Embodiment Construction
[0043] Below in conjunction with specific embodiment and appended Figure 1~6 , to further illustrate the present invention.
[0044] The present invention proposes a VOC waste gas comprehensive treatment system, as attached figure 1 As shown, including the adsorption unit and the natural gas boiler treatment unit, the natural gas boiler works intermittently:
[0045] When the natural gas boiler is not working, after the VOC exhaust gas passes through the first heat exchanger 1 to control the temperature, the temperature of the airflow is reduced to 30-40°C, the airflow passes through the buffer tank 2 at a steady flow rate, and then enters the pre-filter 3, and then the airflow enters the system 1 for adsorption Adsorber 4-1 and system two adsorber 4-2 are adsorbed, and the non-polluting gas after adsorption is discharged through the summary discharge port 5; in this embodiment, between the system one adsorber 4-1 and the system two adsorber 4-2 Set the series / parallel valv...

The invention relates to a waste gas comprehensive treatment system, and belongs to the field of environmental protection equipment. The VOC waste gas comprehensive treatment system is provided with adsorption systems capable of alternately working, wherein part of the adsorption systems perform adsorption, and part of the adsorption systems perform desorption. According to the present invention, waste gas is subjected to incineration treatment by using a natural gas boiler, and the boiler combustion tail gas heat returns to the adsorption system through the comprehensive integrated design so as to promote the desorption of the adsorption system; by using the alternating and parallel dynamic adsorption-desorption workflow of the multi-adsorption system, the long-term work can be ensured, the desorption problem of the adsorption system can be solved, and the desorption of each adsorption system can be achieved without affecting the normal working of the system; and various adsorption systems are switched, the waste concentrations, the gas flows and other conditions under different working conditions of the plant are combined, and the comprehensive design is adopted, such that different adsorption efficiencies of the adsorption system at the adsorption stage are combined with the fluctuation of the waste gas concentration so as to ensure the higher adsorption amount and the high adsorption efficiency.
Description
technical field [0001] The invention relates to waste gas treatment, in particular to a VOC waste gas comprehensive treatment system. Background technique [0002] Volatile organic compounds, abbreviated as VOC (Volatile Organic Compounds), are usually used as solvents in industrial production, and are released into the atmosphere through various channels after use, causing pollution to the environment. Among them, the chemical industry is the most widely used of such volatile organic solvents, and the VOC gas released continuously contains various biologically toxic aliphatic compounds, halogenated hydrocarbons and aromatic compounds, etc., which has brought serious health problems to residents. threat. In this kind of VOC gas with high biological toxicity, the components such as benzene and halogenated hydrocarbons have serious consequences such as carcinogenicity and teratogenicity on multiple organs, nervous system, and bone development of the human body. Therefore, the...
