The interior of the outer shell 1 is provided with a reaction chamber 2, a humidity generation chamber 3, and a humidity mixing pipe 4. The humidity generation chamber 3 and the humidity mixing pipe 4 are arranged at the upper part of the reaction chamber 2, and the bottom of the humidity mixing pipe 4 is communicated with the reaction chamber 2;
[0037] The humidifying port 104 and the water adding port 105 are respectively connected to the first inlet and the second inlet of the humidity generating chamber 3 through the humidifying pipeline 7 and the water adding pipeline 8. An inert gas (such as nitrogen) and pure water are respectively added to the humidity generating chamber 3 through the humidifying port 104 and the water adding port 105, and a humidity gas is formed.

[0039] Preferably, a connecting tee 9 is further included. The connecting tee 9 includes a first inlet, a second inlet and an outlet. The first inlet and the second inlet are respectively connected to the outlet pipeline 301 and the inlet pipeline 6, and the outlet is connected to the humidity mixing pipe 4 through a header pipe 11.
[0040] In another embodiment, it is also possible to directly connect the inlet pipeline 6 and the outlet pipeline 301 to the humidity mixing pipe 4, so that the humidity gas and the reaction gas are mixed in the humidity mixing pipe 4.
[0041] Further preferably, the inlet pipeline 6 and the humidifying pipeline 7 form preheating coils on the outer wall of the humidity mixing pipe 4. Among them, the inlet pipeline 6 forms a first preheating coil 601 on the outer wall of the humidity mixing pipe 4, and the humidifying pipeline 7 forms a second preheating coil 701 on the outer wall of the humidity mixing pipe 4, and the first preheating coil 601 and the second preheating coil 701 are wound around each other on the outer wall of the humidity mixing pipe 4; the setting of the preheating coils makes the lengths of the inlet pipeline 6 and the humidifying pipeline 7 in the housing 1 longer, so that the gas inside can be fully preheated before entering the humidity mixing pipe 4, and the temperature will be more uniform, thus promoting the progress of the reaction process; in addition, interference is eliminated and the stability of the gas temperature is ensured.

One end of the pressure detection pipe 10 extends out of the top of the housing 1, and the other end is connected to the humidity mixing pipe 4 for detecting the pressure of the mixed gas in the humidity mixing pipe 4 to achieve precise control of the adsorption and desorption experiment process.
[0043] Preferably, the housing 1 includes a housing body 107 and two end covers (the upper end cover 108 and the lower end cover 109) respectively arranged on the upper and lower parts of the housing body 107. The two end covers are respectively connected to the housing body 107 by screws.
[0044] Further preferably, a bracket 12 is further included. The housing 1 is installed on the bracket 12, and the bracket 12 and the housing 1 can be connected by screws for convenient disassembly.
[0045] Preferably, a reaction gas outlet 106 is provided at the bottom of the outer shell 1.

The provision of the connection joints enables detachable connection between the components, facilitating maintenance.
[0047] Working principle of the above embodiments:
[0048] Water is introduced into the outer shell 1 through the water inlet 101 of the outer shell 1, and heating is carried out by means of water bath temperature control; the reaction gas (CO2 or NOC gas) enters from the gas inlet 103 at the top of the outer shell 1, air and pure water enter the humidity generation chamber 3 through the humidification pipeline 7 and the water addition pipeline 8 respectively to form a humidity gas, then the reaction gas and the humidity gas are fully mixed in the humidity mixing pipe 4, and the humidity and temperature of the mixed gas in the humidity mixing pipe 4 are monitored in real time by the humidity and temperature detector 5. The mixed gas enters the reaction chamber 2 and reacts with the materials in the reaction chamber 2, so as to conduct experimental research on the adsorption and desorption ability of the materials for CO2 and NOC gases in a constant temperature and humidity environment;
[0049] In this application, constant temperature water is introduced into the outer shell 1 through the water inlet 101, so that the outer shell 1 forms a constant temperature water bath outer shell; then, during the experimental test, by adjusting the gas flow rate and the water bath temperature, an environment with different constant temperatures and different constant humidities in the reaction chamber 2 can be obtained, so as to study the adsorption and desorption ability of the materials for CO2 and NOC gases in a constant temperature and humidity environment.
[0050] This application provides an adsorption and desorption reaction device capable of providing a constant temperature and humidity environment. Compared with the prior art, in which large constant temperature and humidity chambers are often used for the adsorption and desorption research of constant temperature and humidity, the structure of this adsorption and desorption reaction device is innovative. First, it is small in size and compact in structure, directly subverting the previous design. The advantage of the small size is that it occupies less space, and the overall space is more suitable for the materials, enabling direct research on the surface properties of the materials; second, through reasonable structural design, the temperature and humidity control is more accurate, improving the experimental efficiency.
[0051] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly described should also be considered to be within the scope described in this specification.
