Abstract

The invention relates to a simulation processing system for volatile organic compounds. The processing system is used for evaluating the adsorption and regeneration performance of an adsorption material under the condition of simulating the actual engineering condition. The processing system comprises a gaseous VOCs (volatile organic compounds) generating device, a carrier gas introducing pipeline, a mixing device, an adsorption tower and a circulating fan, and further comprises a first concentration detector, a second concentration detector and a gas heating device, wherein the adsorption tower is provided with an air inlet and an air outlet. The processing system has a first use state and a second use state, namely adsorption treatment and desorption treatment are integrated; and when the adsorption material reaches a saturation adsorption state in the first use mode, the system can be immediately switched to the second use state and can perform simulation processing on different operating conditions (flow velocity, humidity and temperature), various kinds of waste gas treatment engineering conditions can be simulated to the largest extent, and therefore an optimal operation parameter is obtained, and the debugging cost of an enterprise in the practical engineering process is lowered.

Description

technical field [0001] The invention relates to a simulated treatment system for volatile organic compounds. Background technique [0002] At present, Volatile Organic Compounds (Volatile Organic Compounds, VOCs) refer to organic compounds that have relatively high vapor pressure and are volatile under normal temperature and pressure, mainly including alkanes, alkenes, aromatic hydrocarbons and various oxygen-containing hydrocarbons and nitrogen-containing hydrocarbons. , sulfur hydrocarbons, halogenated hydrocarbons, low-boiling polycyclic aromatic hydrocarbons, etc., are one of the main air pollutants. Studies have shown that VOCs and nitrogen oxides undergo a series of oxidation, condensation, nucleation and other processes in the atmosphere to form air pollutants mainly PM2.5. At the same time, most VOCs are highly toxic and irritating, which are harmful to human health and can damage the liver and nervous system. Some VOCs are also carcinogenic and genetically toxic. ...
