Problems solved by technology

Most of the existing laboratory detection devices can only detect the static adsorption performance of the adsorbent, and a small number of dynamic detection devices also have shortcomings. For example, the heat of adsorption and desorption of the adsorbent were not tested during the experiment; Two devices, the experimental process is likely to cause experimental data errors, and it is impossible to form an integration of adsorption and desorption dynamic testing
For example, the Chinese patent CN203894209U can only detect the dynamic adsorption performance of the adsorbent, but cannot perform the desorption test; the Chinese patent CN202562896U cannot test the heat of adsorption and desorption heat generated during the adsorption process

Embodiment Construction

[0027] When it is necessary to simulate the adsorption performance of the adsorbent in the industrial environment, this device is used to test the adsorption performance, and the adsorption performance under dynamic conditions is detected.

[0028] 1) Refer to figure 1 A dynamic detection device for adsorbent performance. In the figure of the experimental device, valves K1 to K12 are valves with different labels, and F1 to F2 are mass flowmeters with different labels, wherein each valve and mass flowmeter are instruments of the same model and function. Different labels are used to better describe the experimental device. The connection between the adsorption column and the multi-channel temperature tester is the temperature sensor connection line. The dotted line is the gas chromatograph analyzer GC for gas concentration test. figure 1 Connect directly, and the rest are gas pipelines. The experimental device is divided into two parts: adsorption test and desorption test, and ...

Description

technical field [0001] The invention belongs to the field of dynamic detection of adsorbent performance, in particular to a detection device for laboratory research on the adsorption and desorption performance of adsorbents on organic waste gas under dynamic conditions. Background technique [0002] Crude oil from extraction to refinery processing, and refined oil from refinery output to end-user consumption usually go through several storage, loading and unloading processes. In these processes, due to factors such as temperature, air pressure, and changes in the volume of the gas-liquid phase of the oil container, some of the oil and gas will volatilize into the atmosphere, resulting in loss of oil and gas, resulting in huge economic losses, environmental pollution, and potential dangers. And other issues. Foreign countries established the oil and gas recovery industry in the early 1970s, and my country also explored the oil and gas recovery work. Combining the current sit...
