Description
Technical Field
The invention relates to the technical field of waste gas treatment equipment, in particular to an industrial harmful waste gas treatment device based on a VOCs biological method.
Background
The VOCs biological method is a process of decomposing organic matters into CO2 and H2O by using organic components in waste gas as a carbon source and an energy source under a proper environmental condition by microorganisms attached to a filter medium. VOCs (volatile organic compounds) in the bulk of the gas phase undergo mass transfer from the gas phase to the liquid or solid phase and are then broken down by microorganisms in the liquid or solid phase.
The common biological methods for treating VOCs are biological washing methods, and the biological washing process is a suspended activated sludge treatment system consisting of an absorber filled with inert fillers and an activated sludge reactor. The washing circulating liquid is sprayed from the top of the absorption chamber, so that pollutants and oxygen in the waste gas are transferred from a gas phase to a liquid phase through dissolution and adsorption, part of organic matters are directly degraded, most of the organic matters enter the activated sludge treatment system along with the washing liquid, the degradation of the organic matters is realized through the activated sludge system, and the washing circulating liquid is regenerated in the activated sludge system through aeration.
The biological washing process has the advantages that the resistance is low, the pressure is reduced, the packing layer is not easy to block due to larger porosity, the packing does not need to be replaced periodically, and the operation process and the reaction condition are easy to control. However, the method is suitable for treating easily soluble VOCs, such as alcohol and ketone (the Henry coefficient is less than 0.01), the concentration of pollutants is generally lower than 5000mg/Nm3, and the specific surface area of gas-liquid mass transfer is smaller (generally less than 300m 2. m < -3 >), so that the method is not suitable for treating waste gas with larger inlet gas flow, namely, the liquid phase resistance is larger and the gas-liquid mass transfer efficiency is low when the large-flow waste gas and the spray liquid contact and transfer mass in a biological washing method; meanwhile, for treating high-temperature waste gas, the mass transfer efficiency is low due to the fact that the rising speed of the high-temperature waste gas in the reaction chamber is high, and the contact time of the waste gas and a reaction medium is short, and therefore the industrial harmful waste gas treatment device based on the VOCs biological method is provided.
